Three-Dimensional （3D） movies have been becoming more and more popular in recent
题型：不详难度：来源：
"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 （眼科医师） 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 （感觉） of depth," said Dr Deborah Friedman, an ophthalmologist in New York．The images people see in three dimensions in the movies are not calibrated （校准的） 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 （竭尽全力）," 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（放映机）, 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 proj
ector, 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 （新鲜事物）．"I suspect there will be a lot of people who say it"s sort of neat, but it"s not really comfortable," he said．小题1:The text is mainly about ____．
| A．the reasons why people like 3D movies |
| B．how to improve 3D technology |
| C．the development of 3D technology in recent years |
| D．causes of headaches and nausea when people watch 3D movies |

The bored teenagers of Gaochun are impatient with the leisurely pace of hometown life．For them there is no nightlife to speak of, no bright lights, no excitement and they cannot wait to grow up and leave for the urban attractions of the big cities．But it is this laid-back lifestyle that has attracted international attention．At least, a quiet village within Gaochun county has come under the spotlight．Yaxi village, population 20,000, is about to be designated China"s first "slow city" by Cittaslow, the sustainable lifestyle movement that first surfaced in Italy 11 years ago．
At home, the residents at Yaxi are unfazed and pretty much unimpressed by the honor．To them, life has been like this for as long as they can remember．Here, growing old gracefully is natural．
Nobody living in this little county had heard of Cittaslow or the words "slow city" before this．
"The first time I heard the term was last July, when the vice-president of Cittaslow, Angelo Vassallo, visited Yaxi village," says Zuo Niansheng, the chief editor of local newspaper Gaochun Today．
"Vassallo was deeply impressed by this village"s natural and cultural resources and said it perfectly fitted the requirements for a slow city," says Zuo．"That was how Yaxi became connected with Cittaslow．
The Slow City must also be committed to protect and maintain the natural environment as well as promote a sustainable way of development ?all of which are the current strategies adopted in Gaochun．"We"ve been doing this for years," adds Zuo．
Cittaslow was founded in Tuscany, Italy in 1999．It was a spin-off from the Slow Food movement which started, also in Italy, in 1986 as a protest against the first McDonald " s opening near the Spanish Steps in Rome．The movement championed a return to healthy, nutritious home-grown, home -cooked food．
Slow Food has since expanded globally to more than 130 countries．Its mission has also broadened to include the promotion of sustainable foods and local small businesses, and the localization as opposed to globalization of food production．
Cittaslow is an expansion of the Slow Food movement, and it actively advocates a lifestyle that is sustainable, that will improve quality of life, and will preserve cultural and culinary （烹饪的）heritage．
小题1:According the passage, Cittaslow is a（n） ____．
| A．organization | B．person | C．lifestyle | D．honor |
| A．very excited． | B．very shocked |
| C．indifferent | D．very happy |
| A．it is full of excitement and activities of nightlife |
| B．the residents at Yaxi enjoy a leisure life |
| C．it is very rich and has a lot of attractions |
| D．foreign people like small towns than big cities. |
| A．young people at Yaxi enjoy their life very much |
| B．China is more and more popular with foreign people |
| C．the first McDonald’s in Europe was opened in Spain |
| D．the lifestyle of “slow city” will be good to environment and people |
But paying online is a tricky business for consumers who are too young to own credit cards．Most have to use a parent’s card．They want a facility that allows them to spend money.
That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are coming out rapidly on both sides of the Atlantic．If successful, these products can stimulate online sales.
In general, teenagers spend huge amounts: $153bn (billion) in the US last year and ￡20bn annually in the UK．Most teenagers have access to the Internet at home or at school－88 percent in
the US, 69 percent in the UK．According to the Jupiter Research, one in eight of those with Internet access has bought something online－mainly CDs and books.In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children．Pressing parents to spend online is less productive than pressing on the high street．They are more likely to ask “Why?” if you ask to spend some money online.
One way to help teenagers change notes and coins into cybercast is through prepaid cards such as Internet Cash in the US and Smart cards in the UK．Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as￡20 or $50 with a concealed 14-digit number that can be used to load the cash into an online account.
