Broken rubber bands and flat tires requiring replacement could soon be a thing of the past．
French researchers have developed a new kind of rubber that can repair itself when broken．The new rubber is made from widely available materials including vegetable oil and a common industrial chemical．All the materials are considered safe to the environment and can be easily reused．
The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch．When cut, the rubber can be made new again, simply by pressing the two broken ends back together．
The product can be repaired at room temperature, around twenty degrees Centigrade；other self-healing materials require higher temperatures for repair．
Traditionally, rubber substances are made from huge molecules（分子）connected by strong chemical links, or bonds．The new rubber is made of smaller molecules．The molecules are linked together using hydrogen bonds．When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks（超分子網(wǎng)）．When the rubber is cut, the molecules attempt to connect with whatever molecule is near them．When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new．
However, time is an important element in the process．If the broken ends are not brought together quickly, a repair is not possible．This is because molecules will form bonds with molecules on their own side．The inventors say the surfaces of the rubber can be repaired within a week of being separated．
The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris．The organization is part of France’s National Center for Scientific Research．The new material is described in greater detail in the research publication Nature．
小題1:According to the introduction, which of the following is NOT the advantage of the new rubber?
A．It can be made as easily as common rubber．
B．It is environmentally-friendly．
C．It can repair itself at room temperature．
D．It is made of smaller molecules．
小題2:What does the 5th paragraph mainly tell us?
A．Why the new rubber is unique．
B．Why the new rubber can repair itself．
C．The new rubber is made from huge molecules．
D．The new rubber is different from the common rubber．
小題3:If we want to know more about the technology of this kind of new rubber, where can we get the information?
A．In the researchers’ diary．B．In a guide book．
C．In a research magazine．D．In a newspaper．

小題1:D小題1:B小題1:C

小題1:第一題問以下哪項(xiàng)不是新品種橡膠的優(yōu)點(diǎn)，根據(jù)常識(shí)可看出ABC均為優(yōu)點(diǎn)，而D只是一向普通屬性。故選擇D。
小題1: 第二題考察概括能力，問第五段的主要內(nèi)容。從最后一句話the molecules are able to repair themselves at the molecular level可以看出此段主要講述這種橡膠能夠自我修復(fù)的原因。所以選B。
小題1:第三題問我們怎樣獲取更多信息，從最后一段最后一句話The new material is described in greater detail in the research publication Nature可以得知Nature這本雜志（首字母大寫）提供更多信息。所以選C。

Watercolour is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colours found in the earth with water.
Fresco (壁畫), one of the greatest of all art forms, is done with watercolour. It is created by mixing paints and water and applying these to wet plaster (灰泥). Of the thousands of people who stand under Michelangelo’s heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolour painting in the world.
The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolour was used mainly for doing sketches (草圖) or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolour as a serious art form. The English have a widely-known love for outdoors and also small private pictures. The softness of watercolour had a remarkably strong attraction for them.
The popularity of watercolour continued to grow until the twentieth century. The United States passed England as the center for watercolour, producing such well-known watercolour artists as Thomas Eakins and Andrew Wyeth.
小題1: The purpose of the passage is to introduce _____. 
A．the gradual weakness of fresco painting
B．oils’ power or influence over watercolour
C．the discovery of watercolour in England
D．the start and development of watercolour
小題2: In the 16th and 17th centuries the artists thought _____.
A．watercolour was softer, and thus better
B．oil painting lasted longer, and was better
C．watercolour wasn’t fit for finished works
D．watercolour was too hard to use in any works
小題3:According to the passage, watercolour painting was put back in England because ____
A．it was easy to use outdoorsB．it was a strong medium
C．it was extremely bright in colourD．it was suited to popular tastes
小題4:What would the next paragraph most probably deal with?
A．The works of famous US watercolour artistsB．Modern American oil painters
C．The weakness of oils as popular paintsD．Techniques of producing watercolour

In only two decades Asian Americans have become the fastest-growing US minority. As their children began moving up through the nation’s schools, it became clear that a new class of academic achievers was forming. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their educations abroad arrived in the US with a solid grounding in mathematics but little or no knowledge of English.They are also influenced by the promises of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.
Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that causes success, such as ideals that stress family values and emphasize education.
Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the victims of social separation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.
小題1:. While making great achievements at college, Asian-American students ________.
A．feel they are mistreated because of limited knowledge of English
B．a(chǎn)re afraid that their academic successes bear a strong Asian character
C．still worry about unfair treatment in academic areas
D．generally feel it a shame to have to depend on their parents
小題2:. What are the major factors that determine the success of Asian Americans?
A．Solid foundation in basic mathematics and Asian culture.
B．Hard work and intelligence.
C．Hard work and a limited knowledge of English.
D．Asian culture and the American educational system.
小題3:.Few Asian-American students major in human sciences mainly because_________.
A．their English is not good enough
B．they are afraid they might meet with unfair judgment in these areas
C．there is a wide difference between Asian and Western cultures
D．they know little about American culture and society
小題4:. The author’s tone in this passage is __________.
A．sympatheticB．doubtfulC．criticalD．objective

