问题补充：

— The floor is dirty.

— Yes. It for two days.

A. hasn’t swept

B. didn’t sweep

C. hasn’t cleaned

D. hasn’t been cleaned

答案：

A. hasn’t swept

B. didn’t sweep

C. hasn’t cleaned

(答案→)D. hasn’t been cleaned

解析：考查情景交际和时态。句意：--地板很脏。--是的。已经两天没有打扫了。根据句意和for two days可知，应该使用现在完成时，排除B；floor和clean是动宾关系，应该使用被动语态，排除A、C；故选D。
