so it needs proper treatment and proper nourishment (营养).The old saying "An apple a day keeps
the doctor away "is not as silly as some people think. The body needs fruit and vegetables because
they contain vitamin C. Many people take extra vitamins in pill form, believing that these will make
them healthy.
But a good diet is made up of nourishing food and this gives all the vitamins you need. The body
doesn"t need or use extra vitamins, so why waste money on them?
In the modern western world, many people are too busy to bother about eating properly. They
throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or
made worse by bad eating habits is frightening,
B. your body is made up of the food you eat
C. what you eat has great effect on your health
D. the more you eat, the fitter you will feel
B. the apple is the best among all kinds of fruits
C. apples can take the place of doctors
D. an apple is a sure cure for illness
B. often eating apples is a good habit
C. taking extra vitamin pills is completely useless
D. a good diet is of great importance for our health
B. lots of people"s illnesses are caused or made worse by bad eating habits

Most people know this joke. But recently, some people have been much more worried about how
the grizzly(灰白的) bear and mountain lion can cross the road.
"Millions of animals die each year on U.S. roads," the Federal Highway Administration reports. In
fact , only about 80 ocelots(豹猫), an endangered wild cat, exist in the U. S. today. The main reason?
Road kill.
"Eco-passages" may help animals cross the road without being hit by cars. They are paths both over
and under roads. "These eco-passages can be extremely useful, so that wildlife can avoid road accidents," said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona
University found foot marks left by mountain lions on an eco-passage that went under a highway. This
showed that the lions used the passage.
Builders of eco-passages try to make them look like a natural part of an area by planting trees on and
around them. Animals seem to be catching on. Animals as different as salamanders(火蜥蜴)and
grizzly bears are using the bridges and underpasses(地下通道,下穿交叉道).
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might
see an animal overpass(越过,通过)!
_____.B. the driving conditions have improved greatly
C. the
measure for protecting wildlife fails
to workD. wild animals have become more dangerous
B. a fence(栅栏) built for the safety of the area
C. a passage(通道) for animals to cross the road
D. a bridge for animals to get over a river
B. animals begin to learn to use eco-passages
C. animals are crossing the road in groups
D. animals are becoming safer
B. call on drivers to be careful when seeing animals on roads
C. introduce a new way to help protect animals
D. tell us the main reason for the killing of animals in the US
environment. Often, this waste produced by major industries and people is harmful to both nature
and human life.
One of the main causes of the large amount of dangerous waste is that people do not realize
how large a problem it is. Because it can be simply removed and sent to a landfill(废渣填埋场),
the problem is often believed to end there. In addition, industries have often shown an unwillingness
to find ways to deal with dangerous waste because of the related expenses. Many industries and
governments build simple landfills to store waste, and often just pour waste chemicals into nearby
bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste.
The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive
to get rid of these chemicals or to store them in a way safe to human life and the environment.
Every year, major health problems result from dangerous waste. Sadly, it is often only after
someone has died or become seriously ill that governments will take measures to reduce levels of
harmful waste.
Some governments have realized how serious the dangerous waste problem is and are now trying
to settle this problem. They are also trying to limit the amount of waste industries are allowed to
produce.
Not only governments but ordinary people as well must work together to solve the problem.
They can choose not to buy those products which require the production of dangerous waste, and
produce less harmful waste themselves. Many scientists think that waste production can be cut. The
waste can be reduced by at least one third using existing technologies and methods.
B. Danger of Harmful Waste to Mankind
C. Dangerous Waste and Water Pollution
D. Environmental Protection
B. do not know where to place the dangerous waste
C. are not clear about how serious the dangerous waste problem is
D. are not sure about where harmful waste ends
B. How to increase their production.
C. How to store harmful waste.
D. How to cut down the related costs.
B. Present technologies have settled the harmful waste products.
C. Everyone should obey the government rules for the problem.
D. To solve the problem requires the efforts of the whole society.
about it than any of the other illnesses.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused
by viruses passing on from person to person. You catch a cold by coming into contact,directly or
indirectly, with someone who already has one. If cold causes colds,it would be reasonable to expect the
Eskimos to suffer from them forever. But they do not. And in distant and isolated Arctic regions explorers have reposed being free from colds until coming into contact again with infected(感染的)people from the
outside world by way of packages and mail dropped from airplanes.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they
gave themselves to the discomforts of being cold and wet for long periods of time. After taking hot baths,
they put on bathing suits,allowed themselves to be doused(浸入)with cold water, and then stood about
dripping wet in drafty(通风的)room. Some wore wet socks all day while others exercised in the rain
until close to complete tiredness. Not one of the volunteers came down with a cold unless a cold virus
was actually dropped in his nose.
