用法要点
1.现在完成时不能单独与准确时间连用,（如表示过去的时间状语）
如yesterday(morning、afternoon),last(morning、afternoon）等,除非与for,since连用.
2.现在完成时往往同表示不确定的过去时间状语连用
如already（肯定,句中）,yet（否定,疑问,句中）,just,before,recently,still,lately,never等：
He has already obtained a scholarship.
I haven't seen much of him recently (lately).
时态
We have seen that film before.
Have they found the missing child yet?
3.现在完成时态经常与表示频度的时间状语连用,如often,sometimes,ever,never,twice,on several occasion等：
Have you ever been to Beijing?
I have never heard Bunny say anything against her.
I have used this pen only three times.It is still good.
George has met that gentleman on several occasions.
4.现在完成时还往往可以同包括现在时间在内的时间状语连用
如now,up to these few days/weeks/months/years,this morning/week/month/year,just,today,up to present,so far等：
Peter has written six papers so far.
Up to the present everything has been successful.
5.现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作.
6.现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束.
例如：Have you found your pen?你已找到你的钢笔了吗?
7.现在完成时的"未完成用法"指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续下去.
例如：I have heard nothing from him up to now.到目前为止我没有他的任何消息
注意：（1）现在完成时的未完成用法只适用于延续性动词,不可用于终止性动词,即瞬间完成或延续时间很短的动词.如：come,go,arrive,leave,join,become,die等.
8.一段时间+has passed+since从句
9.现在完成时常和短语 "up to now /till now","so far" （意思是从过去某一确定的时间一直延续到现在)连用.
Up to/till now he's read many story books.至今他已读过好多故事书.
I've been to New York three times so far.至今我已到纽约去过三次.
has gone (to),has been (to),has been (in) 的区别.
has gone to：表示某人已去了某地,而没有回来,说话时人不在原地（去了没回）.
has been to ：表示去过某地,说话时人不在某地（去过已回来）.
has been in：表示一直呆在某地,常与时间段搭配（呆了很久）
10.不可以与一般过去时的定义混淆
