我看过这部电影。(现在我仍记得电影的内容)
I saw2 the film three days ago.

格林先生昨天买了一台新电脑。(强调的是格林先生买新电脑的时间是昨天)
2. 时间状语不同
现在完成时常与already, yet4, just, ever5, never, before等副词以及“for+段时间”,“since6+过去时间/从句”等时间状语连用;而一般过去时则常与“段时间+ago”,just now, yesterday, last week等表示过去时间的状语连用。例如:
She has lived here since two years ago.
她两年前就住在这里了。
She lived here two years ago.
两年前她住在这里。
