这个题很有意思,很不错,很容易选错C.
这个题的正确答案是A
这个题的关键是句未的动词studied,是过去式,说明Robert已经不在国外学习了,已经完成了该动作,符合完成时态的定义.这个题如果把studied改为studies,那么这个题就选C,表示正在进行.
你问的问题,什么时候要用上been,这很简单,been+过去分词,表示被动语态的完成式.而题目中,是主动语态,不是被动语态,所以不用been.
Robert is said___abroad,but I don't know what country he studied in.
Robert is said___abroad,but I don't know what country he studied in.
a.to have studied
b.to study
c.to be studying
d.to have been studying.
这个是现在完成时么?为什么a选项不是to have been studied?什么时候要用上"been"这个单词的?
a.to have studied
b.to study
c.to be studying
d.to have been studying.
这个是现在完成时么?为什么a选项不是to have been studied?什么时候要用上"been"这个单词的?
