found in the African rain forest suddenly turns up in children in the American Midwest. It"s hard not to wonder
of the disease that comes from foreign animals is homing in on human beings. "Most of the infections (感染)
we think of as human infections started in other animals." says Stephen Morse, director of the Center for Public
Health Preparedness at Columbia University.
It"s not just that we"re going to where the animals are; we"re also bringing them closer to us. Popular foreign
pets have brought a whole new disease to this country. A strange illness killed Isaksen"s pets and she now thinks
that keeping foreign pets is a bad idea. "I don"t think it"s fair to have them as pets when we have such a limited
knowledge of them." says Isaksen.
"Laws allowing these animals to be brought in from deep forest areas without stricter control need changing."
says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their
owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But it may
develop into something harmful (有害的). Monkey-pox doesn"t look a major infectious disease. But it is not
impossible to pass the disease from person to person.
B. prevent us from being infected
C. enjoy being with children
D. suffer from monkey-pox
B. We need to study native animals.
C. They can"t live out of the rain forest.
D. We do not know much about them yet.
B. a clear warning
C. a dangerous animal
D. a morning call
B. may easily get infected by diseases from dogs
C. should not be allowed to have pets
D. should stop buying pests from Africa

elementary school years, she was thin, but things changed as she grew up.
"My bad eating habits began during my kid years," says Healther Daivs. "In middle school, I played sports,
but with a diet of hamburgers and soda for lunch...big family dinners...I became overweight." During her
senior year in high school, Heather Davis, who is 5 feet 9 inches tall, weighed 200 pounds. "We had a meat-
and-potatoes family. We had dessert every night and I was a member of the "clean your plate club". I tried my
best to stop gaining weight, but it seemed impossible." remembers Healther Daivs. "It caught up with me." By
the time she was 21 and attended college, Heather Davis" weight had increased to 250 pounds. Heather Davis
says it was caused by emotional eating, a junk-food diet and lack (缺少) of exercise.
The realization that failed diet led to the physical (身体的) cost of obesity (肥胖) made her decide to lose
weight by taking exercise. She did gym exercise for two weeks and began changing her diet by cutting out
potato chips, ice cream and pizza. Within the first two weeks, she had lost 18 pounds. Heather Davis remained
determined, and over the next 12 months, with the support of her family and regular training with a gym trainer,
she lost 110 pounds.
"My days of treating my body badly are over," say Heather Davis. "I focus on things I enjoy such as
European trins, language classes and beach vacations." She says even though she"s lost 110 pounds, she"s still
the same person-outgoing, and more importantly-happy. She"s also become a good example for those who also
want to lose weight. "If I can do it, anybody can do it," says Heather Davis.
B. when she was 22 years old.
C. When she was a teenager.
D. During her college years.
B. it happened though I tried to prevent it
C. it kept up with me
D. it had a bad effect on my daily life
B. she ate more when she was stressed
C. she used to have a junk-food diet
D. she seldom took part in sports
B. How to lose weight
C. Stay away from unhealthy diets
D. Heather Davis-an outgoing woman.

About 300 BC, an Indian writer described forests that were somewhat like national parks today. The killing
of game animals was carefully governed. Some animals were fully protected. Within the forest, nobody was
allowed to cut trees, burn woods, or trap animals for their furs. Animals that became dangerous to human
visitors were trapped or killed outside the park so that other animals would not become uneasy.
The need for wildlife protection is greater now than ever before. About a thousand sorts of animals are in
danger of extinction, and the speed at which they are being destroyed has been putting on. With mammals, for
example, the speed of extinction is now about one sort every year; from AD l to 1800, the speed was about one
sort every fifty years. Everywhere, men are trying to solve the problem of saving wildlife while caring for the
world"s growing population.
B. was described by an Indian writer about 300 years ago
C. is met in many countries today

