What happens inside the skull of a soccer player when repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can’t be seen during most scans.
According to the data they presented at Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is “similar to those seen in traumatic (外伤的) brain injury”, like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less. The passage is most probably a ________.
| A．news report | B．research report |
| C．story for soccer players | D．text for doctors |
In which way can researchers find the structural changes in the brain?
| A．Computerized test | B．Questionnaire |
| C．Scanning | D．M.R.I. technique |
From the passage we can conclude that frequent heading may have ________.
| A．significant effect on brain | B．little effect on one’s brain |
| C．nothing to do with the brain injury | D．one’s memory improved |
What is likely to be the cause of memory loss?
| A．Playing soccer frequently | B．Tests of their memory |
| C．White matter loss | D．Information processing |
The underlined word “fumbling” is closest in meaning to ________?
| A．remembering | B．misunderstanding | C．recalling | D．missing |

I’m a 20-year-old boy, and the following is my story．
A month after I graduated from high school in August，2007，I was coming home from swim practice in the training centre of the city and was involved in a car accident. I was so seriously injured that I was in a coma for more than two months at Prince Georges Hospital．
I suffered a lot from the experience of dying eight times during my coma and I couldn’t open my mouth to talk or to communicate when I eventually came around．At that time，it seemed that walking was never going to happen again due to all the extreme injuries. Just like my body，my dreams were completely destroyed. But I was not going to let my injuries stop me from realizing my dreams．
After receiving a total of 15 operations and 36 blood transfusions, I had to make every great effort to learn to talk，eat，walk，shower，and live on my own again．When I was out of hospital，I still had to go to outpatient therapy in Waldorf, Maryland．After I spent a few months in a wheelchair, I took baby steps to walk on my own．It was a miracle that I was able to walk again, but I still wanted to prove that I could not only walk, but also run. When it came true, I wanted to get back into the pool again．After having a few lung tests，I was able to go in the pool a little bit each week．After a few months of swim training，I began my freshman year at Mary’s College of Maryland and then became a proud member of the swim team．
By telling my story, I want to make a positive influence on the world．I am just trying to 1ive every day to the fullest and inspire other people never to give up their dreams no matter how bad a situation is to them. I remember when I was still in my hospital bed，I would have my mom and dad push me round in my wheelchair to the other rooms to see the other patients and chat with them and their family members．I wanted to let them know that everything was going to be okay. Somehow，things would work out for the best.The underlined word “coma” in Paragraph 2 probably has the meaning of __________.

Even if you are an experienced backpacker or climber，you need to know what to do if something goes wrong．It is not that Alaska is that much more dangerous than other places．It is no more hazardous than elsewhere，as long as the proper precautions(预防措施)are taken．So, being prepared is crucial to ensure a safe trip．
First of all，make sure you pack everything you will need for your trip．Even if you are traveling by car，pack clothes and gear for backpacking．Because of the bad weather, cars break down frequently. Pack a survival(生存)kit full with：a down coat, boots ,mittens, a hat, snow-pants，sleeping bags，candles，a flashlight，and high-energy food. If you are traveling by car , also pack extra belts, a shovel, and a chain.
If you are camping or hiking，make sure you know how to avoid bears．If you are lost in the wilderness, there is no doubt you will encounter them.
However，there is no need to be nervous．Just take these precautions：make noise as you walk，bears will avoid you；cook your food away from where you sleep，and store your food away from where you sleep，so the bears are not attracted．Both of these should keep the bear away．However，if you do encounter a bear，there are two different schools of thought．One is to make noise and scare the bear away．The other is to stand still and speak softly to get the bear to leave．If you are dealing with a brown bear，you can climb a tree，since it cannot follow．But，black bears can climb．If for some reason the bear attacks，play dead．Try to protect your head and neck，and hopefully the bear will leave its“dead” prey.The underlined word “hazardous” in Paragraph l most probably means________．

How often do you change your hairstyle or ask for new dresses? You may try to follow trends in Western countries，but your peers(同龄人)in the United States don't care as much about fashion(时尚)as you do．
A recent survey among high school students in China，Japan，South Korea and the US found that Asian teenagers care more about their looks than young people in the US．
This survey was held in 156 high schools in the four countries. More than 7,000 teenagers were questioned about their view on life and the world.
South Koreans, at 83 percent, cared most about their appearance. They were followed by the Chinese and Japanese while US students showed the least interest in fashion at only 33 percent.
“The different results show differences of cultural background,” said Sun Yunxiao from the China Youth and Children Research Centre.
He explained that in the US there are many different standards of beauty, so teens are more likely to be confident about their appearance.
US teenagers’ high self-confidence is showed in survey. About 85 percent are happy with themselves. The percentage of self-confident Chinese students stands at only 30 percent.
Strong ambition( 雄心) is seen in Chinese high schools. Only two in five high school students are satisfied with “an average living”. Koreans are next at 48 percent，Japanese come in at 66 percent and Americans are at 71．

Many famous museums throughout the world can offer you good chances to admire art. Washington, D.C has the National Gallery of Art，Paris has the Louver, London, the British Museum. Florida International University(FIU) in Miami also shows art for people to see. And it does so without a building, or even a wall for its drawings and paintings.
FIU has opened what it says is the first computer art museum in the United States. You don’t have to visit the University to see the art. What you need is just a computer linked to a telephone. That’s enough.
You can call the telephone number of a University computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings.
Robert Shostak is director of the new computer museum. He says he started the museum because computer artists had no place to show their work.
A computer artist could only record his pictures electronically and send the records, or floppy discs, to others to see on their computers. He could also put his pictures on paper. But to print good pictures on paper, the computer artist will have to need a very expensive laser printer.
Robert Shostak says the electronic museum is mostly for art or computer students at schools and universities. Many of the pictures in the museum are made by students. Mr Shostak said the FIU museum will make computer art more fun for computer artists because more people can see it. He says artists enjoy their work much more if they have an audience. And the great number of home computers in America could mean a huge audience for the electronic museum.The main purpose of this text is to give information about____________.
