1、 状语从句小结在复合句中,用作状语的从句叫做状语从句。状语从句由从属连词引导，与主句连接，位于句首时，与主句间用逗号隔开；位于句末时一般不用逗号。状语从句根据其意思和用途可分为时间、原因、条件、让步、结果、目的、比较、方式和地点等类型。一、 时间状语从句1、 由 when、 while、 as引导，表示“当.时”Eg: I will tell him the news when he comes back. 等他回来我要告诉他这个消息。 I started my homework when he left. 他走了之后，我才开始做作业。The doorbell rang when I was
2、cooking. 门铃响的时候，我正在做饭。I was cooking when the doorbell rang . 在我做饭的时候，门铃突然响了。The phone rang while we were watching TV. 当时我们正在看电视，门铃突然响了。注意when 和while 的区别：when的意思相当于at that time (在.时刻)， when 引导的从句既可用瞬间性动词，表示某一时刻的动作；也可用延续性动词（此时从句常用过去进行时态）。While的意思相当于during that time(在期间)，表示某一段时间内发生的动作，因此while 引导的从句常用延续
3、性动词。 Eg: I was doing my homework when my mother came in. She was helping Jack with his English while Linda was watching TV.2、 由until或not.until引导，如果主句的谓语动词为延续性动词且为肯定形式，则until译为“到.时候为止”；如果主句的谓语动词为非延续性动词且为否定形式， not .until 则译为“直到才”Eg: I read the book until he came back. 我读书一直读到他回来。 I didnt go to bed unt
4、il my mother came back. 我妈妈回来之后我才睡觉。3、 由as soon as、the minute、the second或the moment引导，译为“一就.”，表示在从句动作发生之后不久，主句动作紧接着就发生了。Eg: We will leave as soon as it stops raining.雨一停，我们就离开。 It began to rain the moment I arrived home.我刚到家，天就开始下起雨来。 The minute I sat down in front of the TV, my mother came over. 我刚
5、坐在电视机前，我妈妈就过来了。4、 由before引导，表示“在之前”5、 由after引导，表示“在之后”6、 由since引导，表示“自从.、自从.以来”，主句常用一般现在时或现在完成时态，而since从句常用一般过去时态。 Eg: He has been in Shanghai since he was born. 自他出生以来，他一直住在上海。 John has looked for her mother since she left two years ago. 自从妈妈两年前离开，John一直在寻找她。一、 条件状语从句1、 由if引导，译为“如果.”Eg: If winter c
6、omes, can spring be far behind? 冬天来了，春天还会远吗？ Anything is possible if you work hard.如果你努力，一切皆有可能。2、 由unless引导，译为“如果不，除非.”Eg: You can never know whats possible unless you try to make it happen. 你可能永不知道什么是可能的除非你想让他发生。 We cant be successful unless we keep on working hard. 如果我们不继续努力， 我们不会取得成功3、 由as long
7、as 引导，译为“只要.”Eg:You will succeed as long as you work hard.注意：在时间和条件状语从句中，如果主句是一般将来时，从句要用一般现在时表将来，即“主将从现”二、 结果状语从句1、 由so/such.that引导，译为“如此.以至于Eg: He got up so late that he missed the first bus. 他起得太晚了，结果错过了第一趟公交。 Its so hot outside that nobody wants to go outside. 外面太热以至于没人想出去。2、 易错点：So.that与such.tha
8、t 的结构，用法区别：So +形容词/副词+that.He runs so fast that nobody can catch him.So+形容词+a/an+可数名词单数+that当名词前有表示数量的many/ few/ much/little(少的)修饰时，用so 不用such,即So+ many/few+可数名词复数+that. 或者 so+ much/little +不可数名词+that. such a/an+形容词+可数名词单数+that such+形容词+可数名词复数/不可数名词+that.

9、 very much.= She is such a lovely girl that we love her very much. 她是如此可爱的一个女孩，以至于我们都喜欢她。 We have so much time that we can finish the work well. 我们有如此多的时间，以至于我们能很好地完成工作。三、 目的状语从句由so、 so that、in order that 引导，译为“因此，以便，为了.”四、 原因状语从句由because、 as 、since、 for 等连词引导，译为“因为.”五、 让步状语从句由though、 although、 even
