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?
正确答案：B
解析：题目询问Frank打算做什么，显然是问将来的事。关键是要听到男士最后一句话中提供的信息“现在我回到学校学习，以获得教师资格证书。”与B相符，且时态合理，故B为答案。A中的move和D中的work在对话中都是过去的事，所以不正确；C中的go back与对话中“here I am, back in school”所表达的现状也不符。

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?
正确答案：D
解析：建议题。本题关键在于抓听女士说的“你为什么不辞职来替我送花呢？”D中的leave his job与对话中的quit同义；对话中的deliver flowers for me在D中概括为work for her。deliver flowers是替女士给客户送花，不是C中bring her flowers（送花给该女士）的意思。A中的quit delivering“停止送”与对话不符。男士现在就在一家餐馆工作，B说的是现状，故不正确。
