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?

　　Tom and John were brothers. They lived in the same room and were in the same class. One day they had a fight(打架), so they didn't speak to each other for a few days. One Monday evening, Tom was very tired(疲倦的) when he came back from school. He went to bed after supper. He did not say anything to John. John helped his mother with the housework. Then he did some homework. When he went to bed, he found a piece of paper on the small table near his bed. On it were the words, “John, wake me up(唤醒) at 7 a.m., Tom.”

　　When Tom woke up the next morning, it was nearly 8 a.m. and on the small table near his bed he saw another piece of paper. He took it and read these words, “Tom, wake up. It is 7 a.m., John.”
