15. W: This apartment has three bedrooms and a bath. Here's the kitchen.
M: It seems a little small to me.
Q: How many rooms are there in the apartment?
解析：B。女士說，“這套公寓房有三間臥室、一間浴室和一間廚房”，一共是5個房間，所以選B。bath即bathroom，kitchen即炊事房，也應看作“room”。數字題，一般需要簡單的計算，往往“聽到什么（數字）就不選什么”。本題只要把bath和kitchen看做room就能做對。

16. M: This is a good seat. I'm glad you suggested the move. Here in the front section we can look out and enjoy the scenery. If you get seat in the middle of the plane, the wings block your view.
W: Feel the plane moving? Are we taking off now? Listen. The girls are giving instructions.
Q: What can be inferred from the conversation?
解析：C。男士說：“這個位置真好。真高興你建議換座位。在這里，坐在前面，我們可往外看風景。要是坐在飛機中部，機翼就把視線擋住了。”因此他們開始是坐在飛機中部的，C正確。
