    Smaller than your fist, your healthy heart just goes on and on. It will beat more than 60 times a minute for 70 years or more. That’s something that most of us take for granted. But it’s an amazing fact.
    60 times a minute for 60 minutes is 3,600 times. What physical thing can most of us do 3,600 times in one hour? Blink? Maybe. Tap our fingers on the desk? No. Jump up and down? Certainly not! But our heart keeps beating, hour after hour. Every day, it pumps almost 2,000 gallons of blood through our blood vessels(血管). It takes you about five years to drink 2,000 gallons of water.
    And, unlike your knees or your back, your heart does all this work without ever complaining（抱怨）! You never know that it’s even there. Your heart is such a reliable “silent partner” that people forget to care for it. For many, the first indication（迹象）that their heart isn’t working properly is a serious heart illness! Over 650,000 Americans die of some kind of heart disease every year. Cancer kills 560,000, stroke kills 143,000, and accidents kill 118,000 Americans annually.
    Like accidental deaths, many heart disease-related deaths can be avoided if people simply follow the advice of the experts. Unfortunately, most people seem to listen to a little voice in their head that says, “It won’t happen to me. ” So these people keep on smoking and drinking. They continue to eat too much meat. And their only “exercise” is getting off the sofa to get something out of the fridge. Please follow the following steps to keep your heart healthy.
    小题1:The text is most probably taken from a (an) __________.
    A．art bookB．science fiction

    B．In America, heart disease causes the highest death rate annually.
    C．Cancer causes more threat than any other diseases for Americans.
    D．Recently, nobody died of stroke or heart disease in America.

    How often do you go on holiday? Going on holiday makes you feel good while you're there－you gain the health benefits for months, new research shows.
    Jetting off to exotic destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress, it found. The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed. Experts say workers should always take their full holiday entitlement each year－as many as one in three don't－to get the benefits.
    The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with people who stayed at home and continued working. The average blood pressure of those on holiday dropped by 6% while the workers saw their blood pressure rise by 2% over the same period. The sleep quality of holiday-makers improved by 17% while that of the non-holidaymakers deteriorated by 14%.
    The study also found the ability of vacationers to recover from stress—known as the stress-resilience test－improved by 29%. There was a 71% fall in stress resilience scores among workers. Test showed a fall in blood glucose levels, reducing the risk of diabetes, trimmer waistlines and enhanced mood and energy levels, with the effects sustained for at least 2 weeks after returning home.
    The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK's largest healthcare charity.
    小题1: The author intends to tell us that _____.
    A．it is best to go to foreign countries like Maldives.

    Good Housekeeping has discovered that even if a child wear a helmet when she bikes, or skates, it may not protect her from a serious head injury.
    Every year, 390,000 children under age 15 go to hospital emergency rooms with bike-related injuries. Of that number, about one third children suffer head injuries and an estimated 200 die. By wearing a helmet, a child can reduce her risk of injury by as much as 85 percent. But remember —— a bicycle helmet must fit properly to be safe. Here are five steps to making sure your child's helmet fits properly.
    1) If you haven't bought your child's helmet already, you might want to consider one with a rear stabilizer(稳定杆). A rear stabilizer holds the back of the head gently and helps the helmet stay correctly positioned.
    2) The helmet should fit closely and shouldn't slide from side to side or front to back. If your child can put two fingers on both temples inside the helmet, it's too big. Try a smaller size. But if the next size down is too small, use the fit pads(护垫). Fit pads come in different sizes and attach to the helmet with Velcro.
    3) Tell your child to open her mouth widely and ask if she can feel the helmet push down onto the top of her head. If she can't, you need to readjust her helmet.
    4) To prevent strap slippage, wind a rubber band around the strap where it meets the fastener.
    5) Recheck the fit regularly.
    You should replace the bicycle helmet:
    If she has been in an accident with it.
    If the buckle(金属扣) breaks or if a piece breaks off.
    If it doesn't have a U.S. Consumer Product Safety Commission, American Society for Testing and Materials, or Snell Memorial Foundation sticker.
    If it doesn't fit correctly. Even if the helmet fit perfectly two years ago, it might be too small now.
    小题1:Who is this passage mainly written for?
    A．Children.B．Teachers.C．Parents.D．helmet producers.
    小题2:What does the author mainly want to stress in the second paragraph?
    A．The bike-related injury is a serious threat to the children.
    B．The bicycle helmets must fit properly while the children are biking.
    C．It’s necessary for the children to wear helmets while biking.
    D．Many students suffer bike-related injuries every year.
    小题3:If a girl finds a helmet a little bit big for her head, what should she do?
    A．She must buy a smaller size.
    B．She can use some fit pads.
    C．She can put fingers on both temples inside the helmet.
    D．She must make helmet slide from side to side.
    小题4:Phil White, a father, found the buckle of his girl’s helmet broken, he can_______
    A．buy a new bicycle helmet for her
    B．mend the bicycle helmet himself
    C．continue to use the bicycle helmet
    D．throw away the broken buckle

