People who are outdoors in cold weather should avoid actions like suddenly lifting a heavy basket full of snow. Even walking through heavy, wet snow can strain a person’s heart.
Many people aren’t conditioned to the physical stress of outdoor activities and don’t know the dangers of being outdoors in cold weather. Those who like winter sports can suffer accidental hypothermia if they don’t make certain preparations.
Hypothermia means the body temperature has fallen below normal. It occurs when your body can’t produce enough energy to keep the internal (内部的) body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia.
Children, the elderly and those with heart disease are at special risk. As people age, their ability to keep a normal internal body temperature often decreases. Elderly people can suffer hypothermia without knowing they’re in danger because they can’t notice the cold conditions as quickly as the young.
Besides cold temperatures, high winds, snow and rain can also steal body heat. Wind is especially dangerous because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 20-mile-per-hour wind, the cooling effect is equal to calm air at four degrees. Similarly dampness (湿气) causes the body to lose heat faster than it would at the same temperature in drier conditions.
To keep warm, wear more clothes. This traps air between layers. Also, wear a hat or head scarf. Much of your body’s heat can be lost through your head. Keep your hands and feet warm, too, as they tend to lose heat rapidly.
Don’t drink alcohol before going outdoors or when outside. Alcohol makes you feel warm at first because blood vessels in the skin expand. But heat is then drawn away from the body’s important organs.

Since the gene, called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging, immunity(免疫)and resistance in humans, the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,” said Robin May of the University of Birmingham, who led the study.
Populations across the world are aging at a surprising pace, bringing potentially big challenges for health and social care systems. A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays. Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.
“What we have found is that things like resistance and aging tend to go hand in hand,” May said in an interview.
May’s team compared longevity, stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAF-16 in each of the four species, and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes, which scientists believe play a role in the aging process.
“The fact that subtle（微妙的）differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution,” May said.

Poorer children would be offered the chance to attend lessons on Saturday to help catch up with their middleclass peers (同龄人), the shadow schools secretary, Michael Gove, said today.The Conservatives would give English state schools the freedom to choose to have longer teaching hours and extra classes at the weekend, he told the Association of Teachers and Lecturers’annual conference.
Gove said the move would help to close the achievement gap with richer children whose parents could afford extras such as tutoring and music lessons.
He told delegates (代表) in Manchester: “For children who come from homes where parents don’t have the resources to provide additional stretch and cultural experiences, there are benefits in having those children in the learning environment, in school, for longer.”
“Parents would love to have schools starting earlier in some circumstances, and certainly going on later in the afternoon, given the reality of their working lives,” he said. He held up the example of Kipp (Knowledge is Power Program) schools in the US, which are often based in the poorest communities and open from 7:30 am to 5pm on weekdays, plus Saturdays.
But it would be up to schools to decide to offer longer hours, Gove added.
Parents said Saturday classes could become a “badge of dishonor”if pupils were forced to go, while teachers raised concerns about their workload.
Margaret Morrissey, of Parents Outloud, said: “I think the suggestion the government made about one-to-one teaching for these kids would be a more preferable way of improving these children’s performance. I’m just not sure whether taking away a child at weekends is actually going to make them cleverer in the week.”
The ATL’s general secretary, Mary Bousted, said: “If we want Saturday schools, then we need more teachers doing the extra hours, not the same teachers working longer.”
66. The program is intended for children____________.
A. who are from middle-class families
B. whose parents can’t afford extra help
C. who perform poorly academically
D. whose weekends are mostly unoccupied
67. “Additional stretch” in Paragraph 4 probably refers to_________.
A. music lessons
B. physical relaxation
C. entertainment activities
D. out-of-school improvement
68. Why did Gove mention Kipp schools in the US?
A. To make a comparison.
B. To introduce a new program.
C. To seek supportive evidence.
D. To prove his program is better.
69. What is Margaret Morrissey’s opinion about the new program?
A. Favourable. B. Doubtful. C. Optimistic. D. Acceptable.
70. Which of the following is true?
A. Teachers may not like the program.
B. Schools are trying to make profits.
C. The program is already under way.
D. The program is popular with children.
Across the United States, there are several places where two independent towns grew together to become one city — but kept both their names. 
WinstonSalem is one of them. It’s a midsized city in what’s called the plateau（high land）, between the Atlantic Coast and the inland mountains in the state of North Carolina. The Winston part is a relatively new place, founded early this century. It’s home to the nation’s biggest openair tobacco market.
The giant R.J. Reynolds Tobacco Company’s headquarters is in WinstonSalem, and Winston is the name of one of Reynolds’bestknown cigarette brands. Fastgrowing Winston soon surrounded the much older town of Salem, so in 1913, people in the area voted to combine them into a single place.
From a historical and tourist point of view, Salem, or Old Salem, as it’s called today, is the interesting and unusual part of town.
Salem was founded in the 1700s by the Moravians. They spoke German, and their community was religiously based, with single men and single women living apart in separate dormitories. The Moravians greatly valued women’s work and brainpower. In fact, one of the nation’s oldest boarding schools for young women— the Moravians’Salem Academy founded in 1772 — is still in operation.
Over the years, Salem lost its Moravian character. That all changed, though, when a nonprofit group began to rehabilitate the historic area. These days Old Salem is what’s called a living history museum, with exhibits, music, and tours of 18th-century houses, taverns and Moravian dormitory buildings just seven blocks from the tallest skyscraper in Winston-Salem.
The historic community is booming again. Just as R. J. Reynolds is taking in millions of dollars making cigarettes across town, Old Salem is generating about S| 15 million a year in tourism revenue and donations.
61. From the passage we can know that____________.
A. Winston-Salem is the name of a city
B. Salem is home to the tobacco market
C. the city Winston-alem has two names
D. Old Salem is the name of a tobacco brand
62. It can be inferred from Paragraph 3 that__________.
A. the two cities benefited each other
B. Salem developed faster than Winston
C. R.J. Reynolds Company has moved into Salem
D. the combination meets the wishes of the people
63. The city Salem is special for its__________.
A. boarding school B. lifestyle and tradition
C. respect for brainpower D. religious belief
64. The underlined word “rehabilitate” in Paragraph 6 is closest in meaning to “_________”.A. reconstruct B. evaluate C. enlarge D. decorate
65. What will probably be talked about in the following part?
A. Some other attractions in Winston-Salem.
B. How Winston makes profits from tourism.
C. Other examples of cities combined by two parts.
D. Something about the boarding school for women.
In their book Time to Eat the Dog: The Real Guide to Sustainable Living, Robert and Brenda Vale say keeping a mediumsized dog has the same ecological impact as driving 10,000 km a year in a 4.6 liter Land Cruiser.
“We’re not actually saying it is time to eat the dog. We’ re just saying that we need to think about and know the ecological impact of some of the things we do and that we take for granted.”
Constructing and driving the jeep for a year requires 0.41 hectares of land, while growing and manufacturing a dog’s food takes about 0.84 hectares — or 1.1 hectares in the case of a large dog such as a German shepherd.
Convincing flesheating cats and dogs to go vegetarian for the sake of the planet is a nonstarter, the Vales say. Instead they recommend keeping “greener”, smaller, and more sustainable pets, such as goldfish, chickens or rabbits.
The book’s playful title, and serious suggestion that pet animals may be usefully “recycled”, by being eaten by their owners or turned into pet food when they die, may not appeal to animal fans.
Annoying as the idea may be, the question is valid given the planet’s growing population and limited resources, Robert Vale said.
“Issues about sustainability are increasingly becoming things that are going to require us to make choices which are as difficult as eating your dog. It’s not just about changing your light bulbs or taking a cloth bag to the supermarket,” he said.
“It’s about much more challenging and difficult issues,” he added. “Once you see where cats and dogs fit in your overall balance of things, you might decide to have the cat but not also to have the two cars and the three bathrooms and be a meat eater yourself.”
56. The authors gave their book the playful title to________.
A. make it amusing B. create a vivid image
C. show writing skills D. arouse people’ s concern
57. In Paragraph 3 the writer mainly wants to tell us________.

