competition和game和match有什么区别?

( ̄△ ̄)每天晚上一篇英语知识普及英语罐头本文是我的第361篇英语知识文章前两天刚发完东京奥运会相关的推文,罐头菌就想起这组英语里面最经典的词组辨析competition,race,match。英语里面,关于“比赛,竞赛”的表达有不少,而对于他们完全摸不着头脑,不知道其区别的人大有人在,因此,罐头菌今天就来讲解一下competition,race,match这几个单词的辨析。1.matcha sports competition or event in which two people or teams compete against each other两人或者两队对抗的体育赛事或者比赛按照惯例,假如要辨析一个中文意思相似的词语,最好的方法之一就是先找出它的英语解释。从上面的英英解释来看,match更多侧重在于“两人或者两队之间的比赛”,可以理解为双方对抗的比赛。例如说:a tennis match 网球比赛(两个人对打)a football match 足球比赛(两个足球队的较量)a boxing match 拳击比赛 (两个人的对打)France won the match 28-19.法国队以28比19的比分赢下了比赛。2.racea competition in which all the competitors try to be the fastest and to finish first全部比赛者都比拼谁最快或者第一个完成的比赛和上面的match不一样,race并没有限制参赛的人数,但它在参赛的目的上做出了区别。Race更加侧重于那些“竞速”类的比赛。例如说:running race 赛跑horse race 赛马She won the 100-meter race in 11.06 seconds.她以11.06秒的成绩赢下了100米赛跑。3.competitiona situation in which someone is trying to win something or be more successful than someone else某人尝试以某事物或者某目的赢下别人最后再来看competition,从解释上来看,competition似乎并没有什么限制,既不想match那样限制参赛人数,也不像race那样限制了参赛的目的。因此,competition是一个综合性的词组,它的意思非常广泛。它既能指任何正规性的比赛,也能指商业商业社会中,由于利益而产生的竞争。例如说:U.S.-China competition 中美竞争chess competition 国际象棋竞赛There"s a lot of competition between computer companies.这两家电脑公司之间有着非常多的竞争。最后我们来再复习一遍:match更多指“两人或者两队伍”之间的比赛race侧重于表示“竞速”为目的的比赛competition意思非常广泛,任何赛事或者竞争都能使用今天的课都教完了,那么下面A,B,C几张图里面的比赛,分别都能用competition,race,match哪个词来表示呢?A.篮球比赛B.摩托车比赛C.冲浪比赛这是英语罐头,每天我都会分享最实用的英语知识日积月累,你也能成为英语大神假如你想学习更多英语知识,欢迎关注我!

英语翻译,整篇翻译

妈妈曾经告诉我一个故事。在非洲,一只羚羊(羚羊)每天早上醒来,想到的第一件事是,“我必须跑得比狮子更快,否则我会被杀死的。”同时,狮子从梦中醒来。第一件事就是狮子想着,“我必须追跑得最慢的羚羊,或我会饿死。于是,几乎在同时,羚羊和狮子起来冲向太阳升起。这是生活:充满着机遇和挑战(挑战)。不论你是羚羊还是狮子,你必须在太阳升起的时候。对于学生,它是一样的。如果我们不努力学习,迟早,我们将落后于其他同学。起初,我不知道这个词的“考试”的意思。后来我知道考试也是一种竞争。在比赛中,总会有赢家和输家。等我长大了,我要知道竞争。在人的一生中,必须有竞争,所以人们可以提高。每次我看见孩子们玩游戏,听到他们的笑声,我希望我的年龄了。然而,我记得我的父母的话:“你必须努力学习,为了有一个好的未来。”所以,我拿起我的笔,开始努力学习了。我还是不确定的竞争真的意味着什么。有一天,我正在一个英语演讲比赛的一部分。当我走到舞台上,我看见其他学生很友善地看着我。我突然明白了竞争。这不是我的老师和父母说我残酷。事实上,竞争是相反的:它是一种必要的。

