(从句中什么都不缺) I don’t know which book I should choose. (从句中缺定语) 定义:充当主语功能的句子叫主语从句 That she was chosen made a great stir (轰动) in her school. 注意: ①it作形式主语的that-从句有以下四种不同的搭配关系: It + be +形容词+ that-从句 It is necessary / important that…. …是有必要 / 重要的….

(去掉该结构后,句子成分完整) 词 主语从句:It was a pity that you shouldn’t go to see the film. (在句子中作主语成分) ③whatever /whichever/ whoever引导主语从句的区别 Ⅰ Whatever 是what的强调形式表示“无论什么”相当于 anything that… 从 Whatever / Anything that she does is wrong. Ⅱ whoever 是who的强调形式,表示‘无论谁’ 相当于anyone who…. 句 ~ever Whoever / Anyone who walks around in such a heavy rain will catch a cold. Ⅲ whichever ‘无论哪个;无论哪些’,既指人,又指物. 可修饰名词与of连用 Whichever book you borrow doesn’t matter to us. Whichever of us fulfills his task will lend a hand to others. 定义:在复合句中充当宾语功能的句子叫宾语从句 We can learn what we didn’t know.

I took it for granted that they were not coming. ④ that一般不接介词宾语,偶尔可作except, in的宾语;其它介词后面需用it作形式宾语 He differs from his roommates in that he devoted his spare time to reading. He knows nothing about Jim except that he is from London. You can depend on it that he will help you in time of emergency. ⑤表示好恶的动词如like; hate; love;enjoy; dislike; appreciate等后面不能直接跟宾语; I like it when the weather is sunny.
