摘要： Mary to see you . She for you downstairs at the moment . A. has come ; is waiting B. came ; is waiting C. has come ; waited D. came ; was waiting 答案是A项.思考这道题时应该使用逆向思维.即先考虑第二个空白处的选项.再考虑第一空白处的答案.因为第二句中交代了一个重要的时间状语:at the moment .因此应毫不犹豫地选择is waiting这一现在进行时的时态.据此第一句的句意也就随之清晰起来?quot;玛丽已经到这儿来看望你"很明显对表示对现在造成影响的动作要使用现在完成时态.
