高中英语状语从句讲解及练习含答案

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：Naturally,ourgrandparentswerepleasedtogetourphonecall.(副词)We

workedhard,from

sunrisetosunset.(介词状短语)Tohelpmydisabledaunt,Ispendanhourworkinginherhouseevery

day.(不定式)Seenfroma

distance,thefarmhouse

lookeddeserted

.(过去分词)IknowhowtolightacampfirebecauseIhaddoneitbefore

.（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和特殊的连接词即考点。现分别列举如下:1．

时间状语从句常用引导词：when,as,while,assoonas,while,before,

it；②从句主要动词是

be

的某种形式。从句中的主语和b

e

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,

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

yououtof

thedifficulty.如果可能的话,他会帮你摆脱困境。Youmust

attendthemeetingunless

(itis)inconvenienttoyou.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:连词+形容词As

(hewas)

young,he

learnedhow

toridea

bike.他小时候就学会了骑自行车。Whenever(she

is)free,sheoftengoesshopping.她有空就去逛商店。Work

hardwhen(you

are)young,oryou'll

regret.少壮不努力,老大徒伤悲。连词+名词While(hewas)a

youngboy,he

wasalwaysreadytohelp

others.他在孩提时代就乐于助人。Although(hewas)a

than(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He

if

(he

were)

to

something.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Shelooked

anxiousasthough(she

was)introuble.她看上去很焦急,好像遇到了麻烦。He

hadmasteredtheEnglish

languagebefore

(hewas)

inthe

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:Whenthemeetingwasover,allthepeoplewentoutofthemeeting-room.当会议结束时,人们都走出了会议室。(=The
