The sleep debt is the difference between the amount of sleep you should get and the amount you actually get. It grows every time we skim some extra minutes off our nightly sleep. “People accumulate sleep debts gradually,” says Dr. William Dement, founder of the Stanford University Sleep Clinic. Studies show that such short-term lack of sleep leads to a foggy brain, impaired vision, worsened driving and troubled remembering. Long- term effects include obesity, insulin(胰岛素) resistance, and heart disease.
A 2007 survey by the National Sleep Foundation reports that Americans sleep for 6.9 hours per night, 6.8 hours on average during the week and 7.4 hours on the weekends. Generally, experts recommend eight hours of sleep per night, although some people may require only six hours of sleep while others need ten. That means on average, Americans lose one hour of sleep each night more than two full weeks of sleep every year.
The good news is that the sleep debt can be repaid with some work, though it won’t happen when you sleep longer for once. Adding an extra hour or two hours of sleep a night is the way to catch up. For the long-term sleep shortage, it takes a few months to get back to natural sleeping pattern, says Lawrence J. Epstein, medical director of the Harvard Sleep Health Center.
Go to bed when you are tired, allowing your body to wake you in the morning, with no alarm clock. You may find yourself uncomfortable at the beginning of the recovery cycle. Expect to bank to ten hours shut-eye per night. As the days pass, however, the amount of sleeping time will gradually decrease. For recovery sleep, both the hours of the sleep and the intensity(强度) of the sleep are important. The most refreshing sleep occurs during deep sleep, which is generally considered a restorative (促使健康的) period for the brain. And when you sleep for more hours, you allow your brain to spend more time relaxing.
As you reduce the sleep debt, your body will come to rest at a sleeping pattern that is specifically right for you. Sleep researcher believe that genes determine our individual sleeping patterns. So you can’t train yourself to be a “short sleeper”. A 2005 study in the journal Sleep found that the more tired we get, the less tired we feel.
46. Which of the following is NOT the side effect of sleep debt?
A. Putting on weight. B. Having a bad memory.
C. Having trouble eating food. D. A temporary loss of eyesight.
47. We learn from the 2007 survey that _______.
A. Americans generally don’t have enough sleep
B. Americans sleep too much over the weekends
C. everyone is supposed to sleep for eight hours
D. most people lack two weeks of sleep every year
48. What should we do to make up for the sleep shortage?
A. We should go to sleep when we are free.
B. We should sleep for at least ten hours every day.
C. We should sleep for one or two more hours at night.
D. We should sleep day and night during the holidays.
49. Why is the intensity of the sleep important to us?
A. Our brain is resting when we are sleeping deeply.
B. Deep sleep helps our brain to fully recover.
C. We feel more relaxed when sleeping soundly.
D. Short sleep makes our body more refreshing.
50. The author seems to believe that _________.
A. the more tired we are getting, the more sleep we need
B. the sleeping patterns have nothing to do with our genes
C. it is possible for us to reduce our sleep time by training
D. it is wise for us to adapt to our natural sleeping patterns.

Scientists have developed a water treatment system that they say is a powerful but simple way to save lives. Four grams of chemicals can treat ten liters of dirty water for a low cost, about ten cents.
Experts say infections from dirty water kill several thousand children in developing countries every day. The Procter and Gamble company has been developing the "PUR Purifier of Water" system since 1995. The company has been working with the United States Centers for Disease control and Prevention(C.D.C.).
C.D.C. researchers tested it in Guatemala, Pakistan and Kenya. Procter and Gamble researcher Greg Allgood says cases of diarrhea(腹泻) in those studies fell by about 50 percent. Researchers from Johns Hopkins University in Maryland tested the system at a refugee camp in Liberia. Mr. Allgood says that study found a reduction of more than 90 percent. Use of the system is being expanded worldwide.
The treatment contains bleach(漂白剂) to kill disease-causing organisms. It also contains something that dirt and other particles stick to. Mr. Allgood says the chemicals can remove lead and other dangerous metals and even agricultural poisons like D.D.T.
Mr. Allgood heads the Children's Safe Drinking Water program at Procter and Gamble. He says about forty million packets of the treatment have been given to countries for free. They have been used in emergencies and in areas with limited supplies of clean water.
Clean water is a limited resource in many parts of the world. Delegates from about 130 nations attended the Fourth World Water Forum last month in Mexico City. Scientists, policy experts and others discussed ways to provide clean water to the world’s poor. Organizers say more than twenty percent of the world population lacks clean drinking water. The final declaration did not go so far as to declare water a human right. But it did say that governments, not private companies, must take the lead in improving the public’s ability to have clean water.

