GRE填空中常见的并列转折词有哪些:

  1. 并列关系(等价/递进/因果)

    等价、递进、因果和并列关系虽然名称各异,却殊途同归,因为在句意都属于并列关系,很像同义词之间的关系。等价关系通常由定语从句,同位语(或同位语 从句),或解析性从句引出,起着修饰,限制或者补充的作用。而递进和并列结构通常由一些衔接连词连接而成,关系一般都比较明显。所以,我们可以通过这些等 价成分得出句子空格应该填入的词,即关键词的同义词。

    常见的并列连词有:in that, additionally, again, moreover, further, furthermore, in the same manner, as well as, along with, furthermore, in the same way, just as, also, likewise, in addition to, like, similar to, similarly, for example, for instance, as an example, namely, that is。

    常见的因果关系过渡词有:because, because of, as a result, therefore, consequently, in consequence, hence, thus, since, so that, in order to。

  2. 转折关系

    转折关系正好与并列关系相反。如果说求解并列关系和因果关系句子的关键是寻找同义词的话,那么转折关系就是寻找反义词。只要你能识别这些转折关系词,问题就变得相当简单。转折关系词包括转折连词和负面语气词。

    常见的转折连词有:although, but, however, instead, nevertheless, on the other hand, rather than, though, otherwise, rather, despite, in spite of,whereas, even if, while.

    常见的负面语气词包括:curiously, ironically, paradoxically, far from, in deed, actually, in fact, compared with, unlike.

But this year I have received several pieces of Christmas gifts, gifts received the moment, indescribably happy!

If sport is, in essence, play, the claim might be made that sport is much older than humankind, for , as we all have observed, the beasts play. Dogs and cats wrestle and play ball games. Fishes and birds dance. The apes have simple, pleasurable games. Frolicking infants, school children playing tag, and adult arm wrestlers are demonstrating strong, transgenerational and transspecies bonds with the universe of animals - past, present, and future. Young animals, particularly, tumble, chase, run wrestle, mock, imitate, and laugh (or so it seems) to the point of delighted exhaustion. Their play, and ours, appears to serve no other purpose than to give pleasure to the players, and apparently, to remove us temporarily from the anguish of life in earnest.Some philosophers have claimed that our playfulness is the most noble part of our basic nature.   In their generous conceptions, play harmlessly and experimentally permits us to put our creative forces, fantasy, and imagination into action. Play is release from the tedious battles against scarcity and decline which are the incessant, and inevitable, tragedies of life. This is a grand conception that excites and provokes. The holders of this view claim that the origins of our highest accomplishments ---- liturgy, literature, and law ---- can be traced to a play impulse which, paradoxically, we see most purely enjoyed by young beasts and children. Our sports, in this rather happy, nonfatalistic view of human nature, are more splendid creations of the nondatable, transspecies play impulse. 英文作文 篇3   Tanabata, to mention the name will make people think of the story of the Cowboy Weaver Tianyuan meet.

英语填空的技巧和方法

英语填空的技巧和方法 英语填空的技巧和方法,在英语考试中,英语填空是比较难的一种题型。如果在英语考试中遇到语法填空题,可能就很容易写错了。那有哪些技巧方法呢?现在分享几种实用的英语填空的技巧和方法。 英语填空的技巧和方法1 英语语法填空解题策略 1、给出动词基本形态,填写词性词形转化(转为名词、形容词),或填写谓语部分,或是填写非谓语动词; 2、给出词语,词性的变化,如名词、动词、形容词、副词之间的转化,名词的复数形式,给出形容词,需要填写比较级、最高级,或词性词形转化,转化为副词,或是填写反义词(前缀); 3、给出副词,填写比较级、最高级,或是填写反义词; 4、不给词语填写限定词的时候,很可能是填冠词、人称代词主格宾格形式,物主代词、反身代词的单复数形式。形容词性物主代词或some、any、other、another等限定词;有的名词前有限定词,比如:序数词,形容词的最高级等,其前用定冠词。 语法填空答题方法 1、名词形式变化 名词的形式变化主要有单数、复数、所有格的变化。 例:there are many students living at school,the(child)houses are all far from schoo1. 由students一词可以判断出横线处应填复数,且作为houses的定语,所以应用其所有格形式,故答案为child的复合变化形式——复数的所有格children"s。 2、动词形式变化 动词的形式变化比较多,有谓语的变化(时态、语态、语气),有非谓语的变化(不定式、动名词、现在分词、过去分词)。 例:a talk(give)tomorrow is written by profess or zhang. 句中的iswritten是整句的谓语,所以横线所在的动词应当用作非谓语。从tomorrow可以看出,报告是“将来”作的,故用不定式;且报告是give动作的承受者,故可以判断出横线所在处用give的不定式被动式——to be given。 3、代词形式变化 代词形式变化通常是与人称变化有关的三大类五小类,即人称代词(主格和宾格)、物主代词(形容词性和名词性)、反身代词。另外还有几个不定代词的形式变化,如noone/none、other/another等。 例:the kingd ecided to see the painter by(he). 由介词by可以看出,横线处应填反身代词himself。 4、形容词、副词比较级变化 英语中大部分形容词和表方式的副词都有原级、比较级和最高级的变化。构成比较级和最高级的方式,或通过加后缀一er和.est,或在词前imore/less和most/least,且形容词的最高级还要冠以the。 例:i am——(tall)than liu wen.he is the tallest students in myclass. 此题后句交代了liuwen是班上最高的学生,那“我”肯定比他矮,所以不能用taller,只能用表示程度不如的“lesstall”。 英语语法填空口诀 1、接不定式作宾语的动词 三个希望两答应:hope,wish,want,agree,promise 两个要求莫拒绝:demand,ask,refuse 设法学会做决定:manage,learn,decide 不要假装在选择:petend,choose 2、句子种类口诀 句子按用途分四大体,陈述疑问感叹和祈使。 陈述用来叙述一件事。疑问主要用来提问题。 祈使表达命令和请求。表达强烈感情感叹句。 上述九是句种之定义。祈使主语you被抛弃。 若将其变成否定形式,动词之前加don"t是正理 3、冠词基本用法 名词是秃子,常要戴帽子, 可数名词单,须用a或an, 辅音前用a,an在元音前, 若为特指时,则须用定冠, 复数不可数,泛指the不见, 碰到代词时,冠词均不现。 冠词是中考必考的语法知识之一, 也是中考考查的主要对象。 英语填空的技巧和方法2 1、重复的基本规律:点对点 2、攻其一点,不及其余 3、读题干的策略:先读主干,再读分隔 4、分析的策略:a、分析句子结构b、定位中心词和逻辑关系c、选词d、理解句意 5、分析的具体方法——分隔与粘连 6、分隔结构通常为定语从句,同位语从句,分词结构,大的介词短语结构,GRE英语填空方法总结。分隔结构一旦出现,则成为其前空格的"答案,或者这些分隔中本身有空格,则应该从分隔前的结构中寻找信息。 7、如果分隔中或者分隔前都没有空格出现,这个分隔就是一个无用的分隔,一个冗余的信息,阅读时跳过去。 8、有时分隔结构会出现在主从句中,比如因果句中的because之后为逗号,不直接出现原因从句,而先出现分隔;或者although之后先出现分隔,然后再出现真正的转折从句等等。一律先跳过分隔,将真正的因果,转折,并列等主干逻辑读出来。 9、粘连指以分号,逗号,冒号分开的上下两句中的各种重复关系。她包括: a、直接重复 b、肯定与否定重复双重否定的标志:“it is wrong / presumptuous / irony / paradoxically / foolish to say that...”或者将paradoxically, irony, puzzingly, surprisingly等单词提前。 c、主动被动重复一般用by来引导,A-àB,Bàby A;或者将by换为三个短语代替:is the result of,is the outgrowth of,is the product of、此句基础上还可以变化为:非a->非B;Bàby A、 d、逆否重复AàB,B―>A、没有by,the result of,the outgrowth of,the product of等,其它考试《GRE英语填空方法总结》。 e、比较句重复 f、手段和目的A by BàB for A;by=in thems of; g、特殊并列句包括宾语从句,原因从句,同位语从句等一切从句的并列。此时解题就应该在两个并列从句之间进行推理,不必要考虑从句和主句之间的关系。 h、时间对比句 before, once, formerly, initial, pristine, erstawhile, hereto, hitherto, now, furture或者beging, start, create,或者until, no longer等。时间相反,一切对称成分相反。比如相反的时间有相反的动作,目的,原因,状态,观点等等。No longer,until要特别注意。 10、小连接:and,but,rather,even,as...as...,so as to连接对称的两个形容词,动词,副词或者不定式短语。 11、注意粘连中的人称代词,指示代词,定冠词。特别注意such,this,that,it,them,the这种词,可以帮助迅速找出对应关系。 12、粘连中的主体词汇:主体动词,表示人物身份的名词,描述人或者事物性质或者特征动作的词。 a、continue,remain这种转折是程度转折,引起程度上升用递进结构表达(even,almost),所以此处只能够是程度下降的转折。一般都是although dimilish/in retreat,之类的词,比较固定。与continue对应的主体动词还有shift from...to...,oscillate between...and,turn to,reconcile...and...等表示反面转折的动词。 b、critics的动作是judge,evaluate,praise,criticize,assail;doctor是salvage;scientist是disinterested, unbiased, impassive,下级对上级的指令永远服从。

急求《简·爱》小说梗概。作者背景知识。作品分析,文体风格,社会意义。英汉都要!!!!!!!!!!!

