状语从句考点归纳

一、基本状语从句从属连词的考查(对着提纲自己先回忆)

时间状语从句:1连词when, while, as的异同;

2连词before的含义(容易与一些句型混淆, 在草稿纸上写出);

3 until和till的异同;not until句型的倒装问题;主句的肯定与否定;

4弄清since引导的时间状语从句中谓语动词是状态/持续性动词还是终止性动

词;

区分It be …since/ before/ when/ that… 句型;

5表示“一……就……”的四类从属连词;

6 by “到……为止”引导时间状语, 注意主句的时态;

7 time短语可引导时间状语从句:

every/ each time, (the) next/ last time, by the time, the first time

等;

区分the first time和for the first time;

the first/ second / third time作表语后面接定语从句时,注意定语从句的

时态。

地点状语从句:1区分where与wherever;

2区分where引导的地点状语从句,定语从句与名词性从句;

原因状语从句:1连词because, since,as, for的区别;

2其他可引导原因状语从句的词(组);★★(在草稿纸上写出)

3区分because与because of。

条件状语从句:1区分if与unless除非/如果不(有时可换成if…not);

2区分only if(只有)与 if only(要是…就好了; 只要);

3 as/so long as只要;

4其他可引导条件状语从句的词(组)。★★(在草稿纸上写出)

让步状语从句:1连词although, though, as, while, when的区别;

2 though/ although 与even though/ even if的区别;

3 whether…or… (不论/不管……还是……)

whether …or not(不管/不论是否);

4“疑问词+ever”与“no matter +疑问词”的异同;

5还有些介词短语意为“尽管”。

目的状语从句:1 in order that与so that在句中的位置;

2引导词in case(免得/以防万一)与for fear that(担心/以防万一)。

结果状语从句:1区分so…that与such…that (口语中that可省略);

2区分结果状语从句与定语从句so/ such…that与so/ such…as;

3连词还有so that,with the result that。

比较状语从句:1 no more…than(不比……更) 和more…than(与其说…不如说);

2 as…as和not so (as)…as;

3 “the+比较级…, the+比较级”的时态。

方式状语从句:1 as(像、如同、按照); just as正如、恰似; (just) the same as和……

一样;

2 as it is/ was;as they are/ were 按照原来/现在的样子(句末)

3 A is to B what C is to B A对B而言正如C对D一样

4 as if, as though 有时用虚拟语气,有时不用虚拟语气

5 as if / as though 状语从句也可以用省略形式.

二、状语从句中的省略见省略

如状语从句的主语与主句的主语一致(或从句的主语是it),且从句谓语中又包含be,则从

主语和be动词可省Don’t talk while (you are) eating.

He looked around the room as if (he was) looking for something.

When (he was) asked how he gained first place, he suddenly became cheerful.

is)possible一有可能就

如果有需要if any 如果有

(现在分词或过去分词短语作定语,可以理解为是定语从句中将关系代词作的主语和be动词省略) Do you know the man (who is) sitting under the tree.

Is there anything (that has been) planned for tonight?

三、状语从句中时态的考查见时态

1在时间,条件状语从句中用一般现在时代替一般将来时, 现在完成时代替将来完成时when/ if 也可引导名词性从句该用将来时态仍用将来时态

时间状语的引导词有when, while, after, before, as soon as, not…until, once, by;

条件状语的引导词有if, unless

I don’t know if/ when he will come back. 我不知道他是否/什么时候回来。(if, when引导宾语从句)

If/ when he comes back, I’ll tell him.如果他回来/当他回来的时候,我会告诉他。

(if引导条件状语从句,when引导时间状语从句) If you will(愿意) wait here for half an hour, I will let you see him.

I will go to bed as soon as the work has been finished.

① We will go to the park____ tomorrow.

A if it not rains

B if it won’t rain

C unless it rains

D unless it will rain

② What will you do while your parents____ for the holiday ?

A. will be away

B. are away

C. leave

D. will leave

2 “The +比较级…, the+比较级….”结构,前面的句子相当于条件状语从句,用一般现

在时代替一般将来时 The harder you work at your lessons, the less difficult you

will find them.

3祈使句+and (then)/ or/ or else/ otherwise+陈述句(用一般将来时)相当于含有条件状语从句的主从复合句。 If you don’t hurry up, you will be late=

Hurry up, or else/ otherwise you’ll be late.= Hurry up (,) and (then) you won’t

(Say)A word more, and we’ll drive you

①Try the new cleaner. Just a few minutes every day—that’s all it takes—_____

you could have shining floors and furniture. A. and B. but C. or D.

so

②It’s really very dangerous. One more step, ___ the baby will fall into the well.

A. or

B. so

C. and

D. but

③Another chance, ____ I will do it better. A. or B. so C. and D. but

四、状语从句中的倒装见倒装

1 no sooner…than…/hardly/ scarcely…when…句型中hardly/ scarcely位于句首时, 主句要部分倒装且常用过去完成时

2 as引导让步状语从句必须用异常语序(though引导让步状语从句可用异常语序)

把表语或状语提前。句首名词不带冠词。

如实义动词有宾语和状语,随实义动词一起放在主语之前。

3 so/ such…that…引导的结果状语从句中,如so/such在句首,前面用部分倒装语序。

4 if虚拟句,如有had,should,were 这三个词,在正式或书面语言中可将if省略,再倒装。
