閱讀下面短文并回答問題,然后將答案寫到答案卡相應(yīng)的位置上。

[1] Scientists in the United States are working on a technology that uses human energy to power devices like cell phones, laptop computers, and GPS systems.

[2] Tom Krupenkin, who teaches electrical engineering at the University of Wisconsin and his team want to reduce dependence on costly and polluting batteries. Instead of using batteries for power, they have turned to human beings and have placed a device in a shoe that collects and stores energy from human motion and turns it into electricity. One part of this device is an energy harvester. It has two small containers filled with thousands of very small drops of liquid. These droplets get pushed back and forth as a person walks and can directly convert it into electric power. Output of this energy is stored in a regular rechargeable tiny battery of the style that we have in cell phones.

[3] The team has also developed a system to permit use of the stored energy by common mobile devices. It does not require connections with wires, and can be used to create a wireless signal. A cell phone that uses the wireless “hotspot” from the shoe would use much less power if   __________   a wireless telephone network. The devices are about the size of a credit card. Professor Krupenkin says the system is always powered. So unlike a traditional battery, this energy harvester never needs to be recharged.

[4] The professor says he does not expect this invention to replace traditional batteries. But it will help reduce dependence on them. He says there are a huge number of possible uses for this technology. Professor Krupenkin thinks the technology would be useful for people in rural areas where there is no electrical power.

[5] He stresses that it makes a lot of sense for people who depend on devices like mobile phones and laptop computers. And he says the technology could be used by soldiers who must carry battery–powered electronic devices into difficult territory(地區(qū)).

 Mice fed junk food for nine months showed signs of developing the abnormal brain tangles strongly associated with Alzheimer's disease, a Swedish researcher said on Friday.

“On examining the brains of these mice, we found a chemical change not unlike that found in the Alzheimer brain,” Susanne Akterin, a researcher at the Karolinska Institutet's Alzheimer's Disease Research Center, who led the study, said in a statement.

“We now suspect that a high intake of fat and cholesterol (膽固醇) in combination with genetic factors ... can adversely affect several brain substances, which can be a contributory factor in the development of Alzheimer’s.”

Alzheimer’s disease is incurable and is the most common form of dementia (癡呆) among older people. It affects the regions of the brain involving thought, memory and language.

While the most advanced drugs have focused on removing clumps of βamyloid protein(β淀粉蛋白) that forms plaques in the brain, researchers are also now looking at therapies to address the toxic tangles caused by an abnormal build-up of the protein tau (T形蛋白).

In her research, Akterin focused on a gene variant (基因突變) called apoE4, found in 15 to 20 percent of people and which is a known risk factor for Alzheimer’s. The gene is involved in the transport of cholesterol.

She studied mice genetically engineered to imitate the effect of the variant gene in humans, and which were fed a diet rich in fat, sugar and cholesterol for nine months -- meals representing the nutritional content of fast food.

These mice showed chemical changes in their brains, indicating an abnormal build-up of the protein tau as well as signs that cholesterol in food reduced levels of another protein called Arc involved in memory storage, Akterin said.

“All in all, the results give some indication of how Alzheimer's can be prevented, but more research in this field needs to be done before proper advice can be passed on to the general public,” she said.

61. What did Susanne Akterin find in her research?

   A. Signs of developing the abnormal brain disorders.

   B. The abnormal brain disorders because of junk food.

   C. Akterin’s disease linked with junk food.

   D. The same chemical change in the Alzheimer brain.

62. What is Susanne Akterin’s idea about Alzheimer’s disease?

   A. She thinks it’s caused by fat and cholesterol (膽固醇) with genetic factors.

   B. She doesn’t believe that it’s caused by fat and cholesterol (膽固醇) with genetic factors.

   C. She doubts whether it’s caused by fat and cholesterol (膽固醇) with genetic factors.

D. She believes junk food causes mice to be abnormal.

63. Which is NOT the sign of dementia among older people?

   A. Often forgetting things               B. Often repeating the same words.

   C. Often being weak                   D. Unable to understand other people.

64. Which of the following is true according to the passage?

   A. It’s easy to cure Alzheimer’s disease.

   B. There’s no way to cure Alzheimer’s disease.

   C. Akterin has found Alzheimer’s disease.

   D. Akterin removedβamyloid protein (β淀粉蛋白).

65. What does Akterin’s experiment tell us?

   A. Alzheimer’s disease can be avoided.

   B. Alzheimer’s disease is incurable.

   C. Alzheimer’s disease can be cured.

   D. Mice are the same as humans.

The time of year a baby is born can shape what profession they will embark on in later life, a new study has suggested. Being born in a certain month appears to indicate the statistical likelihood of what job a person will end up with, the study by the Office for National Statistics found.

