The key to reaching or staying at a healthy weight is regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing complicated exercises or going to the gym (體育館) every day. All that matters is that each week you get the right balance of activity, including aerobic (有氧健身法的) strength building, and flexibility (柔韌性) exercise. Make exercise a habit by scheduling some every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day of activity seems like a lot of time. The good news is that it’s OK to divide it into shorter “exercise breaks” throughout the day. Just as you might have a healthy snack to stop yourself getting hungry, exercise snacks can keep energy level high. So get up 15 minutes earlier and do some yoga or other stretching (伸展) activity. Fast walk or jog (慢跑) for 15 minutes at lunch. Do the same thing after school ­­­­­or walk or bike home. Add to that taking the stairs, gym class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
Here are 5 simple ways to make an exercise lifestyle change:
1. Start today. Go outside for a walk.
2. Take the stairs instead of the elevator.
3. Instead of driving, walk or bike to places like school or a friend’s house.
4. Clean your room or wash the car.
5. Limit your time watching TV, using the computer, or playing video games--and when you do play, try some games that get you moving.
小題1: The underlined phrase “exercise snacks” in the second paragraph probably means ________.
A.food eaten before exercise
B.food eaten during exercise
C.shorter “exercise breaks”
D.a(chǎn) new kind of exercise
小題2:Why should we have exercise snacks every day?
A.Because they can stop us getting hungry
B.Because they can keep energy level high
C.Because they can include many kinds of sports
D.Because they are more likely to relate to our daily life
小題3:Which of the following is NOT mentioned in the passage?
A.To go hiking on your holidays

    Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu(流感), and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses - flu A, B and C. There is no cure for either illness , but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities , there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome(綜合癥) ,a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
 
小題1: According to the author, knowing the cause of the misery will help ________.
A.shorten the duration of the illness
B.the patient buy medicine over the counter
C.the patient obtain cheaper prescription drugs
D.prevent people from catching colds and the flu
小題2: We learn from the passage that ___________.
A.one doesn’t need to take any medicine if he has a cold or the flu
B.a(chǎn)spirin should not be included in over-the-counter medicines for the flu
C.delayed treatment of the flu will harm the liver and central nervous system
D.over-the-counter drugs can be taken to ease the misery caused by a cold or the flu
小題3: According to the passage, to combat the flu effectively, ___________.
A.one should identify the virus which causes it
B.one should consult a doctor as soon as possible
C.one should take medicine upon catching the disease
D.one should remain alert when the disease is spreading
小題4:Which of the following symptoms will distinguish the flu from a cold?
A.A stuffy nose.   B.A high temperature.
C.A sore throat.  D.A dry cough.
小題5: If children have flu-like symptoms, their parents _______________.
A.a(chǎn)re advised not to give them aspirin
B.should watch out for signs of Reye syndrome
C.a(chǎn)re encouraged to take them to hospital for vaccination
D.should prevent them from mixing with people running a fever

If you want to increase your vocabulary, the best way to do it might be to pick up a guitar, or learn the violin. A new study shows that learning to play a musical instrument makes the brain more able to remember words.
“Grown-ups with music training in their childhood can have better memory for words,” said Dr Agnes Chan of the Chinese University of Hong Kong, who did the research. “They can remember things that you tell them better than those who did not have music training when they were young.”
It seems that one can remember spoken words because his brain has a special part. “That part of the brain is larger in musicians than in non-musicians,” Dr Chan told BBC. “If that part of the brain is larger, it may be better developed and so this explains very nicely our results.”
Dr Chan and her workmates came to their conclusion after studying students. Their research is reported in the latest edition of the journal(雜志) Nature. “We did the experiment with 60 girl college students from our university and 30 of them have at least six years training with one western musical instrument (such as the violin and the piano) before the age of 12. The other 30 had received no music training. We tested their memory by reading them some words and asking them to remember these words—a very common test for memory. We found that people who have had music training can remember about 70% more information than those who have not had any music training.”
Dr Chan thinks the process(過(guò)程) of learning is more important than the actual instrument used. She also believes if one is able to remember words through learning to play instruments, he or she could have some very real benefits. Dr Chan thinks this could be developed into a medical way for patients who are suffering from memory loss.
小題1: According to the writer, learning to play a musical instrument helps to ______.
A.get more knowledge
B.live more happily
C.remember more words
D.make one become a musician
小題2:Which of the following is true according to the passage?
A.Dr Chan thinks people should have music training when they grow up.
B.Dr Chan thinks the special part of the brain doesn’t need developing.
C.Dr Chan thinks people should have music training when they are young.
D.Dr Chan thinks musicians have a larger brain than non-musicians.
小題3:How many students took part in Dr Chan’s research?
A.30 girl students.B.60 girl students.
C.17% of his students.D.60 girl and boy students.

