Computers
Before the widespread use of computers, managers could not make full use of large amounts of valuable information about a company's activities. The information either reached managers too late or was too expensive to be used. Today, managers are facing a wide range of data processing and information instruments. In place of a few financial controls, managers can draw on computer-based information systems to control activities in every area of their company. On any kinds of performance measures, the information provided by these systems helps managers compare standards with actual results, find out problems, and take corrective action before it is too late to make changes.
The introduction of computerized information systems has sharply changed management control in many companies. Even a neighborhood shopkeeper may now use computers to control sales, billing, and other activities. In large companies, electronic data processing systems monitor entire projects and sets of operations.
Now, there are about 24 million microcomputers in use in the United States —— one for every 10 citizens. It is estimated that by 1996, 61 percent of American managers will be using some sort of electronic work station. In order for managers to be sure that the computer-based information they are receiving is accurate, they need to understand how computers work. However, in most cases they do not need to learn how to program computers. Rather, managers should understand how computerized information systems work; how they are developed; their limitations and costs; and the manner in which information systems may be used. Such an understanding is not difficult to achieve.
One research found that business firms were more successful in teaching basic information about computers to business graduates than they were in teaching business subjects to computer science graduates.
16 Today, conventional financial controls are still exercised in some minor areas such as billing and vocational training.
A Right B Wrong C Not mentioned
17 It is unnecessary for a neighborhood baker to use a computer in his shop
A Right B Wrong C Not mentioned
18 At present about 10% of American citizens possess a microcomputer.
A Right B Wrong C Not mentioned
19 One thing that managers do not have to understand is how computers work.
A Right B Wrong C Not mentioned
20 In some cases managers have to learn how to write programs so as to work out computerized information systems that suit their own companies best.
A Right B Wrong C Not mentioned
21 Computerized firms would rather employ business graduates than computer science graduates because it is easier to train the former into qualified employees.
A Right B Wrong C Not mentioned

LED Lighting
An accidental discovery announced recently has taken LED lighting to a new level, suggesting it could soon offer a cheaper, longer-lasting alternative to the traditional light bulb. The breakthrough adds to a growing trend that is likely to eventually make Thomas Edison’s bright invention1 obsolete. LEDs are already used in traffic lights, flashlights, and architectural lighting. They are flexible and operate less expensively than traditional lighting.
Michael Bowers, a graduate student at Vanderbilt University, was just trying to make really small quantum dots, which are crystals generally only a few nanometers big. Quantum dots contain anywhere from 100 to 1,000 electrons. They’re easily excited bundles of energy, and the smaller they are, the more excited they get. Each dot in Bower’s particular batch was exceptionally small, containing only 33 or 34 pairs of atoms.
When you shine a light on quantum dots or apply electricity to them, they react by producing their own light, normally a bright, vibrant color. But when Bowers shined a laser on his batch of dots, something unexpected happened. He was surprised when a white glow covered the table. The quantum dots were supposed to emit blue light4, but instead they were giving off a beautiful white glow.
Then Bowers and another student got the idea to stir the dots into polyurethane and coat a blue LED light bulb with the mix. The lumpy bulb wasn’t pretty, but it produced white light similar to a regular light bulb.
LEDs produce twice as much light as a regular 60 watt bulb and burn for over 50.000 hours. The Department
of Energy estimates LED lighting could reduce U. S. energy consumption for lighting by 29 percent by 2025. LEDs don’t emit heat, so they’re also more energy efficient. And they’re much harder to break.
Quantum dot mixtures could be painted on just about anything and electrically excited to produce a rainbow of colors t including white. The main light source of the future will almost surely not be a bulb. It might be a table, a wall, or even a fork.
23. Paragraph 1_____
24. Paragraph 3_____
25. Paragraph 5_____
26. Paragraph 6_____
A. LED Lighting Is Not Mature
B. LED Lighting Will Replace Traditional Lighting
C. Almost Everything Could Be the Main Light Source in the Future

