M: You'll need 36 credit hours to get an M.A. degree. Fifteen must be from the English Department and fifteen from the Education Department. For the remaining six credit hours, you can either write a thesis or take two more optional courses.
W: Right now, this is very confusing to me, but I'm sure I'll know what to do as I learn more about it.
Q: What are they talking about?
正确答案：C
解析：主旨题。国个选项都是名词或动名词短语，预读可知，问的是谈话的主题。男士说需要36学分才能获得文学硕士学位，接着作了详细说明，故选C。B的涉及面太广，他们只谈到了学分要求，并没有谈其他方面；A是无中生有，D属于原词干扰。

M: You call Henry a dreamer, but I think he's got a lot of good ideas.
W: Well, good ideas are only useful if you make something out of them. I don't think a day-dreamer can be a good entrepreneur.
Q: What does the woman think of Henry?
正确答案：C
解析：语义理解题。关键是听到女士说的“只有从中有所得的想法才能称之为好的想法”，言外之意即Henry没有将想法付诸实践。故选C。
