America is a country on the move. In unheard of number, people of all ages are exercising their way to
better health. According to the latest figures, 59 percent of American adults exercise regularly-up 12 percent
from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they
would be more attractive and confident if they were more attractive.
     It is hard not to get the message. The advantage of physical fitness are shown on magazine covers, postage
stamps, and television ads for everything from beauty soaps to travel books. Exercise as a part of daily life did
not catch on until the 1960s when research by military doctors began to show the health benefits of doing
regular physical exercises. Growing publicity for races held in American cities helped increase a strong interest
in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered
equally rewarding-and something safer-forms of exercise, such as walking and swimming, running remains the
most popular form of exercise.
     As the popularity of exercise continues to increase, so does scientific evidence of its health benefits. The
key to fitness is exercising the major muscle group strongly enough to double the heart rate and keep it doubled
for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce
considerable improvements in physical health in about three months.

     Most American kids love Halloween treats, but a bucket of Halloween candy can be a dentist's nightmare.
Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need
to separate the good kinds of treats from the bad.
     It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to
pediatric dentists Dr Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays
in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take
our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The
longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than
candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice.
Hard candies take a long time to consume and are also a bad choice for Halloween treats.
     If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies,
chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the
bacteria in the mouth. But no matter what a child eats, brushing after each meal is still the best way to fight
cavities.

1. What is the main purpose of this passage?

A. To discuss how cavities can be treated.
B. To point out the problems with Halloween celebrations.
C. To tell parents what sweets are less damaging to their children's teeth.
D. To teach parents the meaning of Halloween candies for their children.

2. Why are hard candies especially bad for teeth?

A. They may break the child's teeth.
B. They help bacteria to produce tannins.
C. They contain too much sugar.
D. They stay in the mouth for a long time.

3. According to the passage, which of the following is a better choice for Halloween treats?

A. Chocolate
B. Crackers
C. Raisins
D. Potato chips

4. According to the passage, which of the following is true of tannins?

A. They are produced when the bacteria digest the food.
B. They help to get rid of some bacteria in the mouth.
C. They help chocolate to dissolve more quickly.
D. They destroy the surface of the teeth.

     A small piece of fish each day may keep the heart doctor away. That's the finding of an extensive study of
Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed
(吃) at least an ounce of salt water fish per day than those who never ate fish.
     The Dutch research is one of three human studies that give strong scientific backing to the long-held belief
that eating fish can provide health benefits, particularly to the heart.
     Heart disease is the number-one killer in the United States, with more than 550, 000 deaths occurring from
heart attacks each year. But researchers previously have noticed that the incidence (发生率) of heart disease is
lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example,
among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese,
whose daily fish consumption averages more than 3 ounces.
     During the last two decades, 78% of the men died from heart disease. The fewest deaths were among the
group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship
was true regardless of other factors such as age, high blood pressure, or blood cholesterol (胆固醇) levels.

1. Which of the following is NOT true according to the passage?

A. The Dutch research has proved that eating fish can help to prevent heart disease.
B. There is a low incidence of heart disease in countries like Japan and Greenland.
C. Among all the diseases heart disease is the most dangerous in America.
D. Heart doctors won't call your house so long as you keep eating fish each day.

2. The underlined phrase "this relationship" refers to the connection between _____ and the incidence of heart
    disease.

A. the amount of fish eaten
B. regular fish-eating
C. the kind of fish eaten
D. people of different regions

3. The passage is mainly about _____.

A. the high incidence of heart disease in some countries
B. the changes in people's diet in the United States
C. the daily fish consumption of people in different cultures
D. the effect of fish-eating regularly on people's health

4. Why is heart disease the most dangerous killer in the United States?

A. The author doesn't give a definite answer.
B. Because American people drink too much spirits.
C. Because there are a great number of fat people there.
D. Because American people eat too much fatty fish.

5. How many lives could probably be saved each year in the United States by eating fish according to the
    Dutch study?

A. 550, 000.
B. 110,000.
C. 275,000.
D. 852.

     A picture, a calendar or even a balloon may be the best way for millions of people living in China's vast
country areas to learn about AIDS, one of the biggest threats to public health in the world today.
     China has decided to use user-friendly methods including exhibitions, VCDs and TV programmes to
spread knowledge of the disease across the nation to try to keep it in check.
     Educating people nationwide about AIDS is the top priority (优先权) to prevent the disease from getting
out of hand. The farmers will be given knowledge in the easiest way that they can understand.
     A recent survey from the commission (调查团) of more than 7,000 people in China showed that nearly
20 percent of them had never heard of AIDS before. Just over 71 percent said they knew AIDS was highly
infectious (传染), but most of them had no clear idea of how the disease could be spread. Just over 62
percent said they knew they could do things in advance to prevent them catching AIDS but they didn't know
what these measures were.
     The month-long survey, carried out last December, talked to people in seven countries and cities across
China including both developed coastal areas and less-developed inland areas. The interviewees changed from
15 to 49 years old, and country residents were about 63% of the total surveyed.
     Chinese residents, especially those in the country, have very little knowledge about what AIDS is all about,
not to mention prevention and treatment. By the end of last year, there were 22,517 known HIV\AIDS cases
in China. However, more than 6,000,000 people in China have been infected.
     Since 1985, China has discovered 880 patients with AIDS-466 of them have died. Sharing needles,
prostitution (卖淫) and contaminated blood transfusions are major ways for HIV to spread. A lack of education
has been the biggest difficulty against nationwide efforts to prevent AIDS, especially in the countryside.

