1、精选优质文档-倾情为你奉上 初二英语复习课教案复合句状语从句一、复习目标： （1）掌握状语从句的作用。2）掌握状语从句的意义。（3）掌握各种不同类型的状语从句。二、知识要点：状语从句在句中作状语，修饰句中的动词、形容词或副词等。状语从句由从属连词作关联词，从属连词在从句中不充当句子成分。状语从句在主句之前，一般要用逗号分开，朗读时用升调。状语从句在主句之后，一般不用逗号，朗读时用降调。 状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点等类型。 1. 时间状语从句 (1) 常用的连词有when（当时候），while（当时候）,before(在以前)，after（在

2、以后），until(till)（直到为止）,since（自从以来）, as soon as（一就）等。 (2) 时间状语从句中一般不用将来时，若谈论将来的事情，往往用一般现在时代替： 如：Ill go on with the work when I _ (come) back tomorrow. As soon as he _(finish) the work, he will come to see me. 2. 条件状语从句 常由if (假如、如果) No matter (不管) 来引导，如果主句是一般将来时，从句往往用一般现在时来表示将来。 如： Ill go for a picnic

3、if it _(be) fine. No matter what he _(say)，I wont believe him， 3. 原因状语从句 (1) 常由because, since, as引导。 (2) because表示直接的原因，着重点在从句，用于回答why, 语气最强。 because 不能与 so 连用。 since一般表示对方已知的，无须加以说明的既成事实的理由，全句中心在主句，语气比because弱，常译为“既然”。 as表示十分明显的原因，一般说明因果关系，着重点在主句，语气较弱。常译为“由于”。 for是个并列连词，只能放在另一个并列分句后面，表示一种推理或解释，或用作附

4、加说明，而不是指理由或原因，语气最弱，一般不放在句首，常译成“因为”。 如：_ it is raining hard, we wont go hiking. _ you are ill, Ill go alone. I cant go to school _ I am ill. You havent met him, _ he didnt come here. 4. 结果状语从句 一般由so.that, such.that引导，so 与such的区别： (1) so形容词a / an名词 (2) sucha / an形容词名词 （3）such形容词不可数名词 / 可数名词复数 (4) soma

5、ny / much / few / little形容词名词 如：Its _ a heavy box that nobody can move it. Its _ heavy a box that nobody can move it. There are _many books in the library 5. 目的状语从句 往往由so that,引导，如：Ill speak slowly_ you can understand me. 6. 比较状语从句 常由as.as, than, not as / so.as等引导。比较从句部分常是省略句， 如：Im taller _ he (is).

6、 Science is not _ popular _ English. 7. 让步状语从句 由though或although (虽然) 等引导，但不能与but同时连用， 改错：Though it snowed heavily,but they kept on working. 8 方式状语从句 常用as if ,as though（好像）引导。如：He acted as if (though) nothing had happened. 9、 地点状语从句 常用where, wherever引导。 如：Ill go where work is hard.典型例题解析 例1 The quest

7、ion was _ difficult that nobody could answer_. A. very.them B. very.it C. so.them D. so.it 解析 因为句中有that,所以前面用so,构成sothat从句，而question是单数，用代词it，故选D。 例2 It was _that he had to ask for help. A. such big work B. so big a work C. so a big work D. such big job 解析 work是不可数名词，指工作或工程，故选A。 例3 He wont believe i

8、t _ he sees it with his own eyes. A. when B. after C. until D. as soon as 解析 此句是notuntil,“直到才”。故答案选C。 例4 Ill go _ with you _ next Sunday. A. hunting.when I will have time B. to hunt.until Im free C. boating.if I have nothing to do D. to boat.as I will not be so busy 解析 去打猎、划船常用go hunting, go boating

9、，所以应在A和C中选择，又因为when和if在句中引导状语从句时，要用一般现在时表示将来，故选C。 例5 Its almost three years _ I last saw her. A. since B. when C. that D. after 解析 本句表示自从上次见到她几乎有三年了，句型Its+时间段+since从句(过去时)，故选A。 三、选讲例题 用所给动词适当形式填空 例6 Ill go to Shanghai if I _ (have) time tomorrow. And I want to know if you _ (have) time to go with me

10、. 解析 第一句中if是“假如”的意思引导状语从句，要用一般现在时表示将来时，第二句中if是“是否”的意思，引导宾语从句，仍用将来时。 例7 Could you tell me when he _ (return) home next week? Sorry, I cant. But I will ring you up when he _ (return) home. 解析 第一句中的when意思是“什么时候”，引导宾语从句用将来时态，第二句中的when是“当时”的意思，引导时间状语从句，用一般现在时表示将来。 四、课内追踪练习单项选择 ( ) 1.Jack was tired _he pl
