连词while的用法
连词while的用法
连词while根据上下文有以下不同作用和含义。
一、引导时间状语从句
译作“当……时”。例如：
1. Make hay while the sun shines.
趁着有太阳晒晒草。（乘机行事，抓紧时机。）
2. We must work hard to gain more knowledge
while we are young. 趁着现在还年轻，我们必须刻苦学习，获得更多的知识。
二、引导让步状语从句
常放在句首，译作“尽管”、“虽然”，比although或though语气要轻。例如：
1. While I believe it is true, I cannot prove it.
虽然我相信那是真的，但我无法证明。
2. While any kind of athletic shoe can provide a certain amount of rebound, energy-return sneakers are designed to maximize this effect.
虽然任何一种运动鞋都能提供一定的反弹力，但回力运动鞋能够使这种效果最大化。
三、引导条件状语从句
相当于as long as，译作“只要”。例如：
1. While there is life, there is hope.有生命，就有希望。
2. While a spark of life remains, it is a doctor's duty to save the patient.
只要病人还有一息生机，医生就有责任挽救。
四、引导原因状语从句
相当于since，有“既然”的意思。例如：
1. You'll never save any money while you're so extravagant. 你这么奢侈，永远存不下钱来。
2. I'd like to get it settled today while we're at it.
既然我们着手干了，我想今天就把它干完。
五、连接并列句
表示对比，相当于whereas，译作“而”、“可是”。
例如：
1. An outdoors man will soon become pale if he changes to an indoor job, while a desk clerk will take on a tan after a short vacation in the sun. 从事室外工作的人如果调到室内工作，不久肤色就会变白；而一个伏案工作的文员出去度个短假，就会被太阳变黑。
2. Motion is absolute while stagnation is relative.
运动是绝对的，而静止是相对的。
六、连接并列句
表示递进，相当于and what is more, 译作“并且”、“而且”。例如：
The new man-made fibres are more hardwearing than natural fibres and greatly reduce mending, while good ready-made clothes are cheap and plentiful.
新的人造纤维比天然纤维耐磨，因此能大大减少修补工作，而且做好的衣服价廉物美，数量也多。
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。

