1.have been doing sth表示的是过去某个时间就开始做的事情，且一直持续到说话这个时刻这件事仍在继续并将一直继续下去。
eg:I have been learning English for 12 years.我学英语已经12年了（12年前开始学，现在还在学，并且还将继续学）
2.have done 表示的是过去做的事情，到说话的这个时刻，这件事已经完成了。一般可搭配already这个副词，来强调已经结束。而否定句里则和yet搭配
eg: I have already went to the post office.我已经去过邮局了（表示在说话的时候，我已经从邮局回来了。潜台词是要去邮局办的事情已经都做完了。）
I have not finished the homework yet.我还没做完家庭作业（说话时，作业尚未写完。潜台词即我不能做其他事情，因为作业还没写完）
have doing 的搭配不存在，是个错误用法。
