连词while考点知识归纳

连词while考点知识归纳 while是大家比较熟悉的一个词,但是许多人对它的了解是不全面的,你可能只知道它表示“当……的时候”,甚至可能还知道它与when, as的用法区别。但是,非常遗憾,你所知道的这些东西都是有关while用法的“基础知识”,却不是一般英语考试的“考点知识”。请看下面两道考题: 1. _________ the Internet is of great help, I don’t think it’s a good idea to spend too much time on it. A. If B. While C. Because D. As 2. In some places women are expected to earn money _________ men work at home and raise their children. A. but B. while C. because D. though 这两道题的答案均为B,即均选while。你知道这是为什么吗?下面我们就来归纳一下连词while的“考点知识”。 考点知识一:表示让步,意为“尽管”“虽然”。如: While the work was difficult, it was interesting. 虽然工作有难度,但很有趣。 While we don’t agree we continue to be friends.尽管我们意见不同,我们还是朋友。 While he admitted that he had received the stolen jewellery, he denied having taken part in the robbery. 尽管他承认他收受了盗窃的珠宝,但他否认参与了抢劫案。 While I did well in class, I was a poor performer at games. 虽说我学习不错,我运动却不行。While a few became richer, many did not. 虽然一些人变得更富有了,但多数人并非如此。 考点知识二:表示对比或转折,意为“而”“但是”。如: I went swimming while the others played tennis. 我去游泳,而其余的人则去打网球了。 Air is a fluid but not a liquid, while water is both a fluid and a liquid. 空气是流体不是液体,水是流体也是液体。 Some people waste food while others haven’t enough.一些人糟踏食物而另一些人却食不果腹。注:这样用时,while引出的句子通常位于末,但有时也可位于句首。如: While most children learn to read easily, some need extra help. 大多数儿童学会阅读很容易,有一些儿童却需要特别帮助。 While some languages have 30 or more different vowel sounds, others have five or less. 有些语言有30个或更多的元音,而其他语言只有5个或更少的元音。 现在我们回过头来分析一下上面的两道题:第1题中的while表示让步,全句意为:虽然因特网很有帮助,但我还是认为在其上花太多的时间不是个好主意。第2题中的while表示对比,全句意为:有些地方妇女挣钱,而男子则在家里持家和带孩子。

语法复习二十一:连词 连词分为并列连词和从属连词两大类。并列连词是连接主语与主语,谓语与谓语,句子与句子,分词与分词的词,它要求前后两部分有相同的形式和语法作用;而从属连词一般连接主句与从句,从句形式有名词性从句,定语从句和状语从句等。 (一)并列连词: 并列连词可用来连接词与词,词组与词组,分句与分句。常用的并列连词有:and(和),as well as(既…又),both … and(不但…而且),not only … but also(不但…而且),not … but(不是…而是),neithe r … nor(既不…也不),either … or(不是…就是),or(或者),but (但是),yet(然而),for(因为),so(所以),while(而),when(这时)等。如:Both my brother and my sister are teachers./ His room is bright but mine is gloomy(暗沉沉的)./ He can not only repair radios but also fix them./ It is a glorious(光荣的)yet difficult task./ Strike while iron is hot. (二)从属连词 从属连词是指在复合句中引导从句的连结词。常见的从属连词有: 引导时间状语从句的:after, before, when, as, while, since, until, till, as soon as 引导原因状语从句的:because, since, as 引导让步状语从句的:although, though, no matter(无论), even if (though) 引导条件状语从句的:if, unless, once, so (as) long as 引导结果状语从句的:so … that …, such … that … 引导目的状语从句的:so that …, in order that … 引导比较状语从句的:as … as …, not so (as) … as …, … than … 引导方式状语从句的:as if … 引导主语,宾语或表语从句的连词主要有:that, whether, if三个。其中that 和whether 间或还可以引起同位从句和状语从句。 (三)某些用法比较特殊的从属连词用法区别 1、当while, when, as引导时间状语从句时的区别:①while引导的状语从句中动词必须是持续性。谓语动词多为进行时,或状态动词的一般时。while 的这些用法可用when代替,等于“at the time that”, “during the time that”。例如:Please keep quiet while (when) others are studying;② when除可指一段时间外,还可用来指一点时间,等于“at the time”,也就是说when引出的时间状语从句中的谓语动词可以是终止性的,也可以延续性的。因此主句和从句的谓语可以是一般时,进行时,或完成时。例如:When I went into the lab, the teacher was doing an experiment.(when不能换成while)He often makes mistakes when he is speaking English.(when可换成while)③as常可与when,while通用,但强调“一边、一边”。例如:
