Alaskan black bears hibernate for up to seven months a year, during which time they do not eat or drink, before waking up in virtually the same physical state they fell asleep in.
Now experts hope to develop methods of putting humans into a similar state which could help astronauts survive long missions and lead to new ways of treating severely ill patients.
While many studies have examined hibernation in mice and hedgehogs, little research has been done into the same condition in larger mammals such as bears.
But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the animals' body temperature, heart rate and muscle movements while they slept.
The research results showed that during a five-month hibernation the bears’ body temeratures varied between 30℃ and 36℃ in cycles that lasted between two and seven days—a pattern that was previously unknown in hibernating animals.
The research project leader said, "If our research could help by showing how to reduce metabolic(新陈代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply need to know how to turn things on and off to take advantage of the different levels of hibernation."
Craig Heller, of Stanford University, who contributed to the study, added: "There has always been a thought that, if there is ever long-distance space travel, it would be good to be able to put people into a state of lower metabolism or a state of hibernation. That's almost science fiction but you can see the logical basis."

Scientists have long understood the key role that oceans play in controlling the Earth’s climate. Oceans cover 70 per cent of the surface of the globe and store a thousand times more heat than the atmosphere does. What’s newer is the understanding of how this key component(组成部分) of our climate system responds to global warming.
A brake on global warming—for now
One of the oceans’ most important climate functions is absorbing heat and carbon dioxide(CO2), one of the gases that causes global warming. Acting as something absorbing heat, the oceans have absorbed huge amounts of heat and CO2 in the last forty years.
Fujita explains, “the oceans are saving us from faster climate change—they are putting a brake on the climate system.”
“That’s the good news,” he adds. “The bad news is that the oceans only slow the atmospheric warming. Once the oceans come to balance with a greenhouse-gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter.” But where and how the oceans release this slowly increased heat is uncertain. And as the ocean stores heat, fragile(脆弱的) underwater ecosystems are struggling.
The most recent scientific report from the Intergovernmental Panel on Climate Change(IPCC) also notes with concern that the ocean is acidifying(酸化) because of increased absorption of atmospheric CO2. and thus causing a threat to shell-forming species.  Sharp increase in CO2 levels will cause further acidification of the ocean.
Currents distributing heat
Another important role the oceans play is that of distributor(散布者). Oceans deliver heat and life-sustaining nutrition around the globe. Just as blood tube bring oxygen and nutrition to cells in the human body, the ocean’s currents carry oxygen, nutrients and heat throughout the Earth. The ocean distributes 25 to 50 per cent of energy the planet receives from the sun. For example, the Gulf Stream carries heat across the Atlantic. This warm current gives northwestern European a milder climate that it would normally have so far north. A change to the ocean’s circulation patterns could throw Europe into a colder period, even as the rest of the world is experiencing warmer temperatures.
小题1: We can infer from the passage that _______.
A.the oceans cause global warmingB.the oceans stop global warming
C.the oceans release nutrients and heatD.the ocean ecosystems face more dangers
小题2: From the passage we can learn that ocean’s currents _______.
  1. produce oxygen and nutrients around     
  2. absorb 25-50% of the energy from the sun
  3. distribute the atmosphere hotter        
D.  change the ocean’s circulation patterns
小题3: Which of the following are the results of the ocean absorbing heat and CO2?
a. It causes further acidification.        
b. It makes the atmosphere hotter.
c. It balances the oceans with a green-house gas. 
d. It affects shell-forming species.  
e. It makes the oceans act as a heat sponge.           
f. It controls the Earth’s climate.
A.a-c-fB.a-d-fC.b-d-eD.b-c-e
小题4: If the ocean’s circulation pattern changed, ______.
A.Asia would suffer a hotter climate.
B.Europe would become hotter
C.the rest of the world would become warmer.
D.the climate of Europe would become colder.

