名词性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。

whichever (book) you like.
whose
• Whose表示“谁的”。 • 在句子中充当定语的成分，其后一定会加
when, where, how, why, however… when, where, how, why, however…
that的用法
• 在从句中不充当任何成分，也没有任何具体意思。 • 引导的句子相当于一个陈述句。 • 只起到连接的作用。

(that在从句中不充当任何成份)
The idea （that/which） he gave surprises many people．
(that在从句中作gave 的宾语)
宾语从句须注意
1) 由疑问词引导的从句中, 词序按陈述句 顺序排列。
e.g. I wonder what he is doing. 注意：I wonder what was wrong /the matter
with him. 2)当主句的谓语动词是过去时的时候, 从句的 谓语动词应用相应的过去时。自然规律和客观 真理例外。
4) That在其他名词性从句中均不可省略，只有 在宾语从句中that有时可以省略，但在并列 的宾语从句中第二个that 不可省略。
e.g. He said (that) he would leave and that he would never come back again.
5) 否定的转移 若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, 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。 e.g. I /we don’t think this dress fits you Well, does it?
3. 连接代词: what, whatever, who, whoever, whom,whose, which（哪个）： 不仅起到连接一个句子的作用,同时也是从句 的一个组成部分；从句不完整，缺成份。
