三、 用法： 1) 现在完成进行时可以表示一个从过去某时
开始一直在进行并持续到现在的动作。这个 动作刚刚结束，对现在有影响。
• I'm tired because I've been running. 我很累因为我一直跑到现在。 （强调动作一直进行并持续到现在） 对比：I'm tired because I've run. 我累了因为我跑了。（强调动作已完成）

3)疑问句： Have/Has+主语+been+V-ing ? Yes, 主+have/has. No, 主+haven’t/hasn’t.
你一直在写一本小说吗？ Have you been writing a novel? 他一直给你写信吗？ Has he been writing letters to you?
在的一个动作；该动作有可能继续延续下去。
• I am reading the book. 现在正在读
进行时
I have read the book. 已经读过
• 完成时 I have been reading the book. • 现在完成进行时
过去到截 至说话为 止，一直
