问题补充：
英语中的定语从句详解、主要是引导词的详解例如which与that的区别、还有who与whom之类的,越详细越好对了还要带着例句.谢、
答案：
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 know the girl whos 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 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-
Also, we say: We...the old people (whom/ who) the volunteers were taking care of.
但介词不提前,留在后面,二者皆可,也都可省略,区别同上2.
