The Tasmanian devil is a rare marsupial(有袋動物)that lives only on the Australian island state of Tasmania. The doglike animal is rapidly disappearing. The Tasmanian state government estimates that the number of devils has dropped from around 150,000 in the mid-1990s to between 20,000 and 50,000 at the end of 2007.
The devil was declared an endangered species last week. It is being wiped out by a rare cancer called devil facial tumor(腫瘤)disease(DFTD). It spreads like a cold or flu from animal to animal. The disease is passed when one devil bites another. When the marsupial is infected with DFTD, large tumors develop around its mouth and neck. These growths make it impossible for the devil to eat. Many finally die from starvation within six months of being infected. As the name implies, the disease occurs only in Tasmanian devils and cannot be passed to humans.
You’ve got to remember that devils are scavengers(清掃工). They search through garbage for food. Throughout Tasmania people maintain outdoor dumps. If somebody threw out a carcass(獸類尸體), then the devils might actually consume quite large quantities of it.
The disease has not yet appeared in the devil population that lives in the northwest region of Tasmania. Conservationists have captured some of the healthy devils and sent them to a new home on the mainland of Australia. They hope these DFTD-free marsupials can be used to start a captive-breeding population. Once there are more disease-free devils, they can then repopulate the areas of Tasmania where the species are being wiped out.
Tasmanian devils play an important role in keeping the state’s ecosystem in balance. They keep the population of other predators, such as foxes and wild cats, in check. Ray Nias, head of World Wildlife Federation—Australia’s conservation program, says all Tasmanian wildlife will suffer if the devil becomes extinct. “If the devils go and the foxes and cats increase, it would be all over for a good dozen or more species of mammals, many of which are unique to Tasmania.”
46. It can be inferred that the Tasmanian devil is __________.
A. a hard-working street-cleaner                        B. a grass-eating animal
C. a meat-eating marsupial                                D. A DFTD origin
47. What’s the reason for making the Tasmanian devil endangered?
A. A rare disease called DFTD occurs in Tasmanian devils.
B. Dogs like to attack Tasmanian devils.
C. Tasmanian people try to wipe out Tasmanian devils.
D. The region of Tasmania is becoming hard for Tasmanian devils to breed.
48. To which question does the last paragraph give the answer?
A. How should people protect the devils?
B. What do the Tasmanian people do with the devils?
C. What happens if the devils disappear?
D. Which animal is closely related to the devils?
49. What measures do Tasmanian people take to stop the devils from being wiped out?
A. Trapping disease-free devils in a new place to breed more young devils.
B. Searching the cause of the disease and finding an effective treatment.
C. Developing new chemicals for the infected animals.
D. Moving all the devils to a new home on the mainland of Australia.
50. What’s true about DFTD?
A. It’s a disease that can be spread to human beings.
B. It’s a cold that occurs only in Tasmanian devils.
C. It’s a flu that Tasmanian devils get from their companions.
D. It’s a cancer that can be passed from one Tasmanian devil to another.

Drunken driving sometimes called American's socially accepted form of murder has become a national epidemic(流行。瓻very hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past ten years.A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beers, glasses of wines or shots of whisky drunk within two hours.Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts, but the drunken killing has recently caused so many well-publicized tragedies, especially concerning young children, that public opinion is no longer tolerant.
Twenty states have raised the legal drinking age to 21, reversing a trend (逆轉(zhuǎn)潮流) in the 1960s to reduce it to 18.After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers more than doubled, so the state recently upped it back to 21.
Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop "responsible attitudes" about drinking and teach them to resist peer pressure to drink.
Some states are punishing bars for serving customers too many drinks.A bar in Massachusetts was fined for serving six or more double brandies to a customer who was "obviously drunk" and later drove off the land, killing a nine-year-old boy.
As the accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years national prohibition (禁令) of alcohol that began in 1919, which President Hoover called the "noble experiment".They forget that legal prohibition didn't stop drinking, but encouraged political corruption (腐。 and organized crime.As with the booming drug trade generally, there is no easy solution.
小題1:It can be inferred from the passage that drunken driving has become a major problem in the United States because___.
A.most Americans like drinking
B.heavy dinking is hard to avoid
C.Americans are not shocked by traffic accidents
D.many Americans are killed by traffic accidents
小題2:What can be inferred from the fact of the traffic accidents in New Jersey?
A.Drivers should not be allowed to drink.
B.Young drivers were usually bad.
C.The legal drinking age should be raised.
D.Some drivers didn't reach the legal drinking age.
小題3:The underlined word "lenient" in the first paragraph means___.
A.cruelB.seriousC.determinedD.merciful§
小題4:Which of the following best shows the writer's opinion of drunken driving?
A.It may cause organized crime.
B.The new laws can stop heavy drinking.
C.There should be no bars to serve drinks.
D.It is difficult to solve the problem.

