英语中的定语从句。

英语定语从句详解定语从句用来充当句中定语的主谓结构;它主要用于修饰句子中的名词、代词。而定语从句的位置常常是紧跟在被修饰的名词、代词的后面。在被修饰的名词、代词与定语从句之间往往有一个关系词将其前后两部分联系成一个整体,或是构成一个名词短语;或是构成一个代词短语。但从结构上说,关系词与从句是一个整体。排除句子的其他各部分,这种带有定语从句的名词短语或是代词短语的构成可演示如下:1)three signs that indicate a person is suffering from a panic attack rather than a heart attack三种意味着一个人是患有惊恐症而不是心脏病的迹象在这个带有定语从句的名词短语中:signs是:被修饰的名词; that是:关系词;that indicate a person is suffering from a panic attack rather than a heart attack是定语从句2)those who drink a lot 那些大量饮酒的人在这个带有定语从句的代词短语中:those是:被修饰的名词; who是:关系词;who drink a lot是:定语从句通过上面的演示,我们可以归纳出定语从句在句子中的位置、结构如下:被修饰的名词 / 代词 + 关系词 + 句子 (其中,"被修饰的名词/代词"在语法叫作"先行词".)要点提示:1)"先行词"与"关系词"的内在联系"先行词"与"关系词"之间实质上是互等、互换的关系。也就是说,关系词的作用就是将先行词所表达意义"代到"从句中来起作用。例如:They often become easily frightened or feel uneasy in situations (先行词)where (关系词)people normally would not be afraid .他们常在人们一般不会感到害怕的情况下却很容易感到恐惧或是感到不自在。(本句中的关系词where = 先行词(in)situations 。如果把这个复合句拆成两个分句,那就是:They often become easily frightened or feel uneasy in situationspeople normally would not be afraid in situations 由此可以看出,"先行词"与"关系词"之间实质上是互等、互换的关系)。 又例如:Rude people are those (先行词) whose (关系词)behavior shows little respect for the rules(先行词) that(关系词) the majority follows .不讲礼貌的人是指那些,他们的行为对大多数人所遵从的规则并不表示尊敬的人。由此我们还可以看出,"先行词"往往是分别重复出现在两个分句中的名词或代词。这也就是我们做定语从句的条件之必需。否则,"关系词"就无法去替代"先行词"而构筑定语从句了。这个道理就如同我们在计算机上"做剪贴以前要先做复制"一样。)2)"先行词"的意义决定"关系词"的选择"关系词"的选择往往是由"先行词"自身表达的意义,以及它在从句中的语法功能而决定的。这个意思就是说,假如"先行词"自身表达的意义是表示"人的意义"或是"物的意义",那么我们就相应地选择表示"人的意义"或是"物的意义"的"先行词"。"先行词" 在从句中的语法功能也是决定"关系词"选择的重要条件。比如说,同样都是表示"人的意义"的"先行词",如果它在从句中作主语,"关系词"就得用表示"人的意义"的主格形式,如果它在从句中作定语,"关系词"就得用表示"人的意义"的所有格形式。另外,有时"先行词"本身是表示事物的名词,而它在从句中却与介词构成了短语,在从句中充当状语,在这种情况下,我们就应该用"关系副词"而不能用"关系代词"了。例如:Some people who are successful language learners often fail in other fields . 有些在语言学习上很有成就的人,在其他领域常常一无所成。In our class , we have some students whose families are not in Wuhan.我们班上有些家不在武汉市的同学。There are many sounds which have a meaning and yet are not words .有许多声音有意义但不是词。Tell him to go to the classroom where we often have our English class .如果把这个复合句拆成两个分句,那就是:tell him to go to the classroom .We often have our English class in the classroom )告诉他去我们常上英语课的那间教室。(一) 关系词从前面的讨论中我们可以清楚地看出,关系词在定语从句的构成里是至关重要的。我们甚至可以说,掌握不好关系词就无法做成定语从句,也无法理解文中带有定语从句部分的意思。因此,我们首先讨论一下关系词的有关问题。定语从句中的关系词只有两类:关系代词和关系副词;没有连词。也就是说,定语从句中的所有关系词不但都有具体的意义而且都在从句中担任一定的成分。1)关系代词:who , whom , whose , which , that 等。who用于代替"表示人的意义"的先行词,并且在从句中作主语;在现代英语里,也可取代whom在从句中作动词的宾语。例如:I have no idea about the man who wrote the article .我不认识写这篇文章的那个人。The little boy who is singing there can recite quiet a number of Chinese poems .whom 用于代替"表示人的意义"的先行词,并且在从句中作动词或介词的宾语。在现代英语里,如果whom在从句中作动词的宾语,它与who可以通用;但是如果whom在从句中作介词的宾语,那么就只能用whom而不能与who通用了。当然,如果在口语或非正式文体中,介词没有提前,也就没有这点要求了。例如:Who is the girl whom ( who ) you talked to just now ? 刚才和你说话的那个女孩子是谁?Yesterday, I happened to meet , in the shopping center , the professor who ( whom ) I got to know at a party .昨天在购物中心,我碰巧遇见了那位我在一次聚会上认识的教授。 They are looking for the patient on whom doctors just performed an operation . 他们正在寻找那位医生刚刚给他做过手术的病人。 (句中的关系代词whom代替the patient ,在从句中作介词on的宾语,而且介词on提到关系代词的前面,所以who 和whom就绝不可以通用了,此处只能用whom 。)Who is the girl to who (whom) you talked just now ? (错误)(句中的关系代词whom(who)代替the girl ,在从句中作介词to的宾语,但是由于介词to已提到了关系代词的前面,who 和whom就绝不可以通用了,所以如果还继续使用who句子就错了。此处只能用whom 。)whose 用于代替"表示人或物意义"的先行词,在从句中作定语,往往与它所修饰的名词一起构成一个名词短语在从句中担当成分。Whose常表达"某人的、某物的"之意。例如:Do you know the name of that girl whose brother is your roommate ?你知道她的哥哥与你同寝室的那位女孩的名字吗?Water whose boiling point is at 100 degree Centigrade has no color, no flavor. 沸点在摄氏100度的水无色、无味。