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
