When we talk about Americans barely into adulthood who are saddled with（担负着） unbearable levels of debt' the conversation is almost always about student loan debt． But there's a growing body of evidence suggesting that today's young adults are also drowning in credit-card debt and that many of them will take this debt to their graves（坟墓）． More than 20% overspent their income by more than ﹩100 every single month． Since they haven't built up their credit histories yet， it's a safe bet that these young adults are paying relatively high interest rates on the resulting credit card debt． Although many young people blame "socializing" as a barrier to saving money， most of them aren't purchasing ﹩20 drinks in trendy bars． They're struggling with much more daily financial demands． To a disturbingly large extent， the young and the broke are relying on credit cards to make it until their next payday． This obviously isn't permanent in the long run， and it's going to put a huge drag on their spending power even after they reach their peak earning years， because they'll still be paying interest on that bottle of orange juice or box of spaghetti （意式面条）they bought a decade earlier． A new study out of Ohio State University found that young adults are accumulating credit card debt at a more rapid rate than other age groups， and that they're slower at paying it off． "If what we found continues to hold true， we may have more elderly people with substantial financial problems in the future'" warns Lucia Dunn， professor of economics at Ohio State． "If our findings persist， we may be faced with a financial crisis among elderly people who can't pay off their credit cards．" Dunn says a lot of these young people are never going to get out from under their credit card debt． "Many people are borrowing on credit cards so heavily that payoff rates at these levels are not plenty to recover their credit card debt by the end of their life which could have loss impacts for the credit card issuing banks，"（1）What is the main idea of the first paragraph？ ____ A． Many young Americans will never be able to pay off their debts．B． Credit cards play an increasingly important role in college life．C． Credit cards are doing more harm than student loans．D． The American credit card system is under criticism．（2）Why do young people have to pay a higher interest on their credit card debt？ ____ A． They tend to forget about the deadlines．B． They haven't developed a credit history．C． They are often unable to pay back in time．D． They are inexperienced in managing money．（3）What is said to be the consequence of young adults relying on credit cards to make ends meet？ ____ A． It will place an unnecessary burden on society．B． It will give them no motivation to work hard．C． It will exert psychological pressure on them．D． It will affect their future spending power．（4）What will happen to young adults if their credit card debt keeps accumulating according to Lucia Dunn？ ____ A． They will have to pay an increasingly higher interest rate．B． They may experience a financial crisis in their old age．C． Their quality of life will be affected．D． Their credit cards may be cancelled．（5）What does Lucia Dunn think might be a risk for the credit card issuing banks？ ____ A． They go bankrupt as a result of over-lending．B． They lose large numbers of their regular clients．C． Their clients leave their debts unpaid upon death．D． Their interest rates have to be reduced now and then．

Directions: 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 1 to 5 are based on the following passage. A growing number of U. S. bike riders are attracted to electric bikes for convenience, health benefits and their fun factor. Although ebikes first appeared in the 90s，cheaper options and longer- lasting batteries are breathing new life into the concept. Established bike companies and startups are embracing ebikes to meet demand. About 34 million ebikes were sold worldwide last year, according to data from eCycleElectric Consultants. Most were sold in Europe and China, where the bikes already have exploded in popularity. Recently, the U. S. market has grown to 263 ,000 bikes, a 25% gain from the prior year. The industry is benefiting from improved batteries as suppliers over the years developed technology for laptops, smartphones and electric cars. In 2004，the price of batteries used on ebikes fell, spurring European sales. But lower cost options are emerging, too. This month, three U. s. bikeshare companies, Motivate, LimeBike and Spin, announced electric bicycles will be added to their fleets. New York- based Jump Bikes is already operating an electric bikeshare in Washington, D. C.，and is launching in San Francisco Thursday. Rides cost 2 for 30 minutes. The system works like existing dockless bikeshare systems, where riders unlock bikes through a smartphone app. "This is the beginning of a long-term shift away from regular pedal (踏板)to electric bikes," said Jump Bikes CEO Ryan Rzepecki .“When people first jump on an ebike, their face lights up. It's exciting and joyful in a way that you don't get from a regular bike.” Two years ago, CEO Chris Cocalis of Pivot Cycles, which sells high-end mountain bikes, found that U. S. bike shops weren't interested in stocking ebikes. Some retailers warned Cocalis that they'd drop the brand if it came out with an electric bike. Now that sales are taking off, the vast majority of bike dealers are asking Cocalis when he lI make an ebike available. "There's tremendous opportunity to get a generation of people for whom suffering isn't their thing," Cocalis said.“Ebike riders get the enjoyable part of cycling without the massive suffering of climbing huge hills. ”1. What do we learn from the passage about ebikes?A.Their health benefits and fun values outweigh their cost.B.They did not catch public attention in the United States until the 1990s.C.They did not become popular until the emergence of improved batteries.D.Their widespread use is attributable to people s environmental awareness.2. What brought about the boost in ebike sales in Europe at the beginning of the century?A.Updated technology of bike manufacture.B.The falling prices of ebike batteries.C.Changed fashion in short-distance travel.D.The rising costs for making electric cars.3. What is the prospect of the bike industry according to Ryan Rzepecki?A.More will be invested in bike battery research.B.The sales of ebikes will increase.C.It will profit from ebike sharing.D.It will make a difference in people's daily lives.4. What prevented Chris Cocalis from developing ebikes sooner?A.Retailers' refusal to deal in ebikes.B.High profits from conventional bikes.C.Users' concern about risks of ebike riding.D.His focus on selling costly mountain bikes.5. What makes Chris Cocalis believe there is a greater opportunity for ebike sales?A.The further lowering of ebike prices.B.The public's concern for their health.C.The increasing interest in mountain climbing.D.The younger generation's pursuit of comfortable riding.

