This kind of savi ngs program is called a prepaid tuiti on pla n. The money goes into an acco untThere is progress toward a possible treatment for lung diseases such as SARS (severe acute respiratory syndrome). Researchers have learned more about how the SARS virus works: it 47 with a system in the body that uses enzymes (酶)to control blood pressure and fluid balanee. Scientists say the virus 48 to an enzyme known as ACE-two. The virus blocks the enzyme, permitting fluid to enter the lungs.A team from Europe and Asia reported the 49 in Nature Medicine. Doctor Josef Penninger of the In stitute of Molecular Biotech no logy in the Austria n Academy of Scien ces was the 50 writer of the report.

Farmers have their own way to 47 marginal land: It is the last to be pla nted un der good con diti ons, and has the 48_to be avoided un der poor con diti ons. Low 49 soil is not the only reas on land could be con sidered margin al. It might be in an area where rain fall is 50—or where a hillside might rise too steeply.There are uses for margin al la nd, however. Most often it is used as grassla nd. Grasses provide excelle nt 51一for grazing (吃草)animals like cattle, sheep and goats. Grass seed can be bought from a foreign supplier or52_grasses can be used. However, using marginal land for grazing is not a simple issue. There is a 53 of overgrazing. Cattle can damage the crops by eating down to the roots. Also, the weight of the animals crushes the soil and can make it too hard for grow ing. A( n) 54 way to reduce the harm is to move an imals from one field to another. This method is known as rotational grazing (循环放牧)which is extremely important for marginal Ian d.Ano ther use for margin al la nd is for tree crops. Studies have 55 that the white pine and loblolly pine (火炬松)are two kinds of trees that grow well on such land. They grow fast and provide good quality wood. Another tree is the poplar (白杨),found in many parts of the world.Failure to take the care needed to protect marginal lands can make a bad situation worse. But goodChina is casti ng such a huge shadow on the Un ited States that many America ns are trying hard to lear n the Chin ese Ian guage with an effort to keep their competitive edge."Interest in learning Chinese among American youth and their parents has grown 47 in the past five years," said Vivie n Stewart, vice preside nt at the Asia Society, a US group trying to bridge the 48 betwee n America ns and the peoples of Asia and the Pacific.China's rapid progress is driving the interest to 49 the Ianguage, experts say.

It has 54 the Un ited States as the world's largest con sumer and could become the sec ond largest economy in the world, in the n ext two to three decades.Even though the US State Departme nt has regarded the Chin ese Ian guage extremely importa nt to n ati onal prosperity , the" 55 c on diti ons to support recruitme nt of stude nts and teachers as well as the growth of high quality programs is 56 in adequate," an Asia Society study says.Can money buy happ in ess? Yes, 47 the authors of a new study---but only to a point.Psychology has show n that richer people gen erally rank the overall quality of their lives more 48 tha n poorer people do. At the same time, their actual happ in ess seems to be 49 less by their ability to buy more tha n by being able to keep up with those with comparable resources in their own age group."Our findings point to the possibility that, rather tha n promoti ng overall happ in ess, con ti nued in come growth could —50—an ongoing consumption race where people have to consume more and more, just to mai nta in a 51 level of happ in ess," writes Gle nn Firebaugh of Penn sylva nia State Un iversity.The study was 52 at the America n Sociological Associati on's 100th Annual Meeti ng. Whether the rich are happier as a whole tha n their less 53 fellows is beco ming an in creas in gly hot topic for debate. Rece nt years have 54 ma ny writi ngs on the "scie nee of happ in ess." Richer people are happier because money can help purchase goods and services and it is the —55—of these materials that in creases on e's enjoyme nt of life and on e's sense of well-bei ng. Firebaugh and his colleagues measured the age, total family in come, and generalhapp in ess of —56 _ aged 20 to 64, gen erally con sidered the work ing lifespa n ( 工作寿命)for most America ns.Regardless of such standards as physical health, education, and marital status (婚姻状况),people's happ in ess was affected by what others earn ed.

