been arguing about the benefits and dangers of wolves. Some groups
believe wolves should be killed. Other people believe wolves must be
protected so that they will not disappear from the wilderness(荒野).
For Killing Wolves
In Alaska, the wolves almost disappeared a few years ago,
because hunters were killing hundreds of them for sport.
However, laws were established to protect the wolves from
sportsmen and people who catch the animals for their fur. So
the wolf population has greatly increased. Now there are so
many wolves that they are destroying their own food supply.
A wolf naturally eats animals in the deer family. People in
the wilderness also hunt deer for food. Many of the animals
have been destroyed by the very cold winters recently and by
changes in the wilderness plant life. When the deer can"t find
enough food, they die.
If the wolves continue to kill large numbers of deer, their
prey(猎物)will disappear some day. And the wolves will,too.
So we must change the cycle of life in the wilderness to balance
the ecology. If we killed more wolves, we would save them and
their prey from dying out. We"d also save some farm animals.
In another northern state, wolves attack cows and chickens
for food. Farmers want the government to send biologists to
study the problem. They believe it necessary to kill wolves in
some areas and to protect them in places where there is a small
wolf population.
Against Killing Wolves
If you had lived long ago, you would have heard many
different stories about the dangerous wolf. According to most
stories, hungry wolves often kill people for food. Even today,
the stories of the "big bad wolf" will not disappear.
But the fact is wolves are afraid of people. and they seldom
travel in areas where there is a human smell. When wolves eat
other animals, they usually kill the very young, or the sick and
injured. The strongest survive. No kind of animal would have
survived through the centuries if the weak members had lived.
And has always been a law of nature.
Although some people say it is good sense to kill wolves,
we say it is nonsense! Researchers have found wolves and their
prey living in balance. The wolves keep the deer population
from becoming too large, and that keeps a balance in the
wilderness plant life.
The real problem is that the areas where wolves can live
are being used by people. Even if wilderness land is not used
directly for human needs. The wolves can"t always find enough
food. So they travel to the nearest source, which is often a
farm.Then there is danger. The "big bad wolf" has arrived!
And everyone knows what happens next.
following reasons EXCEPT that____.
B. they kill large numbers deer
C. they attack cows and chickens for food
D. they destroy the wilderness plant life
B. there is too small a wolf population in the wilderness
C. there are too many deer in the wilderness
D. wolves are afraid of people and never attack people
B. they always go against the law of nature
C. they might help this kind of animals survive in nature
D. they disturb the ecological balance in the wilderness
B. wolves will kill people and people will in turn kill them
C. wolves will find enough food sources on farms
D. people will leave the areas where wolves can live

ways we canprotect ourselves when we travel.
You are safer in a large car. People in small cars are
injured more often and more severely than people traveling in
large cars. Factories of small cars are strengthening their
products" safety, which helps. But the mix of large cars and
small cars on the road is the main reason of the problem.
Being thrown into glass and metal car parts, or being
thrown from the car, can really damage to you. That"s why
safety belts should be worn. The safety belt"s main purpose is
if your car has a sudden crash with another vehicle or
object, or if it rolls over. A belt can reduce the chance of fatal
injury by 45% and the chance of serious injury by 50%.
Air bags are important. More than half of all new cars sold
have air bags. Air bags provide protection in frontal ( 正面的)
crashes-the type of crash that kills the most drivers-
when they are also wearing safety belts. Most people are
demanding air bags in the cars they buy. But the protection
provided by air bags is limited in side or rear crashes; effective
as they are, they can"t take the place of safety belts.
Drunk driving crashes are less likely to happen if you don"t
drink. Drunk driving is the most serious problem. Many people
have realized that drunk driving can lead to death and injury,
prison time and other results. There are movements to
strengthen penalties ( 处罚) for drinking and driving.