Thousands of people living in the Chinese eapital will celebrate the start of the Chinese New Year by heading for the ski resorts(滑雪場).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(熱潮).
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(郊區(qū)).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

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(內(nèi)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         .
A. the residents of 25 provinces could visit Taiwan
B. mainland tourists could stay in Taiwan for 15 days
C. the Chinese government made a string of relaxed rules

B. Chinese mainland tourists can stay in Taiwan for a maximum of 10 days
C. the global economic downturn had not influnced Taiwan’s travel industry

The faces of the elderly, happily-married people sometimes look like each other. Dr. Aiken studied a number of couples who had been married for at least twenty-five years. Each couple provided four photographs—one photo of each partner at the time of their marriage and another photo to remove any clues. The photos were then displayed in groups: a random(隨意的)grouping of the persons at the time of their marriage and another random grouping of the same persons who took photographs later. Some judges were asked to pick out the partners. They failed totally with the first group. Their judgments were no better than chance. But with the photos taken twenty-five or more years after the marriage, the judges were quite successful at deciding who was married to whom. They were particularly successful with the most happily-married couples.
Dr. Aiken believes there are several reasons why couples grow alike. One reason has something to do with imitation. One person tends to copy or do the same as someone else without knowing it. He says human beings copy the expressions of the faces of their loved ones. Another possible reason, he says, is the common experience of the couples. There is a tendency for people who have the same life experience to change their faces in similar ways. For example, if a couple suffered a lot of sad experiences, their faces are likely to change in a similar way.
56. The main purpose of the passage is to         .
tell how couples look like each other
show the life experience of husband and wife
explain why couples grow alike
describe the study on a number of married people
57. The judges failed to           .
tell couples by looking at their photos taken when they got married
tell happily-married couples from sadly-married couples
discover the difference of each partner
understand Dr. Aiken’s study
58. The underlined sentence “Their judgments were         .
A.quite successfulB.based on factsC.only by luckD.totally wrong
59. From the passage we can draw a conclusion that         .
happily-married couples are often richer than other couples
couples who look alike can live longer
the influence between couples can be quite strong
all couples have been proved to grow alike

Here is how your health risks increase at different BMIs(體重指數(shù)) if your waist circumference(腰圍) is higher than 40 inches(102 cm) in men and 35 inches (88 cm) in women:
·If your BMI is in the 18.5 to 24.9 range, or “Normal”, then a larger waist that is near or greater than 40 inches for men and 35 inches for women can indicate that you are at “increased” risk.
·If your BMI is in the 25 to 29.9 range, or “Overweight”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “increased” risk. Above these sizes,the risk is considered “high”.
·If your BMI is in the 30 to 34.9 range, or “Obese(肥胖癥)I”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “high” risk. Above these sizes, the risk is considered “very high.”
·If your BMI is in the 35 to 39.9 range, or “Obese II”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “very high” risk. Above these sizes, the risk is still considered “very high”.
·If your BMI is or in the 40 + range, or “Obese III”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “extremely high” risk. Above these sizes, the risk is still considered “extremely high”.