概述 《简·爱》创作于英国谢菲尔德,是一部带有自传色彩的长篇小说,它阐释了这样一个主题:人的价值=尊严+爱。《简·爱》中的简爱人生追求有两个基本旋律:富有激情、幻想、反抗和坚持不懈的精神;对人间自由幸福的渴望和对更高精神境界的追求。这本小说的主题是通过对孤女坎坷不平的人生经历,成功地塑造了一个不安于现状、不甘受辱、敢于抗争的女性形象,反映一个平凡心灵的坦诚倾诉的呼号和责难,一个小写的人成为一个大写的人的渴望。 《简·爱》是一部反响巨大的书。出版商在1847年10月就出版了这部作品。萨克雷称赞它是“一位伟大天才的杰作”。次年印行第三版时,《评论季刊》上提到“《简·爱》与《名利场》受到同样广泛的欢迎。乔治·艾略特则深深地被《简·爱》陶醉了”。写作特色 小说设计了一个很光明的结尾--虽然罗切斯特的庄园毁了,罗切斯特自己也成了一个残疾人,但我们看到,正是这样一个条件,使简·爱不再在尊严与爱之间矛盾,而同时获得满足--她在和罗切斯特结婚的时候是有尊严的,当然也是有爱情的。 这本小说告诉我们,人的最美好的生活是人的尊严加爱,小说的结局给女主人公安排的就是这样一种生活。虽然我们觉得这样的结局过于完美,甚至这种圆满本身标志着肤浅,但是我依然尊重作者对这种美好生活的理想--就是尊严加爱,毕竟在当今社会,要将人的价值=尊严+爱这道公式付之实现常常离不开金钱的帮助。人们都疯狂到似乎为了金钱和地位而埋没爱情。在穷与富之间选择富,在爱与不爱之间选择不爱。很少有人会像简这样为爱情为人格抛弃所有,而且义无反顾。《简·爱》所展现给我们的正是一种化繁为简,是一种返璞归真,是一种追求全心付出的感觉,是一种不计得失的简化的感情,它犹如一杯冰水,净化每一个读者的心灵,被认为是人生追求的二重奏。内容简介 这是一部具有浓厚浪漫主义色彩的现实主义小说,小说主要描写了简·爱与罗切斯特的爱情。主人公简·爱是一个心地纯洁、善于思考的女性,她生活在社会底层,受尽磨难。但她有倔强的性格和勇于追求平等幸福的精神。小说以浓郁抒情的笔法和深刻细腻的心理描写,引人入胜地展示了男女主人公曲折起伏的爱情经历,歌颂了摆脱一切旧习俗和偏见。扎根于相互理解。相互尊重的基础之上的深挚爱情,具有强烈的震撼心灵的艺术力量。其最为成功之处在于塑造了一个敢于反抗,敢于争取自由和平等地位的妇女形象。 《简·爱》是部脍炙人口的作品、毋庸置疑的名著。英国十九世纪著名的女作家夏洛蒂·勃朗特的代表作,当时人们普遍认为《简爱》是夏洛蒂·勃朗特“诗意的生平”的写照,是一部具有自传色彩的作品。一个有尊严和寻求平等的简·爱,这个看似柔弱而内心极具刚强韧性的女子也因为这部作品而成为无数女性心中的典范。 简·爱是个孤女,出生于一个穷牧师家庭。父母由于染上伤寒,在一个月之中相继去世。幼小的简寄养在舅父母家里。舅父里德先生去世后,简过了10年受尽歧视和虐待的生活。一次,由于反抗表哥的殴打,简被关进了红房子。肉体上的痛苦和心灵上的屈辱和恐惧,使她大病了一场。 舅母把她视作眼中钉,并把她和自己的孩子隔离开来,从此,她与舅母的对抗更加公开和坚决了。以后,简被送进了洛伍德孤儿院。 孤儿院教规严厉,生活艰苦,院长是个冷酷的伪君子。简在孤儿院继续受到精神和肉体上的摧残。由于恶劣的生活条件,孤儿院经常有孩子病死,她最好的朋友海伦在一次大的斑疹伤寒中去世了。这次斑疹伤寒也使孤儿院有了大的改善。简在新的环境下接受了六年的教育,并在这所学校任教两年。由于谭波尔儿小姐的离开,简厌倦了孤儿院里的生活,登广告谋求家庭教师的职业。 桑菲尔德庄园的女管家聘用了她。庄园的男主人罗切斯特经常在外旅行,偌大的宅第只有一个不到10岁的女孩阿黛拉·瓦朗,罗切斯特是她的保护人,她就是简的学生。 一天黄昏,简外出散步,邂逅刚从国外归来的主人,这是他们第一次见面。以后她发现她的主人是个性格忧郁、喜怒无常的人,对她的态度时好时坏。整幢房子沉郁空旷,有时还会听到一种令人毛骨悚然的奇怪笑声。 一天,简在睡梦中被这种笑声惊醒,发现罗切斯特的房间着了火,简叫醒他并帮助他扑灭了火。 罗切斯特回来后经常举行家宴。在一次家宴上向一位名叫英格拉姆的漂亮小姐大献殷勤,简被召进客厅,却受到布兰奇母女的冷遇,她忍受屈辱,离开客厅。此时,她已经爱上了罗切斯特。其实罗切斯特也已爱上简,他只是想试探简对自己的爱情。当他向简求婚时,简答应了他。 婚礼前夜,简在朦胧中看到一个面目可憎的女人在镜前披戴她的婚纱。 第二天,当婚礼在教堂悄然进行时,突然有人出证:罗切斯特先生15年前已经结婚。他的妻子原来就是那个被关在三楼密室里的疯女人。法律阻碍了他们的爱情,使两人陷入深深的痛苦之中。在一个凄风苦雨之夜,简离开了罗切斯特。在寻找新的生活出路的途中,简风餐露宿,沿途乞讨,历尽磨难,最后在泽地房被牧师圣·约翰收留,并在当地一所小学校任教。 不久,简得知叔父去世并给她留下一笔遗产,同时还发现圣·约翰是她的表兄,简决定将财产平分。圣·约翰是个狂热的教徒,打算去印度传教。他请求简嫁给他并和他同去印度。简拒绝了他,决定回到罗切斯特身边。 她回到桑菲尔德庄园,那座宅子已成废墟,疯女人放火后坠楼身亡,罗切斯特也受伤致残。简找到他并和他结了婚,得到了自己理想的幸福生活。

陈冯富珍总干事在中医现代化国际会议上的主旨演讲 1

The Contribution of Traditional Chinese Medicine to Sustainable Development 中医药对可持续发展的贡献 – Keynote Address at the International Conference on the Modernization of Traditional Chinese Medicine ——在中医现代化国际会议上的主旨演讲 Dr. Margaret Chan Director-General of the World Health Organization 世界卫生组织总干事 陈冯富珍博士 Singapore 23 October 2016 新加坡,2016年10月23日 Honourable ministers distinguished participants experts in traditional Chinese medicine ladies and gentlemen 尊贵的部长们,尊敬的与会者们,中医药领域的专家们,女士们,先生们: Every country in the world including an advanced nation like Singapore needs to be concerned about the sustainability of its health services. 世界每个国家,包括像新加坡这样的先进国家,都需要关注其卫生服务的可持续性问题。 Population ageing is now a universal trend affecting rich and poor countries in every region of the world. The globalized marketing of unhealthy products has made chronic nonmunicable diseases like heart disease cancer and diabetes the leading killers worldwide. 人口老龄化是当今一种普遍趋势,影响着世界各区域的富国与穷国。不健康产品的全球化营销已使心脏病、癌症和糖尿病等慢性非传染性疾病成为全世界的主要杀手。 Economic growth and modernization long associated with better health are now creating conditions that leave more and more people living longer sicker lives. 经济增长和现代化长期以来都与更好的健康联系在一起,而现在造成的局面是,越来越多的人虽然寿命延长了,却处于不健康的状态。 Most technology markets like those for flat screen TVs and hand-held electronic devices produce products that are progressively cheaper and easier to use. Not so for pharmaceuticals and medical devices where new products are nearly always more expensive and more plex to use often requiring specialized training. 大多数技术市场,如平板电视和手持电子设备市场,生产的产品越来越便宜和易于使用。但药品和医疗器械市场却不是这样,这类市场的新产品几乎总是更昂贵,使用起来更复杂,通常需要专门培训。 Even the richest countries in the world cannot afford new treatments for mon conditions like cancer and hepatitis C that cost from $50 000 to $150 000 per patient per year. 即使是世界最富裕的国家也负担不起用于癌症和丙型肝炎等常见病症的新治疗方法,这些疗法的费用每名患者每年为5万至15万美元。 This trend is the opposite of sustainable development. 这种趋势与可持续发展背道而驰。 At the same time a growing number of countries are reforming their health systems with the aim of reaching universal health coverage which is a key target under the Sustainable Development Goal for health. 与此同时,越来越多的国家正在改革其卫生系统,旨在实现全民健康覆盖,这是可持续发展目标下的一个主要卫生相关具体目标。 In other words countries are seeking to expand coverage with essential services at a time when consumer expectations for care are rising costs are soaring and most budgets are either stagnant or reduced. 换言之,在各国力求扩大基本服务覆盖面的同时,消费者对医护服务的期望在不断上升,费用在飞涨,而多数预算则停滞或缩减。 Faced with this dilemma and most especially the costs of treating lifestyle-related chronic diseases many experts see a need to shift the model for health service delivery away from a strictly biomedical model focused on individual diseases towards a more holistic approach. 面对这种困境,特别是鉴于治疗与生活方式相关的慢性疾病的费用,许多专家认为,需要将卫生服务的提供模式从注重个体疾病的严格生物医学模式转向更加全面的方法。 This is an approach that stresses prevention as well as cure offers integrated services that address the multiple determinants of health and asks people to take more responsibility for their own health. 这种方法不仅强调治疗也强调预防,并且提供综合服务以解决健康的多重决定因素,要求人们对自己的健康承担更多责任。 Apart from the need to do more for prevention some countries are looking for approaches that stop people with minor plaints from flooding waiting rooms at clinics and in emergency wards. 除了需要加强预防外,一些国家正在寻找办法,以避免有小病小痛的人蜂拥到诊所和急诊室。 In Europe for example pharmacists are trained to deal with mon aches pains sniffles and other plaints. They focus on symptoms not diseases and dispense over-the-counter products including herbal remedies to address these symptoms. In other words they act as gatekeepers. 例如,在欧洲,药剂师经过培训可以治疗常见的各种疼痛、感冒和其它小病。他们关注的是症状,而不是疾病,并分发非处方产品,包括草药,来治疗这些症状。换句话说,他们充当守门人的角色。 This is one way to reduce the burden on health services. Traditional Chinese medicine is another. 这是减少卫生服务机构负担的一种方法。另一种方法是中医药。 The World Health Organization weles this landmark conference on the modernization of traditional Chinese medicine. You seek in particular to give traditional medicine an evidence-based place within a health care system where mainstream modern medicine dominates. 世界卫生组织欢迎这次具有里程碑意义的中医药现代化会议。你们特别希望在主流现代医学占主导地位的卫生保健系统中为传统医学提供一个有证据基础的位置。 Your agenda says many things. You are looking at China"s experiences in clinics and hospitals where traditional and modern medicine offer integrated services at the role of health services and policy research and the use of biomedical knowledge to modernize traditional Chinese medicine. 此次会议议程的内容很多。你们要研究中国诊所和医院在提供中西医结合服务方面的经验,要审视卫生服务和政策研究的作用,并要讨论如何利用生物医学知识推动中医药现代化。 You are considering how more rigorous testing can meet the scientific standards needed for international recognition and acceptance. You are looking at the absolutely critical issue of safety as demonstrated in well-designed clinical trials. 你们要考虑如何通过更严格的检测来满足为获得国际认可和接受所必须的科学标准。从精心设计的临牀试验可以看出,你们在考虑极其重要的安全性问题。 You are also looking at the performance of traditional Chinese medicine for specific indications including digestive disorders and giving attention to the o forms of traditional medicine most often used in modern health systems namely acupuncture and herbal remedies. 你们还要查看中医药对特定适应症(包括消化系统疾病)的效果,并关注针灸和草药这两种现代卫生系统中最常用的传统医学形式。 All of these approaches can contribute to the modernization of traditional Chinese medicine. 所有这些方法都可推动中医药现代化。 I am Chinese and I have used traditional Chinese medicine throughout my lifetime. I have no doubt that these preparations soothe treat many mon ailments and relieve pain. 作为中国人,我一直都使用传统中药。我毫不怀疑这些药剂能缓解、治疗许多常见疾病,并减轻疼痛。 But if I have a bad toothache I go to the dentist. 但如果我牙痛难忍,我会去看牙医。 Ladies and gentlemen 女士们,先生们, One approach when exploring the modernization of traditional Chinese medicine is to look at the shortings of modern medicine both real and perceived. Paradoxically these shortings have created a situation where traditional medicine meets a perceived need yet earns a bad name at the same time. 在探讨中医药现代化问题时,可以审视一下现代医学的缺点,不论是真实的还是察觉到的。但奇怪的是,这些不足却导致了一种局面,就是传统医学满足了一种被很多人认可的需求,却得了个坏名声。 In wealthy countries the public often reacts in a negative way to health care that is seen as over-medicalized and over-specialized with the patient treated like a collection of specialized body-parts on an assembly line instead of a whole person. 在富裕国家,公众往往对过度医疗化和过度专业化的卫生保健有种消极反应,因为这类保健将患者当作装配线上一种专门身体部位的集合体而非一个完整的人来对待。 People want more control over what is done to their bodies. They want to self-regulate their own health. 人们希望能更多地掌控对其身体所作的治疗。他们希望对自己的健康进行自我调节。 As seen in the movement of vaccine refusal science is often mistrusted sometimes even vilified. Rumours spread via social media can carry more weight than hundreds of well-designed peer-reviewed research studies. 正如我们在拒绝疫苗接种的运动中所看到的,科学往往得不到信任,有时甚至遭到诋毁。通过社交媒体传播的谣言可能比上百份精心编写并获得同行审评的研究报告更具影响力。 People are suspicious that powerful new drugs may have side effects that have either not yet been detected or were never honestly disclosed. 人们怀疑效力强大的新药物可能具有尚未发现或从未诚实披露的副作用。 Some *** ysts attribute this dissatisfaction and mistrust to the system the infrastructure the training the incentives and the orientation of modern medical care. 一些分析师将这种不满和不信任归因于现代医疗保健的制度、基础设施、培训、奖励措施以及导向。 In many countries this system dictates that a doctor spend no more than around 20 minutes with each patient. In many outpatient clinics for primary care the time spent with patients is 5 minutes or less. 在许多国家,现代医疗保健制度要求医生用于每名患者的时间不得超过20分钟。而在许多初级保健门诊所,用于患者的时间仅5分钟或更短。 During these few minutes the doctor is expected to act not talk to order medicines tests and other interventions. This practice contrasts sharply with the approach used by traditional practitioners. 在这几分钟内,医生要行动,不要说话,要就药物、化验以及其它干预作出处方。这种做法与传统医学从业者的方法形成鲜明对比。 Moreover the number of doctors practicing family medicine continues to shrink dramatically in favour of more and better-paid specialists and sub-specialists. 此外,从事家庭医学的医生数量继续大幅减少,而出现了更多报酬更高的专科医生和亚专科医生。 Family physicians are a vanishing profession right at the time when the rise of nonmunicable diseases makes their skills essential for prevention and the continuity of sometimes life-long care. 随着目前非传染性疾病日益增多,家庭医生的技能对于这类疾病的预防和有时持续终生的连续护理至关重要,但这一职业却正在消失。 The phenomenal rise of the alternative medicine industry responds to some of these shortings in what modern medicine has to offer. In several North American and European countries the production and sale of herbal medicines dietary supplements and other so-called “natural” products have bee a huge and profitable industry amounting to $32 billion a year in the USA alone. 替代医学产业的惊人崛起弥补了现代医学中的一些不足之处。在若干北美和欧洲国家,草药、膳食补充剂以及其它一些所谓“天然”产品的生产和销售已成为一个巨大的赚钱产业。仅在美国,该产业的年业务额便达320亿美元。 The industry fiercely defends its territory its claims and its profits. Aggressive marketing that makes unsubstantiated claims has antagonized many in the medical establishment. 该产业极力捍卫自己的领域、权利和利润,通过一些毫无根据的声称展开积极营销,招致了医疗界中很多人的怨愤。 As medical professionals argue most alternative medicines are introduced onto the market via over-the-counter sales or the inter without any regulatory oversight. 医疗专业人士指出,大多数替代药物系通过非处方销售或因特网进入市场,不受任何监管。 These arguments point to the critical contribution regulatory authorities can make to the modernization of traditional Chinese medicine. A drive aimed at licensing and regulatory control can bring legitimacy to traditional remedies as has been done here in Singapore. 这些论点指出监管机构可以对中医药现代化做出重要贡献。针对许可证发放和监管控制采取行动可以使传统疗法具有合法性,新加坡已经这样做了。 Singapore has also pioneered some good policies that protect against some perceived dangers of traditional Chinese medicine. For example patients are referred for traditional treatments like acupuncture by doctors trained in Western medicine. 新加坡还开创了一些良好政策,帮助防止一些已察觉到的中医药危险。例如,将患者转诊给受过西医培训的医生进行针灸等传统治疗。 Having a doctor"s opinion as backup helps protect against the risk that what may seem to be unplicated plaints might actually be the early signals of a more serious condition. 征询医生的意见作为支持有助于防范风险,有些看起来似乎不太复杂的小病痛实际上可能是一个更严重病症的早期信号。