Most of the news in the newspapers is bad but sometimes there is a story with good news. This is one of those stories. Millions of people around the world suffer from AIDS, malaria, tuberculosis, and other serious diseases. There are medicines to treat these diseases but for people in poor countries, these medicines are too expensive to buy. When a pharmaceutical(制药的)company produces a new medicine, they receive a special license called a patent. This license means that the new medicine or drug is protected for a period of 20 years. The company that produced the drug can fix the price of the drug and no other company is allowed to produce the same drug or a copy of the drug for 20 years. At the moment, these patents operate all over the world, both in rich countries and in poor countries. The drugs companies say that they need patents so that they can get the money to pay for research to find new drugs and medicines. In rich countries people usually have enough money to pay for these drugs but in poor countries people can’t afford to buy them and cannot treat diseases like AIDS and malaria.
Last month, however, a group of experts published a report which says that patents are very bad for poor countries. The report says that drug companies do not want to find new medicines for diseases of poor people in poor countries. It says that poor countries should be allowed to buy cheap drugs without patents from other countries.
The authors of the report were lawyers, scientists and a senior director from the drug company Pfizer. Of course, the pharmaceuticals industry doesn’t agree with the report, “We need patents so that we can develop new medicines to fight disease both in the developed and developing world,” said a spokesman. But the report is the first sign that there might be a change in the patent system. This change could save millions of lives in the world’s poorest countries. This really is good news.
小题1: Why are medicines expensive for people in poor countries?
A.They are protected by patents.B.They are produced in rich countries.
C.They are imported.D.They can cure the deadly diseases.
小题2: What does the underlined word “patent” in Para1 mean in Chinese?
A.执照B.专利权C.专利品D.商标
小题3:Why do drugs companies need patents?
A.To sell drugs in rich countries.
B.To sell drugs in poor countries.
C.To get money to produce new drugs.
D.To compete with other companies.
小题4: What does the report say?
A.Poor countries should spend more money on drugs.
B.Poor countries shouldn’t obey a pharmaceutical patent.
C.Poor countries should import drugs.
D.Poor countries should be allowed to make copies of drugs.
小题5:What might happen if the patent system is changed?
A.Millions of lives will be saved in poor countries.
B.Drugs companies will stop producing drugs.
C.Drug companies will make more money.
D.The competition will be canceled.

When it comes to eating out, we can't help thinking of big meals in the restaurants, which usually contain much more fat and less fibers. Whether it is a business meeting over lunch or a fast food meal with the kids, eating out is a part of our lives. We eat out to save a lot of time, like grabbing a bite at fast food restaurants, or we take dining out as a favorite way to relax and socialize with friends.
Eating out can be fun but many people still like eating at home more because it is healthier. When my dear wife does not prepare foods for me, I would rather cook some instant noodles and eat at home! However, we go out to eat once in a while for holidays or on special occasions.
More and more people want to make healthy food choices nowadays. Some are watching calories, while others want to keep their cholesterol(胆固醇)under control or eat less fat. Plan ahead and choose wisely, you will find foods that fit into your meal plan and make eating out both healthy and enjoyable.
Here are some pointers to remember that can help you make wise choices when eating out: go for balance, watch portion sizes and drink water or low-fat milk. Keep the ground rules of good nutrition in mind. Eat a variety of foods in moderate(适中的)amounts, limit the amount of fat you eat, and watch the amount of salt in food. If you develop the skills to make healthy choices now, your body will thank you later.
Eating out can be one of life's great pleasures. Make the right choices, ask for what you need, and balance your meals out with healthy meals at home. You can enjoy yourself and take good care of yourself at the same time.
小题1: From the passage, we can infer that often eating out______________ .

