1. 作为疑问副词，引导特殊疑问句，意为“什么时候；何时”。
（1 ）When will they come back？
（2 ）What time will they come back？
回答when 引导的从句，不一定指出具体的时间点。如回答句（ 1 ）可用tomorrow，next month 等。而回答what time 引导的问句，则必须说出具全的时间点，如at two o'clock，at five past ten 等。
2. 作连接副词，引导名词性从句或不定式，意为“什么时候”。从句使用陈述句语序，时态根据实际情况而定。
（1 ）I'd like to know when they will come. 我想知道他们什么时候来。（when 引导宾语从句）

day，moment，year 等。
（1 ）His mother died on the evening that he was born. 他母亲死于他出生的那晚。（2 ）I stay at home on the days that I am not busy. 在我不忙的时候，我就呆在家里。
B. 在某些含有“时间”的名词词组后面，由于该名词不表示时间，或整个名词词组已用
作连词，所以不用when 引导。如：the moment，the instant，the minute，the second 等等，意为“一……就……”，引导时间状语从句。
（1 ）The first time I went to China，I visited Beijing. 我第一次来中国就游览了北京。

5. 由when 等引导的状语从句，如果主语与主句的主语一致或是it ，谓语动词又含be 动词时，主语和be 动词常常被省略，就变成“ when + V-ing/ V-ed/ adj/ 介词词组”的结构。

when的用法总结大全
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.

连词的用法教案(一)(初中英语)
教学过程 一、复习预习 教师引导学生复习上节课所学的内容复习，（以提问、回顾的形式进行），针对上节课的作业进行讲评、订正、答疑，并通过简单的句子导入本节课所要学习的连词。 连词含义：连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。连词主要可分为两类：并列连词和从属连词。 二、知识讲解 知识点1：并列关系连词的用法 在句子中并列连词用来连接平行的词、词组和分句。常用的并列连词有：and，both…and,not only…but also,as well as，neither…nor等。 1. 【考查点】单个连词及固定搭配的用法。 如：They sat down and talked about something. 他们坐下来并且讨论一些事情。 She plays not only the piano, but (also) the guitar. 她不仅弹钢琴而且还弹吉他。 注意：not only… but also关联两个分句时，一个分句因有否定词not 而必须倒装。 Not only does he like reading stories, but also he can even write some. 他不仅喜欢读故事书，甚至能写一些。 2.【易错点】1) 并列结构中，or通常用于否定句，and用于肯定句。
2) 但有时and也可用于否定句。请注意其不同特点： There is no air or water in the moon. 在月球上没有空气和水。 There is no air and no water on the moon. 在月球上没有空气没有水。 在否定中并列结构用or 连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。 知识点2：表示选择关系的连词 1.【考查点】选择关系的连词及固定搭配 or意思为"或则"。either…or意思为"或者……或者……"or else/ otherwise 否则 如：Which do you prefer, tea, coffee, or juice ? 你喜欢哪一个，茶，咖啡还是果汁？ Either you or I am right. 你和我有一个是正确的。 Be silent, or else you will be kicked out. 保持沉默，否则你将会背开除。 I am tired, otherwise, I would play. 我很累，不然的话我就去玩了。 知识点3：表示转折或对比关系的连词 1.表示转折关系和对比关系的连词有but，while，yet，however等 2.【考查点】转折关系连词的用法 如：He is rich but unhappy. 他很富裕但不快乐。 Some people love cats, while others hate them. 有些人喜欢猫，而有些则讨厌他们。 She said she would be late, yet she arrived on time. 她说她将会迟到，然而他却准时到达了。 She does not like him, however, I like him. 她不喜欢他，但是我喜欢他。 They were not the bones of an animal, but (the bones) of a human being. 他们不是动物的骨头而是人类的。 注意：not 和but 后面的用词要遵循一致原则。 2.【易错点】but和however的区别。However后有逗号，but没有。 知识点4：表示因果关系的连词 1.【考查点】for因为，做并列连词使用时，是在对先行的句子补述原因或者理由， 以连接句子与句子，通常不置于句首。so, therefore 因此，then那么，因而。 如：He is absent today, for he is ill. 他今天缺席了因为他生病了。 He hurt his leg, so he couldn't play in the game. 他的腿受伤了，因此不能参加这个游戏。 知识点5：谓语动词单复数的判断 1.【考查点】句子有as well as,neither…or等连词时注意谓语动词的单复数。
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... She was just about to say something more when she noticed the sullen look on his face．她刚要再说些什么，却突然看到了他阴沉的脸色。 We were about to telephone you when your telegram arrived. 2．be (just) on the point of doing sth ... 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。
