(主语) What he does is important. (主语) This is his job. (表语) This is what he does every day. (表语) I don’t like his job. (宾语) I don’t like what he does every day. (宾语) I don’t know about the fact that he is a teacher. (同位语) I don’t know about the man, Mr. White. (同位语) 得出结论：因此根据它在句中不同的语法功能，名词从句又可分为四类，即：主语从句、宾语从句、表语从句和同位语从句。 三．引导名词性从句的连接词： 1、连接代词：who, whoever, whose, whom, whomever, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 I don’t believe __________ he has achieved so far. __________ breaks the law should be punished. 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 __________ we will hand in the project will be discussed later. Parents are thought to understand __________ important education is to their children’s future. The reason __________ he was absent was that he was ill. 3、连接词：that, whether, if, as if, as though。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。 I don’t care about __________ you have money or not. The problem is __________ Tom is able to arrive on time. __________ the meeting will be held here is not decided yet. It looks __________ it is going to rain.
