新概念英语第二册语法-现在完成进行时
1.构成:have / has + been + 现在分词
2.功能:
(1)表示从过去某时开始发生,一直延续到现在且可能延续下去
的动作。 (将此定义读 5遍)
. I've been waiting for an hour but she hasn't come.
. He has been running after her for 8 years.
(2)表某种感情色彩。
. I've been wanting to see you for so many years.
. Who's been telling you such nonsense.
现在完成时与现在完成实行时的对比:
现在完成时强调“结果”,而完成实行时强调“动作的延续”。
. I have thought of it.(我已想到了这个点。)
. I have been thinking of it.(我一直在想这个点。)
. Jim has painted the door.(杰姆已将门油漆过了。)
. Jim has been painting the door.(杰姆一直在油漆门。)
