名词性从句

名词性从句名词性从句可分为主语从句、表语从句、宾语从句和同位从句。 （一）引导名词性从句的连接词 1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。（二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesnt matter so much whether you will come or not. 3、that引导主语从句时，不能省略。 e.g. That he suddenly fell ill last week made us surprised.（三）表语从句 1、表语从句在复合句中作表语，位于系动词之后。 e.g. The question was who could go there. 2、引导表语从句的连接词that有时可省去。 e.g. My idea is (that) we can get more comrades to help in the work.（四）宾语从句宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。 e.g. I hope (that) everything is all right. He asked me why the meeting would be put off . （五）同位语从句 同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。 e.g. I have no idea when he will be back. The fact that he had not said anything surprised everybody. 用适当的连词填空并翻译句子： 1. I cant decide _ dictionary I should buy. 2. Thats _ he refused my invitation. 3.