There is a boy called Bill in my gym class who has unbearably yellow teeth that almost make everyone feel unpleasant.Recently another boy told Bill that he should "go Ajax" his teeth.Bill was crushed.If the other boy had been thinking, he would have realized that there is a better way to handle such a situation.He could have dealt with it with tact.He could have showed this hurtful truth in a more careful, sensitive way—that's "tact".
If a person isn't sensitive to another's feelings, there is no way he or she can be tactful.Yesterday, my 5-year-old brother proudly announced that he had cleaned the screen on our television set.Unfortunately, he used furniture polish, which produced an oily film on the television screen.My mother smiled arid thanked him for his efforts—and then showed how to clean the screen properly.Her sensitivity enables my brother to keep his self-respect.Yet, sensitivity alone does not make tact.
"Tactfulness" also requires "truthfulness".Doctors, for example must be truthful.If a patient has just been disabled in an accident, a tactful doctor will tell the truth—but express it with sensitivity.The doctor may try to give the patient hope by telling them curing techniques under study or about advanced equipment now available.Doctors must use tact with patients' relatives as well.Instead of bluntly saying, "Your husband is disabled," a doctor might say, "I'm sorry, but your husband has lost feeling in his legs and..."
Tact should not be confused with trickery.Trickery occurs when a nurse is about to give a patient an injection(注射) and says, "This won't hurt a bit." Instead of trickery, the nurse might guarantee the patient that the discomfort of the injection is a small thing compared to the benefits of it.It would also be thoughtful for the nurse to tell the patients about some of these benefits.
Tact is a wonderful skill to have, and tactful people are usually admired and respected.Without tact our society would become an intolerable place to live in.
小题1:The underlined word "crushed" in the first paragraph probably means____.
A.surprisedB.cheatedC.regretfulD.painful
小题2:According to the author, his mother's praise for the brother is ____.
A.sensitive and tactfulB.sensitive but not tactful enough
C.truthful but not tactful enoughD.sensitive but trickish
小题3:Which of the following shows the structure of the passage?

Butter is bad for you—so is margarine(人造黄油).Coffee raises blood pressure, but may protect against cancer.Alcohol is okay, but only if it's wine.The confusing studies on what is safe to eat and drink are enough to make it impossible for anyone to understand what "good food" is.
Take the margarine-butter debate for example.Studies that linked fat—found mostly in animal products such as meat and butter—with cancer and heart disease sent millions rushing to buy margarine.But then another study found that people who ate a lot of margarine also had high levels of heart disease.For those who have a firm faith in science, this seems to be the end of the world.
But many doctors point out that their advice has never been conflicting.For years, and in various countries, they have recommended eating less fat.
People in western countries such as Britain and the United States get about 40 percent of their calories from fat.Doctors say this should be around 30 or even 25 percent,
"We must try to reduce total fat," said Dr.Robert Richardson of the University of Edinburgh, who has been studying the effects of fat on human health for years.
"We need to go to more such food as bread, in particular brown bread, and more fruit and vegetables."
Fresh produce may not be so safe, either.Last month the British Government advised consumers to peel their pears before eating, while many Americans briefly avoided apples because of fears over an insect killing chemical.
But Dr.Arnold, a British scientist, said any risk of such poisoning would be outweighed by the costs of not eating plant foods.
"On balance, if you were to put both risks against each other, the advice has to be eating as much fruit and vegetable daily as possible," she said.
In general, doctors conclude, variety truly is the best policy."The general advice is pretty much the same advice that doctors have been talking about for a long time—a varied diet, a mixture of foods and not too much of any one," Arnold said.
小题1:In which section of the magazine are you most likely to find this passage?
A.Arts and CultureB.Entertainment
C.NatureD.Health
小题2:The British Government advised consumers to peel their pears before eating because ________.
A.it found that there were insects on the pears
B.it wanted consumers to avoid insect, killing chemicals
C.the skin of pears was found to be bad for people's health
D.it was a bad habit not to peel them
小题3:The underlined word "outweigh" (Para. 8) means " __________."
A.to be heavier than usual or allowedB.to be more dangerous than
C.to be greater in value or importance thanD.to be considered less important than
小题4:What can we infer from the passage?
A.Many doctors say that their advice has never been conflicting.
B.Science provides answers to all our questions.
C.We should peel our pears before eating.
D.We should eat plant foods despite the risk of poisoning.
