B
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 (腦震蕩) 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 (外傷的) 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.
【小題1】The passage is most probably a ________.

A.news report B.research report
C.story for soccer players D.text for doctors
【小題2】 In which way can researchers find the structural changes in the brain?
A.Computerized test B.Questionnaire
C.Scanning D.M.R.I. technique
【小題3】 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
【小題4】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
【小題5】The underlined word “fumbling” is closest in meaning to ________?
A.remembering B.misunderstandingC.recalling D.missing

A mum saved her daughter’s life with her newly learned first aid skills. Sonya Hall, 33, of Denny Avenue, Lancaster, had only just attended one first aid class the day before when she found herself needing to use the skills on her three year old daughter Tilly.
Sonya, who also has son Emmen, six, attended the first aid course at Lune Park Children’s Centre in Lancaster. Then she was faced with every parent’s worst nightmare when Tilly went blue in the face and stopped breathing. But thanks to her newly acquired skills, Sonya saved Tilly’s life.
Sonya said: “Tilly was playing with her brother and they were fighting over a toy. Emmen won the fight. Tilly fell backwards and her head was hit. She was face down and shaking and at first I thought she was upset. But then I saw she was blue in the face and had stopped breathing. I reacted without thinking and immediately started using the first aid skills I had learned the day before which were so fresh in my mind. I began doing mouth-to-mouth and chest compressions (胸外按壓). It probably took about a minute before Tilly started breathing again, but to me it felt like a lifetime.”
After getting Tilly breathing again, Sonya called an ambulance and the doctors came. Since then, Tilly has been diagnosed (診斷) with Reflex Anoxic Seizure (反射缺氧發(fā)作). Sonya said: “The seizure can happen when there’s any unexpected pain, fear or fright. It is just so lucky that the day before it happened, I had been practising first aid.”
The Empowering Parents First Aid course is run by Lancashire Adult Learning. Sonya said: “I am just so glad I did the course and learnt the first aid skills. I always feared I would not know what to do in a crisis situation, but luckily I had the knowledge and skills to deal with it.”

A little under one-third of U.S. families have no Internet access and do not plan to get it, with most of the holdouts seeing little use for it in their lives, according to a survey released on Friday.

Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe(預(yù)訂) to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost.

Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer "I'm not sure how to use the Internet" came from 17 percent of participants who do not subscribe. The response "I do all my e-commerce shopping and YouTube-watching at work" was cited by 14 percent of Internet-access refuseniks. Three percent said the Internet doesn't reach their homes.

The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted(轉(zhuǎn)變) from slower-speed, dial-up Internet access while the other half of families had no prior access.

"The industry continues to chip (擊破)away at the core of non-subscribers, but has a long way to go," said John Barrett, director of research at Parks Associates. "Entertainment applications will be the key. If anything will pull in the holdouts, it's going to be applications that make the Internet more similar to pay-TV," he predicted.

What does the underlined word “holdouts” in the first paragraph most probably mean?

A. some American families      

B. those who hold out one’s opinions

C. those who have been surveyed    

D. those who still haven’t access to the Internet currently

Many potential customers refuse to subscribe to the Internet mainly because __________.

A. they show too much concern about the cost

B. they can find little value of it

C. they do most YouTube-watching at work

D. the Internet doesn’t reach their homes

From the passage we can infer that _____________.

A. It is not an easy job to transform those holdouts into the Internet users

B. people will adopt dial-up Internet access no more

C. many Americans enjoy doing e-commerce shopping at home

D. more than half of the population are using the Internet in 2005

According to John Barrett, what is the key to attracting more U.S. families to broadband service?

A. making the Internet look more similar to TV set

B. applying the Internet more to entertainment

C. providing more pay-TV programs

D. chipping away at the core of non-subscribers

Which is the best title for the passage?

A. Web develops with technology

B. The present situation of web

C. Many Americans see little point to web

D. It is urgent to promote web service

How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the U.S.

For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as dangers and with good guides, some education, and a few precautions(預(yù)防措施), the wilds of the Internet can be safely navigated(航行). “Kids have to be on-line. If we tell our kids they can’t have access(機(jī)會(huì)) to the Internet, we’re cutting them off from their future,” said an expert.

Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way to limit access would be to use what is known as a “content screener(過濾器)”. But this can’t be wholly reliable(可靠), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing(瀏覽) the Internet.

A few other tips

●Don’t put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.

●Ask your child what he or she has been doing and about any friends they make on-line.

●Tell your child not to give on-line strangers personal information, especially like address and phone number.

●And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

The passage is mainly about the subject of _______.

A. American children going on-line             B. Internet in America

C. appreciating Internet                              D. opposing children’s on-line

The best way to protect children from improper material is _______.

A. to install(安裝) a content screener on the computer

B. to buy some search engines for the children

C. to be nearby when they are surfing the Internet

D. to talk to the children and persuade them to tell right from wrong

Which of the following is right according to the passage?

A. Surfing the Internet is the best method of educating children.

B. Children’s not having access to Internet may have effect on their progress.

C. Using a content screener is most reliable for keeping children having access to Internet.

D. Searching engines can help children to select materials fit for them.

According to the passage, we can infer that _______.

A. soft wares fit for children want programming

B. a child who is on-line is in danger

C. Internet is a jungle full of danger

D. Internet contains a lot of harmful sites