which 用于代替"表示事物意义"的先行词,在从句中作主语、宾语。例如:Views which are entirely new or foreign may also be hard to accept .那些全新的或是来自国外的观点或许也很难被接受。I"ve got a novel which you may like to read .我弄到一本你或许想看的小说。That was a fault which could not be forgiven . 那是不能饶恕的错误。that 既用于代替"表示人的意义"的先行词,也用于代替"表示事物意义"的先行词;在从句中既可以作主语,也可以作谓语动词的宾语,但是不能作介词的宾语。在一定范围内,that = who / whom / which 。例如:Views that (which ) are entirely new or foreign may also be hard to accept .那些全新的或是来自国外的观点或许也很难被接受。Salaried people that ( who) earn more than a few thousand dollars must pay a certain percentage of their salaries to the federal government .工薪在几千美元以上的人必须将工资中的一定百分比交付给联邦政府。Who is the girl to that you talked just now ? (错误)要点提示:定语从句中作宾语的关系代词可以省略;如果关系代词在定语从句中作宾语可以省略。例如:This is the book ( which ) you were looking for yesterday . 这就是你昨天找的那本书。I don"t like the novel ( that ) you are reading .我不喜欢你看的这本小说。Who is the man ( whom ) you"re talking about ? 你们谈论的那个人是谁?定语从句中,关系代词的单复数取决于先行词的单复数。例如:Those who are in their forties are required to have a physical examination this afternoon .(先行词Those是复数,关系代词who也就看作是复数,所以从句的谓语动词就用了复数形式are了。)请那些年龄在四十几岁的人于今天下午去进行体检。This is the magazine which was sent to me by post .(先行词the magazine是单数,关系代词which也就看作是单数,所以从句的谓语动词就用了单数形式was sent) 这是通过邮局寄给我的杂志。关系代词that 和which的区别 that 和which在一般情况都可以用于代替"表示事物意义"的先行词,在从句中作主语、宾语。但在下列情况下一般只用that而不用which :-- 先行词本身是all , everything , something , nothing , anything等不定代词时,例如:Anything that can burn is a source of heat energy .任何能够燃烧的东西都是热能源。There must be something that happened to you .你一定出了什么事。They had nothing that could cure of his disease .他们没有一点能治愈他疾病的东西了。-- 先行词已有序数词或形容词的最高级或the last, the only等作定语时,例如:This is the most impressive TV theater that has never been put on show before . 这是以前从未上演过的最有感染力的电视剧。That is the only way that leads to your success .那是通向你成功的唯一之路。We have to consider the first thing that starts our work .我们必须要考虑启动我们工作的第一件事。然而,在下列情况下却只用which而不用that:-- 当先行词表示事物意义,并且在从句中作介词的宾语,那么就只能用which 。当然,如果在口语或非正式文体中,介词没有提前,也就没有这点要求了。例如:The world in which we live is made of matter .我们生活于其中的世界是由物质组成的。Ocean currents affect the climates of the lands near which they flow . 洋流影响其流经的附近地区的气候。The world that we live in is made of matter.(正确。因为关系代词虽然在从句中作介词的宾语,但是介词没有提前,所以没有这点要求。)我们生活于其中的世界是由物质组成的。The world in that we live is made of matter.(错误。因为关系代词在从句中作介词的宾语,而且介词已经提前,所以必须遵从这点要求。)-- 在非限定性定语从句(关于这一点随后就要讲解)中,当关系词表示事物意义时, 只能用which 。这是语法所规定的,没有任何解释。例如:The sun heats the earth , which makes it possible for plants to grow .太阳给予大地热,这就使植物的生长成为可能。The most important form of energy is electrical energy , which is widely used in our daily life .最重要的能源形式是电能,它广泛地运用于我们的日常生活之中。-- as可以作为关系代词引导限定性定语从句、非限定性定语从句。例如:限定性定语从句 (常用于such … as和the same … as 等句式中)Such points as you"ve mentioned are really important in solving the problem .你提到的这些方面在解决这个问题上的确很重要。People such as you describe are rarely seen nowadays .你描述的这种人现在很少见了。This computer has the same functions as that one has .这台计算机有着和那台计算机一样的功能。非限定性定语从句 (as可以作为关系代词引导非限定性定语从句时,as是指全句:也就是说,将整个主句看成一件事或是一个事实;并对其进行补充、说明。这种非限定性定语从句既可以放在主句之前,也可以放在主句之后。) As I know , she hasn"t got married . 如我所知,她还未结婚。They won the first place in the game, as could be expected.可以预料,他们在比赛中得了第一。Professor Li is extremely popular among students , as is known to all of us . 如我们大家所知,李教授极受学生们的欢迎。2)关系副词:when , where , why 等。在定语从句,关系副词 = 介词 + which 。也就是说,每个关系副词里本身就已经含有了一个介词:when = 在什么时候,where = 在什么地方,why = 为什么原因,等。至于在英文中用哪个具体的介词,就得依具体情况而定了。when 代替表示时间的名词,而这个名词在从句中又与介词构成了短语,在从句中充当状语,例如:People will always remember the time when Hong Kong and Macao returned to our motherland .人们会永远记住香港和澳门回归祖国的那一时刻。