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 10 to 15 percent 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.” Why does the writer say “laughter is mostly about social responses rather than reaction to a joke”?
| 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. |
From the last two paragraphs we know that______.
| 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 |
Which of the following statements is true according to the passage?
| 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. |
Wilderness
"In wilderness (荒野) is the preservation of the world." This is a famous saying from a writer regarded as one of the fathers of environmentalism. The frequency with which it is borrowed mirrors a heated debate on environmental protection: whether to place wilderness at the heart of what is to be preserved.
As John Sauven of Greenpeace UK points out, there is a strong appeal in images of the wild, the untouched; more than anything else, they speak of the nature that many people value most dearly. The urge to leave the subject of such images untouched is strong, and the danger exploitation (开发) brings to such landscapes (景观) is real. Some of these wildernesses also perform functions that humans need—the rainforests, for example, store carbon in vast quantities. To Mr. Sauven, these "ecosystem services" far outweigh the gains from exploitation.
Lee Lane, a visiting fellow at the Hudson Institute, takes the opposing view. He acknowledges that wildernesses do provide useful services, such as water conservation. But that is not, he argues, a reason to avoid all human presence, or indeed commercial and industrial exploitation. There are ever more people on the Earth, and they reasonably and rightfully want to have better lives, rather than merely struggle for survival. While the ways of using resources have improved, there is still a growing need for raw materials, and some wildernesses contain them in abundance. If they can be tapped without reducing the services those wildernesses provide, the argument goes, there is no further reason not to do so. Being untouched is not, in itself, a characteristic worth valuing above all others.
I look forward to seeing these views taken further, and to their being challenged by the other participants. One challenge that suggests itself to me is that both cases need to take on the question of spiritual value a little more directly. And there is a practical question as to whether wildernesses can be exploited without harm.
This is a topic that calls for not only free expression of feelings, but also the guidance of reason. What position wilderness should enjoy in the preservation of the world obviously deserves much more serious thinking. John Sauven holds that __________.
| A．many people value nature too much |
| B．exploitation of wildernesses is harmful |
| C．wildernesses provide humans with necessities |
| D．the urge to develop the ecosystem services is strong |
What is the main idea of Para.3?
| A．The exploitation is necessary for the poor people. |
| B．Wildernesses cannot guarantee better use of raw materials. |
| C．Useful services of wildernesses are not the reason for no exploitation. |
| D．All the characteristics concerning the exploitation should be treated equally. |
What is the author's attitude towards this debate?
| A．Objective. | B．Disapproving. | C．Sceptical. | D．Optimistic. |

C: Conclusion
A couple from Miami, Bill and Simone Butler, spent sixty-six days in a life-raft (救生艇) in the seas of Central America after their boat sank.
Twenty-one days after they left Panama in their boat, Simony, they met some whales (鲸鱼). "They started to hit the side of the boat," said Bill, "and then suddenly we heard water." Two minutes later, the boat was sinking. They jumped into the life-raft and watched the boat go under the water.
For twenty days they had tins of food, biscuits, and bottles of water. They also had a fishing-line and a machine to make salt water into drinking water—two things which saved their lives. They caught eight to ten fish a day and ate them raw (生的). Then the line broke. "So we had no more fish until something very strange happened. Some sharks (鲨鱼) came to feed, and the fish under the raft were afraid and came to the surface. I caught them with my hands. "
About twenty ships passed them, but no one saw them. After fifty days at sea their life-raft was beginning to break up. Then suddenly it was all over. A fishing boat saw them and picked them up. They couldn't stand up. So the captain carried them onto his boat and took them to Costa Rica. Their two months at sea was over. The whales hit the side of the boat, and then __________.

