现在完成时和一般过去时所表示的动作都是发生在过去,所以在实际运用中就有很多同学混淆二者的用法。现在我们就一起来看看现在完成时和一般过去时的区别。

  1. 侧重点不同

  现在完成时和一般过去时所表示的动作都发生在过去,但它们所强调的重点不同:现在完成时侧重于对现在的影响;而一般过去时侧重于某一动作发生在过去某个时间或某段时间,即现在完成时侧重于现在的结果,而一般过去时侧重于动作发生的时间。例如:

  I have seen1 the film.

  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.

  三天前我看了这部电影。(强调是三天前,而不是别的什么时候看的电影)

  Mr Green has bought a new computer.

  格林先生买了一台新电脑。(着重点是格林先生现在有了一台新电脑)

  Mr Green bought a new computer yesterday.

  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。

  He has been in the League7 for three years.

  他入团已经三年了。

  Tom wrote8 a letter to his parents last night.

  昨晚汤姆给他的父母写了封信。
