选择题：Who's going to give me a talk at the meeting? A Mr King

这个问句是针对“将要演讲的人”提问的,所以完整的回答应该是：Mr King is going to give me a talk at the meeting.
实际上的日常交际当中,为简便起见,这一句会被省略一部分.省略后留下主语和助动词或系动词,这里就留下了is.
当句中没有is的时候,就要用其他助动词了.例如这一句：-Who gets up early,Tom or Bob?-Tom does.
若问题中的句子改成Who will give a talk at the meeting?,则答语变成：Mr King will.
