be动词变疑问句，直接提前。
否定句，直接在be动词后加not
eg:She is a student.
疑问句:Is she a student?
否定:She isn't a student.

一、含be动词的陈述句变一般疑问句
（一）变一般疑问句的规则
He is Tom. → Is he Tom?
①be动词提前
②首字母大写，原来的首字母改成小写
③句号改成问号
④改用升调
练习：
1. This is a book.
2. She is very beautiful.
3. It is his coat.
4. They are good friends.
注意①：I am…或We are…变成Are you…?
5. I am Jack.
6. We are Chinese.
注意②：my或our变成your
7. This is my mother.
8. These are our bags.
二、含be动词的肯定句变否定句
总的规则：be动词后加not
He is Tom. → He is not Tom.