He came at a time when we needed help . 他在我们需要人帮忙的时候来了。We don"t know the exact time when the English Evening will be held . 我们不知道英语晚会举行的确切时间。where 代替表示地点的名词,而这个名词在从句中又与介词构成了短语,在从句中充当状语。例如:The place where we"re to have the Speech Contest has not been decided yet.我们举行演讲比赛的地点还未定下来。He is living in a newly-built house where there used to be a pond . 他现在居住的新房是原先一个池塘的旧址。That is a beautiful campus where I made a lot dreams .那是一座我曾经在那儿有过许多梦想的美丽的校园。why 代替表示原因的名词,而这个名词在从句中又与介词构成了短语,在从句中充当状语。例如:He didn"t tell her the reason why he was so happy .他没有告诉她为什么他那么高兴的原因。The reason why she was late is not so acceptable .她迟到的原因不那么令人接受。They explained the reason to us why they had misunderstood us before .他们向我们解释为什么他们以前误解了我们的原因。介词+关系代词在这种结构中,关系代词若是表示人的意义,就只能用whom ;关系代词若是表示事物的意义,就只能用which 。而这种结构中较难解决的问题是介词的选择问题,因为这个问题的解决取决于多种因素:A)动词与介词的搭配B)名词与介词的搭配C)形容词与介词的搭配,等等。总之,要依从句的具体需要而定。例如:A)动词与介词的搭配He has found a good job for which he is qualified .( qualify + 名词+ for "使…具有…资格" )他找到了一份他能胜任的工作。The man to whom you talked just now will chair the meeting tomorrow . ( talk to + 名词 "与某人谈话" ) 你刚才与他谈话的那个人明天主持那个会议。He is bargaining with the landlord over the monthly price at which the apartment rents .名词+ rent at + 表示价格的词 "某物以某价格出租" )他在与房东就那套公寓出租的月租金进行磋商。B)名词与介词的搭配They are still living in the little house in which they"ve been lived for 15 years . ( in the house "在屋子里" )他们现在还住在他们已住了15年的那个小房子里。We"ve worked out a method by which our production can be raised on a large scale.( by a method通过某种方法) 我们已研制出了一个能大规模提高生产的方法。She didn"t realize the extent to which she had been distracted .( to extend "到某种程度" ) 她没有意识到她心烦意乱的程度。C)形容词与介词的搭配The secretary with whom the boss is not happy will be fired for her inefficiency . (happy with "对…表示满意")老板对其不满意的那个秘书将由于她没有工作效率而被解雇。I"ve found the job for which I"ve been eager for a long time.( eager for "渴望得到…" ) 我已找到了我渴望已久的那份工作。He is a learned man with whom we are familiar .(familiar with 熟悉…)他是一位我们熟悉的有学识的人。2)定语从句的种类在英文中,有两种定语从句:限定性定语从句与非限定性定语从句。这两种定语从句在其功能和形式方面都有明显的区别:限定性定语从句限定性定语从句与主句的关系很紧奏,对其先行词起限定、修饰的作用。如果将其去掉,会影响句子意思的完整性;有时甚至于引起费解、误解。例如:Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are located .为了加速他们各自所在国家的经济发展,热带雨林作为有价值的原木和其他资源正为人们所砍伐。Ocean currents affect the climates of the lands near which they flow. 洋流影响其流经的附近地区的气候。They explained the reason to us why they had hated us before.他们向我们解释为什么他们不喜欢我们的原因。非限定性定语从句非限定性定语从句在形式上就与主句很松散,它与主句之间有一个逗点","隔开;它对其先行词没有限定、修饰的作用,只起补充、说明的作用。有时也用它来对全句进行补充、说明。即使将其去掉,也不会影响句子意思。由于上述原因,非限定性定语从句在表达意思方面也有别于限定性定语从句。另外,非限定性定语从句在中文译文里,我们往往将其作为一个分句处理,而不把它作定语翻译。例如:Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy .(此句中,非限定性定语从句是对先行词a sphere进行补充、说明。)更早之前,巴比伦人曾试图绘制世界地图,但是他们把它绘制成平盘状而不是托勒密所采用的球体状。The combination of satellites, which transmit information , computers , which store information , and television , which displays information , will change every home into an education and entertainment center .(此句中,三个非限定性定语从句分别对三个先行词:satellites ,computers和television进行补充、说明。如果去掉这三个非限定性定语从句,那么句子可简化为:The combination of satellites , computers and television will change every home into an education and entertainment center .)卫星能传输信息,计算机能储存信息,电视能显示信息,把这些手段结合起来可以使每个家庭都成为教育娱乐的中心。The sun heats the earth , which makes it possible for plants to grow .(此句中,非限定性定语从句是对全句进行补充、说明,将全句表达的意思看成"一件事情)。太阳给予大地热,这就使植物的生长成为可能。The old man has a son , who is in the army .(此句中,非限定性定语从句是对先行词son进行补充、说明。但本句所传达的信息是:"这位老人只有一个儿子" 。如果将此句改写成限定性定语从句:The old man has a son who is in the army . 那位老人有一个在部队工作的儿子。那么,限定性定语从句就要对先行词son进行限定、修饰。这样一来,句子所传达的信息就变成了:"这位老人有一个儿子在部队工作,还有其他的儿子在干别的工作"。)那位老人有一个儿子,他在部队工作。