四、阅读理解。下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。
第一篇
Eat to Live
A meager diet may give you health and long life, but it’s not much fun — and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don’t start to diet until old age.
Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse’s liver genes can he made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won’t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.
Spindlers team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old — equivalent to about 70 human years.
The researchers checked the activity of 11, 000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production — probably bad news for mouse health. In the mice that had dieted nil their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes.
“This is the first indication that these effects kick in pretty quickly.” say Huber Warner from the National Institute on Aging near Washington D. C.
No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. “There’s attracting and tempting evidence out there that it will work,” he says.
If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective.
But Spindler isn’t sure the trade-off is worth it. “The mice get less disease, they live longer, but they’re hungry,” he says, “Even seeing what a diet does , it’s still hard to go to a restaurant and say: ‘I can only cat half of that’.”
Spindler hopes we soon won’t need to diet at all. His company, Lifespan Genetics in California, is looking for drugs that have the effects of caloric restriction.
31. According to the passage, which of the following is NOT true?
A. Eating less than usual might make us live longer.
B. we go on A diet when old, we may keep healthy.
C. Dieting might not be needed.
D. We have to begin dieting since childhood.

Snowflakes
You’ve probably heard that no two snowflakes are alike. Of course, nobody has ever confirmed that statement by examining every one of the estimated one septillion snowflakes that drift to Earth each year. Still, Kenneth Libbrecht, a professor at the California Institute of Technology, is confident that the statement is true.
Snowflakes aren’t flaky, says Libbrecht. At their basic level, they’re crystalline. The lattice of every snowflake is six-sided in shape. The simplest snow crystals are six-sided flat plates and six-sided columns. Such crystals are common in places where the air is extremely cold and dry. Snow crystals acquire their special beauty when their simple six-sided symmetry blossoms. Under the right conditions, each of the six corners of a crystal sprouts1 what is called an arm. In a matter of minutes, the arms can become highly ornate and give the crystal a star like appearance.
Several factors in the environment affect the shape and growth rate of a snow crystal. One factor is humidity. Crystals grow faster and in more intricate shape as humidity increases. A second factor is air temperature. A snowflake is born when several molecules of water vapor in a cloud land on a speck of dust and freeze to form a simple crystal. As the young crystal bops around in the cloud, it passes through air pockets of varying temperatures. If the crystal passes through a pocket of air that is, say, -15 degrees Celsius, it will grow quickly and sprout six arms says Libbrecht. If the crystal is then tossed into a warmer pocket, one about -100C, the arms tips will stop growing quickly and form six-sided plates. If the crystal then drifts into an even warmer pocket of about -50C, its top and bottom will grow more quickly than its sides and become more column like in shape.
In the course of its life span, a snow-crystal might flutter through many warmer and colder pockets, acquiring a complicated and unique growth history. Such a history will give rise to a snowflake that is unlike any other. Each arm on the snowflake will look exactly like every other one, but the crystal itself will be one of a kind.
Using his cooling tanks, Libbrecht has learned how to create snow crystals of different shapes - plates, columns, needles, etc. Libbrecht has even refined his techniques so that he can make crystals that look highly similar to one another. Still, he lacks the control to manufacture identical twin snowflakes. A slight difference in humidity and temperature can upset the growth profile of a crystal.
36. What does Professor Libbrecht believe to be true?
A. No two snowflakes are exactly the same in shape.
B. Somebody has examined all the snowflakes that fall on Earth.
C. The statement that no two snowflakes are alike is confirmed.
D. None of the above.
37. What do the simplest snow crystals look like?
A. They have six columns.
B. They are flaky.
C. They are cubic in shape.
D. They are six-sided.
38. What are the factors that affect the shape and growth rate of a snow crystal?
A. Humidity and temperature.
B. Water and falling speed.
C. Air and altitude.
D. Both B and C.
39. It can be felt from the description in the 2nd paragraph that the author
A. admires the beauty of the snowflakes.
B. dislikes the changing growth history of the snowflakes.
C. has a particular feeling for those flower-like crystals.
D. likes to compare snowflakes to the stars in the sky.
40. Libbrecht is not able to
A. create snow crystals of different shapes.
B. make crystals that look similar to one another.
C. create snowflakes that era exactly alike.
D. refine his techniques.

