In 2015 these ants were joined in the desert by scientists from two Belgian universities, who spent a month in the 28 heat tracking the ants and digging out their nests. The goal was simple, to discover how the 29 adapted to the kind of heat that can 30 melt the bottom of shoes.Back in Belgium, the scientists looked at the ants under an electronic microscope and found that their 31 triangular hair reflects light like a prism (棱镜), giving them a metallic reflection and protecting them from the sun’s awful heat.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The start of high school doesn’t have to be stressful[A] This month, more than 4 million students across the nation will begin high school. Many will do well. But many will not. Consider that nearly two-thirds of students will experience the “ninth- grade shock,” which refers to a dramatic drop in a student’s academic performance. Some students cope with this shock by avoiding challenges. For instance, they may drop difficult coursework. Others may experience a hopelessness that results in failing their core classes, such as English, science and math.[B] This should matter a great deal to parents, teachers and policymakers. Ultimately it should matter to the students themselves and society at large, because students’ experience of transitioning (过渡) to the ninth grade can have long-term consequences not only for the students themselves but for their home communities. We make these observations as research psychologists who have studied how schools and families can help young people thrive.[C] In the new global economy, students who fail to finish the ninth grade with passing grades in college preparatory coursework are very unlikely to graduate on time and go on to get jobs. One study has calculated that the lifetime benefit to the local economy for a single additional student who completes high school is half a million dollars or more. This is based on higher earnings and avoided costs in health care, crime, welfare dependence and other things.[D] The consequences of doing poorly in the ninth grade can impact more than students’ ability to find a good job. It can also impact the extent to which they enjoy life. Students lose many of the friends they turned to for support when they move from the eighth to the ninth grade. One study of ninth-grade students found that 50 percent of friendships among ninth graders changed from one month to the next, signaling striking instability in friendships.[E] In addition, studies find the first year of high school typically shows one of the greatest increases in depression of any year over the lifespan. Researchers think that one explanation is that ties to friends are broken while academic demands are rising. Furthermore, most adult cases of clinical depression first emerge in adolescence (青春期). The World Health Organization reports that depression has the greatest burden of disease worldwide, in terms of the total cost of treatment and the loss of productivity.[F]Given all that’s riding on having a successful ninth grade experience, it pays to explore what can be done to meet the academic, social and emotional challenges of the transition to high school. So far, our studies have yielded one main insight: Students' beliefs about change--their beliefs about whether people are stuck one way forever, or whether people can change their personalities and abilities--are related to their ability to cope, succeed academically and maintain good mental health. Past research has called these beliefs “mindsets (思维模式),” with a “fixed mindset” referring to the belief that people cannot change and a “growth mindset” referring to the belief that people can change.[G]In one recent study, we examined 360 adolescents’ beliefs about the nature of“smartness”--that is, their fixed mindsets about intelligence.. We then assessed biological stress responses for students whose grades were dropping by examining their stress hormones(荷尔蒙).Students who believed that intelligence is fixed--that you are stuck being“not smart” if you struggle in school--showed higher levels of stress hormones when their grades were declining at the beginning of the ninth grade. If students believed that intelligence could improve -- that is to say, when they held more of a growth mindset of intelligence--they showed lower levels of stress hormones when their grades were declining. This was an exiting result because it showed that the body’s stress responses are not determined solely by one’s grades. Instead, declining grades only predicted worse stress hormones among students who believed that worsening grades were a permanent and hopeless state of affairs.