was in danger. They hoped that governments would act quickly in order to conserve nature. Here is one
example of the problem. At one time there were 1, 300 different plants, trees and flowers in Holland, but now
only 866 remain. The others have been destroyed by a modern man and his technology. We were changing the
earth, the air and water, and everything that grows lives. We can"t live without these things. If we continue like
this, we shall destroy ourselves.
What will happen in the future? Perhaps it is more important to Ask "What must we do now?" The people
who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is
necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so
on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometers of their rivers. Young people may hear about conservation through a record called "No one"s going to change our world". It
was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.
B. Holland does not need so many plants, trees and flowers
C. many plants, trees and flowers are dangerous
D. many plants, trees and flowers do not grow there any more
B. an idea that nobody would accept
C. a record calling all people to conserve nature
D. a rule worked out by the United States
B. We should clean the banks of our rivers.
C. We should know what would happen in the future.
D. We should know what we must do and begin to do now.

They attacked (袭击) the cats and dogs. Sometimes a great number of them knocked down a man or woman
walking home at night. The rats were very large in size and they harmed many people. The government ordered everybody to kill rats. Most people were lazy, so they did not kill many.
Then the government promised to pay some money for each dead rat. That made the people very happy.
They killed thousands of rats every day. A government officer put all the dead rats in a big pile. Sometimes a
man brought hundreds in one day. After two weeks there were not many rats in the city, but people still
brought many rats to the government office. The government officer thought that people were stealing dead
rats from the pile. He ordered his men to dig a deep hole and put the rats in it. Soon there were no more rats
and the government did not pay any more money.
B. How to Kill Rats.
C. Newtown-City of Rats.
D. How Newtown People Became Rich.
effort, and not much money, most of us could reduce our energy diets by 25 percent or more-doing the
Earth a favor while also helping our wallets. Not long ago, my wife, PJ, and I tried a new diet-not to lose a
little weight but to answer an annoying question about climate change. Scientists have reported recently that
the world is heating up even faster than predicted only a few years ago, and that the consequences could be
severe if we don" t keep reducing emissions (排放) of carbon dioxide( CO2) and other greenhouse gases that
are trapping heat in our atmosphere.
We decided to try an experiment. For one month we recorded our personal emissions of CO2. We wanted
to see how much we could cut back, so we went on a strict diet. The average US household (家庭) produces
about 150 pounds of CO2 a day by doing common-place things like turning on air-conditioning or driving cars.
That"s more than twice the European average and almost five times the global average, mostly because
Americans drive more and have bigger houses. But how much should we try to reduce?
For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the
Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in
personal emissions to keep the world from reaching extremely important tipping points, such as the melting
(融化) of the ice sheets in Greenland or West Antarctica."To stay below that point, we need to reduce CO2
emissions by 80 percent." he said.
Good advice, I thought. I" d opened our bedroom windows to let in the wind. We" d gotten so used to
keeping our air-conditioning going around the clock. I" d almost forgotten the windows even opened. We
should not let this happen again. It" s time for us to change our habits if necessary.
A. it is necessary to keep the air-conditioning on all the time
B. it seems possible for every household to cut emissions of CO2
C. the average US household produces about 3,000 pounds of CO2 a month
D. the average European household produces about 1, 000 pounds of CO2 a month
goal here is to limit carbon dioxide and other greenhouse gases, which are closely associated with the big
problem of global-warming.
Strategy 1:Bring your own cup to Starbucks.
You"ll get a 10-cent discount, and it"s one less paper cup to end up in a dustbin.
The store won"t create more waste when they throw away a cup.
Strategy 2:Tum off your computer.
When in standby mode, your PC is still using energy.
Turning off a monitor for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds!
Strategy 3:Reuse plastic bags.
Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag.
You"re reducing pollution. The amount of oil it would take to make just 14 plastic bags would run your car
for one mile.
Strategy 4: Use recycled paper in the bathroom.
Most of the toilet paper we use is made from trees found in forests previously untouched by humans.
If every household replaced one roll of toilet paper with a recycled one, 424, 000 trees would still be
standing. Look for eco-paper towels too.
Strategy 5: Buy energy-efficient appliances (电器).
Replace the old fridge with an Energy Star appliance and you"ll use 15 percent less energy. It might be a
little expensive to buy, but you"ll save money on your electricity bills and help the environment.
