中考英語動詞時態復習

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意為曾經或無論何時，反意詞為never，此兩詞常用于完成時。

注意：非延續性動詞的否定形式可以與表示延續時間的狀語連用。即動作不發生的狀態是可以持續的。

（錯）i have received his letter for a month.

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

11.12 比較since和for

since 用來說明動作起始時間，for用來說明動作延續時間長度。例如：
i have lived here for more than twenty years.我住在這兒二十多年了。
i have lived here since i was born. 我從出生起就住在這兒了。
注意：并非有for 作為時間狀語的句子都用現在完成時。
i worked here for more than twenty years. （我現在已不在這里工作。）
i have worked here for many years.（現在我仍在這里工作。）
注意：用句型轉換的方法，很容易排除非延續動詞在有for/since結構的完成時中的誤用。
1）（對） tom has studied russian for three years. = tom began to study russian three years ago, and is still studying it now.
2）（錯） harry has got married for six years. = harry began to get married six years ago, and is still getting married now.
顯然，第二句不對，它應改為 harry got married six years ago. 或 harry has been married for six years.

2） since +一段時間+ ago。例如：

great changes have taken place since you left. 你走后，變化可大了。

great changes have taken place since we were here. 我們走后，變化可大了。

11.14 延續動詞與瞬間動詞

1） 用于完成時的區別

延續動詞表示經驗、經歷； 瞬間動詞表示行為的結果，不能與表示段的時間狀語連用。例如：

he has completed the work. 他已完成了那項工作。 （表結果）
