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 / nanoelectromechanreal 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.

36. 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.

37. Jae Kwon gave examples in Paragraph 4_________.

A. to show chemical batteries are widely applied.

B. to introduce nuclear batteries can be safely used.

C. to describe a nuclear-powered system.

D. to introduce various energy sources.

38. 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.

39. 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.

40. The text is most probably a ________.

A. science news report B. book review

C. newspaper ad D. science fiction story

四、阅读表达

Your schooldays should be some of the best and happiest days of your life. How can you gain the most from them, and ensure you do not waste this wonderful opportunity to learn.

〔1〕Be positive about school! Don't say things are difficult or boring. Be interested in school-life and your school subjects. Join in lots of activities. Be quick to put your hand up. Go round the school with a big smile.

〔2〕Expect to work. School is not a holiday camp. If you are not working, you are not learning, and you are wasting your time at school. Teachers cannot make everything enjoyable.

(3〕Keep fit. If you do not eat a good breakfast, you will be thinking about food in class. If you go to bed late and do not have enough sleep, you will be sleepy in class. Play some sports to keep your body strong.

〔4〕__________________________. Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get back in front. You cannot finish a race if you rest all the time.

〔5〕Don't be too disappointed if things sometimes go badly. Everyone fails some

五、话题写作

Nowadays, more and more people show their interest in English, because English plays a role as an international language .However, some of them are worried about their spoken English. They don’t think their English is standard enough to make them have a good communication with foreigners.

In my opinion, it is quite normal for people to have this kind of worry .After all we are not native English speakers, besides some times we speak English with strong accent. But as is known to us all, people even from English –speaking countries, speak quite differently.

Therefore as long as we practice speaking, listening and reading constantly, we can improve our oral English and only in this way can we communicate the foreigners well.
