状语从句讲解和练习
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,ourgrandparentswerepleasedtoget
ourphonecall.（副词）
2.Weworkedhard,fromsunrisetosunset.（介词状短语）
3.Tohelpmydisabledaunt,Ispendanhourworkinginherhouseeveryday.（不定式）
4.Seenfromadistance,thefarmhouselooked
deserted.（过去分词）
5.IknowhowtolightacampfirebecauseIhaddoneitbefore.（原因状语从句）
状语的位置比较灵敏，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。
大凡可分为九大类，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例外状语从句的常用连接词
和分外的连接词即考点。
现分别列举如下:
1．时间状语从句
常用引导词：

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（themuseumis）completed,themuseumwillbeopentothepublicnextyear.
He’llgototheseasideforhisholidayif（itis）possible.另外，比较状语从句经常省略。
例如：
I’mtallerthanhe（istall）.
Thehigherthetemperature（is）,thegreaterthepressure（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,evenif/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,asif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（itis）possible,hewillhelpyououtofthedifficulty.如果可能的话,他会帮你摆脱困境。
Youmustattendthemeetingunless（itis）inconvenienttoyou.除非情况对你来说不便当,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（hewas）young,helearnedhowtorideabike.他小时候就学会了骑自行车。
Whenever（sheis）free,sheoftengoesshopping.她有空就去逛商店。
Workhardwhen（youare）young,oryou“llregret.新秀不努力,老大徒伤悲。
b.连词+名词
While（hewas）ayoungboy,hewasalwaysreadytohelpothers.他在孩提时代就乐于助人。
Although（hewas）afarmer,nowheisafamousdirector.尽管他曾是个农民,而现在是位出名的导演了。
c.连词+现在分词
As（shewas）walkingalongtheriverbank,shewassingingapopsong.她沿着河堤边走边唱着流行歌曲。
Although（heis）doinghisbestinmathsthesedays,hehasstillgotnogoodmarks.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
Hewon“tgotherewithusunless（heis）invited.除非受到邀请,否则他不会和我们一道去那里。
Theconcertwasagreatsuccessthan（itwas）expected.这场音乐会出乎意料地取得了巨大成功。
e.连词+不定式
Hestoodupasif（hewere）tosaysomething.当时他站起来好像要说什么。
Hewouldn“tsolvetheproblemevenif（hewere）totakecharge.即使他来负责,他也解决不了这个问题。
f.连词+介词短语
Shelookedanxiousasthough（shewas）introuble.她看上去很焦灼,好像遇到了麻烦。
HehadmasteredtheEnglishlanguagebefore（hewas）intheUSA.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:
Whenthemeetingwasover,allthepeoplewentoutofthemeeting-room.当会议结束时,人们都走出了会议室。
（=Themeetingover,