If we all used one Energy Star appliance at home, it would be like planting 1. 7 million acres of new trees.
Strategy 6 Plant a tree.
Adding green to your garden is beautiful and earth-pleasing.
Just one tree will help make cleaner air and save the environment from 5,000 pounds of hot carbon dioxide
each year.
B. Ways to be earth-friendly
C. Strategies to end global-warming
D. Ways to limit carbon dioxide
B. It will help to reduce a great deal of CO2.
C. It will save the amount of oil that runs your car for a mile.
D. It will be like planting 1.7 million acres of new trees.
B. Strategies 2&5.
C. Strategies 3&6.
D. Strategies 4&5.
B. They all cut down the amount of the use of paper.
C. They all result in producing less greenhouse gases.
D. They all aid to preserve our trees and forest.
or skipping rope for hours, you weren"t thinking fitness, you were thinking entertainment. But in this age of
high-tech home equipment and underused gym member-ships, the simple joy of jumping rope has been
forgotten. Rediscove ring" it will give you a total-body exercise you can find.
Although considered as an excellent form of exercise, jumping rope has never gained widespread
acceptance because of two funda mental reasons. First, most people recognize jumping rope as an ex-cellent
form of cardiovascular (心血管的) exercise, but they also believe that it is simply too difficult. In other words,
they don"t think they"ll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial
physical outcome. Second, many view it as somewhat boring and overly repetitive not as something fun or
enjoyable.
As a matter of fact, jumping rope can be great fun if you find a proper way to practice it. Instead of doing
the usual two-foot bounce over and over again, people good at rope-jumping often change their pattern every
10 or 20 jumps. A single bounce, a double bounce, a skip, a knee-up, side swings, as well as a variety of other
easy-to- learn free-style rope-jumping.
Now researchers are learning that jumping rope also prepares the brain for learning. It is an exercise
allowing both brain hemi- spheres to perform in parallel to each other. In short, jumping rope can be a life-long
activity requiring little equipment, time and space, yet leading to a much healthier life.
B. people now have more advanced equipment
C. racing around the playground was preferred
D. people now like to have exercise in a gym
B. it is neither easy nor enjoyable
C. it is considered boring and repetitive
D. it requires little equipment, time and space
B. the usual way should not be used
C. the easiest way is always the best
D. there are many ways to follow
B. is suitable for students only
C. helps both brain hemispheres work together
D. can be dangerous for old people
for man-made global war ming was"stronger than ever".
After analyzing more than 100 scientific papers published in the last few years, a team of British
researchers say there is an"in creasingly small possibility" that the world is warming up because of natural
variations (变动) in climate.
Instead, man-made global warming-caused by the burning of fossil fuels-is making its mark on every
continent and ocean, they say.
The studies used computer models to see whether changes in air temperature, sea ice, sea temperature,
wetness, rainfall and ocean saltiness recorded in the last 50 years could be explained by nature.
Since 1980,the average global temperature has increased by around0.5℃,they found. The same warming
pattern was also found deep in the world"s oceans.
Natural forces such as volcanic eruptions and returning chan ges in the brightness of the sun could not
explain what was happen- ing to the world"s climate, Dr Stott said.
The sun"s output had actually fallen over the last 50 years, he said.
Even if the sun had got warmer over the last few decades-as some skeptics say-both the upper and lower
layers of the atmos phere should have got hotter.
However, in the last 50 years the lower atmosphere has warmed while the upper atmosphere has actually
cooled, Dr Stott said.
Drier parts of the world are getting drier, while wetter areas are getting more rain-a finding in agreement
with man-made climate change, the report found.
And the amount of mid summer sea ice in the Arctic is also declining over time-even with the natural
yearly variations, the study found.
The study comes along with growing public doubt about climate change.
B. mankind isn"t to blame for global warming
C. mankind is to blame for global warming
D. global warming will disappear sooner or later
B. The increase of the brightness of the sun.
C. The warming pattern of the world"s oceans.
D. The burning of fossil fuels by the human being.
B. believe global warming will disappear sooner or later
C. doubt the global warming will disappear sooner or later
D. doubt the global warming is caused by humankind
B. Many people don"t believe the study of the British researchers now.
C. The public have been used to the climate changes these years.
D. The result of the study comes from the opinions of the public.