Researchers have uncovered that the month in which babies are born could also affect everything from intelligence to length of life. A child born in December is more likely to become a dentist while someone whose birthday falls in January will tend to a debt collector, they found.

A February birth appears to increase the chances of being an artist while March babies appear to go on to become pilots. Meanwhile, April and May are said to have a fairly even spread of professions, births in the summer months mean a much lower chance of becoming a high-earning football player, doctor or dentist. The study was derived by researchers who analyzed the birth months of people in 19 separate occupations using information from the last census, the Daily Mail reported. Although these trends may be difficult to explain, correlations between birth months and specific health problems have a scientific basis.

   Spring babies are at greater risk of illnesses including schizophrenia, Alzheimer’s disease, asthma and autism. They may also be less clever than classmates born in other parts of the year.

56. What does the underlined phrase “embark on” refer to?

A. land on                            B. keep in touch with          

C. be occupied in                      D. resign from

57. According to the researchers, a child born in March is likely to become_______.

A. a debt collector                     B. a pilot             

C. a dentist                           D. an artist

58. We can learn from the text that______.

A. the month babies are born could only affect his intelligence and length of life    

B. people born in the summer months are more likely to get highly paid

C. Spring babies may have the bigger chance to get ill     

D. the choice of profession for April and May is very narrow

59. What can be included from the passage?

A. There exist connections between birth date and occupations        

B. The fate has been already decided when people are born       

C. People born in Autumn would be more successful than those born in Spring

D. The time of year one is born decides which specific health problems one has

60. According to the passage, the following statements are true except ______?

A. March babies are more likely to be pilots when grown up

B. If born in December, a person is more likely to become a dentist.

C. As in the research, health problems have something to do with birth months.

D. Summer babies may be less clever than those born in other seasons.

   The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life-style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.

  A multitude of factors, both inherited and environmental, influence the development of health-related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health-related behavior is usually one of personal choice. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Crapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical (統(tǒng)計的) probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity (長壽).

46. The concept of personal choice concerning health is important because _______.

  A. wrong decisions could lead to poor health

  B. it helps raise the level of our medical knowledge

  C. it is essential to personal freedom in American society

  D. it helps cure most illnesses

47. To “l(fā)ive a completely sedentary life-style” (Para.1) in the passage means _________.

  A. to “l(fā)ive a decent life”                  B. to “l(fā)ive an inactive life”

  C. to “l(fā)ive a life of vice”                 D. to “l(fā)ive a life with complete freedom”

48. Sound personal health choice is often difficult to make because __________.

  A. few people are willing to trade the quality of life for the quantity of life

  B. people are usually influenced by the behavior of their friends

  C. current medical knowledge is not enough yet

  D. there are many factors influencing our decisions

49. To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crapo to _______.

  A. deliberately ending one’s life             B. improving the quality of one’s life

  C. limiting one’s personal health choice      D. breaking the rules of social behavior

50. According to Fries and Crapo sound health choices should be based on ______.

  A. personal decisions                      B. statistical evidence

C. friends’ opinions                       D. society’s laws

   Brenda Bongos was a happy, artistic girl. She had one big ambition — to play the drums in a band. But one big obstacle lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy.

    One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut.

    With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit(成套設(shè)備) and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child.

    It wasn’t long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band.

    Years later, when asked how she had achieved all this, she thought for a moment, and said: “If those old people next – door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened.”

41. Why did Brenda try to play in the strangest places?

   A. Because she didn't want others to hear her play.

42. Brenda started to give concerts _______.

   A. after she practiced in her space bubble

   B. when she became part of the unique space journey

   C. after she became a real musical astronaut

   D. when people came to see her in the space bubble

43. Brenda became famous because _______.

   A. she made a space suit                    B. she became a real musical astronaut

   C. she played drums in her space bubble       D. she played drums in a band

44. Which of the following can be used to describe Brenda?

   A. kind, hardworking and clever              B. brave, kind and hardworking

   C. lovely, brave and kind                    D. nervous, kind and clever

45. We can draw a conclusion from the passage that: “_______”.
