Question

You _______ any noise in the room. We are reading now.

A. had better not to make           B. had not better to make

C. had better not make              D. had not better make

Answer

C

【解析】

试题分析：句意为：你最好不要在房间里吵闹，我们在看书。根据语境可知，这里表示建议或劝告某人不要做某事。结合选项，had better do sth表示最好做某事，其否定意义为：had better not do sth，即最好不要做某事。故应选C。

考点：考查动词不定式的用法。
