    A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day.
    Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later.
    Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack（缺乏）of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on （补充）sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes（糖尿病）. Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick.
    小题1:The underlined word “obese” in the first paragraph may mean       .
    A．quite protective B．very sad
    C．very fatD．quite young
    小题2:According to Chinese researchers, if a person who lacks sleep can get more sleep during weekends,       .
    A．he won’t get hungry easilyB．he will feel tired all the time
    C．there will be little chance of him becoming fat
    D．it will be very hard for him to fall asleep at night
    小题3:From the passage we know       .
    A．too little sleep will result in illness besides obesity
    B．in the past people didn’t connect sleep with weight
    C．fat children must have slept less than 10 hours five years ago
    D．most children are unhealthy because of little sleep
    小题4:What would be the best title of the passage?
    A．A good night’s sleep helps the development of kids’ brain!
    B．Ten hours’ sleep prevents overweight in kids!
    C．Children are sleeping much less nowadays!
    D．More teenagers get weight problems!
    小题5:Where can you most probably read this passage?
    A．In the latest news.B．In a children’s book.
    C．In a health magazine.D．In a scientist’s diary.

    I know what you’re thinking : pizza （比萨饼）? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to
    I know lots of women who skip breakfast （不吃早餐）, and they have a ton of different excuses for doing it . Some say they don’t have time,others think they’re “saving” calories （卡路里）, and still others just don’t like breakfast food .
    But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.
    Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southem California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
    So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it,and then you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
    小题1: The underlined word “leftovers” in Paragraph 1 probably means__________.
    A．food remaining after a mealB．things left undone
    C．meals made of vegetablesD．pizza topped with fruit
    小题2: What can we infer from the text?
    A．Working women usually have breakfast in a hurry.
    B．Many people have wrong ideas about breakfast.
    C．There are some easy ways of cooking a meal.
    D．Eating vegetables helps save energy.
    小题3: According to the last paragraph, it is important to____________.
    A．eat something for breakfastB．be careful about what you eat
    C．heat up food before eating itD．eat calorie-controlled food
    小题4:The text is written mainly for those_____________.
    A．who go to work earlyB．who want to lose weight
    C．who stay up lateD．who eat before sleep

    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.
    小题1:.The biggest difficulty in operating on the damaged brain is that ____.
    A．the time is too short for doctors
    B．the patients are often too nervous
    C．the damage is extremely hard to fix
    D．the blood-cooling machine might break down
    小题2:.The brain operation was made possible mainly by ____.
    A．taking the blood out of the brain
    B．trying the operation on monkeys first
    C．having the blood go through a machine
    D．lowering the brain’s temperature
    小题3:.With Dr. White’s new idea, the operation on the damaged brain ____.
    A．can last as long as 30 minutes
    B．can keep the brain’s blood warm
    C．can keep the patient’s brain healthy
    D．can help monkeys do different jobs
    小题4:. What is the right order of the steps in the operations?
    a. send the cooled back to the brain      b. stop the blood to the brain
    c. have the blood cooled down          d. operate on the brain
    A．a, b, c, dB．c, a, b, dC．c, b, d, aD．b, c, d, a

    Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
    Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
    Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
    Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
    If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

    A new study has been carried to test the role of story telling in lowering blood pressure．Dr．Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that investigated how pre-recorded videos of hypertension （高血压） patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months．
    Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine．They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier．Hypertension is difficult to control, since it is dependent on diet, exercise and mental state．Medical treatments with drugs, and lifestyle therapies（疗法） have been relatively ineffective because people find it hard to follow those medical requirements．
    In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate．Next, they divided their study population into two groups．One received three interactive （互动） DVDs containing the tellers' stories of their experiences in living with and treating their hypertension．The other were given educational discs on an unrelated health topic．The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure．
    While the study did not address how the story-telling influenced the patients' behavior, Houston suspects that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension．They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect．
    小题1:We can learn from the text that the pre-recorded videos _________．
    A．tell medical histories of hypertension patients
    B．introduce some medical treatments of hypertension
    C．introduce a good lifestyle for hypertensive patients
    D．tell scientific discoveries of the scientist group
    小题2:Houston was surprised to find that _______．
    A．hypertension is really difficult to control
    B．communication has some medical effects
    C．medical treatments have no effect at all
    D．people don't follow the medical requirements
    小题3:Which of the following is true about the study?
    A．The scientists chose 230 patients from a hospital．
    B．Both the groups used the same videos about health topic．
    C．The two groups lowered blood pressure in different degrees．
    D．The story-tellers were hypertension patients as well．
    小题4:Which of the following could be the best title of the text?
    A．The stories of some hypertension patients．
    B．Medical treatments of blood pressure．
    C．Storytelling may help lower blood pressure．

