Answer 1

只宜于用that的情况：

1.先行词是形容词最高级或者它的前面有形容词最高级时

eg:English is the most difficult subject that you will learn during these years.

2.先行词是序数词,或它的前面有一个序数词时

eg:He is the last person that I want to see.

3.主句中已有疑问词时

eg:Which is the bike that you lost?

4.先行词既有人又有物时

eg:The bike and its rider that had run over (撞倒了)an old man were taken to the police station.

5.先行词是all,much,little,something,everything,anything,nothing,none,the one等代词时

eg:You should hand in all that you have.

6.先行词前面有only,any,few,little,no,all,one of,the same,the very等词修饰时

eg:The only thing that we can do is to give you some money.

7.有两个定语从句,其中一个关系代词已用which,另外一个宜用that

eg:Edison built up a factory(办了一个工厂) which produced things that had never been seen before.

在定语从句中
that既可以指人也可以指物
which只能指物或者事
一般情况下是可以通用

但是

A.有两种情况只能用which

1.关系代词前有介词时

eg:This is the hotel in which you will stay.

2.如有两个定语从句,其中一句的关系代词是that,另一句宜于用which.

eg:Let me show you the novel that I borrowed from the liberary which was newly open (新开放) to us.

Answer 2
