We humans love to scare ourselves. Newspapers and TV news are full of shock-horror stories about the killer flu virus(流感病毒)but are there things we can do to cut our risk of catching it?
Every year, people in Britain catch the flu virus and some of those who are already ill, or are very young, may die. It is very sad, but modern treatment means that many deaths can be avoided.
Experts tell us that the world is another flu epidemic(流行)and that the latest bird-flu virus would be the most likely cause. Humans can catch the disease only after closely contacting with a sick bird. However, if someone who had normal flu was to come into contact with bird flu, this could be very dangerous. The bird flu virus could attach(附在)itself to the human flu virus, mutate and then start to spread from person to person.
Coughs and sneezes(打噴嚏)always have spread diseases, especially colds and flu, and they still do. If bird flu does begin to infect humans, it will spread through coughs and sneezes.
If you want to stay free of flu and someone coughs or sneezes at you, what should you do?
First, keep your hands away from your face and wash them and your face as soon as you can. If a cough or a sneeze spray misses your face and you accidentally touch a droplet with your hands and then touch your face, the flu or cold bug could creep into your system.
【小題1】The chances of most people catching bird flu are very small because __________.

A．they are strong enough to resist the infection 
B．only after closely contacting a sick bird can they be infected 
C．bird flu does not happen very often in the world

【小題3】If a man with common flu is infected with bird flu, __________.
A．there must be no cure for him

C．he must feel cold 
D．he is likely to die

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 (營養(yǎng)) 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 (蛋白質(zhì)) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (維他命) 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 (人的個(gè)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 (壽命).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.

The World Health Organization and several other United Nations agencies are calling for a major new effort to fight malaria, tuberculosis and AIDS. These three infectious diseases killed almost 6 million people last year. That is about 10 percent of the total number of deaths around the world last year.
The WHO and UN agencies released a new report at the World Economic Forum in New York City earlier this month. The document says that deaths around the world from malaria and tuberculosis could be cut in half by the year 2010. It also says the number of deaths from AIDS could be reduced 25 percent within that same time period.
The report is called “Calling Up the Response to Infectious Diseases.” It calls for huge new investments in methods to prevent and treat infectious diseases. Officials say money is needed for research and to purchase drugs. Money is also needed to devices to prevent diseases, such as bed nets. Bed nets prevent mosquitoes that carry malaria from biting people while they sleep.
David Heymann, director of the infectious disease program at the World Health Organization, says that providing effective drug treatments is important for improving peoples’ health and economic well – being. Reducing disease can also help improve economic growth in developing countries.
The WHO report also describes successful health programs in developing countries. In Peru, for example, the number of tuberculosis cases was cut in half by increasing the treatment to control the disease. In Vietnam, malaria was reduced 97 percent through the use of bed nets. And in Uganda, cases of the virus that causes AIDS were cut in half among pregnant women and children through the use of anti – AIDS drugs.
This new international health campaign is estimated to cost about 12,000 million dollars a year. So far, officials say the campaign has about 2,000 million dollars. The WHO says the campaign will need stronger relationships among government, private aid agencies, and drug companies to succeed.
【小題1】According to the report         is the disease most difficult to fight.

A．malaria B．tuberculosis C．AIDS D．influenza
【小題2】To prevent these diseases, a large amount of money is needed to          .
A．to buy food and pay for the caretakers
B．do research work, buy drugs and devices

【小題3】We can infer from the text that reducing infectious diseases is          .
A．to help the countries develop better
B．to promote cooperation between countries
C．to help people get more scientific knowledge
D．to help people get a cleaner environment
【小題4】Most serious infectious diseases spread mainly in         .

Britons Learn to Forgive
LEEDS, England—A Leeds University psychology(心理學(xué)) professor is teaching a course to help dozens of Britons forgive their enemies.
“The hatred (仇恨) we hold within us is a cancer,” Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.
More than 70 people have become members in Hart’s first 20-week workshop in London—a course he says is the first of its kind in the world.
These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian-born Hart.
The students meet in groups of eight to ten for a two-hour workshop with an adviser every fortnight.
The course ending in July, is expected to get rid of the cancer of hate in these people. “People have lots of negative attitudes towards forgiveness,” he said. “People confuse（混淆） forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one.” Hart and his team have created instructions to provide the training needed.
“The main idea is to give you guidelines on how to look at various kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with, ”said Norman Claringbull, a senior expert on the forgiveness project.
Hart said he believes forgiveness is a skill that can be taught, as these people “want to get free of the past”.
【小題1】From this passage we know that      .

A．high blood pressure and heart disease are caused by hatred
B．high blood pressure can only be cured by psychology professors
C．without hatred, people will have less trouble connected with blood and heart
D．people who suffer from blood pressure and heart disease must have many enemies
【小題2】In Hart’s first 20-week workshop, people there can      .
A．meet their enemies
B．change their minds
C．enjoy the professor’s speech
D．learn how to quarrel with others
【小題3】If you are a member in Hart’s workshop, you’ll      .
A．pay much money to Hart
B．go to the workshop every night
C．a(chǎn)ttend a gathering every fortnight
D．pour out everything stored in your mind
【小題4】The author wrote this passage in order to      .
A．persuade us to go to Hart’s workshop
B．tell us the news about Hart’s workshop
C．tell us how to run a workshop like Hart’s
D．help us to look at various kinds of angers

Below are some smart ways to stay healthy suggested by some American experts.

