This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories. A calorie is the amount of heat required to raise
the temperature of 1 kg of water by 1℃. The number of calories people need per day is different. Also, the
number of calories you use at any one moment normally depends on the activity you are in.For example, you
need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials-carbohydrate (碳水化合物), protein
(蛋白质) and fat. Carbohydrate provides 3.8 Cal/gm, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food
contains different amount of these materials, as the round pictures show.
_____.
B. rice
C. peanuts
D. rice or peanuts
B. Food contains energy in the form of carbohydrates, proteins and fuel.
C. Different people need different amounts of energy depending on their age, sex and the activities they are in.
D. 3 grams of milk provides 16.6 calories because carbohydrate provides 3.8 Cal/gm, protein 4.0 Cal/gm and
fat 8.8 Cal/gm.
B. the human body needs energy
C. the number of calories depends on your activity
D. we must only eat peanuts to get calories

Dr Aubrey de Grey thinks that we can stop people getting old and that in about 20 years, people will
be able to live to be 1,000 years old! 2_____
In Dr Grey"s opinion, getting old is a problem that can be solved. 3_____ If we can cure this disease,
we can stop the aging process. We can also make people have young bodies again.
Dr Grey believes that science will soon be able to stop the causes of aging so that a person"s body
won"t get weak and won"t suffer from the typical diseases of old age.
Dr Grey compares the human body to a house. As the house gets older, some things must be repaired.
Broken hearts must be replaced. The same thing can happen with the human body, he thinks. We can use
stem cell technology to grow new, healthy tissue to replace the old, damaged one. We can also try to remove
disease-causing molecules in our bodies. 4_____.
5_____ However, they admit that Dr Grey"s ideas have not yet been proved wrong. Dr Grey is convinced
that his opinions are realistic and that his research is very important. If aging is a disease, he says, we must
try to cure it.
B. Scientists succeed in solving the problem of aging long ago.
C. A lot of scientists think his ideas not realistic.
D. When our bodies change as we get older, this is like a disease.
E. New deadly diseases may also be cured, if we can stop the aging process.
F. It seems that everybody must get old and die.
G. In this way, a person could easily live to be 1,000 years old.
may not drive every day but still want a car to run errands (差事) or drive on weekends benefit most from car
sharing. Car sharing is usually run by a service like Zipcar, though there are non-profit (非营利的) and
informal car sharing services. Members pay a monthly fee and have access to an entire fleet of cars when they
need one. The cars are parked in fixed spots around the city, so members only need to make a reservation, and
then go to the pickup spot.
Car sharing has major environmental benefits because it reduces the number of cars on the road. Members
don"t drive just because they are in a car. They plan trips, and if they don"t need a car, they don"t use one. Still,
a car is available to them if they need to make a big trip to the grocery store, pick someone up at the airport or
if they want to go to the beach for the day. Members also benefit by having access to a car without any of the
headaches of ownership. They usually don"t have to pay for the gas, insurance or maintenance (保养), and the
monthly membership fee is less than a typical car payment. So if you really want to go green but aren"t ready to
totally give up a car yet, car sharing may be the way to go.
If you still need to get around, but want to go even greener than sharing a car, share a bus!
B. has become the best way to cut living costs
C. is becoming more and more popular in cities
D. is becoming popular both in urban and rural (乡村的) areas
B. Zipcar, different from other services, aims green driving with no profit
C. Zipcar is a company supplying car sharing service for a monthly payment
D. Zipcar is a company providing formal car sharing free
B. why car sharing benefits the environment
C. why car sharing is cheaper than owning a car
D. why a car is available to members
B. Car sharing can save you the headaches of ownership.
C. Bus sharing is even greener than car sharing.
D. Zipcar is the largest company offering car sharing services.
in order to reduce household carbon dioxide emissions.
The Morning Challenge campaign, made public by the Environment Ministry, is based on the premise (前提)
that exchanging late night electricity for an extra hour of morning sunlight could significantly cut the nation"s
carbon footprint.
A typical family can reduce its carbon dioxide footprint by 85kg a year if everyone goes to bed and gets up
one hour earlier, according to the campaign.
The amount of carbon dioxide emissions potentially saved from going to bed an hour early was the
equivalent of 20 percent of annual emissions from household lights, "Many Japanese people waste electric
power at night time, for example by watching TV until very late," a ministry spokesperson told The Daily
Telegraph.
"But going to bed early and getting up early can avoid wasting electrical power which causes carbon
dioxide emissions. If people change their lifestyle, we can save energy and reduce emissions." The campaign
also proposes that people take advantage of an extra hour of morning sunlight by improving their lifestyles in
general by running, doing yoga and eating a nutritious breakfast.
It is the latest measure dealing with climate change by the Japanese Environment Ministry, which is faced
with the challenge of reducing carbon dioxide emissions by 25 per cent from 1990 levels within the next
decade.
It was the same government department that started the high profile (姿态) Cool Biz campaign five years
ago, which encourages workers to wear short-sleeved shirts and offices not to turn air con lower than 28
degrees during the summer.
B. To encourage people to watch less TV.
C. To reduce household carbon dioxide emissions.
D. To show the sense of responsibility of the Japanese government.
the 1990 levels.