When we talk about Americans barely into adulthood who are burdened with unbearable levels of debt，the conversation is almost always about student loan debt.But there's a growing body of evidence suggesting that today's young adults are also drowning in credit-card debt—and that many of them will take this debt to their graves. More than 20% over spent their income by more than ﹩100 every single month.Since they haven't built up their credit histories yet，it's a safe bet that these young adults are paying relatively high interest rates on the resulting credit card debt. Although many young people blame "socializing" as a barrier to saving money，most of then aren't knocking back ﹩20 drinks in trendy （时尚的）lounges.They're struggling with much more daily financial demands. To a disturbingly large extent，the young and the broke are relying on credit cards to make it until their next pay day.This obviously isn't sustainable in the long run，and it's going to put a huge drag on their spending power even after they reach their peak earning years，because they'll still be paying interest on that bottle of orange juice or box of spaghetti they bought a decade earlier. A new study out of Ohio State University found that young adults are accumulating credit card debt at a more rapid rate than other age groups，and that they're slower at paying it off. "If what we found continues to hold true，we may have more elderly people with lots of financial problems in the future，" warns Lucia Dunn，professor of economics at Ohio State. "If our findings continue to exist，we may be faced with a financial crisis among elderly people who can't pay off their credit cards." Dunn says a lot of these young people are never going to get out from under their credit card debt. "Many people are borrowing on credit cards so heavily that payoff rates at these levels are not sufficient to recover their credit card debt by the end of their life，which could have loss implications for the credit card issuing banks.（1）What is the main idea of the first paragraph？ ____ A.Many young Americans will never be able to pay off their debts.B.Credit cards play an increasingly important role in college life.C.redit cards are doing more harm than student loans.D.The American credit card system is under criticism.（2）Why do young people have to pay a higher interest on their credit card debt？ ____ A.They tend to forget about the deadlines.B.They haven't developed a credit history.C.They are often unable to pay back in time.D.They are inexperienced in managing money.（3）What does Lucia Dunn think might be a risk for the credit card issuing banks？ ____ A.They go bankrupt as a result of over-lending.B.They lose large numbers of their regular clients.C.Their clients leave their debts unpaid upon death.D.Their interest rates have to be reduced now and then.

