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 health experts 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.
D. BMI has been much questioned recently.
3.What can we conclude from the passage'?
A. It's OK to put on extra weight.
B. It doesn't matter if you are slightly obese.
C. Obese people are much healthier.
D. Body weight has nothing to do with death rates.
4.What topic does the passage mainly deal with?
A. Technology. B. Dieting. C. Health. D. Death.

There are a lot of people who are overweight all over the world. What causes obesity? If you get the gene(基因), well, probably you are going to be a few more pounds heavier compared to the rest of your classmates or friends. 1. Obesity can not only make a person look heavy, and not in the usual sense of being handsome, but can also lead to serious health conditions and life-threatening diseases.
2. Indeed, junk food has been blamed for the prevalence(流行)of obesity. It is called junk food, because hamburger, pizza and the like contain high calories. If you eat a Big Mac (a super hamburger), an order of large fries, and a large Coke, you will need to walk non-stop for six hours to burn off the calories you have gained. And don’t be fooled by soft drinks, which are high in sugar and are a major cause of obesity.
3. Popular sugary drinks, of course, include Coca Cola, Pepsi(百事) Cola, and many new brands that appear on the market every couple of days.
4. Just one 20-ounce (about 567g) bottle of soda can have 250 calories, which are equal to more than 16 teaspoons of added sugars. Even a lemon-flavored iced tea can have 210 calories.
5. Next time, when you are ready to eat that huge Mac and to drink that two-liter bottle of Pepsi, probably it’s a good idea to give it a second thought.
A. Obesity is more common in women than men.
B. Most people don’t realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)
C. When we talk about obesity, the first thought that comes to mind is: junk food.
D. The unburnt calories will put weight on you.
E. Keeping healthy is our own responsibility.
F. Because of their high content of sugar, soft drinks are also called sugary drinks.
G. However, the most common cause of obesity is eating too much, especially too much junk food.

More Australians are overweight or obese than ever before, and the number is steadily increasing. Around 64 percent of men and 47 percent of women are carrying too much body fat. This means that the chances of obesity-related disorders, such as coronary heart disease(冠心病) and diabetes(糖尿病), is also on the rise. The popularity of crash dieting has caused many misunderstandings about weight loss. Most of these misunderstandings cause unhealthy weight loss behaviors.
A recent research of deaths in the United States from their National Health Nutrition Examination Survey suggests that being overweight may not increase your risk of dying. This finding is contrary to the past research that they thought the numbers of premature death(早死) linked to weight in the year 2000. The findings were that underweight and seriously obese people have an increased chance of dying compared with normal weight people. Interestingly, however, being overweight is related to a slightly lower chance of dying for your age. The effect of obesity on death rate may have reduced over time, perhaps because of improvements in public health and medical care. The authors say that body weight may not be such an important risk factor for premature death and that fitness, while smoking and too much fat in your diet may be more important.
65. If a person carries much fat, he or she _______________ .
A.knows how to keep healthy better than those who don’t
B.should lose weight as soon as possible to keep healthy
C.will surely suffer from both coronary heart disease and diabetes
D.might suffer from some diseases related to obesity
66. The underlined phrase “is contrary to” in the second paragraph probably means ___________.
A. agrees with B. disagrees with
C. proves D. combines
67. According to the recent research of deaths in America, ______________ .
A.underweight people will live longer than those overweight people
B.dying at an early age is connected with overweight
C.being overweight doesn’t necessary lead to premature deaths
D.being overweight is healthier than normal people
68. We can infer from the text that _____________ .
A.the writer wants to persuade people not to lose weight
B.misunderstandings about weight loss are more serious than ever
C.much progress has been made in public medical condition
D.the cause of premature deaths is heavy smoking

Many people who are overweight have poor digestion(消化). For the most part, poor digestion is not a habit given by our parents. We give it to ourselves through the way we eat. Eating to get less stress or anxiety is often the mistake most people will make.
Oh, poor digestion can lead to weight problems. Here’s how: When a person feels stressed, the part of the central nervous system that connects digestion switches off. This is called the parasympathetic nervous system(副交感神经系统). At those times of stress, the body can take in food and process some of it, but digestion doesn’t work correctly to digest all the nutritional(营养的)goodness from the food. Poor digestion is not always obvious by observing symptoms; you can get some illnesses but not always. Poor digestion can be seemingly silent.
If you eat when you are stressed, anxious, or nervous, you might as well be eating cardboard for all the nutrients your body gets. Yes, eating when stressed is a gaining situation. Now you might think, well, if I’m not digesting, the calories aren’t getting handles, so I should be losing weight. Good idea, but wrong reality. When digestion is not proper, the body starts “starving” from lack of necessary nutrients(营养物). Yes, it goes into a starvation(饥饿)problem and starts absorbing(吸收) fat and energy. It thinks it’s in a famine(饥荒). The good news is that it’s easy to make some corrections and get rid of stress at mealtimes.
If you feel stressed often, it can be helpful to take other food that contains multiple B vitamins. These help, but you could still find yourself stressed at mealtimes.
1.The author wrote the passage to tell us .
A. how to deal with stress at mealtimes
B. what kind of food can be easily digested
C. eating when you’re stressed can cause weight problems
D. eating too much resulted in overweight problems
2.How do you understand the underlined sentence in the first paragraph?
A. Eating is the best way to release stress.
B. We should not release the stress by eating.
C. Eating too much can cause anxiety.
D. The stress problem can be solved during eating.
3. In what way do poor digestion and stress cause body problems?
A. Poor digestion cannot absorb much nutritional goodness from the food.
B. People with poor digestion take in food and process all of it.
C. When people feel stressed, the parasympathetic nervous system switches on.
D. Poor digestion will not lead to overweight problems.
4.Which is NOT the reason why people may have weight problems when eating with stress?
A. The body does not take in what they eat.
B. The digestion system becomes incorrect.
C. People cannot eat much when unhappy.
D. The body will begin to absorb too much fat.

