When John and Victoria Falls arrived in New York City for one-year stay, they did not bring very many things with them. They had planned either to live in a furnished apartment or to buy used furniture. But they soon learned about a new system that more and more people are using. The renting of home furnishings (bed, tables, dishes, and so on) has become one of America’s fastest growing businesses.What kinds of people rent tent officials, foreign students, airline workers, young married couples - people whose job or buw homes. Young people with little money do not want to buy cheap furniture that they may soon dislike. They prefer to wait until they have enough money to buy furniture they really like. Meanwhile, they find they can rent better quality furniture than they could afford to buy.One family, who now have a large, beautiful home of their own, liked their rented furniture so much that they decided to keep renting it instead of buying new things. But usually people don’t like to tell others about it. The idea of renting home furnishings is still quite new, and they are not sure what their neighbors might think.11.Which of the following has become one of America’s fastest growing businesses?A.Selling home furnishings.B.Renting furnished apartments.C.Selling used furniture.D.Renting home furnishings.12.Why do some people prefer to rent furniture?A.Because the furniture they get in this way is new.B.Because it saves them a lot of money.C.Because it saves them much trouble and money.D.Because they can always get better quality furniture in this way.13.What can you infer from the passage?A.The idea of renting furniture is not acceptable.B.Renting furniture is not popular in the couple’s home town.C.Only those who don’t have enough money to rent furniture.D.People usually grow to like the furniture they have rented.14.Which of the following can best serve as the title of the passage?A.Rent or Buy?B.A New Way of Getting Home Furnishings.C.Furnished Apartments.D.A New Idea.15.Young people liked renting home furniture because_________A.they have less money.B.they don’t want to buy old furniture.C.the new furniture is of good quality.D.they don’t have much money and don’t want to buy the cheap furniture.
DThe Cost of Higher EducationIndividuals (个人) should pay for their higher education.A university education is of huge and direct benefit to the individual. Graduates earn more than non-graduates. Meanwhile, social mobility is ever more dependent on having a degree. However, only some people have it. So the individual, not the taxpayers, should pay for it. There are pressing calls on the resources (资源) of the government. Using taxpayers' money to help a small number of people to earn high incomes in the future is not one of them.Full government funding (资助) is not very good for universities. Adam Smith worked in a Scottish university whose teachers lived off student fees. He knew and looked down upon 18th-century Oxford, where the academics lived comfortably off the income received from the government. Guaranteed salaries, Smith argued, were the enemy of hard work; and when the academics were lazy and incompetent, the students were similarly lazy.If students have to pay for their education, they not only work harder, but also demand more from their teachers. And their teachers have to keep them satisfied. If that means taking teaching seriously, and giving less time to their own research interests, that is surely something to celebrate.Many people believe that higher education should be free because it is good for the economy (经济). Many graduates clearly do contribute to national wealth, but so do all the businesses that invest (投资) and create jobs. If you believe that the government should pay for higher education because graduates are economically productive, you should also believe that the government should pay part of business costs. Anyone promising to create jobs should receive a gift of capital from the government to invest. Therefore, it is the individual, not the government, who should pay for their university education.68. The underlined word "them" in Paragraph 2 refers toA. taxpayersB. pressing callsC. college graduatesD. government resources

Passage FourStudents all over the world have to work for their education. A college education in the United States isexpensive. The costs are so high that most families begin to save for their children's education when their children are babies. Even so, many young people cannot afford to pay the expenses of full-time college work. They do not have enough money to pay for school costs. Tuition for attending the university, books for classes, and living expenses are high. There are other expenses such as chemistry and biology lab fees and special student activity fees for such things as parking permits and football tic, kets. The cost of college education increases every year. However, classrooms are still crowded with students. Some American students have scholarships or other support, but many do not.Students from other countries have money problems to overcome, too. Because students in most international programs need to have a sponsor, they work hard to earn scholarships or special loans. International students understand the value of going to school in another country. They also know that it is difficult. Yet just as Americans choose to attend American universities in spite of the difficulty, however, it is usually possible for students from abroad to work on university campuses to pay for some of the costs of their education. Some people believe that students value their education more if they work for it.48. Tuition for attending the university in the United States is ______.A. inexpensiveB. highC. free from chargeD. costless

