a question about 'which' and 'that'1.He talked happily about the men and books ________ interested him greatly in the school. A. which B. that2.That was the most interesting film ____ I _________. A. that; had ever seen B. which; had ever seen3.I'm not interested in any books __________ here. A. that you brought B. which you brought请问这三题分别应该选什么?为什么呢?that 和 which 的用法有什么不同吗?在从句中担任不同语法成分时有什么不同?与主句中的成分有关吗?谢谢!

1 B 有人有物用that
2 A *，有most等通常用that
3 A any,all, 等用that

1.B which只能修饰人，而that用的范围最广，可修饰人或物，因为这里的宾语是the men and books.（人和物）
2.A 这里是定语从句，且修饰物(film)，用that；而which 虽然修饰物，但要有选择范围，e.gWhich coat do you like best?
3.A 同上
看懂了吗？

Answers
B,先行词中既包含有人又包含有物,关系代词用that
A,先行词被*修饰,关系代词用that
A,先行词被any修饰,关系代词用that
用that不用which的情况
1.当先行词为all,much,little,none及由any,every,some,no所构成的复合不定代词时.
2.当先行词被any,few,little,no,all,much,some等词修饰时.
3.当先行词为序数词或被序数词所修饰时.
4.当先行词为形容词*或被形容词*修饰时.
5.当先行词被the very,the only,the last,the just,the same等修饰时.
6.当先行词既包含人又包含物时.
7.当先行词是疑问代词who,which,what或主句以这些词开头时.
8.当先行词为主句表语或关系代词为从句表语时.
9.先行词为time时,当time表示次数,引导词用that,可省略.当表示时间,可用that或when引导,都可省略
用which不用that的情况
1.在“介词＋关系代词”结构中,关系代词必须用which.
2.先行词为“those＋表事物的复数名词”时,关系代词通常只用which而不用that.
最后,记得这个特殊情况吧：当先行词是表示原因或方式的名词时,可以用that引导定语从句,相当于介词+which,that可以省略.
