问题描述：
不定式的完成时和完成进行时
这两句话有什么区别?为什么用的时态不一样?
哪一个是正确的?
1 Robert is said to have studied abroad,but I don't know what country he studied in
2 He is said to be having been studied abroad for two years,but I don't which country he is in
另外我觉得最后应该是用 which country he is
第一个例子是曲一线上面的
不好意思第二个句子打错了
2 He is said to be having been studyding abroad for two years,but I don't which country he is in