As the world prepares to mark the 100th anniversary of International Women’s Day on March 8, a new report details the progress and challenges girls face in getting an education.
The report – from the Education for All Fast Track Initiative – highlights the importance of girls’ education for economic(經(jīng)濟(jì)的) and social development. It follows progress in Ethiopia, Burkina Faso, Ghana, Guinea, Mauritania, Mozambique and Niger.
Prema Clarke, author of Fast-tracking Girls’ Education, says, “Progress for girls’ education is that they can leave their homes, leave their families and come to a place to study and to learn.  And that’s a big achievement because otherwise these girls have to stay at home, looking after their brothers and sisters, doing the cooking or doing the cleaning.”
She says progress toward the Millennium Development Goals and those of Education for All “is allowing and enabling girls and forcing countries to look at this issue(問題) and to ensure that interventions (干預(yù)) help girls attend school.”
Benefits
Improving education for girls brings many benefits, says Clarke. “It means that girls can then enter the workforce. They can look after their own families much more effectively. They can prevent child death rate. They can educate their own girl children when they begin to expand their own families.” Studies show that having an educated female population helps to improve a country’s health and economic well-being.
Warnings
The report says, “In developing countries, too many girls are not in school, and many girls face continuing health risks and danger just walking to class.”
“Especially in the fragile and post-conflict countries and in many of the African countries, this is a real issue,” she says. Till now, the interventions have been so focused on providing schooling and providing teachers, etc. And now I think there is much more expanded focus on looking at specific（特定的）communities of girls within at-risk groups that now need much more specific attention and much more creative solutions(解決方法) to help them attend school.”
小題1:The underlined word “highlights” in Paragraph 2 probably means ________.
A．showsB．stressesC．remarksD．improves
小題2: According to Clarke, improving education can provide girls with all the opportunities EXCEPT _______.
A．to educate their own girl childrenB．to prevent child death rate
C．to enter the workforceD．to study abroad
小題3:This passage is intended to _____.
A．promote the progress in girls’ education
B．talk about the benefits of improving girls’ education
C．give some information about the education girls are facing
D．sing high praise for the girls’ education
小題4:It can be inferred from the passage that _______.
A．the girls’ educational situation in developing countries is still serious
B．girls were free to go wherever they wanted to in the past
C．there are enough teachers in most of the African countries
D．International Women’s Day was first celebrated on March 8 in 1900

It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
　　As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、職業(yè)) in science.
　　Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
　　These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
　　Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
　　We know a lot about our world, but there are still many answers that we do not have, and we are curious.
小題1:According to the passage, which of the following statements is true?
A．People are curious in the same way.
B．People in different countries are interested in different things.
C．Men and women are curious about different things.
D．People of different ages are interested in different things
小題2:Scientists who work with the biological sciences study____.
A．the earth , the oceans and the sky B．man-made things
C．plants and animals D．ocean water
小題3:When you run, your muscles need ____.
A．more nutrition and oxygenB．more signals
C．more saltD．water
小題4:A rock cracks _____.
A．in wet regions B．in dry regions
C．a(chǎn)t very high or very low temperaturesD．when salty water falls in
小題5:People are always curious because ____.
A．they cannot explain many thingsB．they know nothing about the world
C．they know little about the world D．they want to be scientists

The most exciting kind of education is also the most personal． Nothing can exceed （超越) the joy of discovering for yourself something that is important to you! It may be an idea or a bit of information you come across accidentally—or a sudden insight, fitting together pieces of information or working through a problem． Such personal encounters are the “payoff” in education． A teacher may direct you to learning and even encourage you in it—but no teacher can make the excitement or the joy happen． That's up to you．

20090318

 
A research paper, assigned in a course and perhaps checked at various stages by an instructor, leads you beyond classrooms, beyond the texts for classes and into a process where the joy of discovery and learning can come to you many times． Preparing the research paper is an active and individual process, and ideal learning process． It provides a structure within which you can make exciting discoveries, of knowledge and of self, that are basic to education． But the research paper also gives you a chance to individualize a school assignment, to suit a piece of work to your own interests and abilities, to show others what you can do． Writing a research paper is more than just a classroom exercise． It is an experience in searching out, understanding and synthesizing（綜合）, which forms the basis of many skills applicable（可利用的） to both academic and nonacademic tasks． It is, in the fullest sense, a discovering of an education． So, to produce a good research paper is both a useful and a thoroughly satisfying experience!