健康的英语诗

分类: 教育/科学 >> 外语学习 问题描述: 11月7日之前打 解析: 1 When sorrows e, they e not single spies, But in battalions.Give sorrow words; the grief that does not speak, Whispers the o"er-fraught heart and bids it break. Sorrow breaks seasons and reposing hours, Makes the night morning, and the noontide night. What private griefs they have, alas, I know not. My grief lies all within, And these external manners of lament Are merely shadows to the unseen grief That swells with silence in the tortured soul. It easeth some, though none it ever cured, To think their dolour others have endured. I will instruct my sorrows to be proud For grief is proud an"t makes his owner stoop. Day doth daily draw my sorrows longer, And night doth nightly make grief"s length seem stronger. What"s gone and what"s past help Should be past grief. Feed on her damask cheek: she pined in thought, And with a green and yellow melancholy She sat like patience on a monument, 2 Stopping by woods on a snowy evening Robert Frost Whose woods these are I think I know His house is in the village though He will not see me stopping here To watch his woods fill up with snow My little horse must think it queer To stop without a farmhouse near Beeen the woods and frozen lake The darkest evening of the year He give his harness bells a shake To ask if there is some mistake The only other sound"s the sweep Of easy wind and downy flake The woods are lovely, dark and deep But I have promises to keep And miles to go before I sleep 我想我知道这是谁的森林,尽管那人远在乡村 他不会看到我停留于此,欣赏这片属于他的 被皑皑白雪覆盖着的林园 我的小马必定奇怪,为什么要驻足在这里——远离人烟 游荡在森林和冰冻的湖水之间, 在一年中最阴暗的夜晚,那人摇响了他的马铃 询问一切是否平安 却只有风儿吹过,雪片飘零 这森林如此迷人幽深,可是我已许下诺言: 在我沉入梦乡之前,还要再走上一段, 还要再走上一段。 3 My favorite poem by Frost: Design I found a dimpled spider, fat and white, On a white heal-all, holding up a moth Like a white piece of rigid satin cloth-- Assorted characters of death and blight Mixed ready to begin the morning right, Like the ingredients of a witches" broth-- A snow-drop spider, a flower like a froth, And dead wings carried like a paper kite. What had that flower to do with being white, The wayside blue and innocent heal-all? What brought the kindred spider to that height, Then steered the white moth thither in the night? What but design of darkness to appall?-- If design govern in a thing so *** all. 4 Dylan Thomas Not really for me. I liked his "Before I Knocked", but unfortunately the wry sense of humor in this poem is more the exception than the rule. Too morbid, which is quite English; but the sober take-me-seriuosly earnestness is not English, at all. Because the English, from before Shakespeare"s time, has been known for a paradoxically life-affirming graveyard humor. which is not shared by Dylan Thomas at all. 5 Edward Thomas: Rain Rain, midnight rain, nothing but the wild rain On this bleak hut, and solitude, and me Remembering again that I shall die And neither hear the rain nor give it thanks For washing me cleaner than I have been Since I was born into this solitude. Blessed are the dead that the rain rains upon: But here I pray that none whom once I loved Is dying to-night or lying still awake Solitary, listening to the rain, Either in pain or thus in sympathy Helpless among the living and the dead, Like a cold water among broken reeds, Myriads of broken reeds all still and stiff, Like me who have no love which this wild rain Has not dissolved except the love of death, If love it be for what is perfect and Cannot, the tempest tells me, disappoint. 6 [This is the answer to your prayer, 隽饴] W. H. Davis: LEISURE What is this life if, full of care, We have no time to stand and stare? No time to stand beneath the boughs And stare as long as sheep and cows. No time to see, when woods we pass, Where squirrels hide their nuts in grass. No time to see, in broad daylight Streams full of stars, like skies at night. No time to turn at Beauty"s glance, And watch her feet, how they can dance. No time to wait till her mouth can Enrich that *** ile her eyes began. A poor life this if, full of care, We have no time to stand and stare. 7 Byron: "So We"ll Go No More a-Roving" So we"ll go no more a-roving So late into the night, Though the heart still be as loving, And the moon still be as bright. For the sword ouears its sheath, And the soul ouears the breast, And the heart must pause to breathe, And love itself have rest. Though the night was made for loving, And the day returns too soon, Yet we"ll go no more a-roving By the light of the moon. 8 This poem offers the rare bination of immediate appeal AND the potential for undiscovered depth, when you re-read it. For example, what is meant by these lines? Haply I may remember, And haply may fet. There are different ways you may read into these o lines. Amazing

让你的婚姻美满的小诀窍(双语图文)

