The Green Microgym in Portland，Oregon has all the usual stuff you'd expect-sweaty people，loud music，smooth exercise equipment-but it has some extras as well. Everywhere you look，there are power wires. And these aren't the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too．The gym uses special exercise equipment that captures（捕获）the energy you create while riding, converts（转换）it into electricity and channels it into the power outlets（插座）．
The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy）energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months，which is a good sign that fitness centers are ready to spend money on green technologies，” says Mike Curnyn，co-founder of the Green Revolution，a Connecticut-based firm that wires bikes into a central battery that can store energy.
The Green Microgym，first opened in 2008，has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original．Although membership costs about the same as ordinary gyms，customers can earn gift certificates from local businesses for watts produced while exercising．An average workout creates 37. 5 watt hours，which is enough to power a phone for a week．
Boesel uses spin bikes made by Resource Fitness，a Seattle company he co-owns，that captures energy produced from the flywheel. Wires send the converted AC current（交流电流）into any standard wall outlet-for this reason，the product line's name is Plug Out-and the energy created is used before the building draws power from the grid（电网）．Unlike the Green Revolution equipment，Plug Out machines cannot store extra energy. A third company，the Florida-based ReRev，is adding converters to a specific brand of spin bikes. But since the converters add＄1，000 to the price of the equipment，the ReRev and Green Revolution machines are at a disadvantage．
Resource Fitness，by contrast，sells its equipment for the same＄1，200 price as non- electricity-producing machines，removing the question of how long it will be until the energy savings pay for the cost of the unit．The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters．It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch．Members of the Green Microgym earn gift certificates for_______．
| A．using the man-powered exercise equipment |
| B．saving electricity for local businesses |
| C．producing green electricity to power their phones |
| D．paying higher membership fees |
The spin bikes made by Resource Fitness are different from those by Green Revolution in that_______.
| A．they are easier to ride |
| B．they are more expensive |
| C．they don't have wires connected |
| D．they can not store extra electricity |
What might prevent the green exercise equipment from getting more popular？
| A．People's unwillingness to go green． |
| B．The high cost of making it. |
| C．Safety problems concerning electricity. |
| D．Lack of certificates． |
The underlined words“make the switch”in the last paragraph most probably mean_____.
| A．change to a different gym |
| B．use green exercise equipment |
| C．switch on the spin bikes |
| D．add a battery to the machine |
Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.
During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.
Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.
Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.
Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.
72. The most suitable title for this passage would be ______.
A. Places for Disposing Waste B. Waste Pollution Dangers
C. Ways of Getting Rid of Waste D. Waste Disposal Problem
73. During the 18th century, people disposed their waste in many ways EXCEPT for ______.
A. burying it B. recycling it
C. burning it D. throwing it into rivers
74. What can be inferred from the fourth paragraph?
A. Farm areas accept waste from the city in modern society.
B. There is cheap land to bury waste in modem society.
C. It is difficult to find space to bury waste in modem society.
D. Ways to deal with waste in modem society stay the same.
75. The main purpose of writing this article is to ________.
A. draw people's attention to waste management
B. warn people of the pollution dangers we are facing
C. call on people to take part in recycling programs
D. tell people a better way to get rid of the waste
Sheep, like turkeys and ostriches, are not considered the cleverest animals. British scientists said last Wednesday human may have underestimated(低估) the woolly creatures. They could be much smarter than we think.
Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good 
at recognizing faces--which they think is a sure sign of intelligence.
Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and used electrodes(电极) to measure their brain activity, which showed they could remember 50 faces for up to two years.
"If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview.
So hours of seemingly mindless eating grass may not be so mindless after all.
Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much individuality and are frightened of just about everything.
"All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained.
In re
search reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.
"The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick. "It is a very strange system. They are showing similar abilities in many ways to humans. "
68. From the first paragraph we can find that ______.
A. people used to think sheep are smarter than the other animals
B. people used to raise sheep in a wrong way

69. From what Kendrick said in the interview we learn that ________.
A. scientists have learned a lot about sheep's intelligence
B. scientists have learned little about sheep's intelligence
C. scientists can't do anything more about sheep's memory
D. scientists don't have to research animals' memory
70. As is shown in the passage _________.
A. sheep are among the weak animals
B. it is not right for people to raise sheep in groups
C. when sheep eat grass in the fields their minds may be active
D. if people feel frightened, they may become more brave
71. When scientists found that sheep show similar abilities in many ways to humans they may think it _____.
A. worrying B. moving C. frightening D. interesting
When I opened my e-mail the other day, a pretty woman named Rachel appeared on my computer screen. She greeted me by name and started talking with great enthusiasm. Every now and then she stopped to smile at me or blow a kiss. She was reading to me an e-mail from my brother, and a lot of it was about his getting the phone company to give him a high-speed Internet connection. It was pretty cool.