B. the neglected ecological impact
C. some familiar examples
D. some actual figures
58. What does “sustainability” mean according to the passage?
A. Going vegetarian.
B. Raising cats and dogs.
C. Using a cloth bag.
D. Keeping a greener life.
59. Who may not like the idea of “recycling” pet animals?
A. Manufacturers.B. Drivers.
C. Animal fans. D. The authorities.
60. What do the authors think of living a sustainable life?
A. Challenging. B. Inspiring. C. Inviting. D. Touching.
When you are little, it’s not hard to believe you can changed the world. I remember my enthusiasm when, at the age of 12, I addressed the people at the Rio Earth Summit. “I am only a child,” I told them. "Yet I know that if all the money spent on war was spent on ending poverty and finding environmental answers, what a wonderful place this would be. In school you teach us not to fight with others, to work things out, to respect others, to clean up our mess, not to hurt other creatures, to share, not be greedy. Then why do you go out and do the things you tell us not to do? You grownups say you love us, but I challenge you, please, to make your actions reflect your words."
I spoke for six minutes and received a standing ovation. Some of the delegates even cried. I thought that maybe I had reached some of them, that my speech might actually spur（刺激） action. Now, a decade from Rio, after I've sat through many more conferences, I'm not sure what has been accomplished. My confidence in the people in power and in the power of an individual's voice to reach them has been deeply shaken.
When I was little, the world was simple. But as a young adult, I'm learning that as we have to make choices--education, career, lifestyle--life gets more and more complicated. We are beginning to feel pressure to produce and be successful. We are learning a shortsighted way of looking at the future, focusing on four-year government terms and quarterly business reports. We are taught that economic growth is progress, but we aren't taught how to pursue a happy, healthy or sustainable way of living. And we are learning that what we wanted for our future when we were 12 was idealistic and naïve（天真）.
Today I'm no longer a child, but I'm worried about what kind of environment my children will grow up in. I know change is possible, because I am changing, still figuring out what I think. I am still deciding how to live my life. The challenges are great, but if we accept individual responsibility and make choices, we will rise to the challenges, and we will become part of the positive tide of the change. I hope this goal will be met through our common efforts. Thank you all.
