A new computer treatment is being used to deal with obesity in children. Connected to a small dining set, consisting of (包括) scales and a plate, a mini computer teaches children how to eat and reminds them when to stop.
“In very fat people, hunger signals from the stomach to the brain stop functioning. But the new computer system teaches the children how to receive these messages again,” says Dr. Julian Hamilton-Shield, the Bristol University senior lecturer leading the treatment trials.(实验)。
The computer , called a Mandometer, records and stores the weight loss from the plate when children eat. As the food is leaving the plate , a curve( 曲线)is produced on the computer screen suggesting whether the child is eating too quickly.
“Children with weight problems often eat too quickly. We want them to eat steadily稳定地） and slowly and the system teaches them to slow down. It’s a bit like retraining, ” says Hamilton-Shield.
Obesity now represents (代表) one of the major threats to the future health of children. About one in five boys and one in four girls aged two to fifteen in England are overweight. But so far no treatments have proven effective in treating children.
The Mandometer was developed in Sweden, but at present is experiencing further development at the University of Bristol, with $ 224,400 in funds from BUPA-a global health and care organization. The system could be on the market in two years’ time. At first, it would be managed by medical clinics(诊所).

When my mother was alive, she used to tell me again and again about the value of just being nice. “Never underestimate（低估）the power of a smile,” she would say. I fear she would be very disappointed looking at the world today. A lot of people don’t smile and when it comes to service today, they’re just not nice. Now don’t give me wrong, not all service workers but a good many.
I was on the phone the other day with a computer help desk. First a man, then later a woman, who couldn’t have been ruder. And this to a customer, who didn’t know his way around a PC. But no matter, I could tell they thought I was a bother, The woman, in fact, seemed to be chewing gum as she unemotionally clicked off a series of commands for me to perform.
The next day I heard from a friend of mine who got a performance review without his boss once looking up at him. Not once.
You see it everywhere. Gone are the days when people cared about you. It’s a sign of the time, I suspect. But that makes me sad — for them and for us all. People who aren’t happy, who don’t smile, who don’t kid, who don’t joke or make light of even bad situations, make for an even worse situation.
And it spreads like a cancer. Someone’s rude to you, you’re rude to them and to the next fellow you meet, and on and on. Smiles are contagious（易感染的）but so annoyances. The boss who can’t be bothered with his workers. The celebrity who can’t be bothered with her annoying fans.
You know, my mom used to judge presidential candidates by how they smiled. I would say, “But mom, you don’t know if that smile is real.”
“Oh, yes I do,” she would tell me. “I can feel it.”
It’s in their eyes, she would say. And it’s in their smile. The rest just kind of falls into place.Why did the writer mention his phone call?

As temperatures go up, bison（北美野牛）get smaller. Joseph Craine, research assistant professor in the Division of Biology at Kansas State University, examined how climate change during the next 50 years will affect grazing（放牧）animals such as bison and cattle in the Great Plains.
“Bison are one of our most important conservation animals and hold a unique role in grasslands in North America,” Craine said. “In addition to their cultural and ecological significance, they’re economically important. There are about half a million bison in the world.” Craine analyzed a data set of 290,000 weights, ages and sexes collected from 22 bison herds（兽群）throughout the U. S. The organizations kept annual records of each animal in the herd and matched the data with the climates of the sites.
Based on differences in sizes of bison across herds, Craine found that during the next 50 years, future generations of bison will be smaller in size and weigh less. Climate is likely to reduce the nutritional quality of grasses, causing the animals to grow more slowly.
“We know that temperatures are going to go up,” Craine said. “We also know that warmer grasslands have grasses with less protein（蛋白质）, and we now know that warmer grasslands have smaller grazers. It all lines up to suggest that climate change will cause grasses to have less protein and cause grazers to gain less weight in the future.”
Craine said the results of climate change in coming decades can already be seen by comparing bison in cooler, wetter places with those in warmer, drier places. For example, the average 7-year-old male bison in South Dakota weighed 1, 900 pounds, while an average 7- year-old male bison in Oklahoma — a warmer place — weighed 1, 300 pounds.
“The difference in temperature between those two states is around 20 degrees Fahrenheit, which is about three times the projected increase in temperatures over the next 75 years,” Craine said. “It is a clear indicator that long-term warming will affect bison and is something that will happen across the U.S. over the next 50-75 years.”In the next fifty years, researchers Say, bison will ________.
| A．become smaller and lighter |
| B．disappear in the Great Plains |
| C．play a less important part |

What is the main reason for the bison to become smaller?
| A．The deceasing amount of grass. |
| B．The rising temperature. |
| C．The rising number of bison. |
| D．The loss of weight. |

| B．bison are smaller than in the past |
| C．the nature balance is being destroyed |

Speaking from my past experience, it is very difficult to find good friends that you can trust but once you have found them, they are worth keeping forever! Therefore, I think friendship is the most important relationship that anybody could have.
The qualities I look for in a friend are a good sense of humor but sensitivity when it matters. Also that friend would have to be strong-minded and highly spirited. I think that these qualities are the key qualities to look for in a good friend.
Even the strongest friends can still have arguments, although usually about more serious topics, rather than the usual teenage childish arguments. Some matters can seriously affect a friendship. If one of your friends started experimenting with harmful and dangerous drugs, what would you do ? A good friend would try to help as much as possible, whereas a bad example of a friend would simply shrug(耸肩) and turn a blind eye.
Not only the bad things affect friendship ---- good activities do too. Such as bonding with one another, not just by going out on a night with them but by spending quality time with them and talking to each other, which indicates a good ability to communicate. This is a key aspect of a good friendship.
Good friends do not always have to be in the same age group as you. I have a good friend and she is 47 years old and I am 16.
Unfortunately, some people lose contact with their friends as they grow older, which is a sad way to lose a good friend.
I think friendship is one of the most important things in life because if you have no friends you will have no happiness.
| A．is easy to get | B．deepens with time |
| C．needs management | D．affects one’s happiness |
| A．why drugs are bad for teenagers |
| B．problems that will test friendship |
| C．ways that help avoid arguments |
| D．whether a friend is trustworthy |
| A．Age. | B．Sensitivity. |
| C．Sense of humor. | D．Communication ability. |
| A．Old friends and old wines are best. |
| B．A friend without faults will never be found. |
| C．A life without a friend is a life without the sun. |
| D．a friend to everybody is a friend to nobody. |
A new generation addiction is quickly spreading all over the world. Weboholism（网瘾）, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.
Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. Such behavior has seriously affected teenagers and college students. They are likely to log(写日志) on computers and spend long hours at different websites.
They become hooked（着迷） on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.
They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.
Because of the change in their behavior, they begin to isolate themselves from society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect all the world.
