并列连词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.

我读了还不到半个钟头就听到外面有脚步声。

（b ）过去完成时与hardly 等连用时，when 也可以换成before .例如：

Hardly had I left before the trouble started.

我刚一离开麻烦就开始了。

4. 句型：when 引导状语从句时，主句可以是肯定句，也可以是疑问句形式，但when 连接两个并列分句时，其前的分句只能是肯定句，即只能是不带否定副词not 的分句。前文（3 ）（ a ）最后一个例句算是一个例外。试比较：

Mick was sleeping when they went in. （并列句）迈克正在睡觉，他们突然走了进来。

When they came in Mick was sleeping. （主从句）他们进来时迈克正在睡觉。

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.

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, when, yet以及not only…but also…, both…and…, neither…nor…, either…or…, as well as/as well/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。 2. or有时表示“否则”，前面的祈使句通常表示条件，后面的简单句表示结果。如： Hurry up or you will be late. 快点，否则你会晚的。 III．并列连词but、yet；for、so；when分别表示一种转折、因果、并列的关系，如： I have a pen but no pencil. 我有钢笔，但没有铅笔。 He is good at math for he studies harder than others. 他擅长数学因为他学习比别人努力。 He is ill so he can’t go to school today. 他病了所以今天不能去上学。 I was taking a walk along the street when a car came. 我正在沿街散步突然一辆车驶来。

When的用法

并列连词When及其句式请同学们看下列2006年的几道高考单项填空题：例1.I had just stepped out of the bathroom and was busily drying myself with a towel _______ I heard the steps. A. while B. when C. since D. after (06湖南卷) 例2.He was about halfway through his meal ______ a familiar voice came to his ears. A. why B. where C. when D. while （06辽宁卷）例3.I was still sleeping when the fire ______ and then it spread quickly. A. broke out B. put out C. came out D. got out 06广东卷）例4.I ____ along the street looking for a place to park when the accident ______. A. went, was occurring B. went, occurred C. was going, occurred D. was going, had occurred （06安徽卷）许多考生认为这些句子是包含时间状语从句的复合句，其实不然，这些句子里的when并不是引导一个时间状语从句来修饰另一分句的谓语，恰好相反，该句语意重心在后半句，主要是要表达后一分句中的谓语动词所表达的动作，而前一分句只是为这一动作的发生提供背景。when在这些句中意为and at that time或and then，它引导的是并列句。这种用法在人教版高中教材中并不鲜见，现略举数例，并

when的用法

when的用法 ①when是at or during the time that, 既指时间点,也可指一段时间； while是during the time that,只指一段时间,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词. ②when 说明从句的动作和主句的动作可以是同时,也可以是先后发生；while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生. ③由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时；如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导,如： a. When the teacher came in, we were talking. 当此句改变主从句的位置时,则为： While we were talking, the teacher came in. when和while的区别 ①when是at or during the time that, 既指时间点,也可指一段时间； while是during the time that,只指一段时间,因此when引导的时间状语从句中的动词可以是终止

When the teacher came in, we were talking. 当此句改变主从句的位置时,则为： While we were talking, the teacher came in. b. They were singing while we were dancing. ④when和while 还可作并列连词.when表示“在那时”；while表示“而,却”,表对照关系.如： a. The children were running to move the bag of rice when they heard the sound of a motor bike. 孩子们正要跑过去搬开那袋米,这时他们听到了摩托车的声音. b. He is strong while his brother is weak. 他长得很结实,而他弟弟却很瘦弱. 具体你可以参考这一段.