大学英语四级_选词填空单项训练+答案

Directions: In this section, there is a passage with ten blanks. You are requested to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 47 to 56 are based on the following passage.（1）Once the world embraced the automobile, the days of depending on horses, bicycles, ferries, and trains quickly slipped into the past. People were __47__ with the speed of the automobile but they were also enjoying the personal freedom that the automobile gave them. Owning a car gave people the freedom to go anyplace a road __48__. This allowed people to and at their own __49__. This independence gave the car a popular edge over buses and trains. The popularity of the automobile made it the __50__ of the transportation system. The automobile changed our lives when it created a giant industry that offered more and more jobs. The automobile made it possible for people to live in areas __51__ from their work place. This caused cities to grow and made suburban living more convenient. Of course, with more places to go, more __52__ roads had to be built. The automobile caused a __53__ effect. Jobs increased, industries grew, new industries developed, and cities appeared. Today the automobile industry continues to offer many __54__. Jobs are plentiful in this industry and improvements continue to be made to the automobile with new technologies.We have come a long way from that first __55__ carriage because of the cooperative efforts of many people in the last century. It will be interesting to see what the future holds for the automobile. We have already seen signs of the use of solar energy in this area. As long as man has a brain, the future of the automobile is __56__.（2）A college education is an investment in the future. But it can be a 47 one. The College Board 48 that the costs at a four-year public college in the United States increased 10% this past school year. That was less than the 13% increase the year before, but still much higher than the inflation 49 Public colleges and universities still cost a lot less than private ones.Financial aid often helps. But financial experts 50 parents to start college savings plans when their child is Still very young.All fifty states and the District of Columbia 51 what are called 5-29 plans. These plans are named after the part of the federal tax law that created them in 1996. States use private investment companies to operate the 52 of the programs.Every state has its own rules 53 5-29 plans. Some of the plans are 54 of state taxes. And all are not required to pay federal taxes. However, the government could start to tax withdrawals in 2011 if Congress does not change the law.5-29 plans include investment accounts that increase or decrease in value with the investments they contain. Families must decide how 55 they want to put money into stocks, or other investments.Another kind of 5-29 plan lets parents begin to pay for their child’s education in 56 and long before theirchild starts college. This kind of savings program is called a prepaid tuition plan. The money goes into an accountThere is progress toward a possible treatment for lung diseases such as SARS (severe acute respiratory syndrome). Researchers have learned more about how the SARS virus works: it 47 with a system in the body that uses enzymes (酶) to control blood pressure and fluid balance. Scientists say the virus 48 to an enzyme known as ACE-two. The virus blocks the enzyme, permitting fluid to enter the lungs.A team from Europe and Asia reported the 49 in Nature Medicine. Doctor Josef Penninger of the Institute of Molecular Biotechnology in the Austrian Academy of Sciences was the 50 writer of the report. The discovery could lead to a new 51 of treating not just SARS but also other diseases that can cause lung failure. These include avian flu (禽流感) and influenza in humans.The first 52 of SARS were discovered in Guangdong province, in southern China, in November of 2002. SARS was not 53 as a worldwide threat until March of 2003. The disease spread to 26 countries, most of them in the Asia-Pacific area. An estimated 8, 000 people had SARS. More than 770 of them died, or about 10% , a 54 high rate.The World Health Organization warned people not to travel to 55 areas. The 56 hurt international travel and business. The WHO says the disease stopped spreading by July of 2003. As a result of SARS, the health agency got new powers to act before a government officially announces a crisis.（4）To call something “marginal” means it is not very good. Farmers have their own way to 47 marginal land: It is the last to be planted under good conditions, and has the 48 to be avoided under poor conditions. Low 49 soil is not the only reason land could be considered marginal. It might be in an area where rainfall is 50 or where a hillside might rise too steeply.There are uses for marginal land, however. Most often it is used as grassland. Grasses provide excellent51 for grazing (吃草) animals like cattle, sheep and goats. Grass seed can be bought from a foreign supplier or52 grasses can be used. However, using marginal land for grazing is not a simple issue. There is a 53 of overgrazing. Cattle can damage the crops by eating down to the roots. Also, the weight of the animals crushes the soil and can make it too hard for growing. A(n) 54 way to reduce the harm is to move animals from one field to another. This method is known as rotational grazing (循环放牧) which is extremely important