非限制性定语从句是与主句之间用逗号分开的定语从句。
它只是对先行词作些附加的说明, 如果去掉, 主句的意思仍然清楚。
请把我桌子上的书递给我。
Translate:
Please pass me the book which/that is on my desk.
Please pass me my Chinese book, which is on my desk.
请把我的语文书递给我，它在我桌子上。
非限制性定语从句是对先行词的附加说明，去掉之后，意思明确，与主句通常用 “，”隔开，把非限制性定语从句放在句子中，其前后都需要用逗号隔开。
限制性定语从句是先行词不可缺少的部分，去掉之后，主句意思不明确。
先行词不唯一，缩小范围，限定。
先行词唯一，没必要限定，为附加说明。

whose =... of which/of whom
关副: when, where, why
=介词+which
2). 引导词不同
