时间状语从句(初)-英语语法大全

时间状语从句(初)-英语语法大全

1英语时间状语从句(初)知识定位状语从句是指句子用作状语时,起副词作用的句子。

它可以修饰谓语、非谓语动词、定语、状语或整个句子。

时间状语从句表示时间发生的先后关系,和时态语态紧密相关,是初中阶段最基本也是最重要的一种。

连接词形式变化多样,在中考中占有一定的比重。

直接考查形式多以选择,句型转换,完型等呈现,在阅读和写作中也有广泛的应用。

知识梳理(一)when, while 和as 引导时间状语从句的用法一、when 的用法如果只从现象来看,when 从句用的最多的是一般过去时,而主句的时态没有限制,根据具体情况而定。

1. When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想。

2. When she came into my room, I was just reading a book. 她走进我房间时,我正在看书。

3. Were you writing when the teacher came in? 老师进来的时候,你在写信吗?4. Sorry, I was out when you called me. 对不起,你打电话来的时候我出去了。

5. He was on the point of leaving when someone knocked at the door. 他正要走,这时有人敲门。

6. I thought of it just when you opened your mouth. 就在你要说话的时候,我也想到了。

7. I had hardly[scarcely] closed my eyes when someone knocked at the door.我刚一闭上眼,就有人在敲门了。

由以上内容可知,when 从句的 A 事件,相当于另一个事件 B 发生的时间点。

也就是说,when 从句的重点不在动作本身发生的状态,而只是把它作为一个时间点,所以when 多数情况下用的是一般过去时,则不用正在进行时。

初中英语中考常考状语从句整理汇总(共9类)

中考英语常考状语从句1.时间状语从句When/while/as, since, as soon as, until/till, before, after,once, by the time, the minute/ the moment(一...就...), every/each time, whenever,...(1) When & while &as①When:表示“当...时”,后面跟时间点、时间段均可,因而从句的动词可以是非延续性动词(又叫短暂性动词)或延续性动词。

例如:He was watching TV when his mom came back.当他妈妈回来时,他正在看电视。

When his mom was cooking, he was watching TV.当他妈妈做饭的时候,他正在看电视。

②While:表示“当..时”,后面只能跟时间段,因而从句的动词也只能是延续性动词,且常为进行时态(现在进行时或过去进行时)。

例如:While his mom was cooking, he was watching TV.当他妈妈做饭的时候,他正在看电视。

③as:表示“一边...一边...”【注意】与while区分:当一个人同时进行两个动作时(即主从句的主语是同一个人时),只能用as。

还可表示“随着...”。

例如:Tom sings as he works. Tom一边唱歌一边工作。

As time went by, I learned how to be strong.随着时间的流逝,我学会了如何变得坚强。

(2) until & till (介词/连词)until:表示“直到...”,表示某个动作或状态一直持续到...为止。

例如:They waited until/till their mom came back.他们一直等到妈妈回来。

(主句谓语动词为延续性动词)“not...until”表示“直到...才”。

初中英语状语从句一、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。

We always sing as we walk.我们总是边走边唱。
