【—語法輔導之現(xiàn)在完成時】以下是對用于現(xiàn)在完成時的句型知識的介紹，希望同學們認真學習。

　　用于現(xiàn)在完成時的句型

　　1）It is the first / second time.... that…結構中的從句部分，用現(xiàn)在完成時。例如：

　　It is the first time that I have visited the city. 這是我第一次訪問這城市。

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

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

　　2）This is +形容詞最高級+that…結構，that 從句要用現(xiàn)在完成時。例如：

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

　　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。

　　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。

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

　　（對）I haven't received his letter for almost a month.
