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
| A |
解析
| 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 (现在)，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。 |
