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 seen the film.
我看过这部电影。(现在我仍记得电影的内容)
I saw 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, yet, just, ever, never, before等副词以及“for+段时间”,“since+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 League for three years.
他入团已经三年了。
Tom wrote a letter to his parents last night.
昨晚汤姆给他的父母写了封信。
