内容预览

I have already taught him some English.

John has never been to the space museum.

My boy has just started junior high school.

现在完成时常与时间副词already, never, ever, just, before, yet等连用。

比较：He has been to Beijing.

他曾去过北京。

（人已回来，可能在这儿）

He has gone to Beijing.

他已经去北京了。

（人已走，不在这儿）

have / has been (to) 表示“曾经到过某地”，说话时此人不在那里，已经回来。侧重指经历。

have / has gone (to) 表示某人“已经去某地了”，说话时此人可能在路上或已到那里，反正不在这里。

比较：I have seen the film.

(我了解这部电影的内容)

I saw the film last month.

我上个月看了这部电影。

(只说明上星期看了这部电影，不

涉及现在的情况)

① 一般过去时只强调过去的动作；现在完成时强调过去的事情对现在的影响。

② 一般过去时通常与表示过去的时间状语连用；现在完成时则不能与表示过去的时间状语连用。

③ 一般过去时单纯表示过去的经历；现在完成时表示过去的动作或状态延续到现在并可能持续下去。

一般过去时的时间状语有：yesterday, last week, … ago, in1980, in October, just now …