Peanut allergies (過敏) are among the most common and most dangerous of food allergies. A tiny exposure to peanuts can mean big trouble for a person with a peanut allergy—not just sneezing or coughing,but something as potentially deadly as narrowing of the airways.
But a recent study suggests that some children may be able to beat back their allergic reactions to peanuts by gradually introducing trace amounts of the nut into their diets. It's too early to say for certain,so if you have a peanut allergy,do not try this at home. But the first results look promising.
Two teams of scientists have been experimenting on a group“of 29 children who are allergic to peanuts”At the beginning of the study,each kid received less than 1/1,000 of a peanut per day. (Imagine splitting a peanut into 1,000 parts!) Over the course of the study, the children gradually increased the amount of the peanut in their diets
Nine of the children have been receiving the treatment for two years,and five of those nine now appear to be free of their peanut allergies,and can eat peanuts with no problem. But the other four have not benefited so much from the therapy(治療).
The two teams of scientists are now doing a follow-up study on two groups of children with the allergy. Children in one group will receive the new therapy,while the others will not. Researchers hope this study will help them learn if the therapy truly does work.
Scientists don't understand why some people get peanut allergies and others don't,but are trying to find a way to help people with the allergy. Because of the severity of some peanut allergies,scientists want to know the answer as soon as possible. “This is very encouraging, but remember,it's not something you try at home,”says one of the researchers.
68.According to the passage,the peanut allergy     .
A. can be deadly if only a small amount is used
B. causes a lot of trouble for many parents
C. allows people to eat only small amounts of peanuts
D. is considered the least common and dangerous food allergy
69.Scientists are trying to treat peanut allergies by     .
A. exposing children with the allergy to as many peanuts as possible
B. changing the eating habits of children with peanut allergies gradually
C. giving children Peanuts in slowly increasing amounts
D. exploring ways to resist the feelings caused by peanut allergies
70.The experiment shows that     
A. people with peanut allergies can't use small amounts of peanuts in their diets.
B. children are more easily cured than adults
C. all children can be cured of their peanut allergies if given more time of treatment
D. about 55-percent children with peanut allergies have been cured
71. Scientists are now doing a follow-up study in order to     .
A. explore why some people get the illness while others don’t
B. show whether peanut allergies can really be dangerous
C. check whether the therapy really works or not
D. explore whether the allergy can be cured without treatment

If you know exactly what you want, the best way to get a job is to get specialized training. A recent report shows that companies like graduates in such fields as business and health care who can go to work immediately with very little on-the-job training.
That’s especially true of booming fields that are challenging for workers. At Cornell's School of Hotel Administration, for example, bachelor's degree graduates get an average of four or five job offers with salaries ranging from the high teens to the low 20s and plenty of chances for rapid advancement. Large companies especially like a background of formal education coupled with work experience. But in the long run, too much specialization does not pay off. Business, which has been flooded with MBAs, no longer considers the degree an automatic stamp of approval. The MBA may open doors and command a higher salary initially, but the impact of a degree washes out after five years.
As further evidence of the erosion of corporate faith in specialized degrees, Michigan State’s Scheetz cites a pattern in corporate hiring practices. Although companies tend to take on specialists as new hires, they often seek out generalists for middle and upper-level management. This sounds like a formal statement that you approve of the liberal-arts(文科) graduate. Time and again labor-market analysts mention a need for talents that liberal-arts majors are assumed to have: writing and communication skills, organizational skills, open-mindedness and adaptability, and the ability to analyze and solve problems. David Birch, manager of the Boston Red Sox, says that he does not hire anybody with an MBA or an engineering degree. “I hire only liberal-arts people because they have a less-than-canned way of doing things,” says Birch.
For a liberal – arts degree, students focus on some basic courses that include literature history, mathematics, economics, science, human behavior and a computer course or two. With these useful and important courses, you can feel free to specialize, “A liberal-arts degree coupled with an MBA or some other technical training is a very good combination in the marketplace,” says Scheetz.
67.The job market is in great need of people with          .
A.special training in special fields
B.a(chǎn) bachelor’s degree in education
C.formal schooling and work experience
D.a(chǎn)n MBA degree from top universities
68.The underlined sentence in Paragrph 2 means         .
A.a(chǎn)n MBA degree does not help in future promotion
B.MBA programs will not be as popular as they are now
C.people will not forget the degree the MBA graduates have got
D.most MBA programs fail to provide students with a foundation
69.David Birch says that he only hires liberal – arts people because          .
A.they will follow others’ ways of solving problems
B.they can do better in bundling changing situations
C.they are well trained in a variety of specialized fields
D.they have attended special programs in management
70.The author supports the idea that          .
A.on – the – job training is less costly in the long run
B.formal schooling is less important than job training
C.specialists are more expensive to hire than generalists
D.generalists will do better than specialists in management