Having been married for more than 40 years I can attest to the truth of the following statement: to excel in the art of domestic argument one must master the art of losing. 作为一个进入婚姻这座围城40多年的人,我可以证明下面这段陈述绝对是正确的——想要在家庭争论这门艺术中获得胜利,首先,你要掌握以退为进的艺术。   Modern psychologists are taken with the “win-win” solution. But in marriage success resides more in “lose-lose” solutions. Out of these both parties can win. For in the love configuration losing gives a gift that always returns. 现代的心理学家们都热衷于“双赢”的解决办法,而在婚姻中,成功者更多地采取的是“双输”的解决方案。通过这样,夫妻双方都可以是赢家。因为,在爱情的天空下,放低姿态永远是一份有回报的礼物。 One day shortly after my wife and I were married we set about picking new living-room wallpaper from a book of samples. My taste and hers were at odds. 婚后不久的一天,我和老婆正着手于从一本样品册子里挑选起居室的新壁纸。我和她有了分歧,我们各有自己喜欢的壁纸。 “I like this one ” she said. “That looks like a section of a diseased liver.” “How can you say that? This is a classical pattern that goes all the way back to the Veian.” “The Veian were blind. They named blinds after them remember? I like this one.” “I wouldn"t hang that in hell if I were the devil.”  “我喜欢这一种。”她说道。 “这种壁纸看起来就像一块患病的肝。” “你怎么能这样说?这种图案可是古典的古代威尼斯风格。” “威尼斯人是瞎子,他们以威尼斯来命名百叶窗(在英语中,盲人和百叶窗是同一个词——译者注),记得吗?我喜欢这一种。” “我死也不会用那一种壁纸来作装饰。”  As the argument went on my wife suddenly slammed the book shut. “There are over o hundred samples in this book ” she declared. “I say we spend our energy finding one that suits us both instead of bickering over the ones we don"t like.” 争论继续着,我老婆突然用力把册子一合,大声宣称:“这本册子里有200多种样品,我建议,我们还是花精力来找到一张我们都喜欢的样品,而不是用来对那些我们不喜欢的品头论足。”   And that"s how we settled it. Eventually we found a pattern we both liked. The “wallpaper book” became our symbol for settling the myriad issues that arise in marriage. “Well ” she"d say when we couldn"t agree on furniture or a place to vacation “there are plenty of samples in the wallpaper book.” 我们就这样解决了争论。最后,我们终于找到了一个我们俩人都喜欢的图案。壁纸样品册子成了一个典型事件,代表了我们解决婚姻中出现的无数问题的一个象征。当我们在购买家俱或去什么地方度假的意见不一致时,我的老婆就会说:“在壁纸样品册子里有大把样品可选。”   The issues that people argue over most in marriage such as how to spend money often aren"t the real ones. The key issue is: who is going to be in control? When I was younger my need to control arose out of fear a lack of trust insecurity. The day I finally realized I didn"t need to control my wife—that indeed I ought not control her that I couldn"t control her and that if I tried to I would destroy our marriage—was the day our marriage began. 人们在婚姻中争论的那些问题,诸如怎样花钱之类,往往并不是争论的真正问题所在。关键的问题是:谁是家里的当家人。当我比较年青的时候,我想当家是出于恐惧,是缺乏信任和安全感。当我终于意识到我不必支配我老婆的时候,我们的婚姻才算真正开始。确实,我不应该支配我的老婆,我也不能去支配她,如果我尝试这样去做,我将会毁了我们的婚姻。    Giving up control is often confused with weakness. But the winner in a domestic argument is never really the winner. When you win a battle and your partner submits you have paradoxically lost. 放弃支配对方常常与“妻管严”和“大男人”相混淆。但是,在家庭争吵中的赢家绝算不上是真正的赢家。当你赢得了一场口角,使你的人生伴侣顺从的时候,恰恰相反,你其实是输了。   What is it we want most from a marriage? To love and be loved. To be happy and secure. To grow to discover. A love relationship is the garden in which we plant cultivate and harvest the most precious of crops our own self and in which our spouse is provided the same rich soil in which to bloom. 我们在婚姻中最想得到的是什么?是爱与被爱,是快乐与安定,去成长、去增长见识。一段爱的关系就像一个花园,在这个花园里我们种植、培养和收获最宝贵的农作物——我们自己。在这个花园里,我们要给我们的配偶提供同样肥沃的土壤,让她或他茁壮成长。   We cannot obtain what we want unless our partner also gets what he or she wants. A woman may for instance want to go to the symphony. Her hu *** and might hate symphonies. But by spending a few hours listening to music he doesn"t care for he can bring joy to his partner. That"s a pretty cheap price to pay for joy isn"t it? 除非我们的人生伴侣也能得到他或她想要的,否则,我们不可能得到自己想要的事物。例如:一个女人可能想去听一场交响乐,而她的丈夫可能讨厌交响乐,但是,只要丈夫花几个小时去听一下他不热衷的音乐,就可以给他的伴侣带来欢乐,难道这不是一个换取快乐的很容易的办法吗?    But what if a hu *** and wants to go on a fishing trip with friends? Suddenly there aren"t a lot of samples in the wallpaper book: his wife either agrees or not. 但是如果丈夫想要和他的朋友们一起去钓鱼呢?突然之间,在墙纸样品册子中没有许多样纸可供挑选了——老婆只能选择“同意”或“不同意”。   Already you can hear the usual power strategies: “I"ll spend my money any way I please ” or “How e you"re such a millstone? Jim"s wife is happy that he gets to go.” 你应该已经听过以下常见的争权策略:“我可以按自己的心意来花我自己的钱。”或:“你怎么这样难缠?吉姆的老婆就很开通,他想去哪儿就去哪儿。” 想一想再看 n. 克制,控制,管制,操作装置 vt. 控制 想一想再看 vt. 培养,耕作,栽培,结交(朋友) 促进增长,教养 想一想再看 n. 软弱 想一想再看 n. 解答,解决办法,溶解,溶液 想一想再看 n. 声明,陈述 想一想再看 n. 图案,式样,典范,模式,型 v. 以图案 想一想再看 n. 搭档,伙伴,合伙人 v. 同 ... 合 想一想再看 n. 结构,布局,形态,格式塔心理完形 [计算机] 配置 想一想再看 vt. 获得,得到 vi. 通用,流行,存在 想一想再看 n. 不安全;不牢靠;无把握;心神不定

GRE填空中句子关系怎样判断

一.GRE填空答题过程中如何判断句子之间的逻辑关系GRE填空考察的就是整体逻辑语言的能力,考生的任务就是找出句子成分间的逻辑关系,并选择一个合理且必然的选项。句子成分间的逻辑关系对解题起着至关重要的作用,它们常常由一些明显的关键词提示。最重要的几种逻辑关系:因果关系:because, in that, for, therefore, thus, accordingly, consequently, hence, given, so…that, so…as to, when…then, as long as, in order to……转折关系:albeit, but, although, despite, however, in spite of, nevertheless, notwithstanding, while, whatever, regardless, even though, even if, yet……对比关系:in contrast, on the contrary, far from, on the other hand, rather than, instead of, not…but, paradoxically, ironically, surprisingly, unexpectedly……另外还有时间的不同体现相反的关系等。填空题的句子常出现陌生的专业术语,晦涩的思想观点等,但对解题并不构成真正的障碍。因为题目本身往往提供了足够的内容的重复线索帮助你找到正确的答案。e.g.Melodramas, which presented stark oppositions between innocence and criminality, virtue and corruption, good and evil, were popular precisely because they offered the audience a world _____ of _____.A. bereft theatricalityB. composed adversityC. full circumstantialityD. deprived polarityE. devoid neutrality题目的主干要我们填Melodramas提供给观众一个怎样的世界,同时又告诉我们它们表现了无辜与罪恶,美德与堕落之间的刻板对立,所以我们不需要知道Melodramas是什么东东就可以判断它们提供给观众的是一个刻板对立的世界,五个选项中只有E选项“全无中立的世界”表达了这个意思。The new biological psychiatry does not deny the contributing role of psychological factors in mental illnesses, but posits that these factors may act as a catalyst on existing physiological conditions and _____ such illnesses.A. disguise B. impede C. constrain D. precipitate E. consummate这道题粗看起来内容十分专业,空格要求填factors 对such illnesses 有什么样的动作。其实句子中有一个明确的重复线索,factors 起到了一个催化剂的作用,所以空格中填入一个表达催化意思的词语,就一定是正确选项。表示催化的感觉的词只有D项:precipitate二.GRE填空答题过程中如何判断语气和感情色彩有时,通过正常的阅读去理解句子比较难且费时间。但是用感情色彩去判断,处理起来就变得比较方便。e.g.Johnson never _____ to ignore the standards of decent conduct mandated by company policy if _____ compliance with instructions from his superiors enabled him to do so, whatever the effects on his subordinates.A. designed tacitB. attempted halfheartedC. intended directD. scrupled literalE. wished feigned句子的意思比较令人费解,但是从句末whatever the effects on his subordinates(不管对他的下级产生怎样的影响)看,我们知道Johnson做的是一件不好的事情。从第一个空格看,五个选项只有D的scrupled填入表达这样的意思。判断逻辑关系,寻找重复关系,判断语气及感情色彩这几步熟练的结合运用,几乎能解决所有的填空问题。

谁能介绍一下法国新艺术派Art Nouveau

Art Nouveau, 1890-1914, explores a new style in the visual arts and architecture that developed in Europe and North America at the end of the nineteenth century. The exhibition is divided into three sections: the first focuses on the 1900 World"s Fair in Paris, where Art Nouveau was established as the first new decorative style of the twentieth century; the second examines the sources that influenced the style; and the third looks at its development and fruition in major cities in Europe and North America.At its height exactly one hundred years ago, Art Nouveau was a concerted attempt to create an international style based on decoration. It was developed by a brilliant and energetic generation of artists and designers, who sought to fashion an art form appropriate to the modern age. During this extraordinary time, urban life as we now understand it was established. Old customs, habits, and artistic styles sat alongside new, combining a wide range of contradictory images and ideas. Many artists, designers, and architects were excited by new technologies and lifestyles, while others retreated into the past, embracing the spirit world, fantasy, and myth.Art Nouveau was in many ways a response to the Industrial Revolution. Some artists welcomed technological progress and embraced the aesthetic possibilities of new materials such as cast iron. Others deplored the shoddiness of mass-produced machine-made goods and aimed to elevate the decorative arts to the level of fine art by applying the highest standards of craftsmanship and design to everyday objects. Art Nouveau designers also believed that all the arts should work in harmony to create a "total work of art," or Gesamtkunstwerk: buildings, furniture, textiles, clothes, and jewelry all conformed to the principles of Art Nouveau.另一种介绍:Art Nouveau"An international style of decoration and architecture which developed in the 1880s and 1890s. The name derives from the Maison de l"Art Nouveau, an interior design gallery opened in Paris in 1896, but in fact the movement had different names throughout Europe. In Germany it was known as "Jugendstil", from the magazine Diejugend (Youth) published from 1896; in Italy "Stile Liberty" (after the London store, Liberty Style) or "Floreale"; in Spain "Modernista", in Austria "Sezessionstil" and, paradoxically, in France the English term "Modern Style" was often used, emphasizing the English origins of the movement."In design Art Nouveau was characterized by writhing plant forms and an opposition to the historicism which had plagued the 19th century. There was a tension implicit throughout the movement between the decorative and the modern which can be seen in the work of individual designers as well as in the chronology of the whole. Its emphasis on decoration and artistic unity links the movement to contemporary Symbolist ideas in art, as seen in the work of the Vienna Secessionists, but the movement was also associated with Arts and Crafts ideas and, as such, Art Nouveau forms a bridge between Morris and Gropius (recognized by Pevsner in his book, Pioneers of the Modern Movement, 1936)."In Britain the style was exemplified by the architecture of Rennie Mackintosh, and the design work of the Macdonald sisters. The lingering impact of Morris in England slowed down the progress of the new style in design although Mackmurdo, Godwin, Townsend and even Voysey were influenced towards Art Nouveau. It was in illustration that the ideas were most keenly felt, through the new periodicals and presses - the Yellow Book, the Studio, the Savoy, the Hobby Horse - and though the work of Beardsley, Ricketts and Selwyn Image."In France, despite Guimard"s famous glass and iron Metro designs, the movement was best expressed in the applied arts, especially the glassware of Lalique (1860-1945) and Galle (1846-1904). In Belgium, the style was promoted through the Societe des Vingts (Les Vingt) established in 1884, and including Ensor as well as the more characteristically Art Nouveau architects Horta and Van de Velde in its members. In Spain the style was concentrated in the eccentric hands of Gaudi in Barcelona. In Vienna, architects like Wagner, Hoffmann and Olbrich, and artists such as Klimt gathered to promote the style through the Secessionist magazine Ver Sacrum. In Germany, the movement split between the decorative tendencies of Otto Eckman (1865-1902) and the Pan magazine, and the streamlined design of Behrens. In America architects like Sullivan and Wright were influenced by European ideas but conceived Art Nouveau in different terms, whilst designers like Tiffany enthusiastically embraced the movement.

