第42讲复合句一状语从句【复习目标】▲掌握状语从句的作用。

▲掌握状语从句的意义。

▲掌握各种不同类型的状语从句。

【课前准备】要求学生回顾引导状语从句的各种连词，并用不同的连词各造一个状语从句。

【知识要点】状语从句在句中作状语，修饰句中的动词、形容词或副词等。

状语从句巾从属连词作关联词，从属连词在从句屮不充当句子成分。

状语从句在主句之前，一般要用逗号分开，朗读时用升调。

状语从句在主句之后，一般不用逗号，朗读吋用降调。

状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点等类型。

1.时间状语从句⑴常用的连词有when, whi le, before,after, until (till),since , as soon as 等。

(2)吋间状语从句中一般不用将来时，若谈论将来的事情，往往用•一般现在吋代替，如:I'll g o on with th e work when I come back tomorrow./As soon as he finishes the work, he wil I come to se e me.⑶when和while都表示“当 .... 的时候”，但有区别。

when强调“特定时间”，如：There was a loud knock at the door when he was just fallin g asleep, whi le表示的时间是一段，而不是一点，如：While he was havi ng supper, h e heard some one knock at the door, while有时还有对比的含义，如：While I w as reading,he was writi ng.2.原因状语从句⑴常由because, since, as 引导。

(2>because表示直接的原因，着重点在从句，用于回答why,语气，最强。

I can't g o to school because I am ill.since 一般表示对方已知的，无须加以说明的既成事实的理由，全句中心在主句，语气比be cause 弱，常译为“既然”，如：Since y ou are ill,I'll go alon e.as表示十分明显的原因，一般说明因果关系，着重点在主句，语气较弱。

常译为“巾于”，如：As it is rainin g hard, we w on't go hiki ng.for是个并列连词，只能放在另一个并列分句后而，表示一种推理或解释，或用作附加说明，而不是指理由或原因，语气最弱，一般不放在句首，常译成“因为”，如:You h aven't met h im, for he d idn't come h ere.3.条件状语从句常由if(假如、如果｝No matter(不管｝來引导，如：No matter what he says, I won't believe hi m,如果主句是一般将来时，从句往往用一般现在时来表示将来，如：I'll go for a pic nic if it is fine.4.结果状语从句一般由so...t hat, such...that 引导，如:It's such a hea vy box that nobody can m oveit.The b ox is so hea vy that nobo dy can move it.5.目的状语从句往往由so that, i n order that 弓I 导，如：111 sp eak slowly s o that you c an understan dme.He set off early in order that he might be in time.6.比较状语从句常由as...a s, than, not as/so…as 等引导。

比较从句部分常是省略勾，如：I'm tai ler than he (is).Science is not as p opular as En glish.7.方式状语从句常用as 引导。

如：Y ou should do it as I tol d you.8.让步状语从句由though或al though等引导，但不能与but同时连用，如:Though it sn owed heavily ,they kept on working.9 .地点状语从句常用whe re, wherever 引导。

如：「II go where work is hard. 【典型例题解析】]列 1 The question was _______ d if ficult that nobody could answer [CD#3].A.very...themB.very...itC. so...them D . so...it解析因为句屮有that,所以前而用so,构成so ................ that从句，而qu estion足单数，用代词it,故选D。
