Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient - no matter where he or she may be.

  Online doctors offering advice based on norman symptoms(症状)are the most obvious example. Increasingly, however, remote diagnosis(远程诊断)will be based on real physiological data(生理数据)from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone ,it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipement, the cry asking whether there was a doctor in the house could well be a thing of the past.

  Other medical technology groups are working on applying telemedicine to rural (countryside) care. And at least one team wants to use telemedicine as a tool for disaster need - especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.

  But there is one problem. Bandwidth(宽带) is the limiting factor for sending complex (复 杂 )medical pictures around the world,—CU photos being one of the biggest bandwidth users. Communication satellites say be able to deal with the short - term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second - generation Internet and third generation mobile phones for the future of remote medical service.

  Doctors have met to discuss computer - based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’opinions and diagnosis are common.

  The writer chiefly talks about ________ .

  A. the use of telemedicine

  B. the on -lined doctors

  C. medical care and treatment

  D. communication improvement

  Which of the following statements is true according to the text?

  A. Patients don’t need doctors in hospitals any more.

  B. It is impossible to send a patient’s signs over the telephone.

  C. Many teams use telemedicine dealing with disasters now.

  D. Broadband communications will become cheaper in the future.

  The“problem”in the fourth paragraph refers to the fact that ________ .

  A. bandwidth isn’t big enough to send complex medical pictures

  B. the second - generation of Internet has not become popular yet

  C. communication satellites can only deal with short - term needs

  D. there is not enough equipment for spreading the medical care 

The scientists observed that the more junk food the rats ate, the more they wanted to eat – a behavior very similar to that of rats addicted(上了瘾的) to heroin, a dangerous drug. Johnson said the experiment shows that the brain chemistry of obesity(肥胖) and drug addiction may be quite similar.

In their experiment, Johnson and his team studied the “pleasure center” of rats’ brains. The pleasure center is a complicated network of nerve cells. If the animal exercises or eats, the cells reward the animal by releasing chemicals into the body that make it feel good. And when the body feels good, the animal – or person – will want to do the behavior again.

For the experiment, Johnson fed foods like cheesecake to one group of rats. Food like this is high in calories and fat. Another group of rats got a regular diet. The rats that ate junk food started to eat more and more.

“They’re taking in twice the amount of calories as the control rats,” says Paul Kenny, one of Johnson’s colleagues.

Kenny and Johnson wanted to know what was going on in the brains of these rats. They first designed a way to deliver a small electrical charge to the rats’ brains. This electrical charge would stimulate the pleasure centers to release pleasure-causing chemicals. The rats could control how much stimulation – and how much pleasure – they received by running on a wheel. The more the rat ran, the more pleasure it received.

The rats that had been eating junk food started running more and more. This behavior suggested that the junk-food-eating rats needed more brain stimulation to feel good compared with rats on a normal diet. In other words, their pleasure centers were becoming less sensitive and the junk food didn’t make them feel good unless they ate more and more.

Experiments like this one could help scientists understand how chemicals in the brain contribute to obesity. With that information, they may be able to help people avoid obesity in the first place.

In the computer age, most of us take a broadband(宽带)Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.

There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.

Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.

But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.

Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纤电缆) promise to bring extremely fast Internet connections to more users.

Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (迹象), it may not be too long before an Internet connection simply follows you wherever you go.

1.The underlined part “a catch” (in Paragraph 2) probably means “_____”.

A.a rare challenge    B.a desirable plan     C.an efficient device   D.a hidden problem

2.What can we know from the third paragraph?

A.Internet connection has not been popular in most cities.

B.Internet service providers care about rural(农村的)customers.

C.Computer is popular in developing countries.

D.It is hard to bring Internet access to users in remote areas.

3.Paragraph 4 mainly tells us that technological advancements _____.

A.make TV and telephone available everywhere

B.bring great change to people’s everyday life

C.make it possible for more people to use the Internet

D.bring faster Internet connections to users

4.What may eventually settle the “last mile” problem?

A.The broadband connection’s getting faster.

B.More and more Internet users.

C.more and more Internet connections.

D.The rapid progress in cell phone technology.

 

Greg Woodburn, a student at the University of Southern California, spends a lot of time cleaning sneakers he collected.But soon the shoes will be sent to poor children in the United States and 20 other countries, thanks to Woodburn’s Share Our Soles (S.O.S.) charity.

A high school track star in the town of Ventura, California, Woodburn was treated in hospital for months with knee and hip injuries.

“I started thinking about the health benefits, the friendship and the confidence I got from running,” he says, “And I realized there are children who don’t even have shoes.”

Woodburn gathered up his old sneakers, then asked his friends to donate.His goal was to have 100 pairs by Christmas this year.When he collected more than 500 pairs, he decided to turn the shoe drive into a year-round endeavor.

Back then, the sneakers came from donation boxes at the YMCA and the local sporting goods store and from door-to-door pickups.Woodburn has now set up collection boxes at two high schools, city gym and recreation center.He has started accepting adult sizes and sandals.So far, S.O.S has collected and donated more than 3,000 pairs.

Woodburn has cleaned all the shoes.After sorting the shoes by size, Woodburn selects the good shoes for the washing machine and the worn-out ones for recycling.

To ship the footwear, Woodburn teamed with Sports Gift, a nonprofit organization that provides soccer and baseball equipment to children around the world.Keven Baxter, founder and president, says, “We’d send kids balls and shoes.I've heard that for many of these kids, these old sneakers are the only shoes they had.They wear them to school and to do sports.So Greg’s running shoes were a nice addition for us.”

For many recipients, the shoes represent opportunity.Two young boys in Southern California attended school on alternate days because they shared a pair of shoes.They were too big for one boy and too small for the other.Thanks to S.O.S., each brother received his own pair of shoes.The boys now attend school daily and enjoy their learning.When they graduate, they say, they will help a stranger, just as Woodburn helped them.

1.What caused Greg Woodburn to donate old shoes for poor children?

A.The benefits from playing sports.

B.News about some poor children.

C.His reflection to school life.

D.The medical treatment he received.

2.When collecting more sneakers than expected, Woodburn decided to          .

A.include adult sizes and sandals

B.set up branches in different cities

C.collect shoes throughout the year

D.expand his endeavor in the whole city

3.How did Woodburn manage to deliver the shoes collected?

A.By sending them by mail.

B.By working with Sports Gift.

C.By advertising for those in need.

D.By offering them from door to door.

4.What can we learn from Keven Baxter’s remarks?

A.Sports Gift is popular around the world.

B.Many children need Greg’s old sneakers.

C.Greg’s running shoes are the best gifts for children.

D.International organization should provide more help.
