    School violence is in the headlines again after recent shootings at schools in Pennsylvania, Wisconsin, and Colorado. After hearing the news, it’s natural for students — no matter how old they are or where they go to school — to worry about whether this type of incident may someday happen to them.
    So how safe are schools? It’s actually safer to be in a school than in a car. Twice as many 15-to-19-year-olds die in car accidents than in shootings (and that’s all shootings, not just the ones that happen in schools). According to the Centers for Disease Control and Prevention, less than 1% of all homicides (杀人罪) among school-age children happen on school grounds or on the way to and from school. So the vast majority of students will never experience violence at school.
    However, some schools have re-evaluated their safety needs in response to the concerns of families and communities. Some now require that guests check in at the office or have more guards on duty. Some schools have fixed metal detectors. Another thing that helps make schools safer is greater awareness of problems like bullying and discrimination. Many schools have practiced programs to fight these problems and to help teachers and administrators know more about protecting students from this type of violence.
    The cause of school violence isn’t easy to understand. There is no single reason why students become violent. Some are just copying behavior they’ve seen at home, in the streets, or in video games, movies, or television. There’s one thing experts do agree on, though: Having access to guns or other weapons makes it easier for some people to lash out against the things or people they don’t like.
    小题1:Which of the following statements can prove that schools are safe?
    A．About 99% of 15- to-19-year-olds are safe at school.
    B．Fewer students have died in car accidents than in shootings.
    C．Students shot to death at school are half of all students.
    D．Fatal shootings of students are less than 1% of all homicides.
    小题2: After schools have re-evaluated their safety needs, ________.
    A．families will be more concerned about schools
    B．communities will be responsible for schools
    C．teachers will pay more attention to shootings
    D．administrators will arrange to have more guards on duty
    小题3:From the last paragraph we can conclude that ______.
    A．experts have found no reason for school violence
    B．students with weapons are easily upset about things
    C．school violence could be copied from violence in society
    D．no single reason makes students violent
    小题4:We could probably see this passage in ______.
    A．an analysis reportB．a realistic novel
    C．a case investigationD．a news journal

    小题1:D

    In recent years, especially during the l960s, there was much discussion about “the brain drain (排干, 流失),” which dealt with the problem of students and learned people who left their own countries for other countries that offered better chances for study, research, and employment．For example, according to a report from U．N., between 1962 and l966 more than 50 percent of all engineering graduates of Iran and 14 percent of Iranian scientists left their country for work abroad．Over 30 percent of Chilean engineers and 15 percent of Turkish physicians also went to work in other countries．Probably the greatest brain drain occurred among young scientists who had gone abroad to study．Many of them had planned to return to their countries to teach but chose to remain in more industrialized nations where they were able to continue their work and their research in fields in which there were no job possibilities at home．The countries that attracted most of these scientists were the United States, Great Britain, Germany, France, Canada, and Australia.
    　　Recent studies show that the brain drain to the United States may be decreasing．Many foreign scientists are going home again, and in some cases American scientists are leaving the United States for employment in other countries．The main reasons are that good jobs are becoming fewer here, money for national research has been sharply cut, and university fellowships reduced too．However, in the field of medicine the drain to the United States still goes on．Today more than one of every five American doctors is foreign - born, and several thousand foreign doctors immigrate to the United States each year．Over eighty countries have asked the State Department to send students who are skilled in important fields such as medicine back home when their study programs are over.
    小题1:Which of the following is not the reason for “the brain drain”?
    A．Good housing.　　B．Better research condition.
    C．Good job possibility　　D．Better chances of study..
    小题2:The brain drain to the United States may be decreasing mainly because __________.
    A．many foreign scientists are ordered to return to their motherlands
    B．they don’t need any foreign scientists now
    C．there are fewer and fewer good jobs in the USA
    D．the universities refuse to provide money for the foreign scientists
    小题3:How many American doctors are foreign - born?
    A．About half of them.　 　 B More than 20 percent　
    C．Several thousand.　　    D．About 15 percent.
    小题4:Which is the best title for this passage?
    A．How to seek a job in the USA.　　  B．Doctors’ immigration to the USA.
    C．A strange case.                  D．The brain drain.

    No one would be willing to pay one-third of the price for the packaging or wrapping of what he or she purchases. But over-packaging has become a disease that leads to an __50__ waste of resources and __51__ environmental pollution.
    The wasted packaging materials are __52__ to be worth about 280 billion yuan annually. And such packages and wrappings thrown away by customers __53__ up half of the volume of solid waste in cities. __54__, it is high time that regulations were __55__ to stop enterprises from spending too much on unnecessary packaging and wrapping.
    To produce paper packaging or wrapping, many more trees have to be cut down. Over-packaging also limits the interest of consumers when they have to spend quite a high percentage on something that they will have to throw into the dustbin. The simple truth is that the more a producer spends on packaging, the __56__ the products it sells will be.
    Product packaging and wrapping used to be very simple 30 years ago. "Shabby" was the word many had used to __57__ the way Chinese products were packaged. And shabby packaging was blamed for making Chinese products __58__ in the international market.
    It is __59__ to pay enough attention to packaging or wrapping products in such a manner that they can be __60__ to customers' eyes. But that does not definitely justify that packaging should even outshine what is inside.
    In the Chinese proverb, “maidu huanzhu,” the buyer returns the pearl and just keeps the case because the __61__ is too fancy and luxurious. It not only laughs at the poor __62__ of the buyer, but also criticizes the unnecessary __63__ the seller has made in making the case. Another message from the proverb is that over-packaging helps cultivate an __64__ consuming attitude - to buy fancy-looking stuff but not what they really need.

