新概念英语第二册语法总结:现在完成进行时

2012-01-14来源:和谐英语

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。 (最好将此定义读 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进行时的对比:
现在完成时强调“结果”,而完成进行时强调“动作的延续”。
?. I have thought of it.(我已想到了这一点。)
?. I have been thinking of it.(我一直在想这一点。)
?. 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。)