      Just five minutes of exercise a day outdoors can improve mental health, according to a study.
    Researchers from the University of Essex, UK have found that as little as five minutes of a “green activity” such as walking, gardening, cycling or farming could help to improve mood and increase self-esteem (自信).
    Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but the new study, led by Jules Pretty and Jo Barton, was the first to determine how much time needed to be spent on green exercise for the benefits to show.
    Barton and Pretty looked at data from 1,252 people of different ages, genders (性别) and mental health status (情况) taken from 10 studies in Britain.
    They analyzed their different outdoor activities including walking, gardening, cycling, fishing, boating, horse-riding and farming in locations such as a park, garden or nature trail (路径).
    They found that the mental health changes were seen after just five minutes. With longer periods of time exercising in a green environment, the positive effects were more apparent.
    Looking at men and women of different ages, the researchers found the health changes were particularly strong in the young and the mentally ill.
    Green and blue
    A bigger effect was seen with exercise in an area that also contained water – such as a lake or river.
    “This is because historically we are drawn to water to survive and it is in our genetic (遗传的) make-up to be at one with nature,” the researchers wrote in their report.
    Pretty said those who were generally inactive, or stressed, or with mental illness would probably benefit the most from “green exercise”.
    “Employers, for example, could encourage staff in stressful workplaces to take a short walk at lunchtime in the nearest park to improve mental health.”
    He also said exercise programs outdoors could benefit youth offenders.
    小题1:How is the study this article refers to different from other studies?
    A．It involved more people.
    B．It took longer to finish the research.
    C．It determined the exact amount of time needed.
    D．It was led by just two researchers.
    小题2: What can we conclude from the findings of the study?
    A．Just five minutes of “green exercise” daily can help improve mental health.
    B．Gardeners and farmers do not need “green exercise”.
    C．Walking in a park with a lake will weaken the effect.
    D．“Green exercise” is not suitable for the mentally ill.
    小题3:. According to Pretty, _______ would probably benefit the most from “green exercise”.
    A．stressed, inactive peopleB．office workers
    C．youth offenders D．women and children
    小题4: What is the main problem discussed in this article?
    A．Physical well-being. B．Outdoor exercise.
    C．Mental illness. D．Harmony with nature.

    Depression(抑郁症)is a serious problem today．Depression causes workers to be unproductive，causing companies and countries to lose billion of dollars．One expert says that depression is like cancer because it is “widespread, costly and deadly”．Depression hits one person in five around the world．
    Although people have believed depression to be a problem among the rich and educated，studies show that depression is a problem among everyone．Over any six-month period, between five to seven percent of the world’s population will be suffering from a serious depression．
    Suicide(自杀)rates among people suffering from the disease in its extreme, or clinical form were 80 percent higher than in the population at large, and sufferers were four times more likely to have heart attacks．People who suffer from depression often have problems sleeping，getting up on time，and doing work productively.
    Depression, which researchers agree has its origin in the genes(基因)，brings loss of confidence and ability to concentrate, making it possible for employees and managers to work efficiently．

    to see 30 or 40 patients in a morning，and just have time to say ‘Hello，how do you feel ?…’”
    In Western countries，people are not afraid to admit that they have depression，but most do not tell it to their boss，because they fear that their boss would fire them．
    “In my experience，aging bosses are the most willing to admit they have it, because they feel
    the most secure about themselves, ” an American doctor says．