[H]We also investigated the social side of the high school transition. In this study, instead of teaching students that their smartness can change, we taught them that their social standing--that is, whether they are bullied or excluded or left out - can change over time. We then looked at high school students’ stress responses to daily social difficulties. That is, we taught them a growth mindset about their social lives. In this study, students came into the laboratory and were asked to give a public speech in font of upper-year students. The topic of the speech was what makes one popular in high school. Following this, students had to complete a difficult mental math task in front of the same upper-year students.[I]Experiment results showed that students who were not taught that people can change showed poor stress responses. When these students gave the speech, their blood vessels contracted and their hearts pumped less blood through the body -- both responses that the body shows when it is preparing for damage or defeat after a physical threat. Then they gave worse speeches and made more mistakes in math. But when students were taught that people can change, they had better responses to stress, in part because they felt like they had the resources to deal with the demanding situation. Students who got the growth mindset intervention (干预) showed less-contracted blood vessels and their hearts pumped more blood- both of which contributed to more oxygen getting to the brain, and, ultimately, better performance on the speech and mental math tasks.[J]These findings lead to several possibilities that we are investigating further. First, we are working to replicate (复制) these findings in more diverse school communities. We want to know in which types of schools and for which kinds of students these growth mindset ideas help young people adapt to the challenges of high school. We also hope to learn how teachers, parents or school counselors can help students keep their ongoing academic or social difficulties in perspective. We wonder what would happen if schools helped to make beliefs about the potential for change and improvement a larger feature of the overall school culture, especially for students staring the ninth grade.36. The number of people experiencing depression shows a sharp increase in the first year of high school.37. According to one study, students’ academic performance is not the only decisive factor of their stress responses.38. Researchers would like to explore further how parents and schools can help ninth graders by changing their mindset.39. According to one study, each high school graduate contributes at least 500,000 dollars to the local economy.，40. In one study, students were told their social position in school is not unchangeable.41. It is reported that depression results in enormous economic losses worldwide.42. One study showed that friendships among ninth graders were far from stable.43. More than half of students will find their academic performance declining sharply when they enter the ninth grade.44. Researchers found through experiments that students could be taught to respond to stress in more positive way.45. It is beneficial to explore ways to cope with the challenges facing students entering high school.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Educators and business leaders have more in common than it may seem. Teachers want to prepare students for a successful future. Technology companies have an interest in developing a workforce with the STEM (science, technology, engineering and math) sills needed to grow the company and advance the industry. How can they wok together to achieve these goals? Play may be the answer.Focusing on STEM skills is important, but the reality is that STEM sills are enhanced and more relevant when combined with traditional, hands-on creative activities. This combination is proving to be the best way to prepare today’s children to be the makers and builders of tomorrow. That is why technology companies are partnering with educators to bring back good, old-fashioned play.In fact many experts argue that the most important 2lst-century skills aren’t related to specific technologies or subject matter, but to creativity; skills like imagination, problem-finding and problem-solving, teamwork, optimism, patience and the ability to experiment and take risks. These are skills acquired when kids tinker (鼓捣小玩意), High-tech industries such as NASA’s Jet Propulsion Laboratory have found that their best overall problem solvers were master tinkerers in their youth.There are cognitive (认知的) benefits of doing things the way we did as children—building something, tearing it down, then building, it up again. Research shows that given 15 minutes of free pay, four- and five-year-olds will spend a hid of this time engaged in spatial, mathematical，and architectural activities. This type of play—especial with building blocks--helps children discover and develop key principles in math and geometry.If play and building are critical 1o 2lst century skill development, that’s really good news for two reasons: Children are born builders, makers, and creators, so fostering(培养) 2lst-centary skills may be as simple as giving kids room to play, tinker and try thing out,even as they