have been doing 和have+过去分词有什么不同?
RT 比如have been collecting 和have collected的不同之处

1 现在完成进行时,表示过去发生的动作或已经完成的动作,现在仍然继续,并且还将进行下去.构成结构是：“have been +doing”
2 现在完成时,表示过去发生的动作对现在造成的结果和影响.结构是：“have+过去分词”
3 这两种时态的区别是：现在完成进行时表示动作还将继续并进行下去,表示动作继续.而现在完成时表示动作已经结束.
For example,I have been collecting old coins for three years.(我已经收集古币三年了,说明现在还收集.)
I have collected old coins for three years.(说明只收集了三年,现在不收集古币了)
