◆时间状语从句的考查要点
.时间状语从句的连接词：when，whil ( http: / / www.21cnjy.com )e，as，whenever，till，until，before，after，by the time，the first time，the last time，as soon as，once，the moment，each time，since，ever since，no sooner...than，hardly...when，the minute，immediately，directly，instantly，every time，next time
1．before在…之前,….才 We had sailed four days before we saw land.
还没来得及 Before I could get in a word, he had measured me.
（注：before引导的从句中不用否定式谓语）。
常用如下句型：
It will be long before...(得过好久才……)
It will not be long before...(过不了多久就……)
It was long before... (过了好久才……)
It was not long before... (过了不久就……)
It was two weeks before we met again.两周之后我们才见面。
注意判断before在状语从句中的含义：才；就；趁……没有；还没来得及；宁可……也不；不知不觉。
1. 判断下列各句中before的含义：
( )①We had sailed four days and four nights before we saw land.
( )②We hadn't run a mile before he felt tired.
( )③Please write it down before you forget it.
( )④Before I ( http: / / www.21cnjy.com ) could get in a word，he had measured me.
( )⑤She would die before she'd give in.
( )⑥Three months went by before we knew it.
【答案】1. ①才 ②就 ③趁……没有
④还没来得及 ⑤宁可……也不 ⑥不知不觉
2．since后面所用动词不同，该动词所表示动作持续时间的计算方法也不同。
It is two years since he joined the army.他参军两年了。
It is two years since he smoked.他戒烟两年了。
3．as，when，while用法一览表。
类别 作用 例句
as as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。 She came up as I was cooking.(同时)The runners started as the gun went off.(几乎同时)
when (at or during the tim ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 )e that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。 It was raining when we arrived.(指时间点)When we were at school，we went to the library every day.(在一段时间内)
while while意思是“当……的 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 )时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示a period of time时，两者可以互换。 Please don’t talk so loud while others are working.He fell asleep while/when reading.Strike while the iron is hot. (用as或when不可，这里的while意思是“趁……”)
技巧点拨： when
when的特殊用法是高考常考的一个重难 ( http: / / www.21cnjy.com )点,常用考点需要跟学生常常梳理1）be about to/ be going/ be just going to do/ be at the point of doing/had just done+ when 从句， 表示主句动作发生时，从句动作突然发生 2） It was +点/时刻+when 从句 3）when 还可以表示尽管、虽然 e.g. He stopped when he should have continued.
4.引导时间状语从句的连接词除上述外还有：
(1)till，not...until...，until
Don’t get off the bus until it has stopped.
He waited for his father until/till it was twelve o’clock.
(2) immediately/i ( http: / / www.21cnjy.com )nstantly/directly，the moment/minute/second/instant，as soon as，on/upon＋n./doing，hardly/scarcely...when...，no sooner...than...， 意为“一……就”
He made for the door directly he heard the knock.
The moment he saw his mother，he burst into tears.
We had hardly got/H ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 )ardly had we got into the country when it began to rain.
No sooner had he ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 )arrived/He had no sooner arrived than she started complaining.
完成下列句子：
他一到达车站，汽车就发动了。
__________(连词) he arrived at the station，the bus started.
＝________(连词) had he arrived at the station when the bus started.
＝________(连词) had he arrived at the station than the bus started.
＝________(副词) he arrived at the station，the bus started.
＝________(名词) he arrived at the station，the bus started.
＝________(介词) his arrival at the station，the bus started.
【答案】As soon as；Hard ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 )ly/Scarcely；No sooner；Immediately/Directly/Instantly；The moment/minute/second/instant；Upon/On
(4)each time，ever ( http: / / www.21cnjy.com )y time，next time, the last time, any time, all the time 等名词短语用来引导时间状语从句。
Every time I was in trouble, he would come to help me out.
Each time he came to my city，he would call on me.
几个极易混淆的时间状语从句：
It was +时间点+when…（当….的时候时间是….）
It was 5 am when we arrived at the village.
It was/will be+时间段+before…(没过…就／过了…才)
It was/will be two weeks before we met/meet again.
It is /has been +时间段+since…（自从…以来有…）
It is/has been 3 years since we last met.
突破点：一看be动词的时态，二看时间段还是时间点。2. 区别以下句型：
用before，that，since，when填空：
①It's three days ________ he returned home.
②It was three days________ he returned home.
③It will be three days________ he returns home.
④It was three days later ________ he returned home.
⑤It was three o'clock ________ he returned.
[注]解答此类题目关键有三 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 )点：首先要确定是不是强调句，当我们把it is/was以及连接词去掉时，剩余部分若能构成一个完整的句子，就是强调句，这时连词用that；否则，就要考虑它的句式特点。其次要看是时间段还是时间点。再次是连接词前后的时态。当确定为时间段时，连接词前后时态不一致，用since；时态一致，用before；当确定为时间点时，强调句就用that，否则就用when。

二让步状语从句
常见的引导词有：though, alt ( http: / / www.21cnjy.com )hough, as, even if / though, no matter +疑问词（不管，无论）与 疑问词+ever（不管）, whether…or…（不管…还是）,while等。如：
1）though &although
He is unhappy, thou ( http: / / www.21cnjy.com )gh/although he has a lot of money. (though 和although意思相同，置于句首句中皆可，不和but连用)
★though还可用作副词，意为”可是，然而“，置于句末。
He said he would come; he didn’t, though.
2)as或though引导让步状语从句倒装的情况
as让步状语从句中，会涉及到倒装的 ( http: / / www.21cnjy.com )问题，特别是as引导的让步状语从句是必须倒装的，这边可跟学生梳理as引导让步状语从句的几种倒装的情况： 1）将表语提前， 此处表语可以是名词或者形容词和副词：形容词/副词/名词+as+主语+be/系动词， 注意：名词提前不带冠词2）将实意动词（部分谓语动词）提前： 实意动词+as+主语+助动词/情态动词

Child as/though he is, he knows a lot about computers.

No matter how hard the work is，you’d better try to do it well.
Don’t trust him，no matter what/whatever he says.
All people, whethe ( http: / / www.21cnjy.com )r they are old or young, rich or poor, have been trying their best to help those in need since the disaster.
所有人，无论老幼贫富，灾难之后都竭尽全力帮助那些身处困境的人。
Whoever breaks the law, he will be punished.
=No matter who breaks the law, he will be punished.
注意区分：whoever, whatever, whomever, whichever还可以引导名词性从句。
Whoever breaks the law will be punished. (此时whoever=anyone who)
however和whatever引导状语从句的区别
however后接形容词或副词，相当于no matter how；而whatever后接名词，相当于no matter what。
用however，whatever填空：
①________ difficult it may be，you shouldn't give up.
________ difficulties you may come across，you shouldn't give up.
________ many difficulties you may come across，you shouldn't give up.
②You can dress ________ you like.
You can wear ________ you like.
【答案】①However；Whatever；However ②however；whatever

通常由副词、介词短语、动词不定式、分词等担当。

② We worked hard , from sunrise to sunset . (介词状短语)