The C++ implementation can synchronize up to 9 channels.#include <message_filters/subscriber.h>#include <message_filters/time_synchronizer.h>#include <sensor_msgs/Image.h>#include <sensor_msgs/CameraInfo.h>using namespace sensor_msgs;using namespace message_filters;void callback(const ImageConstPtr& image, const CameraInfoConstPtr& cam_info){ // Solve all of perception here...}int main(int argc, char** argv){ ros::init(argc, argv, "vision_node"); ros::NodeHandle nh; message_filters::Subscriber<Image> image_sub(nh, "image", 1); message_filters::Subscriber<CameraInfo> info_sub(nh, "camera_info", 1); TimeSynchronizer<Image, CameraInfo> sync(image_sub, info_sub, 10); sync.registerCallback(boost::bind(&callback, _1, _2)); ros::spin(); return 0;}另外一种是基于策略的同步方式,也是通过消息头部数据的时间辍进行同步。Policy-Based Synchronizer [ROS 1.1+]:The Synchronizer filter synchronizes incoming channels by the timestamps contained in their headers, and outputs them in the form of a single callback that takes the same number of channels. The C++ implementation can synchronize up to 9 channels.The Synchronizer filter is templated on a policy that determines how to synchronize the channels. There are currently two policies: ExactTime and ApproximateTime.当需要同步的所有消息都带有时间辍的头部数据:ExactTimeThe message_filters::sync_policies::ExactTime policy requires messages to have exactly the same timestamp in order to match. Your callback is only called if a message has been received on all specified channels with the same exact timestamp. The timestamp is read from the header field of all messages (which is required for this policy).#include <message_filters/subscriber.h>#include <message_filters/synchronizer.h>#include <message_filters/sync_policies/exact_time.h>#include <sensor_msgs/Image.h>#include <sensor_msgs/CameraInfo.h>using namespace sensor_msgs;using namespace message_filters;void callback(const ImageConstPtr& image, const CameraInfoConstPtr& cam_info){ // Solve all of perception here...}int main(int argc, char** argv){ ros::init(argc, argv, "vision_node"); ros::NodeHandle nh; message_filters::Subscriber<Image> image_sub(nh, "image", 1); message_filters::Subscriber<CameraInfo> info_sub(nh, "camera_info", 1); typedef sync_policies::ExactTime<Image, CameraInfo> MySyncPolicy; // ExactTime takes a queue size as its constructor argument, hence MySyncPolicy(10) Synchronizer<MySyncPolicy> sync(MySyncPolicy(10), image_sub, info_sub); sync.registerCallback(boost::bind(&callback, _1, _2)); ros::spin(); return 0;}登录后复制由于该同步策略是当所有需同步的话题的时间辍严格相等时,才会触发回调函数。这就会导致以下一些问题:回调函数的触发频率必然小于等于这些话题中最小的发布频率;回调函数的触发并不十分稳定,有时候甚至会出现长时间不被触发的情况。如下图所示,某一次的间隔甚至长达10s左右。ROS提供了另外一种方法来实现数据的同步:ApproximateTime。与需要时间辍完全相同的ExactTime不同,该方法允许话题之间的时间辍存在一定的偏差。The message_filters::sync_policies::ApproximateTime policy uses an adaptive algorithm to match messages based on their timestamp.#include <message_filters/subscriber.h>#include <message_filters/synchronizer.h>#include <message_filters/sync_policies/approximate_time.h>#include <sensor_msgs/Image.h>using namespace sensor_msgs;using namespace message_filters;void callback(const ImageConstPtr& image1, const ImageConstPtr& image2){ // Solve all of perception here...}int main(int argc, char** argv){ ros::init(argc, argv, "vision_node"); ros::NodeHandle nh; message_filters::Subscriber<Image> image1_sub(nh, "image1", 1); message_filters::Subscriber<Image> image2_sub(nh, "image2", 1); typedef sync_policies::ApproximateTime<Image, Image> MySyncPolicy; // ApproximateTime takes a queue size as its constructor argument, hence MySyncPolicy(10) Synchronizer<MySyncPolicy> sync(MySyncPolicy(10), image1_sub, image2_sub); sync.registerCallback(boost::bind(&callback, _1, _2)); ros::spin(); return 0;}登录后复制从下图可以看出,虽然该方法允许时间之间存在偏差,但实际上偏差并不大。而且比起上一种方法,这个方法的回调函数的触发频率快多了。关于ApproximateTime,我还有一个不解的地方,这里做一下记录:If not all messages have a header field from which the timestamp could be determined, see below for a workaround.If some messages are of a type that doesn"t contain the header field, ApproximateTimeSynchronizer refuses by default adding such messages.以上这两句话,似乎自相矛盾。不知道是不是我理解的问题。。。从时间同步的角度看,话题消息内容中应该必须要带上时间辍信息才能进行同步,但第一句话却说可以允许一些消息不带时间辍?[补充于2021.2.11: 今天在使用ApproximateTime时同步了一个自定义的消息类型,发生了如下图所示的错误。后来查阅资料才发现是没有加header的原因,即没有时间辍,程序就无法根据时间进行同步。换句话说,该方法也是必须需要时间辍信息的。加上header后错误就没有了。]另外需要注意的是,使用message_filters时,需要在CMakeLists.txt和package.xml中添加相关依赖:# CMakeLists.txtfind_package( catkin REQUIRED COMPONENTS ... message_filters)# package.xmlfind_package( catkin REQUIRED COMPONENTS <build_depend>message_filters</build_depend> <build_export_depend>message_filters</build_export_depend> <exec_depend>message_filters</exec_depend>)登录后复制c++衡阳市民请关注领取补贴!巨摩互动广告ROS之订阅多个话题并对其进行同步处理(多传感器融合)2.0W阅读·11评论·22点赞2019年7月26日ROS回顾学习(5): 订阅多个话题并对其进行同步处理1963阅读·0评论·0点赞2020年2月4日ros_多消息同步回调(Synchronizer)5149阅读·2评论·10点赞2019年10月17日【ros】message_filters同步点云和图像数据1442阅读·9评论·6点赞2020年4月21日ROS MessageFilter订阅多个激光雷达话题进行同步处理2690阅读·1评论·7点赞2021年1月19日关于不同传感器时间同步----ROS提供的时间同步函数message_filters【ROS下linux源码,】1174阅读·2评论·4点赞2020年7月25日ROS多Topic接收的时间同步1052阅读·1评论·2点赞2020年9月20日将时间戳不同的点云和图像进行时间戳同步;把bag包里的图像和点云分割成一帧一帧的;把pcd转成bin格式。1491阅读·9评论·5点赞2021年4月19日ROS多传感器数据时间戳同步方案——message_filters::TimeSynchronizer1539阅读·0评论·1点赞2022年7月6日ROS官方教程[翻译]---message_filter的使用2.4W阅读·3评论·23点赞2017年8月22日ROS学习记录(二):订阅多节点时间同步518阅读·0评论·3点赞2020年9月18日ROS自学实践(10):ROS节点同时订阅多个话题并进行消息时间同步8118阅读·19评论·10点赞2020年5月23日ros-多订阅551阅读·0评论·0点赞2022年5月12日ROS知识点——生成点云,发布、订阅ROS点云话题1795阅读·0评论·2点赞2022年8月9日使用Publish/Subscribe 设计模式达到对象间数据同步1257阅读·0评论·1点赞2004年4月18日message_filters学习笔记805阅读·0评论·0点赞2021年8月13日ROS 搞懂多话题回调机制以及消息队列

