A study published Monday found that people who sleep less tend to be fat, and experts said it’s time to find out if more sleep will fight fatness.
“We’ve put so much emphasis on diet and exercise that we've failed to recognize the value of good sleep,” said Fred Turek, a physician at Northwestern University.
Monday’s study from Eastern Virginia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index - a measure of weight based on height - increased.
Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights, it said. In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.
“Americans experience insufficient sleep and fat bodies. Clinicians are aware of the burden of fatness on patients,” the study said.
“Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index,” it added.
“We caution that this study does not establish a cause-and-effect relationship between restricted sleep and fatness (but) investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”
The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.
In an interview, Turek said some studies have shown sleep causes declines in an appetite suppressing protein hormone, and increases in another hormone that causes a longing for food. In addition neuropathies（神经疗法）in the brain governing sleep and fatness appear to overlap（重叠）, he said.
Patness has been rising dramatically in developed countries and reached epidemic（流行病） levels in the United States, it added, leading to a variety of health problems.

When you sit down, you pick it out. When you are in your car, you reach for it．When you’re at work, you take a break to have a moment alone with it. When you get into a lift, you play with it．
Cigarettes? Cup of coffee? No, it’s the third most addictive thing in modern life, the cell phone．And experts say it is becoming more difficult for many people to curb their desire to hug it more tightly than most of their personal relationships．
With its shiny surface, its smooth and satisfying touch, its air of complexity, the cell phone connects us to the world even as it disconnects us from people three feet away．In just the past couple of years, the cell phone has challenged individuals, employers, phone makers and counselors（顾问）in ways its inventors in the late 1940s never imagined．
The costs are becoming even more evident, and I don’t mean just the monthly bill．Dr．Chris Knippers, a counselor at the Betty Ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality．
Sounds extreme, but we’ve all witnessed the evidence: the person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him．
Is it just rude, or is it a kind of unhealthiness? And pardon me, but how is this improving the quality of life?
Jim Williams, an industrial sociologist based in Massachusetts, notes that cell-phone addiction is part of a set of symptoms in a widening gulf of personal separation．He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with．Despite the growing use of phones, e-mail and instant messaging, in other words, Williams says studies show that we don’t have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says．
If the cell phone has truly had these effects, it’s because it has become very widespread．Consider that in 1987, there were only 1 million cell phones in use．Today, something like 300 million Americans carry them．They far outnumber wired phones in the United States．Which of the following best explains the title of the passage?
| A．Cell phone users smoke less than they used to. |

| C．Cell phones have become as addictive as cigarettes. |
| D．Using cell phone is just as cool as smoking cigarettes. |

| D．cell phones do not necessarily bring people together |
What will our future look like? People have always been wondering about this question. Go on reading this text and you will know what will happen in the next fifty years.
How can we know what the future will look like? To be able to understand the future, you must know the past. What has taken us to where we are today and what has changed along the way? The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago. Will this change in the next 150 years? No.
What inventions have really made a difference in the last 150 years? In the past years, the inventions that have affected most people around the world for everyday living are the telephone, electricity, radio, television, computer, the car and the ability to communicate through the Internet. Then we of course have a lot of inventions that have made life easier, like new medicine, faster transports etc. In general, human beings have been working hard in the last 150 years to make the inventions so that they will be able to get control of the time and the world. Since there is still much to do in this area, this will be the focus at least for the next 150 years.
Why do we need to predict the future? Predicting the future is important for two reasons: first we need to start to think about what kind of what kind of future we would like for ourselves and to pass on to the next generation, and then we need to know what decisions we need to make today that will give the best result in the future.What does the author try to tell us in the second paragraph?

Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of aging as wrinkles and gray hair. But now a new book suggests that we’ve got it all wrong.
According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s — much later than previously thought.
Furthermore, rather than losing many brain cells as we age, we keep them, and even produce new ones well into middle age. For years it’s been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.
This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive (认知的) tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving. Where they performed less well was number ability and perceptual speed — how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.
Neuroscientists are also finding that we are happier with aging. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we’re younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we’ve learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.Barbara Strauch probably agrees that ______.
| A．the young are better at handling important things |
| B．people’s brains work best between their 40s and 60s |
| C．aging leads to the decline of the function of the brain |
| D．wrinkles and gray hair are the only symbols of aging |
The continuing research has found older people perform better on ______.
| A．perceptual speed | B．number ability |
| C．vocabulary tests | D．body balance |
People are happier with aging because ______.
| A．they learn to value the time left |
| B．they know how to share feelings |
| C．they cannot focus on negative aspects |
| D．they do not realize the possible dangers |
What is the main idea of the passage?
| A．People get happier with age. |
| B．People get wiser with age. |
| C．People get more forgetful with age. |
| D．People get more self-aware with age. |
Your car is a necessary part of your life. You use it every day. Of course, you want to hold on to it so you make sure it has the latest alarm and immobilizer. But despite all these, cars like yours are still stolen every day. In fact, in this country, one car is stolen almost every minute! And if your car is stolen, you only have a 50:50 chance of seeing it again.
Each year, car crime costs nearly £3 billion. Of course, if you’re insured, you won’t lose out, or will you? Firstly, you will have to pay extra insurance later on, and then you may not be offered the full amount by the agent. You will probably have to hire a car and you will also lose the value of the contents and accessories (配件) in the car.
Now comes the solution. An RAC Trackstar system, hidden in one of 47 possible secret locations in your car, is the key of our system. If your car is stolen, radio signals are sent at twenty-second intervals from the car to the RAC Trackstar National Control Center via a satellite network. Then a computer gives the vehicle’s exact location, speed and direction.
The RAC Trackstar National Control Center, which operates 24 hours a day, 365 days a year, will immediately inform the police in the area where the car is located. Because the police receive information every twenty seconds, they will always know the vehicle’s location. Once the thief has been arrested, your car will be returned to you.
RAC Trackstar is unique in being able to provide the National Control Center with details of the exact location of your car, its speed and direction. And speed is the key to successful recovery of a stolen vehicle. RAC Trackstar Control will immediately tell the police if you report your car stolen and under the 24-hour Guardian Option. It will also tell you if your car has been stolen. RAC Trackstar’s constant updates mean the police are kept informed of the car’s location. All these greatly improve your chances of seeing your car again. If your car is stolen, you will have to ______.
| A．hire a new car |
| B．pay more insurance |
| C．buy a RAC Trackstar system |
| D．inform the National Control Center |
The Trackstar system can tell the police ______.
| A．how the car is stolen | B．who the thief is |
| C．what brand the car is | D．where the car is |
The underlined word “It” in the last paragraph refers to ______.
| A．the local police station | B．the Guardian Option |
| C．the insurance company | D．the RAC Trackstar Control |
According to the passage, people with RAC Trackstar ______.
| A．automatically find directions |
| B．seldom get their vehicles damaged |
| C．have less chance of being in an accident |
| D．are more likely to get the stolen cars back |
