People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals(个人;个体), according to a new analysis of nearly 100 international studies.
The studies, most conducted within the past decade, included about three million adults from around the world. The result of these studies by researchers at the National Center for Health Statistics in Maryland, part of the U.S. Centers for Disease Control and Prevention, shows that slightly overweight or obese people were six percent less likely to die from all causes compared to people of normal weight. But the researchers found that seriously obese individuals were still at a 30 percent greater risk of death compared to healthy-weight individuals.
Study lead author Katherine Flegal says she was not surprised that overweight people would not have a higher death risk. “Because we'd actually already read a lot of this literature and realized that death rates for overweight would be at least not higher than normal[weight," she said. “I guess l was a little bit surprised that it was definitely lower. And l was also surprised that the lower rates of obesity didn't seem to differ from normal weight."
But Flegal stresses the difference in death rates appear to be small between normal-weight people and overweight and mildly obese individuals.
The finding by Flegal and colleagues have raised new questions about the reliability(可靠性)of the so-called "body mass index" or BMI, a measurement of body fat as a ratio(比例,比率)of height to weight, that has become popular in recent years among public healthexperts to measure potential health risks.
But Heymsfield warns that individuals should not conclude that it's okay to put on extra kilograms, since being at a healthy weight lowers the risk for heart disease and diabetes.
1.Katherine Flegal feels surprised at the fact that____.
A. obese people have higher death rates
B. slightly obese people have lower death rates
C. obese people tend to die early
D. death rates have nothing to do with body weight
2.What do we learn from the fifth paragraph?
A. BMI may not be so reliable.
B. The study provides further evidence for BMI.
C. BMI tells nothing about potential health risks.

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.
Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.
The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.
Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.
“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”
But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.
The study has raised new questions about “body mass index,”(体重指数) or BMI. This is a measurement of body fat as a ratio(比率) of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.
Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.
Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes(糖尿病).
1.According to the new findings, the researchers found that __________ .
A.People with high obesity have a lower risk of early death than people with low obesity
B.People with overweight have a greater risk of early death than people of normal weight.
C.People with mild obesity are less likely to die than people of normal weight.
D.People with obesity live much longer than people of normal weight.
2.What does the underlined word “literature” in paragraph 6 mean ?
A.works like novels and poems
B.books and articles on a particular subject
C.printed material
D.magazines and newspapers
3.Which of the following statements is not true according to the passage?
A. BMI is commonly used to measure body fat as a ratio of height to weight.
B. Not all people with a little higher BMI are fat .
C. Many public health experts encourage more people to use BMI as a way to predict the risk of health problem
D. Because of the ne w findings, people should think about gaining extra weight.

Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up. So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem.
The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated (使…等同) with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.
So what do you do? Diet? Not according to England's chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people's lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.
There's new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely (oppositely) affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.
So, should we forget about gyms and follow some expert's advice to reduce sedentary (久坐不动的) activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today?
1.Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.
A. beauty should be overweight
B. a fat man is usually a cheerful character
C. fatness was considered something good at one time
D. fatness leads to an increased risk of disease
2.According to Sir Liam Donaldson, we should_____.
A. go on a diet B. do regular physical activity
C. give up smoking D. go to the gym
3.The underlined phrase cross trainers probably refers to _____.
A. people who help you do exercise B. places where you can do exercise
C. a kind of shoes D. a form of vehicles
4.At present being overweight indicates _____.
A. an increased risk of diseases B. a happier life
C. a cheerful character D. a beauty
5.What is the passage mainly about?
A. how to keep fit and avoid fatness. B. increased risks for overweight people.
C. the dangers of exercise in the gym. D. the benefit of a balanced diet.

An estimated 60 percent of cats and 50 percent of dogs in the U. S. are overweight or obese, so chances are that your pet needs to lose weight rather than pack on some pounds. It's not always easy to tell if your pet could afford to lose few, but there are some other signs that can tip you off. One important factor the waist, "Most people don't know what a normal cat should look like," says Romine. "But cats should have waists, too." The vet says you should be able to feel your pet's ribs(肋骨) through its coat, and when you look down at them, they should have an hourglass(沙漏)shape---just like person.
"For some overweight pets, you may want to switch to new food entirely; foods with 'light' or 'healthy weight' labels usually have an increased fiber content to help the dog or cat feel fuller," Romine notes. "Another option is to feed them less of the food they currently cat," Freeman suggests. "Make sure you're reducing table scraps(残羹剩饭)and high-calorie treats like pet biscuits," she says.
It's important to figure out what your pet's ideal weight is as you're helping them to lose. Romine advises working with your vet to get the right number, and if you're following the portion guidelines often printed on food labels, feed them the amount of food associated with the weight you want them to be, rather than the weight they currently are.
Food isn't the only factor that can impact your pet's weight. Romine stresses the importance of exercise in keeping your pet healthy. For cats, just 10 minutes of indoor play each day can make a difference. For dogs, letting them out in the backyard to do their business is not enough. You'll have to exercise with your dog to really get them moving.