growolder, Secondly, it doesn't take 21st-century technology to foster 2lst-century skills. This is especially important for under-resourced schools and communities. Taking whatever materials are handy and tinkering with them is a simple way to engage those important “maker” skills. And anyone, anywhere. can do it.46. What docs the author say about educators?A) They seek advice from technology companies to achieve teaching goals.B) They have been successful in preparing the workforce for companies.C) They help students acquire the skills needed for their future success.D) They partner with technology companies to enhance teaching efficiency.47. How can educators better develop students’ STEM skills, according to the author?A) By blending them with traditional, stimulating activities.B) By inviting business leaders to help design curriculums.C) By enhancing students’ ability to think in a critical way.D) By showing students the best way to learn is through play.48. How do children acquire the skills needed for the 21st century?A) By engaging in activities involving specific technologies.B) By playing with things to solve problems on their own.C) By familiarizing themselves with high-tech gadgets.D) By mastering basic principles through teamwork.49. What can we do to help children learn the basics of math and geometry?A) Stimulate their interest as early as possible.B) Spend more time playing games with them.C) Encourage them to make things with hands.D) Allow them to tinker freely with calculators.50. What does the author advise disadvantaged schools and communities to do?A) Train students to be makers to meet future market demands.B) Develop students’ creative skills with the resources available.C) Engage students with challenging tasks to foster their creativity.D) Work together with companies to improve their teaching facilities.Passage TwoQuestions 51 to 55 are based on the following passage.Being an information technology, or IT, worker is not a job I envy. They are the ones who, right in the middle of a critical meeting, are expected to instantly fix the projector that’s no longer working. They have to tolerate the bad tempers of colleagues frustrated at the number of times they've had to call the help desk for the same issue. They are also the ones who know there are systems that are more powerful, reliable and faster, but their employer simply will not put up the funds to buy them.According to a recent survey, employees who have a job reliant on IT support consider IT a major source of job dissatisfaction. Through no fault of they own, they can suddenly find their productivity deteriorating or quality control non-existent. And there’s little they can do about it.The experience of using IT penetrates almost the entire work field. It has become a crucial part of employees’ overall work experience. When IT is operating as it should, employee self-confidence swells. Their job satisfaction, too, can surge when well-functioning machines relieve them of dull tasks or repetitive processes. But if there’s one thing that triggers widespread employee frustration, it’s an IT transformation project gone wrong, where swollen expectations have been popped and a long list of promised efficiencies have been reversed.This occurs when business leaders implement IT initiatives with little consideration of how those changes will impact the end user.Which is why managers should appreciate just how influential the IT user experience is to their employees, and exert substantial effort in ensuring their IT team eliminates programming errors and application crashes. Adequate and timely IT support should also be available to enable users to cope with technological issues at work. More importantly, IT practitioners need to understand what employees experience mentally when hey use IT.Therefore, businesses need to set up their IT infrastructure so that it is designed to fit in with their employees’ work, rather than adjust their wok to fit in with the company’s IT limitations.51. What does the author say about working in IT?A)It is envied by many.B) It does not appeal to him.C It is financially rewarding.D) It does not match his abilities.52. What is the finding of a recent survey on employees who have a job reliant on IT support?A) IT helps boost productivity.B) IT helps improve quality control.C) Many employees are deeply frustrated by IT.D) Most employees rely heavily on IT in their work.53. What is said to happen when IT is functioning properly?A) There is a big boost in employees’ work efficiency.B) Employees become more dependent on machines.C) There are no longer any boring or repetitive tasks.D) Employees become more confident in their work.54. What should business leaders do before implementing new IT initiatives?A) Consider the various expectations of their customers.B) Draw up a list of the efficiencies to be promised.C) Assess the swollen cost of training the employees.D) Think about the possible effects on their employees.55. How can a business help improve its employees' experience in using IT?A) By designing systems that suit their needs.B) By ensuring that their mental health is sound.C) By adjusting their work to suit the 1T system.D) By offering them regular in-service training.Part Ⅳ Translation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

