    “An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
    The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
    Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
    These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
    There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.

    With the pace of life continuing to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, it is hard to slow down. But relaxation is essential for a healthy mind and body.
    Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
    The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.
    小题1:People are finding less and less time for relaxing themselves because_____.
    A．they do not know how to enjoy themselves
    B．they do not believe that relaxation is important for health
    C．they are travelling fast all the time
    D．they are becoming busier with their work
    小题2:According to the writer, the most important character for a good manager is his ________.
    A．not fearing stress
    B．knowing the art of relaxation
    C．high sense of responsibility
    D．having control over performance
    小题3:Which of the following statements is true?
    A．We can find some ways to avoid stress
    B．Stress is always harmful to people
    C．It is easy to change the habit of keeping oneself busy with work.
    D．Different people can withstand different amounts of stress
    小题4:In Paragraph 3 "such a reaction" refers back to_______.
    A．"making a choice between 'flight' or 'fight'"
    B．"reaction to stress both chemically and physically"
    C．"responding to crises quickly"
    D．"losing heart at the signs difficulties"
    小题5:What does the author think of stress?
    A．Stress is a bad thing.
    B．Different people can withstand the same amount of stress.
    C．A certain amount of stress is not a bad thing.
    D．Our health will become endangered if we cannot remove stress.

    As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease—especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious (有营养的) foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
    The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well” in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.
    小题1:Today medical care is placing more stress on ________.
    A．keeping people in a healthy physical condition
    B．monitoring patients’ body functions
    C．removing people’s bad living habits
    D．ensuring people’s psychological well-being
    小题2:In the first paragraph, people are reminded that ________.
    A．good health is more than not being ill
    B．drinking, even if not to excess, could be harmful
    C．regular health checks are essential to keeping fit
    D．prevention is more difficult than cure
    小题3:Traditionally, a person is considered “well” if he ________.
    A．does not have any unhealthy living habits
    B．does not have any physical handicaps
    C．is able to handle his daily routines
    D．is free from any kind of disease
    小题4:According to the author, the true meaning of “wellness” is for people ________.
    A．to best satisfy their body’s special needs
    B．to strive to maintain the best possible health
    C．to meet the strictest standards of bodily health
    D．to keep a proper balance between work and leisure
    小题5:According to what the author advocates, which of the following groups of people would be considered healthy?
    A．People who have strong muscles as well as slim figures.
    B．People who are not presently experiencing any symptoms of disease.
    C．People who try to be as possible, regardless of their limitations.
    D．People who can recover from illness even without seeking medical care.

    Lots of people are unhappy with their present weight, but most aren't sure how to change it. You may want to look like the models or actors in magazines and on TV, but those goals might not be healthy or realistic (现实的) for you. Being healthy is really about being at a weight that is right for you. The best way to find out if you are at a healthy weight or if you need to lose or gain weight is to talk to a doctor or dietitian（营养学家）. If it turns out that you can benefit from weight loss, then you can follow a few of the simple suggestions listed below to get started.
    _______________________. Ask your mom or dad to lend help and support and to make lifestyle changes that will benefit the whole family, if possible. Those who have the support of their families tend to have better results with their weight-management programs.
    Watch your drinks. It’s amazing how many extra calories can be in the sodas, juices and other drinks that you take in every day. Simply cutting out a can of soda or one sports drink can save you 150 calories or more each day. Slake yourself with water or other sugar-free drinks when you’re thirsty and stay away from sugary juices and sodas.

