比较过去时与现在完成时

1）过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。

2）过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。

一般过去时的时间状语:

yesterday, last week，…ago, in1980, in October, just now, 具体的时间状语

共同的时间状语:

this morning, tonight,this April, now, once，before, already, recently，latel y

现在完成时的时间状语

for, since, so far, ever, never, just, yet, till / until, up to now, in past y ears, always,

不确定的时间状语

3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know.

过去时常用的非持续性动词有come, go, leave, start, die, finish, become, g et married等。

举例：

I saw this film yesterday.

（强调看的动作发生过了。）

I have seen this film.

（强调对现在的影响，电影的内容已经知道了。）