If, then,cold and wet have nothing to do with catching colds,why are they more frequent in the
winter? Despite the most pains--taking research,no one has yet found the answer. One explanation
offered by scientists is that people are more likely to stay together indoors in cold weather than at other
times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such
as aspirin,but all they do is to relieve the symptoms.
B. viruses are the factors causing colds.
C. colds are more serious than other illnesses.
D. the idea that cold leads to colds doesn"t stand up.
B. taking hot baths made the volunteers easy to be tired.
C. it was viruses not wet and cold that made people have colds.
D. people who would like to exercise in the rain got colds more easily.
B. viruses can go into people"s warm bodies more easily in winter.
C. staying together indoors makes it easier for viruses to pass on.
D. People are usually weak because of the extreme cold in winter
B. the myths about colds.
C. the experiments on colds.
D. the continued spread of common colds.
obvious health benefits that result from the elimination (排除) of red meat from your diet. In
general, vegetarians have lower levels of blood fats, cholesterol (胆固醇) and triglyceride
(甘油三酸脂) than meat eaters of a similar age and social status.
High levels of blood fats are associated with an increased risk of heart disease. Lacto-ovo
vegetarians (乳类蛋类素食者), who eat eggs and dairy products, have higher cholesterol levels
than vegans (绝对素食者). Even among lacto-ovo vegetarians, however, cholesterol levels
are generally lower than they are among meat eaters.
Researchers have found that older men that eat meat six or more times a week are twice as
likely to die of heart disease as those that don"t have meat. Among middle-aged men, meat eaters
were four times more likely to suffer a fatal heart attack, according to the study.
As for women, who are partly protected by their hormones and generally develop heart disease
later in life than men, the risk of fatal heart disease has been found to be lower only among older
vegetarians. In a 1982 study of more than 10 000 vegetarians and meat eaters, British researchers
found that the more meat people consumed, the greater risk they had of suffering a heart attack.
Though eliminating meat from the diet is likely to reduce your consumption of heart-damaging
fats and cholesterol, continuing to eat large amounts of high-fat dairy products and cholesterol-rich
eggs can reduce the benefit. The introduction of more vegetables, fruit and raw foods will definitely
enhance the benefits of giving up eating meat.
EXCEPT their_________.
A. heart rate
B. cholesterol levels
C. triglyceride levels
D. blood fat levels
B. eliminating red meat from your diet is no good for your health
C. eating more vegetarian food can have obvious benefits for your health
D. the possibility of meat eaters developing heart disease is twice as high as that for vegetarians
B. vegetarians don"t eat eggs and dairy products
C . vegans have the lowest cholesterol levels
D. vegans do not have the risk of catching heart disease
A. Women tend to suffer from heart disease earlier men.
B. Older women have less chance of suffering from heart disease than young women.
C. Eating more meat may increase a person"s chance of developing heart disease.
D. Eating meat has little influence on older people"s health.
People who have such an addiction are compulsive: they have a very powerful psychological need
that they feel they must satisfy. According to psychologists, many people are compulsive spenders.
They feel that they must spend money. This compulsion, like most others, is impossible to explain
reasonably. For compulsive spenders who buy on credit, charge accounts are even more exciting
than money. In other words, compulsive spenders feel that with credit, they can do anything. Their
pleasure in spending large amounts is actually greater than the pleasure that they get from the things
they buy.
There is even a special psychology of bargain hunting. To save money, of course, most people
look for sales, low prices, and discounts. Compulsive bargain hunters,however, often buy things that
they don"t need just because they are cheap. They want to believe that they are helping their budgets,
but they are really playing an exciting game. When they can buy something for less than other people,
they feel that they are winners. Most people, experts claim, have two reasons for their behavior: a
good reason for the things that they do and thereal reason.
It is not only scientists, of course, who understand the psychology of spending habits, butalso
business people. Stores, companies, and advertisers use psychology to increase business. They
consider people"s needs for love, power, or influence, their basic values, their beliefs andopinions,
and so on in their advertising and sales methods.
Psychologists often use a method called "behavior therapy (疗法)"to help individuals solvetheir
personality problems. In the same way, they can help people who feel that they haveproblems with
money.
B. in order to satisfy his or her basic needs in life
C. just to meet his or her strong psychological need
D. entirely with an irrational eagerness
B. because they like to show off their success in getting things for less money
C. because they have money problem
D. because they want to save money to help heir budget
B. the purchasing habits of compulsive spenders
C. a special psychology of bargain hunting
D. the use of the psychology of spending habits in business
B. need special treatment
C. can"t be cured
D. can never get any help to solve their problems with money