A. Water pollution around the world.
B. The causes of diarrhea in African countries.
C. A newly developed water treatment system.
D. The Fourth World Water Forum in Mexico City.
47. Which of the following developed the water treatment system?

B. The Procter and Gamble Company and C.D.C.
C. The Children’s Safe Drinking Water Program.
D. Johns Hopkins University.
48. Which of the following about the new water treatment system is NOT true?
A. It is effective but very expensive.
B. It was tested in Guatemala, Pakistan and Kenya.
C. It is being expanded worldwide.
D. It can remove dangerous metals in the water.
49. Which of the following shows that the shortage of clean water is a serious problem?
A. Forty million packets of the treatment have been given to countries for free.
B. Delegates from about 130 nations attended the Fourth World Water Forum.
C. Four grams of chemicals can treat liters of dirty water for a low cost.
D. Infections from dirty water kill several thousand children every day.

Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.
They found that when people listened to their favorite music, their blood vessels (血管) dilated in much the same way as when they are laughing, or taking blood medications.
"We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology (心脏病学) at the University of Maryland Medical Center in Baltimore.
"Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins.
When blood vessels open up more, blood flows more smoothly and is less likely to form the clots (凝块) that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans.
Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function.
Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked — in most cases in this group heavy metal — blood vessels narrowed by six percent, Miller said.
Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel really good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said.
Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual.

A centuries-old tradition of wearing a white horse-hair wig in court ended for many judges when a simpler new dress code came into force．
While judges in criminal cases will still wear them, those in civil and family hearings will appear bare-headed in court, wearing a new-style plain black robe, the British government said．
After a long debate, the Lord Chief Justice, Lord Philips, head of the judiciary(司法部) in England and Wales, finally ordered the changes in an attempt to modernize the courts．
Wigs have been an emblem(象征) of the British legal system since the 17th century when the fashion for wearing them in wider society went through to the courts．For hundreds of years before the reign(统治)of Charles II, judges and lawyers were expected to come to court with short hair and a beard．
The decision to abandon wigs has disappointed traditionalists who argue that they give judges an air of authority and impartiality．Wigs could also protect them from angry members of the public．John Mortimer, the barrister and author of the “Rumpole of the Bailey” books, opposed the changes．“The idea’s ridiculous! A barrister without his wig would be like a doctor without a stethoscope（听诊器）,” he wrote in a newspaper article when the changes were first proposed．
However, modernists argue that wigs are a hangover from the past that could intimidate people in court．In a newspaper interview, Lord Phillips described wigs as an anachronism（不合时宜之物）that gave the public a false impression of judges．
A Ministry of Justice survey last year found 70 percent of court workers wanted to keep wigs, compared to 42 percent of the public．
1．The reasons why wigs should be kept are the following EXCEPT________．
A．to build up the fair image of the judges．
B．to keep the judges from the harm from the audience．
C．to make the audience fear the judges．
D．to symbolize justice．
2．According to the British government, wigs will still be worn in ________．
A．murder cases B．divorce cases C．property cases D．real estate cases
3．The underlined word ‘intimidate’ in Paragraph 4 means ________．
A．frightened B．dissatisfied C．amused D．annoyed
4．Based on the article, which of the following inferences is TRUE?
A．Wearing wigs were very popular in the 17th century in Britain．
B．A stethoscope to a doctor is what a wig to a traditionalist．
C．The courts started the fashion of wearing wigs．
D．Many people favor the wigs for the judges．
5．The article is mainly about _________．
A．the difficulty in abandoning wigs in court．
B．the history of wearing wigs and the end of it．
C．abandoning wigs for many judges and the debate caused by it．
D．the opinion of the public and court workers on abandoning wigs．

Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain Cases, harmful.
In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pennsylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins (毒素) better, improves skin, and helps reduce weight.
Dr Goldfarb and Dr Negoianu say that they found little proof to support the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they found little proof of harm in drinking 8 glasses of water every day.
It is widely believed that in some cases — such as athletes, people who live in hot, dry environments, and those with certain medical conditions — drinking a lot of water indeed helps, but no studies have been done to prove the benefits of this practice in average, healthy people, the website medheadlines. com reports.
The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, “but the difference in the number of headaches was so small between the two groups as to be considered unimportant.”
The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each day.
The website medheadlines. com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur.
1. What’s the key message delivered in the passage?
A. Drinking too much water might bring harm.
B. Whether to drink enough water makes no difference.
C. Drinking too much water may cause headaches.
D. Average, healthy people should drink more water.

A. proves good for the body             B. has scientific proof of harm
C. is sure to reduce headaches            D. is generally considered necessary
3. Who may agree that drinking lots of water helps to lose weight?
A. Two experts.                     B. General public.
C. An Indian doctor.                  D. A website.
4. According to the passage, we know that ________.
A. the website medheadlines. com is developed by an Indian doctor
B. the study was carried out by two experts with an Indian doctor
C. the two experts performed the study at the University of Pennsylvania
D. drinking 8 glasses of water every day can cure certain diseases

At one time or another most farmers have problems with mice. This is especially true for grain farmers. Mice eat a lot of grain. They also carry diseases(疾病), which people can get from eating or touching grain the mice have made dirty. Farmers can use special grain storage building or they can kill the mice. However, both methods can be costly. Farmers must buy materials to build the special grain storage buildings or chemical poisons to kill the mice.
Here is a way to kill mice without spending a lot of money. It is a simple but effective king of mouse trap. The method is first used by some farmers in the west African country of Mali. An agricultural expert in Mali reported about the Mali mouse trap in a magazine. The expert reported that his gardener caught 150 mice in just one night. The gardener used four traps. The trap is easy to make. First, remove the top from a 20 liter metal or plastic container(容器). Put it n a hole in the ground. The top edge of the container should be the level with the surface of the ground. Fill the container with water to within eight centimeters of the top. Add tiny pieces of grain wastes. They should float on the water. Also put some wastes on the ground near the trap. During the night, mice will come out to eat the grain wastes. They will fall into the container and drown. Replace the food in the trap every night.
56. According to the passage,       used the mouse trap first.
A. an agricultural expert in the west Africa      B. farmers in the United States
C. an American gardener                    D. farmers in Mali
57. What does the passage mainly tell us?
A. A simple and effective method used by farmers to kill mice.
B. Methods used by farmers to kill mice.
C. Farmers have problems with mice.
D. How to kill mice.
58.      is not needed in making the mouse trap.
A. Water                            B. A container
C. chemical poison                    D. Food
59. Which of the following can’t protect grain from being eaten by mice?