Ford Abandons Electric Vehicles
The Ford motor company’s abandonment of electric cars effectively signals the end of the road for the technology, analysts say.
General Motors and Honda ceased production of battery-powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford has now announced it will do the same.
Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK or Think Neighhor. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700 carts have been sold so far in 2002.
“The bottom line is we don’t believe that this is the future of environment transport for the mass market,” Tim Holmes of Ford Europe said on Friday. “We feel we have given electric our best shot.”
The Think City has a range of only about 53 miles and up to a six-hour battery recharge time. General Motors’ EVI electric vehicle also had a limited range, of about 100 miles.
The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with just $17,000 for the petrol version. Toyota and Nissan are now the only major auto manufacturers to produce electric vehicles.
“There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on,” Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.
Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines on vehicle emissions in the US.
However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.
41. What have the Ford motor company, General Motor’s and Honda done concerning electric cars? A. They have started to produce electric cars.
B. They have done extensive research on electric cars.
C. They have given up producing electric cars.
D. They have produced thousands of electric cars.
42. According to Tim Holmes of Ford Europe, battery-powered cars
A. will be the main transportation vehicles in the future.
B. will not be the main transportation vehicles in the future.
C. will be good to the environment in the future.
D. will replace petrol-powered vehicles in the future.
43. Which auto manufacturers are still producing electric vehicles?
A. Toyota and Nissan.
B. General Motor’s and Honda.
C. Ford and Toyota.
D. Honda and Toyata.
44. According to the eighth paragraph, hybrid cars
A. offer fewer mileage than petrol driven cars.
B. run faster than petrol driven cars.
C. run more miles than petrol driven cars.
D. offer more batteries than petrol driven cars.
45. Which of the following is true about the hope of car manufacturers according to the last paragraph?
A. Low-emission cars should be banned.
B. Only zero-emission cars are allowed to run on motorways.
C. The legislation will encourage car makers to produce more electric cars.
D. The legislation will allow more low-emission to be produced.

Mobile Phones
Mobile phones should carry a label if they proved1 to be a dangerous source of radiation, according to Robert Bell, a scientist. And no more mobile phone transmitter towers should be built until the long-term health effects of the electromagnetic radiation they emit are scientifically evaluated, he said. “Nobody’s going to drop dead overnight but we should be asking for more scientific information,” Robert Bell said at a conference on the health effects of low-level radiation.
46
A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill-effets on humans from electromagnetic radiation. According to Robert Bell, there are 3.3 million mobile phones in Australia alone and they are increasing by 2,000 a day. 47
As well, there are 2, 000 transmitter towers around Austrnlia, many in high density residential areas. 48 The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby.
Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds, child care centres, hospitals, sports playing fields and residential areas with a high percentage of children. 49 He adds that there is also evidence that if cancer sufferers are subjected to electromagnetic waves the growth rate of the disease accelerates.
50 According to Robert Bell, it is reasonable for the major telephone companies to fund it. Besides, he also urges the Government to set up a wide-ranging inquiry into possible health effects.
A. He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults.
B. By the year 20004 it is estimated that Australia will have 8 million mobile phones: nearly one for every two people.
C. “If mobile phones are found to be dangerous, they should carry a warning label until proper shields can be devised,” he said.
D. Then who finances the research?
E. For example, Telstra, Optus and Vodaphone build their towers where it is geographically suitable to them and disregard the need of the community.
F. The conclusion is that mobile phones brings more harm than benefit.
六、完形填空。下面的短文有15处空白，请根据短文内容为每处空白确定1个最佳选项。
Chicken Soup for the Soul：Comfort Food Fights Loneliness
Mashed potatoes, macaroni and cheese, may be bad for your arteries. 51 according to a study in Psychological Science, they’re good for your heart and 52 . The study focuses on “comfort food” and how it makes people feel.
“For me 53 , food has always played a big role in my family,” says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the study. The study came out of the research program of his co—author Shira Gabriel. It has 54 non-human things that may affect human emotions. Some people reduce loneliness by bonding with their 55 TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones. Troisi and Gabriel wondered if comfort food could have the same effect 56 making people think of their nearest and dearest.
In one experiment, in order to make 57 feel lonely, the researchers had them write for six minutes about a fight with someone close to them. Others were given an emotionally neutral writing assignment. Then, some people in each 58 wrote about the experience of eating a comfort food and others wrote about eating a new food. 59 , the researchers had participants 60 questions about their levels of loneliness.
Writing about a fight with a close person made people feel lonely. But people who were generally 61 in their relationships would feel less lonely by writing about a comfort food. “We have found that comfort foods are consistently associated with those close to us. ”says Troisi. “Thinking about or consuming these foods later then serves as a reminder of those close others. ” In 62 essays on comfort food, many people wrote about the 63 of eating food with family and friends.
In another experiment, 64 chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort food. This was a question they had been asked long before the experiment, along with many other questions, so they wouldn’t remember it.
“Throughout everyone’s daily lives they experience stress, often associated with our 65 with others,” Troisi says. “Comfort food Can be an easy remedy for loneliness. ”
