    In meditation(冥想)，people sit quietly and focus their attention on their breath .As they breathe in and out ,they attend to their feelings .As thoughts go through their minds. They let them go. Breathe .Let go .Breathe .Let go .
    According to a recent study at the Insight Meditation Society in Barre,Massachusetts. Three months of training in this kind of meditation causes a market change in how the brain allocates(分配) attention. It appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things and events in the outside world. Expert mediators are better than other people at catching such fast-changing stimuli( 刺激),like facial expressions.
    The study provides evidence for changes in the workings of the brain with mental training. People can learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-being.
    In an experiment, 17 volunteers with no meditation experience in the experimental group spent three months meditating 10 to 12 hours a day .A control group also with no meditation experience meditated for 20 minutes a day over the same period .Both groups were then given the tests with two numbers in a group of letters. As both group looked for the numbers , their brain activity was recorded.
    Everyone could catch the first number .But the brain recordings showed that the less experienced mediators tended to grasp the first number and hang onto it, so they missed the second number .Those with more experience gave less attention to the first number .as if letting it go ,which led to an increased ability to grasp the second number ,This shows that attention can change with practice.
    Just ask Daniel Levision , who meditated for three months as part of the study .”I am a much better listener,” he said . “ I do not get lost in my own personal reaction to what people are saying.”

    A．were more likely to catch both of the members
    B．were used to memorizing numbers in groups
    C．usually ignored the first number observed
    D．paid more attention to numbers than to letters

    A．meditation improves one’s health
    B．brain activity can be recorded
    C．human attention can be trained
    D．mediators have a good sense of hearing

    Some kids start to drink alcohol (酒精) at a young age. They think it is part of becoming an adult. They also think drinking is not that bad because so many people do it. They feel it is not as bad as taking drugs (毒品). It is easy for kids to get liquor （酒精饮料）by using fake identification (伪造证件).

    Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years ago, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
    A new study from Switzerland, sheds light on where ice sheets melted during the ice age. It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern regions.
    This surprised the researchers from the University of Bern. Scientists have long assumed that most of the ice that melted was in the Northern hemisphere(半球) during the 30,000-year long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea the ice can easily just slip into the ocean instead of building up.
    The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the Northern hemisphere that ice melted, there would have been a bigger impact(影响) on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too. The only reasonable conclusion, the scientists could make, was that ice melted equally in the North and the South.
    It is still a mystery as to what caused the temperature changes that caused the ice to melt.
    小题1:The North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. So scientists thought that ________.
    A．most of the ice melted in the Northern hemisphere
    B．most of the ice melted in the Southern hemisphere
    C．The North Pole is colder than South Pole
    D．The South Pole is colder than North Pole
    小题2:We can infer from the passage ________.
    A．the ice can easily just slip into the ocean
    B．volcanoes caused the ice to melt
    C．melting just in the Northern hemisphere would have been impossible
    D．researchers often use the computer models help their research work.
    小题3:The scientists are not sure ________.
    A．how long the ice age lasted
    B．where ice sheets melted during the ice age
    C．what caused the temperature changes
    D．what the earth is made up of
    小题4:Which of the following is the best title for the passage?
    A．A computer model
    B．Studies show ice melted equally in the North and the South during the ice age
    C．Most of the ice melted in the Northern hemisphere during the 30,000-year long ice age.
    D．A survey result

    Taiwan police cannot decide whether to treat it as an extremely eleven act of stealing or an even cleverer cheat . Either way , it could be the perfect crime (犯罪), because the criminals are birds—horning pigeons !
    The crime begins with a telephone message to the owner of a stolen car : if you want the car back, pay up then, the car owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside . Carrying the money in a tiny bag , the pigeon flies off .
    There have been at least four such pigeon pick-ups in Changwa. What at first seemed like the work of a clever stay-at-home car thief, however , may in face be the work of an even lazier and more inventive criminal mind—one that avoid (避免)not only colleting money but going out to steal the car in the first place . Police officer Chen says that the criminal probably has pulled a double trick: he gets money for things he cannot possibly return . Instead of stealing cars , he lets someone else do it and then waits for the car-owner to place an ad (启事) in the newspaper asking for help .
    The theory is supported by the fact that , so far , none of the stolen cars have been returned . Also, the amount of money demanded-under 3,000 Taiwanese dollars –seems too little for a car worth many times more .
    Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the criminal . “We have more important things to do, ” he said .
    1．After the car owner received a phone call. He          
    A．went to a certain pigeon and put some money in the bag it carried
    B．gave the money to the thief and had his car back in a park
    C．sent some money to the thief by mail
    D．told the press about it
    2．The “lazier and more inventive” criminal refers to          .
    A．the car thief who stays at home     
    B．one of those who put the ads in the paper
    C．one of the policemen in Changwa  
    D．the owner of the pigeons
    3．The writer mentions the fact that “none of the stolen cars have been returned” to show       .
    A．how easily people get fooled by criminals
    B．what Chen thinks might be correct
    C．the thief is extremely clever
    D．the money paid is too little
    4．The underlined word “they” in the last paragraph refers to          .
    A．criminals            B．pigeons
    C．the stolen cars    D．demands for money
    5．We may infer from the text that the criminal knows how to reach the car owners because     .
    A．he reads the ads in the newspaper  
    B．he lives in the same neighborhood
    C．he has seen the car owners in the park 
    D．he has trained the pigeons to follow them

