知識點講解：

表示一個持續(xù)到現(xiàn)在的動作(這動作可能剛停止，也可能還在進行)。
(1) 構(gòu)成：have been doing
(2) 用法：
1) 延續(xù)：表示開始于過去的活動持續(xù)到現(xiàn)在，并且活動往往還沒有結(jié)束，將繼續(xù)持續(xù)下去。

我在夏威夷已經(jīng)生活了十年。

What happened to you? Have you been crying?

2) 重復：到目前為止的一段時間內(nèi)重復發(fā)生的活動。

I have thought it over.
我已經(jīng)考慮過了。(影響：現(xiàn)在可以給回復)
I have been thinking it over.
我一直在考慮這件事。(還未考慮清楚)
2) 現(xiàn)在完成時經(jīng)常表單個事件，現(xiàn)在完成進行時可表重復事件.

Juice has been meeting a hot girl in the library lately.
橙汁近來經(jīng)常在圖書館遇到那個性感的女孩。
3) 現(xiàn)在完成時陳述事實，現(xiàn)在完成進行時表感情色彩.
What have you done?
你做什么了？(僅是問問)
I've been waiting more than 30 years to say this: “Dad, I always told you I'd come back and get my degree.”
在2007年6月7日舉行的哈佛大學的畢業(yè)典禮上，Bill Gates獲得了學校頒發(fā)的榮譽博士學位時說道：
我已經(jīng)等了30多年才得以說這句話：“老爸，我一直都在告訴你，我會回來拿到學位的”。(難以抑制的興奮之情)
Where have you been? I have been waiting for you in the rain for two hours.
你去哪了？我在雨中等了你兩個小時。(不滿)
4) 表重復時：完成時強調(diào)成果，講次數(shù)；完成進行時強調(diào)持續(xù)，不講次數(shù)。
