状语从句

状语从句的作用:

状语从句的种类:

状语从句的考点:

?各种状语从句的从属连词有哪些;

?同一种状语从句中从属连词的区别;

?同一个从属连词在多种状语从句中的运用。

一、时间状语从句:

引导词:When, whenever, as, while, before, after, until (till), since, as soon as, once

each/every time, next time, the first/…time, the moment, the minute, instantly, immediately, directly(一…就…), no sooner…than, hardly/scarcely…when

考查重点:

1)when的用法:was doing…when, be about to do… when“正在做

某事/正要做….突然发生另一件事”。

2.)几种特殊句型与强调结构的区别:

It is + 时刻+ when…

It is/has been + 段时 + since(谓语动词一般为过去时)…

It will be/was + 段时 + before (现在时/过去时).“过一段时间…才”

3).before的用法:

A:表“还未来得及…就…” B:表“过一段时间才…”,

4).until的用法:在not…until结构中,谓语用短暂性动词,“直到…才”;谓语为延续性动词,用until表“一直持续到…”。

5) no sooner…than,hardly/scarcely…when 刚……就

A. 时态:主句用过去完成时(had + pp)从句用一般过去时

B. 倒装: no sooner/hardly/scarcely放句首,主句要倒装She had no sooner arrived at the station than the train started to move.

No sooner had she arrived at the station than ….

He had hardly entered the hotel when it began to snow. Hardly had he entered the hotel when it began to snow

二、原因状语从句:

引导词:because, since, as, for, now( that), considering

(that), seeing (that)

考查重点:because, since, as, for

because—直接原因,非推断.语气最强.回答why

since –通常放句首.译为“既然”

as–不谈自明的原因,语气最弱.

for–放句中,对前面一句话的内容的补充说明。

三、地点状语从句:

引导词:where. Wherever。Where指“在某个地方”,wherever 指“无论哪里,在任何一个地方”,在使用时:一要注意两者的含义区别。二要注意状语从句和定语从句的区别。三要注意在状语从句中不可使用介词+which引导。出题者既考状语从句又考定语从句和状语从句的区别。还加入名词性从句这一干扰项。

四、目的状语从句和结果状语从句

引导词:in case, so that, in order that, for fear that。So that引导状语从句只能置于主句之后。In order that引导状语从句可放主句之前或之后。目的状语从句的谓语常含有can,could,may,might情态动词。这也是与结果状语从句的一个区别。引导结果状语从句的连词有:so that,so…that,such…that.结果状语放在主句之后。

注意:在so…that,such…that结构中一般成分齐全。这也是与as引导定语从句的区别。在so…as,such…as 这一结构中,as引导定语从句,在句中做成分。

五、条件状语从句:

引导词:if ,as/so long as, as far as,unless,in case (如果)

条件状语从句一般考查三点:

1)在条件状语从句中常用一般现在时表示一般将来时,用一般过去时表过去将来时。

2)if,unless,in case是考查重点。

3)when还可表条件,这一点不可忽视。意思是:既然,考虑到。如:

How can they learn anything when they spend all their spare time,watching television?他们把所有空闲的时间都用来看电视了,还能学到什么东西呢?

六、让步状语从句:

引导词:though /although“尽管”,even if /even ,though“即使”,no matter how(what,when,which,who,where),however(whatever,whenever,whichever,whoever,wherever), as“尽管”

1)although与though可互换,都可以与yet,still连用,但不能和but连用。

2)However引导让步状语从句时后紧跟形容词或副词。

3)While也可引导让步状语从句,这一点特容易被考生忽视。

4)Whatever修饰名词,“无论什么”,however修饰形容词、副词,“无论多么,无论怎么”。

5)even if/even though(即使)与as if/as though(好像)这两组学生容易混淆,也是出题者关注的对象,平时要记准含义。

七、比较状语从句和方式状语从句:

引导词:than / as—注意省略

as/like,as if/as though

The project was completed earlier than (it was) expected.

He worked as fast as a skilled worker (worked). Repeat this as often as (it) is necessary.

Then see a doctor as soon as (it is) possible.

Do you have to feed plants like you feed chickens? Do it like I tell you.