写一篇100左右的英语作文 My view on competition

In contemporary society, there is the competition everywhere. For example, there are competitions among students in school and there are competitions among colleagues at work. We all live in the competition.The competition is important and necessary for people to achieve success in their life.As the saying goes: " life is action, action is the competition. " As far as I am concerned,if the society does not have the competition, just like a person without a soul.Each coin has two sides. On the one hand, there are many benefits of competition. First of all, it is the competition that promotes the development of society. Competition is the driving force for social development. Secondly, Competition may be able to arouse our greatest potential. Because of competition, students will work harder and try their best to learn the lesson well. Last but not least, Competition makes us a more objective evaluation of our own. Only we recognize themselves, can we find our own limitations and improve our level and ability. So many people enjoy the challenge and competition because it allows them to become more powerful.On the other hand, competition also has some disadvantages. Firstly, according to Xinhua News Agency reported that 200, 000 people commit suicide every year due to competition. Because of competition, everyone must bear the enormous pressure. Secondly, some businessmen do a lot of illegal things in order to win in the competition. These acts lead to a bad influence on society and impede the progress and development of society. Thirdly, Competition makes people more alienated. If you want to maintain a favorable position in the competition, you have to study hard in order to make yourself more combat.When we face competition, we should treat the competition properly and should make good use of competitive advantages and avoid competitive disadvantages. Only we have learned to coexist with the competition, our life will be more colorful.

