问题描述：

-___ these books ___well?-No,none of them has sold out yet.
A.Were;sold B.Have;been sold C.Are;sold D.Are;selling
为什么不能选C呢?

答

sell well 是“销售得好，卖得好，畅销”的意思。用主动语态表达。正常语序是These books are selling well.

答

C是被动语态,但是sell well,这是一个固定用法,具体说来是：动词+副词没有被告动语态,所以ABC全是被动语态,A是一般过去时的被动语态,B是现在完成时的,C是一般现在时的,只有D不是被动语态,只能选择它.
