Six Americans are working on a new highway. But this highway won't have any traffic．It's an "ice highway" to the South Pole.
The team has just finished a second year of work on the 1,020-mile highway. "The road is the greatest single footprint of activity we've seen in the Antarctic (南极洲)," said Alan Hemmings, an Australian environmentalist.
The highway will provide a new way for supplies to be trekked (拉, 搬) across the earth on tractor-pulled sleds (雪橇). This method will use a lot less fuel than an aircraft, the current (当前的) way that scientists and supplies reach the Amundsen-Scott Base, a U.S. research station in the South Pole. The highway will also allow for equipment that is too big for planes to carry to be brought to Antarctica．Even with these benefits, there is one disadvantage—a round trip on the road will be 30 days, compared to a few hours by plane.
Making this 20-foot-wide road isn't easy, and it takes a lot of time. The crew (工作队) has been working on the road for two summers, when it's warmer and easier to work with the ice. It probably won't be completed until 2006.
Crevasses (裂缝), or cracks, in the land often make the construction difficult. Crevasses are kind of like pot holes that form when surface ice is stretched．This can be very dangerous, especially when the crevasses are hidden under a layer (层) of snow and can't be seen.
"Last year it took us three months to go three miles across a crevasse field, full of dangerous, hidden crevasses," said the project's manager, John Wright. Each year, more crevasses appear and they have to be filled with snow and ice so the road is safe for travel. The road will also be lined with green flags so travelers know where the safe surface is.
It will probably take ______ years to complete the ice highway.
A．2 B．4 C．6 D．8
When it is finished, the highway will not be used for ______.
A．giving supplies to the research station in the South Pole
B．taking scientists to the South Pole
C．taking travelers to a tour of Antarctic
D．bringing huge equipment to Antarctic
How many miles can be covered at most each day if you take the ice highway to the South
Pole?
A．30. B．34. C．68. D．88.
Which of the following is true according to the passage?
A．Other crevasses won’t appear if a crevasse has been filled.
B．Many new crevasses will form after a crevasse has been filled.
C．Travelers can drive their sleds on the ice highway freely.
D．There will be less danger if the crevasses are covered by snow.
Doctors Say Most Heart Disease Preventable
Heart disease is the number one killer, worldwide, of men and women over the age of 60. But people of all ages die of heart attacks each year. And while death rates have declined in the U.S. and many western European countries, they are on the rise in the developing world. 1. .
No one would have guessed that Barbara Teng would have a heart attack. She was not overweight. She did not smoke or exercise.“In 2004, the week after I turned 49, when I was on a business trip in Chicago, I had a major heart attack," she said. 2. . She now exercises daily, and monitors her heart health.
Dr. Patrice Nickens, who is with the National Heart, Lung and Blood Institute, thinks that heart disease is 82 percent preventable. “3. ,” she said, “Men are also facing the same problem, and the key to staying healthy is knowing your numbers”.
“Your weight, your blood cholesterol, blood sugar and your blood pressure are important numbers that can help you take action and reduce your risk,” she said.
4. .
“And the steps to take are simple: don’t smoke, maintain a healthy weight, exercise, know your numbers and talk to your physician and control these risks,” she said.
African-Americans are at higher-than-average risk for heart disease and stroke; people don't even know they have it, which increases the risk. Medstar Washington Hospital Center is trying to reach this population. 5. . For example, helping the people monitor their blood pressure. If people realize they are at risk for heart disease, they'll make lifestyle changes: lose weight, exercise, eat the right foods and keep in touch with a doctor
A. A healthy lifestyle can prevent heart disease
B. So we must cure heart disease
C. It is the leading cause of death for women
D. With the right training, they can play an important role in community health
E. And that changed her life
F. Lack of exercise causes heart attacks
G. Yet most heart disease is preventable.
“Drink your milk. It’s good for you!” You’ve probably heard that many times, and it’s true. Milk contains calcium, which is a necessary nutrient for keeping bones and teeth healthy and strong. The U.S. government even requires milk as part of the National School Lunch Program, saying that students should drink one cup of fat-free or low-fat milk at each meal.
Last Thursday, however, a group of doctors asked the government to remove milk from the lunch program. The Physicians Committee for Responsible Medicine (PCRM) says, “Milk is high in sugar, high in fat and high in animal protein, all of which have negative effects on health.” “One of the only reasons people talk about dairy, or promote it, is that it is going to help build strong bones.” says Dr. Neal Barnard, president of the PCRM. There are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient.
Of course, calcium is important for healthy bones and teeth, but your genes, how much vitamin D you take in and getting an hour’s worth of exercise every day all play a part.
Some nutritionists disagree with the idea that milk isn’t important. Keri Gans, a dietitian, says, “I think it’s irresponsible to take away this beverage that children enjoy, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line.”
The U.S. government is studying the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor at New York University, puts it best: “Milk has nutrients. Other foods have the same nutrients. It’s just a food. Like other foods, too much might be a problem.”
1.What is mainly talked about in the first paragraph?
A．The concern about students’ health. B．Traditional attitudes towards milk.
C．Ways to keep bones and teeth healthy. D．The practice of the U.S. government.
2.According to Dr. Neal Barnard, milk is preferred mainly because _____.
A．children like its taste B．people ignore its disadvantages
C．it contains more calcium than other foods D．the calcium in it can build up bone strength
3.We can learn from the text that _____.
A．bone strength is determined by many factors
B．people’s diets shouldn’t contain animal protein
C．the opinion of the PCRM will soon be accepted
D．people should turn to vegetables for calcium

Our bodies are wonderfully skillful at keeping balance．When the temperature jumps, we sweat to cool down．When our blood pressure falls, our hearts can do something．As it turns out, though, our natural state is always changing．Researchers are finding that everything from blood pressure to brain function changes regularly with the cycles of sun, moon and seasons．And their insights （洞察力） are getting new ways for keeping away such common killers as heart disease and cancer．Only one doctor in 20 has a good knowledge of the scientific use of time in medicine．But according to a new American Medical Association, three out of four are eager to change that．“The field is exploding,” says Michael Smolensky．“Doctors used to look at us like, What spaceship did you get off ? Now they're thirsty to know more．”
In medical school, most doctors learn that people with chronic conditions should take their medicine regularly．“It’s a terrible way to treat disease,” says Dr Richard Martin．For example, asthmatics （气喘患者） are most likely to suffer during the night．Yet most patients try to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler （吸入器） four times a day or taking a pill each morning and evening．In recent studies, researchers have found that a large mid afternoon dose of a bronchodilator （支气管扩张剂） can be as safe as several small doses, and better for preventing nighttime attacks．
If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease．Heart attacks are twice as common at 9 a．m．as at 11 p．m．Part of the reason is that our blood pressure falls at night, then rises as we start to work for the day．“Doctors know that,” says Dr．Henry Black of Chicago's Medical Center, “but until now, we haven't been able to do anything about it．” Most blood - pressure drugs provide 18 to 20 hours of relief （减缓）．But because they’re taken in the morning, they're least effective when most needed．“You take your pill at 7 and it's working by 9,” says Dr．William White of the University of Connecticut Health Center “But by that time you've gone through the worst four hours of the day with no protection．” Bedtime medicine would prevent high blood pressure, but it would also push blood pressure to dangerously low levels during the night．
