“have studied”表示过去发生的动作对现在造成的影响或结果;“have been studying”强调动作从过去开始一直持续到现在并且还在进行;“studied”是一般过去时,只表示过去的动作;“was studying”是过去进行时,表示过去某个时间正在进行的动作。这里强调学习英语这个动作持续了两个小时并且还在继续,所以用现在完成进行时。
A。在这道题中,A 选项“have been studying”是现在完成进行时,强调学习英语这个动作持续了一个小时并且可能还在继续。B 选项“studied”是一般过去时,只表示过去的学习动作。C 选项“have studied”是现在完成时,重点在对现在的影响。D 选项“studies”是一般现在时,不符合句子的时间状语。综上,答案是 A 选项。
