Are some people born clever, and others born stupid? Or is intelligence developed by our environment and experience? Strangely enough, the answer to these questions is yes. To some extent, person’s intelligence is fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随意地) from the population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is  boring. We should soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
68. The writer is in favor of the view that man’s intelligence is given to him
A. at birth                          B. through education
C. both at birth and through education    D. neither at birth nor through education
69. If a child is born with low intelligence, he is unlikely to      
A. become a genius so long as he or she works hard enough
B. still become a genius if he should be given special education
C. go beyond his intelligence limits even in rich surroundings
D. never reaches his intelligence limits in his life
70. The example of the twins going to a university and to a factory separately shows
A. the importance of their intelligence      
B. the role of environment on intelligence
C. the importance of their positions        
D. the part that birth plays
71. What can be the best title for the text?
A. Surroundings                           B. Intelligence
C. Dependence on Environment              D. Effect of Education

B
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it’s a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命)can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇帝的)family being a good example, have hereditary(遗传的)diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. Scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture(生产)human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
60. What does "these two killers" in the second paragraph refer to?
A. Gene technology and another treatment of the two diseases.
B. The two murderers who killed the cloned baby.
C. The two diseases of cancer and heart disease.
D. Hereditary diseases and cancer.
61. What’s the main idea of the third paragraph?
A. Gene technology can help people to give birth to a baby.
B. Gene technology can be used to clone human babies.
C. How gene technology can be used to treat hereditary diseases.
D. Gene technology can solve all the problems of the English imperial family.
62. In what way can gene technology help to treat hereditary diseases?
A. Gene technology helps people with hereditary diseases to live longer.
B. Using gene technology, scientists find the wrong gene and correct it.
C. Using gene technology, human babies can be cloned.
D. Doctors can cure cancer and heart disease with the help of gene technology.
63. What is the main purpose of writing this passage?
A. Expressing the writer's idea that gene technology will benefit people.
B. Telling people the advantages and disadvantages of gene technology.
C. Telling the readers that gene technology will not benefit people.
D. Explaining that gene technology will also do harm to the humanity.

A Subway Superhero
Wesley Autrey can't fly, but he is still being called a real-life Superman! Last week, the brave 50-year-old rescued Cameron Hollopeter, 20, from being hit by a train. The train was entering a subway station in New York City. The young man had fallen from the station's platform and onto the train tracks a few feet below.
Autrey, a construction worker and Navy veteran(老兵), was with his two young daughters when he saw Hollopeter fall. Autrey made a quick decision and jumped onto the tracks. He then rolled himself and Hollopeter into a gap, or opening, between the rails. Autrey used his own body to protect the young man.
Five of the train’s cars passed over the two before stopping completely. The two men were both unharmed. Hollopeter’s stepmother, Rachel Hollopeter, called Autrey an “angel”. Autrey visited the New York Film Academy student in the hospital on Wednesday.
For his bravery, Autrey was given a hero's welcome at City Hall. New York City Mayor Michael Bloomberg presented Autrey with the Bronze Medallion (铜奖章）. It is the city'’s highest award for achievements by its citizens. Mayor Bloomberg called Audrey “ a great man-a man who makes us all proud to be New Yorkers."
After the ceremony at City Hall, a limousine (豪华轿车)took Autrey to a meeting with multimillionaire businessman Donald Trump. Trump awarded Autrey with $ 10,000. The heroic father also received $ 5,000 from the New York Film Academy, a trip to Disney World, and one year of free sub way rides.
Even after all this attention; Autrey still doesn't see himself as a Superman.” I did it out of a split-second reaction," Autrey said on CBS' The Early Show. "And if I had to do it again, I probably would."

At a certain time in our lives we consider every place as the possible site for a house. I have thus searched the country within a dozen miles of where I live. In imagination I have bought all the farms, one after another, and I knew their prices.
The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the dollars and sold him the farm for just what I gave for it.
The real attractions of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相邻) on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.
I was not really troubled by the loss. I had always had a garden, but I don’t think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted(无牵无挂). It makes but little difference whether you own a farm or not.
57.What do we know about the author?
A. He wanted to buy the oldest farm near where he lived.
B. He made a study of many farms before buying.
C. He made money by buying and selling farms.
D. He had the money to buy the best farm in the country.
58.Why did the author want to buy the farm in a hurry?
A. He was afraid the owner might change his mind.
B. He hoped to enlarge the forest on the farm.
C. He wanted to keep the farm as it was.
D. He was eager to become a farm owner.
59.The underlined words “the loss” in the last paragraph refer to _____?
A. the money the author lost in buying the farm
B. the sale of the garden in the Hollowell place
C. the removal of the trees around the house
D. the failure to possess the Hollowell place
60.What does the author believe as important in life?
A. To own a farm               B. To satisfy his needs
C. To be free from worries.       D. To live in the countryside.

It’s 2035.You have a job, a family, and you’re about 40 years old. Welcome to your future life.
Getting ready for work, you pause in front of the mirror, “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronic are rearranged(重新设置) in your shirt to change its color. Looking into the mirror, you find it hard to believe that you are 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You’re not even middle-aged.
As you go into the kitchen and prepare to pour cereal(谷类) breakfast into a bowl, you hear: “To lose weight, you shouldn’t eat that,” from your shoes. They read the tiny electronic code on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appear on the counter as kitchen checks its food supplies. 
“Ready for your trip to space. You ask your son and daughter.” In 2005 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trips or longer vacation. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical advices, vaccination shots(注射疫苗) are a thing of the past. Ordinary foods contain specific vaccines. With the berries in their mouths, the kids head for the front door.
It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot(自动驾驶).” You command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video films rather than read it.
54.What changes the color of your shirt?
A. The mirror     B. The shirt itself    C. The counter    D. The medicine
55.The strawberries the children eat serve as _____?

