过去式几种表达的区别
I waited for an hour.
I had waited for an hour.
I had been waiting for an hour.
它们有什么不同?

I waited for an hour.我等了一个小时【等待已经结束,此刻等待了一小时,表示一个时间点】
I had waited for an hour.（until you got here) 我已经等了一个小时（直到你出现）【在过去的一段时间里,对过去的动作有影响】
I had been waiting for an hour.在过去的一个小时里我一直在等,（直到你出现）【更强调动作的延续】
后两者需要具体的语境,个人感觉过去完成时和过去完成进行时,前者强调结果【你出现了,所以我不用等了】,后者强调过程【等了一个小时那么久】

I waited for the train （for） over an hour. I waited （for） you (for） half an hour I have waited for May _____ half an hour _____ but she has n I have waited for you since half an hour ago 此话成立吗,意思是? she has been wait for an hour she has waited for an hour 二者的 i danced for an hour. We had waited for Jane for an hour before she ______. We waited over an hour for the train.【同义句转换】 We waited for - I waited for the rain to stop .After two hour,I came bake ho 改错题I waited for the rain to stop.After two hour,I came back She has waited for Daniel for half an hour?（对for half an hou They have waited here for half an hour的同义句