After giving a talk at a high school, I was asked to pay a visit to a special student. An illness had kept the boy home, but he had expressed an interest in meeting me, and it would mean a great deal to him. I agreed.
During the nine-mile drive to his home, I found out something about Matthew. He had muscular dystrophy (肌肉萎缩症). When he was born, the doctor told his parents that he would not live to five years old, then they were told again he would not live to ten. Now he was thirteen. He wanted to meet me because I was a gold-medal weight lifter, and I knew about overcoming obstacles and going for my dreams.
I spent over an hour talking to Matthew. Never once did he complain or ask "Why me?" He talked about winning and succeeding and going for his dreams. Obviously, he knew what he was talking about. He didn't mention that his classmates had made fun of him because he was different. He just talked about his hopes for the future, and how one day he wanted to lift weight with me.
When we finished talking, I went to my briefcase (公文包) and pulled out the first gold medal I won and put it around his neck, I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would. He looked at it for a moment, then took it off and handed it back to me. He said, "You are a champion. You earned that medal. Someday when I get to the Olympics and win my own medal, I will show it to you."
Last summer I received a letter from Matthew's parents telling me that Matthew had passed away. They wanted me to have a letter he had written to me a few days before: Dear Rick,
My mom said I should send you a thank-you letter for the picture you sent me. I also want to let you know that the doctors tell me that I don't have long to live anymore. But I still smile as much as I can.
I told you someday I was going to the Olympics and win a gold medal. But I know now I will never get to do that. But I know I'm a champion, and God knows that too. When I get to Heaven, God will give me my medal and when you get there, I will show it to you. Thank you for loving me.
Yours,

Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface.
A team from the Hokkaido Industrial Research Institute has built a number of "melody roads," which use cars as tuning forks (音叉) to play music as they travel.
The concept works by using grooves (凹槽). They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes.
Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune.
Paten documents for the design describe it as notches (刻痕) "formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody—like tones".
There are three musical strips in central and northern Japan—one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer (推土机) before driving over them and found that they helped to produce all kinds of tones.
The optimal speed for melody road is 44kph, but people say it is not always easy to get the intended sound.
"You need to keep the car windows closed to hear well," wrote one Japanese blogger. "Driving too fast will sound like playing fast forward, while driving around 12 mph [20km/h] has a slow-motion effect, making you almost car-sick." According to the passage, melody roads use __________ to create different notes.
| A．cars | B．grooves |
| C．spaces between intervals | D．bulldozers |
We can learn from the passage that the highness of notes is depended on __________.
| A．how far the grooves are | B．how big the grooves are |
| C．the number of the grooves | D．the speed of the car |
The underlined word "optimal" in the passage might mean __________.
| A．fastest | B．possible | C．best | D．suitable |
What's the best title of the passage?
| A．A New Type of Music | B．Melody Roads in Japan |
| C．A Musical Road Surface | D．A New Invention in Japan |
Daniel stays home on workdays. He starts his personal computer in order to connect with the office which is about three hundred miles away in another city. After work, he puts on his headphones, watches a movie on his home video recorder, or plays baseball on the computer. On many days, Daniel doesn't talk to any other human beings, and he doesn't see any people except the ones on television. Daniel is imaginary, but his lifestyle is very possible. The inventions of modern technology seem to be cutting us off from contact with our fellow human beings.
The world of business is one area in which technology is separating us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents, and accountants could do their jobs at display terminals (终端) in their own homes. They would never have to actually see the people they're dealing with. In addition, the way employees are paid will change. Workers' salaries will be automatically paid into their bank accounts, making paper checks unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take out money from their accounts. Many companies and consumers have already changed the way they sell or buy products. E-commerce, or business done on the Internet, is becoming more and more popular. This, therefore, makes it possible for people to do shopping without going out of their homes.
Another area that technology is changing is entertainment. Music, for example, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living-rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing as well. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living-rooms. After work, Daniel likes to __________.
| A．listen to music at the concert hall |
| B．watch a movie in his living-room |
| C．chat with his friends on the net |
| D．play baseball with his workmates |
The underlined sentence "Daniel is imaginary, but his lifestyle is very possible" means __________.
| A．Daniel is a person full of imagination and he can make his life colorful. |
| B．Daniel is not a real person but the lifestyle of his kind does exist. |
| C．Daniel is only an ordinary person but he has his own way of living. |
| D．Daniel is a model who makes full use of modern technology in life. |
What will the writer most probably discuss after the last paragraph?
| A．Games and sports | B．Personal banking |
| C．Music and films | D．International business |
What is the main idea of the passage?
| A．We may no longer need to communicate wit other human beings. |
| B．Modern technology seems to be separating human beings. |
| C．We may no longer need to work in the office. |
| D．Modern technology makes it possible for us to work and entertain ourselves at home. |