They are not only dwellers in nature, but also transformers of it. With the development of society and its economy, people tend to become less dependent on nature directly, but indirectly their dependence grows. Human beings are connected with nature by "blood" ties. No one can live outside nature. However, the previous dynamic balancebetween man and nature has shown signs of breaking down. Problems such as the population explosion, ecological imbalance and the shortage of natural resources have become major factors keeping human society from being further developed. Professor Spirkin holds that the only choice for human beings is the wise organization of production and care for Mother NatureSample EssayMy Understanding of Environmental ProtectionMan and the environment are closely related. Man relies on the environment for water, food and shelter. A harmonious relationship between man and the environment is essential for human survival on the earth.However, man and the environment have never been on such bad terms as they are now. As society develops, man’s transformation of nature has severely polluted his living environment. Deforestation leads to changes in rainfall patterns,causing devastating floods, droughts and sandstorms. The discharge of chemicalPollutants endangers our health and the lives of other beings. And mass production has resulted in the shortage of irreplaceable natural resources such as coal and oil. If we take no immediate and effective steps to protect our environment, human being may be the next species to become extinct.We should do our best to protect our environment by planting more trees, taking care of wildlife, reducing industrial wastes, using renewable energy, and imposing heavy fines on environmentally-unfriendly activities, so as to preserve the environment for future generations.友情提示：部分文档来自网络整理，供您参考！文档可复制、编辑，期待您的好评与关注！。

AIf humans pump enough carbon dioxide (CO2) into the atmosphere, the stratocumulus clouds(层积云) could disappear, and the earth's temperature could climb sharply to heights not predicted in current climate models. It would burn the planet. That's the conclusion of a paper published in the journal Nature Geoscience and described in detail by Natalie Wolchover for Quanta Magazine.As Wolchover explained, clouds have long been one of the great uncertainties of climate models. Computer models that easily capture the complexity and detail of most climate systems just aren't powerful enough to predict worldwide changes in cloud behavior. But clouds are important. They reflect sunlight away from the earth's surface. And stratocumulus clouds are those white blankets you might have seen as you looked out the window of arm airplane, rolling out below you and hiding the ground Researchers suspect that certain sudden, past jumps intemperature may have been caused by changes to clouds like these.For the new research, scientists modeled just a small patch of sky using a supercomputer. Array They found that if carbon dioxide levels reach about 1, 200 parts per million(ppm) in the atmosphere, stratocumulus clouds break up. That's a very high carbon dioxide concentration. Right now, levels have climbed past 410 ppm--a dangerous change from 280 ppm before the Industrial Revolution.But humans put more and more CO2 into the atmosphere every year. If current trends continue, the earth could reach 1, 200 ppm within 100 to 150 years. This could happen if our society doesn't follow through on any of its commitments to reduce emissions(排放), Wolchover reported. And even if it does, the result would be another 8 degrees Celsius of heat added to the global average, on top of the dangerous changes already underway due to greenhouse gases.That’s an enormous change, and it goes beyond predictions of worldwide ice melt and catastrophic sea level rise. And, once the stratocumulus clouds are gone, Wolchover reported, they likely wouldn't reappear until atmospheric carbon dioxide levels dropped below where they are currently.There's still some uncertainty in the data. The 1, 200 ppm figure could change as scientists look into the issue further.1、What can we learn from paragraph 2?A．Most climate systems are not complex.B．Cloud behavior is uncertain and hard to predict.C．Temperature changes affect the stratocumulus clouds.D．The stratocumulus clouds protect planes from sunlight.2、How did the scientists study clouds in the new research?A．By measuring the sea level.B．By experimenting in a natural state.C．By comparing climate models.D．By computer modeling and analyzing.3、What does "it" refer to in paragraph 4?A．The atmosphere.B．The earth.C．Our society.D．The result.

