Tears keep your eyes wet and they also contain substance that kills certain bacteria so it can’t infect your eyes. Give up your tears and you lose this on-the-spot defense. Another thing you couldn’t do without your tears is cry from joy, anger or sadness. Humans are the only animals that produce tears hi response to emotions. And most people say a good cry makes them feel better. That has led many scientists to believe that crying is an adaptive response to stress, that it somehow helps us cope with emotional situations. Tear researcher William Frey is trying to find out how it happens.
    "One possibility," be 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 are doing." He says. If Frey is right, how do you think not crying affects those who tend to "hold it in"? 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.

选项 A、To keep your eyes a bit drier.
B、To protect your eyes from infection,
C、To cry for your sadness only.
D、To conceal your happiness.

答案 B

解析 综合推断题。由选项中的不定式推测本题是就一种现象或活动的目的或作用提问。抓住句子“Tears keep your eyes...can’t infect your eyes. ”及句子“Another thing you can’t do without...joy,anger,or sadness”可知眼泪不但可以保护眼睛,而且可以帮助表达人们内心的情感,如快乐、愤怒、悲伤等。最具干扰性的C、D两项太片面,可排除。所以,选项B正确。
