Question

一道初中英语选择题，求高手解释,到底是考察电话用语还是考察it指代前一个事物？到底是C还是D？求详细解释

-John， someone in your class phoned you this morning.
-Oh, who was __________?
A. he B. she C. it D. that

Answer 1

D ,电话用语中问对方是谁都是用“Who is that”,不知道是男女，所以A,B排除，it不指人

Answer 2

C
这里一定用it。再如，有人敲门，你问Who is it? 是谁啊？只有两个人互相通电话时才用that。如：
Hello. Mary speaking. Who's that?

希望对你有帮助

Answer 3

C，电话中的一般用it代替

Answer 4

A

Answer 5
