world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in
now. Visible ahead is serious stress involving population, resource and environment. Despite greater food
output, people in the world will be poorer in many ways than they are today.
For hundreds of millions of the extremely poor, the outlook for food and other necessities of life will
be no better, for many it will be worse.
While the economies of the developing countries are expected to grow at a faster rate than those of
the industrialized nation, the total national product per head in most less developed countries remains low.
The existing gap between the rich and poor nations will further widen.
World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase
goes to the countries that already have relative higher per-head food consumption. Mean-while, per-head
consumption of food in the developing countries will scarcely improve or will actually fall far below the
present inadequate level. What is worse is that prices for food are expected to double.
As a result, many less developed countries will have increasing difficulties meeting energy needs. For
the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful.
Regional water shortage will become more severe. In the 1970-2100 period population growth will
require twice as much water as it does today in nearly half the world. Still greater increases would be needed
to improve standards of living. Development of new water supply will become more costly.
B. the resource will become more than enough
C. in most developing countries people will have less food than they have today
D. the living standards of the world"s population will improve greatly
B. things will be a little better
C. it will be necessary for them to improve their housing
D. it will be impossible to obtain enough necessities of life
B. to any country in the world that needs it
C. to developing countries
D. to those countries that already have high per-head consumption
B. water and air pollution
C. water and food shortages
D. food production and consumption

also know that most diets and quick weight-loss plans have about as much substance as a politician"s campaign
pledges. You"re better off finding several simple things you can do on a daily basis-along with following the
cardinal rules of eating more vegetables and less fat and getting more physical activity. Together, they should
send the scale numbers in the right direction: down.
1. Treat high-calorie foods as jewels in the crown. Make a spoonful of ice cream the jewel and a bowl
of fruit the crown. Balance a little cheese with a lot of salad.
2. Eat five or six small meals or snacks a day instead of three large meals. A 1999 South African
study found that when men ate parts of their morning meal at intervals over five hours, they consumed almost
30 percent fewer calories at lunch than when they ate a single breakfast. Other studies show that even if you
eat the same number of calories distributed this way, your body releases less insulin, which keeps blood sugar
steady and helps control hunger.
3. Walk for 45 minutes a day. The reason we"re suggesting 45 minutes instead of the typical 30 is that a
Duke University study found that while 30 minutes of daily walking is enough to prevent weight gain in most
relatively sedentary (久坐的) people, exercise beyond 30 minutes results in weight and fat loss. Burning an
additional 300 calories a day with three miles of brisk walking (45 minutes should do it) could help you lose 30
pounds in a year without even changing how much you"re eating.
4. Bring the color blue into your life more often. There"s a good reason you won"t see many fast-food
restaurants decorated in blue; Believe it or not, the color blue functions as an appetite suppressant. So serve up
dinner on blue plates, dress in blue while you eat, and cover your table with a blue tablecloth. Conversely, avoid
red, yellow, and orange in your dining areas. Studies find they encourage eating.
5. Clean your closet of the "fat" clothes. Once you"ve reached your target weight, throw out or give
away every piece of clothing that doesn"t fit. The idea of having to buy a whole new wardrobe if you gain the
weight back will serve as a strong incentive to maintain your new figure.
B. give advice on losing weight
C. persuade you to go on a diet
D. talk you into giving away clothing that doesn"t fit
B. the color blue encourages eating.
C. many fast-food restaurants are decorated in blue.
D. Eating five or six small meals helps reduce weight.
B. a big meal helps control hunger
C. a 45-minute walk a day discourages your appetite for food
D. buying new clothes can reduce weight
B. people should cat more fruit to lose weight
C. going on a diet is they only way to lose weight
D. restaurants should serve food with blue plates
millions of people in the developing world to wash their hands with soap.
Experts say people around the world wash their hands but very few use soap at so-called critical moments.
These include after using the toilet, after cleaning a baby and before touching food.
Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap. The
goal, they say, is to create a culture of handwashing with soap. The organizers say all soaps arc equally
effective at removing disease-causing germs (细茵). They say the correct way to wash is to wet your hands
with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails.
Then, wash well under running water. Finally, dry your hands with a clean cloth.
The Partnership says soap is important because it increases the time that people spend washing. Soap also
helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell, which increases
the chances that people will wash again.
It also says that washing hands with soap before eating and after using the toilet could save more lives than
any medicine. It could help reduce cases of diarrhea (痢疾), which is the second leading cause of child deaths,
killing more than one and a half million children a year, by almost half.
B. To wash hands with soap.
C. To take action to wash hands.
D. To wash hands often.
a. Washing hands well.
b. Covering hands with soap.
c. Drying hands.
d. Rubbing hands with soap.
e. Wetting hands.
B. e-d-a-b-c
C. a-c-b-d-e
D. c-b-d-a-c
B. It helps to remove a lot of germs from hands.
C. It attracts people to do more handwashing.
D. It gets all people into the habit of washing hands.
B. causes the greatest number of child deaths
C. can be prevented to some degree by washing hands with soap
D. can"t be cured without washing hands
countries. They say people should eat more of the same kind of food eaten by humans living more
than 10,000 years ago. 1_______
The scientists say that human life has changed greatly. Our bodies have not been able to deal with
these changes in lifestyle and this has led to new kinds of sicknesses. 2_______ They are called "diseases
of civilization". Many cancers and diseases of the blood system arc examples of such diseases.
The scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little
alcohol or tobacco, probably none. 3_______ However, a change in food is one of the main differences
between life in ancient times and that today.
Stone Age people hunted wild animals for their meat,which had much less fat than domestic (驯养的)
ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products,
and they made very little use of grains. 4_______ We eat six times more salt than our ancestors and we
eat more sugar as well. We eat twice as much fat but only one third as much protein (蛋白质) and much
less vitamin C.
5_______ But the scientists say that we would be much healthier if we cat much the same way the
ancient people did, cutting the amount of fat, salty and sweet food.
B. But today, we enjoy eating a lot of these.
C. In that case, they would live a much healthier life.
D. Ancient people also got lots of physical exercise.
E. These new sicknesses were not known in ancient times.
F. People today probably don"t want to live like our ancestors.
G. Modern people used to suffer from "diseases of civilization".
Like distance runners on a measured course, all of us will move through time in a roughly predictable
pattern.
In the first stage of our lives, we develop and grow, reaching toward the top of physical vitality (energy).
After we grow up, however, the body begins a process of gradually wearing out.
A new awareness of physical fitness may help lengthen our years of health and vitality, yet nothing we
do will work to stop the unavoidable force of aging.
Most of the changes of aging take place deep inside the body. The lungs become less able to take in
oxygen. Powerful muscles gradually lose their strength. The heart loses power and pumps less blood. Bones
grow easier to break.
Finally, we meet a stress, a stress that is greater than our physical resistance. Often, it is only a minor
accident or chance infection (a disease caused by virus), but this time, it brings life to an end.
In 1932, a classic experiment nearly doubled the lifetime of rats, simply by cutting back the calories (unit
for measuring the energy value of food) in their diet. The reason for the effect was then unknown.
Today, at the university of California at Berkley, Dr. Paul Seagle has also greatly lengthened the normal
lifetime of rats. The result was achieved through a special protein (蛋白质) limited diet, which had a great
effect on the chemistry of the brain. Seagle showed that within the brain, specific chemicals control many
of the signals that influence aging. By changing that chemical balance, the clock of aging can be reset.
For the first time, the mystery (something that is difficult to understand or to explain) of why we age is
being seriously challenged. Scientists in many fields are now making striking and far-reaching discoveries.
An average lifetime lasts 75 years, yet in each of us lies a potential for a longer life. If we could keep the
vitality and resistance to disease that we have at age twenty, we would live for 800 years.
B. Stress.
C. Aging.
D. Physical resistance.
B. physical fitness can"t stop the force of aging
C. human"s lifetime will last longer than 75 years
D. all of the changes of aging take place deep inside the body
B. By cutting the calories in their diet
C. By resetting their clock of aging
D. By keeping their physical fitness
B. The Mystery of Human Life
C. Ways to lengthen Human Life
D. The Breakthrough in the Study of Aging
officials announced the results of the latest tiger count. The census (统计) totaled 1,706 tigers in forests
across the Asian country-about 300 more than four years ago. "These numbers give us hope for the future
of tigers in the world," said Jim Leape, international director of the World Wildlife Fund.
A century ago, about 100,000 tigers lived in India"s forests. But by 2002, a count showed that there were
only 3,600 left. The number dropped to 1,411 in 2007. What caused India"s tiger population to shrink so
dramatically?
More than anything else, experts say, development has taken a toll. People have moved into tiger territory
and destroyed much of the animal"s habitat. Today, tigers live on a just small part of the land they occupied
100 years ago.
Illegal hunting has also contributed to the decline. Poachers (盗猎者) can demand high fees for tiger parts,
which are a key ingredient in traditional Chinese medicine. The parts from one tiger can sell for tens of
thousands of dollars.
India"s news is a step in the right direction. But while the number of tigers has increased there in the last
four years, the animals" habitat has shrunk. Roads and construction projects have blocked off many tiger
corridors-routes used by the big cats to go from one forest to another. "Securing these corridors should be
taken up as a priority," says Rajesh Gopal, of the National Tiger Conservation Authority.
Last November, leaders from the 13 countries that are home to wild tigers met in St. Petersburg, Russia,
to develop a plan to help the endangered cats. They set a goal to double the world"s tiger population by the
year 2022. Will we reach that goal? With India"s tiger population on the rise and conservationists around the
world focused on helping the big cats, it seems it just might happen.
B. reduce
C. disappear
D. remove
B. Roads and construction projects have bridged tiger corridors.
C. Some India"s tigers have been hunted for to attract visitors.
D. Too many tigers are used in making traditional Chinese medicine.
B. Rajesh Gopal is in charge of the World Wildlife Fund
C. the world"s tiger population will surely be doubled by 2022
D. international efforts are being made to protect India"s tigers
B. Objective
C. Optimistic
D. Concerned
