There's a lot of discussion these days about healthy kids. People who care (parents, doctors, teachers, and others) want to know how to help kids be more healthy.
Being healthy is a way of saying a person eats well, gets a lot of physical activity (exercise), and has a healthy weight. If you're healthy, your body works well, feels good, and can do all the things you want to do. Here are five rules to live by, if you're a kid who wants to be healthy.
Eat a Variety of Foods, Especially Fruits and Vegetables. You may have a favorite food, but the best choice is to eat a variety. If you eat different foods, you're more likely to get the nutrients(營養(yǎng)) your body needs. Taste new foods and old ones you haven't tried for a while. Get at least five servings of fruits and vegetables a day — two fruits and three vegetables.
Drink Water and Milk Most Often. When you're really thirsty, cold water is the No. 1 for you. Kids need calcium（鈣）to build strong bones, and milk is a great source of this mineral. How much do kids need? Aim for 3 cups of milk per day. You can mix it up by having milk and some other calcium-rich dairy foods .
Be Active.One job you have as a kid — and it's a fun one — is that you get to figure out which activities you like best. Not everyone loves baseball or soccer. Ask your parents to help you do your favorite activities regularly. Find ways to be active every day. You might even write down a list of fun stuff to do, so you can refer to it when your mom or dad says it's time to stop watching TV or playing computer games!
小題1: What’s the best title for this passage?
A．Do Your Favorite Activities RegularlyB．Eat More Fruits and Vegetables Every Day
C．Drink Water and Milk When You Are ThirstyD．Tips on How to Keep Healthy
小題2: Which of the following can’t show a kid is healthy?
A．Eating wellB．Having too much sleep
C．Having a healthy weightD．Getting a lot of physical exercise
小題3: The best way to get enough nutrients for your body is ________.
A．to drink milk every dayB．to eat what you haven’t eaten before
C．to eat all kinds of foodsD．to eat fruits and vegetables instead of grains

Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle.
Keep a scientific diet. Keep in mind that sugar can be removed from our diet completely. Over intake of sugar is one of the main reasons for getting fat. Over intake of protein or fat and low intake of fiber can also lead to getting fat. We need only a few grams of protein every day to keep our body in order. Like rain to crops, not the more the better.
Be always in a good mood. There is a relationship between the mood and health. A good mood keeps you in high spirits. Thanks to the Internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains, enjoy music and movies and chat with some good friends. Just keep happy.
Enough sleep. Two studies show the reasons why teens and adults don’t have enough sleep. With teens, a major reason is mobile phone use; with adults, it’s work. Meanwhile, a third study of young children shows that a lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover from tiredness and the hurt caused by hard work in the daytime.
Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of modern life, you don’t have time to do exercise every day, but at least three times a week and 45 minutes each time.
小題1:The author wrote the passage to _______.
A．tell the readers how to take proper exercise every day

Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result: thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings.
Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.
The study is in the New England Journal of Medicine. Kirsten, at the University of California, was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium, which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows how that idea can influence what parents order for their children.
Ninety-nine parents of three to six year olds took part. Half had McDonald's menus clearly showing how many calories were in each food. The other half got menus without the calorie information.
小題1: How many heart attacks will occur in the US every year？ 
A．nearly 800,000.B．24,000.
C．100,000.D．92,000.
小題2:We can learn from the passage that         .  
A．Americans ate no more than 5 grams of salt per day in the 1970s
B．the American Heart Association suggest less than 3 grams of salt every day
C．a(chǎn) reduction in salt in the diet helps lower blood pressure
D．a(chǎn)ll the heart diseases result from eating more salt
小題3:The National Salt Reduction Initiative aims to         . 
A．a(chǎn)dvise Americans to eat less salt
B．put pressure on food companies and restaurants
C．require fast food places to list calorie information
D．a(chǎn)ttract the public attention to the problem
小題4:All the following are related to the salt in diet except         .  
A．strokesB．heart attacks
C．blood pressuresD．stomach diseases
小題5:The best title of the passage of the passage is         . 
A．Less salt can mean more life
B．Prevent heart attacks and deaths
C．The National Salt Reduction Initiative
D．Americans should eat less salt

I know what you’re thinking : pizza （比薩餅）? 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.
小題1: The underlined word “l(fā)eftovers” in Paragraph 1 probably means__________.
A．food remaining after a mealB．things left undone

Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment．Here are some guidelines to follow:
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from．Besides so many choices, we now hear about our "food print", the amount of land needed to supply one person's nutritional needs for a year．Do we buy cherry tomatoes from Mexico or tomatoes grown locally in a hothouse? Do．we get the Granny Smiths from the fanners' market or the supermarket? Is organic produce healthier for us and the planet?
These are very complex issues that require analysis of many criteria, including the energy used in producing and transporting the food, as well as the type of soil and methods of raising the food．
Despite the complexities, there are some general guidelines you can follow．For instance, eat less meat or eat low on the food chain．Your doctor may have recommended you to restrict your consume red meat because of its too much fat content．Beyond that, there are environmental reasons, too. Raise food animals contributes substantially to climate change because a meat-based diet requires more land, energy and water than a plant - based one．
Drinking plenty of fluids is significant during hot weather or when exercising．But is bottled water the way to go? You may not think so when seeing the true costs．Based on a survey, manufacturing the 30 - plus billion plastic water bottles can produce more than 2．5 million tons of carbon dioxide and use here times the amount of water in the bottle．Adding in transportation, the energy used comes to over 50 million barrels of oil equivalent （等價物）．Consequently, skip the bottled water and drink tap water, both at home and at restaurants．Additionally, bottled water is not necessarily cleaner than tap.
小題1:In Paragraph 2 the author puts forward three questions mainly _____．
A．to prove Americans have less food to choose from

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.
小題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
小題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

  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 (性別) and mental health status (情況) 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 (路徑).
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 (遺傳的) 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.
小題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.
小題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.
小題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
小題4: What is the main problem discussed in this article?
A．Physical well-being. B．Outdoor exercise.
C．Mental illness. D．Harmony with nature.

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(實習醫(yī)師) and residents(住院醫(yī)師) 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(超額) of technological medicine still occur in these institutions.
小題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
小題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
小題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
小題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
