题目列表(包括答案和解析)

Read the following four passages.Each passage is followed by several questions or unfinished statements.For each of them there are 4 choices marked A, B, C and D.Choose the one that fits best according to the information given in the passage.

  Batteries can power anything from small sensors to large systems.While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves.University of Missouri(MU)researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

  “To provide enough power, we need certain methods with energy density(密度),” said Jae kwon, assistant professor of electrical and computer engineering at MU.“The radioisotope(放射性同位素)battery can provide power density that is much higher than chemical batteries.”

  Kwon and his research team have been working on building a small nuclear battery, recently the size and thickness of a penny, intended to power various micro/nano-electromechanical systems(M/NEWS).Although nuclear batteries can cause concerns, Kwon said they are safe.

  “People hear the word ‘nuclear’ and think of something very dangerous,” he said.“However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

  His new idea is not only in the battery's size, but also in its semiconductor(半导体).Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.

  “The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶格结构)of the solid semiconductor,” Kwon said.“By using a liquid semiconductor, we believe we can minimize that problem.”

  Together with J.David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery.In the future, they hope to increase the battery's power, shrink its size and try with various other materials.Kwon said that the battery could be thinner than the thickness of human hair.

Li Denghai, with his muddy boots and tanned(晒黑的) face, may not look like he is one of China’s famous agricultural pioneers. But the 61-year-old man from Shandong Province has made scientific breakthroughs(突破), which made great contributions to China’s food security(安全). His main work has been in achieving the higher output of corn production.

Li, who holds the world record for the highest output of summer corn, once says, “Corn has a life; it sings and dances. If you listen clearly, it can speak to you.” He started his research in 1969 when he was 20 and just dropped out of a high school. He then read an article which pointed that corn output per mu in the USA was six times higher than that in China. He was shocked and set out to work on just a small piece of land round the clock to see if he could increase the output. He often went to the field with a flashlight late at night, if he had been away during the day. By careful nurturing (照料) he managed to double the output.

Li Denghai was awarded the “China Award for Significant Contribution to the Maize (玉米) Industry” in 2005, and the same year the company named after his own name came into the market on the Shenzhen Stock Exchange. Li, however, is never happier than when he is in the middle of his cornfields. “I can forget my tiredness when talking to my corns,” he says.

60. When Li Denghai began the study of corn,    .

   A. he just graduated from an ordinary high school

   B. he was shocked that the corn output in China was so low

   C. he was only in his thirties

   D. he wasn’t really fond of his work

61. The underlined phrase “round the clock” means   .

   A. day and night  B. sooner or later     C. face to face     D. now and then

62. From Mr. Li’s words in this passage, we can learn that   .

   A. he is not good at communicating with people

   B. he is too tired to go to the corn fields

   C. he talks to his corn when feeling lonely

   D. he loves his career deeply
