When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.
These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society,” said George Vaillant, the psychologist (心理学家) who made the discovery. “And because they felt good about themselves, others felt good about them.”
Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.
The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.
Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn’t everything. As Tolstoy once said,
“One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one’s work.” 28. What do we know about John? A. He enjoyed his career and marriage. B. He had few childhood playmates. C. He received little love from his family. D. He was envied by others in his childhood. 29. Vaillant’s words in Paragraph 2 serve as _____. A. a description of personal values and social values B. an analysis of how work was related to competence C. an example for parents’ expectations of their children D. an explanation why some boys grew into happy men
30. What does the underlined word “sharp” probably mean in Paragraph 4? A. Quick to react. B. Having a thin edge. C. Clear and definite. D. Sudden and rapid. 31. What can be inferred from the last paragraph? A. Competent adults know more about love than work. B. Emotional health is essential to a wonderful adult life. C. Love brings more joy to people than work does. D. Independence is the key to one’s success.
D
Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated(展示) a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord(脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that
interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories：communication，and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.
32. How did Tavella operate the wheelchair in the laboratory?
A. By using his mind. B. By talking to the machine.
C. By moving his hand. D. By controlling his muscles.
33. Which of the following shows the path of the signals described in Paragraph 5?
A. scalp→computer→cap→wheelchair B. computer→cap→scalp→wheelchair C. scalp→cap→computer→wheelchair D. cap→computer→scalp→wheelchair
34. The team will test with real patients to ．
A. make profits from them B. learn about their physical condition C. make them live longer D. prove the technology useful to them
35. Which of the following would be the best title for the text?
A. Switzerland, the BCI Research Center
B. New Findings about How the Human Brain Works C. BCI Could Mean More Freedom for the Disabled D. Robotic Vehicles Could Help to Cure Brain Injuries 第二节(共5小题;每小题2分，满分10分)

Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：
Schedule yearly exams. 36 Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.
Protect against UV rays (紫外线). Long term stay in the sun creates risk to your eyes. No matter what the season is, it’s extremely important to wear sunglasses. 37
Give your eyes a break. Two thirds of Americans spend up to seven hours a day using computers or other digital products. 38 Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20second break and look at something 20 feet away.
39 As part of a healthy diet, eat more fruits and vegetables each day. Vitamins C and E help protect eyesight and promote eye health.
Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. 40 Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.
A．Eat your greens. B．Eye care should begin early in life.
C．They can properly protect your eyes. D．Stay in good shape by taking more vitamins. E．Parents usually don't care about their own eyesight. F．Always follow the doctor's advice for appropriate wear. G．This frequent eye activity increases the risk for eye tiredness. 第三部分 英语知识运用（共两节，满分45分）

Even though it was only October, my students were already whispering about Christmas plans. With each passing day everyone became more 41 , waiting for the final school bell. Upon its 42 everyone would run for their coats and go home, everyone except David.
David was a small boy in ragged clothes. I had often 43 what kind of home life David had, and what kind of mother could send her son to school dressed so 44 for the cold winter months, without a coat, boots, or gloves. But something made David 45 . I can still remember he was always 46 a smile and willing to help. He always 47 after school to straighten chairs and mop the floor. We never talked much. He 48 just smile and ask what else he could do ,then thank me for letting him stay and slowly 49 home.
Weeks passed and the 50 over the coming Christmas grew into restlessness until the last day of 51 before the holiday break. I smiled in 52 as the last of them hurried out the door. Turning around I saw David 53 standing by my desk.
“I have something for you” he said and 54 from behind his back a small box. 55 it to me, he said anxiously, “Open it.” I took the box from him, thanked him and slowly unwrapped it. I lifted the lid and to my 56 saw nothing. I looked at David’s smiling face and back into the box and said, “The box is nice, David, but it’ s 57 .”
“Oh no, it isn’t” said David. “It’s full of love, my mum told me before she died that love was something you couldn’t see or touch unless you know it’s there.”
