般过去时现在完成时主要用于:
1 、表示到现在为止这一时期中发生的动作或情况,即多次动作的总和。
e.g. We have learnt four English songs this month.
How many times have you read the novel?
For many days we haven`t seen each other.
2 、表示对现在有影响的某一已发生的动作。
e.g. The delegation has left 代表团已经走了
Look, what you have done. 看你干的事。
与这一时态连用的时间状语有:
already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短语,连词 since 引导的时间状语从句。
一般过去时与现在完成时的区别:
一般过去时:重在说明动作在过去发生时的具体情况。
现在完成时:只提起已发生的动作及其影响,不说明动作发生时的具体情况。
cf. Have you had your lunch?
What did you have for lunch?
I have ever been to the Great Wall,_and_I went there last summer with my father.
注:现在完成时表达的动作常具有反复性,故下面一句是错的:
Have you seen the six thirty`s news program?
应改为:
Did you see the six thirty`s news program?
