Unit 2宾语从句(一)讲义--牛津译林版九年级上册英语.docx

牛津译林版九年级上册英语Unit 2宾语从句（一）解题根本办法：认识宾语，认识从句，注意语序、时态以及各个连词的区别思考：1. 什么是宾语？ 2. 什么是宾语从句？3. 哪个连接词没有含义？哪些连接词是给句子补充含义的？一. 宾语从句的连接词的用法在句子中起宾语作用的从句叫宾语从句。常用的连接词有：that; if; whether; what; which; who; whom; when; where; how; why等。注意：Unit1讲了并列句的连词，本单元的连词为复合句的连词，都是连词，起连接作用。 注意区分并列句和复合句。1. 宾语从句是陈述句时，因为在口语中that在从句中不做任何成分，也没有任何具体意思，因此在口语和非正式文体中常被省略。例：Lucy says (that) she wont take part in the sports meeting.2. 宾语从句是一般疑问句时，用if或whether来引导。 if, whether意为“是否”，whether还可以与or not连用。注意：怎么理解“宾语从句是一般疑问句时”这句话？例：Lets see if/ whether we can find out some information about this film.相当于Can we find out some information about this film?也就是，当从句表达不确定的含义的时用if或whether。if和whether用法的区别：(1) 动词不定式之前只能用whether I cant decide whether to go with him.(2) Whether.(or) not是固定搭配(3) 介词后只能用whether We are interested in whether he can finsih the work without any help.结合“当宾语从句为一般疑问句时”理解二. 宾语从句的语序1. 宾语从句的语序为陈述句语序，即便从句本身为疑问句，也要变为陈述句。注意：1. 宾语从句本质上就是陈述句。主句为疑问或陈述形式都不影响从句的语序。2. 不管主句部分怎么变化，从句一定用陈述句。例：Could you tell me when it will be on show?I wonder when it will be on show.三. 宾语从句的时态1. 如果主句是一般现在时、现在进行时、现在完成时、一般将来时或祈使句时，宾语从句的时态根据具体情况而定。例： I know she lived here five years ago. Weve heard that she has been back for a long time.2.如果主句是过去的某种时态（一般过去时，过去进行时，过去完成时），宾语从句时态应用相应的过去的时态。例：I didnt know she talked with hert mother about this thing.3. 客观事实、格言、科学真理，从句时态用一般现在时。例：He said that the earth goes around the sun.四. 专项练习I. 选择题1. -Do you know _ Amy will go to the charity show or not? -Yes.
