Kate Lee and a group of colleagues found that (3)_______ anattention-demanding task with a 40-second microbreak in which one simply looks at a computerized (4)_______ of a green roof improved focus as well as subsequent performance on the task.In the research, 150 students were asked to perform a demanding task called the Sustained Attention to Response Task (SART). In the task, respondents view a (5)_______ of individual numbers, between 1 and 9, on a computer screen. Each number flashes by very (6)_______ and the research subject has to press a particular key as fast as possible unless, the number is 3. In that case, subjects have to catch themselves and not respond which is difficult to do, given the habit built up of repeatedly and quickly (7)_______ the key.In the current study, students had to (8)_______ the SART task not once, but twice. However, they received a 40-second microbreak in between the two trials. During that break, their computer screens flashed either to a digital image of a city building roof covered in (9)_______, or one covered with grass and flowers. Then, they completed the remainder of the SART trial.Afterward, the students (10)_______ to the green roof scene not only reported that it felt more restorative (恢复健康的), they performed better on the task.

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.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 their child 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.

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。

英语四级选词填空练习题及答案英语四级选词填空练习题及答案：There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the "R" Strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S" strain)has also been developed.The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.1.The study of the effects of salt on high blood pressure was carried out ______.a.as members of the same family tend to use similar amounts of saltb.to explore the long-term use of a sodium based substancec.because it was proven that salt caused high blood pressured.because of the availability of chemically pure salt and its derivatives2.The main difference between "S" and "R" rats is their ______.a.need for sodium 22b.rate of matingc.reaction to saltd.type of blood3.We can infer from the article that sodium 22 can de used to ______.a.control high blood pressureb.cure high blood pressure caused by saltc.tell the "S" rats from the "R" ratsd.determine what a sodium chloride metabolism is like4.The most beneficial results of the research might be ______.a.development of diets free of saltb.an early cure for high blood pressurec.control of genetic agents that cause high blood pressured.the early identification of potential high blood pressure victims5.Which of the statements best relates the main idea of this article?a.When salt is added rats and human beings react similarly.b.The near future will see a cure for high blood pressure.c.The medical field is desperately in need of research.d.A tendency toward high blood pressure may be a hereditary factor.答案：acddd英语四级选词填空练习题及答案：Directions: In this section, there is apassage with ten blanks.

You may not use any of the words in the bank more than once.An office tower on Miller Street in Manchester is completely covered in solar panels. They are used to create some of the energy used by the insurance company inside. When the tower was first 26 in 1962, it was covered with thin square stones. These small square stones became a problem for the building and continued to fall off the face for 40 years until a major renovation was 27 . During this renovation the building's owners, CIS, 28 the solar panel company,Solar century. They agreed to cover the entire building in solar panels. In 2004, the completed CIS tower became Europe's largest 29 of vertical solar panels. A vertical solar project on such a large 30 has never been repeated since.Covering a skyscraper with solar panels had never been done before, and the CIS tower was chosen as one of the "10 best green energy projects". For a long time after this renovation project, it was the tallest building in the United Kingdom, but it was 31 overtaken by the Mill bank Tower.Green buildings like this aren't 32 cost-efficient for the investor, but it does produce much less pollution than that caused by energy 33 through fossil fuels. As solar panels get 34 , the world is likely to see more skyscrapers covered in solar panels, collecting energy much like trees do. Imagine a world where building the tallest skyscraper wasn't a race of 35 , but rather one to collect the most solar energy.A)cheaper B) cleaner C) collection D) competed E) constructed F) consulted G)dimension H) discovered I) eventually J) height K) necessarily L) production M) range N)scale O) undertaken答案速查：26--30 E O F C N 31--35 I K L A J参考词汇：corresponding adj. 相当的，相应的; 一致的;solar panels solar panels太阳能板; 太阳能电池板（solar panel的复数）；insurance company 保险公司；square adj. 平方的; 正方形的; 直角的; 正直的; vt. 使成方形; 与…一致; vi. 一致; n. 广场; 正方形；fall off 减少; 跌落; 下降; 离开；renovation n. 革新; 修理; 恢复活力；entire 完全的，整个的；vertical adj. 垂直的，直立的;repeat vt. 重复; 复制; 背诵; n. 重复; 副本；skyscraper n. 摩天楼，超高层大楼；特别高的东西overtake overtake vt. 赶上; 压倒; 突然来袭; vi. 超车overtaken v. 赶上，压倒（overtake的过去分词）cost-efficient adj. 有成本效益的；合算的;investor n. 投资者；fossil fuels [能源] 化石燃料; [能源] 矿物燃料；consult vt. 查阅; 商量; 向…请教;dimension n. 方面;[数] 维；尺寸；次元；容积vt. 标出尺寸；range n. 范围; 幅度; 排; 山脉; vi. 平行，列为一行; 延伸scale n. 规模; 比例；on a large scale 大规模地；undertake vt. 承担，保证; 从事; 同意; 试图注：上述词汇绝大部分为高中曾经学过的词汇。

