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 bat
tery. 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 thic
kness 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. cou
ld be extremely thin
D. has passed the final test.
5. The text is most probably a ________.

The pound new Library of Birmingham（LoB）will be the most visible sign of the way the city is accepting the digitalization（数字化）of everyday life.
Set to open in 2013, the £188m LoB is already beginning to tale shape next to the Birmingham Repertory Theatre, with which it will share some equipment.[来源:Z。xx。k.Com]
As digital media（媒介）is important to its idea. the project is already providing chances for some of the many small new local companies working at the new technologies.
Brian Gambles, the LoB project director, says it is about giving people the right tools for learning,“The aim is to mix the physical with the digital. Providing 24-hour services which can be used through many different ways. It is important to enable us to reach more people, more effectively.”
The digital library will, he says, be as important as the physical one, allowing the distant use of the services, making sure that it is never closed to the public.
Even before the LoB is complete, the public has been able to go online to visit the Virtual（虚拟的）LoB, designed by Baden, the Birmingham virtual worlds specialists. Not only have the public been able to learn about LoB, but the virtual one has also enabled those working on the LoB to understand the building and how it will work before it even opens.
Two other small Birmingham-based digital companies are working on the LoB projects. Substrat, a digital design company, is developing what it calls “enlarge reality” project. It is about the use of an exciting smart phone, an important part of the LoB which is in the early stages of development is an online library of figures of the city being built by a digital content company in Cahoots, in which users will be encouraged to add to and comment on the material.
Gambles says: “Technology will enable us to make the library’s content and services open to citizens as sever before.”

A.Because the systems can store users’ information B.Because many users have suffered loss after using them． C.Because it is thought to threaten users’ privacy． D.Because many reporters have shown the problem of the systems． 2. Allan Friedman believes that ________． A.wireless companies focus on personal privacy． B.people are forbidden to get access to private data at will C.phone companies may sell private information secretly D.customers may ask wireless companies to locate their tracking 3. What do we know from Paragraph 3? A． Location tracking information is stored online． B.Apple’s newest operating systems collect all kinds of information． C.Location tracking information may be uploaded to any iPhone． D.Apple’s newest operating systems may reveal the private information of users． 4.Which of the following statements is TRUE according to the passage? A.Apple denies that it tracks the location of users． B.The researchers may misunderstand the Apple’s systems．[来源:Z,xx,k.Com] C.The global positioning system is to blame for rogue applications． D.The iPhone can quickly find its location by using its user’s information．