    It takes more than just practice to become an Olympian. Gold medal performances require some serious nutrition. Have you ever wondered what these successful athletes eat to stay in peak shape?
    Keri Glassman, a registered dietitian and founder of Nutritious Life Meals, appeared on “Good Morning America” today to give you a glimpse into the diets of some top athletes. Some of their meals could surprise you.
    Crazy Calorie Count
    Glassman said Olympians eat a lot of food- quantities that for ordinary people would constitute pigging out. One secret of swimmer Michael Phelps’ astonishing performance in the 2008 Olympics in Beijing was consuming as many as 12,00 calories in one day.
    Athletes can eat like this and not gain any weight because their workouts are intense. According to Glassman, Phelps’ workouts can burn 4,000 to 6,000 calories in a day, and those calories must be added in order to train the following day.
    Snacking Secrets
    Some athletes eat strange foods that improve their performance. Yohan Blake, the Jamaica sprinter and 100-meter world champion, has stolen champion sprinter Usain Bolt’s thunder on the track during the Olympic trials. Asked about how he gets his energy, Blake answered that he eats 16 bananas per day ,Glassman said.
    Jonathan Horton, the lead gymnast on the Us team, has a blood sugar problem. His solution is honey. When he starts to feel shaky at the gym, he takes honey to boost his energy, Classman said.
    Foods for Recovery
    What are the best foods to help the body recover after harsh competition?
    For Olympic swimmer Ryan Lochte, the recovery meal is grilled chicken breasts with Alfredo sauce, whole-grain spaghetti and a salad with lemon juice and olive oil. Lochte, who recently cut out junk food, candy and soda, has undertaken a strength-training regimen(养生法)that involves flipping tractor tires, and tossing beer kegs, Glassman said.
    小题1:What’s the best title of this passage?
    A．Good Diet Makes a True Olympian.
    B．Olympians Have Olympic-size Appetites.
    C．The Diet of Some Top Olympic Athletes.
    D．Olympians’ Strange Eating Habits.
    小题2:What does the underlined sentence probably mean?
    A．Ordinary people eat few pigs compared with Olympians.
    B．Olympians eat a lot more food than ordinary people.
    C．Olympians tend to eat a lot of high-quality food.
    D．Olympians eat a large amount of food, just like pigs.
    小题3:Which of the following is TRUE according to the passage?
    A．Ryan Lochte quit eating junk food , candy and soda for his better recovery.
    B．Yohan Blake finally beat Usain Bolt in the 100-meter track in the Olympics.
    C．Michael Phelps’ astonishing performance was due to his eating lots of food.
    D．Jonathan Horton has a blood sugar problem because of taking too much honey.
    小题4:The passage is most likely to be found in     .
    A．a technical reportB．a fashion magazine
    C．an education columnD．a sports newspaper

    If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory（记忆力） is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
    小题1:The main reason for one’s poor memory is that _______.
    A．his father or mother may have a poor memory
    B．he does not use his arm or legs for some time

    D．he can’t read or write

    D．they will become neither stronger nor weaker
    小题3:Which of the following is NOT true?
    A．Your memory works in the same way as your arms or legs.
    B．Your memory, like your arms or legs, becomes weak if you don’t give it enough chance for practice.
    C．Don’t learn how to read and write if you want to have a better memory.
    D．A good memory comes from more practice.
    小题4:Some people can’t read or write, but they usually have better memories, because _______.
    A．they have save much trouble
    B．they have saved much time to remember things
    C．they have to use their memories all the time
    D．they can’t write everything in a little notebook
    小题5:Which is the best title for this passage?
    A．Don’t Stop Using Your Arms or LegsB．How to Have a Good Memory
    C．Strong Arms and Good MemoriesD．Learn From the People

    I fell in love with Yosemite National Park the first time I saw it, when I was 13. My parents took us there for camping.

    Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.
    In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.
    Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.
    Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.
    In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.
    小题1:Vitamin supplements are popular with people because ________. 
    A．people mistakenly think that they are good for their health
    B．they contain more vitamins than the foods people eat
    C．food does not provide enough vitamins people need
    D．people fear that a lack of vitamins will lead to disease
    小题2:From the passage, we can learn that medical experts advise people _________.
    A．never to take any vitamin supplements
    B．to depend only on food for their vitamins
    C．not to take any vitamins together with medicines
    D．to consult doctors before taking vitamin supplements
    小题3:For people who lack Vitamin B-twelve, they can eat more from _______.
    A. sweet potatoes   B. pork products   C. green leafy vegetables  D. eggs
    42. What would be the best title of the passage?
    A. Getting enough vitamins through a balanced diet.
    B. Vitamin supplements do harm to our health.
    C. Vitamins are important to our health.
    D. Lacking vitamins can cause many diseases.
