(完整版)初中时间状语从句语法及练习
英语时间状语从句讲解(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.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。
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。
因为如果用正在进行时,它表示的就是一段时间而不是一个时间点了。
根据这一点,有的文章补充说:when 从句的动词大多是瞬时动词。
这种说法也可以参照。
实际上,when 从句也可以有其它的时态,但几乎也不用进行时,因为它也只是作为一个时间参照点。
例如:2. When he had finished his homework, he took a short rest.3. Why do you want a new job when you have got such a good one already?二、while 的用法相比于when 来说,while 从句的侧重点就不一样了。
while 从句的侧重点在于描述动作正在发生的状态,它的意思是:当while 事件正在发生的时候,另一件事如何如何。
所以,while 从句一般用的是正在进行时。
而另一件事的状态没有硬性的要求,根据具体情况而定。
例如:1. While my wife was reading the newspaper, I was watching TV.2. While Jim was mending his bike, Lin Tao came to see him.3. While they were talking, the bell rang. 正在他们谈话的时候,上课铃响了。

A. As当……的时候;B. Since 自从;C. Unless除非;D. Although尽管。
根据下文Jeff thought it was worth both the time and the money.可知上文是让步状语从句,这里用Although引导。
根据题意,故选D。
2. Lucy knew nothing about it _____ her sister told her.A.because B.until C.if D.since【答案】B【解析】试题分析:句意:露西直到她姐姐告诉她才知道这件事。
Because因为; until直到; if如果; since自从。
Not···until直到···才,是一个固定句型。

引导状语从句的连词叫做从属连词。
状语从句的位置可以在句首,也可以在句末。
放在句首时,从句后面常用逗号与主句隔开;放在句末时,从句前面往往不用逗号。
If it ' s fine tomorrow, I lw gilo with you.I will go with you if it ' s fine tomorrow.状语从句分类:1、时间状语从句2、地点状语从句3、原因状语从句4、目的状语从句5、结果状语从句6、条件状语从句7、让步状语从句8、比较状语从句9、方式状语从句时间状语从句从属连词:when, while, as, before, after, till/until, since, whenever, as soon as(就)⋯⋯时态:主将从现,主情从现,主祈从现、When/while/as (当⋯时候)区别:主句动作与从句动作发生的时间(同时/之前/之后);从句动词(延续性/瞬时性)1)When:when 引导时间状语从句时表示“当⋯⋯的时候”,when既可以指时间段也可指时间点,从句中既可用延续性动词又可用瞬间性动词,且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。
初中英语状语从句和练习题(含答案)
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。

例句:I will come to see you if I have time.我有,我就来看你。
三如果 if 条件句的是重复生和示要生的情景和事件,主从句大多用一般在。
如:If bears are in danger ,they attack people.区提醒if 既可以引条件状从句,表示“如果”,也可以引从句,表达“是否”。
