什么叫名词性从句？ 在句子中起名词作用的句子叫名词从句 (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 名词性从句在功能上相当于名词 Subject Clauses 主语从句 考点二 注意：从句作主语 ，谓语动词一般用单数 What引导的主语从句，可根据表语决定 What he needs---- that book. What he needs __ some books. Object Clauses 宾语从句 他建议他们明年去香港旅行。 He suggested that they should make a trip to Hong Kong next year. 我们的成功取决于我们互相之间合作得如何。 Our success depends on how well we can cooperate with one another. 没人敢确定一百万年以后地球是否存在 No one can be sure whether the earth will exist in a million years. 你可以做你喜欢做的任何事情 You may do whatever you like to do 引导宾语从句的that在下列情况下一般不省略： 1. 宾语从句前有插入语。 We hope, on the contrary, that he will stay at home with us. 2. 在介词后。 He has no special fault except that he smokes too much. 3. that在与之并列的另一个宾语从句之后。 He said (that) the book was very interesting and that(不省略) all the children like to read it. 4. 有间接宾语时。 He told me that he was leaving for Japan. 5. that从句单独回答问题时。 —What did he hear? 他听说了什么事？ —That Kate had passed the exam. 6. 在“it(形式宾语)+补语”之后时。 I think it necessary that he should stay here. 7. 位于句首时。如： That our team will win, I believe. 3. 否定的转移:若主语谓语动词为think, consider, suppose, believe, expect,, imagine等,其后的宾语从句若含有否定意义,一般要把否定词转移到主句谓语上,从句谓语用肯定式。 (我认为这件衣服不适合你穿。) I don’t think this dress fits you well. 4. It 作为形式宾语而真正的宾语从句则放在句尾, Like/love/hate/appreciate/help/look/depend on/see to/ count on/rely on + it + when/if/that clause I hate it when people speak with their mouths full. Sb.+ think/find/make + it +adj./n.+that clause He made it clear that he would leave office soon. Predicative Clauses 表语从句 是在复合句中作表语的名词性从句, 放在系动词之后,一般结构是“主语+系动词+表语从句”。可以接表语从句的系动词有be, look, remain, seem等。另外,常用的还有the reason why … is that … 和It is because …等结构。 他缺席的原因是因为他生病住院.
