W: Frank, I thought you were working in New York.
M: I was. But I've moved back. I just couldn't get used to living in a big city. So here I am, back in school, taking courses for a teacher's certificate.
Q: What is Frank planning to do?
正確答案：B
解析：題目詢問Frank打算做什么，顯然是問將來的事。關鍵是要聽到男士最后一句話中提供的信息“現在我回到學校學習，以獲得教師資格證書。”與B相符，且時態合理，故B為答案。A中的move和D中的work在對話中都是過去的事，所以不正確；C中的go back與對話中“here I am, back in school”所表達的現狀也不符。

M: Washing dishes in the restaurant every day is really boring.
W: Why don't you quit and deliver flowers for me?
Q: What does the woman advise the man to do?
正確答案：D
解析：建議題。本題關鍵在于抓聽女士說的“你為什么不辭職來替我送花呢？”D中的leave his job與對話中的quit同義；對話中的deliver flowers for me在D中概括為work for her。deliver flowers是替女士給客戶送花，不是C中bring her flowers（送花給該女士）的意思。A中的quit delivering“停止送”與對話不符。男士現在就在一家餐館工作，B說的是現狀，故不正確。