第2次作业一、阅读理解（本大题共100分，共 5 小题，每小题 20 分）1.Hunger is no novelty. We can discount legends of golden ages, landsof Cockayne, and Mefgasthenes' statement that before Alexander's invasion of India, there had never been famine or food shortage there. Trustworthy historical records show that during the Renaissance one year in ten in Britain, and one in five in Europe, was a famine year. China, with a greater area and more diverse climate, had a famine in some region every year.Famine is a state of affairs in which people are dying in the streets. It therefore attracts the notice of historians and is recorded. The fact that it strikes people who are aware of having been properly fed and well is more important. Not only are the survivors more resilient, they are also angry at the breakdown of the system and eager to do something about it though it is obvious from the record that they do not always have the means. Malnutrition is much more insidious. It is a chronic state in which the total food supply or, more often, the supply of certain components such as protein or some of the vitamins, is inadequate. It seems probable that, either constantly or seasonally. It used to be the usual condition of mankind and was regarded as normal. The rickety appearance of the figures in medieval paintings and drawings is often put down to the incompetence of the artist: it is as likely that most people really did look like that. The exuberance with which poets greeted the "merry month of May" may, in our dull climate, have had a meteorological basis: it is just as likely that in May, after six months' shortage, there was now an adequate vitamin supply. The promptness with which some sailors succumbed to scurvy after leaving port suggests that they were normally on the edge of scurvy and needed only a slight worsening of conditions to get it acutely. Others will think of other examples. Hunger and malnutrition are components, of a classic example of a vicious cycle. They lead to enfeeblement or apathy in which nothing either can be done, or seems to be worth doing, to alter the state of affairs; this leads to more hunger and malnutrition. There is good reason to think that, in much of the developing world, if the cycle could once the broken, it would never return.(1).According to the text, hunger in the past ____.A.occurred more frequently in Britain than in the rest of EuropeB.was less of a problem than it is todayC.was almost unknown in the Indian subcontinentD.was quite a regular occurrence(2).The writer suggests that famine is different from malnutrition because ____.A.it is a far more widespread problemB.it causes rather more people to dieC.it arouses a desire for action rather than mere apathyD.it tends to affect the rich and well fed more than the poor(3).What does the writer say about malnutrition?____A.It was a common condition in the Middle Ages.B.It arouses a great deal of emotion and interest.C.It affected the competence of medieval artists.D.It is a more obvious problem than famine.(4). The writer says that many sailors in the past succumbed rapidly to scurvy because ____.A.they did not have enough to eatB.they were not used to living at seaC.they were already suffering from malnutritionD.they caught it from other sailors(5). According to the writer, the vicious circle of malnutrition in developing countries ____.A.makes long-term progress very difficult to achieveB.could be broken for good if it were broken onceC.has a significant effect on the developed countriesD.could extend to developed countries in the future2.One of the most fascinating questions about human behavior is each person is different from all others. The answer to this question would explain the aspect of human nature called personality. Some theories assume that inborn characteristics determine human personality. Many observers have hypothesized that each person has a dominant temperament, present from birth, that influences his or her behavior during an entire lifetime. According to one of these theories, people can be classified into four basic types: sanguine, choleric, phlegmatic and melancholic. Each type or temperament is characterized by a unique set of possible strengths and possible weaknesses.Sanguine people are described as the most outgoing of the four temperaments. They are warm, fun-loving, and like the company of others. Because of these strengths, it is said that sanguines often make good salesmen, actors, or public speakers. Sanguines, however, may have some serious weaknesses. Their problems often come from their lack of discipline. Easily distracted, they often lack the concentration to complete a job or follow through on a promise. For this reason, other people may not trust them.Choleric people, are quite different from the carefree, emotional sanguines. Because of their strong will, decisiveness, and productivity, cholerics are natural leaders who are good at making vast plans and motivating other people to help them carry out their plans. They are often successful in business, industry, or politics. Choleric weaknesses can be very damaging, however. Because a strong desire to lead, they can be cruel and cold toward those who do not wish to follow. They often do not listen to advice from others, and once they make a decision, they may become hostile toward anyone who questions that decision.Phlegmatics are