?
1)It is the first / second time…. that…結(jié)構中的從句部分,用現(xiàn)在完成時。
  It is the first time that I have visited the city.
  It was the third time that the boy had been late.

2)This is the… that…結(jié)構,that 從句要用現(xiàn)在完成時.

典型例題
(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 后面所加從句應為現(xiàn)在完成時,故選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意為曾經(jīng)或無論何時,反意詞為never,此兩詞常用于完成時。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中,從句要用完成時。
  注意:非延續(xù)性動詞的否定形式可以與表示延續(xù)時間的狀語連用。即動作不發(fā)生的狀態(tài)是可以持續(xù)的。
(錯)I have received his letter for a month.
(對)I haven't received his letter for almost a month.
