to的用法
1.Did you use to play the piano?
2.I didn't use to like tests.
这两个句子中为什么用use to而不是used to?在什么情况下用use to?use to有哪些用法?
used to do sth,是典型的动词过去式形式.因此它的否定形式和疑问形式,就如同任何其他过去式的动词一样要加助动词 did + use to...恢复原形.
如同.I went to Beiing.
I didn't go to Beijing.
Did you go to Beijing?
再问: did + use to和used to do是一样的吗?
再答: didn't use to do sth 是 used to do sth 的否定式; Did...use to do sth? 是 used to do sth 的疑问式。
