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. |
| 1. Today"s medical care is placing more stress on . |
| A. monitoring patients" body functions B. removing people"s bad living habits C. ensuring people"s psychological well-being D. keeping people in a healthy physical condition |
| 2. Traditionally, a person is considered "well" if he or she . |
| A. is free from any kind of disease B. does not have any physical handicaps C. attempts to maintain the best possible health D. keeps a proper balance between work and leisure |
| 3. According to the passage, which of the following is WRONG? |
| 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 |

| Winter depression ( or winter blues ) is a common affliction (折磨) for those who live in our northern climate.Its clinical name is seasonal affective disorder(or SAD)and up to 5% of the population (especially in northern states)may suffer from it.Seasonal affective disorder is characterized by feelings of sadness and depression that occur in the winter months when the temperatures drop and the days grow short.The depression is often associated with excessive eating or sleeping and weight gain.Women are twice to three times more likely to suffer from the winter blues than men. There are many effective treatments for winter depression, some of which you c  an do to help yourself.Increasing your daily exposure to as much natural light as possible can be helpful to many.Any time when you have the opportunity to gain access to more sunlight in the winter months, you should try to do so. Taking walks throughout the day( even if you don"t normally do so) , sitting next to a southfacing window at your office, in a classroom, or at home will increase your sunlight exposure.Exercising next to a window or outdoors (when possible) is another activity that can help. Although it may be difficult to do, maintaining your schedule and lifestyle will help to keep_the_ depression_at_bay.A regular pattern of sleep is the most important thing to maintain.It may be helpful, for instance, to have your bedroom lights on a timer to turn on a halfhour before you wake.This may help in waking at a regular time every morning,when it is still dark outside in the winter months. Light therapy has shown to be an effective treatment for seasonal affective disorder.While you can purchase expensive, specialized light therapy lighting fixtures for your home or office, some inexpensive alternatives are also available.Another lighting technique to try is to replace commonly used light bulbs in your home with brighter full spectrum( also known as broad spectrum)light bulbs.While more expensive than regular light bulbs, these bulbs provide light that is similar to natural sunlight. If none of these techniques seem to help your depressive symptoms, you should consider consulting your family physician or a mental health professional.The winter blues are a form of depression and can be readily treated with medications or psychotherapy when other selfhelp methods aren"t effective.Don"t be afraid to talk about this condition with a professional；it"s nothing to be ashamed or afraid of.With a little effort, the winter blues can be beaten. |
| 1. What do we know about winter depression? A. It is very common where the weather is cold. B. It may lead to weight gain. C. It occurs when the temperatures drop. D. It seldom affects men. 2. What is the most important factor in the therapy introduced in the second paragraph? A. Exposure to natural light. B. Sports in winter months. C. Outdoor activities. D. Sunlight through the window. 3. What does" to keep the depression at bay" mean in the third paragraph? A. To shorten the duration of the depression. B. To use light to resist the depression. C. To keep the depression manageable and minimal. D. To delay the occurrence of the depression. 4. For winter depression,light therapy________. A. is much more effective than other kinds of therapy B. is so expensive that some may not be able to afford it C. encourages people to do outdoor exercises D. needs specialized bulbs to replace ordinary ones |

The koala, one of Australia"s most treasured creatures, is in trouble. Affected by habitat (栖居地) loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population, that is worrying many scientists about the fate of the koala. The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected (感染) but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food. Treating Chlamydia in wild koalas is a challenge. There is no treatment available for it. Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala; it is up to each region to make management plans for its koala population. The good news is that researchers are working to test a vaccine (疫苗) that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccine more widely. But it"s impossible to vaccinate (给注射疫苗) all wild koalas. Another possibility would be to make vaccine distribution a routine part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs. While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may be enough time to give researchers a chance to solve some of the other problems facing Austalia"s koalas. |
| 1. Which isn"t considered the main cause of koala"s population decline? A. A deadly disease. B. Injuries from cars and dogs. C. Climate change. D. Habitat loss. 2. The third paragraph mainly tells us_____. A. the serious result Chlamydia has caused to the koala B. Chlamydia affected the koala only in particular regions C. the most serious symptom of Chlamydia is eye infections D. Chlamydia can seriously affect koala"s primary food 3. We can learn from the text that the vaccine_____. A. would cure the killer Chlamydia quite effectively B. would only be distributed in koala care centers C. has already been put into practical use in Australia D. cannot be distributed to all the infected koalas 4. It can be inferred from the text that_____. A. a national plan for saving koalas will be made soon in Australia B. koala population is declining only in a few regions C. researchers need enough time to solve the koala problems D. experts have lost the best chance to save the infected koalas |
