It is difficult for doctors to help a person with a damaged brain Without enough blood, the brain lives for only three to five minutes More often the doctors can’t fix the damage Sometimes they are afraid to try something to help because it is dangerous to work on the brain The doctors might make the person worse if he operates on the brain
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple
This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.
Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler
RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.
1. The article is intended to______.
A. warn people of the possible risks in adopting RFID technology

A. will have no trouble getting data about others
B. will have more energy for conversation
C. will have more time to make friends
D. won’t feel shy at parties any longer
3. Passive RFID tags chiefly consist of .
A. scanning devices B. radio waves C. batteries D. chips
4. Why are some people worried about RFID technology?
A. Because children will be tracked by strangers.
B. Because market competition will become more fierce.
C. Because their private lives will be greatly affected.
D. Because customers will be forced to buy more products.
5. The last paragraph implies that RFID technology .
A. will not be used for such matters as buying milk
B. will be widely used, including for buying milk
C. will be limited to communication uses
D. will probably be used for pop music

Tragedy at the Circus
In yesterday’s circus（马戏团）show, a tiger suddenly attacked its trainer and had to be shot dead. As the circus packed up and left, circus officials said the show would go on, even without tigers.
However, the officials can’t simply turn a blind eye to the ethical problems left behind. Even before this tragedy(悲剧), animal rights activists protested against keeping wild animals in unnatural conditions and forcing them to suffer for the profit(利润) of circus organizers.
It is now time for us to take effective steps to make sure that circus animals are treated properly.
Circus Safe for Animals
Our circus recently suffered a most tragic event in its history. While we are thankful for the pity from the public, we are also astonished by the opinion expressed in “Tragedy at the Circus.”
First, our performing animals are not taken from the wild. As to the ethical problems. we always believe humans and animals can—and should—live together nicely. To us, the performing animals are representatives of their species(物种), and our circus is one of the only places left willing to support this special role of performing animals in the existence of the species. Those who argue that circus life is harmful to animals show little knowledge of these facts. Life in the “wild” is unsafe, but a continuous struggle for existence. To overlook these realities is the greatest fault against the animal kingdom.
This circus has proven that animals are stronger and smarter than we could imagine. Within the circus is a joyful atmosphere for both animals and humans: people are educated, and species saved.
1.What is the main purpose of the first passage?
A.To show pity for the performing animals.
B.To express worries about animal trainers' safety.
C.To deal with the difficult situations of the circus
D.To call for action to protect circus animals.
2.What will the circus most probably do?
A.Take no notice of the tragedy.
B.Continue its performances.
C.Use fewer wild animals.
D.Limit its profit.
3.What does the circus think of its performing animals?
A.They are as clever as human beings.
B.They struggle continuously with human beings for existence.
C.They are helpful in saving their species.
D.They have equally natural living conditions as wild animals.
4.What is the most probable relationship between the two passages?
A.A public request and a newspaper report.
B.A newspaper article and a reply to it.
C.Two parts of a newspaper article.
D.Two newspaper reports.

Lack of parent willpower may contribute more to juvenile obesity than under-exercising or overeating.
Research suggests that having overweight parents is a big, influence ( 影响) upon a child' s weight, with one study finding that child ren with overweight parents were four times more likely to be overweight themselves.
The findings add heat to an already fierce political debate（争论）over childhood obesity. The Prime Minister, John Howard, last week decided that $116 million be Used for programs to deal with obesity, while the Opposition Leader, Mark Latham, recently announced that his party would move to protect children from unhealthy food advertisements
Clare Collins a senior lecturer at the University of Newcastle, believes such programs will definitely fail unless they influence the way of life of whole families. "If we can' t get parents to take action against their own weight problems, then we can' t expect to influence their kids," she said.
However, Professor, Louise Baur from the Children’ s Hospital at Westmead, doubts whether adult education programs offer any solution to weight problems. "Many parents know they need to lose weight and they know it influences their kids, but they lack the willpower to do anything about it.
The 10-year study of 150 American children found two-thirds of children with overweight parents became overweight. Only one in six children whose parents were of average weight became overweight.
The president of the Australasian Society for the .Study of Obesity, Associate Professor Gary Wittert, said parents needed help in doing their job and the Opposition Party’s policy（政策） might be on the right track.
"We know that driving without a seat belt is unsafe, so we make law against it,” he said."Obesity is a major public health concern, so why shouldn’t we change the law regarding unhealthy food ads?"
1. What does the underlined phrase “juvenile obesity” mean?
A. Adult education. B. Childhood overweight
C. Parents’ influence D. Growing pains
2. What is TRUE about the programs supported by the Prime Minister?
A. Debates on them will become less fierce.
B. They will be effective in dealing with obesity.
C. A large sum of money will be spent on them.
D. They will influence people' s way of life.
3.Both Collins and Baur believe that overweight parents_______,
A. will come up with .better solutions
B. will help with their children' s education
C. should be more active in reducing weight
D. should carry out at least 10 years' study
4. According to some experts, the Opposition Party's policy________.
A. can help fight against unemployment
B. may protect kids from unhealthy food ads
C. should be brought back to the right track
D. will work well to prevent traffic accidents
