Question

I_______ like tests, but now I like them very much.

A．usedn’t to	B．didn’t used to
C．didn’t use to	D．used to not

Answer 1

C

试题分析：be used to sth习惯于某事;used to do sth过去常常做某事,本结构中use是行为动词,以疑问句及否定句要借助于助动词.联系下文,但是我现在非常喜欢.可知上文意思是,我过去不喜欢考试.可知选C.
点评：used to用法比较固定，需要注意use还可以作为被动语态使用，sth be used to do sth某物被用来做某事。
