名词性从句 在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 种类 作用 常用关联词 例句 主语从句 在复合句中做主语，相当于名词，一般置谓语之前，也可用it作形式主语，主语从句放主句之后 that, whether, if, as if, as though, who, whose, which, how, when, where, why, what, whatever, whoever, wherever Whether he will come or not doesn’t matter much. Whoever comes here will be welcome. 表语从句 在复合句中做表语，相当于名词，位于系动词之后 It looks as if it is going to snow. 宾语从句 在复合句中做宾语，相当于名词 He asked me which team could win the game. 同位语从句 放在名词之后(news, problem, idea, suggestion, advice, thought, hope, fact等) 表明其具体内容 You have no idea how worried we are. The fact that he lied again greatly surprised us. 主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whetherwho, what, which , whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever等。 That you don’t like him is none of my business.你不喜欢她不管我的事。 What he said is true. 他说的是真的。 Do you remember how he arrived almost at the end of the party? 你记得他几乎是在宴会快结束时才到的吗？ This partys really where its at, man! 啊，这个晚会真棒！ Tell us how you fulfilled the heavy task ahead of schedule.告诉我们,你们是怎样提前完成这一艰巨任务的。 We have reason to believe that the fighting on the border may develop into a full-blown war.
