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.
【小题1】Which of the following is true of Jae Kwon?

PART THREE: READING COMPREHENSION (30分)
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
A
The Wuhan to Guangzhou MU(动车组) Train route will start to operate on the 26th of this month. The train is the fastest in the world. All the construction and preparations for the route's operation are in the final stages. Our reporter Li Dong has the details.
In a trial operation, the speed of the MU Train reached 394 kilometers per hour, the highest in the world. Though the speed during normal operation may be at 350 kilometers per hour, but this newly built high speed railway may still reduce the travel time of Wuhan to Guangzhou from more than 10 to 3 hours.
The total length of Wuhan—Guangzhou high speed railway is more than 1068 kilometers. The railway connects Hubei, Hunan and Guangdong. The total investment is more than 116 billion yuan.
Protection facilities like bars and surveillance cameras are installed along the whole railway. Zhang Shuguang, director of transport bureau of the Ministry of Railway says the safety system of the train and the route is also state of the art.
"The break distance of the train is 5 kilometers. But the MU Train can respond to any emergency situations within 32 kilometers. It's very safe."
The shortened travel distance is good news for many people. However some passengers also hope the service can be upgraded.
"The dinning and entertainment service can be better. I hope I can watch TV on the train."
"The weariness during travel can be eased if I can use internet on the train. I can feel more comfortable."
Jing Libin is the MU Train driver of the Wuhan—Guangzhou high speed railway. As a MU Train engineer who witnessed China's high speed railway development. Jing Libin says: It's a way faster!
"The development of China's railway is so fast. In the beginning of the year, the speed is only 160 kilometers per hour. Soon, the speed reached 250 kilometers. And now, it's 350 kilometers! As a driver, I am very impressed."
China plans to increase the railway operation length from the current 80 thousand kilometers to 110 thousand kilometers, which includes 18 thousand kilometers of high speed passenger railways by 2012.
Within 3 years, China plans to build an "8 Hour, High Speed Transportation Circle", which means, passengers may reach nearly all the provincial capital cities in China in about 8 hours by high speed railway. With the development of the railway, China’s economy will also continue her highest development. In the near future, China will be really powerful in the world.
56. What is the best title of the passage?
A. Fastest Train in the World
C. High Speed Railway Construction
B. Trial Operation of the MU Train
D. Newly Typed Train in the World.
57. Surveillance cameras are used for________.
A. art B. speed C. safety D. research
58. How much time would be needed from Wuhan to Guangzhou if the train travelled at its top speed?
A. a little more than three hours C. more than four hours
B. less than three hours D. less than seven hours
59. What can we learn from the passage?
A. There will be no problems on the new train.
B. Passengers are completely satisfied with the new train.
C. Jing Libin is very proud of the development of China’s railway.
D. China has 110 thousand kilometers ofthe railway operation length now.
60. What can we infer according to the author?
A. Nobody expected China would have such a fast train.
B. China will build more high speed railways.
C. The service of the train is hard to be improved.
D. China’s economy would slow down if her transport couldn’t be improved.

科目：高中英语 来源：2014届安徽池州一中高三第一次月考英语卷 题型：阅读理解
Taiwan-born American director Ang Lee's win of his second directing Oscar has sparked complex feelings among Chinese audiences, who expressed their pride due to the director's Chinese roots, but couldn't help but reflect on why the Chinese mainland has failed to deliver more outstanding films to the world .
Lee, 58, on Sunday accepted the Academy Award for best director for Life of Pi, a 3D adventure-drama film. Lee had won the top directing award in 2006 for Brokeback Mountain and the best foreign language film Oscar in 2001 for Crouching Tiger, Hidden Dragon.
Lee came to Hollywood's attention after directing three Chinese-language films in the early 1990s, with an emphasis on the interactions between modernity and Chinese traditions. Some Web users called Lee "a source of pride for Chinese people," and admired him for bearing the torch of Chinese culture.
However, a large number of audience members and critics from the mainland expressed their frustrations over home-made movies: Mainland filmmakers have made numerous ambitious tries for the prestigious award but never won.
Hao Jie, a young director whose 2010 film Single Man won the Special Jury Prize in the Tokyo Filmex Festival but was never screened in the mainland for it showed complex sex lives in a village.
"Due to the censorship(审查), we are prevented from the beginning of our production, which forbids our works from mirroring realities," Hao said.
While acknowledging the system's role in undermining(削弱) excellent works, Su Mu, a well-known film critic, argued that the atmosphere in the mainland's film circle is also to blame. "Lee produces his works with his heart, but most mainland directors now only have money in mind."
Though having obtained approval for his second film from the film authority, Hao said cinemas have kept delaying the screening of his work. "This is another factor that prevents us from progressing. Cinemas won't risk showing our film, which features no stars and is considered non-mainstream," complained Hao.
1.What does the underlined phrase “the prestigious award” refer to?
A. the Best Director of Oscar
B. any of the Oscar Awards
C. the Special Jury Prize
D. the best foreign language film Oscar
2.Which of the following statements is true?
A. Ang Lee’s films are always focusing on Chinese traditions.
B. Chinese audiences are proud of their Chinese identity in the films.
C. Ang Lee has won the world’s favor only by means of his three Oscars.
D. Ang Lee is famous for his combining modernity and Chinese traditions.
3.Which of the following is NOT the factor that prevents Chinese mainland films’ progressing?
A. Strict censorship.
B. A lack of wonderful directors.
C. The bad atmosphere in the film circle.
D. Cinemas’ not risking showing low-cost films.
4.The best title for the passage is probably_____.
A. Ang Lee-Pride of Chinese Movie-makers
B. The Future of Chinese Mainland Film-making
C. Bitter-sweet Feeling over Ang Lee’s Oscar Win
D. What Can Chinese Films Do for the Oscar Awards
