M: I want to have a new dentist since my dentist is going to leave the country. You said you know Dr. Anderson. Do you recommend him?
W: Well, I just saw him only once. But I could say nothing more about him except that he wears very sharp glasses.
Q: What does the woman imply?
正确答案：B
解析：男士说自己要找一个新的牙医，问女士是否推荐Dr. Anderson。女士说自己只记得他的眼镜很时髦，除此之外，没有什么好说的，意思就是不推荐这个牙医。故答案是B。对话中，当男士问女士是否推荐Dr. Anderson时，女士并没有给出Yes或No的回答，属于“答非所问型”对话，答话人往往表达的是否定的语意。

W: Oh, really? I joined a Yoga club a year ago and went from 65Kgs to present 49Kgs. I expected to give up halfway.
Q: What do we know about the woman?
正确答案：A
解析：女士解释自己焕然一新的原因是一年前加入瑜伽俱乐部，使体重下降，故答案为A。She选项题，女士的话是听音重点。由选项提示词lose weight，Yoga，figure shaping可推测话题与瑜伽减肥有关。仔细听音，即可准确答题。