    Modern zoos are different from those built fifty years ago. Those zoos were places where people could go to see animals from many parts of the world. The animals lived in cages with iron bars. Although the zoo keepers took good care of them, many of the animals did not feel comfortable, and they often felt ill.

    The private automobile（私家车）has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.

Mothers of victims（受害者）of such accidents have formed an organization called MADD（Mothers Against Drunk Driving. These women want to prevent further tragedies（悲剧）. They have worked to encourage the government to limit the youngest drinking age, Students have formed a similar organization, SADD（Students Against Drunk Driving）and are spreading the same message among their friends.

    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，并在答题卡上将该项涂黑。
    B
    Most parents love the Internet and want their kids to use it. But a new survey in America finds almost as many also fear the online world—especially social networking sites such as My Space—and worry their kids will get in trouble with people they meet.
    “The parents see the web’s incredible potential(可能性), and they know their kids have to be there.” says James Steyer, CEO of Common Sense Media, which released results from a survey that looked into parental attitudes toward the Internet. “It is also what they are scared of most.”
    The study was conducted online May 5-10 by Insight Research Group. It says 80% of parents are concerned about kids meeting bad people online. That’s because young people who largely have grown up with the Net think of it as a social outlet(出口), say the researchers. To young people, the benefits of giving out some personal information to reach out to friends outweigh the risks. And the study shows they are so comfortable with the medium that 78% have a personal website or blog.
    Parents also recognize the importance of the Internet. The survey shows 91% think the Net helps their children explore their passions, and 77% think the Internet is one of the most valuable education tools teens have. But 88% think it’s important to know what their kids are doing online.
    Findings suggest both parents and teens need more education about using online media, Steyer says.
    Internet safety has become an increasing concern for parents in America. Organizations like the Non-profit Common Sense have been trying to reach and help parents pay attention to the problem.
    小题1: In the second paragraph, the underlined word “It” refers to_____.
    A．Common Sense MediaB．the result of the survey
    C．the web’s incredible potentialD．the website called My Space
    小题2:Why do young people give out their personal information?
    A．They think it has more advantages than disadvantages.
    B．They want to make themselves famous by doing that.
    C．They want to have a personal website each.
    D．They want to get some information from others.
    小题3: Most parents think it is important to know_____.
    A．where their children give out the informationB．what kind of websites they have
    C．how often they go onlineD．what their children are doing online
    小题4:From the passage we can infer that_____.
    A．children are too young to know how to use the Internet
    B．parents must teach their children how to use the Internet
    C．parents also need to learn more about using the Internet
    D．the Internet is the most valuable tool for children to learn

    Children at a school in Italy have today begun an experiment to replace all their books with personal computers. The pupils involved will each be given a special laptop that contains their entire courses.
    Until today, the Don Milani di Rivoli elementary school in central Turin was like any other. Children turned up, got out their books and pens and began the process of learning. But now, in what's being described as a unique experiment, 60 fifth-grade pupils and a number of third-graders, will start using computers only.
    The mini-laptops, which run Windows software, all have a full curriculum programmed into them. The pupils will use the computers to do all their reading and writing. Security systems within the laptops mean the children's access to the Internet is strictly controlled. The machines weigh less than a kilogram, can be dropped from a height of 1.5 metres and are waterproof.
    Instead of spending 700 dollars a year on books, the laptops, built by the Italian company Olidata, cost less than 400 dollars. One of the teachers involved in the scheme says that, for the first time, schools will be able to verify in a scientific way how a computer alone can improve the learning process. The experiment, which has the backing of parents, is due to last a year.
    In other countries, such a programme is also being carried out. Venezuela is ordering one million low cost laptops for its school children. The machines will be based on the Intel Classmate laptop that has been designed for school children. Many see the deal as a blow for the One Laptop Per Child organization that has also been introducing its child- friendly machine to developing nations.
    小题1: Which of the following is TRUE about the mini-laptop?
    A．It is heavy for pupils to carry. B．It can't be damaged by water.
    C．It is one and a half meters high.D．It is easily broken or damaged.
    小题2: The pupils use the laptop to ____ in class.
    A．learn their lessons as an aid
    B．have a course named computer studies
    C．surf the Internet mainly to find information
    D．do what they used to do with books and pens
    小题3: How much money can a pupil save by using the mini-laptop to replace all the books in a year?
    A．Less than 400 dollars.B．More than 400 dollars.
    C．More than 300 dollars. D．Less than 300 dollars.
    小题4:Which of the following about the experiment is TRUE?
    A．It has been carried out for over one year.
    B．It has already turned out to be a success.
    C．The pupils' parents are against it in fact.
    D．The pupils' parents are supportive to it.

    Modern inventions have speeded up people’s loves amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boats (吹嘘) of saving precious seconds in handling tasks.
    All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so.  We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind on another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientist; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.
    However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.
    There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestor faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence.
    小题1: The new products become more and more time-saving because        .
    A．our love of speed seems never-endingB．time is limited.
    C．the prices are increasingly high.D．the manufactures boast a lot.
    小题2:What does “the days” in Paragraph 3 refer to ?
    A．Imaginary lifeB．Simple life in the past.
    C．Times of inventionsD．Time for constant activity.
    小题3: What is the author’s attitude towards the modern technology?
    A．CriticalB．Objective.C．Optimistic.D．Negative.
    小题4: What does the passage mainly discuss?
    A．The present and past times.B．Machinery and human beings.
    C．Imaginations and inventions.D．Modern technology and its influence.