    The teaching hospital is one associated with a medical school. Teaching hospitals are large, with a range of from 300 to 200 beds. These hospitals always have interns(实习医师) and residents(住院医师) and additionally have medical students on the hospital wards. They have superb technical resources, and it is here that the most extraordinary events of medicine take place. Open-heart surgery, transplantation of kidneys, elaborate(精致的) nurseries for the newborn, support for management of rare blood diseases, and other wonderful achievements are all available here. Dozens of people may be concerned with the well-being of a particular patient. Important medical decisions are thoroughly discussed, presented at conferences, and reviewed by many personnel.
    On the other hand, the quality of personal relationships at teaching hospitals is variable. Many patients feel that they are treated in an impersonal way, and that their laboratory tests receive more attention that their human and social problems. Since these institutions are on the frontier of medicine, there is a tendency to emphasize the new and elaborate procedures, when older and more modest ones might have served as well. With the inexperience of some members of the care team, there is a tendency to order more laboratory tests than what would have been ordered for the same condition in a private hospital. The sick patients are sometimes confused by having to relate to a large number of doctors and students. Medical educators are concerned with such criticisms and have to correct some of the problems. However, some excesses(超额) of technological medicine still occur in these institutions.
    小题1:One of the advantages of a teaching hospital is that         .
    A．its first-class personnel are a guarantee of excellent medical care
    B．its first-class medical facilities and skills make medical breakthroughs possible
    C．the interns, residents and medical students all offer satisfactory services
    D．its laboratory staff provide high-class professional aids for the doctors
    小题2:The passage implies that         .
    A．private hospitals usually give personalized care of high quality
    B．private hospitals have more experienced laboratory staff
    C．teaching hospitals use patients as subjects for their experiments
    D．teaching hospitals usually give patients improper treatment
    小题3:Treatments of some difficult and complicated cases in teaching hospital are decided         .
    A．by specialists in charge of the case
    B．by doctors and students together
    C．on some special and important occasions
    D．through collective efforts and serious review
    小题4: The problem that still bothers teaching hospitals frequently is         .
    A．the inadequate patient care caused by irresponsible nurses.
    B．the wrong decisions made by inexperienced doctors
    C．improper dependence on technological medicine
    D．the inconvenience caused by the presence of medical students

    Four out of ten women who diet end up heavier than when they started watching their waistline（腰围）, a study revealed today. The research also showed that a large percentage of women start noticing the pounds creeping back on just 21 days after reaching their ideal weight.
    Yesterday, Dr Ian Campbell of the Jenny Craig weight management program said: 'In the UK 61.4 per cent of adults are overweight or obese. Successful weight management requires a long-term commitment in order to lose weight successfully and for good. Dieting can be a real challenge so setting realistic goals and remaining focused on them is important. Otherwise as this research shows, women could end up heavier than when they started.'
    The 'Food: Body: Mind' report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss. Six in ten said they are currently on a diet and one in five women said they are on a 'continuous diet'.
    It found the most common triggers to start dieting was seeing their 'reflection in the mirror', preparing for a summer holiday or unflattering photos posted on social networking sites. Other popular reasons include comments by friends or relatives or their other half.
    However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more. The average is ten days. Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal. Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers who polish off their children's leftovers was another common cause of weight gain.
    小题1:Which of the following might be the best title for this article?
    A．Three reasons to fail in dietingB．Important things for successful diet
    C．Four in ten women gain weight on dietsD．Obesity: problem for 61.4% adults in UK
    小题2:In the UK, women who go on a diet __________.
    A． are all overweight or obese
    B． all fail because they are not persistent enough
    C． are likely to gain weight again after reaching their ideal weight
    D． end up heavier than when they start to diet
    小题3:The underlined word “triggers” in Paragraph 4 probably means_________.
    A．effects B．causesC． examplesD．imagination
    小题4:Which of the following is NOT the reason why many people quit dieting very soon?
    A．The pressure they put on themselves to lose weight quickly.
    B．Colleagues who give them fatty lunches and snacks.
