二、时间状语从句1.主句和从句同时发生，这类从句由从属连词when, while, as引导。

He was hungry when he came home.I was crying while everyone was laughing.As I walked out, he walked in.as, when, while, 的区别①as强调从句的动作与主句动作同时发生及持续，具有at the same time的意思他继续往下谈的时候，越来越兴奋。

as还可以表示一边……一边……，强调从句和主句中两个动作交替进行或同步进行。

他们边走边聊。

as还有“随着”的含义随着春天的到来，天气暖和起来。

②when强调动作点的特定时间，具有at the time that的意思当老师走进来的时候，我们都站起来了。

③while表示较长的期间，具有during the time that的意思当我在这的时候，我很安全。

2.主句发生在从句之前，这类从句由从属连词before, until引导,before意为“在---之前”until 在肯定句中意为“直到---为止”，在否定句中意为“直到---才”。

从句既可置于主句前，也可置于主句之后。

回家之前我必须干完所有的活。

我们将一直等到他回来。

他直到晚上11点才回家。

3.主句发生在从句之后，这类从句由从属连词after引导，意为“在---之后”。

从句既可置于主句前，也可置于主句之后。

初中英语状语从句和练习题(含答案)

状语从句的分类一、时间状语从句时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since 等。

时间状语从句的引导词所表示的意思不尽相同，要注意把握不同引导词所表示的不同时间关系，以及它在具体句子中对应的时态、语态等问题。

注意： as（在⋯⋯时候，因为）， since （自从，因为），它们可以引导时间从句，并强调主句和从句的动作同事发生。

并且 while 有时还可以表示对比。

例如：（ 1）While my mother was reading the newspaper, I was watching TV.（read 是延续性的动词， read 和 watch 同事发生）I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。

（对比）（2） when（当⋯⋯的时候），引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。

从句动作可与主语动作同事发生，也可在其后发生。

I was reading a book when she came into my room.（come 是瞬间动词，只能用 when 引导，不能用 while）I often missed my home when（while） I lived in NewYork. （ live 是延续性动词， when 可用while 代替）（ 3）when 和 while 的区别还在于： while 引导的时间状语从句多用于进行时态，而 when 引导的时间状语从句多用于一般时态。

While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。

（ 4）as 译作“一边⋯⋯一边”、“随着⋯⋯”，侧重主句和从句的动作同时发生。

有时可与when， while 通用。

初中英语状语从句讲解、练习与答案

初中英语状语从句讲解、练习与答案初中英语状语从句讲解、练习与答案1、时间状语从句(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。

例如：It was raining hard（rain hard 下大雨） whengot to school yesterday、While he was doing his homework, the telephone rang、As he walked along（沿着走） the lake, he sang happily、He had learned a little Chinese before he came to China、After he finished middle school, hewent to work in a factory、(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。

时间状语从句讲解和练习(答案)

时间状语从句用句子表达一件事情或一个行为发生的时间，这个句子就叫时间状语从句。

时间状语从句根据其所表示的时间不同，所使用的连词也不同。

下面我们一起来看一下几个常见的时间状语从句：1．when引导的从句：表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。

例如：I was going out when a visitor came. (动词动作同时发生。

)我正要出门，有客人来访。

I shall tell her the good news when she comes.她来时，我将告诉她这个好消息。

小试牛刀：I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get)2．while 引导的从句：表示“当……过程中”，强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。

由于while从句表示一个持续的行为，所以从句中要用持续性动词，并且持续性动词常用进行时态。

例如：Keep an eye on my little sister while I am away.我不在时，请照看一下我的小妹妹。

While we were watching TV, Jim came in. 我们看电视的时候，Jim进来了。

小试牛刀：It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music.3．as引导的时间状语从句：表示“当……的时候；一边……一边……；随着……”，其从句的主语与主句的主语往往是同一人或物。

初二状语从句练习50题(答案解析)

初二状语从句练习50题(答案解析)1. I was reading a book ____ my mother came back home.A. whenB. whileC. asD. since答案解析：A。

本题考查时间状语从句。

when引导的时间状语从句，既可以表示在某一时刻，也可以表示在某一时间段，从句中的动词可以是短暂性动词也可以是延续性动词。

在这个句子中，“my mother came back home”是短暂性动作，所以用when。

while引导时间状语从句时，从句中的动词必须是延续性动词。

as表示“一边一边”或者“随着”，在这里不符合语境。

since表示“自从”，引导原因状语从句或者时间状语从句（主句用现在完成时），这里也不符合语境。

2. We will go to the park ____ it doesn't rain tomorrow.A. ifB. whenC. asD. since答案解析：A。

这是一个条件状语从句，这里表示“如果明天不下雨，我们就去公园”。

if引导条件状语从句，遵循“主将从现”的原则，即主句用一般将来时，从句用一般现在时。

when引导时间状语从句，不符合句子逻辑。

as表示“当的时候”或者“由于”，在这里不合适。

since表示“自从”或者“既然”，也不符合语境。

3. ____ I got up this morning, I found my pet dog under my bed.A. WhenB. WhileC. AsD. Since答案解析：A。

when引导时间状语从句，表示“当我今天早上起床的时候”，强调某个瞬间动作发生时另一个动作也同时发生。

while 引导的从句中的动词应为延续性动词，got up是短暂性动词，所以不选while。

as有“随着”或者“一边一边”的意思，在这里不符合语境。

since表示“自从”或者“既然”，不符合题意。