Technology can make our life better演讲稿200字左右

Technology is so crucial to society that people rarely stop to think that, on its own, it doesn"t accomplish much. Integrating technology into everyday life is what makes it indispensable.When organisations tackle that kind of hard work, unexpected consequences can follow. They can have a broader impact on the world than they ever anticipated. Who, for example, would imagine that the first airline reservation system, developed in the 1960s for American Airlines, would pave the way for online banking and e-retailing transactions?Innovative organisations are thoughtful and imaginative about how to make the most of technology. These businesses, governments, and communities don"t just install new technology in their factories or employees" offices and expect it to be transformative. They rethink their operations and redesign the flow of work. Organisations reshape business models. They consider what it would take for a new device or service to make our lives more efficient, or productive, or fulfilling.This is how progress happens. IBM is celebrating its 100th anniversary, which provides a chance to delve into the past and gain a new understanding of how progress happens. One insight gained over the past 100 years is this: Successful organisations use a systematic process of thinking when they deploy technology to transform what they do. Here are some of the approaches that push progress forward:Connect the Data: Society relies on data. Companies organise themselves around it to beat out competitors. New business models spring from it. Communities use it to dramatically improve quality of life. All this data collection is powered by a dizzying array of sophisticated technologies: sensors, GPS, the magnetic stripes on credit cards, even MRIs.Yet, too often, this information is siloed off. It"s not available to the people who need it. It"s not combined with other data. It"s not digitised. The progress is breathtaking when institutions in society connect data together and open it up for use by a wider group of employees, customers and partners.Innovate through Analytics: As the world becomes more complex and interconnected, keeping track of events -- let alone making sense and acting on them -- becomes more difficult. Yet, paradoxically, the leading organisations are the ones tackling ever more complex challenges. They are leading the way in improving the lives of their employees, citizens and customers.These companies and governments are much more sophisticated and bold in how they use everything from analytics and supercomputers to search-engine technology. Rather than simply deploying analytical tools to cut costs and be more efficient, they use them to manage rapid response in day-to-day operations, run simulations of potentially paralysing problems and then suggest solutions to them. This seeds ideas for innovative new products and services.For example, the oceans and seas around the world face pressing challenges, including pollution, overfishing and climate change. In response, Marine Institute Ireland peppered Galway Bay with sensors connected in real-time to data-crunching analytics. The idea? Pioneer a new way of monitoring vast water resources, replacing manual data gathering with automated systems and monitoring the bay like the living organism that it is. That ensures a quickerresponses to critical issues, such as detecting pollution or alerting ships and citizens to dangerous wave patterns.Communicate: Developing a new idea or product in secret or based upon focus groups no longer guarantees success. Innovation happens so quickly, people share so much information with each other so easily, the best way to meet their expectations is through communication and open iteration. That means using pilots, continual adaptation and social media to reach out to consumers and business partners.It"s one thing to tell employees or citizens that a project or a product is good for them. It"s another to spur buy-in and innovation by involving these people in the creative process, acting on their feedback and suggestions and keeping them up to date about the problems and successes the project is having.When officials in Malta wanted to install smarter, more efficient water and electricity meters island-wide, they didn"t just set about rolling out 250,000 new devices. Instead, they started with pilots, beginning with 200 people, but eventually expanding to 10,000. By including the citizens in the development of the project, the project leaders kept the whole community informed. Now Malta has the community"s confidence.Technology can be innovative. But technology alone can"t improve our lives. Only we humans have the brains and creativity to do that. When we start thinking systematically about where technology fits in and what we need to change about an organisation or an approach to get the most out it, that"s when we leap ahead. That"s when we make progress. And we all benefit.

求一篇英语演讲稿,题为what can Ido for the world? 时间为3分钟

What we can do for the world?I often have such doubt, but at the same time in the heart told myself: to mind your own business, the world in the end what will become of no relationship with me.Yes, isn"t it? Although we are a part of this world, but the lack of one of our people and a person, the earth itself will not stop?Yesterday saw "Tower of Babel", very depressed a movie, the director used many seemingly separate storyboard a convoluted and confusing film. After seeing the film and seen its comments are almost a guess from the name of the movie and the start of the director and the writer want to express the meaning of communication, communication, understanding...... The world is so big, but no one willing to calm down and listen to my plea to listen to my talk, I want to tell you is you want to tell me.Of course, we all just speculation to the opinions of others, even for their own ideas sometimes do not understand the extreme, perhaps such as a movie to express human thoughts and feelings of the medium itself was used to initiate, will always exists in our side of the problem in the face up, some are we explore the question for a long time, but some are we tried to hide the scars do not touch. But no matter what kind of emotion, whether these are similar to review things can forget after you shut down your computer now?Touch our inmost soul, the so-called human thing boils down to whether the practice is similar to like me in the blog writing articles to express his own weakness and a sense of loss?What can we do for the world?Once again see the living conditions of Chinese social stratum at the bottom of the people in the online postings, my mood besides the heavy but also very complex...... This year also catch up with the South snowstorm, again showing "the human nature" has come, like the Indonesia tsunami, we Chinese people"s sympathy always than any other country in the world to much, is because most population cause? But in this case, thinking of deep layer of what we call the real human nature does not because it shows us more as a "giver" vanity can in some extent?Don"t escape from this idea, a weak knees or even stretched in front of you, what is a bent your hand movements exactly represent? How many people are from the heart want to own warmth to others, and not because of the shallow pity and sympathy or is a from the moment of sadness? More paradoxically so much about war, about crime, may not need to say so distant and grand, single from the side of things, we sometimes for their family, their friends, the people who hurt their loved ones for...... Have said that some even superficial "pity and sympathy"?Perhaps the real human nature is our extremely reluctant to admit "selfish".Shows like "Babel" in that way, in a strange and fear in a foreign land, in addition to communication barriers in huge and psychological barriers, each person itself has shown selfish in that special environment to be enlarged. Here, I think God is not because human delusion and he built the tower of Babel and communicate with the language barrier barrier of human beings, but because the man thinks this self righteous and God built the tower of Babel can communicate ideas to punish human beings.In the film American couples because marriage problem itself faces and came to Morocco to look for solutions to their answers, it is precisely because of this, it leads to the later Mexico nanny because want to attend his son"s wedding, but the couple to take care of the children unattended had to go to Mexico together with the dilemma; by the police in the back of the border on questioning led to her nephew for some extreme psychological uneasiness was abandon them in Mexico desolate desert......

When the couple because had to rescue in the vicinity of the village, the other passengers including the couple itself leads to a nameless fear because of strangeness in different places, always in the international arena dominated the Americans showed rare timid.

How does fashion shape social identities? 英语作文1200单词 急!!!谢谢

Social thinkers have long treated fashion as a window upon social class and social change. Cultural theorists have focused on fashion to reflect on symbolic meaning and social ideals.5 Fashion has also been seen to embody representative characteristics of modernity, and even of culture itself.6Indeed, it is hard to imagine a locus of social life-whether in the arts, the sciences, politics, academia, entertainment, business, or even law or morality-that does not exhibit fashion in some way.7 People flock to ideas, styles, methods, and practices that seem new and exciting, and then eventually the intensity of that collective fascination subsides, when the newer and hence more exciting emerge on the scene. Participants of social practices that value innovation are driven to partake of what is "original," "cutting edge," "fresh," "leading," or "hot." But with time, those qualities are attributed to others, and another trend takes shape. This is fashion. The desire to be "in fashion"-most visibly manifested in the practice of dress-captures a significant aspect of social life, characterized by both the pull of continuity with others and the push of innovation toward the new.In the legal realm, this social dynamic of innovation and continuity is most directly engaged by the law of intellectual property. At this moment, fashion itself has the attention of federal policymakers, as Congress considers whether to provide copyright protection for fashion design,8 a debate that is sure to continue in the face of fashion designers" many complaints of harm by design copyists.9 Despite being the core of fashion and legally protected in Europe, fashion design lacks protection against copying under U.S. intellectual property law.10 Thus it has seemed sensible to posit that fashion design is relevantly different from literature, music, and art, where legal protection from copying is thought to be necessary to provide producers an incentive to create.11 Indeed, some commentators even suggest that perhaps fashion design is so different from other arts that its vitality, or even survival, paradoxically depends on the existence of the opposite kind of regime-a culture of tolerated rampant copying.

随着大数据集群的使用,大数据的安全受到越来越多的关注一个安全的大数据集群的使用,运维必普通的集群更为复杂。 集群的安全通常基于kerberos集群完成安全认证。kerberos基本原理可参考 :一张图了解Kerberos访问流程 Spark应用(On Yarn模式下)在安全的hadoop集群下的访问,需要访问各种各样的组件/进程,如ResourceManager,NodeManager,NameNode,DataNode,Kafka,Hmaster,HregionServer,MetaStore等等。尤其是在长时运行的应用,如sparkStreaming,StructedStreaming,如何保证用户认证后的长期有效性,其安全/认证更为复杂。 一个Spark应用提交用户要先在kdc中完成用户的认证,及拿到对应service服务的票据之后才能访问对应的服务。由于Spark应用运行时涉及yarnclient,driver,applicationMaster,executor等多个服务,这其中每个进程都应当是同一个用户启动并运行,这就涉及到多个进程中使用同一个用户的票据来对各种服务进行访问,本文基于Spark2.3对此做简要分析。 spark应用的提交用户认证之后才能提交应用,所以在yarnclient/driver的逻辑中必然会执行到kerberos认证相关的登录认证。然而其他的进程如applicationMaster,executor等均需要经过认证,应用提交后才由用户启动,这些进程则可以不进行kerberos认证而是利用Hadoop的token机制完成认证,减小kerberos服务压力,同时提高访问效率。 Hadoop的token实现基类为org.apache.hadoop.security.token.Token, 不同的服务也可hadoop的token来交互,只要使用不同的identifer来区分token即可。 如NMTokenIdentifier, AMRMTokenIdentifier,AuthenticationTokenIdentifier等不同的tokenIdentifier来区分不同的服务类型的token。 此处yarnclient指的是向ResourceManager提交yarn应用的客户端。在spark中,向yarn提交应用有两种应用有yarn-client,yarn-cluster模式。在这两种应用模式下提交应用,yarn client逻辑有些许不同。 安全hadoop场景下spark的用户登录认证机制 在client的submitApplication方法中提交app,之后创建amContext,准备本地资源,此时会将本地的文件上传至HDFS,其中就包括keytab文件,同时会生成 spark_conf .properties配置文件以供am使用,该配置文件中会包含keytab的配置 其中的amKeytabFileName是在setUpCredentials时设置如下,该值为指定的keytab文件加上随机的字符串后缀,骑在am重点使用,可参考下节的介绍。 获取相关组件的token,注意:此处的token均非与yarn服务交互相关token,这里只有与HDFS,HBASE,Hive服务交互的token。 } Spark中常访问的服务使用token机制的有hive,hbase,hdfs,对应的tokenProvider如下: 以HbaseDelegationTokenProvider为例,主要是通过反射调用hbase的TokenUtil类的obtainTOken方法,对应的obtainDelegationTokens方法如下: PS : HBase的token获取的用户需要具有hbase:meta表的exec权限,否则无法成功获取token 在获取token后,将token设置到amContainer中,并放入appContext中 在yarn-client模式下,driver在yarnclient进程中启动,同样需要访问业务层及集群的相关组件如hdfs。driver通过读取am更新在hdfs路径下的credentials文件来保证driver节点的token有效。 在yarn-cluster模式下,driver运行在applicationMaster的JVM中,其安全相关由Am同一操作 applicationMaster是Yarn进行应用调度/管理的核心,需要与RM/NM等进行交互以便应用运行。其中相关的交互均通过token完成认证,认证实现由Yarn内部框架完成。查看am日志发现,即是在非安全(非kerberos)的场景下,同样会使用到token。而与hdfs,hbase等服务交互使用的token则需Spark框架来实现。 在ResourceManager接收到应用提交的ApplicationSubmissionContext后,在其AmLauncher.java的run方法中为am设置生成“YARN_AM_RM_TOKEN,该token用于am于rm通信使用” Am在启动之后,会向ResourceManager申请container,并与对应的NodeManager通信以启动container。然而AM与NM通信的token是如何得到的呢? 查看AMRMClientImpl类可以看到,AM向RM发送分配请求,RM接收到请求后,将container要分配至的NM节点的Token放置response中返回给AM。Am接收到response后,会保存NMToken,并判定是否需要更新YARN_AM_RM_TOKEN RM通过ApplicationMasterService响应allocation请求 AM在准备启动container时,将当前用户的token都设置进ContainerLaunchContext中 查看Am启动命令大致如下,可以发现有指定配置文件,而该配置文件即为yarnclient生成上传至hdfs,在am启动前由NodeManager从hdfs中copy至本地路径,供container使用: 查看此配置文件可以看到有如下配置项: 下图为am进程使用到的资源文件 如上可以看出,am虽然运行在集群中,但运行时认证相关的资源已经准备就绪。下面分析其运行中关于安全的逻辑 在applicationMaster中,定期更新token,并写入文件到hdfs的相关目录,并清理旧文件以供各executor使用。 在ApplicationMaster启动后,进行login登录并启动名为am-kerberos-renewer的dameon线程定期登录,保证用户认证的有效性 private val ugi = { val original = UserGroupInformation.getCurrentUser() 在am中启动AMCredentialRenewerStarter线程,调度认证登录及token renew逻辑 在scheduleLoginFromKeytab中,会周期调度登录,token获取更新写入hdfs文件等操作。 其核心逻辑如下 调度周期: 调度流程: executor的认证同样使用的是token机制。executor启动之后,根据driver启动设置的${spark.yarn.credentials.file}启动token更新: Executor中的token更新是读取hdfs目录 {timeStamp}-${nextSuffix}目录下的文件,读取到缓存中,以便保证读取到的是更新后的token使用。 Spark框架完成的kerberos认证及使用token与其他服务交互的机制使用较为简单,只需要在提交应用时的spark-submit命令行中加入--principal appuserName --keytab /path/to/user.keytab即可

