I piayed football yesterday afternoon.变一般疑问句,并作否定回答
一般疑问句形式: Did you play football yesterday afternoon?
否定回答:No, I didn't.
英语中,由陈述句变一般疑问句通常是将谓语动词提到主语前,并将句号变为问号即可,但根据谓语动词不同又分为3类.
1. 谓语动词为be动词(am, is, are, was, were), 直接将be 动词提到主语前面,并将其首字母大写,然后将句尾的句号改为问号即可.
例句:The boy is three years old.
(一般疑问句) Is the boy three years old?
(肯定回答) Yes, he is.
(否定回答) No, he isn't.
2. 谓语部分含有情态动词(can, could, may, might, will, shall, would, should等), 只需将情态动词提到主语前,其他动词不变,然后将句尾的句号改为问号即可.
例句:The boy can play football.
(一般疑问句) Can the boy play football?
(肯定回答) Yes, he can.
(否定回答) No, he can't.
3. 谓语部分是实意动词(speak, play, watch等), 需要借助于助动词do, does,did, 将助动词提到主语前,其他动词不变,然后将句尾的句号改为问号即可.
例句:The boy played football with his friends yesterday.
(一般疑问句) Did the boy play football with his friends yesterday?
(肯定回答) Yes, he did.
(否定回答) No, he didn't.
