  1)It is the first / second time…… that…结构中的从句部分,用现在完成时。例如:
          It is the first time that I have visited the city. 这是我第一次访问这城市。
          This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。
          注意:It was the third time that the boy had been late.
          2)This is +形容词最高级+that…结构,that 从句要用现在完成时。例如:
          This is the best film that I've (ever) seen. 这是我看过的最好的电影。
          典型例题
          (1) ——Do you know our town at all?
          ——No, this is the first time I ___ here.
          A. was  B. have been  C. came  D. am coming
          答案B. This is the first time 后面所加从句应为现在完成时,故选B.
          (2) ——Have you ____ been to our town before?
          ——No, it's the first time I ___ here.
          A. even, come  B. even, have come  C. ever, come  D. ever, have come
          答案D. ever意为曾经或无论何时,反意词为never,此两词常用于完成时。
          注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
          (错)I have received his letter for a month.
          (对)I haven't received his letter for almost a month.