harder. Now a new study by researchers at Penn State suggests
that the techniques that work for losing weight aren"t
necessarily the same as those that help keep you slim.
[2]First the researchers surveyed over 1,100 people who
had achieved significant weight loss and maintained ( 维持) it.
The researchers identified 36 weight-loss and weight-
maintenance practices that at least 10% of the group used.
[3]Then the researchers conducted a national telephone
survey of overweight people who had tried to lose weight and
keep it off with varying success: about 11% reported
successfully losing weight, and 21% were able to maintain that
loss for at least a year.
[4] The survey found people who ____ did so by
participating in weight loss programs, cutting back on sugar,
eating healthy snacks, not skipping meals and participating in
different types of exercise.
[5]Still,say many nutrition and obesity experts. The basic
principles of weight loss and maintenance are the same; you
have to eat a healthy diet and increase your exercise. People
who lose weight and keep it off tend to eat significantly
healthier foods and do a lot more exercise than the average
American.
[6] But what may maintain between weight-loss and
maintenance is a person"s attitude; rather than focusing on
actively losing weight in the short term. People have to start
focusing on long-term, permanent lifestyle changes and
behaviors, if they want to maintain the weight that"s been lost.
The key to success, experts agree, is motivation, not
necessarily the particulars of your weight-loss program.

charges are given for heavy use, but the solar system still makes sense for low-energy users such as
myself.
So much of Americans" carbon footprint results from buildings-about 43%, according to the U.S.
Department of Energy. I"m in a household of 1.5 (mom and 7-year-old), and we use only about 4
kilowatt hours of electricity per day, something we"ve managed through behavioral changes, such as
turning off the lights in rooms after we"ve exited, and through in-home efficiencies (效率), such as
swapping out all my light bulbs for energy-saving ones and using power boards that can turn off DVD
players, coffee makers and other electrical equipment.
Using less electricity means I can get by with a smaller, less expensive solar system that not only
covers my use but also produces a credit on my power bill. Going solar also meant my house was
upgraded with a time-of-use meter. This type of meter allows me to receive credit for the electricity I
produce during peak hours when electricity costs the most, but pay the least for the electricity during
off-peak hours, when I recharge my cell phone and laptop and perform other tasks requiring power.
The downsides are that I am tied in to the grid (电网) and still affected by power failure, and I now
have solar panels (太阳能电池板) that need to be cleaned. It"s a subject of debate, but REC Solar said
dirty panels decrease energy production by 6% to 8%.Many panel producers recommend cleaning
panels at least once during the summer. I wash mine whenever they look dirty or dotted with bird
droppings, which is about every other week.
I think $6,000 is a small price to pay, not only for panels that should produce my next 20 years of
electricity, but also for the greenhouse gases I"m not creating.
B. The tips on reducing electricity use.
C. The benefits of using solar systems.
D. The importance of protecting the environment.
B. To save time.
C. To save energy.
D. To save money.
B. disadvantage
C. disapproval
D. disagreement
B. to protect the environment
C. to make them look better
D. to avoid power failure

But rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation-the
citizens of Tuvalu will have to leave their homeland.
During the 20th century, sea level rose 8-12 inches. As a result, Tuvalu has experienced lowland
flooding of salt water which has polluted the country"s drinking water.
Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation
suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher
surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an
international. agreement calling for industrialized nations to reduce their greenhouse gas emissions (导
致温室效应的气体排放 ) , which are a main cause of global warming. "By refusing to sign the
agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live
where their forefathers
have lived for thousands of years," Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both
countries .
Tuvalu is not the only country that is vulnerable(易受影 响的) to rising sea levels. Maumoon
Gayoon, president of the Maldives, told the United Nations that global warming has made his country
of 311,000 an "endangered nation".

model to predict how just three grams less a day would affect heart disease in the United States.
The result:10% fewer heart attacks.8% fewer storkes.4% fewer deaths.11% fewer new cases of
heart disease. And 240 billion dollars in health care savings.
Researchers found it could prevent 100,000 heart attacks and 92,000 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of
California San Francisco was the lead author. She says people would not even notice a difference in
taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at
Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium(钠),which is how foods may list their
salt content.
The government says the average American man eats ten grams of salt a day. The American Heart
Association advises no more than three grams for healthy people. It says salt in the American diet has
increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can
mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction
Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government
interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list
calorie information. Now a study by the Seattle Children"s Research Institute shows that the calorie
information on the menu can influence what parents order for their children.
B. stroke
C. blood pressure
D. heart attack
B. 900,000
C. 100,000
D. 92,000
B. the American Heart Association suggests less than 3 grams of salt a day for everyone
C. Americans ate no more than 5 grams of salt per day in the 1970s
D. the less salt one eats, the healthier he will be
B. require fast food places to list salt information
C. inform people of the harm that salt does to health
D. put pressure on food companies and restaurants
B. Bloomberg is very successful in his career
C. parents must pay great attention to calorie information
D. a new study is being done about calorie information
