疑问代词what和which的用法区别

What...? 与 Which...?

1. what 与 which 都是疑问代词，都可以指人或事物，但是what仅用来询问职业。如：

What is your father? 你父亲是干什么的?

该句相当于：

What is your father's job?

Which 指代的是特定范围内的某一个人。如：

---Which is Peter? 哪个是皮特?

---The boy behind Mary. 玛丽背后的那个男孩。

2. What...?是泛指，所指的事物没有范围的限制;而 Which...?是特指，所指的事物有范围的限制。如：

What color do you like best? (所有颜色)

你最喜爱什么颜色?

Which color do you like best, blue, green or yellow? (有特定的范围)

你最喜爱哪一种颜色?

3. what 与 which 后都可以接单、复数名词和不可数名词。如：
