— The floor is dirty.
— Yes. It _______ for two days.
A．hasn’t sweptB．didn’t sweepC．hasn’t cleanedD．hasn’t been cleaned
D

試題分析：考查情景交際和時(shí)態(tài)。句意：--地板很臟。--是的。已經(jīng)兩天沒有打掃了。根據(jù)句意和for two days可知，應(yīng)該使用現(xiàn)在完成時(shí)，排除B；floor和clean是動(dòng)賓關(guān)系，應(yīng)該使用被動(dòng)語態(tài)，排除A、C；故選D。
