Attributive clause(定语从句)
定义:
定语：修饰名词或者代词，翻译为“……的”the beautiful girl the handsome boy
the lovely dog The girl in blue
定语从句: 在复合句中修饰名词或代词的句子在复合句中充当定语，所以叫作定语从句。
一般放在名词或代词后面The boy who is reading is Tom.

关系词分为关系代词
（that,which,who,whom,whose）和关系副词(when,where,why)。

非限制性定语从句
1.非限定性定语从句与主语的关系不是十分的密切，只是对先行词作些附加说明，如果去掉，主句意思仍然清楚。
主句与从句往往用逗号隔开。
His dog, which was now very old, became ill and died.
The train which has just left is for Xi’an.
2.在非限制性定语从句中，不能用that 和why来引导定语从句，只能用who/whom指人，用which指物，且引导定语从句的关系代词或关系副词不能省略。
I advised him to give up smoking, which he did n’t accept.
The hospital nearby, where my father used to work as a doctor, has been rebuilt recently.
3.能够引导非限制性定语从句的关系代词常常是who, whom, whose, which. 关系副词where/when也能引导非限制性定语从句。
The chairman，who spoke first, sat on my right.
His speech, which bored everyone, went on and on.
I’m seeing the manager tomorrow, when he will be back from New York.
