现在完成进行时的用法
现在完成时：
定义：
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）
We have known each other since 1997.
I knew him in 1997.
（过去的动作）
===
（现在完成时把过去的动作和现在联系起来并着眼于现在）
比较：
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。

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
