He has been a teacher for many years.
19、一般过去时通常与表示过去的时间状语连用 。如:yesterday, last week, two years ago, just now, in 2002 等 ; 而现在完成时贝U常与 just, already, ever, never 等副词和 these days, this week, since., for./since.ago/ up to now/so far等表示一段时间的状语 连用。(3 ) 一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作。说话的侧重点只 在于陈述一件过去的事情,不强调对现在产生的影响。如:He visited Guilin in 1998.他
20、1998年参观过桂林。(只说明去桂林的时间)(4)现在完成时表示 动作发生在过去,对现在造成了影响或产生了结果。不与确定的过去时间状语连用。一如:Jill has bought a new computer.吉尔买了一台新电脑。(着重点是现在有了一台新电脑)看看以下的几组句子,有什么区别?(A) Have you seen the film?(B)Did you see the film?说明你看过这部电影吗?句强调的是被问者对剧情是否了解;句强调的是看这部电影的动作是否发生过,并不强调是否知道其内容。(A) He has lived in Beijing for 8 years.
