---The window is dirty.
----I know. It ______ for weeks.
A．hasn’t cleanedB．didn’t clean
C．wasn’t cleanedD．hasn’t been cleaned
D

試題分析：考查時態(tài)和語態(tài)。結(jié)合上下文可知用現(xiàn)在時態(tài)，從時間狀語for weeks可知使用現(xiàn)在完成時，并且window與clean之間為被動關(guān)系，故選D答案。句意：——窗戶臟了�！抑溃呀�(jīng)幾個星期沒有清潔了。
點評：時態(tài)和語態(tài)是高考�？純�(nèi)容。時態(tài)題的考查要注意關(guān)鍵詞，同時要注意具體語境。
