限制性定语从句与非限制性定语从句
1、限制性定语从句：从句与主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。对先行词起修饰限制的作用 e.g. I was the only person in our office that was invited to join the party .（去掉定语从句，意思就不完整）
2、非限制性定语从句：从句对先行词关系不密切，去掉定从句，意思仍然完整。形式上用逗号隔开，不能that用引导。 对先行词起补充说明的作用，与主句往往用逗号隔开。 e.g. Tom’s father, who is over sixty, still works hard day and night.（who引导非限制性定语从句，整个句子可分成两句来翻译）
在非限定性定语从句中，
先行词指人的时候，关系代词只能是who,whom，不能用that； There are many students in the classroom, most of whom are boys. 先行词指物的时候，关系代词只能用which, 不能用that。 I have a lot of books, most of which are English books.
②代表整个主句的意思；
He was late again, which made the teacher very unhappy.他又迟到了这使得老师很不高兴 ③介词 + 关系代词。
This is the room in which/where my father lived last year. 这是父亲去年居住过的房子。 This is the room which/that my father lived in last year.
