he_____a company abroad for three years,and now he is teaching in Shanghai.A had run B has runC would runD ran为什么选D啊,不可以选B吗?说明原因
真心不可以,我的朋友!
因为B是现在完成时,表示过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态.
后面一句中说他在上海工作,和前面的他开三年公司没有什么关系,也不是要重点说明“开公司”的行为还要持续或对现在有什么影响,所以只需要陈述一下事实就可以了,单纯的说他开公司这件事,一定选D.

D and now he is teaching in Shanghai. 现在他在上海教书。
所以在国外经营公司三年是过去的事实。所以用一般过去时。这个考点在高考中现在经常考到。
