M: Ouch, how can the sand be so hot when the water’s still cold? My feet feel like getting burnt
W: [12]Now, Mark, were you sleeping when professor Brock gave that lecture on specific heat in physics class?
M: I didn’t come to San Diego on spring break to talk about professor Brock’s physics class.
W: I know, me neither. I was just answering your question, that’s all.
M: What question?
W: You weren’t even paying attention to your own question
M: I was just complaining about the hot sand Considering what the water’s like, I wonder how the sand can be so hot.
W: Well, professor Brock’s lecture on specific heat might give you a clue. Water has a higher specific heat than sand.
M: Then why is the sand so much hotter if water has a higher specific heat?
W: Don’t you remember? Specific heat is the energy needed to raise the temperature of something. If something has a high specific heat, like water, it takes more energy to raise its temperature.
M: I see. So you are saying that something with a high specific heat, like water, doesn’t get hot as fast as something with a low specific heat, like sand, right?
W: Right. So sand gets hot faster during the day, that’s why it’s so hot while the water’s still cool.
M: I guess you are right, I should pay more attention in class.
12 What do we know about Mark from the conversation?
13 What is the meaning of specific heat?
14 Why is the sand hotter than the water?
15 What can we infer from the conversation?
选项
A、He is curious.
B、He is warm-hearted.
C、He is impatient.
D、He is absent-minded.
答案
D
解析
男士说在水还冷的情况下,怎么沙子会那么热,女士问他是不是在Brock教授物理课讲解比热的讲座上睡着了,对话中间女士又说男士没留意他自己的问题,她给男十解释了比热原理并回答了男士一开始的疑惑,男士听明白后在对话最后说自己应该在课堂上多注意听讲。从对话中可知,男士是“心不在焉的”,应选D。