when做并列连词的用法
when 和引导时间状语从句的从属连词when 是不同的。这主要表现在以下几个方面： 1. 位置：when 引导时间状语从句时，该从句可放在主句之前也可放在主句之后；而并列连词when 只能位于两个分句之间，而且前面常常有逗号。例如：Come when you please. 你高兴来就来吧。（when 为从属连词）When I saw him，he was writing to a friend of his. 我看见他时，他在给一个朋友写信。（when 为从属连词）I was taking a walk，when I came across him. 我正在散步，突然碰见了他。 2. 意义：when 作从属连词用时，它所引导的从句表示主句中谓语动词动作发生的时间，即作“当……时”解；而并列连词when 连接的两个分句中，第一个分句表示的是背景，第二个分句表示的是一种突然的、意想不到的情况或过早发生的事情。when 通常含“这时突然”之义。例如：I was thinking of this，when I heard my name called. 我正想着这件事，突然听到有人叫我的名字。I had just fallen asleep，when the boor-bell rang. 我刚入睡，门铃突然响了起来。这种意义在孤立的句子中可以理解到，在文章中更能体会得到。如在“ I was wandering through the street when I caught sight of a tailor's shop ”一句中，“在街头漫步”只是“看见有家缝纫店”的时间，其后作者怎样走进缝纫店，想要什么样的衣服，怎样受到伙计的奚落，又怎样受到老板的奉承等情景均与“漫步街头”没有直接的因果关系。 3. 时态：when 引导的时间状语从句中可以根据句意的需要用一般现在时.一般过去时、过去进行时、分别说明现在，过去，甚至将来的行为；并列连词when 后面的分句中通常用非延续性动词的一般过去时，其前表时间的分句中可用：（ 1 过去进行时表示过去某时间正在进行的动作。 例如： I was cooking when I heard her knocking at the door. 我正在做饭，突然听到她敲门的声音。 He was thinking about the problem，when an apple fell to the ground. 他正在思考这个问题，突然有一只苹果掉到了地上。 （2 ）was /were going to，was / were about to，was / were on the point of 表示过去某一时间将要发生的动作。 例如： I was just going when he came in. 我正要走，这时他就进来了。 We were about to start when it began to rain. 我们刚要动身天就开始下起雨来了。 He was on the point of leaving，when someone knocked at the door. 他刚要走就有人敲门。 （3 ）过去完成时表示过早发生的事情。请看下述两种场合： （a ）过去完成时和含否定意义的hardly，scarcely，nearly 连用，和just，little 连用，或者与否定词not 连用时，表示“刚……，就……”的意思。 例如： I had hardly opened the door when he hit me. 我刚一开门他就打了我一下。 I had nearly reached the town，when the young man suddenly said very slowly，“ Do you speak English ”我快要进城了，年轻人突然慢慢地说：“你会讲英语吗” I had been there little more than a week when I set to work in earnest. 我到那儿还不超过一个星期就开始认真干起活来。 I had not been reading for half an hour when I heard steps outside.
并列连词用法归纳
并列连词用法归纳 并列连词有and、but、or、for、nor、so以及not only…but also…、both…and…、neither…nor…、either…or…、as well as等。 并列连词是构成英语并列句的桥梁，英语中两个或两个以上的互不依从的对等句子通常都是通过并列连词来体现的。现分类讲解如下： I．表示增补关系：这类并列连词通常是and、nor、so、both…and…、not only…but also…、neither…nor…、as well as…等。 1. and可用来连接两个或两个以上的单词、短语或句子，表示一种顺接的关系。如： My brother and I study in the same school. Our knowledge may come from the books and from practice. We are singing and they are dancing. 2. so表示肯定的增补，而neither、nor表示否定的增补，三者常位于句首，要求主谓倒装。例如： Tom got up at six this morning. So did Mike. 汤姆今晨六点钟起床，迈克也是。 He can’t swim, neither can Mary. 他不能游泳，玛丽也是。 3. both…and…可用来连接两个并列的主语、谓语、宾语、表语和状语等。当连接两个并列的主语时谓语动词通常用复数形式。如： Both Li Ping and Mary are going to the Great Wall tomorrow. He can both swim and skate. They speak both English and French. 4. not only…but also…、neither…nor…这两个并列连词和both…and…的共同特征是都连接两个相同的句法单位，如主语、谓语、宾语、表语和状语等。其不同之处主要是它们连接两个并列主语时谓语动词用就近原则。如：Not only the students but also the teacher gives the money to our school. 不仅学 生为我们学校捐了款而且这位老师也捐了款。 Neither he nor I am right. 他不对我也不对。 5. 注意not only…but also…强调的后者，而as well as…强调的是前者。当as well as…引导并列主语时，谓语动词与前面的主语保持一致。如：He as well as his students gets up at six o’clock. 不仅他的学生们而且他也是六点钟起床。 II．表示选择关系：这类并列连词通常是or、either…or…等。 1.这两个连词主要表示一种选择关系，注意的是either…or…通常引导两个相 同的句法单位，当连接两个并列主语时谓语动词用就近原则。如： He is either at home or at school. 他或者在家或者在学校。 Either he or I am wrong. 不是他错就是我错。

并列连词when相关的句式归纳
并列连词when相关的句式归纳 2006年普通高等学校招生全国统一考试(辽宁卷)中有这样一道单项填空题:He was about halfway through his meal ___ a familiar voice came to his ears. A.why B.where C.when D.while 解析:答案是C。此处when作并列连词,表示“就在此刻(and just then)”“,突然(and suddenly)”,该句译为：“饭刚吃到一半儿的时候，熟悉的声音传到了他的耳朵里。” 这里when引导的并不是我们所认为的时间状语从句而是并列句。when的意思是这时而不是当什么时候。在这个句型中when所引导的从句恰恰是句意的重心，when在这里起到一个修辞的作用表示后一动作的发生的出乎意料，而前面一句是为后一句谓语动词的发生提供背景。when 为并列连词。在我们的教材中并不鲜见。如： I'd just about given myself up for lost when I was spotted by a ship. 我正感到绝望时，一艘船发现了我。【Unit 3 Book 3】 33. She had just finished her homework ___ her mother asked her to plactised playing the piano yesterday.【09福建卷】 A. when B. while C. after D. since 7. Tom was about to close the window ___ the attention was caught by a bird. 【10全国卷】 A. when B. if C. and D. till 1．be (just) about to do... when...

They were on the point of giving up when the captain encouraged them fiercely to save the ship． 就在他们快要放弃努力时, 船长鼓励他们竭尽全力挽救轮船。
