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
C. what laughter in rats produces
D. how rats react while being tickled
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

DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”（基因）in our body. In 1953, two scientists, Watson and Crick, found out that genes are really messages. They’re written in the DNA with a special language.
In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell (细胞）to build its parts. So far, scientists have found all the words in the DNA map, but we still don’t understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way. Just to make people more attractive (有吸引力的), or stop sick people getting jobs.
1.When did Mr. Mendel discover why we look the same as other people in our family?
