求助一道初二英语题

has been 是曾经去过某地，现在回来了
has gone 是已经去了某地，去那里没回来
been in 是加地点，并一直在那
been to 只说去了一下
完成时分 现在~have done ，过去~had done 一般将来~will have done
过去将来~would have done

He has gone to NY 现在~
I hadn't learned any English before I came here过去~
By the time you get home I will have cleaned the house from top to bottom.一般将来~
my father hoped that by my 20 I would have found a good job过去将来完成时(不太常用，一般事态题不考，有时用于虚拟语气，主句用它，表示与过去事实相反）

其实总的来说完成时的区别就是表示的时间不同

has been 是曾经XX，现在回来了 一般这样
如 I have been in NY for 4 years

has gone 去那里没回来
He has gone to NY and will come back in 3 weeks

完成时包括现在完成时。
现在完成进行时 have been dong
一般是有点过去在做一直做到现在的意思
现在完成时 have done
