问题补充：

— I’ve just been to my first language class.

— Oh really? . Which language are you studying?

A. So do I

B. So have I

C. So I do

D. So I have

答案：

A. So do I

(答案→)B. So have I

C. So I do

D. So I have

解析：句意：我刚上了我的第一次语言课。真的？我也是。你在学哪种语言？某人也怎样用so+助动词/系动词/情态动词+另一主语。I’ve just been to my first language class用的助动词have，下文也用have。选B。
