which
u限制性定语从句说明先行词的情况，对先行词起限定作用，与先行词关系十分密切，不可用逗号隔开，也不可省略，否则全句意义不完整。限制性定语从句的先行词往往是某一个词。如， Do you know the professor who is speaking at the meeting
u非限制性定语从句只是对先行词补充说明，没有限定作用，它与先行词的关系比较松散，因而不是关键性的，如果省略，原句的意义仍然完整。非限制性定语从句常用逗号与主句隔开。非限制性定语从句的先行词可以是一个词，也可以是句子的一部分，甚至是整个主句。如， English is an important subject, which every students should study well. He has passed the examination, which makes his parents happy.
All can be done must be done.
The radio, he bought yesterday, doesn’t work now.
The first thing we should do is to get some food.
