小博士：我们在这几个月的学习里，接触到不少的疑问词，其中疑问代词占大多数。那么疑问代词有哪些？又有哪些用法呢？看看下面的总结吧！

　　1)疑问代词在句中起名词词组的作用，用来构成疑问句。疑问代词有下列几个：

　　指人：who，whom，whose

　　指物：what

　　既可指人又可指物：which

　　2)疑问代词在句中应位于谓语动词之前，没有数的变化，除who之外也没有格的变化。无论是做疑问代词还是限定词，which和what所指的范围都是不同的。what所指的范围是无限的，而which则指在一定的范围内，例如：

　　Which movies do you like best?

　　你喜欢哪几个部电影？

　　What movies do you like best?

　　你喜欢什么样的电影？

你明白了吗？那么就请选用刚才我讨论过的疑问词完成下面句型转换。

1　　My favorite subject is science.

________ ________ your favorite subject?

2　　He likes art best.

________ ________ he like best?

3　　My science teacher is Mr Green.

________ ________ your science teacher?

4　　He's really busy today.

________ ________ really busy today?

5　　Betty's backpack is in her bedroom.

________ backpack is here?