英语四级真题（附答案）01选词填空Something in the air tonight 南加州雾霾Since the 1940s, southern California has had a reputation for smog. Things are not as bad as they once were but, according to the American Lung Association, Los Angeles is still the worst city in the United States for levels of 26. pollutants. Gazing down on the city from the Getty Centre, an art museum in the Santa Monica Mountains, one would find the view of the Pacific Ocean blurred by the haze (霾). Nor is the state’s bad air 27. restricted to its south. Fresno, in the central valley, comes top of the list in America for year-round pollution. Residents’hearts and lungs are affected as a 28. consequence.All of which, combined with California’s reputation as the home of technological 29. innovation, makes the place ideal for developing and testing systems designed to monitor pollution in 30. detail. And that is just what Aclima, a new firm in San Francisco, has been doing over the past few months. It has been trying out monitoring that are 31. intended to yield minute-to-minute maps of 32. outdoor airpollution. Such stations will also be able to keep an eye on what is happening inside buildings, including offices.To this end, Aclima has been 33. collaborating with Google’s Street View system. Davida Herzl, Aclima’s boss, says they have revealed pollution highs on days when San Francisco’s transit workers went on strike and the city’s 34. inhabitants were forced to use their cars. Conversely, “cycle to work”days have done their job by 35. creating pollution lows.A）assisted I）inhabitantsB）collaborating J）innovationC）consequence K）intendedD）consumers L）outdoorE）creating M）pollutantsF）detail N）restrictedG）domestic O）sumH）frequently02仔细阅读第一套Passage one：green spaceQuestion 46 to 50 are based on the following passage.Living in an urban area with green spaces has a long-lasting positive impact on people's mental well-being, a study has suggested. UK researchers found moving to a green space had a sustained positive effect, unlike pay rises or promotions, which only provided a short-term boost. Co-author Mathew White, from the European Centre for Environment and Human Health at the University of Exeter, UK, explained that the study showed people living in greener urban areas were displaying fewer signs of depression or anxiety."There could be a number of reasons,”he said, “for example, people do many things to make themselves happier: they strive for promotion or pay rises, or they get married. But the trouble with all those things is that within six months to a year, people are back to their original baseline levels of well-being. So, these things are not sustainable; they don’t make us happy in the long term. We found that for some lottery（彩票）winners who had won more than £500,000 the positive effect was definitely there, but after six months to a year, they were back to the baseline."Dr. White said his team wanted to see whether living in greener urban areas had a lasting positive effect on people's sense of well-being or whether the effect also disappeared after a period of time. To do this, the team used data from the British Household Panel Survey compiled by the University of Essex.Explaining what the data revealed, he said: "What you see is that even after three years, mental health is still better, which is unlike many of the other things that we think will make us happy." He observed that people living in green spaces were less stressed, and less stressed people made more sensible decisions and communicated better.46. According to one study, what do green spaces do to people?A) Improve their work efficiency.B) Add to their sustained happiness.C) Help them build a positive attitude towards life.D) Lessen their concerns about material well-being.47. What does Dr. White say people usually do to make themselves happier?A) Earn more money.B) Gain fame and popularity.C) Settle in an urban area.D) Live in a green environment.48. What does Dr. White try to find out about living in a greener urban area?A) How it affects different people.B) How strong its effect is.C) How long its positive effect lasts.D) How it benefits physically49. What did Dr. White research reveal about people living in a green environment?A) Their stress was more apparent than real.B) Their decisions required less deliberation.C) Their memories were greatly strengthened.D) Their communication with others improved.50. According to Dr. White, what should the government do to build more green spaces in cities?A) Find financial support.B) Improve urban planning.C) Involve local residents in the effort.D) Raise public awareness of the issue.