Had they been expecting the news for some time``
问题描述:
Had they been expecting the news for some time``
可以看出这个句子是过去完成进行时```但是如果换成Have they expected the news for some time.怎么样``两个都可以翻译成他们期待了一段时间了吧``过去完成进行时``是说在过去某个时间之前```但是我不知道原句中这个"过去某个时间”谁能解释下``另外这两个句子有什么区别``
答
had they been doing强调的是过去某一时间的动作,have they done强调的是过去的某一时间的状态,我觉得哈~
