----- The windows must have taken you quite a long time that day.
----- Right. They ______ for months.
A．haven’t been cleanedB．didn’t cleanC．hadn’t been cleanedD．haven’t cleaned
C
考查時(shí)態(tài)。根據(jù)must have taken可知是過去的某個(gè)時(shí)間擦窗戶的，那么窗戶很久沒有被擦是在這之前，所以使用過去完成時(shí)。句意：—那些窗戶一定花了你很長時(shí)間吧！—是的。他們已經(jīng)好幾個(gè)月沒有被擦了。