1. The author's purpose in writing the passage is to _____.

A. show his concern about the health of people
B. make people know about AIDS
C. call on people to fight against AIDS
D. tell us people are short of the knowledge of AIDS

2. The greatest difficulty against the nationwide effort to prevent AIDS lies in _____.

A. misunderstanding of people
B. the shortage of money
C. its infection
D. lack of education

3. It is judged that there are _____ people hit by AIDS in China at present.

A. 22,000
B. over 6,000,000
C. 880
D. over 7,000

     Jim suffered heart problems. In conversation he expressed little joy and it seemed that his life was
drawing to a close.
     When his heart problems led to operation, Jim went through it successfully, and a full recovery was
expected. Within days, however, his heart was not beating properly. Jim was rushed back to operation,
but nothing was found to explain the cause of his illness. He died on the operating table on the day before
his 48th birthday.
     Dr. Bruce Smoller, a psychologist, had had many conversations with him, and the more he learned, the
stranger he realized Jim's case was. When Jim was a child, his father, a teacher, suffered a heart attack and
stayed home to recover. One morning Jim asked his father to look over his homework, promising to come
home from school at noon to pick it up. His father agreed, but when Jim returned his father had died. Jim's
father was 48.
     "I think all his life Jim believed he killed his father," Dr. Smoller says. "He felt that if he had not asked him
to look at his homework, his father would have lived. Jim had been troubled by the idea. The operation was
the trial (判决) he had expected for forty years." Smoller believes that Jim willed himself not to live to the age
of 48.
     Jim's case shows the powerful role that attitude plays in physical health, and that childhood experiences
produce far-reaching effect on the health of grown-ups. Although most cases are less direct than Jim's,
studies show that childhood events, besides genes, may well cause such midlife diseases as cancer, heart
disease and mental illness.

1. Jim was sent back to operation because _____.

A. his heart didn't work well

D. Jim's death is closely connected with his father's.

3. From Smoller's words, we can infer that _____.

A. Jim's father cared little about his study
B. Smoller agreed that Jim did kill his father
C. Jim thought he would be punished some day
D. Smoller believed Jim wouldn't live to the age of 48

4. Which of the following could have strong effect on one's physical health according to the text?
    a. One's genes.

     With big handbags becoming a key fashion accessory (配饰) for working women, health experts are
warning they can also become a key health concern. 
     Bags for women have become bigger and heavier as designers combine briefcases with handbags and
straps have become longer, resulting in many users complaining of neck, shoulder and back problems. 
     "I see so many women with neck pains and headaches and what I usually do is look for their purse and
pick it up," said Jane Sadler, a family practice physician at Baylor Medical Center in Garland, Texas. "We
take it over to the scale and weigh it and usually they're anywhere from 7 to 10 pounds. We're really going
to see women with more and more problems later on if we continue the big purse craze." 
     William Case, a physical therapist (临床医生) in private practice in Houston, Texas, urged designers "to
place a cute, educational caution tag (标签) on all bags to inform buyers of potential neck and shoulder
dangers." Above all, he suggested correct posture while carrying big purses, keeping the head and shoulders
upright. Patients should also often change the size and weight of purses carried. 
     "The extra-large purses are quite extraordinary. They look beautiful when the women wear them, but I
don't know how aware they are of the potential problems," Case said.
     Placing objects on one shoulder was one of the least efficient (高效率的) ways of carrying a load,
according to a professor from Cornell University in New York State. "This causes a great imbalance," he said.
"If a big bag is a fashion accessory, then occasional and symbolic use is fine. If not, then keep it light."

