6. 怎樣正確理解現在完成時

You don’t need to describe her. I ______ her several times.

A. had met               B. have met             C. met                     D. meet

此題應選 B。主要考察現在完成時的用法。現在完成時是各類考試的常考考點, 其基本用法有兩種：

一、持續性用法(或叫未完成用法)：指的是動作過去發生, 但在過去并未完成, 而是從過去一直持續到現在。此時多半有表示持續性的時間狀語(如for 5 years, since 1990)。

二、影響性用法(或叫已完成用法)：指的是動作過去發生, 且在過去已經完成, 但這個過去發生的動作對現在有影響, 且說話者正好要強調的就是這個影響。現在完成時的這個用法, 一般沒有明顯的時間狀語, 主要通過上下文來理解。

1. —Where ___ the radio?I can’t see it anywhere.

—I ___ it right here. But now it’s gone.

A. did you put; have put

B. have you put; put

答案：1. B 2. D

7. 過去進行時用法一得

I don’t think Jim saw me; he ______ into space.

A. just stared           B. was just staring   C. has just stared     D. had just stared

此題應選B。主要考察動詞過去進行時的基本用法(即動作在過去某一時刻正在進行)。此題的上文設置比較巧妙：前面的主句用了I don’t think(指現在的看法), 而其后的賓語從句用的是saw(指過去的動作), 也就是說此題的語境是：現在談論過去的情況, 全句意為：我認為吉姆當時沒看見我, (因為)他當時正在朝天空看。
