2020年职称英语理工类C级补全短文练习题(4)A Memory Drug?It'sdifficult to imagine many things that people would welcome more than a memory-enhancing drug.____1____ Furthermore,such a drug could help people remember past experiences more clearly and help us acquire new information more easily for school and at work.As scientists learn more about memory,we are closing in on this tantalizing goal.1Some of the most exciting evidence comes from researchthat has built on earlier findings linking LTP2 and memory to identify a gene that improves memory in mice.____2____ Mice bred to have extra copies of this gene showed more activityin their NMDA receptors,more LTP,and improved performanceon several different memory tasks—learning a spatial layout3,recognizing familiar objects,and recalling a fear-inducing shock.If these basic insights about genes,LTP,and thesynaptic basis of memory can be translated to people—andthat remains to be seen—they could pave the way for memory-enhancing treatments.____3____ As exciting as this may sound,it also raises troubling issues.Consider the potential educational implications of memory-enhancing drugs.If memory enhancers were available,children who used them might beable to acquire and retain extraordinary amounts of information,allowing them to progress far more rapidly in school than they could otherwise.How well could the brain handle such an onslaught of information? What happens to children who don't have access to the latest memory enhancers?Are they left behind in school—and as a result handicapped later in life?____4____ Imagine that you are applying for a job that requires a good memory,such as a manager at a technology company or a sales position that requires remembering customers' names as well as the attributes of different products and services.Would you take a memory-enhancing drug to increase your chances of landing the position? Would people who felt uncomfortable taking such a drug find themselves cut out of lucrative career opportunities?Memory drugs might also help take the sting out of disturbing memories that we wish we could forget but can't.4 The 2004 hit movie Eternal Sunshine of the Spotless Mind told the story of a young man seeking just such freedom from the painful memories of a romantic breakup.As you will see in the section on persistence later in the chapter,emotionally arousing events often create intrusive memories,and researchers have already muted emotional memories with drugs that block the action of key hormones.Should emergency workers who must confront horrifying accident scenes that can burden them with persisting memories be provided with such drugs? Should such drugs be given to rape victims who can't forget the trauma? Memory drugs might provide some relief to such individuals.But could they also interfere with an individual's ability to assimilate and come to terms with a difficult experience?5 ____5____练习:A.Like steroids for bulking up the muscles,these drugs would bulk up memory.B.A memory enhancer could help eliminate forgetting associated with aging and disease.C.What are the potential implications of memory-enhancing drugs for the workplace?D.We may find ourselves struggling with these kinds of questions in the not-too-distant future.E.There is a pill that you could take every day to allow you to remember everything.F.The gene makes a protein that assists the NMDA2 receptor,which plays an important role in long-term memoryby helping to initiate LTP.答案与题解:1.B依据上一句的“很难想象一种提升人们记忆力的药会受到人们吹捧”;下面应该对这个现象做出解释,即这种药物有什么疗效;而后一句的Furthermore这个指示词起到了递进的作用,进一步说明这种药物的益处。

2020年职称英语考试真题及答案:理工A补全短文第四部分补全短文Researchers Discover Why Humans Began Walking UprightMost of us walk and carry items in our hands every day. These are seemingly simple activities that the majority of us don’t question. But an international team of researchers, including Dr. Richmond from GW's Columbian College of Arts and Sciences,have discovered that human walking upright, may have originated millions of years ago as an adaptation to carrying scarce, high- quality resources. The team of researchers from the U. S., England, Japan and Portugal investigated the behavior of modern-day chimpanzees as they competed for food resources,in an effort to understand what ecological settings would lead a large ape — one that resembles the 6 million-year old ancestor we shared in common with living chimpanzees — to walk on two legs.“These chimpanzee s provide a model of the ecological conditions under which our earliest ancestors might have begun walking on two legs, ",said Dr. Richmond.The research findings suggest that chimpanzees switch to moving on two limbs instead of four in situations where they need to monopolize a resource. Standing on two legs allows them to carry much more at one time because it frees up their hands. Over time,intense bursts of bipedal activity may have led to anatomical changes that in turn became the subject of natural selection where competition for food or other resources was strong.Two studies were conducted by the team in Guinea. Thefirst study was conducted by the team in Kyoto University’s “ outdoor laboratory ” in a natural clearing in Bossou Forest. Researchers allowed the wild chimpanzees access to different combinations of two different types of nut — theoil palm nut,which is naturally widely available, and the coula nut, which is not. The chimpanzees’ behavior was monitored in three situations:(a) when only oil palm nuts were available,(b)when a small number of coula nuts were available,and(c) when coula nuts were the majority available resource.When the rare coula nuts were available only in small numbers, the chimpanzees transported more at one time. Similarly, when coula nuts were the majority resource, the chimpanzees ignored the oil palm nuts altogether. The chimpanzees regarded the coula nuts as a more highly-prized resource and competed for them more intensely.In such high-competition settings,the frequency of cases in which the chimpanzees started moving on two legs increased by a factor of four. Not only was it obvious that bipedal movement allowed them to carry more of this precious resource, but also that they were actively trying to move as much asthey could in one go by using everything available 一 eventheir mouths.The second study, by Kimberley Hockings of Oxford Brookes University, was a 14-month study of Bossou chimpanzees crop-raiding, a situation in which they have to compete for rare and unpredictable Resources. Here, 35 percent of the chimpanzees activity involved some sort of bipedal movement,and once again, this behavior appeared to be linked to a clear attempt to carry as much as possible at one time.参考答案: BAEFC。

