关于打电话时用语的一道选择题
Boy:hellp!Could I speak to Harry,Please?
Girl:He's not here at th moment,______?
A.Who speaks B.Who are you C.Who's that speaking D.What's that speaking
why?谁能详细的分析一下ABD为什么不对.并告诉下还能怎么回答girl.
我的意思是还能有什么话和“Who's that speaking ”意思相同在电话中。
另外，Who's that speaking?speaking作为现在分词定语修饰that吗？

Answer 1

A时态错,应为who is speaking.
B错,打电话和敲门一样,不能直接称呼对方you,此为英语基本常识,无法解析为什么不能这样用.
D虽然不能用you,但可以用who,不能用what,此为常识.
另外可用的代替语：who is this?
who is speaking?
speaking作为现在分词定语修饰that,that可省略.
