6、要用逗号和主句隔开。分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。状语从句的概述甭管是啥状语从句，都长一个德性：但不同的状语从句，有不同的御用连词。时间状语从句引导词：when,while,as,before,after,since as soon as,till,until 时间状语从句 这三胞胎，都有“当时”的意思，表示两件事情几乎同时发生。但用法上有一丢丢差别时间状语从句时间状语从句当连词后面的事能够持续一段时间时，when,while,as都可以上。His phone rang when/while

7、/as he was sleeping.当他还在睡觉，铃声响了。时间状语从句当连词后面的事，是一个短暂的动作时，则只能用when或as。His phone rang when/as he opened his eyes.当他睁开眼时，铃声响了。当连词后面是这些事时，则只能用when。时间状语从句He sleeps when it snows.每当下雪天，他就睡觉。He died when he was 15.当他15岁时，他翘辫子了。此外，这三胞胎也各具特色。时间状语从句He was sleeping when the phone rang.他正睡着觉，这时手机铃声响了。时间状语从句He li

8、kes sleeping while she likes eating.他喜欢睡觉，而她喜欢吃。时间状语从句He snored as he slept.他边睡觉边打呼噜。As the sun rose,the fog disapperaed.随着太阳升起，大雾消去。时间状语从句We clean the classroom before we leave school every day.After you use plastic bags,you mustnt throw them.I have worked for this company since I graduated.时间状语从句I

9、t was ten minutes before he slept.10分钟后，他才开始睡觉。只有当前面是一段时间时，before和since才会让人发懵。It was ten minutes since he had slept.他已经睡了10分钟了。时间状语从句till、until表示“直到”的意思，他告诉咱们He slept until/till the bell rang.他一直睡到铃声响起。时间状语从句变成nottill/until告诉咱们He didnt sleep until/till the bell rang.直到铃声响起，他才睡觉。时间状语从句He opened his e

10、yes as soon as the phone rang.铃声一响，他就睁开了眼。从句一发生，从句就跟着发生as soon as时间状语从句I will tell him about it as soon as he comes back.铃声一响，他就睁开了眼。主从句时态通常是主将从现；类似还有the minute,the moment等。as soon as时间状语从句这么多时间连词，想不懵逼，就得让语法变语感，可不就得这么办。来，交作业了！习题演练1.It was quiet _ those big trucks started coming through the town.A.be

21、常带有情态动词。目的状语从句Lets luchuan in order that/so that we could find the answer to life.为了找到人生的答案，咱们去撸串吧。它们都有“以便”“为了”的意思，1.so that，in order that目的状语从句Lets luchuan in order to/so as to find the answer to life.为了找到人生的答案，咱们去撸串吧。这俩由so that和in order that简化而来，后面一般直接跟动词。2.so as to，in order to习题演练 (A)1.Read it al
