BUKHANNON, West Virginia—Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident.
Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates(最新报道)on the rescuers’ progress.
The miners were trapped at about 6:30 and many families weren’t informed of the accident until about 10 a.m-more than three hours after it happened. “It’s very upsetting, but you’ve got to be patient, I guess,” said John Helms, whose brother, Terry, was trapped in the mine.
The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine’s entrance, said Roger Nicholson, general counsel from International Coal Group.
At a late night news conference, Nicholson said one team had advanced about 4,800 feet in the four hours since entering the mine just before 6 p.m. Another team entered the mine about 30 minutes later.
He said the crew was very experienced, with some members having worked underground for 30 to 35 years. The miners were equipped with about one hour of breathable oxygen each. The company has not released the names of the miners.
The teams test the air about every 500 feet, and have to disconnect (remove) the power to the phones they use to communicate with the surface before doing that. “We don’t want to be energizing anything if it’s in an atmosphere with burnable gases,” Kips said. The cause of the explosion was not immediately known. High levels of carbon monoxide were detected shortly after the explosion, which delayed rescue efforts, but those levels have since subsided(减退), authorities said.
53. According to the passage, we can infer that ______.
A. all the miners who were trapped underground were still alive
B. communication with the trapped miners was cut off
C. the two rescue teams entered the mine at the same time
D. the rescue started as soon as the accident happened
54. If the first team advanced at an average speed, they could dig about ______ per hour.
A. 1,000 feet          B. 2,400 feet            C. 1,200 feet                D. 4,800 feet
55. Where can the passage be seen?
A. In a magazine.                                  B. In a newspaper.       
C. In a science book..                           D. On an advertisement.
56. Which of the following shows the position where the miners were trapped?

All over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer.

Sports change with the season. People play different games in winter and summer.

Games and sports often grow out of people’s work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too.

Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers.

Some sports or games go back to thousands of years, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time.

People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person’s character(性格). One learns to fight hard but fight fair, to win without pride and to lose with grace(体面)

A listener has written from China for advice about how to lose weight. Michael in Shanghai says he is 26 and has fought against obesity (过度肥胖) for most of his life.

Obesity , a severe weight problem, is a complex (复杂的) condition. A doctor may advise taking medicine along with changing one’s the way that he or she behaves. Experts say that the most successful weight—loss plans include a well-balanced diet and exercise.

People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use. To lose weight, you can reduce the number of calories you absorb (吸收), increase the number you use, or both.

A recent study looked at four of the most popular dieting plans in the US. Researchers at Stanford University in California studied over 300 overweight women, mostly in their thirties and forties. Each woman went on one of the four plans: Atkins, The Zone, Ornish or LEARN. The women attended diet classes and received written information about the food plans.

At the end of the year, the women on the Atkins diet had lost the most, more than four and one-half kilograms on average. They also did better on tests for cholesterol levels and blood pressure.

Christopher Gardner, who led the study, says the Atkins diet may be more successful because of its simple message to eat less sugar. He also says that the advice to increase protein in the diet leads to more satisfying meals. He says that there was not enough money to study men, but that men would probably have similar results.

Last week, another report based on thirty-one studies suggested that only a small number of people have long-term success with dieting. Most dieters regained (重新获得) their lost weight within five years and often they become more overweight ( 超重的). But those who kept the weight off generally were the ones who exercised.

SECTION B

Directions: Read the following passage. Answer the questions according to the in­formation given in the passage and the required words limit. Write your answers on your answer sheet.

Fast food and too much TV time should not take all the blame for the weight problems. A group of researchers say that a number of aspects of modern living from lack of sleep to environmental chemicals and to living with air conditioning ——may be closely related to the weight problems of many people.

Lack of sleep is one of factors. Research in animals and humans suggest that a lack of sleep over a long time can increase appetite. Studies also show that many adults and children are sleeping less than they used to. In recent decades, adults have gone from sleeping for all average of nine hours to about seven hours.

There is also evidence that industrial chemicals may increase body fat. These chemicals, which are used in products, change hormonal activity when they get into the body. Studies suggest that people have been getting more and more of these chemicals through the food chain in recent decades.

Another factor that may be making people overweight is air conditioning . The body burns calories when forced to eat less in hot and wet weather, but air conditioning makes it unnecessary for the body to make any adjustment.

Researchers also list other possible risk factors for overweight , including more older mothers, whose children may become overweight more easily; a number of medicines which can lead to weight gain ; and fewer people who smoke, since people often gain weight when they stop smoking because nicotine can make people eat less.

No one is suggesting that people should stop working and sleep more, or keep smoking. When it comes to any person's weight, what really matters is how much they eat and how much of the food they use every day. That means diet and exercise are still the key.

Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a turn of a switch.

“It took us a long time to figure out what a window really is,” says Claes Granqvist, a professor of solid—state physics at Uppsala University in Sweden.“It’s contact with the outside world. You have to have visual contact with the surrounding world to feel well.” So, windows and natural light are important for improving the way people feel when they’re stuck indoors.

Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it’s hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world.

Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use some technologies involving changes of color.

Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers(层) of tungsten oxide(氧化钨) works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage(电压) is decreased, the window darkens until it’s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark.

One important feature that makes a smart window so smart is that it has a sort of “memory”. All it takes is a small shock of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need.“In the future,” Granqvist says,“our buildings may look different.”

67.Which statement does not indicate the importance of windows as described in the first two paragraphs?

A.Windows can change from clear to dark to save energy.

B.Windows help to save energy by letting light in.

C.Windows help to save energy by providing heat.

D.Windows enable people to have contact with the outside world.

68.According to the passage, smart windows are windows_______.

A.that are coated                        B.that use electricity

C.the color of which can be changed        D.that have many layers

69.To make electrochromic windows change color, what is applied to the window glass?

A.Electricity.     B.Tungsten oxide.    C.A battery.         D.A voltage.

70.What will be the benefit if the research on smart windows turns out to be successful?

A.The buildings will look different.

B.Windows can be as large as you want.

C.We may not need air conditioners any more.

D.They are less expensive than traditional windows.