Drink More Coffee
When was the last time you heard a doctor use the word miracle? Well, wake up and smell the coffee: “It’s amazing,” says liver specialist Sanjiv Chopra, MD, professor of medicine at Harvard Medical School. “Coffee is truly a lifesaving miracle drug.”
Though he says it’s still a “scientific mystery” how a simple cup of coffee works its wonders in the body, large epidemiological studies have repeatedly proved its astonishing benefits.
“Drink it black, or at most put a little skim milk in it” to minimize calories, Dr. Chopra recommends. He drinks at least four cups a day himself, though most people should limit themselves to two. And no, he jokes, “I’m not sponsored by Starbucks.”
Take a Walk for Your Memory
Aerobic (有氧運(yùn)動(dòng)的) exercise is good for your body, great for your mind, according to the latest research from brain-fitness pioneer Arthur Kramer. Every year, an area called the hippocampus, which is key to memory, shrinks by about 1 to 2 percent, increasing the risk of dementia (腦衰) as the years roll by. However, Kramer’s new investigations reveal that the hippocampi of adults who walked briskly for about 45 minutes three times a week grew by about 2 percent over the course of a year, preventing age-related shrinking.
It’s never too late to start exercising, Kramer says; volunteers in his research were between 55 and 80 years old and hadn’t exercised at all. And it doesn’t need to be backbreaking. “Anything that raises your heart rate seems to work,” he says. “Walking is fine. Just find something you like and do it.”
Early to Bed, Early to Eat
“Being a night owl might increase your waistline,” says sleep expert Michael Breus, PhD. People who stay up late and sleep late tend to eat more fast food and consume more of their calories after 8 p.m. than do normal sleepers.
“One of the easiest things that anyone on a diet can do to improve her results is go to bed and wake up at the same times every day,” Breus says. “This way, your body knows when to sleep and is much more efficient. Organize your eating, too, by trying to eat meals at the same times every day. Avoid eating after 8 p.m., and don’t miss morning meals by sleeping in.”
Use the 20-Second Rule
What’s the difference between having a goal and actually accomplishing it? Just 20 seconds, says positive-psychology specialist Shawn Achor. Researchers have learned that if we can cut 20 seconds off the startup time required for a task, we’re much more likely to follow through. So, for example, if you want to work out in the morning, place your shoes and exercise clothes next to your bed the night before. If you want to praise people more, put thank-you notes and a pen on your desk.
Imagine the Worst to Feel Better
Don’t count your blessings; subtract (扣除) them. “Consciously spend a few minutes imagining what your life would be like without the good things,” says Timothy Wilson, a psychologist at the University of Virginia. You’ll experience stronger feelings of love, gratitude, and happiness when you think about what life would be like without the people and things you love. “And they’ll seem surprising and special again,” he adds.
【小題1】 According to Sanjiv Chopra, most people should not drink more than ______ cups of coffee a day.
A．twoB．threeC．fourD．six
【小題2】Which of the following may help people on a diet to improve their results?
A．Raising their heart rate.B．Taking a walk for their memory.
C．Eating at fixed times.D．Sleeping in every morning.
【小題3】According to Shawn Achor, if people place their shoes and exercise clothes next to their bed at bedtime, they’re more likely to ______ the next morning.
A．do exerciseB．set a goal
C．cut 20 seconds offD．sleep 20 minutes more
【小題4】 Why should people spend a little time imagining their life without good things?
A．To experience surprise.B．To feel better.
C．To consider their own blessings.D．To prepare for the worst.

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: 10% fewer heart attacks, 8% fewer strokes, 4% fewer deaths, 11% fewer new cases of heart disease, and 240 billion dollars in health care savings.
Researchers found it could prevent 100,000 heart attacks and 92,000 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California, San Francisco 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（鈉）, which is how foods may list their salt content.
The government says the average American man ears 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 rise. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference.
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 show that the calorie information on the menu can influence what parents order for their children.
【小題1】According to the passage, what disease is not related to salt in diet?

A．Cancer.B．Stroke. C．Blood pressure.D．Heart attack.
【小題2】It can be inferred from the passage that________.
A．a(chǎn)ll the heart diseases result from eating too much salt
B．the American Heart association suggest less than 3 grams of salt a day for everyone
C．how much salt is contained in certain food is measured by the amount of sodium
D．the less salt one eats, the healthier he will be
【小題3】The National Salt Reduction Initiative aims to________.
A．a(chǎn)ttract the public attention to the problem
B．require fast food places to list salt information
C．inform people of the harm that salt does to health
D．put pressure on food companies and restaurants
【小題4】The last paragraph mainly tells us________.
A．Bloomberg has made some other efforts to improve people’s health
B．Bloomberg is very successful in his career
C．parents must pay great attention to calorie information
D．a(chǎn) new study is being done about calorie information
