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。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中,从句要用完成时。
  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.