你好: 对乙酰氨基酚片中文又名:扑热息痛 药理: 药效学 本品镇痛作用的机制尚未十分明了,可能是通过抑制中枢神经系统中前列腺素的合成(包括抑制前列腺素合成酶)以及阻断痛觉神经末梢的冲动而产生镇痛,后者可能与抑制前列腺素或其他能使痛觉受体敏感的物质(如5-羟色胺、缓激肽等)的合成有关。解热作用则可能是通过下视丘体温调节中枢而起作用,可能与下视丘的前列腺素合成受到抑制有关。 药动学 口服后自胃肠道吸收迅速、完全( 在高碳水化合物饮食后服药可能降低吸收),吸收后在体液中分布均匀,约有 25%与血浆蛋白结合。小量时(血药浓度<60μg/ml)与蛋白结合不明显, 大量或中毒量则结合率较高, 可达43%。本品90~95%在肝脏代谢,主要与葡糖醛酸、硫酸及半胱氨酸结合。中间代谢产物对肝脏有毒性作用。半衰期β一般为1~4小时(平均2小时), 肾功能不全时不变,但在某些肝脏疾患者可能延长, 老年人和新生儿可有所延长, 小儿则有所缩短。口服后0.5~2小时血药浓度可达峰值, 剂量在650mg 以下时血药浓度为5~20μg/ml, 作用持续时间为3~4小时。 哺乳期间妇女服用本品650mg,1~2小时报乳汁中浓度为10~15μg/ml; 半衰期β为1.35~3.5小时。本品主要以与葡糖醛酸结合的形式从肾脏排泄,24 小时内约有3%以原形随尿排出。 适应症: 本品为乙酰苯胺类解热镇痛药,其解热作用与阿司匹林相似,而镇痛作用较弱。适用于缓解轻度至中度疼痛,如感冒引起的发热、头痛、关节痛、神经痛以及偏头痛、痛经等。本品因仅能缓解症状,消炎作用极微,且不能消除关节炎引起的红、肿、活动障碍,故不能用以代替阿司匹林或其他非甾体抗炎药治疗各种类型关节炎。但本品可用于对阿司匹林过敏、不耐受或不适于应用阿司匹林的病例,如水痘、血友病及其他出血性疾病患者(包括应用抗凝治疗的病例),以及消化性溃疡、胃炎等。应用本品时必要时还须同时应用其他疗法解除疼痛或发热的原因。 用法用量: 1.成人常用量口服。一次 0.3—0.6g,每 4小时 1次,或每日 4次;一日量不宜超过 2g,疗程为退热一般不超过 3天,为镇痛不宜超过 10天。 2.小儿常用量口服。按体重每次 10—15mg/kg或按体表面积每天 1.5g/平方米,分次服,每4—6小时 1次;12岁以下小儿每 24小时不超过 5次量,疗程不超过 5天。 [制剂与规格]对乙酰氨基酚片(1)0.38(2)0.5g 口服,每次0.25-0.5g,一日3-4次.最大剂量一日2g,疗程不宜过10日.儿童:2-3岁日160mg,4-5岁日240mg,6-8岁日320mg,9-10岁日400mg,11岁日480mg,每4小时服一次,或必要时服.长期使用有肾病综合症,避免长期大剂量使用. 禁 用慎用: (1)交叉过敏反应:对阿司匹林过敏者对本品一般不发生过敏反应。但有报告在因阿司匹林过敏发生喘息的病人中,少数(<5%)可于服用本品后发生轻度支气管痉挛性反应。 (2)本品可通过胎盘,故应考虑到孕妇用本品后可能对胎儿造成的不良影响。 (3)虽然哺乳期妇女服用本品后在乳汁中可达一定浓度,但在哺乳婴儿尿中尚未发现过本品或本品代谢产物排出。 (4)下列情况应慎用;①乙醇中毒、肝病或病毒性肝炎时,有增加肝脏毒性作用的危险;②肾功能不全,虽可偶用,但如长期大量应用,有增加肾脏毒性的危险。 3岁以下儿童及新生儿避免使用。肝病时发生不良反应的危险性加大,有严重心、肾或肺疾患的患者应严格控制使用此药。 给药说明: 给药前应注意患者肝、肾功能,对长期较大剂量用药者应定期复查(包括血象、肝肾功能等)。 ()在大量用药或长期治疗期间应定期作造血功能及肝功能检查。 长期使用有肾病综合症,避免长期大剂量使用. 不良反应: (1)一般剂量较少引起不良反应,对胃肠刺激小,不会引起胃肠出血。少数病例可发生粒细胞缺乏症、高铁血红蛋白血症、过敏性皮炎(皮疹、皮肤瘙痒等)、肝炎、血小板减少症等。 (2)长期大量用药,尤其是在肾功能低下者,可出现肾绞痛或急性肾功能衰竭(少尿、尿毒症)。 (3)服用超量(包括中毒量)时,可很快出现恶心、呕吐、胃痛或胃痉挛、腹泻、厌食、多汗等症状,且可持续 24小时。2—4天内出现肝功能损害,表现为肝区疼痛、肝肿大、黄疸。第 3—5天肝功能异常可达高峰,第 4~6天可出现明显的肝功能衰竭,表现为肝性脑病(精神、神志障碍,躁动,嗜睡)、抽搐、呼吸抑制、昏迷等脑水肿症状,以及凝血障碍、胃肠道出血、弥散性血管内凝血、低血糖、酸中毒、心律失常、循环衰竭、肾小管坏死。曾有报道一次服用 8—15g导致严重肝坏死,并于数日内死亡。 白细胞减少,皮疹.精神病性反应.严重过量时可引起肝肾损害,死亡.长期使用有肾病综合症,避免长期大剂量使用. [心血管系统]心血管性虚脱是严重过量引起肝中毒的一个表现。 [呼吸系统]它能使对阿司匹林过敏患者的支气管痉挛加重,因此,在同时应用此药和复方阿司匹林时应注意此点。严重中毒时可抑制呼吸中枢。 [神经系统]过量致有肝坏死时可出现精神错乱、激动和注意力障碍,但通常不会有意识丧失。 [消化系统]过量可引起急性肝损害,偶伴有肾小管坏死,伴胰腺炎更罕见。有报道3例每天服5~8g共数周,血清肝细胞酶短暂性升高,组织学证明为中毒性肝炎,长期饮酒者对此药有异乎寻常的敏感性。 [泌尿系统]长期服用大剂量对乙酰氨基酚可致有肾病,包括乳头坏死性肾衰。 [造血系统]可以认为对乙酰氨基酚是潜在的诱发血小板减少的药物。 [皮肤]可发生荨麻疹以及偶见皮炎伴瘙痒,有发生固定性药疹者。 相互作用: (1)在长期饮酒或应用其他肝酶诱导剂,尤其是应用巴比妥类或其他抗痉药的患者,长期或超量服用本品时,更有发生肝脏毒性反应的危险。 (2)抗凝药:大量或长期应用本品时,因可减少凝血因子在肝内的合成,有增强抗凝药的作用,故抗凝药的用量应根据凝血酶原时间进行调整。 (3)长期大量与阿司匹林、其他水杨酸盐制剂或其他非甾体类消炎药合用时(如每年累积用量至 1000g,应用 3年以上时),可明显增加肾毒性(包括肾乳头坏死、肾及膀胱癌瘤等)的危险。 (4)与抗病毒药齐多夫定(zidovudine)合用时,由于两药可互相降低与葡糖醛酸的结合作用而降低清除率,从而增加毒性,因此应避免同时应用。 二氟尼柳(Diflunisal)使血中对乙酰氨基酚浓度升高。口服避孕药加速它在肾脏的排泄,而降低它的作用。能诱导肝酶的药物使它的中毒更严重。它与香豆素类药合用,使凝血时间更延长。

