英语语法,非谓语动词上的问题
when asked to compare the education systems of china and britain,the professor gave his own comment
这里为什么要用“asked to compare”而不是“asked him to compare”?
答
when （he was） asked to compare the education systems of china and Britain,the professor gave his own comment.
省略了he was是他被问及……
改成主动句时才是你说的那个结构
