完整高中状语从句讲解及练习

状语从句

状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如：

1. Naturally , our grandparents were pleased to get our phone call . (副词)

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

3. To help my disabled aunt , I spend an hour working in her house every day . (不

定式)

4. Seen from a distance , the farmhouse looked deserted . (过去分词)

5. I know how to light a camp fire because I had done it before .（原因状语从句）状语的位置比较灵活，可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置。

状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词

10. 状语从句的简化

状语从句的省略

状语从句同时具备下列两个条件:①主句和从句的主语一致，或从句主语为it；②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。例如：

When ( the museum is ) completed , the museum will be open to the public next year .

He'll go to the seaside for his holiday if (it is ) possible.

另外，比较状语从句经常省略。例如：

I'm taller than he (is tall ).

The higher the temperature (is), the greater the pressure (is ).

就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行简化。状语从句的简化现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。

状语从句的简化现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句。下面针对这五种情形作一归纳。

(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:

If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境。

You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议。

(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:

a.连词+形容词

As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车。

Whenever (she is) free, she often goes shopping.她有空就去逛商店。

Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲。

b.连词+名词

While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人。Although (he was) a farmer, now he is a famous director.尽管他曾是个农民,而现在是位著名的导演了。

c.连词+现在分词

As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行

歌曲。

Although (he is) doing his best in maths these days, he has still got no good marks.尽管近来他一直在学数学,但他仍然没有取得好成绩。

d.连词+过去分词

He won't go there with us unless (he is) invited.除非受到邀请,否则他不会和我们一道去那里。

The concert was a great success than (it was) expected.这场音乐会出乎意料地取得了巨大成功。

3

e.连词+不定式

He stood up as if (he were) to say something.当时他站起来好像要说什么。He wouldn't solve the problem even if (he were) to take charge.即使他来负责,他也解决不了这个问题。f. 连词+介词短语She looked anxious as though (she was) in trouble.她看上去很焦急,好像遇到了麻烦。

He had mastered the English language before (he was) in the USA.他到美国之前就懂英语了。

注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达。例如:

When the meeting was over, all the people went out of the meeting-room.当会议结束时,over, meeting 人们都走出了会议室。(=The

高中英语状语从句讲解汇总

高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。
