简单句各句式转换的方法
一、肯定句改否定句的方法:一步法
1、如果肯定句中已有be,则在be动词后加not。如:is not , are not , am not, was not, were not;
2、肯定句中如已有can,should, will等,则在其后加not。如:cannot, should not, will not; 3、肯定句中如没有上述Be动词或情态动词则先借
助动词do/does/did的否定don’t/doesn’t/didn’t。
4、肯定句中如有some则改成any。
eg:把下面的句子变成否定句。
1.She is watching TV now.
2.We go to school onSunday.
3.His father works hard.
4.Jack's mother is a nurse.
5.The cat runs fast.
6.They like reading books.
7.My grandpa gives me a hot dog.
8.Tom often walks to school.
9.I have a doll.
10.It is eating fish. 二、 肯定句改一般疑问句的方法——三步法 1、肯定句中有be动词时,把be动词提到句首,剩下的照抄,(some 改成any,my改成your等)句号改成问号。
