高中状语从句讲解+练习 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.

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: 13. ①由 if, unless 等引导的条件状语从句; 14. ②由 although, though, even if / though 等引导的让步状语从句; 15. ③由 when, while, as, before, after, until / till 等引导的时间状语从句;
16. 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。 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 probl em 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,人们都走出了 会议室。(=The meeting over,