The money that we've saved isn't nearly enough.The McGaritys have money, but they are show-offs with it. The McGarity girl just yesterday stood out there in the street eating from a bag of cookies while a group of hungry children watched her. I saw those children looking at her and crying in their hearts, and when she couldn't eat any more, she threw the rest down the sewer (阴沟).Miss Jackson who teaches at the Settlement House (教育中心) isn’t rich, but she knows things, she understands people. Her eyes look straight into yours when she talks with you. Everyboby else here looks away because they'rs ashamed of their lives. I'd like to see the children be like Miss Jackson when they grow up.41. The writer suggests that her family______.A. is extremely richB. is an unhappy oneC. live with nice and kind peopleD. long for a change in their life
Passage ThreeMy husband and children feel very happy to live here. They can't see that we live on a dirty street in a dirty house among people who aren't good.

The money that we've saved isn't nearly enough.The McGaritys have money but they are so proud. They look down upon the poor The McGarity girl just yesterday stood out there in the street eating from a bag of candy while a ring of hungry children watched her. I saw those children looking at her and crying in their hearts; and when she couldn't eat any more she threw the rest down the sewer (下水道). Why? Is it only because they have money? There is more to happiness than money in the world, isn't there?Miss Jackson who teaches at the Settlement House isn't rich, but she knows things. She understands people.

共用题干第一篇Gross National HappinessIn the last century,new technology improved the lives of many people in many countries.However,one country resisted these changes.High in the Himalayan mountains of Asia,the kingdom of Bhutan remained separate. Its people and Buddhist（佛教）culture had not been affected for almost a thousand years. Bhutan, however,was a poor country.People died at a young age.Most of its people could not read,and they did not know much about the outside world.Then,in 1972,a new ruler named King Jigme Singye Wangchuck de- cided to help Bhutan to become modern,but without losing its traditions.King Wangchuck looked at other countries for ideas.He saw that most countries measured their progress by their Gross National Product(GNP).The GNP measures products and money. When the number of products sold increases,people say the country is making progress.King Wangchuck had a different idea for Bhutan. He wanted to measure his country's progress by people's happiness.If the people's happiness increased, the king could say that Bhutan was making progress.To decide if people were happier,he created a measure called Gross National Happiness(GNH).GNH is based on certain principles that create happiness.People are happier if they have health care, education,and jobs.They are happier when they live in a healthy,protected environment. They are happier when they can keep their traditional culture and customs.Finally,people are happier when they have a good,stable government.Now there is some evidence of increased GNH in Bhutan.People are healthier and are living longer. More people are educated and employed.Twenty-five percent of the land has become national parks,and the country has almost no pollution. The Bhutanese continue to wear their traditional clothing and follow their ancient Buddhist customs.Bhutan has also become a democracy.In 2008,King Wangchuck gave his power to his son.Although the country still had a king,it held its first democratic elections that year. Bhutan had political parties and political candidates for the first time.Finally,Bhutan has connected to the rest of the world through television and internet.Bhutan is a symbol for social progress.Many countries are now interested in Bhutan's GNH.These countries are investigating their own ways to measure happiness.They want to create new policies that take care of their people,cultures,and land.Brazil may be the next country to use the principles of GNH.Brazilian leaders see the principles of GNH as a source of inspiration.Brazil is a large country with a diverse population.If happiness works as a measure of progress in Brazil,perhaps the rest of the world will follow.A country shows its progress with GNP by____________.A:spending more moneyB:spending less moneyC:providing more jobsD:selling more products

