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.

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. behave strangely
C. often attack other animals
D. enjoy walking around
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.
B. his height
C. his weigh
D. his character
B. do any housework
C. think a lot
D. go out for relaxation
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.

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.
Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of
food that people should eat every day. They are: (1) green and yellow vegetables of all kinds; (2) citrus (柑橘)
fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds,fish and eggs; (5) milk
and food made from milk; (6) bread or cereal (谷类), rice is also in this kind of food; (7) butter, or something
like butter.
Paragraph 2
People in different countries and different places of the world eat different kinds of things. Foods are
cooked and eaten in many different kinds of ways. People in different countries eat at different times of the
day. In some places people eat once or twice a day; in other countries people eat three or four times a day.
Scientists say that none of the differences is really important. It doesn"t matter whether foods are eaten raw
(生的) or cooked, canned or frozen. It doesn"t matter if a person eats dinner at four o"clock in the afternoon
or at 11 o"clock at night. The important thing is what you eat every day.
Paragraph 3
There are two problems, then, in feeding the large number of people on the earth. The first is to find some
ways to feed the world"s population so that no one is hungry. The second is to make sure that people
everywhere have the right kinds of food to make them grow to be strong and healthy.
B. potatoes, carrots, rice, bread
C. oranges, bananas, fish, tomatoes

B. cook their food in the same way
C. have their meals at the same time
D. eat food in different ways
B. There are too many people in the world.
C. One of the problems is that no one is hungry.
D. The scientists are trying to make people grow to be strong and healthy.
B. What to do with the two problems.
C. How to cook food in different ways.
D. Why people eat different kinds of food.
Farmers use different kinds of soil conservation methods to protect their land against damage from farming
and the forces of nature. One important form of soil conservation is the use of windbreaks.
Windbreaks are barriers (栅栏) formed by trees and other plants with many leaves. Farmers plant them in
lines around their fields.
Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging
crops. They are very important for growing grains, such as wheat.
There have been studies done on windbreaks. Studies in parts of West Africa, for example, found that grain
harvests can be twenty percent higher in fields protected by windbreaks. This was compared to fields without
such protection.
Windbreaks can help protect a farmer"s land. However, windbreaks seem to work best when they allow a
little wind to pass through. If the wall of trees and plants blocks the wind completely, then violent air motions
will take place close to the ground. These motions cause the soil to lift up into the air where it will be blown
away.
For this reason, a windbreak is best if it has only sixty to eighty percent of the trees and plants needed to
make a solid line.
An easy rule to remember is that windbreaks can protect areas up to ten times the height of the tallest trees
in the windbreak.
There should be at least two lines in each windbreak. One line should be large trees. The second line, right
next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are best for
windbreaks.
Windbreaks not only protect land and crops from the wind. They can also provide wood products. These
include wood for fuel and longer pieces for making fences.
B. Protection.
C. Force.
D. Harvest.
B. To keep water in their fields.
C. To prevent their soil blowing away and wind destroying the crops.
D. To get more trees.
B. One with plants which have many leaves.
C. One with certain breaks between trees and plants.
D. One with as many trees or plants as possible.
B. To tell us how to get a higher harvest.
C. To let us know there are usually windbreaks around the fields.
D. To tell us how important it is to keep soil and crops.