calm, easygoing people who strive for efficiency and organization. Very diplomatic and polite, they make people feel comfortable and generally help keep things running smoothly. Forthese reasons, they make good teachers, technicians, etc. Phlegmatics, however, often have weaknesses that keep them from becoming successful. Afraid to take chances, they may let opportunities go by. In fact, they may avoid taking any steps to improve their position in life.Melancholics are often considered to be gifted persons who possess creative talent. They are very analytical and able to understand complicated processes and to note detail. These people can make good doctors, scientists, artists, writers, and musicians. Melancholicsare also said to be loyal, idealistic and self-sacrificing. However, melancholics frequently make themselves miserable because they tendto be negative and critical, and put up inflexible standards. They attach importance to everything they do, so they worry too much and see problems everywhere, and complain too much. They often become disappointed because neither they nor the people around them can live up to their high standards.Explaining human personality in terms of innate temperaments is a theory that has not been generally accepted by psychologists. They criticize it for being too simplistic and unscientific. This may be so; however, present-day psychologists have been unable to formulatea single theory.(1).The word "dominant" probably means ____.A.primaryB.minorC.greatD.insignificant(2).Outgoing are those sanguine people ____.A.who like to be in big firms or corporations B.who are emotional and carefreeC.who enjoy the habit of making fun of others D.who can be good businessmen(3).What are said to be the most important features of Choleric people?____A.Cruel but sympathetic.B.Decisive and cold.C.Hostile and fun-loving.D.Strong-willed and polite.(4).Who are likely to be rejected by a bright-future project?____A.Cholerics.B.Sanguines.C.Melancholies.D.Phlegnatics.(5).Why is each person different from all others?___A.Because of their psychology.B.Because of their different background.C.Because of their various body temperature.D.Because of their innate personalities.3.Chicago taxpayers paid $ 30 an hour to provide reputed mob (黑帮) boss Joseph Lombardo with his own personal chauffeur, They also paid city workers who ran business, conducted shake-downs, went to the racetrack and even committed a jewel robbery on city time. All of this occurred in the city's scandal-ridden Department of Streets and Sanitation (卫生). "There's always been a link between the mob and the Department of Streets and Sanitation," said Jerry Gladden, investigator of the Chicago Crime Commission. "The hoods sign in and leave. They get health benefits and a paycheck. It's a common practice."According to the results of an investigation conducted by City Inspector General Alexander Vroustouris, a sanitation department foreman by the name of Chirs Spina used city crews to clear out city-owned scrap metal (废金属) on department property and sold the scrap to private scrap yards. In addition, the Vroustouris investigationreports, Spina, who was paid $ 20 an hour by Streets and Sanitation, was spotted driving Lombardo around the city during working hours. He even filled for overtime payments for the chauffeuring duties. Spina has since been fired.(1).The main content of this passage is about ____.A.that Chicago taxpayers paid money to mobsB.the corruption of city officialsC.an investigation of Department of Streets and SanitationD.a driver who drove for mobs(2).The word "Samaritans" (Para 3) refers to ____.A.employers in the Plumbing CompanyB.Gill and JonesC.rescuing crewD.workers in the construction site(3).The word "cave-ins" (Para 4) means ____.A.in the caveB.in a holeC.in a ditchD.falling down(4).Why was the Plumbing company fined?____A.Because its employees did not take precautions.B.Because it did not rescue effectively.C.Because it did not provide hard hats for the employees.D.Because it failed to build the trench wall firmly.(5).What can we learn from this passage?____A.Kaufman should not walk under the trench wall.B.Gill should wear hard hats while rescuing.C.Kempthorne will use this example in legislation.D.OSHA were doing their job bookishly.4.Large companies need a way to reach the savings of the public. The same problem, on a smaller scale, faces practically every company trying to develop new products and create new jobs. There can belittle prospect of raising the sort of sums needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling to provide money on a permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the businessin exchange for a share in future profits. This they do by issuing stocks and shares in the business through the Stock Exchange. Bydoing so they can put into circulation the savings of individuals and institutions, both at home and overseas.When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker to some other saver who is seeking to invest his money.Many of the services needed both by industry and by each of us are provided by the Government or by local authorities. Without hospitals, roads, electricity, telephones, railway, this country could not function. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The Government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and they, too, cometo the Stock Exchange.There is hardly a man or woman in this country whose job or whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another this new money must come from the savings of the country. The Stock Exchange exists to provide a channel through which thesesavings can reach those who need finance.(1).Almost all companies involved in new production and development must ____.A.rely on their own financial resourcesB.persuade the banks to provide long-term financeC.borrow large sum of money from friends and people they knowD.depend on the population as a whole for finance(2).The money which enables those companies to go ahead with their projects is ____.A.repaid to its original owners as soon as possibleB.raised by the selling of shares in the companiesC.exchanged for ownership in The Stock ExchangeD.invested in different companies on The Stock Exchange(3).When the savers want their money back they ____.A.ask another company to obtain money for themB.look for other people to borrow money fromC.put their shares in the company back on the marketD.transfer their money to a more successful company(4).All the essential services on which we depend are ____.A.run by the Government or our local authoritiesB.in constant need of financial supportC.financed wholly by rates and taxesD.unable to provide for the needs of the population(5).The Stock Exchange makes it possible for the Government, local authorities and nationalized industries ____.A.to borrow as much money as they wishB.to make certain everybody saves moneyC.to raise money to finance new developmentD.to make certain everybody lends money to them5.How much paper do you use every year? Probably you can't answer that question quickly. In 1990 the world's use of paper was about one kilogram for each person in a year. Now some countries use as much as50 kilograms of paper for each person in a year. The amount of papera country uses shows how far advanced the country is, some people say. It is difficult to say whether this is true: different people mean different things by the word 'advanced'. But countries like theUnited States, England and Sweden certainly use more paper than other countries.Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before the year 1400. The Egyptians wrote on papyrus. Europeans used Parchment for many hundreds of years. Parchment was very strong; it was made from the skin of.Certain young animals. We have learnt some of the most importantfacts of European history from records that were kept on parchment.The Chinese first made paper about 2000 years ago. China still has pieces of paper which were made as long ago as that. But Chinesepaper was not made from the wood of trees. It was made from the hair-like parts of certain plants.Paper was not made in southern Europe until about the year 1100. Scandinavia which now makes a great deal of the world's paper, didnot begin to make it until 1500. It was a German named Schaeffer who found out that one could make the best paper from trees. After that, the forest countries of Canada, Sweden, Norway Finland and the United States became the most important in papermaking. Today in Finland, which makes the best paper in the world, the paper industry is the biggest in the land. New papermaking machines are very big, and they make paper very fast. The biggest machines can make a piece of paper 300 metres long and six metres wide in one minute.When we think of paper, we think of newspaper, books, letters, envelopes, and writing paper. But there are many other uses. Onlyhalf of the paper that is made is used for books and newspapers, etc.Paper is very good for keeping you warm. Houses are often insulated with paper. You have perhaps seen homeless men asleep on a large number of newspapers. They are insulating themselves against the cold. In Finland, where in winter it is sometimes - 40℃centigrade, the farmers wear paper boots in the snow. Nothing could be warmer.Each year, more and more things are made of paper. We have had paper cups, plates, and dishes for a long time. But now we hear that chairs, tables, and even beds can be made of paper. With paper boots and shoes, you can wear paper hats, paper dresses, and paper raincoats. When you have used them once, you throw them away and buy new ones.The latest in paper seems to be paper houses. These are not small houses for children to play in, but real, big houses for people tolive in. You can buy a house with three chief rooms, for about $500. You can put it up yourself in a few hours, and you can use it for about five years.People have made paper boats, but they have not yet made paper aeroplanes or cars. Just wait - they probably will.(1).____use more paper than other countries.A.China, England and SwedenB.The United States, England and FinlandC.The United States, England and SwitzerlandD.The United States, England and Sweden(2).We have learnt some of the most important facts of European history from records that were kept on ____.A.papyrusB.paperC.booksD.parchment(3).Chinese paper was once made from ____.A.the wood of treesB.the hair-like parts of certain plantsC.the grass-like plant which grows near waterD.the skins of certain animals(4).Paper was not made in southern Europe until ____.A.about the year 1400B.about the year 1500C.about the year 1100D.about the year 1900(5)."Nothing could be warmer."