1. Jane Salder would"look for their purse and pick it up"in order to see whether the purses _____.

A. contained enough

     Running, as most of you already know, is a sport that all sorts of people love. Running a marathon is also
something that many long-distance runners have as a goal. Now if you decide you want to train for a marathon,
how do you go about getting yourself into excellent shape for the race of your life? 
     Most marathon training schedules last around 20 weeks and are designed for runners who can run 4-5 days
per week. The secret of a successful training schedule lies in avoiding injury that can happen through pushing
yourself too fast or too hard. So, the idea is to increase your mileage gradually from, let's say,20 miles per week
up to runs of 50 miles per week at some point before the actual marathon. Alternate (交替) hard days with easy
days: an easy day could be a day off altogether or something else like a three-mile run which, although it might
not seem to be really worth the effort to some of you, actually is a joy to do.
     Be careful how you warm up and slow down, because these are the times when injuries could happen. When
you set off for a run, take the first mile slowly and when you break into a sweat, stop and do some stretching
exercises for a couple of minutes. Always take the last mile slowly too-if you stop suddenly after a hard run,
then those of you who might have heart attacks are putting yourselves at greater risk at the point. One word of
warning: don't start a training schedule without some guidance from a properly qualified trainer. He or she will
be able to tell you what you're doing right or wrong! Remember that under normal circumstances, health
benefits from regular running are an increased sense of energy and well being, together with fitness.

     In the past industries had more freedom than they have now, and they did not need to be as careful as
they must today. They did not need to worry a lot about the safety of the new products that they developed.
They did not have to pay much attention to the health and safety of the people who worked for them. Often
new products were dangerous for the people who used them; often conditions in the work place had very
bad effects on the health of the workers.
     Of course sometimes there were real disasters which attracted the attention of governments and which
showed need for changes. Also scientists who were doing research into the health of workers sometimes
produced information which governments could not ignore. At such times, there were inquiries into the
causes of the disaster or the problems. New safety rules were often introduced as a result of these inquiries;
however,the new rules came too late to protect the people who had died or become seriously ill.
     Today many governments have special departments which protect customers and workers. In the U.S.,
for example, there is a department which tests new airplanes and gives warnings about possible problems.
It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs
that companies sell. A third department looks at the places where people work, and then reports any
companies that are breaking laws which protect the health and safety of workers.

1. According to Paragraph 1, compared with today, industries in the past _____. 

A. were controlled less strictly
B. were worse off
C. affected more people's health
D. put out more unhealthy products.

2. It is implied in Paragraph 2 that years ago governments _____.

A. paid much attention to the results of scientific discoveries
B. seldom introduced safety laws before disasters occurred
C. hardly ever looked into the causes of tragedies
D. imposed safety rules as soon as disasters occurred

3. The main topic of the passage is _____.

A. industries in the past and at present
B. changes in the development of industries
C. the protection of industrial workers and customers
D. the freedom of industries

4. The purpose of this passage is to _____.

A. inform
B. criticize

     The gray-haired lady can't wait to leave the building to search for her dad. Unless watched, she will walk
in the streets in an effort to find her father, who died 30 years ago.
     Not all cases of Alzheimer's disease look like this, but Alzheimer's is a serious disease that is said to be the
fourth or fifth leading cause of death for people over age 75.
     It is said that about three percent of the U.S. population over age 65 have Alzheimer's. In the early stages,
people may exhibit short term memory loss. Some may experience changes in personality, easy to be angry.
As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all.
This progressive disease generally lasts 8 to 10 years before death occurs.  
     While no one is certain what causes these changes in the brain's nerve fibers, their effect is certain.
Alzheimer's destroys not only the patients, but also spouses (配偶), friends and families.
     What should you do if you notice progressive memory loss in yourself or a loved one? Have the person
examined by a doctor who is a specialist in the treatment of Alzheimer's disease.
     Though many reasons other than Alzheimer's disease may cause memory loss, its early diagnosis (诊断)
and treatment may delay some of the most serious effects.
     What feeling will you likely experience should a loved one suffer from Alzheimer's disease? A person will
often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease,
you may experience hurt and disappointment when he or she doesn't remember you are married.
     Life for the Alzheimer's patients and their loved ones will never be the same as the disease progresses,
bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them
honestly will serve one better than burying them.

     "Just five more minutes." "I'm tired!" "I can't get up." If you have ever had trouble getting up in the
morning, you are not alone. Many kids in the United States do not get enough sleep.
     Your body needs sleep-and lots of it! "Evidence (证据) shows that elementary-age children need at
least nine hours of sleep per night," said sleep expert Dr. Carl Hunt.
     Kids who do not sleep enough cannot do their best, experts say. A tired kid may be moody and act
badly. Being tired can also cause kids to forget things, have trouble learning, and have trouble playing
sports.
     Not sleeping enough can also affect kids' safety. Experts say children who are tired are more likely
to suffer injuries.
     Lots of kids lose sleep because they are busy. Many take part in after-school activities. Then they
go home, eat dinner, and do homework. Afterward, many kids watch TV, play video games, and surf
the Internet. That leaves less time for sleep.
     Sometimes you may not be able to go to bed early. But, if you get a choice whether to stay up late,
think twice. A good night's sleep can help you feel your best!
