when的用法总结大全 when的用法你知道多少，今天给大家带来when的用法，希望能够帮助到大家，下面就和大家分享，来欣赏一下吧。 when的用法总结大全 when的意思 adv. 什么时候,(用于时间的表达方式之后)在那时,其时,当时conj. 在…时,既然,如果 pron. 什么时候,那时 n. 时间，时候,日期,场合 when用法 when可以用作副词 when的基本意思是“什么时候”。可用作疑问副词,用来询问某事曾发生或将要发生的时间,引导特殊疑问句; 还可用作关系副词引导限制性定语从句、非限制性定语从句和表语从句,表示“是…时候的事”。 when可用作从属连词,引导状语从句,表示时间时作“当…时,在…的时候”解; 表示条件时作“如果,要是”解; 表示对比时作“既
然,考虑到”解。当when所引导的从句的主语和主句的主语一致时,常将其主语、系动词或助动词省去,只留实义动词或表语,或者改写为短语。 when所引导的时间状语从句用一般现在时代替将来时,用现在完成时代替将来完成时。 when用作副词的用法例句 When did that happen?那件事是什么时候发生的? They stood respectfully when he entered the room.当他走进房间时，他们都恭恭敬敬地站着。 Iron will melt when it is made very hot.当铁烧得很热时就会熔化的。 when可以用作连词 when可用作从属连词,引导状语从句,表示时间时作“当…时,在…的时候”解; 表示条件时作“如果,要是”解; 表示对比时作“既然,考虑到”解。当when所引导的从句的主语和主句的主语一致时,常将其主语、系动词或助动词省去,只留实义动词或表语,或者改写为短语。 when所引导的时间状语从句用一般现在时代替将来时,用现在完成时代替将来完成时。
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.
when 的用法 一、when 用作副词。 1. 用作疑问副词，引导特殊疑问句。(什么时候，何时 [at what time ])例如： ①When will you come to see me? ②When are they going to visit the Great Wall? 2. 用作连接副词，通常用来引导名词性从句[主语从句、表语从句、同位语从句、宾语从句]及起名词作用的“when ＋动词不定式”结构。(什么时候，何时 [at which; on which ])例如： ①When he comes is not known. [主语从句] ②The morning is when I am busiest. [表语从句] ④I don't know when the plane takes off. [宾语从句] ⑤I don't know when to leave for London. [宾语] 3. 用作关系副词，引导限定性定语从句和非限定性定语从句。(在…的时候 [at/on/in/during which])例如： ①Do you still remember the days when we stayed in America? ②The day will come soon when the Chinese astronauts will go to the moon. ③It happened ten years ago, when I was a child. ④We will go to the countryside at the beginning of June, when the summer harvest will start. 二 . when 用作连词。 1. 用作从属连词，意为“当……的时候[at the time when ]”，引导时间状语从句。例如： ①They learned a lot from the peasants when they stayed in the village. ②It was snowing when he arrived at the station. 【点津】如果 when 引导的从句中的主语和主句中的主语一致，且从句中的谓语动词是“be ＋分词”或从句主语是 it ，则 be 动词及其主语常可省略。例如： ③When（ he was ）asked why he was late, he made no answer. ④I'll tell him about it when（ it is ）possible. 2. 用作从属连词，意为“一……就……”，引导时间状语从句。[immediately after]例如： ①We will stand up when the teacher comes into the classroom. 老师一进教室我们就起立。 ②Fire the rockets when I give the signal. 3. 用作从属连词，意为“还没 / 刚刚/刚一……就”，引导时间状语从句。[immediately after]例如： ①I had hardly opened the door when he came in. 我刚一开门，他就进来了。 ②I had not been reading for half an hour when I heard someone call my name. 【点津】hardly…when和no sooner…than的结构要注意三点：意思为“一A就B“；A句通常用完成时态；hardly 和 no sooner 位于句首时要注意部分倒装。 4. 用作从属连词，意为“倘若，如果”，表示条件。例如： ①Turn off the switch when anything goes wrong with the machine. 如果机器发生故障，就把电源关上。 ②He will be likely to recover when he is operated on. 5. 用作从属连词，意为“既然，尽管”，表示让步。例如： ①Why use metal when you can use plastic?既然能用塑料,为什么用金属? ②They kept trying when they knew it was hopeless. 尽管他们知道那件事没有希望，可是他们还在不断地努力。6. 用作并列连词，意为“在那时，届时;就在这时”，表示时间。这时主句中可以用过去进行时，过去完成时或“ was/were about to do sth. ”结构。 ①Last night I was about to go to bed when the phone rang. ②I was cooking in the kitchen when someone knocked at the door. ③He had just finished the book when supper was served. 7. 用作并列连词，意为“虽然、然而、可是”，表示转折。例如： ①He usually walks to work when he might take a bus. 虽然他可 以坐公共汽车上班，但他却常常步行上班。 ②I had only twenty dollars when I needed thirty to buy the dictionary.我需要 30 美元买那本字典，可是我只有20美元。 8. 用作并列连词，意为“而、却”，表示对比。例如： How can he say that everything is fine when it's obvious that it is not? 他怎能说一切都好呢？情况显然不是那样。 三 . when 用作代词[which time]。 when 作为代词常常位于介词之后，意为“那时，什么时候”。例如： ①Since when have you been studying Japanese? 【点津】since when 作引导词时是“介词（since）+关系代词（when）”的结构，when意为which time。since when常引导非限制性定语从句，从句应用完成时态。 ②I came here in 1949, since when I have been engaged in this work. 我1949年到这里，从那时起我就担任这项工作。 ③We came back on Tuesday, since when we have been working in the repair shop. ④We came a week ago, since when the weather has been bad. 四、when 还可用作名词，前面常常用定冠词 the。 the when 表示事 件发生的时间,常常与 the where, the how 并列使用。 He told the police the when and the how of the accident. 他告 诉警察事故发生的时间及发生的原委。 ［巩固练习］ 1.

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.