When countries develop economically,people live longer lives.Development experts have long Delieved this is because having more money expands lifespan,but a massive new study suggests that education may play a bigger role.The finding has huge implications for public health spending.Back in 1975,economists plotted rising life expectancies against countries'wealth,and concluded that wealth itself increases longevity.It seemed self-evident:everything people need to be health from food to medical care--costs money But soon it emerged that the data didn't always fit that theory.Economic upturns didn’t always mean longer lives.In addition,for reasons that weren't clear,a given gain in gross domestic product（GDP）caused increasingly higher gains in life expectancy over time,as though it was becoming cheaper to add years of life.Me moreover,in the 1980s researchers found ga ins in literacy were associated with greater increases in life expectancy than gains in wealth were Finally,the more educated people in any country tend to live longer than their less educated compatriots.But such people also tend to be wealthier,so it has been difficult to untangle which factor is increasing lifespan Permanent change Wolfgang Lutz of the International Institute for Applied Systems Analysis in Vienna and colleagues have now done that by compiling average data on GDP per person,lifespans,and years of education from 174 countries,dating from 1970 to 2010 They found that,Just as in 1975,wealth correlated with longevity.But the correlation between longevity and years of schooling was closer,with a direct relationship that did not change over time way wealth does When the team put both these factors into the same mathematical model,they found that differences in education closely predicted differences in life expectancy,while changes in wealth barely mattered Lutz argues that because schooling happens many years before a person has attained their life expectancy,this correlation reflects cause:better education drives longer life.It also tends to lead to more wealh,which is why wealth and longevity are also correlated.But what is important,says Lutz,is that wealth does not seem to be driving longevity,as experts thought-in fact,education is driving both of them Lifestyle choices Some medical professionals may not like these findings,"says Lutz,as they suggest schools may be a better health investment than high-tech hospitals.But RudigerKrech at the World Health Organization welcomes the study."It confirms education as a major social determinant of health,"he says-aconcept WHO actively promotes.But if medical health experts welcome the findings,economists are less comfortable Sangheon Lee,at the UN International Labour Organisation in Geneva,Switzerland agrees education affects lifespan but doubts that simple models like Lutz's can fully resolve cause and effect."It's a very difficult econometric problem,"he says,with health,wealth and education all affecting each other But Lutz says that extreme examples are telling.Cuba is dead poor but has a higher life expectancy than the US because it is well educated.Meanwhile in oil-rich but poorly-educated Equatorial Guinea,people rarely reach 60What does the word"plot"（Line 1,Para.2）mean?A.To make a secret plan to harm somebodyB.To make a diagram that shows how things developC.To suggest something as a plan or course of actionD.To mark the path of an aircraft or ship on a map

Text 3 The relationship between formal education and economic growth in poor countries is widely misunderstood by economists and politicians alike.Progress in both area is undoubtedly necessary for the social,political and intellectual development of these and all other societies;however,the conventional view that education should be one of the very highest priorities for promoting rapid economic development in poor countries is wrong.We are fortunate that is it,because building new educational systems there and putting enough people through them to improve economic performance would require two or three generations.The findings of a research institution have consistently shown that workers in all countries can be trained on the job to achieve radically higher productivity and,as a result,radically higher standards of living.Ironically,the first evidence for this idea appeared in the United States.Not long ago,with the country entering a recessing and Japan at its pre-bubble peak.The U.S.workforce was derided as poorly educated and one of the primary cause of the poor U.S.economic performance.Japan was,and remains,the global leader in automotive-assembly productivity.Yet the research revealed that the U.S.factories of Honda,Nissan,and Toyota achieved about 95 percent of the productivity of their Japanese counterparts--a result of the training that U.S.workers received on the job.More recently,while examining housing construction,the researchers discovered that illiterate,non-English-speaking Mexican workers in Houston,Texas,consistently met best-practice labor productivity standards despite the complexity of the building industry's work.What is the real relationship between education and economic development?We have to suspect that continuing economic growth promotes the development of education even when governments don't force it.After all,that's how education got started.When our ancestors were hunters and gatherers 10,000 years ago,they didn't have time to wonder much about anything besides finding food.Only when humanity began to get its food in a more productive way was there time for other things.As education improved,humanity's productivity potential increased as well.When the competitive environment pushed our ancestors to achieve that potential,they could in turn afford more education.This increasingly high level of education is probably a necessary,but not a sufficient,condition for the complex political systems required by advanced economic performance.Thus poor countries might not be able to escape their poverty traps without political changes that may be possible only with broader formal education.A lack of formal education,however,doesn't constrain the ability of the developing world's workforce to substantially improve productivity for the foreseeable future.On the contrary,constraints on improving productivity explain why education isn't developing more quickly there than it is.34.The author quotes the example of our ancestors to show that education emerged__________.A.when people had enough timeB.prior to better ways of finding foodC.when people on longer went hungD.as a result of pressure on government

