1、第十二讲：状语从句1、 【考点解读】状语从句是每年中考单选部分必考的题目之一。考查的重点是考生容易混淆比较相近的连词在逻辑行文和语篇结构中的使用。纵观近几年上海的小升初试题，从中可以看出命题者把着眼点放在了对条件状语、让步状语、时间状语从句的考查，时而涉及目的状语从句、结果状语从句和原因状语从句。所以我们这一讲会重点把小升初常考的几个状语从句讲解。2、 【知识讲解】知识点1状语从句 （1） 定义：用来修饰主句中的动词、副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句， 原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。（2） 状
2、语从句，+主句。 状语从句的位置： 主句+状语从句。 主句的主语，+状语从句，+主句的谓语以及其他成分。一、状语从句的分类1. 时间状语从句：在一个句子中作时间状语的句子。引导词：when(当时候); while(当时候); as(当时候); after(在以后); before(在以前);as soon as(一就); since(自从到现在); till / not until(直到才) 1）时间状语从句常遵循“主将从现”原则，用现在时态表示将来的动作或状态。例如：(1) I will ring you up as soon as I get to New York. As soon as
3、 I get to New York I will ring you up (2) I will tell him everything when he comes back. When he comes back,I will tell him everything(3) He wont believe it until he sees it with his own eyes. until he sees it with his own eyes,He wont believe it2) 主句+while+从句（主句和从句使用相同时态，有对比的含义，翻译为“而”）主句 （用过去进行时，谓语
4、动词是延续性动词） + when/as/while +从句(用一般过去时，谓语动词是瞬间动词）例如：(1) My mother was cooking while my father was watching TV. (2) The students were reading when the teacher came in.3) 在带有till或until引导的时间状语从句的复合句里，如果主句用肯定式，其含义是“一直到时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到才”, “在以前不”, 谓语动词可用瞬间动词。例如：(1) Lets wait till the rain st
5、ops. (wait是延续性动词，所以用肯定句) (2) We wont start until Bob comes. (start是非延续性动词，故要用not until，为否定句)2. 原因状语从句：在一个句子中表示原因的句子, 译作“因为”。连接词：由连词because（从句位置灵活）, since, as（从句一般置于句首）引导（1） I didnt go to school yesterday because I was ill.=（I was ill yesterday, so I didnt go to school.）（2） As /Since it is raining no
6、w,we had better stay at home.3. 条件状语从句连接词：if如果, unless (=if not) 除非。（主将从现原则）举例：If it doesnt rain tomorrow, we will go hiking.注意：1）条件状语从句，也遵循“主将从现”的原则。例如：(1) I will help you with your English if I am free tomorrow.(2) He wont be late unless he is ill.(3) We will have a picnic if it doesnt rain tomorr
7、ow. 2)“祈使句 + and (or)+ 陈述句”=带有条件状语从句的复合句。例如：(1) Hurry up, or youll be late. = If you dont hurry up, youll be late.(2) Study hard and you will pass the exam. = If you study hard, you will pass the exam.4. 结果状语从句结果状语从句由so that, so that引导。 例如： He has lost his bike so that he cant come to school on time
8、.（结果状语） 他丢失了自行车，所以不能准时到校。 Your shirt were so dirty that you must wash it.（结果状语） 你的衬衣这么脏，你应该把它洗洗。 注意： 由sothat引导的状语从句若表示否定，可以用tooto（太而不能）来替换。 例如： She was so angry that she could not say a word. =She was too angry to say a word. 她气得说不出话来。5. 让步状语从句 让步状语从句一般用though（虽然）、although（虽然）、even though（即使）引导。 例如：
9、 Though/Although he tried hard, he was not successful. 他虽然努力尝试，但没有成功。 He went on working though it was very late. 虽然很晚了，他还在继续工作。6. 方式状语从句as( 像.)，as if/as though(好像.)，the way（以.方式） 1）引导词 Lets study as Lei Feng studied. 让我们像雷锋那样学习吧。Think as I think. 像我这样去想。He talks as if/though he is drunk.从他谈话的样子来看他好
10、像醉了。 Please pronounce the word the way I do.请照我这样,读这个单词.三、【典例探究】【例题1】：( ) 1. Tom didnt eat dinner he finished his homework. He worked very hard. A. orB. whileC. ifD. until【答案】C【解析】选C。本题考查until引导的时间状语从句。句意为“直到Tom完成了作业，他才吃饭。”( )2.Well go for a picnic if it _ this Sunday. Wish you a lovely weekend.A. r
11、ain B. doesnt rain C. wont rain【答案】B【解析】选B。考查if引导的条件状语从句。当主句是一般将来时，if引导的条件状语从句应该用一般现在时。句意为“如果这个星期天不下雨的话，我们进行野餐”。故选B。( )3. Teresa is _ nervous _ she cant talk in front of the class.A. such, that B. too, to C. so, that【答案】C【解析】选C。考查状语从句引导词的用法。suchthat, sothat引导结果状语从句，such后接名词，so后接形容词或副词。tooto, too后接形容
12、词或副词, to后接动词原形。根据句意：特丽莎很紧张以至于不敢在同学面前说话。故选C.( )4. - Whats your plan for the summer holidays?-Ill go to Beijing_ the school term ends.A. in order that B. so that C. as soon as D. even though【答案】C【解析】选C。本题考查as soon as引导的时间状语从句，当主句中出现一般将来时，同学们要联想到从句也可能是一般将来时，再结合时间状语从句的时态，当主句和从句都表示将来时，主句用一般将来时，而从句要用一般现在时
13、表示将来。所以选择C。( )5. Well go for a picnic if it _ this Sunday. Wish you a lovely weekend.A. rain B. doesnt rain C. wont rain【答案】B【解析】选B。考查if引导的条件状语从句。当主句是一般将来时，if引导的条件状语从句应该用一般现在时。句意为“如果这个星期天不下雨的话，我们进行野餐”。故选B。四、【课堂运用】【基础】【练习1】I.