    You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community.
    "How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself.
    The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison.
    Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself.
    The reasons that yoga causes "serious injury”, according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures.
    Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there.
    We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer.
    小题1:The underlined word is best replaced by __.
    A．InjureB．BenefitC．PushD．Shape
    小题2:What does author mainly want to tell us in the 3rd paragraph?
    A．All physical activities are equally harmful.
    B．Yoga causes much less injuries than other physical activities.
    C．Similar researches have been done before.
    D．Yoga, like any other form of exercise, can hurt people.
    小题3:Which is not mentioned among the reasons for yoga being likely to cause injury?
    A．Teachers lack the knowledge of students’ limits.
    B．Modern lifestyle decreases our flexibility.
    C．The body doesn’t tell when you are in real pain.
    D．Students themselves might not be in good physical condition.
    小题4:What is the author’s attitude towards practicing yoga?
    A．It’s a shame not to practice yoga.
    B．One should push the limits in order to be perfect.
    C．The majority should give up yoga for it may cause harm.
    D．One should enjoy the physical and mental benefit that yoga brings.

    WASHINGTON－School lunches have been called many things, but a group of retired military officers is giving them a new label: national security threat.
    That's not a reference to the mystery meat served up in the cafeteria line either. The retired officers are saying that school lunches have helped make the nation's young people so fat that fewer of them can meet the military's physical fitness standards, and recruitment will be difficult.
    A new report being released Tuesday says more than 9 million young adults, or 27 percent of all Americans ages 17 to 24, are too overweight to join the military. Now, the officers are advocating for passage of a wide­ranging nutrition bill that aims to make the nation's school lunches healthier.
    The military group acknowledges that other things keep young adults out of the armed services, such as a criminal record or the lack of a high school diploma. But weight problems that have worsened over the past 15 years are now the leading medical reason that recruits are rejected.
    Although all branches of the military now meet or exceed recruitment goals, retired Navy Rear Adm. James Barnett Jr., a member of the officers group, says the obesity trend could affect that.
    “When over a quarter of young adults are too fat to fight, we need to take notice，” Barnett said. He noted that national security in the year 2030 is “absolutely dependent” on reversing child obesity rates.
    This isn't the first time the military has gotten involved in the debate over school lunches. During World War Ⅱ， military leaders had the opposite problem, reporting that many recruits were rejected because of stunted growth and inadequate nutrition. After the war, military leaders pushed Congress to establish the national school lunch program so children would grow up healthier.
    Today, the group is urging Congress to eliminate junk food and high­calorie beverages from schools, put more money into the school lunch program and develop new strategies that help children develop healthier habits.
    小题1:What is the main problem of the lunches in schools according to the military officers?
    A．The meat in the lunches is mysterious.
    B．The lunches are too expensive.
    C．The lunches contain too much fat.
    D．There is inadequate nutrition in the lunches.
    小题2:The underlined word “obesity” in Paragraph 5 means ________.
    A．slow in mind B．state of being fat
    C．quick in movementD．lack of confidence
    小题3:Which of the following statements is NOT true?
    A．The lunches in American schools are not very healthy.
    B．During World War Ⅱ，many people could not join the army because of overweight.
    C．According to the author , overweight was the key reason why many recruits were rejected.
    D．By now, Congress hasn't eliminated junk food and high­calorie beverages from schools.
    小题4:Which of the following is the best title for the article?
    A．School lunches: a national security threat?
    B．National security in danger ?
    C．Retired officers tired of school lunches
    D．The recruitment of 2030

    Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
    Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.
    However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
    Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It's not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said，"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.
    小题1:What information can we get from the first two paragraphs?
    A．Brown fat stores calories and makes us fatter
    B．It doesn't take long to turn white fat into brown.
    C．Social excitement helps gain more weight
    D．Brown fat can burn energy to produce heat.
    小题2:Which of the following statement does the text support?
    A．Levels of brown fat can be increased by socializing.
    B．The mice lacking social life lose more weight.
    C．The research findings haven't been published so far.
    D．Dr Matthew During wasn't convinced of the result.
    小题3:We can conclude from the text that _______.
    A．the fat in mice's belly was reduced because of the relaxing environment
    B．a sedentary lifestyle and high calories foods influence people's social life
    C．surfing the Internet may influence people's face-to-face communication
    D．cancer and death are mainly caused for lack of social life
    小题4:What’s the main idea of the text?
    A．Brown fat is beneficial to people's health.
    B．Socializing is unnecessarily important in people's daily life.
    C．White fat can be changed into brown fat.
    D．Socializing contributes to people's losing weight.

    Weighed down by study? Pushed to the limit by the fast pace of life ? Frightened by the possible war ? Well, you’re not alone. Men and women in France are seeking relief using the world’s best medicine-----laughter.
    In the past year, more than 15 laughter clubs have been set up across the country. People of all ages go to release their stress with an hour group laughs. “People telephoned me and said they have forgotten what it is to laugh. They want to find a place where they can escape all their problems for a while. So they come,” said 40—year—old Jocelyne Le Moan. She usually takes a class of around 60 people through a series of laughter techniques.
    Her pupils range from teenagers to 70 years old, but most are middle---aged white collars seeking 60 minutes of relaxation at the end of a busy day. Le Moan takes them through the “Lion Laugh”and the “Laugh Contest”, where participants “speak”to each other in different ways. And instead of talking, they break into fits of laughter. At the end there are 15 minutes of “meditation”, when they lie on their backs and let the laughs burst out of their mouths.
    “I love it. It’s an experience that has changed my life. Through it I rediscovered the child’s laugh inside me,”Said Romain Jouffroy, 24. “US President George W. Bush should give it a try. He has lost his laugh,”she joked . Like Jouffroy, many laughter club members find themselves changed into children again, and why not ? The average preschooler laughs up to 400 times a day.
    The average adult only a day seven to 15.
    The physical benefits of laughter are already well—recognized. Doctors say the act of laughing releases good chemicals into the blood—stream, while the quick breathing that accompanies it helps massage（按摩）the digestive organs and strengthens the heart.
    “A full hour is like having your inside go jogging！One finishes out of breath, but feels revitalized（产生新活力. And on top of that , you’ve had a laugh,”said doctor Alexisd’ Estaing.And many participants in Paris also emphasize the psychological benefits. They believe that laughter is a way of making oneself feel more confident.
    小题1:Which of the following is not included among the benefits of laughing?
    A．It can make people rediscover their children’s laugh.
    B．It can release good chemical into blood streams.
    C．It can make you feel self—confident.
    D．It can cure the illness of people.
    小题2:The writer suggested that you should_____________.
    A．take the world’s best medicine.
    B．talk to each other about what troubles you.
    C．learn series of laughter techniques.
    D．have a good laugh after a busy day.
    小题3:From the passage , we can conclude the following but___________.
    A．Jocelyne Le Moan is a teacher of the club.
    B．the members are mostly middle---aged white collars.
    C．people always need some way to relax in life.
    D．laugh freely and everything goes well.
    小题4:Which of the following is not the reason why so many people join the laughter clubs ?
    A．Those members feel too much pressure on them.
    B．They want to find a place to relax themselves.
    C．Laughters help massage the digestive organs.
    D．The members don’t know how to laugh.