根据下面资料，回答Today, people all over the world are moving out of small villages in the country to go and live in big, noisy cities. They are moving from the peaceful hills, mountains, fields, rivers and streams of the countryside to the busy world of streets, buildings, traffic and crowds. This movement from rural areas to urban areas has been going on for over two hundred years. In many countries, the main reason why people come to live in towns and cities is work. After one or two large factories have been built in or near a town, people come to find work, and soon an industrial area begins to grow. There is usually a residential area nearby, where the factory workers can live. The families of these workers need schools, hospitals and shops, so more people come to live in the area to provide these services and a city grows. In every major city in the world, there is a business district where the big companies have their main offices. In the United States, this area is usually in the city centre. It is here that you can see the huge skyscraper office blocks. The people who work here often travel a long way to work each day. Many of them live in the suburbs of the city, far away from the industrial area and the city centre. Some suburbs are very pleasant, with nice houses and big gardens. There are usually parks for children to play in and large department stores where you can buy all you need. But what is the future of the big cities? Will they continue to get bigger? Perhaps not. Some major cities have actually become smaller in the last ten years, and it is quite possible that one day we will see people moving out of the major cities and back into smaller towns and villages. Why do people move to live in cities or towns?A.Because they can live more comfortably there.B.Because they prefer a noisy life to a peaceful life.C.Because they want to find work.D.Because they are sure of having a better life there.

When the number of products sold increases,people say the country is making progress.King Wangchuck had a different idea for Bhutan.He wanted to measure his country's progress by people's happiness.If the people's happiness increased,the king could say that Bhutan was making progress.To decide if people were happier,he created a measure called Gross National Happiness(GNH).GNH is based on certain principles that create happiness.People are happier if they have health care,education,and jobs.They are happier when they live in a healthy,protected environment.They are happier when they can keep their traditional culture and customs.Finally,people are happier when they have agood,stable government.Now there is some evidence of increased GNH in Bhutan.People are healthier and are living longer.

Text 4 When you go to bed,is it because you're tured or because you need to get up at a certain time and want to make sure you get enough sleep?Everyone has a chronotype,which is the sleep cycle that their body would naturally prefer,if left to its own devices.But society forces its own chronotype on people,too.Maybe your prefer to sleep from 2 a.m.t0 10 a.m.But if you have a typical 9-to-5 workday,to get eight hours,you'd probably need to sleep from something like 11 p.m.t0 7 a,m.Individuals'sleep is surely shaped by their jobs,their families,and their habits.But a new study shows that society can shape sleep broadly,on a population level,as well.In the paper,published in Science Advances,Olivia Walch,Amy Cochran,and Daniel Forger of the University of Michigan look at data gathered from a smartphone app to see how sleep cycles vary in different countries and among different demographics.What country people lived in didn't have any noticeable effect on when they woke up,but it was linked to what time they went to bed.And what time they went to bed was linked to how much sleep they got.So in the countries that got less sleep on average,like Japan and Brazil,it was because they were going to bed later,not because they were waking up earlier than people in countries that got more sleep on average,like the Netherlands and Belgium,where people have earlier bedtimes.But it's notable in pointing out bedtime as a problem area.A lot of the research and discussion about the tension between sleep and society has focused on the morning-how the 9-to-5 workday isn't suitable for everyone's internal clocks,how starting the school day later can help teens,who have notoriously late chronotypes,how exposing yourself to light in the moming can help keep your intemal clock wound in a way that promotes good sleep.Bedtime,meanwhile,seems like it should be more of a choice.You wake up to go somewhere,or to start fulfilling responsibilities,and you go to bed when you decide to,based on a complex calculus of how tired you are,how much sleep you want to get,and whether the chapter you were just reading in your book ended on a cliffhanger.But when people are deciding to go to bed differs significantly across societies,it seems there's something cultural at play here,too.The paper published by the professors from University ofMichigan shows that____A.many people use smartphones before going to sleepB.the countries where people live may decide when they get upC.Japanese go to bed later and wake up laterD.people in some European countries enjoy longer sleep time
