ery’s size, but also in its semiconductor(半導(dǎo)體). 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(晶格結(jié)構(gòu)) 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 the battery could be thinner than the thickness of human hair. of the following is true of Jae Kwon?A. He teaches chemistry at MU.B. He developed a chemical battery.C.

Researchers began reporting the benefits of family dinner about a decade ago, focusing mainly on how it affects children. Studies show that those families who eat dinner at least 3 or 4 times a week together, benefit in many ways. [2]Eating together helps families achieve open munication and build stronger and healthier relationships. Children have better grades at school and are better adjusted as teens and adults, and the entire family enjoys healthier nutrition. For many families, eating dinner together proves to be good and effective way to reduce the risk of youth rates of addiction, and helps to raise healthier children. It is also a great time to share the events of the day, discuss news and ideas and just be together and enjoy each other39。s pany. [3]During dinner time parents have better opportunity to show that they are for their children. Sitting at the same table and sharing meals is where and when parents can find out more about their children39。s school performance, daily activities and attitudes toward life. When parents have all this information they can better direct their kids toward positive things in life. They also have better chance to reduce the possibility that children will get involved with alcohol, tobacco, and illegal drugs. [4]However, family researchers say that the benefits of family dinner by no means can be considered as automatic. Parents can sit down to dinner with their kids every day and achieve nothing. ____________________ if there is too much arguing going on, if there is no meaningful conversation or, what is even worse, if there is just plain silence during gathering. 76.
