1、连词及状语从句状语从句一、状语从句的定义：状语从句是主从复合句中修饰主句中动词，形容词，副词等的从句，也叫做副词性从句。 状语从句一般分为时间、地点、条件、让步、比较、方式、目的、结果、原因九种状语从句 附：各类状语从句连接词（短语）一览表：时间when, while, as, as soon as, since, until, after, before条件if, unless原因as, because, since地点where目的so that, in order that结果so that, sothat, suchthat让步though, although, even if, ho
2、wever方式as 比较than, (not)asas, 二 二. 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 soon as（一就），once（一旦就）等。1. 连词：(1) when引导时间状语从句，表示主句的动作和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。He was working when I went in. 我进去时他正在工作。When she heard the news, she
3、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 music. 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”。John sings as he walks home. 约翰一边往家走一边唱歌。
4、(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，主句常用否定形式，not until意思为“直到才”。He didnt go to bed until he finished his homework. 他直到做完作业才睡觉。2.注意事项： (1) 时间状语
5、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。Ill stay here until you come back. 我会呆在这里，直到你回来。（2）引导词while, when, as的区别： 1）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：21教育网When he came in, his mother was cooking.When (While) we were at school, we went to
6、the library every day.2comWhile表示时间段,因此，while 从句的谓语动词要用延续性动词。如：Please dont talk so loud while others are working.【来源：21世纪教育网】2）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：【来源：21cnj*y.co*m】As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。三地点状语从句：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

8、e you come, wait for more time please.2.注意事项：（1.） because、since,as 语气强弱比较： because sinceas(2) because和so不能同在一个句子里。Because the book was expensive, I didnt buy it. (I 前不用so)五. 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。注意： (1) such. thatsucha(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
9、(2) so . thatso形容词副词.that从句so形容词a(an)单数可数名词that从句so+many/much/little/few +名词+that +从句He runs so fast that nobody can catch up with him.

10、 so fast that I couldnt follow him.He is such a lovely boy that we all like him.=He is so lovely a boy that we all like him.六、. 目的状语从句：目的状语从句在主句中表示目的。其连接词有：so（以便），so that（为了），in order that（为了）等，从句中多用情态动词can, will, may, should 等。例如：He got up very early so that he could catch the first train. 他起床很早以便于
