怎样回答 Used you to go fishing否定回答是后面是否要加to ,肯定呢?
1. Used you to go shopping?
否定回答:No, I used not to.
肯定回答:Yes, I used to.
2. 解释:used to do sth中的do sth如果是行为动词原形,则回答时到to为止,其实这也是不定式省略的原则.
3. 再如:
--Would you like to go to my birthday party?
--Yes, I'd like to.

You mean: Do you used to go fishing?
Negative response: No I don't used to go fishing.
Positive response: Yes I do go fishing.

肯定回答加to
否定回答不加