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 tell whether people are lying.
C. They can understand language better.
D. They can find out the hidden drugs.

About 1 million adult New Yorkers are obese(肥胖的), but nearly two-thirds of them don’t think they are, according to a study released on Tuesday by the city’s Department of Health and Mental Hygiene(卫生).
Among the obese, who account for about one in five New Yorkers, only 39% described themselves as “very overweight”, according to the report. 2% said they were very underweight, 1% said they were slightly underweight, 16% said they were just right and 42% said they were slightly over weight.

Hypothermia can be mild, moderate or severe. Mild hypothermia is something that most people in cold climates have experienced at one time or another. You feel so cold that your body starts to shake---not very much, but uncontrollably.
The treatment for mild hypothermia starts with getting out of the cold and, if necessary, changing into dry clothes. Drinking warm, non-alcoholic liquids and eating something sugary can stop the shivering. Taking a warm bath or sitting by a fire or doing some exercise can also help the body warm up. These are all common-sense treatments.
But treatment needs to change when people enter the moderate or severe stages of hypothermia. In that situation, their body temperature drops below thirty-five degrees Celsius. They lose the ability to think clearly. Their muscles become stiff. They might bump into things or fall over objects.
Members of search-and-rescue teams will first try to prevent additional heat loss. They will place extra covering around the chest, head and neck of hypothermia victims to keep them warm.
Hypothermia victims need medical help as soon as possible. Working quickly to get people out of the cold is important. However, hypothermia victims must be moved slowly and gently. Any rough or sudden movement can force cold blood from the arms, legs and hands deep into the warmer middle of the body. This sudden flow of cold blood can create shock, a serious condition. It can also cause an abnormal heartbeat.
Members of search-and-rescue teams have a saying that hypothermia victims are not dead until they are warm and dead. The process of "rewarming" a person needs to be done slowly, in a hospital setting.
An extremely low body temperature can cause the heart to beat so slowly that a pulse may be difficult to find. In other words, a person who is suffering from the effects of severe cold may seem dead, but still be alive.
1.According to the text, when a person experience mild hypothermia, _____.
A. he feels cold so he shakes deliberately.
B. he can drink some wine to stop the shaking.
C. he should be sent to the hospital immediately.
D. some common treatments can help him recover.
2.Which of the following expression can take the place of the underlined words?
A. break into B. break down
C. knock into D. sweep up
3.When people enter the moderate or severe stages of hypothermia, which of the following statement is WRONG? _________
A. If hypothermia isn’t treated correctly, the victim’s heart may not beat normally.
B. Their body temperature drops below 35℃.
C. Hypothermia victims seem alive but dead.
D. The rescue workers should first help them warm slowly and gently in a proper situation.
4.What’s the best title for the text? _____.
A. Different kinds of hypothermia
B. Medical help is important in treating hypothermia
C. How to avoid cold-weather injuries.
D. Emergency treatment for different types of hypothermia.

Paparazzi, or "paps", are photographers who take pictures of famous people when they are not at the center of public attention. Paps are different from professional photographers or journalists because they never take ordinary photos.
The goal for paparazzi is to get pictures that no one else will get and then sell the pictures to the buyer who offers the most money —normally a small newspaper, magazine or website.
There is no law against paparazzi taking pictures in public places. However, there are laws that protect certain individuals. For example, child protection laws stop improper (不合适的) pictures of anyone under 16 from being published.
There is also no law that stops paparazzi from following celebrities (名人) and taking their pictures either. However, if paps are secretly following them and taking pictures of their faces, they could get into trouble.
Most paparazzi hang out on streets and hot spots for celebrities, waiting for the opportunity to take a picture of a star. Many stay on the streets until the early hours of the morning when celebrities are leaving nightclubs and looking a little worse for wear. However, some have other ways to make sure they get pictures. Many paps are in contact with "informers" who know the locations of celebrities at any given time. They then pass the information on to paparazzi. An informer could be anyone —from a restaurant waiter to a salesman.
Most of the time, paparazzi get a bad reputation for following celebrities. But sometimes stars or their managers will contact paps themselves and tell them exactly where and when they will go.
What a love-hate relationship between paparazzi and celebrities!
1.Which of the following things paparazzi might do would be against the law?
A.Taking pictures of famous people in public places. |
B.Getting unsuitable pictures of a 10-year-old actress published. |
C.Following a famous woman singer secretly and taking her pictures. |
D.Hanging out at the places where celebrities often appear. |
2.In order to earn big money a pap has to ________.
A.get the only first-hand pictures |
B.sell the pictures to a big newspaper |
C.make friends with famous people |
D.know the locations of celebrities |
3.The fifth paragraph mainly tells us ________.
A.how paparazzi get the pictures |
B.how dangerous paparazzi’s job is |
C.how much paparazzi pay for the pictures |
D.how paparazzi contact informers |
4.What can we infer from the passage?
A.Paparazzi always take pictures when famous people are tired. |
B.Stars hate paparazzi and don’t want to be followed. |
C.Paparazzi and famous people rely on each other sometimes. |
D.Informers might get paparazzi into trouble. |
