4.含有be动词的肯定句如何变否定句，一般疑问句及回答。
口诀：变否定，很容易，be后not加上去。变疑问，往前提，句首大写要牢记，句末问号别忘记。
肯定句：Wang Lingling is a student.王玲玲是一个学生。
把be动词提到句首，be动词要变大写。注意第一人称I 变you, we变you。回答时用yes 或no表示，结构：Yes, 主语+be动词，No，主语+be动词+not。
如：It is a book. 变为：Is it a book
陈述句：I am a boy. 变为一般疑问句：Are you a boy
5. 句中含有be动词的肯定陈述句变否定句。
先找肯定陈述句中的be动词，在be动词后加not.
如：It is a book. 变为: It is not a book.
