Question

【题目】—The room is dirty.

—Sorry, It ______ for weeks and I will do it now.

A.hasn’t cleanedB.hasn’t been cleaned

C.wasn’t cleanedD.didn’t clean

Answer 1

【答案】B

【解析】

考查被动语态和主谓一致。句意：——房间很脏。——对不起，已经几个星期没打扫了，我现在就打扫。此处It是句子主语，指的是the room，和clean之间是被动关系，再根据for weeks和now可知句子用现在完成时态的被动语态结合句意，因此用hasn't been done。故选B。
