单选题ThefirsttimeI________here,itwast

单选题 The first time I ________ here, it was the year of 1980; this is the third time that I _________ to ChongqingA.came; had visitedB.had come; visitedC.came; have visitedD.had come; have visited

C解析考查固定句型：第一空是过去时，因为the first time引导的时间状语从句，和主句一致，第二空填现在完成时，句型是：This Is the first/second/third time+从句，从句中用现在完成时，第二空填过去时，句意是：--我第一次到这儿是在1980年。--这是我第三次到重庆。选C。

这个解释是对的
