現(xiàn)在完成進行時：1.構(gòu)成：have / has + been + 現(xiàn)在分詞2.功能：(1)表示從過去某時開始發(fā)生，一直延續(xù)到現(xiàn)在且可能延續(xù)下去的動作。 (最好將此定義讀 5遍)

►. I've been waiting for an hour but she hasn't come.

►. He has been running after her for 8 years.(2)表某種感情色彩。

►. I've been wanting to see you for so many years.

►. Who's been telling you such nonsense.現(xiàn)在完成時與現(xiàn)在完成進行時的對比：

現(xiàn)在完成時強調(diào)“結(jié)果”，而完成進行時強調(diào)“動作的延續(xù)”。
