1、精选优质文档-倾情为你奉上状语从句在复合句中作状语，位置灵活。状语从句可分为时间状语从句，目的状语从句，条件状语从句，让步状语从句，地点状语从句，原因状语从句，方式状语从句，结果状语从句。（一） 时间状语从句1. when, as, whilea. when表时间，从句既可以用延续性动词，又可以用瞬间动词。Eg: When I get there I will call you.如果when引导的时状的主语与主句的主语相同，而从句的谓语又是be动词时，那么从句中的主语与be可省。Eg：When （you are）in trouble, you can ask her for help.如果wh

2、en引导的时状的主语与主句的主语相同时，往往可以用“when+分词”的形式代替该状从。Eg：When I came into the room(When coming into the room), I found the light was off.b. while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。主句的谓语动词通常是非延续性动词。Eg: He came in while I was reading a book. I met her while I was in school.c. as表时间，与when相似，但侧重强调主从句动作同在时间点或同时间段进行

3、。同时可表示主句的动作随着从句的动作的变化而变化。Eg: He jumps as he sings. As the wind rose, the noise increased.2. before(在之前)与after（在之后）Eg：See me before you leave.I saw them after I arrived.3. till与until肯定形式表示的意思是做某事直至某时。否定形式表达的意思是直至某时才做某事。Eg: Wait till/untill I call you.等着直到我叫你。She didnt arrive till/until 6 oclock. 她直到6

4、点才到但是置于句首时只可用untill.Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。否定形式有另外两种表达方式：(1)Not until 在句首，主句用倒装。Man did not know what heat was until the early years of the 19th century.=Not until the early years of the 19th century did man know what heat was. (2)It is not unt

5、il thatHe will not go to bed until his mother comes home.=It is not until his mother comes home that he will go to bed.4. as soon as/the moment/the instant/the second/the minute/immediately和hardly/scarcelywhen, no soonerthana. as soon as/the moment/the instant/the second/the minute/immediately 表示主句和

6、从句的动作同时发生。译为“一就”Eg：As soon as she heard the news, she began crying.b. hardly/scarcelywhen, no soonerthan都可以表示一就的意思，但主句谓语动词一般要用过去完成时，从句谓语动词要用一般过去时。Eg：I had hardly / scarcely got home when it began to rain. I had no sooner got home than it began to rain. 注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构：

7、 Hardly / Scarcely had I got home when it began to rain.

9、so) that/in order that（so）that/in order that表示“为了，以便”，引导的目的状语从句要用虚拟语气。Eg: He shouted at the top of his voice so that/in order that he might be heard.如果表示“为了，以便”的目的状语从句的主语与主句的主语相同，可用in order to或so as to替代。Eg：I came early so as to/in order to catch the first train.3. lest, for fear that, in caselest,

10、for fear that, in case表示“以免，以防”。其中 lest, for fear that要用(should)+动词原形的虚拟语气；in case后的从句可用虚拟语气，也可用陈述语气。Eg：I will not make a noise lest/ for fear that I (should) disturb you.Take your umbrella in case it rains.Ex. 1.

18、名词，要省略不定代词。若提前的是动词原形，与之连用的情态动词要置于原来的位置，即主语之后。though在引导让步状语从句时可像as一样倒装。2. while: 尽管Eg: While its none of my business, I will watch you.3. no matter (what, when, where): 无论（什么，何时，何地）Eg: The old man wouldnt believe anything no matter what you said.Please tell me the result no matter when you get it.4.
