have sleeping problems a few nights each week, according to a recent study by the National Sleep
Foundation. Sleeping too little can lead to a higher risk of becoming fat and getting depressed(沮丧的).
But before you go to a doctor for advice, it is worth examining your sleeping habits one more time. Some
of your favorite evening habits may have something to do with the sleeping problems.
1.Setting a Bright Alarm Clock.
The light of your bright alarm clock can prevent you from falling asleep. You can make your room as
dark as possible. Cover the bright numbers with a book or consider buying a small travel clock. Your
cellphone alarm may also do the trick.
2.Counting Sheep
When you just can"t fall asleep, it"s useless to stay in bed to count sheep. If you"ve been trying to fall
asleep for more than 30 minutes, the National Sleep Foundation suggests you get up to do some reading or watch TV for a while. Such activities will make you sleepy. Before you know it, you"ll be going back to
bed really tired.
3. Exercising Late at Night
Daytime workouts(锻炼) will keep you full of energy for hours. That"s why you don"t want to exercise within three hours of hitting the sack. Fierce(剧烈的)physical activity raise your body temperature and
pumps your energy level-both are bad for a good night"s sleep.

sity of Warwick has built what it calls the world"s first completely environmentally friendly Formula Three racing car.
The car is made mainly of renewable materials, like plants and vegetables.The structure around the car is made from natural plant fibers and potatoes.The steering wheel (方向盘) is made from root ve
getables like carrots.The engine uses biofuel made from vegetable oil and waste chocolate.The new racing car is extremely fast.The car has a top speed of two hundred fifteen kilometers an hour.And it can go from zero to ninetyfive kilometers an hour in just two and a half seconds.The racing car
meets all of the Formula Three racing requirements except for its biodiesel(生物柴油) engine.
Automobile racing is one of the most widely watched sports in the world.But it is also considered one
of the least friendly sports to the environment.Racing car
s burn a lot of fuel, and create a lot of air pollution.In recent years, the racing industry has taken steps to protect the environment.More racing compan
ies are now producing cars that use less energy.These cars produce less pollution than cars that depend on traditional fuel, like gasoline.
Last month, the new racing car was set to run in its first competitive race at the Formula Three
Championship Final at Brands Hatch.It would have been the first biodieselpowered car to
race at Formula Three.Current Formula Three rules let only gasolinepowered car to compete.Officials needed permission from all of the Formula Three racers for the biodieselpowered car to compete.They were unable to contact one of the drivers, so the new racing car didn"t appear in the event.In test runs, the new racing car was the fifth fastest among the Formula Three race cars.Supporters are hopin
g to have the fuel problem solved in time to compete in the next season.
A. What materials the new racing car is made of.
B. Why researchers built the new racing car.
C. The characteristics of the new racing car.
D. The process of the new racing car being designed.

4. In recent years, racing companies are producing cars that ________.
A. burn more fuel
B. go more quickly
C. produce less pollution
D. cost less money
own carbon footprints(碳排放量), says Ryan Brook, a researcher who regularly flies north to study the
health of caribous (驯鹿). He calls on scientists to show leadership by examining and sharing ways to
reduce the impact of working in polar regions.
"The importance of the research is not at question here. It is important to our understanding of and
adapting to climate change. But we need to think about better approaches." says Brook.
"This is an issue for all scientists, though polar researchers often travel particularly long distances
using commercial air travel. We also rely extensively on small aircraft, icebreakers, and snowmobiles, all
of which produce large amounts of carbon. "
Brook studies the health of caribous herds in Nunavut and Northwest Territories. He works with
northern wildlife managers. This work typically takes him north five or six times per year and when he
calculated his own carbon footprint, he was not happy with the result.
"My research footprints are about the same as the annual footprints of an average Toronto resident.
Basically, I have two footprints-my own personal life, which is moderate, and my research footprint."
Climate scientists can rightly argue that Arctic research is a specialized field and the community of
scientists who travel north is relatively small. Even if all scientists working in the north reduced their
carbon emissions, it would not make a big impact on the global scale. For Brook, it"s the option that
matters.
There are ways researchers can reduce the amount of carbon they use. Some helicopters use less
fuel than others. Solar and wind power are alternatives to gasfired generators. And while carbon offsets
(抵消) don"t reduce the amount of carbon emitted, they ar
e an easy first step. "There aren"t necessarily any easy answers, but we need to start talking about it." says Brook. "This is
particularly important for the next generation of scientists being trained and I hope to see them become
leaders in this issue."
B. the study of the health of caribous
C. the impact of working in polar regions
D. the reduction of polar scientists" carbon emissions
B. His personal life footprints are more than the annual footprints of a Toronto resident.
C. His research footprints are about the same as his personal life footprints.
D. His personal life footprints are more than his research footprints.
B. the Arctic is a special environment
C. the footprints of Arctic scientists are small
D. Brook"s situation is not a common phenomenon
B. it"s easy to start talking about the problem of carbon emissions
C. it"s necessary now to pay attention to the problem of research footprints
D. the next generation of scientists are more interested in research footprints

| As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease－especially in changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought about this shift can be pursued further. Imagine a person who is about the right weight, but does  not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier. The field of medicine has not traditionally distinguished between someone who is just "not ill" and someone who is in excellent health and pays attention to the body"s special needs. Both types have simply been called "well". In recent years, however, some health specialists have begun to apply the terms "well" and "wellness" only to those who are actively attempting to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body"s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be "well", in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. "Wellness" may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can struggle for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial influence on the ways in which people face the challenges of daily life. |

| A. Wellness is now just an ideal in many people"s mind. B. Someone who drinks a few beers at home most nights is not healthy. C. The concept of wellness can help people face the challenges of daily life. D. A man without any physical or mental problem may not be really healthy. |
| 4. According to the author, healthy people are those who . |
| A. do not have any symptoms of disease B. have strong muscles as well as slim figures C. try to keep healthy as possible, regardless of their limitations D. can recover from illness even without seeking medical care |
