名词性从句讲.doc

名 词 性 从 句 一、 概述 在复合句中起名词作用的从句叫名词从句(Noun Clauses）。名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 名词性从句在功能上相当于名词 主语 His job is important. What he does is important 表语 This is his job. This is what he does every day. 宾语 I don’t like his job. I don’t like what he does every day. Yao Ming will talk to us about his travel. Yao Ming will talk to us about what he saw in the USA. 同位语I don’t know about the man, Mr. White. I don’t know about the fact that he is a teacher. 马上练练：画出下列句子中含有的从句，并指出是哪类从句 1.
