Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some degree our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person's intelligence are fixed at birth, but 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 degree 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(随机地) from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical (完全相同的) 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 would 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 degrees of intelligence.

A study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities (个性) and food experiences. “One week later,” Loftus says, “we told those people we'd fed their answers into our smart computer and it came up with an account of their early childhood experiences.” Some accounts included one key additional detail (细节): “You got sick after eating strawberry ice-cream.” The researchers then changed this detail into a manufactured (人为促生的) memory through leading questions—Who were you with? How did you feel? By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it.
When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it's not that easy. False memories appear to work only for foods you don't eat on a regular basis. But most important, it is likely that false memories can be implanted (灌输) only in people who are unaware of the mental control. And lying to a patient is immoral, even if a doctor believes it's for the patient's benefit.
Loftus says there's nothing to stop parents from trying it with their overweight children. “I say, wake up—parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that's a more moral lie. Decide that for yourself.”
72. Why did Loftus ask the volunteers to answer some questions?
A. To improve her computer program. B. To find out their attitudes towards food.
C. To find out details she can make use of D. To predict what food they'll like in the future.

75. What is the biggest concern with the method?
A. Whether it is moral. B. Who it is best for.

While parents, particularly mothers, have always been attached to their infants (婴儿), societal conditions frequently made this attachment difficult to maintain (保持). First of all, the high infant death rate in the premodern times meant that such attachments often ended in hopelessness. Perhaps to prevent the sadness that infant death caused, a number of societal practices developed which worked against early attachment of mother and child.
One of these premodern attachment-discouraging practices was to leave infants unnamed until they had survived into the second year. Another practice that discouraged maternal (母亲的) attachment was tightly wrapping (包裹) infants. Wrapping effectively prevented the close physical interactions like stroking (抚摸) and kissing that are so much a part of modern mothers' and fathers' affection for their infants.
A third practice which had the same distancing effect was wet-nursing. Breast-feeding (母乳哺育) was not popular among the well-to-do in the early modern times; infants were often fed by wet nurses hired for the purpose. In some places, such as nineteenth-century France, city infants were sent to wet nurses in the country. Often a wet nurse would feed her own child first, leaving little milk for the city infant—who, in many cases, died. In Rouen, the death rate for children sent to a wet nurse was 35 percent.

Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. These mountains are a splendid sight when viewed form the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure (基础设施) that must be maintained.
Unfortunately, these systems are starting to break down. It’s not just in Yosemite but in national parks around the nation.
Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The Park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with.
Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park Service had to send water trucks to provide water for the visitors. Last month pipes almost broke again and roads had to be closed for a while.
Why hasn’t the National Park Service kept up the park repairs? There is a lack of money. The United States has 378 monuments, parks, and wilderness areas. Between three and four billion dollars are needed for repairs.
Yosemite is one national park that does have money for repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park.
A sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowded park.
65.According to the text, the mountains in Yosemite look most splendid when they are appreciated from ______.
A. the bottom of the valleys B. the top of the mountains
C. the side of the mountains D. the edge of the valleys

visitors because ______.
A. their transport management needs improving
B. they spend too much on their service systems
C. their service systems frequently go out of order
D. they need help from environmental organizations
67.The main problem of Yosemite National Park is its ______.
A. rundown water pipes B. overcrowdedness
C. lack of money D. narrow roads
68. According to the text, the Sierra Club is most likely to be ______.
A. an environmental groupB. an information center
C. a travel serviceD. a law firm
In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity. Others say that competition is bad; that it sets one person against another; that it leads to unfriendly relationship between people.
I have taught many children who held the belief that their self-worth relied（依赖）on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit(追求)of success, the development of many other human qualities is sadly forgotten.
However, while some seem to be lost in the desire to succeed, others take an opposite attitude. In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: “ I may have lost, but it doesn’t matter because I really didn’t try.” What is not usually admitted by themselves is the belief that if they had really tried and lost, that would meana lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of true competitors who try to prove themselves. Both are based on the mistaken belief that one’s self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve(缓解) can we discover a new meaning in competition.

D. those who rely on others most for success
74. What is the similar belief of the true competitors and those with a “desire to fail”?
A. One’s worth lies in his performance compared with others.
B. One’s success in competition needs great efforts.
C. One’s achievement is determined by his particular skills.
D. One’s success is based on how hard he has tried.

“My kids really understand solar and earth-heat energy,” says a second-grade teacher in Saugus, California. “Some of them are building solar collectors for their energy course.” These young scientists are part of City Building Educational Program (CBEP), a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading, writing and math skills, and more.
The children don’t just plan any city. They map and analyze（分析）the housing, energy, and transportation requirements of their own district and foretell its needs in 100 years. With the aid of an architect（建筑师）who visits the classroom once a week, they invent new ways to meet these needs and build models of their creations. “Designing building of the future gives children a lot of freedom,” says the teacher who developed this program. “They are able to use their own rich imagination and inventions without fear of blame, because there are no wrong answers in a future context. In fact, as the class enters the final model-building stage of the program, an elected ‘official’ and ‘planning group’ make all the design decisions for the model city, and the teacher steps back and becomes an adviser.”
CBEP is a test of activities, games and imitations that teach the basic steps necessary for problem-solving: observing, analyzing, working out possible answers, and judging them based on the children’s own standards.
63. The Program is designed ______________.
A. to direct kids to build solar collectors
B. to train young scientists for city planning
C. to develop children’s problem-solving abilities
D. to help young architects know more about designing
64. An architect pays a weekly visit to the classroom ____________.
A. to find out kids’ creative ideas B. to discuss with the teacher
C. to give children lectures D. to help kids with their program
65. Who is the designer of the program?
A. An official. B. An architect. C. A teacher.D. A scientist.
66. The children feel free in the program because ______________.
A. they can design future buildings themselves
B. they have new ideas and rich imagination
C. they are given enough time to design models
D. they need not worry about making mistakes