Too cold for recess?  School policies vary as much as temps
When is it too cold for schoolchildren to go outside for recess(課間休息)? The answer varies widely based on where a school is located and what the kids are used to.
Consider:  One northern Minnesota school says it has to be 15 below zero before kids are kept inside. But in areas along the East Coast, temperatures below 35 to 40 degrees could keep kids inside. Canceling recess because of the cold is no small issue considering that much of the USA is trembling through what may be its coldest winter in a generation, according to AccuWeather.
There is no national temperature standard for when to keep kids inside during the winter months, the U.S. Department of Education says. Decisions are made at the local level, either by principals or school districts.
Consequently, policies are all over the map:
? In International Falls, Minn., the self-described "Icebox of the Nation," where the average high temperature in January is 13 degrees, Falls Elementary School Principal Jerry Hilfer says, "if it's 15 below (or warmer), they go out, no matter what." "At 20 below, it gets iffy," he adds.
? In Wicomico County, Md., principals typically keep children indoors when temperatures drop below freezing, or if it's raining or snowing, says Susan Jones, the school system's director of elementary education.
"That's the bottom line," says Curtis Twilley, principal of Pemberton Elementary School in Salisbury, Md. Twilley says students get little exercise when recess stays indoors. At Pemberton Elementary, the students will typically play board games or computer games in a classroom because the school's gym is occupied with other classes, he says.
? For schools in Marquette, Mich., which averages about 12 feet of snow per season, school officials acknowledge students are probably a little more prepared than those in some more mild climates.
小題1:Which of the following is not true according to the passage_________.
A.No national temperature standard is made for when to keep kids inside during the winter months.
B.Susan Jones insists students get little exercise when recess stays indoors.
C.In Wicomico County, children are kept indoors when temperatures dip below freezing.
D.Mich has about 12 feet of snow per season on average.
小題2: Which place calls itself Box of Ice?
Wicomico County  B. Marquette    C.Salisbury       D. Minn
小題3: Considering_______, canceling recess In USA because of the cold is a big issue.
A.different schools have different principles.
B.much of the USA has very cold winter.
C.physical activity can boost student performance.
D.decisions are made at the local level,
小題4: The underlined word iffy means _______.
A.uncertain B.surprisingC. seriousD.worse
小題5: What will be talked about next?
A.More school policies
B.The reasons why school policies vary.
C.Measures to improve the situation.
D.Necessities to improve the situation

Alzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it.
Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.
There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients.
Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.
The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years.
Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition.
Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future.

To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount.That is according to a study published this Monday in the Public Library of Science Medicine Journal.
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't.
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council.“The benefit was also seen regardless of whether or not people were fat and what social class they came from.”
Study participants(參與者)scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake.
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes.But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years.
“We can't say that any person could gain 14 years by doing these things, ”said Dr.Tim Armstrong, a physical activity expert at the World Health Organization.“The 14 years is an average across the population of what's theoretically(理論上地)possible.”
“Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said.“We need to work on providing people with much more practical support to help them change.”
小題1:Which of the following DOESN'T belong to the four healthy habits?
A.Eat five servings of fruits and vegetables a day.
B.Do proper exercise in the morning every day.
C.Drinking alcohol in the proper amount every day.
D.Having a cigarette before going to bed every day.
小題2:We can learn from the passage that            
A.Susan Jebb did not take part in the study.
B.the study observed people as well as tested specific changes.
C.there's no need for people under 45 to adopt these good habits.
D.only those from first class can benefit from these healthy behaviors.
小題3:What can be inferred from the passage?
A.All the people are well aware of the harm of their bad habits.
B.People aged 45 to 70 have bad habits in the United Kingdom.
C.Governments should take measures to help people change their bad habits.
D.People have adopted the four healthy habits after knowing they're good.
小題4:What would be the best title for this passage?
A.Smoking and Drinking Cuts You 14 Years
B.How to Live a Much Healthier Life
C.Healthy Habits May Give Extra 14 Years
D.How to Make Your Life Longer Than Others

