    2．行为动词的否定式和疑问式: (1)若肯定句中只有一个行为动词,那就得在行为动词前加上did not或缩略式didn’t,并把这个行为动词由过去式改为动词原形.例如: a. I called Lin Tao yesterday afternoon. →I did not / didn’t call Lin Tao yesterday afternoon. b. I borrowed a book from Sun Yang last Sunday. → I didn’t borrow a book from Sun Yang last Sunday. (2) 行为动词的一般疑问句 若在陈述句中只有行为动词的过去式,那就得在句首加上一个助动词did来帮助提问,然后把句中的行为动词由过去式改为动词原形,并在句末打上问号.回答时别忘了还用did.例如: a. We stayed there for 10 days last month. → Did you stay there for 10 days last month? Yes, we did. / No, we didn’t. b. Mary had a delicious dinner yesterday evening. → Did Mary have a delicious dinner yesterday evening? Yes, she did. / No, she didn’t 练习: 【查看更多】
