  英语时态是英语语法中的第一道难关,攻下此难关是作文、阅读、口语之关键。汉语用不同词表达相应时态,而英语用同一词的不同变化形式表达时态。

  现在完成进行时:have / has + been + 现在分词

  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.(run after: 追求)

  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.

  释惑要点: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。)
