新概念英语第二册语法总结:现在完成进行时

By 网友发布 2015年01月23日

  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。 (*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。)
