英语中的定语从句详解、

内容很多,不能全部列举,为什么不自己看语法书?
说点重点的：
1。 Last month,I went on a tour to Hangzhou, which is close to Shanghai。
Not:。。。Hangzhou, that- 逗号后的非限制性定语从句不可用 that- 引导。
2。 China has built its first aircraft carrier, which indicates China is building its Navy。
Not: 。。。aricraft carrier, that- 非限制性从句并指代前句描述的整个情形,不用that-
3。 Last Sunday I bought a new English-Chinese dictionary for which I paid 100 yuan。
Not:。。。dictionary for that- 不可：介词 + that-
(But: Last。。。dictionary (which/ that) I paid 100 yuan for。)
介词不提前,留在句末,可以,替代或指代“宾语”时,也可省略
4。 much/ all/ anything/ nothing/ everything/ a little + that- (Not: 。。。+ which- )
不定代词(something 除外） + 不可用 which-
5。 。。。the best/ the second +　n　＋　that－　　（NOt：．．．which－）
最高级/ 序数词 + 先行词 + 只用 that-
6．。 sb and sth + that- (Not: sb and sth + which-)
人 + 物 （同时做先行词）+ 只用 that-
who- vs。 whom
1。 I don't know the girl who's speaking with Mr。 Smith at the gate of the school。
。who- 在从句中作‘主语“时,不可用宾格whom-,也不可省略。
2。 Look at the pretty girl (whom/who) I don't know。
指代 ”宾语“时,正式的用whom-,口语中可用who-, 都可省略。
3。 We went to the aged home to see the old people of whom the volunteers were taking care。
Not:。。。the old people of who- 介词 + 不可跟 主格的 who-
