We wont start until Bob comes. Dont get off until the bus stops.2. 条件状语从句(1)条件状语从句通常由if, unless引导。例如：What shall we do if it (下雨)tomorrow?Dont leave the building unless he (回来).(2)在条件状语从句里， 。例如：Ill help you with your English if I am free tomorrow.He wont be late unless he is ill.(3)“ ” 在意思上相当于 的复合句。例如：Hurry up, or youll be late.= Study hard and you will pass the exam.= 3. 原因状语从句(1)原因状语从句通常由because, since, as引导。例如：He didnt come to school because he was ill.As it is raining, we shall not go the zoo.Since you cant answer the question, Ill ask someone else.(2)because表示 。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since ，一般用来表示 。由as和since引导的原因状语从居多放在句首。例如：-Why arent going there?-Because I dont want to.As he has no car, he cant get there easily.Since we have no money, we cant buy it.(3) 。 Because you are late for school, so you have to stay here for another five minters. (判断对错)4. 结果状语从句(1)结果状语从句由sothat, suchthat, so that引导。例如：He is so poor that he cant buy a bike for his son.She is such a good teacher that everybody likes her.My pencil fell under the desk, so that I couldnt see it.(2)sothat语such.that可以互换。例如：在由so.that引导的结果状语从句中，so是 词，与 词连用。其结构是: “.so + （ ）+ that + 从句”。例如：He was so glad that he couldnt say a word.The hall is so big that it can hold 2,000 people.Mother lives so far away that we hardly ever see her.在由suchthat引导的结果状语从句中，such是 词，它修饰的可以是 ，也可以是 ；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加 。例如：It was such a hot day that nobody wanted to do anything.He had such long arms that he could almost touch the ceiling.He made such rapid progress that he did very well in the mid-term. 有时上述两种结构是可以互换的。例如：It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.It is such an important match that nobody wants to miss it.=The match is so important that nobody wants to miss it.(3)如果名词前由 等词修饰时，只能用so, 不用such。例如：Soon there were so many deer that they ate up all the wild roses.He has so little time that he cant go to the cinema with you.5. 比较状语从句比较状语从句通常由asas, 比较级 + than等连词引导。例如：Tom runs faster than John does.This classroom is as big as that one.6. 目的状语从句(1)目的状语从句通常由 so that, in order that引导。例如：We started early so that we could catch the first train.He studies hard so that he could work better in the future.We used the computer in order that we might save time.(2)so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：Speak clearly so that they may understand you. (目的状语从句)Jack is badly ill so that he has to rest. (结果状语从句)7. 让步状语从句(1)让步状语从句通常由although, though等连词引导。例如：Though he is young, he knows a lot.Although I am tired, I must go on working.(2)although(though)不能用在同一个句子中。例如：我们不能说：Though it was raining hard, but he still went out.应该说：Though it was raining hard, he still went out.或It was raining hard, but he still went out.8. 地点状语从句 地点状语从句常常由where来引导。例如： Go where you like. Where there is a will, there is a way.【实例解析】1.You will stay healthy _ you do more exercise, such as running and walking.

A. when B. if C. because D. though 答案：D。该题考查的是引导状语从句的从属连词的选择。从意思上看，只有选though才能说得通。 3.None of us knew what had happened _ they told us about it.

A. until B. as soon as C. since D. till 答案：B。该题考查的是引导状语从句的从属连词的选择。本题的意思是“一到那里，我就给你打电话。”要表达这个意思应选用as soon as。【中考演练】一. 单项填空1. _ hes old, he can still carry this heavy bag.A. Though B. Since C. For D.