小灶细胞明显异型性是什么意思

  异型性由于分化的程度不同,肿瘤的细胞形态和组织结构与相应的正常组织相比,有不同程度的差异,病理学将这种差异称为异型性。  肿瘤的异型性有两个方面:细胞异型性和结构异型性。 (一)肿瘤的细胞异型性(cellular atypia)有以下表现:(1)肿瘤细胞通常比相应正常细胞大;(2)肿瘤细胞的大小和形态很不一致(多形性),可以出现瘤巨细胞,即体积很大的肿瘤细胞。但是,有些分化甚差的肿瘤,其瘤细胞很原始,体积不大,大小和形态也可以比较一致;(3)肿瘤细胞核的体积增大。胞核与细胞浆的比例(核浆比)增高。例如,上皮细胞的核浆比正常时多为1:4~1:6,恶性肿瘤细胞则可为1:1;(4)核的大小、形状和染色差别较大(核的多形性)。可出现巨核、双核、多核或奇异形的核。核内DNA常增多,核深染(hyperchromasia),染色质呈粗颗粒状,分布不均匀,常堆积在核膜下;(5)核仁明显,体积大,数目也可增多;(6)核分裂像常增多,出现病理性核分裂像,如不对称核分裂、多极性核分裂等。  良性肿瘤细胞一般异型性较小,恶性肿瘤细胞则常具有高度异型性。上述瘤细胞的形态,特别是胞核的多形性和病理性核分裂,常为恶性肿瘤的重要特征,在区别良恶性肿瘤上有重要意义。异型性越大,表示肿瘤组织和细胞与相应正常组织的差异越大。异型性是肿瘤组织和细胞出现成熟障碍和分化障碍的表现。一般来说,异型性越大,成熟程度和分化程度就越低。有些恶性肿瘤细胞分化很差,异型性显著,称为间变性肿瘤(anaplastic neoplasm)。间变性的肿瘤细胞常具有多形性(pleomorphism),即肿瘤细胞的大小和形状变异很大。间变性肿瘤多为高度恶性的肿瘤。(二)肿瘤组织在空间排列方式上与相应正常组织的差异称为肿瘤的结构异型性(architectural atypia)。如食道鳞状细胞癌中,鳞状上皮排列的极向显著紊乱;胃腺癌中腺上皮失去极向,形成的腺体很不规则;子宫内膜腺癌中,腺体之间正常的内膜间质消失等等。良性肿瘤的细胞异型性一般较小,但可有不同程度的结构异型性。恶性肿瘤的细胞异型性和结构异型性都比较明显。