第一套Passage two：the Olympic class shipsYou probably know about the Titanic, but it was actually just one of three state-of-the art(最先进的) ocean ships back in the day. The Olympic class ships were built by the Harland & Wolff ship makers in Northern Ireland for the White Star Line company. The Olympic class included theOlympic,the Britannic and the Titanic. What you may not know is that the Titanic wasn’t even the flagship of this class.All in all, the Olympic class ships were marvels of sea engineering, but they seemed cursed to suffer disastrous fates.The Olympic launched first in 1910, followed by the Titanic in 1911, and lastly the Britannic in 1914. The ships had nine decks, and White Star Line decided to focus on making them the most luxurious ships on the water. Stretching 269.13 meters, the Olympic class ships were wonders of naval technology, and everyone thought that they would continue to be so for quite some time. However, all suffered terrible accidents on the open seas. The Olympic got wreaked before the Titanic did, but it was the only one to survive and maintain a successful career of 24 years. The Titanic was the first to sink after famously hitting a huge iceberg in 1912. Following this disaster, the Britannic hit a naval mine in 1916 and subsequently sank as well.Each ship was coal-powered by several boilers constantly kept running by exhausted crews below deck. Most recognizable of the ship designs are the ship’s smoke stacks, but the fourth stack was actually just artistic in nature and served no functional purpose. While two of these ships sank, they were all designed with doucle hulls（船体）believed to make them “unsinkable”, perhaps a mistaken idea that led to the Titanic’s and theBritannic’s tragic end.The Olympic suffered two crashes with other ships and went on to serve as a hospital ship and troop transport in World War I. Eventually, she was taken out of service od 1935, ending the era of the luxurious Olympic class ocean liners.51. What does the passage say about the three Olympic class ships?A) They performed marvellously on the sea.B) They could all break the ice in their way.C) They all experienced terrible misfortunes.D) They were models of modern engineering.52. What did White Star Line have in mind when it purchased the three ships?A) Their capacity of sailing across all waters.B) The utmost comfort passengers could enjoy.C) Their ability to survive disasters of any kind.D) The long voyages they were able to undertake.53. What is said about the fourth stack of the ships?A) It was a mere piece of decoration.B) It was the work of a famous artist.C) It was designed to let out extra smoke.D) It was easily identifiable from afar.54. What might have led to the tragic end of the Titanic and the Britannic?A) Their unscientific designs.B) Their captains' misjudgment.C) The assumption that they were built with the latest technology.D) The belief that they could never sink with a double-layer body.55. What happened to the ship Olympic in the end?A) She was used to carry troops.B) She was sunk in World WarⅠ.C) She was converted into a hospital ship.D) She was retired after her naval service.第二套Passage one：memory slipsQuestions 46 to 50 are based on the following passage.Losing your ability to think and remember is pretty scary. We know the risk of dementia （痴呆）increases with age. But if you have memory slips，you probably needn’t worry. There are pretty clear differences between signs of dementia and age-related memory loss.After age 50，it’s quite common to have trouble remembering the names of people，places and thing quickly，says Dr. Kirk Daffner of Brigham and Woman’s Hospital in Boston.The brain ages just like the rest of the body. Certain parts shrink，especially areas in the brain that are important to learning，memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.Forgetting the name of an actor in a favorite movie，for example，is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it，that’s far more concerning，Daffner says. When you forget entire experiences，he says，that’s “a red flag that something more serious may be involved.”Forgetting how to operate a familiar object like a microwave oven，or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrong.But even then，Daffner says，people shouldn’t panic. There are many things that can cause confusion and memory loss，including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications like antidepressants.You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory.And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive （认知的）reserve，Daffner says.