　　Part III Reading Comprehension (45 minutes, 25 points, 1 for each)

　　Directions: There are 5 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them, there are 4 choices marked A, B, C and D. Choose the best one and mark the corresponding letter with a single bar across the square brackets on your machine-scoring ANSWER SHEET.

　　Passage One

　　At all ages and at all stages of life, fear presents a problem to almost everyone. “We are largely the playthings of our fears,” wrote the British author Horace Walpole many years ago. “To one, fear of the dark; to another, of physical pain; to a third, of public ridicule; to a fourth, of poverty; to a fifth, of loneliness — for all of us our particular creature waits in a hidden place.”

　　Fear is often a useful emotion. When you become frightened, many physical changes occur within your body. Your heartbeat and responses quicken; your pupils expand to admit more light; large quantities of energy-producing adrenaline(肾上激素)are poured into your bloodstream. Confronted with a fire or accident, fear can fuel life-saving flight(逃离). Similarly, when a danger is psychological rather than physical, fear can force you to take self-protective measures. It is only when fear is disproportional to the danger at hand that it becomes a problem.

　　Some people are simply more vulnerable to fear than others. A visit to the newborn nursery of any large hospital will demonstrate that, from the moment of their births, a few fortunate infants respond calmly to sudden fear-producing situations such as a loudly slammed door. Yet a neighbor in the next bed may cry out with profound fright. From birth, he or she is more prone to learn fearful responses because he or she has inherited a tendency to be more sensitive.

　　Further, psychologists know that our early experiences and relationships strongly shape and determine our later fears. A young man named Bill, for example, grew up with a father who regarded each adversity as a temporary obstacle to be overcome with imagination and courage. Using his father as a model, Bill came to welcome adventure and to trust his own ability to solve problem.

　　Phil’s dad, however, spent most of his time trying to protect himself and his family. Afraid to risk the insecurity of a job change, he remained unhappy in one position. He avoided long vacations because “the car might break down.” Growing up in such a home, Phil naturally learned to become fearful and tense.

　　31.In the last sentence of Paragraph 1, “our particular creature” refers to .

　　A.fear of somethingB.a fierce beast

　　C.physical painD.public ridicule

　　32.Fear can be a useful emotion to us because it can .

　　A.stimulate many physical changes within our body

　　33.Fear becomes a problem only when .

　　A.the danger is thought greater than it really is

　　B.the danger is more psychological than physical

　　C.one cannot stand the danger

　　D.one is not well prepared for it

　　34.Different responses of newborn infants to a loudly slammed door imply that .

　　A.some people are inherently more easily affected by danger

　　B.people’s response to stimuli is not an inherited feature

　　C.some people seem to be very sensitive to noise

　　Passage Two

　　Sea horses are unusual parents. The female sea horses lay the eggs, but unlike other creatures, it’s the males that give birth to the young.

　　Male sea horses have a fold of skin on their bellies that forms pocket, called a brood pouch. During the breeding season, the sea horse’s pouch swells to receive eggs. A female sea horse lays up to 200 eggs at a time in the pouch. Then she swims off, leaving her male partner to care for the developing eggs and give birth to young sea horses. The female will return everyday to check on her mate and the eggs, but she doesn’t stay long, nor does she take part in the birth.

　　It takes from two to six weeks for the eggs in the male’s pouch to develop. During this time the male avoids open water and hides in sea grass. His big pouch makes it difficult for him to swim, so the male often uses his tail to grasp a piece of sea grass. Firmly gripping the grass, he will stay perfectly still for hours or even days. The male sea horse will change his color to blend with his surroundings and avoid being seen by predators who will try to eat him or poke holes in his pouch to get the eggs.

　　The eggs hatch inside the male’s pouch. When the babies begin moving around, the male sea horse knows it’s time for them to be born. He grabs a sea grass stem with his tail and begins rocking, bending, and stretching his body so that the rest of the babies can be born. Sometimes he has to press his pouch against a rock or some stiff seaweed to force the young out.

　　Sea horse babies are born in groups of five or more. Sometimes it takes two days for the father sea horse to give birth to all his young. He is very tired when it’s over.

　　Soon after giving birth to one brood, the male will approach his mate and show her his empty pouch. This tells her he is ready to receive eggs again.

　　36.What part does the female sea horse play in having babies?

　　A.Receiving eggs.B.Laying eggs.C.Hatching eggs.D.Protecting eggs.

　　37.What can be learned from the passage about giving birth to baby sea horses?

　　A.It is dangerous for the female.B.It happens once a year.

　　C.It is hard work for the male.D.It occurs in the deep sea.

　　38.To protect himself and his eggs, the male sea horse does all the following EXCEPT .

　　A.changing his colorB.gripping a piece of grass

　　C.staying motionlessD.enlarging his pouch

　　39.The author suggests that when sea horse babies are ready to be born .

