现在完成进行时与一般过去时的区别：
　　(1) 现在完成进行时表示动作从过去某一时间开始，一直持续到现在，可能还要继续下去，侧重的是动作的持续进行。与for/since短语和since从句连用。
　　(2) 一般过去时只表示过去的动作和状态，和现在没有联系，只和表示过去的时间状语连用。如：yesterday, last Friday, three days ago, in 1998等。
　　I have been skating for five hours.
　　（一直都在滑，现在还在滑，有可能会继续滑下去）
　　I skated for five hours. （过去滑过5个小时，与现在无关。）
【达标拓展】
have been in, have gone to与 have been to 如何使用？
解答：三者都是现在完成时态。“have\has been in + 地点”表示某人在某处呆了多长时间；
“have\has gone to +地点”则表示到某出去了，人还未回来；“have\has been to +地点”
表示去过某处，现在已经回来了，不在那里了。例如：
He has been in Taiyuan for two years. 他在太原两年了。
He has gone to Taiyuan. 他去太原了。（现在在太原活在途中）
He has been to Taiyuan. 他去过太原。 (现在不在太原)
