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 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, 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(晶体结构) 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 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 applied.
B. to introduce nuclear batteries can be safely used.[来源:Z.xx.k.Com]
C. to describe a nuclear-powered system.
D. to introduce various energy sources.
3. Liquid semiconductor is used to _________.
A. get rid of the radioactive waste
B. test the power of nuclear batteries.
C. decrease the size of nuclear batteries
D. reduce the damage to lattice structure.
4. According to Jae Kwon, his nuclear battery _______.
A. uses a solid semiconductor
B. will soon replace the present ones.
C. could be extremely thin
D. has passed the final test.
5. The text is most probably a ________.

GAN Xiaolin, 18, only gets half a day __1.__ school every week since the Hubei student started senior high school．Every day, he takes core （核心的） courses from 7:10 am to 10:30 pm．

Gan is a typical Chinese student, as shown m a recently released survey．The new survey, which was __3.__ by the China Youth and Children Research Center and other foreign institutions, polled（调整） about 4,000 high school and vocational school students in China, Japan, the United States and South Korea．

The five biggest frustrations listed by all the young people were: an over-busy school life, an empty_4.__ life, dissatisfaction with their appearance, a lack of time for exercise and friends, and no spare money．

Although some of the teenage problems were y-niversai, there were big _ _5._ between the students when it came to the time they spent on sehoolwork．

For example, Chinese students spent the most time at school and on homework．Nearly 80 percent of them spent at least eight hours a week in school, and 56．7 percent spent two or more hours on their homework．By_6., only about 25 percent of US students, 20,5 percent of Japanese students, and 15 percent of Korean students had more than two hours of homework each night．

The responses from the Chinese students also _7._ significantly from their peers （同龄人）

in the other three countries when asked about their life goals．

Only 16．7 percent of Chinese students said that they didn't __8._ much about their future, while the figure for that category was 72．4 percent for US students, 59．1 percent for the Japanese and 58．2 percent for the South Koreans．The _9. found that Chinese students were more motivated than the other students to work hard for a better life．
