A. was
B. am coming
C. came
D. have come
答案:
A. was
B. am coming
C. came
(答案→)D. have come
解析:考查谓语动词时态的用法区别。常用表达方式:this/it is the first time后面跟定语从句,时态用现在完成时has/have done结构, 意思是第一次做某事; 当this/It is替换this was/It was时,即this/it was the first time后面也跟定语从句,但这时从句时态要用过去完成时had done结构;题干中是this is the first time 所以D正确。