for marginal land.Another use for marginal land is for tree crops. Studies have 55 that the white pine and loblolly pine (火炬松) are two kinds of trees that grow well on such land. They grow fast and provide good quality wood. Another tree is the poplar (白杨), found in many parts of the world.Failure to take the care needed to protect marginal lands can make a bad situation worse. But goodChina is casting such a huge shadow on the United States that many Americans are trying hard to learn the Chinese language with an effort to keep their competitive edge."Interest in learning Chinese among American youth and their parents has grown 47 in the past five years," said Vivien Stewart, vice president at the Asia Society, a US group trying to bridge the 48 between Americans and the peoples of Asia and the Pacific.China's rapid progress is driving the interest to 49 the language, experts say. "The Chinese rich cultural traditions and 50 economy mean that it is now essential for all of our students to be better prepared to engage them and seize opportunities together," said Michael Levine, Asia Society' s executive director of education.A 2004 College Board survey found that 2,400 high schools--an 51 number--would be interested in52 the Advanced Placement (AP) courses in Chinese language and culture when the courses become available in 2006.China, the world' s most populous ( 人口稠密的) nation, is 53 to the United States because it is a leading trader, consumer and investor. It has 54 the United States as the world's largest consumer and could become the second largest economy in the world, in the next two to three decades.Even though the US State Department has regarded the Chinese language extremely important to national prosperity , the" 55 conditions to support recruitment of students and teachers as well as the growth of high（6）Can money buy happiness? Yes, 47 the authors of a new study---but only to a point.Psychology has shown that richer people generally rank the overall quality of their lives more 48 than poorer people do. At the same time, their actual happiness seems to be 49 less by their ability to buy more than by being able to keep up with those with comparable resources in their own age group."Our findings point to the possibility that, rather than promoting overall happiness, continued income growth could 50 an ongoing consumption race where people have to consume more and more, just to maintain a 51 level of happiness," writes Glenn Firebaugh of Pennsylvania State University.The study was 52 at the American Sociological Association's 100th Annual Meeting. Whether the rich are happier as a whole than their less 53 fellows is becoming an increasingly hot topic for debate. Recent years have 54 many writings on the "science of happiness." Richer people are happier because money can help purchase goods and services and it is the 55 of these materials that increases one's enjoyment of life and one's sense of well-being. Firebaugh and his colleagues measured the age, total family income, and general happiness of 56 aged 20 to 64, generally considered the working lifespan (工作寿命) for most Americans.Regardless of such standards as physical health, education, and marital status (婚姻状况), people's happiness was affected by what others earned. The higher the income of others in one's age group, the lower one'sKitchen duties may have traditionally been viewed as women’s work, but not at the White House. Until now: Cristeta Comerford has been named executive chef (厨师) .After an_ 47 six-month search, first lady Laura Bush announced Sunday that Comerford was chosen from hundreds of 48 to head the executive kitchen. A naturalized U.S. citizen from the Philippines, she will be the first woman and first 49 to hold the post. The 42-year-old Comerford has been an assistant chef at the White House for 10 years. She worked under former executive chef Walter Scheib Ill, who 50 in February.Scheib said Sunday that Comerford was 51 the best assistant he had in his 30-year career and is a wonderful choice to take over. He said she is a great cook with an artistic eye and a calm manner that can 52 the pressure cooker (高压锅) in the White House kitchen.Comerford has a bachelor’s degree in Food Technology from the University of the Philippines. She has worked at Le Ciel in Vienna, Austria and at restaurants in two Washington hotels.While being executive chef at the White House is honorable, the job also can be 53 Comerford will be in charge of everything from state dinners for world leaders to dessert for the commander in chief, his family and guests. The head chef is 54 for designing and executing menus for state dinners, social events, holiday functions, receptions and official luncheons (午宴) 55 by the president and first lady. The job pays 56The more time children spend watching television the poorer they perform academically, according to three studies published on Monday. 47 television viewing has been blamed for increasing rates of childhood obesity (肥胖) and for aggressive behavior, while its 48 on schooling have been inconclusive, researchers said.But studies published on the topic in this month' s Archives of Pediatrics (小儿科) & Adolescent Medicine concluded television viewing 49 to have an adverse effect (副作用) on academic pursuits. For 50 , children who had televisions in their bedrooms--and 51 watched more TV--scored lower on standardized tests than those who did not have sets in their rooms.

