1、中考英语语法专题复习：状语从句的用法【用法讲解】考试要求：状语从句概念：用一个句子(从句)来作另一个句子(主句)的状语，用作状语的句子就叫作状语从句。作什么样的状语就叫什么类型的状语从句。引导状语从句的连接词是从属连词，状语从句可以在句首，也可以在句尾。中考主要考查状语从句的类型有：时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句及比较状语从句等。1.时间状语从句：时间状语从句在主句中表示时间，常用连接词有：when（当时），while（当时），as（当时），before（在之前），after（在之后），since（自从），notuntil（直到 才），as

2、soon as（一就），once（一旦 就）等。例如：I didnt go to bed until I finished my homework.我直到做完作业才去睡觉。I can listen to the radio while I work.我可以边听收音机边工作。(1)时间状语从句中，一般要用一般现在时代替一般将来时，一般过去时代替过去将来时。例如：I will telephone you when he comes.他来时，我会给你打电话。I ll stay here until you come back.我会呆在这里，直到你回来。(2)when引导时间状语从句，表示主句的动作和

3、从句的动作同时或先后发生，从句的谓语可以是延续性动词，也可以是瞬间动词。例如：He was working when I went in.我进去时他正在工作。When she heard the news,she began to cry.她听到这个消息，她哭了起来。(3)while 引导的状语从句中常用延续性动词或表示状态的动词，意思是“在期间”。while 还可以表示两者之间的对比关系。They rushed in while we were singing.我们唱歌时，他们冲进来。I like playing football,while Tom likes listening to m

4、usic.我喜欢踢足球，而汤姆喜欢听音乐。(4)as引导状语从句，强调同时发生，不分先后。可以译成“随着”或“一边 一边”。例如：John sings as he walks home.约翰一边往家走一边唱歌。(5)since引导状语从句，主句常用现在完成时，从句常用一般过去时。We have been friends since we met in Beijing.自从我们在北京遇到就一直是朋友。It has been six years since she left school.自从她毕业已经有六年了。(6)until/till 引导时间状语从句，当主句的谓语动词是瞬间动词时，主句常用否

5、定形式，notuntil 意思为“直到才”。He didn t go to bed until he finished his homework.他直到做完作业才睡觉。2地点状语从句：地点状语从句在主句中表示地点。其连接词有where（哪里），wherever（无论哪里）等。例如：Put it where you find it.把它放在原来的地方。You can sit wherever you like.你喜欢坐在哪里就坐在哪里。3.原因状语从句：原因状语从句在主句中表示原因或者理由。其连接词有：because（因为），as（因为），since（既然）等。例如：I often eat ca

6、rrots because they are good for my health.我经常吃胡萝卜是因为对我的身体有好处。As I dont know the way,I had to ask the policeman.由于我不知道路，所以我不得不问警察。(1)because表示因果关系语气最强，常用来回答why 提出的问题。I didnt tell them because they were too young.我没有告诉他们，因为他们太小。(2)because和 so不能同在一个句子里。Because the book was expensive,I didnt buy it.(I 前

7、不用 so)4.结果状语从句：结果状语从句在主句中表示结果。其连接词有：sothat （如此 以至于），such that（如此以至于）等。例如：It s such a good chance that you cant miss it.这次机会如此好，你不能失去它。注意：sothat 和 such that 都可以引导结果状语从句，注意so和 such后面所接的词不同。(1)such.that such a(an)形容词单数可数名词that从句such 形容词复数名词/不可数名词 that 从句例如：He was such an honest man that he was praised

8、by the teacher.他非常诚实，因而受到了老师的表扬。They are such interesting novels that I want to read them once again.这些小说非常有趣，我想再读一遍。(2)但是如果名词前由many、much、few、little（少）等词修饰，则用so。例如：He had so many falls that he was black and blue all over.他摔了很多跤，以至于全身上下青一块，紫一块的。(3)so.that so形容词副词.that 从句so形容词 a(an)单数可数名词 that 从句例如：He

28、开始发生，故选择C。8.A。在时间、条件状语从句中，用一般现在时表将来意义。9.A。在英语里，有一些非延续性的动词，他们只是一瞬间就结束的动作，如：come，go，arrive，reach，see，hear，close，leave，begin，start，lose，buy，fall，join，die，get up等，用 It is since 的句型来表达目前存在的一种状态。故正确答案为 A。10.B。由 while 引导的从句表示某个动作还在进行的同时，另一个动作也在进行之中。故正确答案为B。11.B。sothat 意为“如此以至于”，表示结果，故正确答案为B。12.B。在 not unti

33、s do as the teachers say.学生们按照老师说的去做。比较状语从句：The work isnt as easy as I thought.这项工作比我想象得难。【辨析】易混引导词 while,when,as的区别：when既可以指“时间点”,与瞬间动词连用，也可以指“时间段”，与延续性动词连用（=while）。如：When he came in,his mother was cooking.When(While)we were at school,we went to the library every day.While 表示时间段,因此，while 从句的谓语动词要用延

34、续性动词。如：Please don t talk so loud while others are working.As 与 when 用法相似，但着重强调主句动作与从句动作同时发生，有“随着”或“一边一边”之意。如：As you get older,you get more knowledge.随着年龄的增长，你获得的知识就越多。2because,as,since 的区别：Because用于表示直接原因,回答 why 提出的问题，语气最强；As 用于说明原因,着重点在主句，常译成“由于”；since表示显然的或已知的理由或事实，常译成“既然”。如：Water is very importan