对乙酰氨基酚比乙酰水杨酸稳定的原因

一、适应病症上的区别:1、乙酰水杨酸:阿司匹林对血小板聚集的抑制作用,因此阿司匹林肠溶片适应症如下:降低急性心肌梗死疑似患者的发病风险预防心肌梗死复发中风的二级预防降低短暂性脑缺血发作(TIA)及其继发脑卒中的风险降低稳定性和不稳定性心绞痛患者的发病风险动脉外科手术或介入手术后,如经皮冠脉腔内成形术(PTCA),冠状动脉旁路术(CABG),颈动脉内膜剥离术,动静脉分流术预防大手术后深静脉血栓和肺栓塞降低心血管危险因素者(冠心病家族史、糖尿病、血脂异常、高血压、肥胖、抽烟史、年龄大于50岁者)心肌梗死发作的风险。其他用途:用途一:解热镇痛药,用于发热、疼痛及类风湿关节炎等。用途二:是应用最早,最广和最普通解热镇痛药抗风湿药。具有解热、镇痛、抗炎、抗风湿和抗血小板聚集等多方面的药理作用,发挥药效迅速,药效肯定,超剂量易于诊断和处理,很少发生过敏反应。常用于感冒发热,头痛、神经痛关节痛、肌肉痛、风湿热、急性内湿性关节炎、类风湿性关节炎及牙痛等。是《国家基本药物目录》列入的品种。乙酰水杨酸也是其他药物的中间体。2、对乙酰氨基酚用于感冒发热、关节痛、神经痛及偏头痛、癌性痛及手术后止痛。本品还可用于对阿司匹林过敏、不耐受或不适于应用阿司匹林的患者(水痘、血友病以及其他出血性疾病等)。二、不良反应上的区别1、乙酰水杨酸(1)胃肠道症状胃肠道症状是阿司匹林最常见的不良反应,较常见的症状有恶心、呕吐、上腹部不适或疼痛等。口服阿司匹林可直接剌激胃黏膜引起上腹不适及恶心呕吐。长期使用易致胃黏膜损伤,引起胃溃疡及胃出血。长期使用应经常监测血像、大便潜血试验及必要的胃镜检査。应用阿司匹林时最好饭后服用或与抗酸药同服,溃疡病患者应慎用或不用。增强胃黏膜屏障功能的药物,如米索前列醇等,对阿司匹林等非甾体抗炎药引起的消化性溃疡有特效。(2)过敏反应特异性体质者服用阿司匹林后可引起皮疹、血管神经性水肿及哮喘等过敏反应,多见于中年人或鼻炎、鼻息肉患者。系阿司匹林抑制前列腺素的生成所致,也与其影响免疫系统有关。哮喘大多严重而持久,一般用平喘药多无效,只有激素效果较好。还可出现典型的阿司匹林三联症(阿司匹林不耐受、哮喘与鼻息肉)。(3)中枢神经系统神经症状一般在服用量大时出现,出现所谓水杨酸反应,症状为头痛、眩晕、耳鸣、视听力减退,用药量过大时,可出现精神错乱、惊厥甚至昏迷等,停药后2~3天症状可完全恢复。大剂量时还可引起中枢性的恶心和呕吐。(4)肝损害阿司匹林引起肝损伤通常发生于大剂量应用时。这种损害不是急性的作用,其特点是发生在治疗后的几个月,通常无症状,有些患者出现腹部的右上方不适和触痛。血清肝细胞酶的水平升高,但明显的黄疸并不常见。这种损害在停用阿司匹林后是可逆的,停药后血清转氨酶多在1个月内恢复正常,全身型类风湿病儿童较其他两型风湿病易出现肝损害。阿司匹林引起肝损害后,临床处理方法是停药,给予氨基酸补液、VitC及肌苷等药物,口服强的松,症状一般在1周后消失。(5)肾损害长期使用阿司匹林可发生间质性肾炎、肾乳头坏死、肾功能减退。长期大量服用该品可致氧化磷酸化解耦联,钾从肾小管细胞外逸,导致缺钾、尿中尿酸排出过高,较大损害是下段尿中可出现蛋白、细胞、管型等。有人认为,部分肾盂癌是滥用阿司匹林等止痛药的继发性并发症。(6)对血液的影响阿司匹林通常不改变白细胞和血小板的数量及血细胞比容、血红蛋白的含量。但长期应用阿司匹林可导致缺铁性贫血。(7)心脏毒性治疗剂量的阿司匹林对心血管没有重要的直接作用。大剂量可直接作用于血管平滑肌,而导致外周血管扩张。中毒剂量可通过直接和中枢性血管运动麻痹作用而抑制循环功能。(8)瑞氏综合征阿司匹林应用于儿童流感或水痘治疗时可能引起瑞氏综合征。瑞氏综合征是一种急性脑病和肝脏脂肪浸润综合征,常常发生于某些急性病毒性传染病以后。病因尚不明确,但普遍认为与下列因素有关:如病毒(流感病毒和水痘病毒)、水杨酸盐、外源性病毒如(黄曲霉素)、内在代谢缺陷等,各因素可相伴存在或各因素间相互影响而造成。临床上病毒性感冒时不主张使用阿司匹林。(9)交叉过敏反应对该品过敏时也可能对另一种水杨酸类药过敏。但是对该品过敏者不一定对非乙酰化的水杨酸类药过敏。2、对乙酰氨基酚少数病例可发生过敏性皮炎(皮疹、皮肤瘙痒等)、粒细胞缺乏、血小板减少、高铁血红蛋白血症、贫血及肝、肾功能损害等。三、用药禁忌上的区别:1、乙酰水杨酸(1)禁用情况有出血症状的溃疡病或其他活动性出血时;血友病或血小板减少症。溃疡病或腐蚀性胃炎;葡萄糖6磷酸脱氢酶缺陷者(该品偶见引起溶血性贫血);痛风(该品可影响其他排尿酸药的作用,小剂量时可能引起尿酸滞留);肝功能减退时可加重肝脏毒性反应,加重出血倾向,肝功能不全和肝硬变患者易出现肾脏不良反应;心功能不全或高血压,大量用药时可能引起心力衰竭或肺水肿;肾功能衰竭时可有加重肾脏毒性的危险。(2)慎用情况有哮喘及其他过敏性反应时对于甲亢危象而引起高热的病人慎用(3)限制或禁止服用对阿司匹林、布洛芬、拿百疼等药物过敏者。蚕豆症患者,因为阿司匹林可导致溶血。有肾病、胃溃疡、糖尿病、痛风症等的患者,必须得到医生的许可才能服用。儿童和青少年,不宜使用阿司匹林治疗伤风感冒。血友病病人或其他出血倾向者不宜服用。孕妇。2、对乙酰氨基酚对本品过敏者禁用。肝肾功能不全者慎用。孕妇及哺乳期妇女慎用。