苹果双重认证要不要开

iphone双重认证要开吗 双重认证是为 Apple ID 提供的一层额外安全保护,旨在确保只有您可以访问自己的帐户,即使其他人知道您的密码也是如此。 如何开启Apple ID的双重认证? 如果想要开启双重认证,那么设备的系统版本必须是 iOS 9 或者 OS X El Capitan 或更高版本的。 如何开启Apple ID的双重认证?开启双重认证之前,确认你的Apple ID账户和密码都记得。 开启双重认证的方式有两种: 第一种是在你的受信任设备上开启,也就是登陆此账号的手机。 第二种在电脑上登陆Apple ID账户管理页面,网页上开启。 如何开启Apple ID的双重认证? 苹果官网双重认证建议要不要开启 建议开启 双重认证简介: 双重认证可以理解为是在二步验证基础上加强的Apple ID的安全级别但这里特殊强调一点,无论是二步验证或是双重认证也仅仅是加强保护ID而已。 但我觉得开启还是有一定的保护作用,至少二步验证或双重认证,盗号者不能修改你当前ID密码,恶意锁住你的机器无非是想勒索你的钱财。这时马上采取紧急办法修改密码,在重新登陆iCloud就能解除锁定,如果当前手机号不能收到验证码,就使用备用手机号才找回(切记一定要保证开启两个以上的可信任手机号)。 双重认证开启后,在登陆iCloud会有提示当前登陆ID信息。 苹果官网双重认证建议要不要开启 建议开启 双重认证简介: 1. 双重认证可以理解为是在二步验证基础上加强的Apple ID的安全级别 2. 但这里特殊强调一点,无论是二步验证或是双重认证也仅仅是加强保护ID而已。 3. 但我觉得开启还是有一定的保护作用,至少二步验证或双重认证,盗号者不能修改你当前ID密码,恶意锁住你的机器无非是想勒索你的钱财。 4. 这时马上采取紧急办法修改密码,在重新登陆iCloud就能解除锁定,如果当前手机号不能收到验证码,就使用备用手机号才找回(切记一定要保证开启两个以上的可信任手机号)。 5. 双重认证开启后,在登陆iCloud会有提示当前登陆ID信息。 苹果ID用了双重认证是不是就不用安全问题了 是的。 有了双重认证,只能通过您信任的设备(如 iPhone、iPad 或 Mac)才能访问您的帐户。首次登录一部新设备时,您需要提供两种信息:您的密码和自动显示在您的受信任设备上的六位验证码。 输入验证码后,您即确认您信任这部新设备。例如,如果您有一部 iPhone 并且要在新购的 Mac 上首次登录您的帐户,您将收到提示信息,要求您输入密码和自动显示在您 iPhone 上的验证码。 由于只输入密码不再能够访问您的帐户,因此双重认证显著增强了 Apple ID 以及所有通过 Apple 储存的个人信息的安全性。 登录后,系统将不会再次要求您在该设备上输入验证码,除非您完全退出登录帐户、抹掉设备数据或出于安全原因而需要更改密码。 当您在 Web 上登录时,可以选择信任您的浏览器,这样当您下次从该电脑登录时,系统就不会要求您输入验证码。 1.进入Apple ID管理员后,按下「管理你的Apple ID」,没有帐号就建立一个吧。 2. 登入你的Apple ID帐号 3. 先按一下左手边的「密码与帐号安全」,然后右手边填入你申请Apple ID时所输入的答案。如果已忘了的话就要求将答案传送至你的Email地址吧。 4. 通过第一关的安全提示问题后,就会见到双步骤验证的设定,按下「开始设定」 5. 了解一下使用方法,就是使用帐号和密码登入后,还需要通过你注册的设备接收验证码,这样才能正式登入Apple ID帐号。没问题的话,就继续。 6. 接下来的还是一些需要你清楚和记注的事项,大家可以先看一看 7. 最后,你还必须等待3天才可以开启这个验证机制。原因是,Apple担心你的帐号已经被盗,做这次设定的并非阁下你本人,所以需要3天后确定没有其他人偷用你的帐号后,就可以开始完成设定。 Apple会发送电邮给你作确定,大家3天后再跟指示做即可。 apple id要开双重认证吗 第一步:首先进入苹果中国官网,然后在上部导航条中,点击进入“技术支持”,之后在点击进入“管理您的Apple ID” 第二步:接下来会进入Apple ID登陆界面,然后输入自己的Apple ID账号和密码进行登陆 第三步:登陆成功后,在左侧点击进入“密码和账户安全”然后在右侧填写上曾经设置过的安全提示问题,完成后,点击下方的“继续” 第四步:之后就可以进入Apple ID“两步验证”设置入口了,在两步验证下方,点击“开始设置” 第五步:接下来会看到Apple ID两步验证设置的一些操作提示,直接点击下方的“继续” 第六步:接下来同样是提示部分,大意是开启了Apple ID两步验证后,此前的安全问题会自动失效,另外账户安全性也会提升。这里依旧点击下方的“继续”。接下来还是相关的重要提示,主要告诉您开启两步验证后,如果今后忘记Apple ID密码,您将需呀恢复密钥和受新人设备来重置密码,这里依旧不用理会,直接点击下方的“开始” 第七步:接下来终于是正式的设置了,首先需要选择国家和地区,然后填写上您的手机号码,完成后点击“下一步” 第八步:接下来苹果网站会向比此前填写的手机号上发送一个验证码,将接受到的验证法填写到验证框中,完成后点击下方的“验证” 第九步:验证通过后会显示该帐号所关联的设备,如果没有错误,则点击下方的“继续”。接下来会显示“恢复密钥”,这一段字符串需要你安全备份保存,这个恢复密钥很重要,因为一旦后期忘记Apple ID密码,找回的时候必须用到这个密钥,因此建议大家备份保存到电脑或者上传的网盘中,以便后用。完成后,依旧是点击下方的“继续” 第十步:最后一步就是在接下来的页面中,输入刚才上面笔者要求大家备份的“恢复密钥”进行验证,确认后会显示提醒说明,点击“了解并启用验证”便完成了Apple ID两步验证设置了。 为什么我的苹果id不能开双重认证 一、谁可以开启双重认证看1如果 iCloud 用户拥有至少一部装有 iOS 9 或 OS X El Capitan 或更高版本的设备,现在便可使用双重认证。 以下是与 Apple ID 搭配使用的所有设备适用的最低建议系统要求:装有 iOS 9 的 iPhone、iPad 或 iPod touch装有 OS X El Capitan 和 iTunes 12.3 的 Mac装有 watchOS 2 的 Apple Watch装有 tvOS 的 Apple TV(第 4 代)装有 Windows 版 iCloud 5 和 iTunes 12.3.3 的 Windows PC另外还建议您在帐户中登记一张有效的。如果您忘记了密码,系统可能会要求您提供此信息以帮助验证您的身份。 请注意,尽管绝大多数 iCloud 用户现在可以开启双重认证,但是根据 Apple 的判断,某些帐户类型可能仍然没有资格开启此功能。END二、开启双重认证有两种方式1在新设备上设置如果您正在设置新设备和双重认证,并且满足所有建议的系统要求,则在使用设置助理过程中,登录后您可能会看到以下屏幕。 要继续操作,请轻点逗继续地并输入可在登录新设备时用于接收验证码的电话号码。验证此电话号码后,双重认证将会自动开启。 2在已在使用的设备上设置如果您设置的不是新设备,请确保您的 iOS 设备上装有 iOS 9 或更高版本,或 Mac 上装有 OS X El Capitan 或更高版本,并按照以下步骤开启双重认证。在 iPhone、iPad 或 iPod touch 上:前往逗设置地>逗iCloud地>,然后轻点您的 Apple ID。 轻点逗安全性地。在屏幕底部,查找显示逗打开双重认证地的按钮。 在 Mac 上:前往苹果 (uf8ff) 菜单 >逗系统偏好设置地>逗iCloud地>逗帐户详细信息地。点按逗安全性地。 在屏幕底部,查找显示逗打开双重认证地的按钮。如果与您 Apple ID 搭配使用的所有设备并未全部满足建议的系统要求,或者如果您没有登记有效的,您将收到相关警告信息。 继续操作前请先阅读该信息,并考虑更新设备或将信息添加到您的帐户中,以确保在登录或重设密码时可以获得最佳体验。END三、使用双重认证时的注意事项1双重认证会显著提升 Apple ID 的安全性。 开启双重认证后,您需要使用密码并访问受信任设备或受信任的电话号码才能登录您的帐户。为了尽可能保护帐户的安全性并确保您永远不会失去访问权限,您应遵循以下几条简单准则:牢记 Apple ID 密码。 在您的所有设备上均使用一个设备密码。确保受信任的电话号码始终为最新号码。 确保受信任设备的安全。END四、如果我忘记了密码该怎么办看1您可以按照以下步骤,通过受信任的 iPhone、iPad 或 iPod touch 来重设或更改密码:前往逗设置地>逗iCloud地。 轻点您的名称。轻点逗密码与安全性地。 轻点逗更改密码地。输入新密码。 上述步骤只能在已启用设备密码的受信任设备上执行。如果您无法访问受信任设备,请前往iforgot.apple//password/verify/appleid,输入您的 Apple ID,然后按照提示操作来重设密码。 如果需要帮助,请尝试以下步骤。END五、如果我无法访问受信任设备或者未收到验证码,该怎么办看1如果您要登录,但是手边没有可显示验证码的受信任设备,您可以选择以短信或电话方式将验证码发送至受信任的电话号码。 点按登录屏幕上的逗没有收到验证码吗地,然后选择将验证码发送至受信任的电话号码。您还可以直接从受信任设备的逗设置地中获取验证码。 苹果手机开启了双重认证,未信任的设备之前登入了,开启了双重认证 首先需要明确的一个概念:「双重认证」不是「两步验证」。 「双重认证」与「两步验证」的区别尽管两种验证方式大致原理相同,它们在具体的实现方式上仍然有着显著的差异。1. 开通途径 「两步验证」只能在 Apple ID 的管理页面开通。 「双重认证」则只能在 iOS 9.3 或 OS X 10.11.4 的 iCloud 账户管理页面中开通。2. 设备注册方式 在开通「两步验证」时,系统将会要求你单独发送验证码到每台开启了「查找我的 iPhone」的 iOS 设备上,才能将对应设备设为「受信任设备」,并使用它们来接收验证码。 在开通「双重认证」时,系统会自动将所有登录了iCloud 的设备设为「受信任设备」。这两种方式都要求手动验证「受信任电话号码」。 3. 恢复密钥 「两步验证」会生成一串「恢复密钥」作为恢复账户访问权限的后备手段。 「双重认证」不会生成任何恢复密钥。 4. 验证过程 在未受信任的设备或浏览器上登录Apple ID 时,两种验证方式都会要求输入额外的验证码确认身份。 输入账户密码后,「两步验证」会要求你选择一台「受信任设备」或者「受信任电话号码」接收一串四位数的验证码。 「双重认证」则会自动向所有的「受信任设备」发送登录提醒,你也可以手动选择使用手机号码来接收验证码。与「两步验证」不同的是,登录提醒不仅仅包含验证码,还会显示账号登录的大致地理位置,验证码的长度也从四位延长到了六位。 用户可以在任一设备上选择是否允许此次登录尝试,选择「允许」系统将会自动展示六位数验证码,「不允许」则会直接拒绝此次登录。在一台设备上选择后,其他设备上的登录提醒将会自动消失。 5.接收验证码的设备「两步验证」只能向 iOS 设备发送验证码。 「双重认证」既可以向 iOS 设备发送验证码,也可以发送给 Mac。 6. 离线状态下的使用 在所有「受信任设备」和「受信任电话号码」离线时,「两步验证」将无法使用,这可能会给你的登录带来麻烦。 而「双重认证」可以在「受信任设备」上离线生成验证码,大大简化了用户体验。 如果要在安装 iOS 9 和 OS X El Capitan 之前版本的设备上登录 Apple ID,你需要手动生成验证码,并在旧款设备的密码栏内输入账户密码,后跟六位生成的验证码。7. 安全信息的更改 开通了「两步验证」,你只能在Apple ID内修改包括「受信任设备」在内的安全信息。 「双重认证」则可以让你在设备端的账号管理页面直接修改。8. 忘记密码后的处理 「两步验证」要求你拥有账户密码、恢复密钥、一台可接收验证码的「受信任设备」中的任意两样才能访问 Apple ID。 一旦丢失这三样中的任意两样,你将永久性失去 Apple ID 的访问权限。 「双重认证」没有恢复密钥。 在你忘记密码,也不能使用「受信任设备」和「受信任电话号码」时,你还可以使用「账户恢复」并提交有关信息给苹果进行审核,尝试重新获得账户的访问权限。苹果技术支持无权干涉「账户恢复」的流程,一定程度上杜绝了「内鬼」作崇。 iphone双重认证能不能解开 在苹果官网开启设置双重认证一直失败是怎么回事?想要保护你的苹果设备apple id,去官方开启双重认证但是一直被失败闹心的用户,可以先来了解一些你是否满足开启条件。 双重认证为什么设置失败 1.装有 iOS 9 的 iPhone、iPad 或 iPod touch 2.装有 OS X El Capitan 和 iTunes 12.3 的 Mac 3.装有 watchOS 2 的 Apple Watch 4.装有 tvOS 的 Apple TV(第 4 代) 5装有 iCloud(Windows 版)v.5 和 iTunes 12.3 的 Windows P 6.我们还将通过其他条件来确定是否开放双重认证。因此,即使您的设备符合所有系统要求,可能也无法立即获得双重认证。 我们将逐渐推广,直到可以向所有用户提供此功能。 7.Apple 生态系统中有亿万用户使用各种设备和软件版本,因此需要耗费一些时间。 为了确保最佳体验,我们将从今年秋季开始逐渐推广双重认证。