Doctors have a new weapon in the battle against obesity (过度肥胖) — a talking plate that tells people not to eat too quickly. The Mandometer monitors the amount of food leaving the plate, and tells users, “Please eat more slowly.”
The £1,500 Swedish device is to be used in a National Health Service plan to help hundreds of obese families lose weight. It comes in two parts — a scale placed under the plate and a small computer screen showing a graphic(图表) of the food gradually disappearing as the user eats. A red line on the screen shows the user’s eating speed, while a blue line shows a healthy rate. If the user eats too fast, the red line angles away from the blue one, warning him or her to ease off. If the lines deviate (偏离) too much, the computer voice comes on, and the screen flashes the message “Are you feeling full yet?” to remind users to think about whether they have had enough.
Britain has an increasingly serious obesity problem, with one in four adults and one in seven children classed as obese. After a recent trial using the device, experts believe teaching obese people to eat more slowly will help them know when they are full. Around 600 families with at least one obese parent and child (aged five or older) were targeted in the project by Bristol University, along with GPs and nurses.
Professor Julian Hamilton-Shield, who is leading the plan, says obese children and adolescents using the Mandometer ate from 12 to 15 percent less per meal at the end of the 12-month trial. Six months after they stopped using the device they still ate less, and continued to lose weight. “It will be a powerful tool to help families retrain their eating habits,” he says.
1. What does the red line on the screen show?
A. A healthy rate of eating. B. Too much food is left.
C. The user’s eating speed. D. The user is full.
2. What can we infer from the text?
A. The device can help obese people form good eating habits.
B. Every family will have such a device soon.
C. This device is the best way to lose weight.
D. People will no longer worry about obesity.
3. The underlined phrase ease off is closest in meaning to ______.
A. to become less tense B. to eat more slowly
C. to remove gently and slowly D. to stop
4. Which of the following is TRUE, according to the text?
A. 25% of children are obese in Britain.
B. One in seven adults is obese in Britain.
C. Children using the Mandometer ate less after the trial.
D. Six months after the trial, obese people are still eating a lot.

Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.

People who have lost the ability to understand or use words due to brain damage are called aphasics(失语症患者).Such patients can be extremely good at something else.From the changing expressions on speakers’ faces and the tones of their voices,they can tell lies from truths.
Doctors studying the human brain have given a number of examples of this amazing power of aphasics.Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.
Recently,scientists carried out tests to see if all that was said about aphasics was true.THEY STUDIED A MIXED GROUP OF PEOPLE.Some were normal;others were aphasics.It was proved that the aphasics were far ahead of the normal people in recognizing false speeches—in most cases,the normal people were fooled by words,but the aphasics were not.
Some years ago,Dr.Oliver Sacks wrote in his book about his experiences with aphasics.He mentioned a particular case in a hospital.Some aphasics were watching the president giving a speech on TV.Since the president had been an actor earlier,making a good speech was no problem for him.He was trying to put his feelings into every word of his speech.
But his way of speaking had the opposite effect on the patients.They didn’t seem to believe him.Instead,they burst into laughter.The aphasics knew that the president did not mean a word of what he was saying.He was lying!
Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words.However,according to Dr.Sacks,they are more gifted than normal people.Normal people may get carried away by words.Aphasics seem to understand human expressions better,though they cannot understand words.
1.What is so surprising about aphasics?
A.They can fool other people. B.They can find out the hidden drugs.
C.They can understand language better. D.They can tell whether people are lying.
2.How did the scientists study aphasics?
A.By asking them to watch TV together.
B.By organizing them into acting groups.
C.By comparing them with normal people.
D.By giving them chances to speak on TV.
3.What do we learn from this text?
A.What one says reflects how one feels.
B.Aphasics have richer feelings than others.
C.Normal people often tell lies in their speeches.
D.People poor at one thing can be good at another.

高三英语阅读理解中等难度题查看答案及解析
Your peers are people your age or close to it who have experiences and interests similar to yours. You and your friends make dozens of decisions every day, and you influence each other’s choices and behavior. This is often ________ --- it’s human nature to listen to and learn from other people in your age group.
Sometimes, though, the stresses in your life can actually come from your peers. They may pressure you into doing something you’re uncomfortable with, such as shoplifting, doing drugs or drinking, or taking dangerous risks when driving a car.
The pressure to conform(随潮流) can be powerful and hard to resist. A person might feel pressure to do something just because others are doing it. Peer pressure can influence a person to do something that is relatively harmless--- or something that has more serious consequences.
People may feel pressure to conform, so they fit in or are accepted, or so they don’t feel awkward or uncomfortable. When people are unsure of what to do in a social situation, they naturally look to others for cues(暗示)about what is and isn’t acceptable.
The people who are most easily influenced will follow someone else’s lead first. Then others may go along, too --- so it can be easy to think, “It must be OK. Everyone else is doing it. They must know what they’re doing.” Before you know it, many people are going along with the crowd --- perhaps on something they might not otherwise do.
Responding to peer pressure is part of human nature --- but some people are more likely to give in, and others are better able to resist and stand their ground.
It’s not always easy to resist negative peer pressure. But when you do, it is easy to feel good about it afterwards. And you may even be a positive influence on your peers who feel the same way --- often it just takes one person to speak out or take a different action to change a situation.
1.Which of the following is a kind of peer pressure?
A.Your teachers give you a lot of homework.
B.Your parents expect high scores from you.
C.Your classmates persuade you to cut class.
D.Your relatives invite you to attend a party.
2.Which is most likely to be filled in the blank in Paragraph 1?
A.negative
B.impossible
C.positive
D.uncertain
3.Most people tend to do what others are doing in order to _________.
A.feel a sense of achievement
B.get a feeling of being accepted
C.set a good example for others
D.stand out in a crowd
4.What can we know according to the author?
A.Giving in to peer pressure is unavoidable.
B.Peer pressure usually leads to serious results.
C.Going along with the crowd usually means making a right choice.
D.Everyone can make a difference by resisting negative peer pressure.
5.This passage is mainly about _______.
A.thoughts on peer pressure
B.different types of peer pressure
C.ways to deal with peer pressure
D.the influence of peer pressure on people
