1、含有be动词的句子

He is a teacher.

The girl is very beautiful.

Tim and Jack are students.

★变疑问句将be动词移到句首

Is he a teacher?

Is the girl very beautiful?

Are Tim and Jack students?

★变否定句在be动词后面加not

He is not a teacher.

The girl is not very beautiful.

★肯定回答及否定回答

Yes, he is. / No, he is not.

Yes, she is. / No, she is not.

2、不含有be动词的句子，即含有一般动词的句子。

(1)第三人称单数及单数名词

★变疑问句在句首加does, 动词变为原型

Does he like books?
