53 現(xiàn)在完成進行時與現(xiàn)在完成時的比較（二）　Track 053

完成進行時強調(diào)動作的過程，完成時強調(diào)動作的結(jié)果。
現(xiàn)在完成進行時所強調(diào)的是在過去一段時期內(nèi)某項活動的持續(xù)性，因此強調(diào)的是動作本身?，F(xiàn)在完成時則是強調(diào)動作的結(jié)果。
a. My hands are very dirty. I’ve been painting the house.
我的手很臟，我一直在給房子刷漆。
b. I have painted the house green.（The house was white, but now it’s green.）
我把房子刷成了綠色。
c. Sorry about the mess—I’ve been painting the house.
（painting活動還沒有結(jié)束，房子還沒有收拾，所以屋子很亂。）
d. I’ve painted two rooms since lunchtime.
（painted的結(jié)果是“兩間房子都已粉刷完畢”。）
e. I have been reading your grammar book. After I finish it,I’ll discuss some problems with you.
f.I have read your grammar book and I have questions to ask you.
g. I have been reading the book you lent me but I haven’t finished it yet.
h. I have read the book you lent me, so you can have it back now.
i. — Oh, I have been sitting in the same position too long. My legs have fallen asleep.
噢，我一個姿勢坐得太久了，兩條腿都麻木了。
—Shake it a little before you get up.
站起來之前，你先把腿抖一抖。
從上一句我們可看出：由于長時間持續(xù)地坐著 (have been sitting)，造成的結(jié)果是My legs have fallen asleep。因此，完成進行時表示活動的延續(xù)性；完成時強調(diào)動作的結(jié)果。