    阅读理解: 阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
    Young adult filmmakers all hope to show their works in international festivals like Sundance and Toronto. But what about really young filmmakers who aren’t in film school yet and aren’t, strictly speaking, even adults?
    They are at the heart of Wingspan Arts Kids Films Festival, tomorrow, in a setting any director might envy: Lincoln Center. Complete with “red carpet” interviews and various awards, the festival has much in common with events for more experienced moviemakers, except for the age of the participants: about 8 to 18.
    “What’s really exciting is that it’s film for kids by kids,” said Cori Gardner, managing director of Wingspan Arts, a nonprofit organization offering youth arts programs in the New York area. This year the festival will include films not only from Wingspan but also from other city organizations and one from a middle school in Arlington, Virginia. “We want to make this a national event,” Ms. Gardner added.
    The nine shorts to be shown range from a Claymation biography of B.B. King to a science fiction adventure set in the year 3005. “A lot of the material is really mature,” Ms. Gardner said, talking about films by the New York City branch of Global Action Project, a media arts and leadership-training group. “The Choice is about the history of a family and Master Anti-Smoker is about the dangers of secondhand smoke.” Dream of the Invisibles describes young immigrants’ feelings of both belonging and not belonging in their adopted country.
    The festival will end with an open reception at which other films will be shown. These include a music video and full-length film whose title is Pressures.
    1. Wingspan Arts Kids Film Festival ____.
    A. is organized by a middle school
    B. is as famous as the Toronto Festival
    C. shows films made by children
    D. offers awards to film school students

    D. It’s a national organization for young people.
    3. The underlined word “shorts” in Paragraph 4 refers to _____.
    A. short trousers  B. short kids   C. short films   D. short stories
    4. Movies to shown in the festival ____.
    A. cover different subjects.
    B. focus on kids’ life
    C. are produced by Global Action Project
    D. are directed by Ms. Gardner

    Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can’t be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone in bed, taking no notice of the worms. But is it interfering(干涉) with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.
    Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance(机械维修，保养) as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results will be. And at what point should you stop to treat the old body? Is it morally right to try to push off death by seeking the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You can’t ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there’s life, there’s hope.
    When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun.
    1. What does the passage mainly tell us?
    A. The values are different between the old and the young.  B. The moral problems raised by old people.
    C. The personal freedom for the old.                    D. Old people’s viewpoint on life.
    2. We can know from the first paragraph that________.
    A. Very old people would like to live alone to have more personal freedom.
    B. Very old people are able to keep their room clean.
    C. Very old people like to live with their children.
    D. Social services have nothing to do with very old people.
    3. According to the author, which of the following is right?
    A. The older a person, the more care he needs.  B. Too much emphasis has been put on old people’s values.
    C. The human body can’t be compared to a car.  D. It is easy to provide spare parts for old people.
    4.The underlined word “it” in the last paragraph refers to “________”.
    A. their money or their health          B. the conclusion you come to
    C. your talk to the old people         D. whether age is happy or unpleasant

    Organic food, once considered something that only health fanatics desired, is now a regular feature at most supermarkets. And that has created a bit of a dilemma. On the one hand, you have a conventionally grown apple. On the other, you have one that’s organic. Both apples are firm, shiny and red. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.
    Conventionally grown food generally costs less, but is organic food a better choice? The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale. Supporters of organic foods ― a term whose meaning varies greatly ―are frequently telling the world that such products are safer and more nutritious than others.
    The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development. However, much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs.
    Almost daily, the public is surrounded by claims for “no-aging” diets, new vitamins and other wonder foods. There are numerous unsubstantiated(没证实的) reports that natural vitamins are superior to man-made ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than those treated with insect spray and the like.
    Although most of these claims are not supported by scientific evidence, large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction. As a result, claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people’s opinion.
    One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the conventional food supply and buy only expensive organic foods instead.
    小题1:According to Paragraph 2, which of the following statements about organic food is true?
    A．It hasn’t been used until recent years.
    B．It has no agreed definition.
    C．It is popular among producers.
    D．It is accepted by most nutritionists.
    小题2:In Paragraph 4, treated grains are examples of ________.
    A．healthier foodB．organic food
    C．conventionally grown foodD．expensive food
    小题3:It can be inferred from the passage that ________.
    A．most doctors believe organic foods prevent disease or provide other benefits to health
    B．organic foods are actually less nutritious than conventionally grown foods
    C．people cannot separate fact from fiction because of the TV advertisements
    D．organic foods cost more but are not necessarily better than conventionally grown foods
    小题4:According to the passage, many consumers are attracted by organic foods because they _____.
    A．want to try something new
    B．have carefully researched the products
    C．value food safety and nutrition
    D．expect to save some money
    小题5:What is the author’s attitude towards the claims of organic foods?
    A．Doubtful.B．Enthusiastic.
    C．Supportive.D．Uninterested.
