W: Professor Neon, a few of us at the back didn't get the copy of your reading assignment.

M: Congratulations, Li Ming. You're the talk of the town and the pride of our class now.
W: If you are referring to my winning the English speech contest, I don't think it such a big deal. You know, I've spent two summer vacations learning English in Canada.
Q: What do we learn about Li Ming from the conversation?
正确答案：B
解析：男士恭喜女士成了小镇上的名人和班上的骄傲，女士说“我认为这没什么了不起的”，说明她很谦虚，因此B为答案而A错。C错在two years；选项D所说的与女士的实际态度恰好相反，她是班级的pride，不是说她很proud。