Spark通信框架Spark Network Common

一直以来,基于Akka实现的RPC通信框架是Spark引以为豪的主要特性,也是与Hadoop等分布式计算框架对比过程中一大亮点,但是时代和技术都在演化,从Spark1.3.1版本开始, 为了解决大块数据(如Shuffle)的传输问题 ,Spark引入了Netty通信框架,到了1.6.0版本,Netty完全取代了Akka,承担Spark内部所有的RPC通信以及数据流传输。 JAVA IO也经历了几次演化,从最早的BIO(阻塞式/非阻塞IO),到1.4版本的NIO(IO复用),到1.7版本的NIO2.0/AIO(异步IO)。 基于早期BIO来实现高并发网络服务器都是依赖多线程来实现,但是线程开销较大,BIO的瓶颈明显,NIO的出现解决了这一大难题, 基于IO复用解决了IO高并发 。 但是NIO有也有几个缺点: 因为这几个原因,促使了很多JAVA-IO通信框架的出现,Netty就是其中一员,它也因为高度的稳定性,功能性,性能等特性,成为Java开发的首选 首先是NIO的上层封装,Netty提供了NioEventLoopGroup / NioSocketChannel / NioServerSocketChannel的组合来完成实际IO操作,继而在此之上实现数据流Pipeline以及EventLoop线程池等功能。 另外它又重写了NIO,JDK-NIO底层是基于Epoll的LT模式来实现,而Netty是基于Epoll的ET模式实现的一组IO操作EpollEventLoopGroup / EpollSocketChannel / EpollServerSocketChannel Netty对两种实现进行完美的封装,可以根据业务的需求来选择不同的实现 从Akka出现背景来说,它是基于Actor的RPC通信系统,它的核心概念也是Message,它是基于协程的,性能不容置疑;基于scala的偏函数,易用性也没有话说,但是它毕竟只是RPC通信,无法适用大的package/stream的数据传输,这也是Spark早期引入Netty的原因。 首先不容置疑的是Akka可以做到的,Netty也可以做到,但是Netty可以做到,Akka却无法做到。原因是啥?在软件栈中,Akka相比Netty要Higher一点,它专门针对RPC做了很多事情,而Netty相比更加基础一点, 可以为不同的应用层通信协议(RPC,FTP,HTTP等)提供支持 ,在早期的Akka版本,底层的NIO通信就是用的Netty。 其次一个优雅的工程师是不会允许一个系统中容纳两套通信框架!最后,虽然Netty没有Akka协程级的性能优势,但是Netty内部高效的Reactor线程模型,无锁化的串行设计,高效的序列化,零拷贝,内存池等特性也保证了Netty不会存在性能问题。 那么Spark是怎么用Netty来取代Akka呢?一句话,利用偏函数的特性,基于Netty“仿造”出一个简约版本的Actor模型。 对于Network通信,不管传输的是序列化后的对象还是文件,在网络上表现的都是字节流。在传统IO中,字节流表示为Stream;在NIO中,字节流表示为ByteBuffer;在Netty中字节流表示为ByteBuff或FileRegion;在Spark中,针对Byte也做了一层包装,支持对Byte和文件流进行处理,即ManagedBuffer; ManagedBuffer包含了三个函数createInputStream(),nioByteBuffer(),convertToNetty()来对Buffer进行“类型转换”,分别获取stream,ByteBuffer,ByteBuff或FileRegion;NioManagedBuffer / NettyManagedBuffer / FileSegmentManagedBuffer也是针对性提供了具体的实现。 更好的理解ManagedBuffer :比如Shuffle BlockManager模块需要在内存中维护本地executor生成的shuffle-map输出的文件引用,从而可以提供给shuffleFetch进行远程读取,此时文件表示为FileSegmentManagedBuffer,shuffleFetch远程调用FileSegmentManagedBuffer.nioByteBuffer / createInputStream函数从文件中读取为Bytes,并进行后面的网络传输。如果已经在内存中bytes就更好理解了,比如将一个字符数组表示为NettyManagedBuffer。 协议是应用层通信的基础,它提供了应用层通信的数据表示,以及编码和解码的能力。在Spark Network Common中,继承AKKA中的定义,将协议命名为Message,它继承Encodable,提供了encode的能力。 Message根据请求响应可以划分为RequestMessage和ResponseMessage两种;对于Response,根据处理结果,可以划分为Failure和Success两种类型;根据功能的不同,主要划分为Stream,ChunkFetch,Rpc。 Server构建在Netty之上,它提供两种模型NIO和Epoll,可以通过参数(spark.[module].io.mode)进行配置,最基础的module就是shuffle,不同的IOMode选型,对应了Netty底层不同的实现,Server的Init过程中,最重要的步骤就是根据不同的IOModel完成EventLoop和Pipeline的构造 其中,MessageEncoder/Decoder针对网络包到Message的编码和解码,而最为核心就TransportRequestHandler,它封装了对所有请求/响应的处理; TransportChannelHandler内部实现也很简单,它封装了responseHandler和requestHandler,当从Netty中读取一条Message以后,根据判断路由给相应的responseHandler和requestHandler。 Sever提供的RPC,ChunkFecth,Stream的功能都是依赖TransportRequestHandler来实现的;从原理上来说,RPC与ChunkFecth / Stream还是有很大不同的,其中RPC对于TransportRequestHandler来说是功能依赖,而ChunkFecth / Stream对于TransportRequestHandler来说只是数据依赖。 怎么理解?即TransportRequestHandler已经提供了ChunkFecth / Stream的实现,只需要在构造的时候,向TransportRequestHandler提供一个streamManager,告诉RequestHandler从哪里可以读取到Chunk或者Stream。而RPC需要向TransportRequestHandler注册一个rpcHandler,针对每个RPC接口进行功能实现,同时RPC与ChunkFecth / Stream都会有同一个streamManager的依赖,因此注入到TransportRequestHandler中的streamManager也是依赖rpcHandler来实现,即rpcHandler中提供了RPC功能实现和streamManager的数据依赖。 Server是通过监听一个端口,注入rpcHandler和streamManager从而对外提供RPC,ChunkFecth,Stream的服务,而Client即为一个客户端类,通过该类,可以将一个streamId / chunkIndex对应的ChunkFetch请求,streamId对应的Stream请求,以及一个RPC数据包对应的RPC请求发送到服务端,并监听和处理来自服务端的响应;其中最重要的两个类即为TransportClient和TransportResponseHandler分别为上述的“客户端类”和“监听和处理来自服务端的响应"。 那么TransportClient和TransportResponseHandler是怎么配合一起完成Client的工作呢? 由TransportClient将用户的RPC,ChunkFecth,Stream的请求进行打包并发送到Server端,同时将用户提供的回调函数注册到TransportResponseHandler,TransportResponseHandler是TransportChannelHandler的一部分,在TransportChannelHandler接收到数据包,并判断为响应包以后,将包数据路由到TransportResponseHandler中,在TransportResponseHandler中通过注册的回调函数,将响应包的数据返回给客户端 无论是BlockTransfer还是ShuffleFetch都需要跨executor的数据传输,在每一个executor里面都需要运行一个Server线程(后面也会分析到,对于Shuffle也可能是一个独立的ShuffleServer进程存在)来提供对Block数据的远程读写服务 在每个Executor里面,都有一个BlockManager模块,它提供了对当前Executor所有的Block的“本地管理”,并对进程内其他模块暴露getBlockData(blockId: BlockId): ManagedBuffer的Block读取接口,但是这里GetBlockData仅仅是提供本地的管理功能,对于跨远程的Block传输,则由NettyBlockTransferService提供服务。 NettyBlockTransferService本身即是Server,为其他其他远程Executor提供Block的读取功能,同时它即为Client,为本地其他模块暴露fetchBlocks的接口,支持通过host/port拉取任何Executor上的一组的Blocks。 源码位置 spark-core: org.apache.spark.network.netty NettyBlockTransferService作为一个Server,与Executor或Driver里面其他的服务一样,在进程启动时,由SparkEnv初始化构造并启动服务,在整个运行时的一部分。 一个Server的构造依赖RpcHandler提供RPC的功能注入以及提供streamManager的数据注入。对于NettyBlockTransferService,该RpcHandler即为NettyBlockRpcServer,在构造的过程中,需要与本地的BlockManager进行管理,从而支持对外提供本地BlockMananger中管理的数据 RpcHandler提供RPC的功能注入 在这里还是属于比较“简陋的”,毕竟他是属于数据传输模块,Server中提供的chunkFetch和stream已经足够满足他的功能需要,那现在问题就是怎么从streamManager中读取数据来提供给chunkFetch和stream进行使用呢? 就是NettyBlockRpcServer作为RpcHandler提供的一个Rpc接口之一:OpenBlocks,它接受由Client提供一个Blockids列表,Server根据该BlockIds从BlockManager获取到相应的数据并注册到streamManager中,同时返回一个StreamID,后续Client即可以使用该StreamID发起ChunkFetch的操作。 从NettyBlockTransferService作为一个Server,我们基本可以推测NettyBlockTransferService作为一个Client支持fetchBlocks的功能的基本方法: 同时,为了提高服务端稳定性,针对fetchBlocks操作NettyBlockTransferService提供了非重试版本和重试版本的BlockFetcher,分别为OneForOneBlockFetcher和RetryingBlockFetcher,通过参数(spark.[module].io.maxRetries)进行配置,默认是重试3次 在Spark,Block有各种类型,可以是ShuffleBlock,也可以是BroadcastBlock等等,对于ShuffleBlock的Fetch,除了由Executor内部的NettyBlockTransferService提供服务以外,也可以由外部的ShuffleService来充当Server的功能,并由专门的ExternalShuffleClient来与其进行交互,从而获取到相应Block数据。功能的原理和实现,基本一致,但是问题来了, 为什么需要一个专门的ShuffleService服务呢? 主要原因还是为了做到任务隔离,即减轻因为fetch带来对Executor的压力,让其专心的进行数据的计算。 在目前Spark中,也提供了这样的一个AuxiliaryService:YarnShuffleService,但是对于Spark不是必须的,如果你考虑到需要“ 通过减轻因为fetch带来对Executor的压力 ”,那么就可以尝试尝试。 同时,如果启用了外部的ShuffleService,对于shuffleClient也不是使用上面的NettyBlockTransferService,而是专门的ExternalShuffleClient,功能逻辑基本一致! Akka的通信模型是基于Actor,一个Actor可以理解为一个Service服务对象,它可以针对相应的RPC请求进行处理,如下所示,定义了一个最为基本的Actor: Actor内部只有唯一一个变量(当然也可以理解为函数了),即Receive,它为一个偏函数,通过case语句可以针对Any信息可以进行相应的处理,这里Any消息在实际项目中就是消息包。 另外一个很重要的概念就是ActorSystem,它是一个Actor的容器,多个Actor可以通过name->Actor的注册到Actor中,在ActorSystem中可以根据请求不同将请求路由给相应的Actor。ActorSystem和一组Actor构成一个完整的Server端,此时客户端通过host:port与ActorSystem建立连接,通过指定name就可以相应的Actor进行通信,这里客户端就是ActorRef。所有Akka整个RPC通信系列是由Actor,ActorRef,ActorSystem组成。 Spark基于这个思想在上述的Network的基础上实现一套自己的RPC Actor模型,从而取代Akka。其中RpcEndpoint对应Actor,RpcEndpointRef对应ActorRef,RpcEnv即对应了ActorSystem。 RpcEndpoint与Actor一样,不同RPC Server可以根据业务需要指定相应receive/receiveAndReply的实现,在Spark内部现在有N多个这样的Actor,比如Executor就是一个Actor,它处理来自Driver的LaunchTask/KillTask等消息。 RpcEnv相对于ActorSystem: RpcEndpointRef即为与相应Endpoint通信的引用,它对外暴露了send/ask等接口,实现将一个Message发送到Endpoint中。 这就是新版本的RPC框架的基本功能,它的实现基本上与Akka无缝对接,业务的迁移的功能很小,目前基本上都全部迁移完了。 RpcEnv不仅从外部接口与Akka基本一致,在内部的实现上,也基本差不多,都是按照MailBox的设计思路来实现的; RpcEnv即充当着Server,同时也为Client内部实现。 当作为Server ,RpcEnv会初始化一个Server,并注册NettyRpcHandler。RpcHandler的receive接口负责对每一个请求进行处理,一般情况下,简单业务可以在RpcHandler直接完成请求的处理,但是考虑一个RpcEnv的Server上会挂载了很多个RpcEndpoint,每个RpcEndpoint的RPC请求频率不可控,因此需要对一定的分发机制和队列来维护这些请求,其中Dispatcher为分发器,InBox即为请求队列; 在将RpcEndpoint注册到RpcEnv过程中,也间接的将RpcEnv注册到Dispatcher分发器中,Dispatcher针对每个RpcEndpoint维护一个InBox,在Dispatcher维持一个线程池(线程池大小默认为系统可用的核数,当然也可以通过spark.rpc.netty.dispatcher.numThreads进行配置),线程针对每个InBox里面的请求进行处理。当然实际的处理过程是由RpcEndpoint来完成。 其次RpcEnv也完成Client的功能实现 ,RpcEndpointRef是以RpcEndpoint为单位,即如果一个进程需要和远程机器上N个RpcEndpoint服务进行通信,就对应N个RpcEndpointRef(后端的实际的网络连接是公用,这个是TransportClient内部提供了连接池来实现的),当调用一个RpcEndpointRef的ask/send等接口时候,会将把“消息内容+RpcEndpointRef+本地地址”一起打包为一个RequestMessage,交由RpcEnv进行发送。注意这里打包的消息里面包括RpcEndpointRef本身是很重要的,从而可以由Server端识别出这个消息对应的是哪一个RpcEndpoint。 和发送端一样,在RpcEnv中,针对每个remote端的host:port维护一个队列,即OutBox,RpcEnv的发送仅仅是把消息放入到相应的队列中,但是和发送端不一样的是:在OutBox中没有维护一个所谓的线程池来定时清理OutBox,而是通过一堆synchronized来实现的,add之后立刻消费。 摘自:Github/ColZer

