肯定句改为否定句时,一律在be动词、助动词和情态动词后加“not”,改为一般疑问句时,一律将be动词、助动词和情态动前移到句首(首字母大写)。肯定回答用“Yes”;否定回答用“No”。“Yes”或“No”后面的主语必须用代词,“No”后面必须用否定缩略式。如:
将下列句子改为否定句、一般疑问句,并做肯定、否定回答:
1. There are some computers in this school. (be动词)
There aren’t any computers in this school.
Are there any computers in this school? (Yes, there are. / No, there aren't.)
2. Li Ming’s father can drive the car. (情态动词)
Li Ming’s father can’t drive the car.
Can Li Ming’s father drive the car? (Yes, he can. / No, he can’t.)
3. She has already finished his homework now. (助动词)
She hasn’t finished his homework yet.
Has she finished his homework yet? (Yes, she has. / No, she hasn’t.)
