1.While most people consider that laughter is one of the nature's great treatments for a whole range of mental and physical diseases,it is still a serious scientific subject that researchers are trying to figure out."Laughter is social."says Robert R.Provine,author of the book"Laughter:A Scientific Investigation",who has been studying laughter for decades."Almost all people laugh‘ha-ha-ha'basically the same way.Whether you speak Mandarin,French or English,everyone will understand laughter.There is a pattern generator(发生器) in our brain that produces this sound.
Laughing is also a good way of communicating.Babies laugh long before they speak.No one teaches them how to laugh.They just do it.People may laugh at a prank(恶作剧) on April Fools'day.But surprisingly,only 10to 15percent of laughter is the result of someone making a joke.Laughter is mostly about social responses rather than reaction to a joke.Deaf people laugh without hearing and people on cell phones laugh without seeing,which shows that laughter isn't dependent on a single sense but on social interactions.
And laughter is not just a human thing.Chimps tickle(挠痒) each other and even laugh when another chimp pretends to tickle them.
Jaak Panksepp studies rats that laugh when he tickles them.It turns out rats love to be tickled.They return again and again to the hands of researchers tickling them,Panksepp's video shows.
By studying rats,scientists can figure out what's going on in the brain during laughter.It has been found that laughter in rats produces a chemical that acts as an antidepressant(抗抑郁药) and anxiety-reducer.Scientists think the same thing probably happens in humans,too.This would give doctors a new chemical target in the brain in their effort to develop drugs that fight depression and anxiety in people.
Even so,laughter itself has not been proved to be the best medicine,experts said."No study has shown that laughter produces a direct health benefit,"Provine said,"largely because it's hard to separate laughter from just feeling good."
64.Why does the writer say"laughter is mostly about social responses rather than reaction to a joke"?A
A.because people can communicate with each other by laughing.
B.because laughter is the same sound in all the human's languages.
C.because laughter is considered a basic language all people can learn.
D.because everyone can understand the meaning of the word laughter.
65.From the last two paragraphs we know thatC.
A.laughter has no direct connection with good feelings
B.laughing every day can cure people of many diseases
C.the medical functions of laughter are still under experiment
D.scientists have learned what is happening in a human brain when he laughs
66.Which of the following statements is true according to the passage?B
A.Laughter depends on many senses.
B.Laughter is a social response shared by all creatures.
C.If you speak different languages,you will laugh differently.
D.A new medicine has been developed based on the laughter research.
分析 本文是一篇科教类阅读,文章主要介绍了一项对笑的新研究,和以往人们的观点不同的是,研究人员发现笑是人类社会化的反应,而且动物也有相同的情况.所有人都知道微笑对我们的身体及精神都有很大的帮助作用,但事实上我们并不清楚对我们有好处的原因.笑从本质上来说是社会性的东西,不只是在人类中才有,动物中也有.因此,科学家研究老鼠是为了看在老鼠笑时会产生什么,通过研究发现大笑时会产生一种化学物质,其作用相当于抗抑郁药.
解答 64-66.ACB
64.A理解判断题.根据第三段Laughing is also a good way of communicating.和which shows that laughter isn't dependent on a single sense but on social interactions.可知笑是一种很好的交流方式,笑不依赖于单一感测,而是社会上的相互作用.由此可知,作者说"大笑"主要是社会反应,而不是对玩笑的反应,这是因为人们总是可以笑着互相交流.故选A.
65.C细节理解题.根据最后一段Even so,laughter itself has not been proved to be the best medicine,可知"笑"还没有被证明是一种很好的药.即笑声的医疗功能仍在实验.故选C.
66.B理解判断题.根据第四段And laughter is not just a human thing.Chimps tickle(挠痒) each other and even laugh when another chimp pretends to tickle them.可知笑不仅仅是人类的反应,猩猩互相挠痒也会笑.此外老鼠也会笑.由此可知,笑是一种所有的生物都有的社交反应.故选B.