D. no killing of animals was allowed

C. the trees in the forests
D. the needs of people
B. about a thousand sorts of mammals are in danger of extinction
C. the speed of extinction of" mammals is lower now than it was from AD l to 1800
D. hunters who kill endangered sorts of animals are seriously punished by law
B. dying out
C. growing up
D. going away
entertainment purposes-is fair and respectful? Zoo officials say they are concerned about animals. However,
most zoos remain "collection" of interesting "things" rather than protective habitats (栖息地).
Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.
Zoos claim to educate people and save endangered species, but visitors leave zoos without having leamed
anything meaningful about the animals" natural behavior, intelligence, or beauty. Zoos keep animals in small
spaces or cages, and most signs only mention the species" name, diet, and natural range.
The animals" normal behavior is seldom noticed because zoos don"t usually take care of the animals" natural
needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and
physical exercise. This results in unusual and self-destructive behavior called zoochosis. A world-wide study
of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed
that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears
spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.
Furthermore, most animals in zoos are not endangered. Captive breeding (圈养繁殖) of endangered big
cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot
about their captive breeding programs because they do not want people to worry about a species (物种) dying
out. In fact, baby animals also attract a lot of paying customers. Haven"t we seen enough competitions to name
baby animals?
Actually, we will save endangered species only if we save their habitats and put an end to the reasons people
kill them. Instead of supporting zoos, we should support groups that work to protect animals" natural habitats.
B. Unhappy.
C. Natural.
D. Simple.

B. Zoos fail in their attempt to save animals.
C. Zoos should treat animals as human beings.
D. Zoos use animals as a means of entertainment.
B. giving examples of animals in the wild
C. questioning the way animals live
D. discussing the advantages of natural habitats
B. most animals in zoos are endangered species
C. some endangered animals are reproduced in zoos
D. it"s acceptable to keep animals away from their habitats
the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight
hours are enough for the health of grown-ups. Some can do with less than this amount,but others may need
more. Every person knows his own need. It is then a matter of good judgement to satisfy his need. Sleep
should always be enough to make one bring back his strength and get ready for a day"s work.
Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable
to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body the
most complete relaxation (松弛).
Ability (能力) to sleep is large lay habit. The conditions re- ferred to only lead to sleep. Out-of-door
exercises, a good habit of regular hours and the avoidance (避免) of late eating and worry, which are largely
within the control of any person, are all helpful to sound sleep.
A bath at bedtime, neither hot nor cool but of body temperature, may be helpful to sleep. Sleep-producing
drug (药) should never be taken except when suggested by a doctor.
B. No more than eight hours.
C. Eight hours or so.
D. No less than eight hours.
B. Fast sleep.
C. Complete sleep.
D. Sleep without any sound.
B. Staying up late at night.
C. Eating something at bedtime.
D. Forming the habit of taking sleep-producing drug.

C. his weigh
D. his character
B. do any housework

slowly for long distances become so popular? Most joggers begin because they hear it is a very good exercise.
Jogging makes the heart stronger and helps people lose weight. It can also help them feel better about
themselves.
Donald Robbins, who is forty-two years old and works in an office, began jogging a few years ago
because he felt he was too fat. At first he could only run about 100 yards. It took him three months to be
able to run a mile. But two years later, he ran in a marathon race over twenty-six miles. Many joggers, like
Donald Robbins, feel that if they can succeed at jogging, they can succeed at other things also, and quite often
this feeling helps them at their jobs.
Should you jog too? If you do, be sure to ask your doctor for advice. Jogging may be too much exercise
for you.
Does jogging cost much? No, it costs almost nothing. But it is very important to have a good pair of shoes
that are made especially for jogging. They protect your feet and legs from the shock of running on hard
surface.
How fast should you go? Jog with a friend and talk to each other as you run. If you have difficulty in
talking, you"re going too fast.
How far should you jog? Remember not to go too far too soon. In fact, you should walk, not run, the first
few times. Then do some short jogs, but no more than what you can do comfortably. After that, increase your
distance a quarter or half mile every two weeks or so. Maybe in a few years, you can run in a marathon too, as
thousands of people do.
B. jogging as an exercise
C. jogging in a safe way
D. jogging as a way to marathon
B. Many people think that jogging is a set of one"s willpower (意志力)
C. Jogging is time-consuming.
D. You should not talk while jogging.
B. Have a sports suit.
C. Remember not to go too far too soon at the beginning.
D. Ask your doctor for advice.
B. One can start jogging at any time and in any place.
C. It is a very good exercise.
D. One can talk with one"s friend while jogging.
B. Para. 2.
C. Para. 3.
D. Para. 4.
