I have been sitting here for three hours.我在这坐了三小时.可否说成I sat here for three hours?
也就是去掉have been,把 sitting改成过去式,意思是不是一样?

不能那么说,因为前面的是现在完成进行时,表达的意思是一直在那里坐着,已经坐了三小时.坐的动作是延续的,正好对应延续性时间状语for three hours
而sat是一般过去时,只能表示作的动作发生在过去,而且是不延续的,不能跟延续性的时间状语.
再问：那么说I sat here for three hours这句话语法也错误了?不能加for吗?谢谢
再答：是啊不过是不能加 for three hours 这是一个整体
