(2) This is the pen which (/that) I’m looking for.(三) 关系代词who, whom和whose的用法1. 先行词指人，在从句中作主语时，用who；(1) She is the girl who/that lives next door.2. 当先行词为those时，用who；(2) Those who will join in my birthday party are my best friends.3. 在There be句型中主语作为先行词指人时，用who；(3) There is a great man who saved his country with his partners.4. 先行词指人，在从句中作宾语时，可以用whom和who；(4) That’s the girl whom/who/that I teach.5. 在定语从句中做定语时，用whose。

(1) This book is not such as I expect.（二）关系代词as和which引导的定语从句的区别as和which引导非限制性定语从句，有相同之处也有不同之处。

(1) He married her, as/which was natural.(2) He was honest, as/which we can see.2. as引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；as有“正如……，正像……”的意思which引导的非限制性定语从句只能放在主句之后。