Rachel was there thanks to a new technology called Facemail. Facemail lets you send e-mail that gets ready to the receiver by an attractive male or female form or by a clown(小丑). The software, which is free, can be downloaded at www. Facemail.com.
Facemail faces are lifelike, and they simulate(模拟) emotions based on emotions that you put in your text. For example, type in-X, and Rachel blows a kiss.
LifeFX, the company that develops the Facemail, is sure there are broad business uses. The reason e-business is not popular, the company says, is that buying over the Internet lacks the human touch. But what if you went to the Nike website and Michael Jordan greeted you by name, waited on you and personally closed the sale? And it is talking with Whirl(惠而浦公司) about using the technology in a computer screen on a fridge. Then if Morn can't be home when the kids get back from school, she can leave a note with voice and image telling them what there is to eat.
Facemail could get hot fast. Personally, I'm a fan. But Facemail should be used with care. The clown looks lively and funny at first. But if you select the clown, put a few rude words in an e-mail and add some angry emotions, you've got a Psycho-mail(疯人型电子邮件).
64. The pretty woman that appears on the writer's computer screen was ______.
A. a woman working on the Internet B. his brother's girlfriend
C not a real person D. the picture of his pen-friend
65. The main advantage of Facemail is that ______.
A. you can hire a beautiful woman to read the e-mail to you
B. you can see the person who sends you the e-mail
C. yon can send an e-mail free of charge
D. e-mail can be attractive in a more lovely way
66. The writer mentioned Nike website and Michael Jordan to show that _______.
A. Famous people like Michael Jordan also like to use Facemail
B. Facemail can make shopping on the Internet more interesting
C. Nike website will increase its sales by Jordan
D. Michael Jordan will serve you himself on Nike website
67. What is the writer's attitude towards Facemail?
A. He thinks it needs further improvement.
B. He thinks it cool and funny.
C. He thinks it a danger to the Internet.
D. He thinks people should be careful with Facemail.
Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined(限于) to the aged. There may be a million or more people under the age of 65 suffering from the disease.
At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic(器官的) disease that destroys brain cells.
Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking. Then the patient's memory begins to fail. He may forget dates, telephone numbers, names and plans.
As the disease progresses, the patient may not recognize family and friends. These symptoms(症状) often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.
In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.
Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus(病毒). It may be caused by a poisonous substance(物质) in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.
60. The main idea of the passage is that Alzheimer's disease _______.
A. is a terrible part of the aging process B. is an organic disease that affects young and old
C. can be cured by physical treatment D. causes forgetfulness
61. All of the following are symptoms of Alzheimer's disease EXCEPT _______.
A. forgetfulness B. difficulty in speaking C. loss of sight D. loss of the ability to walk
62. According to the passage, which of the following may be a cause of Alzheimer's disease?
A. Poisons produced by the brain. B. Getting old. C. A virus. D. Lack of exercise.
63. The progress of Alzheimer's disease can be slowed by ______.
A. operation B. a change in environment C. medicines D. physical treatment and exercise
第三部分：阅读理解（共20小题；每小题2分，满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑。
A device that stops drives from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20%—40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drives or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel(
方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver's response.
Tiredness is directly re
lated to a driver's response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver's response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department's laboratories for testing. If these tests, scheduled for six months' time, are successful, the makers will bring the product to market within about a year.
56. According to the text, Driver Alert ______.
A. aims to reduce tiredness-related accidents B. aims to prevent drivers from sleeping
C. has gone through testing at laboratories D. has been on sale for 12 months
57. How should a driver respond to the sounds from Driver Alert?
A. By sounding a warning. B. By checking the driving time.
C. By touching the wrist hand. D. By pressing the steering wheel.
58. We can learn from the text that the driver needs to stop for a break when his response time is _____.
A. about 400 milliseconds B. over 500 milliseconds
C. below 500 milliseconds D. about 4 minutes
59. When the driver gets sleepy while driving, Driver Alert ______.
A. moves more regularly B. opens the window for the driver
C. stops working properly D. sounds more frequently and loudly