Think about what you had for lunch: Was it a hamburger? A chicken sandwich? Barbecue? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet?
It can—in a big way. New studies show how food and its production affect the globe and its warming climate. You’ve probably heard of global warming : The temperature is on the rise because humankind has been releasing (排放) amounts of gases into the atmosphere. One of these greenhouse gases is carbon dioxide(二氧化碳).
What does this have to do with food ? A big part of the carbon dioxide that we put in the atmosphere every year comes from the process of making and eating food. The production of meat contributes a lot of that carbon diode. And much of meat’s contribution comes from beef , which is responsible for releasing even more warming gases into the atmosphere.
The process of making a hamburger ,for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow waste is a major source of methane (沼氣) — an especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed (加工) and shipped to a shop, which takes fuel . Most of the cow won’t even be used for meat that people eat. By the time a hamburger finally lands on a dinner plate, it has made a heavy effect on the environment.
We can reduce the production of global-warming gases by eating less beef .Other kinds of meat like pork and chicken do less harm to the environment—at least in terms of the amount of greenhouse gases released. 
All kinds of meat are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide into the air. So changing our diet to less meat and more vegetables, as it turns out, may do the world some good.

In terms of history, Australian cuisine(烹飪)was on the basis of traditional British cooking brought to the country by the first settlers.Modern Australian cuisine,however.has been heavily influenced by Australia’ s Asian and Southeast Asian neighbors.The trend,encouraged by long-term government health programs,is towards low-fat healthy cookery including low-fat meat and lightly cooked,colorful,steamed or fried vegetables.Besides,1ike many English families,in many Australian homes,a widespread tradition of having roast turkey,chicken,and ham for Christmas 1unch or dinner still remains.
Generally breakfast is light in most parts of Australia.but in the colder regions porridge or meals similar to the full English breakfast may be consumed.In recent years,however,most Australian people prefer light breakfast in order to control their weight.The 1ight breakfast commonly consists of cereals(谷類),toast and fruit.A heavier breakfast will frequently include fried bacon,eggs,mushrooms,etc.Drinks taken at breakfast include tea,coffee,milk or juice.
The evening meal is the main meal of the day for most Australians,and when consumed at home,it is often eaten with members of the immediate family.The dishes served will vary widely according to the tastes and background of the family.A typical Australian restaurant might offer sandwiches,chicken or other meat-based dishes and cakes.

A super drug that could remove Alzheimer’s (老年癡呆癥),heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(膽固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遺傳傾向), lifestyles and life events. Many genes are probably involved.
小題1:Some people are able to live to 100 years because of ______.
A.a(chǎn) magical medicineB.three special genesC.good living habitsD.longevity proteins
小題2:Why does the discovery of the longevity genes mean a lot?
A.Because it can bring great benefits to scientific labs.
B.Because it can help people change their unhealthy genes
C.Because it helps produce a drug that can make people live longer.
D.Because it will help scientists build up a new branch of biology.
小題3: From Paragraph 4 we can infer that ________.
A.longevity genes can create good cholesterol.
B.the volunteers share some common ancestors
C.bad habits are likely to have no effect on the volunteers
D.longevity genes protect the volunteers against bad habits
小題4:What is Andrew Ketteringham’s attitude toward the study?
A.PositiveB.NegativeC.CriticalD.Cautious
