Why do we cry? Can you imagine life without tears?
    Not only do tears keep your eyes lubricated, they also contain a substance that kills certain bacteria so they can’t infect your eyes. Give up your tears and you lose this on-the-spot defence. Nor would you want to give up the flood of extra tears you produce when you get something physical or chemical in your eyes. Tears are very good at washing this irritating stuff out. Another thing you couldn’t do without your tears is cry—from joy, anger, or sadness.
     (23)Humans are the only animals that produce tears in response to emotions. And most people say a good cry makes them feel better.
     (24)Many scientists, therefore, believe that crying somehow helps us cope with emotional situations. Tear researcher William Frey is trying to figure out how it happens.
    One possibility, he says, is that tears discharge certain chemicals from your body, chemicals that build up during stress. "When people talk about ’crying it out,’ I think that might actually be what they arc doing," he says.
    If Frey is right, what do you think will happen to people who restrain their tears?(25)Boys, for example, cry only about a quarter as often as girls once they reach their teenage years. And we all cry a lot less now than we did as babies.
    Could it possibly be that we face less stress? Maybe we’ve found other ways to deal with it. Or maybe we just feel embarrassed.
Questions 23 to 25 are based on the passage you have just heard.
23. What’s the difference between human beings and other animals when shedding tears?
24. What is William Frey trying to find?
25. What does the passage say about teenage boys and girls?

选项 A、Why do humans cry.
B、What the emotional situations are when human cry.
C、What substance is contained in human’s tears.
D、How crying helps us deal with emotional problems.

答案 D

解析 细节题。要解此题,需要明确提到William Frey那句话中的it指代什么,从上文可知,it指“哭是如何帮助人类解决情感问题的”,后文提到的一种解释也可以给予提示,故选D。本题说明在做听力时,文中出现任何人名或人物时也需准确记录。