C. The Japanese Environment Ministry is responsible for climate change.
D. The purpose of Cool Biz campaign is similar to that of the Morning Challenge.
they might see a shocking photo of a blackened lung or a cancer patient staring back at them from the packet.
Some boys may think of smoking as cool and sexy. Their friends won"t agree when they see their packets
of cigarettes lying on the table. The European Union announced on October 22, that it had chosen 42 photos
that showed the damage cigarettes could do to the body. It called on member nations to put these pictures on
packets to discourage young smokers. To catch the attention of teenagers, the special packets warn of
long-term medical dangers, like cancer. Short-term effects, like bad skin, are also on the list.
"The true fact of smoking is disease, death and horror. That is the message we should send to the young,"
said David Byrne, an EU health official. "Hopefully these pictures will shock students out of their love for
cigarettes."
The EU head office hoped the pictures would work better than current written warnings on packs of
cigarettes. The warning included "smoking kills" and "smoking can lead to a slow and painful death."
So far, Ireland and Belgium have shown interest in the photos. Canada has used similar pictures and
warnings on cigarette packs since 2000. The country has recently seen a fall in the number of smokers.
According to studies, smoking is the single biggest cause of avoidable death in EU. Every year more than
650,000 smokers die, more than one person a minute.
B. Pictures to Shock Smokers.
C. New Packers of Cigarettes.
D. Dangers of Smoking.

A grizzly bear hunts for fish in a North American river. A mother blue whale and her calf glide through the
deep waters of the ocean.
All of these animals share the Earth with us. They fascinate us with their beauty, their grace, and their
speed. We love observing their behavior, and learning more about their habits. But just loving them is not
enough. All of these animals are endangered. Many of them have died, and without special care, they may
someday disappear from the Earth.
Why is it important to care for animals like these?One reason is to protect the balance of life on Earth.
Another reason is the beauty of the animals themselves. Each species of animal is special. Africa was once
filled with an abundance of wild animals. But that is changing fast. One of these animals, the black rhinoceros,
lives on the plains of Africa. It has very poor eyesight and a very bad temper!Even though the black rhino is
powerful, and can be dangerous, its strength can"t always help it to escape hunters. Some people think that the
rhino"s horn has magical powers, and many hunters kill rhinos for their valuable horns. This has caused the
black rhino to be placed on the endangered species list.
The elephant seems to represent all that is strong and wild in Africa. It once had no natural enemies, but is
now endangered-killed for its ivory tusks.
The fastest land animal, the cheetah, also lives in Africa. It,too, is becoming extinct as people take over
more and more of the land that is the cheetah"s natural habitat.
Imagine Africa without the powerful rhino, the gentle, intelligent elephant, or the lightning quick cheetah.
Once they are gone, they are gone forever.
B. Gone forever
C. Help animals
D. Live or die
B. Because it has a horn.
C. Because it is believed that its horn has magical power.
D. Because people think it is powerful and dangerous.

C. Wherever people are careless about the land, there are endangered species.
D. The elephant seems to represent all that is strong and wild in Africa.
