一、状语从句概说
1、在句中作状语用的从句叫状语从句（句子不缺任何成分）。
2、状语从句可以在句首，也可在句中或句末。
3、状语从句按其用途可有时间、地点、原因、目的、结果、让步、方式、比较等九种。
一: 时间状语从句（五类引导词）
1.从属连词：
when（当……时），while（在……期间），
as（当……，一边……一边……），
before（在……之前），after（在……之后），since（从……以来），till/until（直到），whenever（无论何时），
as soon as（一……就）once(一旦)等。
注意：在时间状语从句中，主将从现
难点逐个击破
1.before “在……之前”，
“还没来得及/还没有……就……，
趁着还没……就……，
不知不觉就……，

句型：肯才否就
It will be /was+一段时间+before “过多久才……”
It won't be /wasn't+一段时间+before
“用不了多久就 ...”
注意时态:

我没坐多久他就回来了。
He almost knocked me down before he saw me.
他几乎把我撞倒才看到我。

2、since的用法：
since表从过去某一时间或动作、事情起到目前为止，“自….以 来”
①、引导状语从句时，主句: sb has/have done（或现在完成进行时）+since从句过去时
I have written home four times since I came here.
I’ve been living here since I came to Beijing.
②、常用句型：It is (has been)…..+ since +一般过去时
It is five years since I began to learn English.

.
3.until 与 not until
until “直到...时”
“做某事直至某时"，主句动词必须是延续性动词
not ...until “直到...才”
"直至某时才做某事"。主句动词为延续性或非延续性都可以
I slept until midnight.
我一直睡到半夜时醒了。
She didn't arrive until 6 o'clock.
她直到6点才到。


4、as, when, while 的用法与区别：
when:
①引导状语从句，表示主句、从句的动作或状态同时、之前、之后发生。
When they arrived, it was already midnight.

When the clock struck eleven, all the lights went out.
从句的动作在主句之前发生,只能用when。
When he ran to the stop, the bus had gone.
从句动作在主句动作之后发生，只可用when



②、when = and then,作并列连词，when前通常有逗号。“这时…. 就在这时….“
I was wandering in the street, when suddenly
I caught sight of one of my old friends.


while
①、while意思是during the whole of the time that,指在一段时间里，所引导的从句中的动词是延续性的，“在….期间， 在….之时”
She visited a lot of places while she stayed in U.S.
He felt asleep while he was watching TV.
②、while可用作并列连词，连接两个分句，表对比，“而….”
My son likes to watch boxing games while I would rather listen to music.
as
表两个动作交替进行或同时完成，
“一边…一边…”或“随着….”
"随时间推移"用as,不用when或while。　

As he grew older ,he lost interest in everyting except gardening.
As time went on, it's getting warmer and warmer.
用when, while或as 填空:
_______________ we were talking, Mr Smiths came in.
_____ they came home, I was cooking dinner.
I was about to go to bed _______ I heard someone knock at t the door.
4. ________ we were watching TV, he was studying.
