have done 与have been doing的区别?
两者好像都有可以延续到过去的意思?我知道have been doing 肯定有,比如句子
i have lived in U.S.for 2 months
i have been living in U.S.
两者好像没有区别啊,出选择题的话应该怎么选.
如果第一句改成i have lived in U.S since 2009.意思是我从2009年开始就住在美国，今后也会在美国的意思。那和第二句用法基本一样？第二句的意思简单明了我今后还会住在美国，

have done 是指发生在过去的事情,对现在又影响
have been doing 是指发生在过去并且现在仍在继续的事情

have been doing 表示一直。。动词要用延续性动词
have done 表示：已经。。短暂性动词也可以有完成时。
