to go. This battery-powered, zero-emission (meaning it doesn"t pollute the air) vehicle runs mainly on
renewable energy. Solar panels on the Eclectic"s roof absorb sun rays when you"re driving. On windy
days, you can connect a machine to the car"s roof that collects energy from the wind while you"re parked.
The Eclectic"s top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged.
Zipping (迅速行进) around the neighborhood has never been better.
Here"s an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock"s tank (箱) with
water, add some lemon juice, and the clock will display the time without the need for environmentally harmful
batteries. There are two sets of metal electrodes (电极) inside the water tank. Water contains ions (离子)
that carry negative and positive charges. These ions complete a charge between the electrodes, creating
enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier.
(The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its original push
to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour.
In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle (角度).
You"re having a blast at your friend"s birthday party. But when it"s time to bring out the cake, everyone
crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera
captures the view from above. The Triops can take three pictures at once, each from different angles. You
can also record sounds and command the Triops to start shooting whenever it hears that noise. That"s one
smart camera.

D. The SSC doesn"t have anything to do with a rocket actually.
Besides giving off gases and dusts into the air, humans produce waste that is poured on the 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.

They collected or killed only enough for the clan"s survival. Early clans were nomadic, which means that
they did not stay in one place. Instead, they moved around, following the animals that were their main
food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to
protect the environment. The land had time to recover and animals had time to breed (繁殖) before the clan
returned for the next season.
As time went by, these small family clans joined with others to form larger groups for protection. Joining
with other clans gave them more hunters and more women to help cut up the meat and share it between
families. Eventually, people tamed (驯养) wild animals such as dogs and horses. People settled around rivers
and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to
areas where the plants grew. This development changed the environment.
Traditional forms of work also changed. Some people were hatter at performing a particular task than
other clan members, so they began to specialize in things they were good at doing. This also meant that they
began to exchange their goods for things that others produced.
People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals
were transported to places where they had not existed before. Specialization also gave people more free time.
So art, dance and music became important ways of expressing feelings and thoughts. This was how many
great civilizations started.
Compared to the past, modern civilization has experienced many changes to become the highly developed
society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions
and technology have made work easier.
However, pollution and other serious problems have also resulted from human progress. As concerned
citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.

In yesterday"s circus (马戏团) show, a tiger suddenly attacked its trainer and had to be shot dead.
As the circus packed up and left, circus officials said the show would go on, even without tigers.
However, the officials can"t simply turn a blind eye to the ethical problems left behind. Even before
this tragedy (悲剧), animal rights activists protested against keeping wild animals in unnatural conditions
and forcing them to suffer for the profit (利润) of circus organizers.
It is now time for us to take effective steps to make sure that circus animals are treated properly.
Circus Safe for Animals
Our circus recently suffered a most tragic event in its history. While we are thankful for the pity from
the public, we are also astonished by the opinion expressed in "Tragedy at the Circus."
First, our performing animals are not taken from the wild. As to the ethical problems. we always believe
humans and animals can-and should-live together nicely. To us, the performing animals are representatives
of their species (物种), and our circus is one of the only places left willing to support this special role of
performing animals in the existence of the species. Those who argue that circus life is harmful to animals
show little knowledge of these facts. Life in the "wild" is unsafe, but a continuous struggle for existence.
To overlook these reslities is the greatest fault against the animal kingdom.
This circus has proven that animals are stronger and smarter than we could imagine. Within the circus
is a joyful atmosphere for both animals and humans: people are educated, and species saved.
B. To express worries about ainimal trainers"safety.
C. To deal with the difficult situations of the circus.
D. To call for action to protect circus animals.
B. Continue its performances.
C. Use fewer wild animals.
D. Limit its profit.
B. They struggle continuously with human beings for existence.
C. They are helpful in saving their species.
D. They have equally natural living conditions as wild animals.
B. A newspaper article and a reply to it.
C. Two parts of a newspaper article.
D. Two newspaper reports.
I feel there arc a number of reasons for this.
Some people blame the fact that we arc surrounded (包围) by shops selling unhealthy, fatty foods, such as
fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom
cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less
take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with
this, because good eating habits begin early in life, long before children start to visit fast food shops. If children
are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat,
they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to
school. When they get home, they sit in front of the television or their computers and play computer games. Not
only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food. What they need is
to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be
more active, as well as steering them away from fast food shops and bad eating habits.
B. Those who often watch television.
C. Those who often have meals at home.
D. Those who often walk to school.
B. they are too busy to go out and play
C. they can"t choose what to eat
D. there are too many fast food shops around
B. guiding
C. driving
D. moving
B. provide facts
C. give advice
D. compare opinions
and cut waste-a step that environmentalists believe is a first for Europe.
Shopkeepers in Mod bury population 1,500, agreed to stop handing out disposable plastic bags to
customers on Saturday. They said paper sacks and cloth carrier bags would be offered instead.
Last month, San Franciso became the first U.S. city to ban plastic grocery bags. Internationally, laws
to discourage the use of plastic bags have been passed in parts of South Africa and Ireland, where
governments either tax shoppers who use them or fine companies that hand them out. Bangladesh already
bans them, and so do at least 30 remote Alaskan villages.
Mod bury, about 225 miles southwest of London, has also declared a bag ammesty (宽限期), allowing
local people to hand in plastic bags that have piled up at home. They will be sent for a recveling. The Mod
bury ban was the idea of Rebecca Hosking, who saw the effect of bags on manne life while working in the
Pacific as a wildlife camerawoman. She said response (反应) in the town so far had been "really positive".
"Mod bury is quite an old-fashioned town and a lot of people have wicker baskets to go out shopping
anyway," Hosking told Sky News Television.
The World watch Institute, an environmental research agency, states that 100 billion plastic bags are
thrown away each year in the United States alone. More than 500 billion are used yearly around the world.

C. A sailor.
D. A photographer.
