谁能告诉我，从句中的that、which、where和who有什么区别吗，分别在什么情景下使用？、、
例如这题：What do you usually do in your leisure time?
I enjoy reading in the library_______I lose myself in a world of good books.
A.which B.that C.where
还有一个题，也是不明白
Have you brought _______with you ?We won't have time to come back.
Don't worry .All the things we need are here ,in this big bag.
A.something B.nothing C.anything
这道题为什么不是C呢，疑问句中不是用anything 吗？
还有英语中的不搭配，就是衣服类的不搭配该怎么说？