　　A.the male sea horse seems very happyB.it is difficult for them to come out

　　Passage Three

　　When 23-year-old Eric Atienza graduated from college last year, he didn’t have a job. Not wanting to give up his apartment and move back with his parents, he did what many young Americans are doing: he signed up with a temp agency, which places workers on short-term jobs. Temporary workers such as Atienza comprise 20 per cent of the U.S. workforce. In 1985, 417,000 workers were classified as temporary help. In 2005, there are more than 2.5 million, according to Labour Department data.

　　Using temporary workers allows companies to increase or decrease the number of staff as their workloads change. It also allows companies to avoid the costs involved in hiring and firing long-term employees.

　　Many temp agency owners and career specialists say temping is a good way for recent graduates to get experience. “Short-term jobs let graduates try out different companies to find the best fit,” said Pegi Wheatley, owner of McCall Staffing, a San Francisco temp agency.

　　But things don’t always work out that way. “When I started temping, I had this notion that a temporary job could turn full-time. I worked for a friend of mine, but that didn’t happen for me,” said Atienza, who quickly became bored with his office work. Atienza stayed with the temp agency because he could earn U.S.$10 an hour doing office work. Other short-term jobs, such as working as a store clerk in a café, pay about U.S.$7.

　　But there were trade-offs for the higher pay. Because in the U.S., health insurance is provided through employer, most temps are not eligible for workplace health benefits. Atienza ran the risk that an accident or illness would land him in the hospital with no way to pay the bill. Other drawbacks, though less serious, still mean that temping for most graduates is exactly what its name implies — a temporary choice. Instability, gaps between contracts, lack of vacation time and isolation from other employees are often-cited negatives.

　　“Temping gave me the time to figure out what I wanted to do, because I could pay off my bills. But none of that came from the jobs themselves,” said Atienza, who quit temping last month in favor of a full-time job.

　　41.Atienza took a short-term job mainly because .

　　A.he didn’t want to give up his apartment

　　B.he liked to try out different companies

　　C.he wanted to get more experience

　　D.he couldn’t find a long-term job

　　42.According to the passage, in the year of 2005, the United States had workforce of more than .

　　A.25 millionB.12.5 millionC.4.17 millionD.2.5 million

　　43.Which is NOT mentioned as an advantage of temping?

　　A.It gives recent graduates experience.

　　B.It enables employers to adjust their workforce.

　　C.A temporary job will turn full-time.

　　D.Employers can reduce their costs.

　　44.Atienza stayed with the temp agency for some time because .

　　A.he liked his office workB.he was satisfied with the pay

　　C.his employer provided health insuranceD.he hated gaps between contracts

　　45.What does the word “trade-offs” in Paragraph 5 mean?

　　A.Benefits.B.Compromises.C.Risks.D.Disadvantages.

　　Passage Four

　　Scientists are hoping to eliminate malaria(疟疾)by developing a genetically modified mosquito that cannot transmit the disease. Malaria has long troubled the populations of South America, Africa, and Asia, where mosquito bites infect up to 500 million people a year with this serious and sometimes fatal parasitic blood disease. For generations, scientists have been trying to eliminate malaria by developing new drugs and using pesticides(杀虫剂)to wipe out local mosquito populations. But these measure aren’t working — and some scientists, like Greg Lanzaro, say that because of drug resistance and population changes, malaria is actually more prevalent now than it was 20 years ago. Lanzaro says he has a better way to stop the spread of malaria: genetically modifying mosquitoes so they are unable to carry the disease.

　　Lanzaro and his colleagues are planning a multi-year project to produce malaria-resistant mosquitoes — and he thinks they can do it within five years. “We can get foreign genes into mosquitoes and they go where they’re supposed to go,” Lanzaro says, pointing out that scientists have already succeeded in genetically engineering mosquitoes that cannot transmit malaria to birds and mice. And, he says, scientists are quickly making progress on genes that block transmission of the disease to humans as well.

　　The most difficult part scientifically, Lanzaro says, is figuring out how to get the lab-engineered mosquitoes to spread their genes into natural populations. After all, he points out, it’s useless to engineer mosquitoes in the lab that can’t transmit malaria when there are millions out in the wild that can. To solve this problem, Lanzaro wants to load up a mobile piece of DNA with the malaria-resistant gene, and then insert it into a group of mosquito embryos. The malaria-resistant gene would be integrated directly into the mosquitoes’ DNA, making it impossible for those mosquitoes to transmit the parasite that causes malaria.In this way a small group of lab-raised mosquitoes could be released into the wild, and by interbreeding with wild mosquitoes, eventually transmit the beneficial gene to the entire population.

　　46.One reason for malaria to be widespread now is that .

　　A.more people have moved to malaria-infected areas

　　B.mosquitoes have become resistant to pesticides

　　C.genetically modified mosquitoes still transmit the disease

　　D.mosquitoes bite as many as 500 million people a year

　　47.Lanzaro is hopeful that in a few years man can .

