單元語法總結
複習動詞時態：現在完成進行時
現在完成進行時表示動作從過去某一時間一直持續到現在或離現在不遠的時間，其動作是否持續下去，則由上下文決定。
(1)敘述某一動作從過去開始，一直持續到現在，仍在繼續之中或剛剛停止。常與for,since, all morning/day/week等狀語連用。
The telephone has been ringing for almost a minute. Why doesn't someone answer it?
(2)表示重複的動作。有時現在完成進行時表示的動作並不是一直不停地進行，而是在斷斷續續的重複。
—We've spent too much money recently.
—Well,it isn't surprising. Our friends and relatives have been coming around all the time.
(3)表示“剛才、近來”發生的動作，一般不再繼續，此時一般通過上下文語境來判斷。
She has been sweeping the street allday. She is too tired.
(4)帶有濃重的感情色彩，強調持續了“那麼久”或做得“那麼辛苦”。
Oh,you've come at last! I have been waiting for you for two long hours.