欧米茄值得购买的八个理由

一.瑞士现代手表业的先驱 19世纪中后期,瑞士还是习惯以家庭作坊方式来加工怀表。而当时新大陆工业霸主美国却第一个应用标准机械化模式批量生产怀表,工业化管理的生产效率和成本肯定优于手工业。 创立于1848年的欧米茄,当时叫LaGenerale Watch Company,在瑞士并不算 历史 最悠久的,但欧米茄是瑞士第一个开创出以生产线模式制作零件的先例,换句话说机芯的样式和大小规格都有一定的标准,透过不同分工的生产线,可以快速产生更大量且规格统一的零件,这使得机芯的同款零件得以替换,提升了腕表组装与维修的便利性。于1894年装制出精密准确、品质优良且价格合理的19令机芯,当时一个银行家把这个大获成功的机芯命名为希腊字母的最后一个“Ω”,OMEGA从此成为这一品牌的正式名称。 二.精准计时 在石英革命之前,各国和各行各业都依赖精密的机械钟表。瑞士制表业兴起天文台时计竞赛,欧米茄在这些试验中获得了巨大的成功,创造了许多世界纪录。在1931年的日内瓦天文台试验中,欧米茄获得了所有六个类别的第一名,随之欧米茄的广告语成为“Omega – Exact time for life”。 而现在欧米茄腕表全线推行至臻天文台表认证,其精准度为其他官方认证天文台表的两倍;欧米茄至臻天文台表历经双重测试及认证。首先,机芯需经过瑞士官方天文台( COSC )认证测试,达到每日走时误差-4/+6秒的精准度标准。其次,整只腕表及其机芯又必须接受瑞士联邦计量研究院(METAS)设定的八项至臻天文台测试,确保每日走时误差为0/+5秒。 三.同轴机芯 瑞士传统擒纵技术成熟后,上百年来无人敢改;只有欧米茄敢为天下先,应用乔治·丹尼尔发明的同轴擒纵技术,同轴擒纵系统的设计理念在于将传统的杠杠式擒纵系统中擒纵叉与擒纵轮的垂直摩擦改为平行摩擦。品牌以1120机芯为基础推出了首款搭载同轴擒纵系统的2500机芯,新技术运行之初,欧米茄确实碰到了不少问题,但品牌没有退缩,先后推出了2500C(振频降至3.5Hz)、2500D(三层擒纵轮)等,缓解了“偷停”等问题之余,也积累了大量同轴擒纵系统的经验。 在2007年。当年,OMEGA(欧米茄)在充分吸收了2500系列机芯的基础上,推出了首款专为同轴擒纵系统而设的全新机芯——8500/8501。该机芯在设计上最大的亮点在于将副擒纵轮一分为二,从而将擒纵轮原本的双层结构改为三层结构。采用无卡度游丝,振频为3.5Hz,动力储存时间为60小时。同轴技术终于走向成熟,现在欧米茄机芯中全面推广,就连著名的1861机芯都改成了同轴3861机芯。 四.防磁15000高斯 进入20世纪以来,全球进入电气时代,手表碰到的最大威胁之一就是无处不在的电磁场,摆轮游丝的振动会受到磁场的影响,导致频率不均匀,影响手表的精度。 传统防磁手表都是从防字做文章,把机芯外部套一个软铁壳形成屏蔽电磁场的法拉第笼,万国工程师表也好,劳力士闪电针也好,都是这个套路。 只有欧米茄选择不屏蔽机芯,而是把机芯中所有可能受磁的零件全换成非铁磁材料:2013年,Omega的Seamaster Aqua Terra> 15,000高斯和Calibre 8508正式发布,这款机芯是欧米茄声称是世界上第一款真正的防磁机械表机芯。现在机芯内所有铁磁性零件均替换掉,由硅制成的摆轮游丝不需要法拉第笼,因此其防磁能力> 15,000高斯,现在手表表盘开有一个3点钟位置的日期窗口以及蓝宝石水晶表背。随着Master Co-Axial的引入以及最近的Master Chronometer和METAS认证标准,欧米茄慢慢地在全线产品中应用防磁机芯---结果之一就是闪电针不香了:) 五.阿波罗登月 在欧美国家很多人的记忆里,阿波罗登月计划是人类 历史 上一项非常伟大的创举,鼓舞和激励了整整一代人。 1964年,NASA开始寻找能够符合载人航天任务要求的腕表,欧米茄、劳力士、浪琴、汉米尔顿四个品牌提供了各自的产品方案,经过多次极端条件的测试,最后只有欧米茄超霸ST105.003胜出。1965年3月,NASA宣告欧米茄超霸成为载人航天项目的官方用表。 1969 年7 月21 日02:56:20 ,美国宇航员尼尔·阿姆斯特朗在月球上迈出了人类的第一步。当时他和他的同僚巴兹·奥尔德林都佩戴着超霸ST105.012,由于登月舱上的电子计时设备出现故障,阿姆斯特朗将他的超霸留在了舱内。15 分钟后,奥尔德林离开“鹰”登月舱踏上月球表面,佩戴于奥尔德林腕间的超霸ST105.012成为了第一枚登上月球表面的腕表。 这是人类的伟大进步,也是欧米茄 历史 上的永恒记忆! 六.奥运计时 自1932年以来,欧米茄已连续28次担任奥运会的官方计时合作伙伴---确切地说,国际奥委会(IOC)与官方计时器OMEGA的全球合作伙伴关系将一直延续到2032年,包括2022年北京冬季奥运会一直延续到XXXV奥运会(2032年)。迄今为止,欧米茄参与了27场夏季和冬季奥运会,欧米茄(Omega)的计时设备和技术被用来记录世界上最有才华的运动员的表现。 欧米茄还开发并引入了多个世界最尖端的运动计时技术,包括电子发令枪、泳池触摸壁和Scan"O"Vision MYRIA——终点拍照相机,该相机可以在一秒钟内拍摄10000张数码照片。 七.表款丰富 欧米茄产品线丰富,可正装可运动,可上九天可入五湖四海,绅士淑女选择多多,四大产品系列,分别是:海马、 星座 、蝶飞、超霸。 能下水的海马系列,最早诞生于1948年,这个 历史 比水鬼更早,防水从150米 300米 600米 1200米直到11000米,跨越所有深度,造型从正装AT一直到运动夸张的PROBLOF; 星座 系列的设计可以说非常具备标志性,起初表盘两边的托爪只是为了更好地稳固蓝宝石镜面,而如今已经成了 星座 的经典标志。那个谁都戴呢, 星座 能会差吗? 蝶飞属于欧米茄的正装表系列,堪称正装表界的标杆产品,整体都是“低调”的款式,中规中矩的表盘设计,深入人心。 超霸必然联想到“登月”,欧米茄的超霸计时码表在这个行业里可以说是名头颇盛,欧米茄超霸现在已发展出不同材质组合多种复杂功能的庞大家族。 八.相对保值 劳迷看到保值这两个字,估计会嘲笑了;实际上抛去那几个钢运动劳,剩下大多数Rolex都不溢价。实质上绝大多数欧米茄表款跟DJ的保值率差别不大:想想看一只6万的DJ是原价买的,而一只3万的欧米茄蝶飞我打了85折,最终你去看看二手价格,相对投资来看,保值率肯定相差不多。 这也是符合经济规律的,资本一定会涌入任何能获取超额利润的产品,游资们一定会把市场价抬价到市场平均回报率附近的。 欧米茄作为跟劳力士知名度匹敌的品牌,其表款不像小众品牌那样,二手市场庞大稳定,所以我说欧米茄手表也是相对保值的。 说了这么多,最后想说一句,欧米茄也不是神表,现阶段小毛病也不少,比如近年来新品设计不够给力,市场运作上不节制,但金无足赤,人无完人,相信欧米茄自己也能认识到缺点,我就不多说了。

