Question

－Do you know our town at all?
－No, this is the first time I ________ here．

A．was

B．am coming

C．came

D．have come

Answer 1

D

试题分析：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。
