Three-Dimensional （3D） movies have been becoming more and more popular in recent years．It seems 3D TV sets may be going into family households in the near future．While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say．

"There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist （眼科醫(yī)師） in Chicago．He said in a 3D movie, these people face a completely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters．
In normal vision, each eye sees things at a slightly different angle．"When that gets processed in the brain, that creates the perception （感覺） of depth," said Dr Deborah Friedman, an ophthalmologist in New York．The images people see in three dimensions in the movies are not calibrated （校準(zhǔn)的） in the same way that their eyes and brain are．"If your eyes are a little off to begin with, then it's really throwing a whole degree of effort that your brain now needs
to exert （竭盡全力）," he said．                    
Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all．He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images．
Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off．
Heineman said older 3D technology used two film projectors（放映機(jī)）, one that projected a left-eye image and one that projected a right-eye image．Three-D glasses would allow viewers to see a different image in each eye．
"People often complained of headaches and it was really because the projectors weren’t lined up," Heineman said．
Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems．
"By going to a single digital projector, those problems were solved," he said．Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty （新鮮事物）．"I suspect there will be a lot of people who say it's sort of neat, but it's not really comfortable," he said．

If you live in the United States, you can’t have a full-time job until you are 16 years old. At 14 or 15, you work part-time after school or on weekends, and during summer vacation you can work 40 hours each week. Does all that mean that if you are younger than 14, you can’t make your own money? Of course not! Kids from 10-13 years of age can make money by doing lots of things.
Valerie, 11, told us that she made money by cleaning up other people’s yards. Lena, 13, makes money by knitting(織) dog sweaters and selling them to her neighbors. Reisa said she had started taking art classes and showing her works to people. People ask her to draw pictures for them and they pay her for them. Jasmine. 13, writes articles for different magazines!
Kids can learn lots of things from making money. By working to make your own money, you are learning the skills you will need in life. These skills can include things like how to get along with others, how to use technology and how to use your time wisely. Some people think that asking for money is a lot easier than making it; however, if you can make your own money, you don’t have to depend on anyone else.

Americans think that travel is good for you. Some even think it can help to solve one of the coun­try ’ s worst problems ~: crime (犯罪）.
Crime worries a lot of people. Every year, the number of crimes is up and up. And many criminals (罪犯）are young. They often come from sad homes, with only one parent or no parents at all.

There was once, in a little market-town not far from Upsala (瑞典一城市), a peasant who lived there with his family, digging the earth during the week and singing in the choir on Sundays. This peasant had a little daughter to whom he taught the musical alphabet before she knew how to read. Daae was a great musician, perhaps without knowing it. Not a violinist in Scandinavia played as he did. His reputation was widespread and he was always invited to set the couples dancing at weddings and other festivals. His wife died when Christine was entering upon her sixth year. Then the father, who cared only for his daughter and his music, sold his land and went to Upsala in search of fame and fortune. He found nothing but poverty.
He returned to the country, wandering from fair to fair, playing his Scandinavian music pieces, while his child, who never left his side, listened to him in delight or sang to his playing. One day, at Ljimby Fair, Professor Valerius heard them and took them to Gothenburg. He insisted that the father was the first violinist in the world and that the daughter had the making of a great artist. Her education and instruction were provided for. She made rapid progress and charmed everybody with her prettiness, her grace of manner and her real eagerness to please.
When Valerius and his wife went to settle in France, they took Daae and Christine with them. "Mamma" Valerius treated Christine as her daughter. As for Daae, he became ill with homesickness. He never went out of doors in Paris, but lived in a sort of dream which he kept up with his violin. For hours at a time, he remained locked up in his bedroom with his daughter, playing and singing, very, very softly.
Daae seemed not to recover his strength until the summer, when the whole family went to stay at Perros-Guirec, in a far-away corner of Brittany, where the sea was of the same color as in his own country. Often he would play his saddest tunes on the beach and pretend that the sea stopped its roaring to listen to them. And then he persuaded Mamma Valerius to allow him to leave for a while. At the time of the "pardons," the village festivals and dances, he went off with his violin, as in the old days, and was allowed to take his daughter with him for a week. They gave the smallest villages music to last them for a year and slept at night in a barn, refusing a bed at the inn, lying close together on the straw, as when they were so poor in Sweden. At the same time, they were very neatly dressed, refused the halfpence offered to them; and the people around could not understand the behaviour of this country violinist, who walked heavily on the roads with that pretty child who sang like an angel from Heaven. They followed them from village to village.
小題1: When he was in the countryside, Daae did NOT __________.
A．work on his land B．sing in the choir on Sundays
C．make a fortune at weddings and festivalsD．teach his daughter how to sing
小題2:The 3rd sentence “He insisted …” in the 2nd paragraph showed Professor Valerius’ ______.
A．hope for Daae and Christine B．a(chǎn)ppreciation of Daae and Christine
C．sympathy for Daae and ChristineD．love for Daae and Christine
小題3: While Daae was in Paris, he never went out of doors because he was ________.
A．a(chǎn)lways sleepy B．so homesick that he fell ill
C．too busy teaching his daughterD．willing to be locked up with his daughter
小題4: What made people curious about the father and daughter was that _______.
A．the father made very good music
B．the daughter sang like an angel from Heaven
C．the father walked strangely with his daughter
D．they appeared to be badly off but refused money offered
