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.

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.

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.

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.

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.

The text is most probably a ________.

A. science news report  B. book review

C. newspaper ad    D. science fiction story

PART FOUR   WRITING (45%)

How can you make a million dollars in one month? I’m sure I am going to get the   【小题1】  of many readers with this question. The    【小题2】   news is that you are not going to make a million dollars in one month    【小题3】   you win the lottery (彩票) or some prize.
We all want to be millionaires. However, if you try to find out how they become   【小题4】  rich, you will learn that they worked very    【小题5】  for the money. That is what most   【小题6】  have had to do, including Bill Gates and Andrew Carnegie, and they often went   【小题7】  hardships before they succeeded    【小题8】   .
There are many reasons why the millionaires have made it   【小题9】    for themselves. In this article, I am going to    【小题10】 passion (热情) which I think is the most    【小题11】   quality to have in order to succeed. I am sure that if one was to   【小题12】   the people who made millions in their lifetime, this would be found in all of them.
Take J.K Rowling for    【小题13】  . Her first Harry Potter was sent to twelve publishing houses, all of which    【小题14】  to publish it. A year later, she was finally given the chance by a small    【小题15】 , which paid 15.000. and the  【小题16】 from that company was that she should get herself a job since she had little  【小题17】   of making a living by writing children’s books. If you want to make a million dollars, find something that    【小题18】   you really passionate (热情的) and work hard at it. It doesn’t    【小题19】   what it is. Let me know how you    【小题20】   !
