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.

Students at the Hogook Middle School in South Korea have a unique assignment：going    online to message boards and write positive，cheerful comments．Teachers and other adults     hope those comments will discourage others from leaving vicious(恶意的)and negative     remarks．This is one of the activities in a nationwide program called the Sunfull Movement．
Online attacks are an increasing problem in South Korea，one of the world’s most     connected  nations．The  National Police  Agency  receives tens  of thousands  of  complaints every year．but there is not much that can be done to stop it，since attackers seldom use    their real names．In the worst．cases，authorities say cyber—bullies(网络攻击have pressured     some  people to take their  own lives．That  is  why the  Sunfull  Movement’s  founder， Min Byoung'chul, a professor at Kunkuk University，began the program three years ago．
Min says research indicates ninny of the attackers are under the age of 30．“Young kids，they’re stressed out because of schoolwork．The．y have to prepare for their college entrance  examinations  and they just  write  whatever they  feel．That’s  one  of the  ways to     blow off their discontent and stress．”explained Min．
Student Kim Hee-joo，15, says she writes thank—you messages to friends，family and     teachers on her School’ s homepage．And when she sees people making bad comments about     famous people，she leaves nice messages，because when people see positive comments they     are more likely to stop saying bad things and change their attitude．
Teacher Kim Eun—young says Koreans do not really say “Thank you”or“J love you”     to friends or parents. But being not face一to一face, they feel more comfortable saying those kinds of things．She  also  says  violence  at the  school，both  online  and  offline，has decreased and students and teachers get along much better now．
61．What’s the aim of the Sunfull Movement?
A．To teach students how to make comments on the Internet·
B．To serve as a model for other nations by gaining experience．
C．To offer students suggestions on letting off their discontent and stress·
D．To stop cyber—bullying and create a positive atmosphere on the Internet·
62．Online attackers are mostly young people because———————·
A．they hate the internet society    B．they want to be famous
C．they are facing too much pressure D．they aye full of energy
63．Which of the following is true according to the text?
A．Network management in South Korea is bad．
B．Online attacks sometimes can make people kill themselves．
C．Police Agency’S work efficiency is low in South Korea．
D．Professor Min thinks cyber—bullies can be forgiven．    ’
64．It can be inferred from the 1ast paragraph that——·
A．People in South Korea tends to express themselves frankly
B．Koreans、sometimes aye not polite to their friends or parents
C．Students and teachers don't get along well in Korean schools
D．Changes have taken place since the school began the program
65．The best title of this passage probably is _______________．
A．Battle Cyber—Bullying with Positive Comments
B．Keep Away from Negative Remarks Online
C．Students in South Korea Face Much Pressure
D．A Remarkable Concern in South Korea

We know the famous ones—the Thomas Edisons and the Alexander Graham Bells—but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper (雨刮器)？ Shouldn’t we know who they are?

Joan Mclean thinks so. In fact, McLean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she’s developed a course on the topic. In addition to learning “who” invented “what”, however, McLean also likes her students to learn the answers to the “why” and “how” questions. According to McLean, “When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more willing to give inventing a try.”

Her students agree. One young man with a patent（专利）for an unbreakable umbrella is walking proof of McLean’s statement. “If I had not heard the story of the windshield wiper’s invention,” said Tommy Lee, a senior physics major, “ I never would have dreamed of turning my bad experience during a rainstorm into something so useful.” Lee is now considering to sell his patent to an umbrella producer.

So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn’t be a built-in device(装置) for cleaning the window. Still wondering about this when she returned home to Birminghan, Alabama, Anderson started drafting out solutions. One of her ideas, a lever (操作杆) on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.

Today we benefit from countless inventions and innovations. It’s hard to imagine driving without Garrett A. Morgan’s traffic light. It’s equally impossible to picture a world without Katherine J. Blodgett’s innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?
