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.
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,人们都走出了会议室.(=The meeting over,
