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）

. 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 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。）