大学生英语四级考试答案（完整版）〔作文〕第一套：Directions: For this part you are allowed 30 minuites to write an essay on whether technology will make people lay. You should write at least 120 words but no more than 180 words. Addited to technologyNowadays, there has been a heated discussion over whether people are becoming addicted to technology. Views on the topic vary greatly among people from different walks of life. Some believe that technology is part of our life, but others are concerned that we are too dependent on technology.I agree with the former, and there are two major reasons. Firstly, it is undeniable that people can’t live without technology in the modern society. Things such as our mobile phones, computers, transportation systems are all products of technological development. Secondly, we used to eat at home or restaurants daily, but now online food ordering has become prevalent, especially among fulltime workers. The new way of life has brought us much convenience, which is obviously proved during the pandemic in this year.From my perspective, it is crucial that our society should encourage people to embrace the convenience brought byadvanced technologies and use technology in a rational way. Only by doing so can we achieve greater success.作文其次套：Directions: For this part you are allowed 30 minuites to write an essay on Do Violent Games Cause Student Violence. You should write at least 120 words but no more than 180 words. violence in video gamesNowadays, there has been a heated debate over whether violence depicted in video games can trigger realworld violence. Views on the topic vary greatly. Some believe that video games are harmless, but others are concerned that it might lead to violent behaviors among youngsters.I agree with the latter, and there are two major reasons. Firstly, unlike TV or books, video games are more interactive, thus those who play video games are more likely to be fully engaged, so they probably are unable to tell the difference between the virtual world and the reality. Secondly, children are not as selfdisciplined as adults, video games with violence contents can have negative effects on their developing minds. It is possible that they get aggressive in real life.From my perspective, it is crucial that the government should regulate the production and sale of violent video games.What’s more, parents should play an active role in creating a healthy environment for their children. Only by doing so can we ensure the healthy development of children.听力第一套：1.B) Send him to an afterschool art class.2.A) Contacted Joe to decorate its diningroom.3.A) Get her pet dog back.4.D) It is offering a big reward to anyone who helps.5.B) Help people connect with each other.6.C) It does not use volunteers7.D)They will find they have something in common8.C) Preparations for Saturdays gettogether.9.B) It enables guests to walk around and chat freely.10.A) It offers some big discounts.11.D)Bring his computerand speakers12.D) For convenience at weekends.13.A) They are reliable.14.C) Seek advice from his friend15.B)He can be trusted.16.A) Many escaped from farms and became wild.17.D)They carry a great many diseases.18.C) They fell victim to eagles.19.B) Roast coffee beans in outer space.20.A) They can easily get burned.21.C) They collaborated on building the first space coffee machine.22.B)A race passes through it annually.23.C)It’s tasty fruit pies.24.B) The entire village.25.D) She helped the village to become famous.选词填空第一套:Most animas seek shade when temperatures in the Sahara Desert soar26.C) crawling27.F)hunt28.E) extreme29.K) species30.G) literally31.M) thick32.J) removed33.N)tiny34.0) unique35.A)adaptings.选词填空其次套:Social isolation poses more health risks than obesity...26.1) implication27.B) appointments A pass一天“29.0) touches28.D) debating30.C) consequences31.L) sparked32.F) friendly33.J) pushing34.N) survey35.K) severely选词填空第三套:Nowadays you cant buy anyhing without then being asked to provide...26.E) experience27.

More than 770 of them died, or about 10% , a 54 high rate.The World Health Organization warned people not to travel to 55 areas. The 56 hurt international travel and business. The WHO says the disease stopped spreading by July of 2003. As a result of SARS, the health（4）To call something “marginal” means it is not very good. Farmers have their own way to 47 marginal land: It is the last to be planted under good conditions, and has the 48 to be avoided under poor conditions. Low 49 soil is not the only reason land could be considered marginal. It might be in an area where rainfall is 50 or where a hillside might rise too steeply.There are uses for marginal land, however. Most often it is used as grassland. Grasses provide excellent51 for grazing (吃草) animals like cattle, sheep and goats. Grass seed can be bought from a foreign supplier or52 grasses can be used. However, using marginal land for grazing is not a simple issue. There is a 53 of overgrazing. Cattle can damage the crops by eating down to the roots. Also, the weight of the animals crushes the soil and can make it too hard for growing. A(n) 54 way to reduce the harm is to move animals from one field to another. This method is known as rotational grazing (循环放牧) which is extremely important for marginal land.Another use for marginal land is for tree crops. Studies have 55 that the white pine and loblolly pine (火炬松) are two kinds of trees that grow well on such land. They grow fast and provide good quality wood. Another tree is the poplar (白杨), found in many parts of the world.Failure to take the care needed to protect marginal lands can make a bad situation worse. But goodChina is casting such a huge shadow on the United States that many Americans are trying hard to learn the Chinese language with an effort to keep their competitive edge."Interest in learning Chinese among American youth and their parents