Astronauts’ meals have come a long way from the free-dried powders and semi-liquid pastes of decades ago, now US scientists want to grow vegetables in mini-greenhouses on the moon.
Scientists say they are looking forward to a time when residents of future lunar or even Martian outsteps will be able to dine on fresh vegetables. Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers—and eventually food-oh the moon.
This is a sealed greenhouse that looks like a bell jar encased in a 46-cm triangular aluminum frame. It is designed to safely land a laboratory plant on the lunar surface, and protect it while it grows.
The miniature greenhouse is to be launched into space by Odyssey Moon Ltd, a participant in the Google Lunar X Prize. This competition offers $20 million to any entrant who can launch, hand and operate a rover on the lunar surface.
Paragon officials say future testing of the “Lunar Oasis” will be driven by Odyssey’s flight schedule, which will not happen until 2012 at the earliest.
When it does lift off the greenhouse will contain the seeds of Brassica, a hardy plant related to Brussels sprouts and cabbage. Because Brassica goes from seed to flower in just 14 days, it can complete its life cycle in single lunar night.
“Coloizing the Moon or Mars seems so far away, but it is important that we do this research now, ” Paragon president Jane Poynter said.
“It takes a long time to get a lot of research, and to get integrated, reliable efficient systems before colonists move in,” she said.

Depression （抑郁症）is a serious problem today. Depression causes workers to be unproductive, causing companies and countries to lose billion of dollars. One expert says that depression is like cancer because it is “widespread, costly and deadly”. Depression hits one person in five around the world.
Although people have believed depression to be a problem among the rich and educated, studies show that depression is a problem among everyone. Over any six-mouth period, between five to seven percent of the world’s population will be suffering from a serious depression.
Suicide （自杀）rates among people suffering from the disease in its extreme, or clinical form were 80 percent higher that in the population at large, and suffers were four times more likely to have heart attacks. People who suffer from depression often have problems sleeping, getting up on time, and doing work productively.
Depression, which researchers agree has its origin in the genes（基因）, brings loss of of confidence and ability to concentrate-making it possible for employees and managers to work efficiently.
Depression is made more serious in China by Chinese’s by Chinese inability to face it. Many people believe that depressed people are either weak or lazy. Besides, there is no good treatment, with few specialists available.
“Most patients in China just don’t get help,” a Chinese doctor says. “In my hospital, I have to see 30 or 40 patients in a morning, and just have time to say ‘Hello, how do you feel?’”
In Western countries, people are not afraid to admit that they have depression, but most do not tell it to their boss, because they fear that their boss would fire them.
“In my experience, aging bosses are the most tilling to admit they have it, because they feel the most secure about themselves,” an American doctor says.
Hopefully, in the near future, people around the world will be able to admit that they have depression so that they can get the right treatment.

A．very unconfident and often absent-minded   
B．easy to avoid being hit by heart attacks
C．working efficiently and productively
D．either weak or lazy
51．Depression becomes more serious in China because of _________.
A．the understanding of the problem   B．the lack for treatment and doctors

Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unequally heats the surface of the Earth. As hot air rises, cooler air moves in to fill the gap. As long as the sun shines, the wind will blow. And as long as the wind blows, people will manage it to power their lives.
Ancient sailors used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to make electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small part of the world's energy.
Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These devices look like giant airplane propellers(螺桨)on a stick. The wind spins the blades, which turn a shaft connected to a generator.
The biggest wind turbines generate enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines set up in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments decrease tax to encourage wind-energy development.
Some people think wind turbines are ugly and complain about the noise the machines make. The slowly rotating blades(螺旋风片) can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also changeable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is increasing sharply. Globally, generation more than quadrupled(四倍) between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind
63. According to the passage, which of the following statements is true?
A. The rotating blades can kill as many birds as high-rise buildings do
B. Single families are not encouraged to build turbines.
C. The USA produces more wind power than any other country in the world.
D. The noise the turbines make may discourage people from building them.
64. The underlined word “generator” in the third paragraph probably means_______.
A. 电动机                 B. 发电机                    C. 机翼                       D. 飞机引擎
65. If the USA wants to build wind turbines in an area with 30,000 homes, how many
should they build at least?
A. 50.                          B. 150.                         C. 250.                         D. 200.
66. All the following are the advantages of wind energy EXCEPT that_________.
A. it is environmentally friendly                        B. it is free to build and operate
C. the government supports it                                   D. the energy is clean and renewable

　A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
　Research from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
　Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
　But questions have been raised about sunscreen and whether it may have the opposite effect by allowing people to remain exposed to the sun longer without burning.
　The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer---are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
　The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
60．The underlined word “flaws” in the 2nd paragraph most probably means _________.
A．evidences         B．facts         C．faults         D．failures
61．People with fair skin and freckles ________.
A．seldom use sunscreen　　　　　　         B．are more in danger of skin cancer
C．can be free from the harm of the sun　　     D．often expose themselves to the sun
62．We can learn from the passage that _________.
A．sunscreen users get skin cancer more often
B．the volunteers have proved the effect of the sunscreen
C．the new study has based on the experiences of volunteers
D．the number of skin cancer patients is increasing in America
63．Which of the following is the best title of the passage?
A．Sunscreen to Prevent Skin Cancer　      B．Sunscreen to Increase Skin Cancer
C．Skin Cancer Caused by Sunscreen　      D．Skin Cancer Caused by Freckles