　　A.start to eliminate malaria

　　B.cure parasitic blood diseases

　　C.prevent mice from transmitting parasites

　　D.acquire immunity against malaria

　　48.Lanzaro is confident that scientists can block transmission of malaria to humans because

　　A.natural mosquito populations do not change

　　B.scientists have succeeded with birds and mice

　　C.foreign genes always go where they are required

　　D.lab-raised mosquitoes will not be resistant to drugs

　　49.What is the most difficult part of Lanzaro’s project?

　　A.Spreading malaria-resistant genes into natural mosquito populations.

　　B.Raising malaria-resistant mosquitoes.

　　C.Making genes that block the transmission of malaria.

　　D.Identifying malaria-resistant genes.

　　50.According to the passage, a fundamental way to wipe out malaria is to .

　　A.develop new malaria-resistant drugs

　　B.produce effective pesticides to kill mosquitoes

　　C.change the genetic makeup of mosquitoes

　　D.remove people from malaria-infected areas

　　Passage Five

　　According to Scott Adams, creator of the comic strip(系列漫画)Dilbert, the annual performance review is “one of the most frightening and weakening experiences in every employee’s life”. Adams’ stories and comic figures poke fun at the workplace, but his characterization of people’s feelings about the annual performance review has its serious side. Although a recent study of 437 companies indicates that effective annual performance reviews can help raise profits, most employees of those companies hate them.

　　In theory, annual performance reviews are constructive and positive interactions between managers and employees working together to attain maximum performance and strengthen the organization. In reality, they often create division, undermine morale, and spark anger and jealousy. Thus, although the object of the annual performance review is to improve performance, it often has the opposite result. A programmer at an IT firm was stunned to learn at her annual performance review that she was denied a promotion because she wasn’t a “team player.” What were the data used to make this judgment? She didn’t smile in the company photo.

　　Although this story might sound as if it came straight out of Dilbert, it is a true account of one woman’s experience. By following a few ideas and guidelines from industry analysis, this kind of ordeal can be avoided:

　　To end the year with a positive and useful performance review, managers and employees must start the year by working together to establish clear goals and expectations.

　　It may be helpful to allow employees to propose a list of people associated with the company who will be in a good position to assess their performance at the end of the year; these people may be co-workers, suppliers, or even customer.

　　Goals should be measurable but flexible, and everyone should sign off on the plan.

　　By checking employees’ progress at about nine months, managers can give them a chance to correct mistakes and provide guidance to those who need it before the year is out.

　　When conducting the reviews, managers should highlight strengths and weaknesses during the past year and discuss future responsibilities, avoiding punishment of blame.

　　In short, when employees leave their performance reviews, they should be focusing on what they can do better in the year ahead, not worrying about what went into their files about the past.

　　51.In his comic strip Dilbert, Scott Adams .

　　A.makes fun of working peopleB.tells a story about a woman employee

　　C.promotes team spirit among co-workersD.mocks annual performance reviews

　　52.All the following are mentioned as the drawbacks of annual performance reviews EXCEPT .

　　A.reducing efficiencyB.creating tension

　　C.undermining moraleD.inducing anger

　　53.The word “ordeal” in Paragraph 3 probably refers to .

　　A.likelihood of promotionB.depressive experience

　　C.poor performanceD.unrealistic expectation

　　54.The annual performance reviews, to be effective, must focus on .

　　A.making employees aware of their company’s future goals

　　B.involving employees in assessing their own performance

　　C.encouraging employees to achieve better future performance

　　D.highlighting what responsibilities employees have failed in

　　55.The general attitude of the author toward Adam’s comic strip Dilbert is .

　　A.negativeB.positiveC.neutralD.unclear

　　Advertising is a form of selling. For thousands of years there have been individuals who have tried to 56 others to buy the food they have produced or the goods they have made or the services they can 57 .

　　But in the 19th century the mass production of goods 58 the Industrial Revolution made person-to-person selling inefficient. The mass distribution of goods that 59 the development of the railway and highway made person-to-person selling too slow and expensive.

　　Advertising as a 63 developed first and most rapidly in the United States, the country that uses it to the greatest 64 . In 1980 advertising expenditure in the U.S. exceeded 55 billion dollars, or 65 2 percent of the gross national product. Canada spent about 1.2 percent of its gross national product 66 advertising.

　　67 advertising brings the economics of mass selling to the manufacturer, it produces benefits for the consumer 68 . Some of those economies are passed along to the purchaser so that the cost of a product sold primarily through advertising is usually far 69 than one sold through personal salespeople. Advertising brings people immediate news about products that have just come on the market. Finally, advertising 70 for the programs on commercial television and radio and for about two thirds of the cost of publishing magazines and newspapers.
