在星期前用on,at noon是固定搭配，时间前用at,在季节前和月份前都是用介词in;
剩下的六个题都是考查特殊疑问词的用法，根据回答：She is a nurse.，可知道是询问职业，所以用What does she do ?（她是做什么工作的？）；根据回答she works in a hospital.可知道是询问地点，所以用Where does she work ?(她在哪工作？)；根据回答she usually takes the bus.可知道是询问方式，所以用How does she go to work ?(她怎样去上班)；根据回答It's a badminton racket可知道是询问物品，所以用：What is in your hand?（你手里的是什么？）根据回答：It's mine.可知道是询问物主,所以用Whose racket is this ?How do you get to your office from home?也是询问方式，你怎么样从家去上班？
