whatever,whoever,whomever,whenever,wherever,(无论什么,无论谁,无论何时,无论在哪里)语气比what,who,when等强烈 。

△宾语从句(在复合句中作主句的宾语,放在动词,介词,某些adj.等后作宾语)

引导词:that (无任何意义,不充当任何成分,常省略)

(think,believe,suppose,expect等后接that引导宾从,形式上否定主句,意义上否定从句)

eg. The trouble is that we are short of money

△注意同从与定从的区别

介词+关系代词,介词+whom/which/whose+n.

关系副词when,where

注意:as引导非限制性定从常用于一些固定意义的表达

As is expected.

3.状语从句包括

(1)时间状语从句

连接词 when, while, as; before; after; since, ever since, until, till, as soon as, once, no sooner…than; hardly……when, scarcely…before(when),immediately, directly, instantly; the moment, the minute, each time, next time, the first/last time, soon after

△when 既可引导一个持续性动作,也可引导一个短暂性动作,可用于主句和从句动作同时发生或从句动作先于主句动作

while引导的动作必须是持续性的,强调某一段时间内,主从句动作同时发生,相当于during the time that……

as 引导的时间状语从句可用持续性动词,也可用非持续性动词,但它较强调主从句中的动作同时发生,也可用来说明两种正发展或变化的情况。 “随着”,表时间的推移。

eg. It was raining when she arrived home.

My mother was cooking while I was doing my homework

As I get older, I get more optimistic

△(主句)延续性动词(肯定式)+until/till从句(短语) “直到……才” 强调句型 It was not until … that …

not until 置于句首,主句要用部分倒装

△Since 引导时间状语从句,“自从……时”,主句要用完成时态。但时间的计算方式略有不同

since后若是终止性动词的过去式,则时间的起点应从该动作发生时算起。

since后若是延续性性动词的过去式,则时间的起点应从该动作结束时算起

在“It is + 一段时间 +since从句……”句型中,时间一律以since从句的动作完成时算起。

eg. Mr Li has been here since he came back

He hasn't been back at school since he was ill.

自从他病愈后一直没到学校来

I haven't heard from him since he lived here.

自从他不住在这儿以来,我就没有收到过他的来信。

It is three years since she was not in our class.

△ no sooner … than, hardly … when, scarcely……before/when 引导的时间状语从句表示“刚……就……”,“一……就……”,在这些结构中,主句动作先发生,用过去完成时, 从句用一般过去时,主句常用倒装语序,即把助动词had放在主语前面

eg. No sooner had he reached home than it began to rain.

Hardly/Scarcely had I entered the room when the phone rang.

(2)地点状语从句

连接词 where ,wherever

△ 地点状语从句有抽象条件的含义时,从句要在主句的前面。

eg . I will follow you wherever you go.

Where there is a will ,there is a way.

注意where引导的地点状语从句与where引导的定语从句的区别

eg. Go back where you came from. (从句前无先行词)

Go back to the village where you came from. (从句前有一个表地点的n作先行词)

(3)原因状语从句

连接词 because. since, as, for; now that(既然);seeing that(鉴于……),considering that (考虑到……;由于……)

△ because 所表示的原因含有较强的因果关系,专门回答用why 提出的问题,一般放在主句后面

since 语气次于because,表示稍加分析后推断出来的原因或是人们已知的原因。“既然,由于”,常置于句首。

as 语气最弱,多以既成的事实为理由,一般放在句首。用于因果关系十分明显的场合,也可置于主句后面。

eg It was because he was ill that he didn’t go with us

Since no one is against it ,let’s carry out the plan.

As he wasn't ready in time, we went without him.

We couldn't walk very fast as the street was quite dark.

for 表原因,属并列连词,不是说明直接原因,而是对某种情况加以推断,用于表示补充说明理由。

eg. .He must be ill ,for he is absent today

△.now that 用来说明一种新情况,然后加以推论,位于句首时,that可省略

eg. Now (that) everybody is here, Let's begin.

(4)目的状语从句

连接词/词组 so that(以便,为了),so(以便),in order that ,in case (以防,免除),for fear that(以防),lest(以免)

从句中谓语常含may, might, can, could, will, would等情态动词。

△当从句与主句主语一致时,可将从句变换为so as to, in order to 短语。lest 引导的从句中须用“should+动词原形”,表虚拟语气。

eg. I shall write it down lest I should forget.

(5)结果状语从句

连接词/词组 so(结果),(so)that(结果),so……that……(如此……以至于……),such……that……(如此……以至于……)

eg. Mr Smith had overslept so he was late for work.

My pen fell under my desk (so) that I couldn't see it.

△注意几个易混句型

so +adj./adv. + that从句

so +adj. +冠词 +名词单数+that从句

so +many/few/much/little + n +that从句

such + 冠词+adj.+名词单数 +that从句

such + adj. +不可数名词/名词复数

eg. The box is so heavy that I can't carry it .

She is so beautiful a girl that all the boys of our class like her.

There is so little water that you can't drink.

She is such a good girl that she can help you.

(6)条件状语从句

△.条件状语从句中通常用一般现在时表示将来时态。

“祈使句+and/or/or else/otherwise引导的结果句”句型中,祈使句在意义上相当于条件状语从句

注意:if引导非真实性条件句时,虚拟语气的使用。

(7)方式状语从句

连词/词组:as(像……一样,依照),just as ……so ……(像……,正如……,对于……),as if/though (仿佛……的,就像……似的)

eg. I'll do as I am told to.

Just as water is to fish, so air is to man.

空气对于人,正如水对于鱼一样。

He spoke as if he had been there before.

△.as if /though 引导的从句与事实相符,用陈述语气;与事实相反,用虚拟语气。

eg. The woman teacher hurriedly left the classroom as though she was angry.

Our teacher treats us as though we were her children.

(8)让步状语从句

连词:though/although (尽管,虽然) ever if/though(即使),

whoever/no matter who ,whatever no matter what, whichever/no matter which, whenever/no matter when, wherever/no matter where, however/no matter how, whether……or(not),as, while(尽管)

△.although 比though的语气重些,多用于正式文体,引导的从句常位于句首,但一般二词也可互换使用,都不可与but连用,可以和yet,still连用。

△.even if/though 常用以强调让步概念,会有退一步想的意思(有时用于虚拟语气)

eg. We'll make a trip even if the weather is bad.

Even if I were in your place, I wouldn't take the job.

△.as 引导让步状语从句,从句部分用倒装语序,句型为:

adj/adv/n(不带冠词)/动词原形 + as + 主+谓

(在这种倒装结构中,也可以用though,但不可用although.)

eg. Although the TV set is very dear, I still bought it

child as he is, the boy knows a lot.

Try as I might, I couldn't lift the stone.

Whether you believe it or not ,it is true.

No matter how difficult (it may be),we are determined to carry the research to the end.
