Question

which/that 在定语从句中的使用问题

This is the biggest playground that we have ever built. 这样对么?那么 This is the biggest playground which we have ever built呢?

Answer 1

不可以用which
共有七种情况下只能用that 不能用which
A. 先行词是最高级形容词或者它的前面有最高级形容词时
eg. This is the best that has been used against pollution.
English is the most difficult subject that you will learn during these years.

B. 先行词是序数词，或者它前面有一个序数词时
eg. He is the last person that I want to see.
It is the first American movie of this kind that I've ever seen.

C. 主句已有疑问词who或which时
eg. Which is the bike that you lost?
Who is the woman that was praised at meeting?

D. 先行词既有人又有物，宜用that
eg. Do you know the things and persons that they are talking about?

E. 先行词是all,much,little,something,everything,anything,nothing,none,the one等代词时
eg. You should hand all that you have.

F. 先行词前面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.

G. 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. He built up a factory which produced things that had never been seen before.

Answer 2

This is the biggest playground that we have ever built对的
This is the biggest playground which we have ever built不对
对于最高级修饰的名词要用定语从句只能用that引导

Answer 3

在这里不能用which。先行词playground前有最高级the biggest。当先行词是最高级或被最高级修饰时只能用that不能用which

Answer 4

第一个是对的，因为定语从句指物先行词被最高级修饰，关系代词用that不用which

Answer 5

第一个正确。
有最高级的情况下只能用that
