注：当先行词是way（方式方法）时，根据英 语的习惯常用that和in which 来引导定语从句， 而且也常常省略；另外当先行词是time（次）， 其前面用序数词修饰时，根据英语的习惯常 用that来代替for which 来引导定语从。如： 1) This is the first time (that)we shall see an English film. 2) The way (that) we did it very simple.
The boy (whom) you want to talk to is in the lab.
This is the boy. I sit behind him. This is the boy (whom) I sit behind.

关系代词前介词的确定
1.非限制性定语从句中，要表示先行词 的一部分时，可用“数词/代词 + of + 关系代词”的结构，如：
e.g. 1) There are 50 students in our class, twothirds of whom have been to Beijing. 2) He has three sons, all of whom are teacher
1.This is all____I know about the matter. A.that B.what C.who D.whether
2Is there anything else_____you want? A.which B.that C.who D.what
3.The last place _____we visited was the Great Wall. A.which B.that C.where D.it
以下情况，引导词用that，不用which。 1. 先行词为不定代词everything，little， much，all，anything，nothing。 e.g. Finally, the thief handed everything that he had stolen. 2. 先行词前有形容词最高级、序数词修饰时， 用that。 e.g. This is the best book (that) I’ve ever read.

4) He lives in the house whose windows open to south. 5) Please pass me the book whose cover is green.
