Question

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

Answer 1

A

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。