has grown 47 in the past five years," said Vivien Stewart, vice president at the Asia Society, a US group trying to bridge the 48 between Americans and the peoples of Asia and the Pacific.China's rapid progress is driving the interest to 49 the language, experts say. "The Chinese rich cultural traditions and 50 economy mean that it is now essential for all of our students to be better prepared to engage them and seize opportunities together," said Michael Levine, Asia Society' s executive director of education.A 2004 College Board survey found that 2,400 high schools--an 51 number--would be interested in52 the Advanced Placement (AP) courses in Chinese language and culture when the courses become available in 2006.China, the world' s most populous ( 人口稠密的) nation, is 53 to the United States because it is a leading trader, consumer and investor. It has 54 the United States as the world's largest consumer and could become the second largest economy in the world, in the next two to three decades.Even though the US State Department has regarded the Chinese language extremely important to national prosperity , the" 55 conditions to support recruitment of students and teachers as well as the growth of high（6）Can money buy happiness? Yes, 47 the authors of a new study---but only to a point.Psychology has shown that richer people generally rank the overall quality of their lives more 48 than poorer people do. At the same time, their actual happiness seems to be 49 less by their ability to buy more than by being able to keep up with those with comparable resources in their own age group."Our findings point to the possibility that, rather than promoting overall happiness, continued income growth could 50 an ongoing consumption race where people have to consume more and more, just to maintain a 51 level of happiness," writes Glenn Firebaugh of Pennsylvania State University.The study was 52 at the American Sociological Association's 100th Annual Meeting. Whether the rich are happier as a whole than their less 53 fellows is becoming an increasingly hot topic for debate. Recent years have 54 many writings on the "science of happiness." Richer people are happier because money can help purchase goods and services and it is the 55 of these materials that increases one's enjoyment of life and one's sense of well-being. Firebaugh and his colleagues measured the age, total family income, and general happiness of 56 aged 20 to 64, generally considered the working lifespan (工作寿命) for mostAmericans.Regardless of such standards as physical health, education, and marital status (婚姻状况), people's happiness was affected by what others earned. The higher the income of others in one's age group, the lower one's（7）Kitchen duties may have traditionally been viewed as women’s w ork, but not at the White House. Until now: Cristeta Comerford has been named executive chef (厨师) .After an_ 47 six-month search, first lady Laura Bush announced Sunday that Comerford was chosen from hundreds of 48 to head the executive kitchen. A naturalized U.S. citizen from the Philippines, she will be the first woman and first 49 to hold the post. The 42-year-old Comerford has been an assistant chef at the White House for 10 years. She worked under former executive chef Walter Scheib Ill, who 50 in February.Scheib said Sunday that Comerford was 51 the best assistant he had in his 30-year career and is a wonderful choice to take over. He said she is a great cook with an artistic eye and a calm manner that can 52 the pressure cooker (高压锅) in the White House kitchen.Comerford has a bachelor’s degree in Food Technology from the University of the Philippines. She has worked at Le Ciel in Vienna, Austria and at restaurants in two Washington hotels.While being executive chef at the White House is honorable, the job also can be 53 Comerford will be in charge of everything from state dinners for world leaders to dessert for the commander in chief, his family and guests. The head chef is 54 for designing and executing menus for state dinners, social events, holiday functions, receptions and official luncheons (午宴) 55 by the president and first lady. The job pays 56（8）The more time children spend watching television the poorer they perform academically, according to three studies published on Monday. 47 television viewing has been blamed for increasing rates of childhood obesity (肥胖) and for aggressive behavior, while its 48 on schooling have been inconclusive, researchers said.But studies published on the topic in this month' s Archives of Pediatrics (小儿科) & Adolescent Medicine concluded television viewing 49 to have an adverse effect (副作用) on academic pursuits. For 50 , children who had televisions in their bedrooms--and 51 watched more TV--scored lower on standardized tests than those who did not have sets in their rooms. In contrast, the study found having a home computer with 52 to the Intemet resulted in comparatively higher test scores."Consistently, those with a bedroom television but no 53 home computer had, on average, the lowest scores and those with home computer but no bedroom television had the highest scores," wrote study author Dina Borzekowski of Johns Hopkins University. The American Academy of Pediatrics has 54 parents to limit children’s television viewing to no more than one to two hours per day--and to try to keep younger children away from TV altogether.In two other studies published in the same journal, children who 55 watched television before the age of 3 ended up with lower test scores later on, and children and adolescents who watched more television were less选词填空答案(1) 47-56 N E O A M L J I G B （2）47-56 G B E I C L N K A M（3）47-56 M C J G A E L I O D （4）47-56 F B J E A K N D L H（5）47-56 C K G A I N D F M O （6）47-56 C N E H A J B K F M（7）47-56 D K B I F H L A O E （8）47-56 J G M K D E B I C F（本资料素材和资料部分来自网络，仅供参考。
