1、状语从句状语从句指的是在主从句中作的从句，修饰主句中的动词、形容词或副词等。状语从句放在主句之前时，常用逗号分开；假设放在主句之后，一般不用逗号。按其意义和作用划分，初中阶段常见的有以下几种: 时间状语从句一般来说，时间状语从句常由连词when, before, after, as soon as或until引导。在使用时,从句一般不用一 般将来时态。假设主句为一般将来时态或是含有将来的意味时，时间状语从句常用一般现在时态来代替将来，即 “主将从现”。如：I will go to the cinema as soon as I finish my homework.我一完成作业就去 电影院。W

2、hen I grow up, I will join the army.当我毕业了，我就要去参军。 条件状语从句条件状语从句常由if （如果）、unless （除非）或aslongas （只要）来引导，同样适用于“主将从现”。 如：We will stay at home if it rains tomorrow.如果明天下雨了，我们就会呆在家。He won t come here unless he is invited.除非被邀请，否那么他不会到这儿来的。As long as you give me money, I will go with you.只要你给我钱,我就跟你走。 原因状语从

3、句原因状语从句常由because （因为），since （既然；由于）或as （由于）来引导。在使用时，注意because 和so （所以）不能用在同一个句子中。如：Since you can? t help me, T 11 find someone else.既然你帮不了我,那我就找其他人吧。He failed the exam because he didn t work hard.=He didn? t work hard, so he failed the exam.因为他不努力，所以考试没有及格。 让步状语从句让步状语从句由although或though （虽然;尽管）来引导。注意

4、，在使用时，though或although不能和 but不能用在同一个句子中，两者只能用其一。如：We still worked in the field although / though it was raining hard.=It was raining hard, but we still worked in the field.尽管天下着大雨，但是我们仍然在地里干活。 目的状语从句目的状语从句主要由 气0由讥”（以便，为了）或“皿。出已由沆”（为了）来引导，谓语中常含有11，18H, can, could, will, would 等情态动词。如：He gets up early

5、every morning so that he can catch the bus.他每天早上起得都很早，以便能赶上公交车。【温馨提示】当从句主语与主句主语一致时，可用so as to, in order to。如:He worked day and night in order that he could succeed.=He worked day and night in order to succeed. 他夜以继日地工作为的是取得成功。 结果状语从句结果状语从句主要由“so that（结果是），“sothat/suchthat （如此以至于）来引导。如:It s so hot th

7、 harder.你不努力就会失败的。Dont come unless 1 call you.我不叫你就另U来。注意：unless从句里的谓语只能是肯定式,因为本身unless表示否认。误 : Unless you do not work, you will fail.正 ： Unless you work hard, you will fail.正 ：If you dont work hard, you will fail.3) as long as引导条件状语从句,表示“只要”。As long as you study hard, you wont fail in the exam.【温馨提

8、示】X主将从现原那么：主句为一般将来时，从句用一般现在时；如：ril visit the Great Wall if it doesnt rain tomorrow.如果明天不下雨，我将去游览长城。X如果if引导的条件状语从句所表示的前提或条件正在进行，从句要用进行时，主句通常用将来时；如: We will give you a good price if you are thinking of buying it.如果你考虑买它，我们会给你一个好价钱。X“祈使句+and/or引导的结果状语从句”中，祈使句在意义上相当于一个条件状语从句；如：Use your head, and youll f