定语从句that不能省略

  一、定语从句that不能省略情况   1.非限制性定语从句中,that有其他意思不可省   2.有不定代词时   3.有only时   4.有序数词时   5.指人又指物时   6.有形容词最高级时   二、定语从句中关系词的省略与不省略   1.关系代词which,whom,who,that在定语从句中作宾语时可以省略.   Here is the man (who/that/whom)you"re been looking for.   以下情况不能省略:   (1)在介词+whom与介词+which中,whom,which不能省略.   Do you know any shops nearby in which I can buy flowers?   That is the headmaster with whom my father was talking just now.   注:当介词放在动词后时,which,whom就可以省略.   Who is the man (whom) you talked with just now?   (2)在非限制性定语从句中,作宾语的关系代词也不能省略.   Mr Green,whom you know,is the tallest in our school.   The elephant is like a spear,as anybody can see.   (3)在the same ...as,such...as,as...as,the same...that中,as,that即使作宾语,也不能省略I have bought the same bicycle as you have (bought).(指同类用as)   This is the same book that I read the day before yesterday.(that指同一个)   (4)当由and,but,or等连词连接两个或两个以上的定语从句修饰一个先行词时,第一个关系代词可省,但第二,第三个不可省略.   This is the book (which) I read yesterday and which I find very interesting.   2.当that在从句中作补语时可以省略.   He is not the man (that) he used to be.   She is all (that) a teacher should be.   3.在there be 结构中出现定语从句,或在定语从句中出现there be 时,用作主语的关系代词也可省略.   There is a man downstairs (who) wants to see you.   This is the best dictionary (that) there is in the library.   4.状语的省略   (1)当先行词是reason,而且定语从句中作原因状语时,关系代词可用why,that,也可以省略.   The reason (why/that) he failed was his laziness.   That is the reason (why) I did it.   (2)当先行词是way,且在定语从句中作方式状语时,关系代词可用in which,that,也可以省略.   The way (in which/that) these comrades look at problems is wrong.   That was the way (in which/that) she worked the problem out.   注意:当关系代词在定语从句中作主语时,不省略.   例如:I don"t know the way that/ which leads to the top of the mountains.   (3)当先行词是time时,关系代词可用when,that 或省略.   The second time (that) I saw him was in 1980.   I don"t know the exact time (when/that) the sports meet will take place.   注意:关系代词作宾语有时也不能省略.   拓展   1同位语从句   在复合句中用作同位语的从句叫同位语从句,常常跟在fact,idea,opinion,news,hope,belief等名词后面,用以说明该名词表示的具体内容,可以由名词、代词、短语及句子来充当同位语从句。   同位语从句是名词从句,其作用相当于一个名词,对前面抽象名词的进一步的说明和解释。   2定语从句   定语从句是由关系代词和关系副词引导的从句,用来修饰名词或代词,起到定语的作用,所以叫做定语从句。定语从句的作用是作定语修饰主句的某个成分,通常分为限定性和非限定性从句两种。   定语从句不同于单词作定语的情况,它需要放在被修饰的词(即先行词)之后,一般由关系代词来引导,关系代词必须放在定语从句之首。被修饰的词叫先行词,由关系词(关系代词或关系副词)引出。   3同位语从句与定语从句的区别   1、引导同位语从句的that是连词,在从句中不充当任何成份,而引导定语从句的`that是关系代词,除起连接作用外,还在从句中充当主语、宾语或表语等,如:   The idea that computers can recognize human voices surprises many people.   计算机能够识别人的声音的想法使许多人感到惊奇。(同位语从句,that在从句中不充当任何成份)   The idea that he gave surprises many people.他提出的观点令许多人感到吃惊。   (定语从句,that在从句中作gave的宾语)   2、引导词的不同   what,how,if,whatever等可引导名词性从句,但不引导定语从句。   3、同位语从句与前面的名词是同位关系,即说明它前面名词的内容;而定语从句与前面的名词是修饰与被修饰关系,即限定它前面的名词范围,或补充一些情况。如:   The news that l have passed the math exam is true.我通过了数学考试这一消息是真的。   (同位语从句,即从句所表达的意思就是前面名词的内容)   The news that he told me just now is true.他刚才告诉我的消息是真的。   (定语从句,从句对前面名词起修饰限制作用,即“他告诉我的”那个消息,而不是别的消息)   4、定语从句的先行词是名词或代词;而同位语从句的先行词只能是名词,而且仅限于idea,fact,hope,news,doubt,truth,information,suggestion,question,belief,conclusion等少数名词。而且when,where,why引导的定语从句的先行词一定分别是表示时间、地点和原因的名词,而三者引导的同位语从句的先行词则肯定不是表示时间、地点和原因的名词。I have no idea when they will come.我不知道他们什么时候来。(同位语从句)   I"ll never forget the days when I lived there.我永远不会忘记我住在那儿的日子。(定语从句)
2023-07-24 01:00:531

This month是什么时态?

这个不好说啊,很多时候并不是一个短语就可以决定句子时态的。单看this month的话,可能是过去时,未来时和完成时。过去时:This month I went to see the concert. (这个月我去看了演唱会,指这个行为发生在本月,并且已经过去)将来时:I‘ll go to Japan this month. But I don"t know the exact time. (本月我将去日本,但我不知道确切时间。指的是去日本这个动作将发生在本月,且还未发生)完成时:Only this month I have earned 1000 dollars. (光这一个月我就已经挣了1000美元,指的是动作在本月已经完成,强调完成。)

浪琴“L2.628.4.78.3”与“L2.628.6.78.3”的机芯一样吗?

L2.628.4.78.3与L2.628.6.78.3都是采用L619.2自动上链机芯,这款机芯是以ETA2892A2为基础芯打磨而成的,走时准确可靠。x0dx0ax0dx0a美度天文台认证的贝伦赛丽、完美、舵手系列,大都采用ETA2824-2及2836-2机芯,从稳定性及准确性来说,都与浪琴名匠的L619.2机芯不相上下。x0dx0ax0dx0a浪琴LONGINES的起源可追溯到1832年,由年轻商人奥古斯特阿加西在瑞士SaintLimier创办和开始钟表生意。拥有百余年历史的浪琴表,起源于公元1832年制表师奥古斯都。向来坚持最好的品质的工作哲学,对时间工艺不断地努力创新,浪琴表已然成为精准的代名词了!x0dx0ax0dx0a浪琴表之所以成为精准的同义字,全归功于对时间工艺的不断努力。1899年浪琴表赞助由路易士·雅曼达(Louis-Amadeus)伯爵所领导的北极探险活动,提供专为极地各种气温变化所设计的五支怀表,并受到极力赞扬。伯爵写道:“无论受到多么恶劣的气候变化,浪琴表始终保持最精准的时间”_TheLongineschronometerskepttheexacttime,despitetheenormoustemperaturevariationstowhichtheyweresubjected._在这次探险之后,许多其它的探险家都选择了浪琴表作为指定定时器。x0dx0ax0dx0a另外一项伟大的记录,是1894年巴尼船长(CaptainJ.E.Bernier-Arctic)驾船从美国到北极探险。

