Who -----did you see yesterday afternoon?

Who -----did you see yesterday afternoon? who saw you?可以写成who did you see?吗　　他们有什么不同? did you see my who,whom are they talking about?还有who,whom did you see?答案上都用的whom,我觉得应该是who, who can you see Did you see the person_____new motorbike was stolen A.whom B.who C.which D.whose Who did you see at school yesterday?I_____Mike.在横线上填合适的词 Whom did you see?为什么用whom而不用who说清楚一点 我不懂 What animals did you see? Did you see the doctor? did you ever see snow? what ()did you see填空 when did you see just whah did you see just “Who did you meet there? Who did you go with? Who did you speak to? 白得的分本人英语很菜,You saw whom?可不可以改成 who did you see?
