1.--What a nice classroom! --It ____ every day.
A. is cleaning B. has cleaned C. must clean D. is cleaned
解析：推测这句话的意思应该是“它每天都被打扫”，考查被动语态的结构be + 动词的过去分词。因此答案应该选D。
2.I know Beijing well. I ____ there three times.
A .will go B. have been C. went D. have gone
解析：推测这句话的意思“我很了解北京，我去过那三次”。表示去过应该采用的时态是现在完成时，因此可排除A和C，区别have been和have gone,have been 去过；have gone 去了（还没回来）。因此应该选择B。