socks5的区别

SOCKS是一组由Internal工程工作小组(IETF)所开发出来的开放软件开放标准,用来处理网络安全的事宜。SOCKS象一堵墙被夹在 Internal服务器和客户端之间,对于出入企业网络的资讯提供流量和安全的管理。SOCKS这个名词并不是一组英文字头的缩写,而是一个和 TCP/IP的Socket端口有关的安全标准,一般防火墙系统通常是象网关(Gateway)一样是作用在OSI模型的第七层也就是应用层上,对 TCP/IP的高级协议,如Telnet、FTP、HTTP和SMTP加以管制,而SOCKS作用在OSI模型的第五层也就是会话层上,象一个代理一样对客户端到服务器端或服务器和服务器之间的数据联系提供安全上的服务。由于SOCKS作用在会话层上,因此它是一个提供会话层到会话层间安全服务的方案,不受高层应用程序变更的影响。 Socks代理只是简单地传递数据包,而不必关心是何种应用协议(比如FTP、HTTP和NNTP请求),所以Socks代理服务器比应用层代理服务器要快。

过年做近视手术,能告诉我近视眼激光手术原理吗?

在眼的屈光系统中,角膜的屈光力占全部屈光力的 70%,角膜屈光力的轻度改变即能明显影响近视的度数。PRK及LASIK两种手术正是通过切削中央角膜,使之变薄而降低其屈光力来达到矫正近视目的的。 PRK多应用于治疗中低度近视,但由于破坏了角膜的正常解剖结构,术后可出现角膜上皮下雾状浑浊、青光眼或高眼压、眩光和回退等并发症。LASIK可以保持前部角膜组织的正常解剖结构,能够减轻术后角膜组织愈合反应所引起的上皮下浑浊和屈光回退,预后性较好,术后恢复和稳定性也较好,适合于中高度近视和近视散光的治疗。但LASIK也可能出现并发症,如感染、欠矫或过矫、角膜穿透、医源性角膜散光、继发性圆锥角膜、角膜瓣不规则、眩光等等。这些并发症如果及时发现并处理得当,大部分不会留下后遗症,也不会影响疗效。但是有些并发症确实妨碍视力恢复,比如术前近视术后过矫成高度近视;或术前无散光,术后成为高度散光等等。如果手术致存留的角膜太薄,则无法采用再次手术予以补救。又如,术中角膜穿透或术后继发严重的圆锥角膜,都可能令患者不得不接收角膜移植手术,给患者带来新的麻烦。