To some, the thought of having to write an assigned number of pages, often more than ever produced before, is upsetting． To others, the very idea of having to work independently is threatening． But there is no need to approach paper assignment with anxiety, and nobody should view the research paper as an obstacle to overcome． Instead, consider it a goal to accomplish, a goal within reach if you use the help this book can give you．
小題1:According to the writer, personal discoveries          ．
A．will give one encouragement and direction
B．a(chǎn)re helpful in finding the right information
C．a(chǎn)re the most valuable part of one's personal education
D．will help one to successfully complete school assignments
小題2:It can be inferred from the passage that writing a research paper gives one chances        ．
A．to fully develop one's personal abilities
B．to use the skills learnt in the classroom
C．to prove that one is a productive writer
D．to demonstrate how well one can accomplish school assignment
小題3:The writer argues in the passage that       ．
A．one should explore new areas in research
B．one should trust one's own ability to meet course requirements
C．one should consider research paper writing a pleasure, not a burden
D．one should use all one's knowledge and skills when doing research
小題4:What will probably follow this passage?
A．How to write a research paper．
B．The importance of research in education．
C．How to make new discoveries for oneself．
D．The skill of putting pieces of information together．

Many children first learn the value of money by receiving an allowance (pocket money). The purpose is to let children learn from experiences at an age when financial mistakes are not very costly．
The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration．Some children get a weekly allowance．Others get a monthly allowance．
In any case, parents should make clear what，if anything, the child is expected to pay for with the money．At first, young children may spend all of their allowance soon after they receive it. If they do this，they will learn the hard way that spending must be done within a budget．Parents are usually advised not to offer more money until the next allowance．
The object is to show young people that a budget demands a choice between spending and saving．Older children may be responsible enough to save money for larger costs，like clothing or electronics．Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home．These jobs are a normal part of family life．
Paying children to do extra work around the house，however，can be useful．It can even provide an understanding of how a business works．
Allowances give children a chance to experience the three things they can do with money．They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want．Or they can save it.
Saving helps children understand that costly goals require sacrifice．You have to cut costs and plan for the future．Requiring children to save part of their allowances can also open the door to future saving and investing．Many banks offer services to help children and teenagers learn about personal finance.
A saving account is an excellent way to learn about the power of compound interest．
Compounding works by paying interest on interest．So，for example，one dollar invested at two per-cent interest for two years will earn two cents in the first year．The second years，the money will earn two percent of one dollar and two cents，and so on．That may not seem like a lot．But over time it adds up．
小題1:Giving an allowance, parents should consider all the following EXCEPT_______.
A．how much the child should get each timeB．whether the child has made a budget
C．where the money really goesD．how often a child can get it
小題2:The author of the passage holds the opinion that________.
A．what children learn by handling allowances may be beneficial in the future
B．children can learn to set up their own business with their allowances
C．keeping allowances in the bank is the best choice for children
D．it is not a good idea to pay children for housework at home
小題3:The underlined words “compound interest” in the passage probably mean ________.
A．increasing curiosity to learn how to make more money
B．stronger power to hold one’s attention to saving money
C．money paid by the bank on your original money and the gain from it
D．the sum of money that you earn from keeping your money in the bank
小題4:What is the best title for the passage?
A．Be Generous to Pay Your Children．B．Be Wise to Avoid Financical Mistakes．
C．Saving Allowances Does Good to Children.D．Allowances Help Children Learn about Money．

Perhaps a parent’s most important contribution toward raising a trustful child is to develop a relationship founded on trust. A child of any age will feel proud and grown-up if parents frequently show their trust. In court a defendant(被告) is innocent until proved guilty. But in the family, a teenager “defendant” is too often assumed guilty.
Even when the child is caught in a complete lie, this should not be the end of trust. A parent can tell a child that a single lie is forgivable. Yet it should be clear that if lies continue, the child, like the boy who cried wolf, will suffer loss of trust.
When my wife and I discovered that our son Tom, then 13, had lied about throwing a party while we were away, we grounded him for a month. We also told Tom that we could no longer trust him, and we could not allow him to stay alone overnight again. This loss of freedom was an important lesson; he learned how hard it is to live with people when they don’t trust him. As a result, now more than three years later we can again trust Tom to stay alone overnight.
Parents must always remember there is no easy answer to this universal problem of lying. We can set a good example, allow for privacy, monitor friendship, develop trust and punish wrong doing, but still we discover our child has lied to us. Finally that’s why there is a need for trust on both sides of a parent-child relationship. Lying destroys closeness and friendship. For that reason, parents should always try to give a child the feeling that they can be trusted with the truth. Parents may start with a child’s trust, but as the child grows older, parents must earn it.
小題1:When the writer and his wife discovered that their son had lied, they _________.
A．took all his freedom from him
B．decided never to trust him again
C．forbade him to stay alone overnight
D．a(chǎn)rranged him to stay at home.
小題2:We can infer from the passage that very often ________.
A．parents don’t trust their child as they should
B．defendants are usually proved not guilty in court
C．parents have too much trust in their child
D．some children are founded guilty in court
小題3:According to the passage, the writer believes that _____________.
A．parents shouldn’t punish their children even if they lie
B．it is not easy to deal with the problem of lying as parents
C．there are effective ways to prevent children from lying
D．children will stop telling lies as they grow up
