现在完成时的用法
现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。
We are good friends.(现在的情况）
I knew him in 1997.（过去的动作）
We have known each other since 1997.
（现在完成时把过去的动作和现在联系起来并着眼于现在）
She has been to Beijing.
(现在已不在北京，从结果上和现在联系起来）
She has been in Beijing for two years.
（现在仍在北京，从时间上和现在联系起来）
现在完成时的三种基本用法：
1、未完成用法。表示动作或状态开始于过去，一直延续到现在，可能继续发展，也可能刚刚结束。
He has been in the army for ten years.
I have studied English since 1980.
He has lived here all his life.
a.be,live,study都是延续性动词。
b.常用的时间状语：
since…,for…,in the past few years,so far,
all his life.
2、反复性用法，表示过去到现在这段时间
内反复发生的动作。

I have often wondered where she gets her money all these days.
这种用法从时间上与现在发生了联系。
3、完成性用法，表示动作或状态到说话时已经完成，通常所产生的结果把过去的动作和状态和现在联系起来。 He has gone to Shanghai.
他已经去了上海。（结果：他已不在这儿，He is not here now.）
