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 high energy density (密度),” said Jae Kwon, assistant professor of electrical and computer eng ineering 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, presently the size and thickness of a penny, intended to power various micro/nanoelectromechanical systems(M/NEMS). 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 belie ve 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 s ize and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair.1. Which of the following is true of Jae Kwon?A. He teaches chemistry at MU.B. He developed a chemical battery.C. He is working on a nuclear energy source.D. He made a breakthrough in computer engineering.2. Jae Kwon gave examples in Paragraph 4 .A. to show chemical batteries are widely appliedB. to indicate nuclear batteries can be safely usedC. to describe a nuclear-powered systemD. to introduce various energy sources3. Liquid semiconductor is used to .A. get rid of the radioactive wasteB. test the power of nuclear batteriesC. decrease the size of nuclear batteriesD. reduce the damage to lattice structure4. According to Jae Kwon, his nuclear battery .A. uses a solid semiconductorB. will soon replace the present onesC. could be extremely thinD. has passed the final test5. The text is most probably a .A. science news reportB. book reviewC. newspaper adD. science fiction story【参考答案】1--5 、CBDCA科普学问类阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
