     "Mum, what does it mean when someone tells you that they have a skeleton (骨骼) in the closet (衣橱)?"
Jessica asked. "A skeleton in the closet?" her mother paused thoughtfully. "Well, it's something that you would
rather not have anyone else know about. For example, if in the past, someone in Dad's family had been arrested
for stealing a horse, it would be a skeleton in his family's closet. He really wouldn't want any neighbor to know
about it."
     "Why pick on my family?" Jessica's father said with anger. "Your family history isn't so good, you know.
Wasn't your great-great-grandfather a prisoner who was transported to Australia for his crimes?" "Yes, but
people these days say that you are not a real Australian unless your ancestors arrived as prisoners." "Gosh, sorry
I asked. I think I understand now," Jessica cut iin before things grew worse.
     After dinner, the house was very quiet. Jessica's parents were still quite angry with each other. Her mother
was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending
to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica's closet.
Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark depths and a
bundle of white bones fell to the floor. Jessica's mother sank in a faint (晕倒), waking only when Jessica put a
cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.
     "What happened? Where am I?" she asked. "You just destroyed the school's skeleton, Mum," explained
Jessica. "I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as
I mentioned skeletons and closets, it caused a problem between you and Dad." Jessica looked in amazement as
her parents began to laugh madly. "They're both crazy," she thought.
1. According to Jessica's mother, "a skeleton in the close" means _____.
A. a family honor
B. a family secret
C. a family story
D. a family treasure
2. What can we learn about some Australians' ancestors form Paragraph 2?
A. They were brought to Australia as prisoners.
B. They were the earliest people living in Australia.
C. They were involved in some crimes in Australia.
D. They were not regarded as criminals in their days.
3. Why did Jessica bring a skeleton home?
 A. She was curious about it.
B. She planned to keep it for fun.
C. She needed it for her school task.
D. She intended to scare her parents.
4. Jessica's parents laughed madly at the end of the story probably because _____.
A. they were crazy
B. they were over excited
C. they realized their misunderstanding
D. they both thought they had won the quarrel

　　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
