初中英语复习语法知识点-句型转换

　　一、陈述句与疑问句、祈使句、感叹句间的转换

　　1、陈述句中肯定句变为否定句，大部分是用not来改变谓语结构，但也有借用否定意义的词，如nothing, nobody, none, neither, little, few, never, hardly等，例如：：

　　A：Tom does well in maths.

　　B：Tom doesn't do in maths.

　　A：He has much to do.

　　B：He has nothing to do.

　　A：All of my classmates like art.

　　B：None of my classmates likes art.

　　2、改为疑问句。根据上下句的结构和词的减少，来判断变为哪一种形式的疑问句。例如：

　　A：My brother often has breakfast at school.

　　B： Does your brother often have breakfast at school?

　　A：Tom's already weak in English.

　　B：Tom's already weak in English, isn't he ?

　　A：The red light changes every two minutes.

　　B：How often does the red light change?

　　3、改为感叹句。根据所给的句子结构和单词的词性，来确定使用哪一种感叹句的形式，例如：

　　A：This is an interesting book.

　　B：What an interesting book this is!

　　或 How interesting this book is!
