　　用于現(xiàn)在完成時(shí)的句型

　　1）It is the first / second time.... that…結(jié)構(gòu)中的從句部分，用現(xiàn)在完成時(shí)。例如：

　　It is the first time that I have visited the city. 這是我第一次訪(fǎng)問(wèn)這城市。

　　This is the first time （that） I've heard him sing. 這是我第一次聽(tīng)他唱歌。

　　注意：It was the third time that the boy had been late.

　　2）This is +形容詞最高級(jí)+that…結(jié)構(gòu)，that 從句要用現(xiàn)在完成時(shí)。例如：

　　This is the best film that I've （ever） seen. 這是我看過(guò)的最好的電影。

　　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(yīng)為現(xiàn)在完成時(shí)，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(wú)論何時(shí)，反意詞為never，此兩詞常用于完成時(shí)。

　　注意：非延續(xù)性動(dòng)詞的否定形式可以與表示延續(xù)時(shí)間的狀語(yǔ)連用。即動(dòng)作不發(fā)生的狀態(tài)是可以持續(xù)的。

　�。ㄥe(cuò)）I have received his letter for a month.

　�。▽�(duì)）I haven't received his letter for almost a month.