从句中which的的正确用法是什么

  定语从句的关系代词Which若先行词指物则代替先行词在定语从句中充当主语或宾语,以下是由我整理关于从句中which的用法的内容,希望大家喜欢!  从句中which的用法   This is the pen which was given by my friend.   先行词 指物代替先行词在定语从句中充当主语   This is the pen which my friend gave to me.   先行词 指物代替先行词在定语从句中充当宾语   下面是他和that在定语从句中的区别及用法:   that which在代物时常常可以通用,但有时只宜于用which ,不用that   (1) 关系代词前有介词时.   This is the hotel in which you will stay.   (2) 如有两个定语从句,其中一句的关系代词是that,另一句宜于用which.   Let me show you the novel that I borrowed from the liberary which was newly open (新开放) to us.   注意2that which在代物时常常可以通用,但有时只宜于用that ,不用which.   (1) 先行词是形容词最高级或者它的前面有形容词最高级时   This is the best that has been used against air pollution(反对空气污染) in cities.   English is the most difficult subject that you will learn during these years.   (2) 先行词是序数词,或它的前面有一个序数词时   He is the last person that I want to see.   (3) 主句中已有疑问词时   Which is the bike that you lost?

(7) 有两个定语从句,其中一个关系代词已用which,另外一个宜用that   Edison built up a factory(办了一个工厂) which produced things that had never been seen before.   定语从句的关系副词 Where的用法:若先行词指地点且其在定语从句中充当地点状语.   This is the house+I was born in the house.(=I was born there)   介词 短语 副词   =This is the house where I was born.这就是我在那儿出生的房子.   先行词 关系副词   in which I was born.   介词+关系代词   which I was born in.   关系代词   这里作介宾的which和that可以省略   that I was born in   which的一般用法   1、在后置的非限制性定语从句中代替上文出现的事物或情况(单数或复数)。   2、在问句中作为疑问代词,在名词从句中作为连接代词用,其含义为“哪个、哪些”。   3、如果非限制性定语从句的先行词不是指主句内容,而是指具体的人、时间、地点,则不用which。   定语从句中的that和which用法区别   that和which在从句里都可以做宾语和主语,做宾语时可以省略。在定语从句中,有种说法叫"关宾省",意思是关系代词在限制性定语从句中作宾语可以省略,不管是that,which,还是whom。但是which能引导非限制性定语从句,that则不行。   其次,记得以下只能用that的几种情况:   1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。   如:   Please tell me anything that you know about the matter.   有关此事,凡是你所知道的请告诉我。   2. 当先行词被any, few, little, no, all, much, some等词修饰时。   如:You can take any seat that is free.   任何空着的座位你都可以坐。   3. 当先行词为序数词或被序数词所修饰时。   如:   This is the fourth film that has been shown in our school this term.   这是我们校本学期放映的第四部电影。   4. 当先行词为形容词最高级或被形容词最高级修饰时。   如:   This is the most interesting story book that I have ever read.   这是我读过的一本最有趣的 故事 书。   5. 当先行词被the very, the only, the last, the just, the same等修饰时。   如:   The only thing that we could do was to wait.   我们唯一能做的事就是等待。   注意:先行词被the same修饰时,关系代词也可用as。   如:I need the same book that / as you have.   我需要有你一样的书。   6. 当先行词既包含人又包含物时。   如: They are talking of the heroines and their deeds that interest them.   他们正在谈论他们感兴趣的女英雄及她们的 事迹 。   7. 当先行词是疑问代词who,which,what或主句以这些词开头时。   如:   Who that has ever worked together with him doesnu2019t admire him?   曾经和他一起工作过的谁不钦佩他?   8. 当先行词为主句表语或关系代词为从句表语时。   如:   Our school is no longer the place that it used to be.   我们的学校现在已不是过去的那个样子了。   9. 先行词为time时,当time表示次数,引导词用that, 可省略。 当表示时间,可用that或when引导,都可省略。   如:   I did"t remember the exact time (when/that) I arrived in Shanghai last month.   我不记得上个月到达上海的确切时间了。   最后,请注意以下几种只能使用which的情况:   1. 在“介词+关系代词”结构中,关系代词必须用which。   如:   This is the reference book of which the teacher is speaking.   这就是老师正在谈及的那本参考书。   注意: 如果介词不放在修饰事物的限定性定语从句的句首, which就可换为that, 例如:   This is the question which/that weu2019ve had so much discussion about. =This is the question about which weu2019ve had so much discussion.   这就是我们已经多次讨论过的问题。   2. 先行词为“those+表事物的复数名词”时, 关系代词通常只用which而不用that。   如:You should grasp well those skills which may be used in the future work.   你应该掌握好这些可以用到未来工作中的技能。   最后,记得这个特殊情况吧:当先行词是表示原因或方式的名词时,可以用that引导定语从句,相当于介词+which,that可以省略。   如:   He didnu2019t like the way that (=in which) she speaks to his mother.   他不喜欢她对他的母亲那样说话。   Imagine the speed that (=at which) he drives the car.