已经把磁盘抹掉了,怎么用U盘装OS系统

步骤如下: 一、 准备工作: 1.准备一个 8GB 或以上容量的 U 盘,确保里面的数据已经妥善备份好(该过程会抹掉 U 盘全部数据) 2.在程序应用文件夹中有刚刚从官网下载下来的 “安装 OS X El Capitan” 二、格式化优盘(3.0优盘亲测可用) 1.插入你的 U 盘,然后在「应用程序」->「实用工具」里面找到并打开「磁盘工具」 2.在左方列表中找到 U 盘的名称并点击 3.右边顶部选择「分区」,然后在「分区布局」选择「1个分区」 4.在分区信息中的 「名称」输入「Capitan」 (由于后面的命令中会用到此名称,如果你要修改成其他(英文),请务必对应修改后面的命令) 5.在「格式」中选择 「Mac OS 扩展 (日志式)」 6.这时,先别急着点“应用”,还要先在 「选项」里面,选择「GUID 分区表」 7.开始格式化 三、输入终端命令开始制作启动盘 1.请再次确保名为 “安装 OS X El Capitan” 的文件是保存在「应用程序」的目录中 2.在「应用程序」->「实用工具」里面找到「终端」并打开。也可以直接通过 Spotlight 搜索「终端」打开 3.复制下面的命令,并粘贴到「终端」里,按回车运行: ——命令开始—— 从sudo开始复制(不要复制这句话) sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia –volume /Volumes/Capitan –applicationpath /Applications/Install OS X El Capitan.app –nointeraction ——命令结束—— 到nointeraction结束(不要复制这句话) 命令说明: Install OS X El Capitan.app 这个是正式版的“安装 OS X El Capitan” 正确位置 Capitan 这个是优盘的名字 回车后,系统会提示你输入管理员密码,接下来就是等待系统开始制作启动盘了。这时,命令执行中你会陆续看到类似以下的信息: Erasing Disk: 0%… 10%… 20%… 30%…100%… Copying installer files to disk… Copy complete. Making disk bootable… Copying boot files… Copy complete. Done. 当你看到最后有 「Copy complete」和「Done」 字样出现就是表示启动盘已经制作完成了! 四、U 盘启动安装 OS X El Capitan 的方法 当你插入制作完成的 OS X El Capitan U盘启动盘之后,桌面出现「Install OS X El Capitan」的盘符那么就表示启动盘是正常的了。那么怎样通过 USB 启动进行全新的系统安装呢? 其实很简单,先在目标电脑上插上 U 盘,然后重启你的 Mac,然后一直按住「option」(alt) 按键不放,直到屏幕显示多出一个 USB 启动盘的选项。 这时选择 U 盘的图标回车,即可通过 U 盘来安装 OS X El Capitan 了!这时,你可以直接覆盖安装系统(升级),也可以在磁盘工具里面格式化抹掉整个硬盘,或者重新分区等实现全新的干净的安装。

拼音字母表后面接什么?

后面接着是:b、p、m、f、d、t、n、l、g、k、h、j、q、x、z、c、s、zh、ch、sh、r、y、w。单韵母:a[阿]、o[哦]、e[鹅]、i[衣]、u[乌]、ü[迂]。复韵母:ai[哀]、ei[A]、ui[威]、ao[奥]、ou[欧]、iu[悠]、ie[耶]、üe[约]、er[儿]。前鼻韵母:an[安]、en[恩]、in[因]、un[温]、ün[晕]。后鼻韵母:ang[昂]、eng[鞥]、ing[英]、ong[轰的韵母]。整体认读音节:zhi[吱]、chi[吃]、shi[狮]、ri、zi、ci、si、yi [衣]、wu[乌]、yu[迂]、yin[因]、yun[晕]、ye[夜]、yue[月]、yuan[圆]、ying。相关内容解释:拼音字母指拼音文字所用的字母,也指汉语拼音方案采用的为汉字注音的二十六个拉丁字母。世界上第一套拼音字母是由腓尼基人创制的。由于腓尼基发达的航海和国际商业贸易,一方面经济需要及时编制商业文件,要求有一套普遍易懂的、简单方便的文字体系;另一方面,由于腓尼基从事国际商业活动,广泛接触并熟悉古代各国的文字,使它创造新的字母文字成为可能。于是,腓尼基人利用埃及的象形文字和巴比伦的模形文字创造了世界上第一套拼音字母。古代希腊字母和阿拉米亚字母都来源于腓尼基字母。希腊字母后来又发展为拉丁、斯拉夫字母;阿拉米亚字母后来发展为印度、阿拉伯、亚美尼亚、维吾尔等字母。可以说,腓尼基字母是现今世界各族字母的共同祖先。
