Simple past tense and present perfect tense
There are some differences between the simple past tense and present perfect tense.
·We use the simple past tense to tell what happened in the past.
e.g. Daniel went to Beijing two years ago.
We use the present perfect tense to talk about an action that started in the past and continues to the present.
e.g. Daniel has lived in Beijing for two years.
·We use the simple past tense to tell what happened in the past.
e.g. Daniel bought a new computer last month.
We use the present perfect tense to talk about the result of an action. When the action happened is not very important. It may have just happened or happened some time ago.
e.g. Daniel has bought a new computer. (Daniel has a new computer now.)
与一般过去时的用法比较
一般过去时谈论发生在过去的动作和事情。
我们用现在完成时谈论的过去发生的一个动作对现在造成的影响或结果。（动作什么时候发生并不重要，也许是刚刚发生，也许是一段时间之前就发生。）
·We use the simple past tense to tell what happened in the past.
e.g. Mr Wu visited Canada in 2010 and 2011.
We use the present perfect tense to tell how many times an action has happened till now.
e.g. Mr Wu has been to Canada twice.
与一般过去时的用法比较
我们用一般过去时谈论发生在过去的动作和事情。
我们用现在完成时谈论的是一个到现在为止已经发生多次的动作。
We often use these time expressions with the simple past tense: yesterday, the other day, last..., ... ago, just now.
We often use these time expressions with the present perfect tense: already, ever, just, recently, yet, so far, up to now, till now, for ..., since ..., in the last/past ten years.
与一般过去时的用法比较
常与一般过去时连用的典型的表示过去时间的状语（具体的）：
yesterday（昨天），the other day（前两天），just now（刚才），时间+ago，last+时间等；
常与现在完成时连用的典型的时间的状语（模糊的）：
already, just, ever, never, yet, recently, over, before, since, for, ...