“Read books，go to movies，take on new hobbies or activities that force one to think in novel ways，”he says. In other words，keep your brain busy and working. And also get physically active，because exercise is a known brain booster.46. Why does the author say that one needn’t be concerned about memory slips？A）Not all of them are symptoms of dementia.B）They occur only among certain groups of people.C）Not all of them are related to one’s age.D）They are quite common among fifty-year-olds.47. What happens as we become aged according to the passage？A）Our interaction skills deteriorate.B）Some parts of our brain stop functioning.C）Communication within our brain weakens.D）Our whole brain starts shrinking.48. Which memory-related symptom should people take seriously？A）Totally forgetting how to do one’s daily routines.B）Inability to recall details of one’s life experiences.C）Failure to remember the names of movies or actors.D）Occasionally confusing the addresses of one’s friends.49. What should people do when signs of serious memory loss show up？A）Check the brain’s cognitive reserve.B）Turn to a professional for assistance.C）Stop medications affecting memory.D）Exercise to improve their well-being.50. What is Dr Daffner’s advice for combating memory loss？A）Having regular physical and mental checkups.B）Taking medicine that helps boost one’s brain.C）Engaging in known memory repair activities.D）Staying active both physically and mentally.第二套Passage two：达尔文的信Questions 51 to 55 are based on the following passage.A letter written by Charles Darwin in 1875 has been returned to the Smithsonian Institution Archives（档案馆）by the FBI after being stolen twice.“We realized in the mid-1970s that it was missing,”says Effie Kapsalis, head of the Smithsonian Institution Archives. “It was noted as missing and likely taken by an intern, from what the FBI is telling us. Word got out that it was missing when someone asked to see the letter for research purposes,”and the intern put the letter back. “The intern likely took the letter again once nobody was watching it.”Decades passed. Finally the FBI received a tip that the stolen document was located very close to Washington, D.C. Their art crime team recovered the letter but were unable to press charges because the time of limitations had ended. The FBI worked closely with the Archives to determine that the letter was both authentic and definitely Smithsonian’s property.The letter was written by Darwin to thank an American geologist, Dr. Ferdinand Vandeveer Hayden, for sending him copies of his research into the geology of the region that would become Yellowstone National Park. The letter is in fairly good condition, in spite of being out of the care of trained museum staff for so long.“It was luckily in good shape,”says Kapsalis,“and we just have to do some minor things in order to be able to unfold it. It has some glue on it that has colored it slightly, but nothing that will prevent us from using it. After it is repaired, we will take digital photos of it and that will be available online. One of our goals is to get items of high research value or interest to the public online.”It would now be difficult for an intern, visitor or a thief to steal a document like this. “Archiving practices have changed greatly since the 1970s,”says Kapsalis. “and we keep our high value documents in a safe that I don’t even have access to.”51.What happened to Darwin’s letter in the 1970s?A. It was recovered by the FBI.B. It was stolen more than once.C. It was put in the archives for research purposes.D. It was purchased by the Smithsonian Archives.52. What did the FBI do after the recovery of the letter?A. They proved its authenticity.B. They kept it in a special safe.C. They arrested the suspect immediately.D. They pressed criminal charges in vain.53.What is Darwin’s letter about?A. The evolution of Yellowstone National Park.B. His cooperation with an American geologist.C. Some geological evidence supporting his theory.D. His acknowledgement of help from a professional.54. What will the Smithsonian Institution Archives do with the letter according to Kapsalis?A. Reserve it for research purposes only.B. Turn it into an object of high interest.C. Keep it a permanent secret.D. Make it available online.55.What has the past half century witnessed according to Kapsalis?A. Growing interest in rare art objects.B. Radical changes in archiving practices.C. Recovery of various missing documents.D. Increases in the value of museum exhibits.。