1000字英语作文.. 关於 听英语歌对学好英语有帮助 的..谢谢

For learning English well,we can do these things:We should listen to tapes more,read more English books,take English grama notes at every class.And,we can also ask more questions when we study.Another way to learn English well I think is watching more English movies and listening to more English songs,that"s really a good way,because besides learning we can also have fun.If we do like these,I think we can learn English well.How to Learn English Well After China became the Official member in WTO (World Trade Organization) and the Reform & Opening Policy is being implemented deeper and deeper, the international communications in all domains has become far more than before. English, as an important tool for cross-cultural communication, has got its status among thousands of languages. People in China have been aware of this trend, but the way to master a foreign language is not always smooth for every one. Someone who has learnt English for over 12 years cannot open his mouth and speak smoothly in English. It is not only his tragedy but our teaching system"s. Here I want introduce fellow English lovers some experience according to my feelings in Learning English. First of all, develop our interest in English at the beginning of our study. To develop interest in English study is not very hard. We may have the feeling of satisfaction and achievement from our English study when we are able to say something simple in English, talk with others or foreigners in English and act as others" interpreters. Please do NOT neglect interest is the first teacher. As you know English is a language that represents the sounds of pronunciation; but Chinese language is not. The grammar and structure between these two languages are not very much alike. In fact, besides the tens of thousands of offensive vocabulary words, the problems in listening and speaking are more outstanding. You can never hear a whole meaningful fragment, let alone to say something in your own words. Therefore, in my opinion, listening and speaking skills is the most important thing of all the five skills in mastering a language --- listening, speaking, reading, writing and translation (interpretation). Here, I want to show you some basic methods to train yourselves listening and speaking competence: Listening: before you want to understand what others have said, you should try your best to let yourself clearly hear what they just said. That is, you should pay attention to the stress of a word and a sentence, the sound-linking, the tone intervals and etc. You can listen to the recorded training material by looking at the original lines. And if you insist in doing so at least a month, you will find you can hear and understand 40% of words in a particular listening material. Since you will understand the meaning of a whole sentence by only catching part of words, the 40% words you have caught are enough for you to get the 70% of the holistic meaning. Of course, it is the basic way to set your feet in speaking training. You should go on experiencing in harder and harder exercises and not stop though you feel you have made great progress. Watching English movies, English TV programs, listening to English songs and learn English on some special occasions are also excellent and vivid English learning ways as we may combine English with some certain scenes to deepen our memory. Speaking: Nowadays, it is too embarrassing for you to master only 2,000 words; however, it doesn"t matter for you to make speaking exercises. Someone will say it is too easy when he gets into an oral training material; and he will feel the material is not suitable for him. But we should know clearly that speaking skill is not reading comprehension. Sometimes you cannot speak out ONE word though maybe you know all the meaning of the sentence. To practice speaking competence, the material should not be too difficult. The aim is to make your mouth active with some easy-operating dialogs. So a good and suitable textbook should be the one that is native and suitable and helpful for you. “INSTANT”--- it is an “instant” age now. We have instant noodle, instant porridge, and instant dinner even instant marriage. But we should not believe that there is an instant language-learning method existed! We should get our mind and set down to learning English step by step. I think from very beginning that the course of mastering a foreign language is a quality improvement from quantity accumulation. As to reading comprehension, the more the vocabulary words you know, the better you can read and accurately understand the meaning. Intensive Reading: When we read the intensive articles, we should make notes of the new words and phrases and good sentences. After reading them, we may ask ourselves some questions about them by using such words: Who, What, Why, When and Where. Then try to answer them in our own words. Extensive reading: We must train our ability to scan, skip and read fast, namely, the ability to catch the key words, the topic sentences and the drift of the articles. Reading speed: Three ways to improve our reading speed: 1) Reading the articles from the beginning to the end without intervals so to catch the rough idea of the articles on the whole. Never waste too much time on some new words and single sentences. 2) We may keep time when reading articles.3) When reading articles, we can point at the words with our finger or pen point and our eyes move with the finger quickly so that we are able to read very fast. Now I want to take my own experience for example. Usually I read an article by “two-times reading method”, that is, I read it for two times. At the first time, I aim at training of reading speed and efficiency. And the second time, I aim at broadening my vocabulary words capacity and the feeling towards a particular language. At the very beginning, I took the book Active Readers for reference. I trained myself reading skill from reading speed. I recorded the exact time I started and keep the time I finished reading; and then I calculated the words I read in a particular period. I forced myself to read as fast as possible; it became very natural eventually. This is the first time for every try, aiming at reading speed. At the second time the essential thing is to learn vocabulary words. This course is very concrete and no short-cut to go along. Notes should be made whenever we study any articles. We may follow this advice: Don"t read book without making notes. As we know that notes are the summarization, the core content, our understanding and the abbreviations of the books. Our notes are much thinner than the books so that we can learn them by heart easier and can often review and read them. We may also record our notes on tapes so as to often listen to them easier, to deepen our impression and to lighten our burden of memory. Sometimes it is needful to draw some tables and illustrations that are very impressive, visual and concise. Newspaper as good reading materials can widen our horizon and richen our knowledge. I recommend you should buy some English newspaper at regular time; current events are more interesting for you to read, because sometimes reading is an extremely boring thing. Let"s shift into our training of writing skills. It should be sorted in the higher level of using a language. And the fundamentality is words" usage and the way of thinking in the target language. Like one of our Chinese saying “After you smoothly recite Three Hundred Poems from Tang Dynasty, you will naturally become a poet.” So is English. Reading with thinking is an effective way to improve your writing competence. Many teachers have said keeping dairies was the best way to practice recording the real things happened around you. I have tried this advice for an interval time. But I haven"t insisted on it, partly because the interest towards it was lost. However, I found another way that was really effective, that is, making pen pals with peers abroad. For instance, I had a pen pal from Sri Lanka when I was in high school. At that time, she was still a primary school student. But her English was FAR better than me, because the English is their second language and they teach and learn at school in English. During the happy time when we wrote each other, I could notice the improvement of my written English; all the reason is I am interested in the culture there and the feeling of achievement. As to the writing techniques, they are very important and can help you compose an article efficiently and make your composition active and attractive to readers. For some English learners, their minds become blank as they hold their pens for writing compositions. They don"t know where they should start and what they should begin with. The commonest situation is assembling arbitrarily. Therefore, their writing level cannot be improved and just remains where it was. If they could get some information about writing techniques and knowledge, their compositions would be much better! As follows, I want to show you some helpful writing knowledge and techniques: a. First you should know there are mainly 5 kinds of article styles, that is, Narration, Exposition (Description), Diary, Letters and Notice (Note). Every style has its own particular structures that you should pay much attention to. Since the limited space here, I don"t want to analyze them respectively. b. Try to use the basic sentence structure to compose your article. Don"t always like to use BIG and LESS-USED words. You should endeavor to master some useful expressions and set phrases and add suitable tenses; a good composition will be born. c. The more you read good articles and excellent examples, the easier you will find when you start to write. d. Pay attention to the situation you describe. A Chinese saying goes Sing Different Songs on Different Hills. You should clearly concern who you are writing to or whether it is a casual composition or a comparatively serious one and etc. In a word, the lack of properly expressing something in written tasks exists commonly. But in this fiercely competitive society, it seems more and more important. If you follow the tips above and insist doing so, you will win eventually in this domain. The last aspect I want to mention is translation or interpretation. To tell the truth, it is the highest level for an English learner. The course of translation or interpretation is the one using all kinds of lingual knowledge synchronically. Compared with English-to-Chinese translation, the Chinese-to-English translation is comparatively easier. 呵呵,希望能帮到你
