六．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。）
