问题补充:
This is the third time I Beijing. The second time I here was on Christmas Day last year.
A. have visited; came
B. have visited; have come
C. visited; came
D. visited; have come
答案:
(答案→)A. have visited; came
B. have visited; have come
C. visited; came
D. visited; have come
解析:考查句型:This is the third time后跟从句用现在完成时态,The second time为连词,根据时间last year,应用过去式,所以选A,句意:这是我第三次参观北京了。第二次我来的时候是去年的圣诞节。所以选A。