({B)} Genetically Modified Foods -- Feed the World ({/B)} If you want to spark a heated debate at a dinner party, bring up the topic about genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature. In fact, genetically modified foods are already yew much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle. Yet there are clearly some very real issues that, need to be resolved, lake any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy count, des, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from -- and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks The statistics on population growth and hunger are disturbing. Last year the world’s population reached 6 billion. And by 2050, the UN estimates, it will be probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the world’s available cultivable land per person is declining. Arable land has declined steadily since 1960 and will decrease by half over the next 50 years, according to the International Service for the Acquisition of Agri-Biotech Applications (ISAAA).({B)}How can biotech help ({/B)} Biotechnologists have developed genetically modified rice that is fortified with beta-carotene(β-胡萝卜素)―which the body converts into vitamin A -- and additional iron, mid they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attribution to pests, drought, poor soil and crop viruses, bacteria or fungi (真菌). Damage caused by pests is incredible. The European corn borer, for example, destroys 40 million tons of the world’s corn crops annual]y, about 7% of the total. Incorporating pest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa, yields have increased significantly. So far, fears that genetically modified, pest-resistant crops might kill good insects as well as bad appear unfounded. Viruses often cause massive failure in staple crops in developing countries. Two years ago, Africa lost more than half its cassava(树薯) crop --- a key source of calories -- to the mosaic virus. Genetically modified, virus-resistant crops can reduce that damage, as can drought-tolerant seeds in regions where water shortages limit the amount of land under cultivation. Biotech can also help solve the problem of soil that contains excess aluminum, which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity(毒性) in rice has been identified. Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and help prevent the loss of those crops after they are harvested. Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause of hunger. Poverty plays the largest role. Today more than I billion people around the globe live on less than I dollar a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to grow them or if the local population cannot afford to buy the food those farmers produce. Biotech has its own "distribution" problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products won’t even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companies are responding to needs of poor countries. More and more biotech research is being carried out in developing countries. But to increase the impact of genetic research on tile food production of those countries, there is a need for better collaboration between government agencies -- both local and in developed countries -- and private biotech firms. The ISAAA, for example, is successfully partnering with the US Agency for International Development, local researches and private biotech companies to find and deliver biotech solutions for farmers in developing countries.({B)}Will "Franken-foods" feed the world ({/B)} Biotech is not a panacea(治百病的药), but it does promise to transform agriculture in many developing countries. If that promise is not fulfilled, the real losers will be their people, who could suffer for years to come. The world seems increasingly to have been divided into those who favor genetically modified (GM) foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering -- which can induce plants to grow in poor soils or to produce more nutritious foods -- will soon become an essential tool for helping to feed the world’s burgeoning(迅速发展的) population. Skeptics contend that genetically modified crops could pose unique risks to the environment and to health -- risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of genetically modified agricultural products. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards Two years ago in Edinburgh, Scotland, eco-vandals stormed a field, crushing canola plants. Last year in Maine, midnight raiders hacked down more than 3,000 experimental poplar trees. And in San Diego, protesters smashed sorghum and sprayed paint over greenhouse walls. This far-flung outrage took aim at genetically modified crops. But the protests backfired: all the destroyed plants were conventionally bred. In each case, activists mistook ordinary plants for genetically modified varieties. It’s easy to understand why. In a way, genetically modified crops -- now on some 109 million acres of farmland worldwide -- are invisible. You can’t see, taste or touch a gene inserted into a plant or sense its effects on the environment. You can’t tell, just by looking, whether pollen containing a foreign gene can poison butterflies or fertilize plants miles away. That invisibility is precisely what worries people. How, exactly, will genetically modified crops affect the environment -- and when will we notice Advocates of genetically modified or transgenic crops say the plants will benefit the environment by requiring fewer toxic pesticides than conventional crops. But critics fear the potential risks and wonder how big the benefits really are. "We have so many questions about these plants," remarks Guenther Stotzky, a soil microbiologist at New York University. "There’s a lot we don’t know and need to find out." As genetically modified crops multiply in the landscape, unprecedented numbers of researchers have started fanning into the fields to get the missing information. Some of their recent findings are reassuring; others suggest a need for vigilance.Majority of people in those countries maintaining a long history of agriculture believe ______. A．genetically modified crop is beneficialB．genetically modified crop causes environmental problemsC．high-tech crop is a great benefit to the worldD．genetically modified foods is a heated topic

Since they haven’t built up their credit histories yet, it’s a safe bet that these young adults are paying relatively high interest rates on the resulting credit card debt.Although many young people blame “socializing” as a barrier to saving money, most of them aren’t knocking back ＄20 drinks in trendy (时尚的) lounges. They’re struggling with much more daily financial demands.To a disturbingly large extent, the young and the broke are relying on credit cards to make it until their next payday. This obviously isn’t sustainable in the long run, and it’s going to put a huge drag on their spending power even after they reach their peak earning years, because they’ll still be paying interest on that bottle of orange juice or box of spaghetti (意式面条) they bought a decade earlier.A new study out of Ohio State University found that young adults are accumulating credit card debt at a more rapid rate than other age groups, and that they’re slower at paying it off. “If what we found continues to hold true, we may have more elderly people with substantial financial problems in the future,” warns Lucia Dunn, professor of economics at Ohio State. “If our findings persist, we may be faced with a financial crisis among elderly people who can’t pay off their credit cards.”Dunn says a lot of these young people are never going to get out from under their credit card debt. “Many people are borrowing on credit cards so heavily that payoff rates at these levels are not sufficient to recover their credit card debt by the end of their life, which could have loss implications for the credit card issuing banks.”What is the main idea of the first paragraph A．Many young Americans will never be able to pay off their debts.B．Credit cards play an increasingly important role in college life.C．Credit cards are doing more harm than student loans.D．The American credit card system is under criticism.
