     Music is an international language. The songs that are sung or played by instruments are beautiful to all people everywhere.
     Popular music in America is what every student likes. Students carry small radios with earphones and
listen to music before class, after class and at lunch. Students with cars buy large speakers (扬声器) and
play the music loudly as they drive on the street.
     Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about
sports, the weather, politics, and activities of the American people. But most of the radio broadcast is
music.
     Pop or popular music singers make much money. They make a CD or tape which radio stations use
in every state. Once the popular singer is heard throughout the country, young people buy his or her tapes. Some of the money from these tapes comes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.
     Besides pop music, there are two other kinds of music that is important to Americans. One is called
folk music. It tells stories about the common life of Americans. The other is called western or country
music. This was started by cowboys who would sing at night to the cows they were watching. Today,
any music about country life and the love between a country boy and his girl is called western or country
music.
1. According to the passage, most of the car radio broadcast is ________.
A. sports        
B. the weather      
C. politics

　　Motorola set out a special training program for children last week with the aim of developing children’s business skills and preparing them for a future as entrepreneurs．

　　Eighty-seven children aged between 12 and 16 from Beijing and Tianjin attended the oneweek training program called “Youth Discovery” directed by Motorola University’s(MU)instructors and marketing specialists．The children learned about dealing with a practical problem－marketing and worked out a marketing plan by themselves．Last week 26 children of Motorola employees in Tianjin completed their training in the MU－Tianjin Learning Center．

　　Through the training program, children learnt how to get information through different kinds of sources(源), determine end－user needs, make up messages of value to customers, and communicate using various means and equipment．

　　Educators acted only as team “directors”, directing children to discover their own answers．The children gave their solutions(解决办法)to Motorola’s management and their parents on the last day of the program．

　　The children, most of whom were primary and middle school students, presented themselves freely．

　　The students said that they preferred the open and practical way of learning．

　　“Youth Discovery”, started by Motorola’s former president Robert Galvin, designed and carried out by Motorola University, aimed to bring the talents(才能)of young people into full play and encouraged them to discover how their skills can contribute to a team to help it reach an aim．

       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（装置）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.

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.

       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．could be extremely thin.

       D．has passed the final test.

     People often have the impression that Chinese characters are extremely difficult to learn. In fact, if
you were to try to learn how to write Chinese characters, you would find that they are not nearly as
difficult as you may have imagined. And they certainly qualify as forming one of the most attractive,
beautiful, logical(合乎逻辑的), and scientifically constructed(构造) writing systems in the world. Each
stroke(笔画)has its own special significance. If you are familiar with the rules of Chinese characters, you
will find it very easy to remember even the most complicated looking character, and never miss a stroke.
     The earliest known examples of Chinese written characters in their developed form are carved into
tortoise shells and ox bones. The majority of these characters are pictographs. Archaeologists of various
countries have learned that most early writing systems went through a pictographic stage, as did the
Egyptian hieroglyphics. Most writing systems, however, eventually developed a phonetic(表示语音的)
alphabet to represent the sounds of spoken language rather than visual images observed in the physical
world.
     One notable feature of Chinese characters is the "radical." "Radical" in English means "root". For
example, the characters yu "language," shuo "talk," i "discuss," "opinion," and lun "discuss" all share the
yen radical, which means "language," and gives the reader a clue to the meaning of the character as a
whole. The characters hsiu "rotten," shan "cedar," " t'ao "peach," and lin "forest," all contain the mu
"wood" or "tree" radical, indicating one of their shared key characteristics. If you know the radical of a
character, you can usually get a general idea of the meaning of the character it is a part of. Although there
is a theoretical total of almost 50,000 written Chinese characters, only about 5,000 of these are frequently used; and the total number of radicals is only 214. So learning to read and write Chinese is not nearly so
formidable a task as it may at first seem.
1. According to the author, Chinese characters are _____
A. extremely difficult to learn  
B. as difficult as you may have imagined
C. difficult to remember   
D. scientifically constructed
2. Which of the following statements is TRUE according to the passage?
A. All the Chinese characters are pictographs.
B. Some strokes are more important than others.
C. There are rules in forming the Chinese characters.
D. Some writing systems eventually developed a phonetic alphabet.
3. The passage is mainly about _____.
A. the Chinese writing system
B. the strokes of the Chinese characters
C. pictographs
D. the radical of the Chinese characters