Thousands of people living in the Chinese eapital will celebrate the start of the Chinese New Year by heading for the ski resorts(滑雪场).Never mind that Beijing’s dry weather seldom produces
Now. It is cold enough in winter for snow-making machines to make a covering for the hills north to
The capital. And the rapid growth of a pleasure-seeking middle class has formed the basis for this
New craze(热潮).
Since Beijing’s first ski resort was opened ten years ago, the sport has enjoyed an astonishing increase.There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr.Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that could soon lead Chinese to head for the ski resorts of Europe. In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can’t really match the equipment and services of some ski resorts
In Europe.
Beijing’s sking craze is partly a result of the recent increase in private(私有的)cars. This has led to the growth of a leisure industry in the capital’s suburbs(郊区).which until the late-1990s were unreachable to ordinary people. According to Mr. Wei,About 40％ of the visitors to his resort some in their own cars. The rest are bused in by schools, businesses or government offices.
The problem is making money.Starting ski resorturequires quite a lot of money:hiring land from the local government,preparing the hills,buying snow machines,making sure there are enough
water and electricity to run them,and buying ski equipment for hiring out to customers.The ski resort where Mr.Wei works cost nearly $4m to set up.And,as so often in China when someone comes up with a good idea,many others rush in and price wars break out.Beijing now offers some of
the cheapest ski training classes in the world,though with most people rather new to the sport, expecting a few more doing the same job.
50.What does this text mainly talk about?
A．Convenience for skiers brought about by private cars
B．Skiing as a new way of enjoying one’s spare time
C．Things to be considered when starting a ski resort
D．A sudden increase of ski training classes in Beijing
51.Why are some Chinese likely to go skiing in Burope?
A．To visit more ski areas
B．To ski on natrual snow
C．For a large collection of ski suits
D．For better services and equipment
52.The underlined words”leisure industry”in Paragraph 3 refer to
A．transport to ski resorts
B．production of familycars
C．business of providing spare time enjoyments
D．part-time work for people living in the suburbs
53.What is the main problem in running a ski resort?
A．Difficulty in hiring land
B．Lack of business experience
C．……ski resorts.
D．Shortage of water and electricity

More than 600, 000 tourists from the Chinese mainland visited Taiwan last year, fulfilling expectations despite the impact of H1N1 flu and the global economic downturn.
A total of 606, 100 mainland tourists visited Taiwan in the past year, with each spending nearly $1, 800 on the island, including accommodation and shopping, Shao Qiwei, chairman of the Beijing-based Association for Tourism Exchange Across the Taiwan Straits, said on Friday.
“We see good cooperation between tourism industries across the Straits taking shape,” Shao said. Since July 2008, when Taiwan first opened to mainland tourists, about 660, 000 mainland tourists have visited the island and spent $1.13 billion there, benefiting local transportation as well as the retail, entertainment and health industries.
In four months starting August last year, mainland tourists spent $65.72 million through UnionPay payment cards, figures from mainland bankcard association China UnionPay showed.
“Years of isolation between the two sides have made Taiwan an attractive place for mainland tourists,” said Zheng Lijuan, deputy (副的) general manager of CITS International MICE Co. Ltd.
But under the impact of H1N1 flu since May, the number of mainland tourists to Taiwan had also dropped sharply, leading to industry insiders（内部的人）casting doubt as to whether the goal of attracting 600, 000 mainland tourists to Taiwan in 2009 could be achieved.
Despite the unfavorable conditions, a string of relaxed rules last year have spurred (刺激) the interest of mainland tourists in visiting Taiwan.
In the past year, Taiwan has opened to mainland residents in 25 provinces, up from the initial 13 provinces. Relaxed rules have also allowed five tourists to form a group to visit Taiwan, instead of the initial requirement of at least 10 tourists. Mainland tourists can also stay in Taiwan for a maximum of 15 days, instead of the initial 10 days.
Combined with mainland business groups, more than 900, 000 mainland travelers visited Taiwan in 2009, Christine Lai, director of the Taiwan Strait Tourism Association, told China Daily.
Without releasing the goal for this year, Lai expressed hopes that mainland tourists would head to Taiwan on second or even third visits.
66. Why do mainlanders like to visit Taiwan?
A. Taiwan is a very beautiful island.
B. There are many shops, malls and bookstores in Taiwan.
C. The accommodation and transportation are very good in Taiwan.
D. Years of isolation between Taiwan and mainland makes it an attractive place.
67. What was the original goal of mainland tourists to Taiwan in 2009?
A. 660, 000                     B. 606, 100                      C. 600, 000                         D. 900, 000
68. The number of mainland tourists to Taiwan in 2009 was fulfilled because         .

B. mainland tourists could stay in Taiwan for 15 days
C. the Chinese government made a string of relaxed rules
D. there were no impacts of H1N1 flu in Taiwan and mainland
69. We can infer from the text that         .
