If you need glasses to read this, you are among most of Chinese students. About four-fifths of high school students in China have poor eyesight(视力). And now more and more children in primary school need glasses, too.

Two main reasons can cause poor eyesight: too much time spent indoors studying and too little time spent outdoors playing. Reading and writing for hours and hours, sometimes in poorly lighted rooms, causes eyesight to weaken. But students have to do this because there is so much pressure on them to succeed in school. They have less time to enjoy the sun.

The sun, it turns out, is important in developing good eyesight. According to a study by Australian National University, Australian children and Chinese children have the same level of eyesight before they start school, but once they enter primary school, Chinese children only spend about an hour a day outside, while Australian children spend three to four hours each day in the sunshine. The result is that while about forty percent of Chinese primary school students need glasses, only three percent of Australian children do.

And poor eyesight at a young age can have serious long term influence. As you get older, your eyesight can worsen.

With all that in mind, don’t you think it’s time to give your eyes a break?

1.How many high school students have poor eyesight in China according to the reading?

Although most people believe 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 above all else is a social thing,” says Baltimore neuroscientist(神经科学家), Robert Provine, who has studied laughter for many years. “All laughter groups 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 our first way of communicating. Babies laugh long before they speak. No one teaches them how to laugh. They just do. People may laugh at a prank(恶作剧) on April Fools’ Day. But surprisingly, only 10 to 15 percent of laughter is the result of someone making a joke. Laughter is mostly about social responses rather to a joke. Deaf people laugh without hearing and people on cell phones laugh without seeing, showing that laughter isn’t dependent on single sense but on social interactions.

And laughter is not just a people thing. Chimps tickle(挠痒) each other and even laugh when another chimp pretends to tickle them.

Jaak Panksepp, a Bowling Green University Psychology professor, 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.

By studying rats, scientists can figure out what’s going on in the brain during laughter. Northwestern University biomedical engineering professor, Jeffrey Burgdorf has found that laughter in rats produces a chemical that acts as an antidepressant(抗抑郁药). He thinks the same thing probably happens in humans, too. This would give doctors a new chemical target to develop drugs that can fight depression.

Even so, laughter itself has not been proved to be the best medicine, experts said. Margaret Stuber, a professor at University of California, studied whether laugher helped patients. She found that distraction(分心) and mood improvement helped, but she could not find a benefit of laughter alone.

“No study has shown that laughter produces a direct health benefit,” Provine said, mainly because it’s hard to separate laughter from just feeling good. But he thinks it doesn’t really matter: “Isn’t the fact that laughter feels good when you do it enough?”

1.The underlined word “figure out” in Paragraph 6 means “________”.

A. deal with B. work out

C. look out of D. come up with

2.According to the passage, scientists studied rats in order to find ______.

A. how they laugh

B. if they like laughing

3.What can we know from Robert Provine’s research?

A.Laughter makes a person feel good.

B.Laughter produces a direct health benefit.

C.Laughter depends on all kinds of senses.

D.Laughter is a way of communicating.

4.What is probably the best title for this passage?

A. Why Rats Laugh

B. When Laughter Happens

C. How Laughter Works

D. Why Laughter Matters