小题1:What does the word “They” in paragraph 1 refer to?
| A．Sellers. | B．Buyers. | C．Teenagers. | D．Parents. |
| A．More than half of the teenagers in the US and the UK have Internet access． |
| B．Teenagers pay for goods online with their own credit cards. |
| C．Most teenagers in the US and the UK have bought something online. |
| D．Teenagers found it easier to persuade parents to buy online than in a shop. |
| A．a new machine | B．special coins and notes |
| C．prepaid cards | D．pay-as-you-go mobile phones |
| A．Online shopping traps. | B．Internet users in the US and the UK. |
| C．New credit cards for parents. | D．The arrival of cyber pocket money. |
Important developments in the last century are the breading down of the class structures left over from the Industrial Revolution stage, bringing with it the empowerment of the “common man ”: the working day is set by law to only 8 hours a day, everyone has the vote, the media has less obvious government control, people have landed on the moon, sent spacecrafts to Mars and so on. Families have also shrunk drastically（强烈地）; the nuclear family came about, and especially in the last half of the 20th century, one-parent families are becoming more common. This shrinking in the size of the family shows the increased independence of people—once upon a time people had to live in large groups to survive.
As humans have “become the gods”, they have realized their individuality and independence and taken their control of the world to an extreme. In many countries the land is almost completely used in the land is almost completely used in the production of food and as living space and they live in small cities which are entirely human constructed, made from materials which are also entirely human constructed(concrete, bricks) with hardly any remains of nature. Weeds are poisoned because they are messy; even parks have trees grown in tidy lines; grass is mowed to keep it short and so on. I think the massive drug “problem” troubling people is a result of too much of this influence, humans needing to escape the stark world they have created by entering fantasy worlds.
Over the last 100 years, the 20th century consciousness has spread throughout the world; most of Asia has been thoroughly “Westernized”, and most of the Third World is being overrun by western ways of doing things and living.
小题1:What’s the author most concerned about?
| A．The influence of pollution. |
| B．Strong effects of development. |
| C．Changed positions of humans as gods. |
| D．The process of the Industrial Revolution. |
| A．Objective. | B．Tolerant. | C．Vague. | D．Negative. |
| A．Unfair. | B．Illegal. | C．Dull. | D．Violent. |
| A．Men’s individuality is over controlled. |
| B．People have damaged nature too much. |
| C．Men’s independence is partially limited. |
| D．People show concern for nuclear families. |
When tension arises in a relationship between two people, a frequent way of dealing with this is to send messages through a third person. Family doctors refer to the process as ‘triangulation”. Following a quarrel, a mother may say to her son, “Tell your father to pass the salt”, which may be answered by, “Tell your mother to get her own salt.” In many long cases of triangulation, the middleman becomes severely disturbed.
Two years ago, Ruth and Ralph Gordon brought their 17-year-old daughter for treatment. Lucille was not doing well in school, using drugs heavily. When I began to work with her, she was uncommunicative and aggressive. After some time, however, she opened up and told me her parents rarely talked to each other, but both used her as a middleman. Mrs. Gordon was sexually unsatisfied and suggested to Lucille that she ask her father to go for marriage advice. Mr. Gordon told Lucille that he was seeing another woman, and he urged Lucille to speak to her mother about improving her behaviour. Caught in this confusing situation, Lucille became more and more troubled. It wasn’t until she refused to play middleman that she began to improve. When either parent began to send a message through her, she learned to say, “Tell him/her yourself!”
You’ll find that when family members learn to dial each other directly, there’s rarely a busy signal or wrong number. With direct dialing, a sense of freshness is created.
小题1:The underlined words “foul things up” in the 1st paragraph means ________.
| A．create things | B．improve things | C．remove things | D．ruin things |
| A．the process of sending messages through a 3rd person |
| B．the middleman who becomes severely disturbed |
| C．the tension in a relationship between 2 people |
| D．the argument between a mother and a father |
| A．family members should learn to get their messages across directly |
| B．parents should send their children taking drugs for treatment |
| C．children can hardly get used to their parents’ troubles |
| D．children should refuse the requests of their parents |
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.
小题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 festivals | D．teach his daughter how to sing |
| A．hope for Daae and Christine | B．appreciation of Daae and Christine |
| C．sympathy for Daae and Christine | D．love for Daae and Christine |
| A．always sleepy | B．so homesick that he fell ill |
| C．too busy teaching his daughter | D．willing to be locked up with his daughter |
| 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 |