The Magic of SoundMusic is one of the most beautiful forms of artistic expressions ever invented. In movies and plays, music has an added function :it not only moves people but also can shock people. Is it true that an ordinary musical instrument can be so powerful?Our eardrums can withstand sound within 20 to 80 decibels. Once sound exceeds this limit, even beautiful music will become car-splitting noise and harm health. A strong blast of high sound can twist and break a solid iron sheet. 46The noise from a plane 's engine is over 140 decibels. However, the sound of a flute is at most a few decibels. 47 It has been proven that people who have worked in an environment with a high sound intensity for a long time suffer varying degrees of heart disease or altered brain waves.In movies, sometimes the hero can produce a sound that ordinary people can 't hear and only those who have the same ability can feel. In nature, there is actually sound that is beyond our hearing. In physics, the sound that exceeds 20,000 Hz is called ultrasonic. 48 It does no harm to health.Sound less than 20 Hz is called infrasonic waves. When we move, the air will vibrate. 49 As the frequency of infrasonic waves is close to that of people 's internal organs,infrasonic wave may cause resonance in human bodies. As a result, people 's vision may weaken and internal organs may rupture. However, whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low, it won 't damage internal organs or a person 's healt h. 50When wind blows at a force of 3 or 4 over the sea, it will produce infrasonic waves of several decibels. Only typhoons can produce infrasonic waves of over 100 decibels. At present, scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.A. High sound of 150 decibels can kill a healthy rat.B. The vibration of air can produce infrasonic waves.C. We cannot play high-pitched music with ordinary musical instruments.D. If the intensity of infrasonic wave exceeds 160 decibels, it is extremely harmful.E. Dolphins, whales and bats can make such high-frequency sound.F. Therefore, the sound of ordinary musical instruments cannot harm your health.参考答案:46-50 AFEBD。

第一篇Powering a City? It’s a Breeze.The graceful wooden windmills that have broken up theflat Dutch landscape for centuries — a national symbol like wooden shoes and tulips — yielded long ago to ungainlymetal-pole turbines.Now, windmills are breaking into a new frontier. Though still in its teething stages, the “urban turbine” is ahigh-tech windmill designed to generate energy from the rooftops of busy cities. Lighter, quieter, and often more efficient than rural counterparts, they take advantage of the extreme turbulence and rapid shifts in direction that characterize urban wind patterns.Prototypes have been successfully tested in several Dutch cities, and the city government in the Hague has recently agreed to begin a large-scale deployment in 2003. Current models cost US $8, 000 to US $12, 000 and can generate between 3, 000 and 7, 000 kilowatt hours of electricity per year. A typical Dutch household uses 3,500 kilowatt hours per year, while in the United States, this figure jumps to around 10, 000 kilowatt hours.But so far, they are being designed more for public or commercial buildings than for private homes. The smallest of the current models weigh roughly 200 kilograms and can be installed on a roof in a few hours without using a crane.Germany, Finland and Denmark have also been experimenting with the technology, but the ever-practical Dutch are natural pioneers in urban wind power mainly because of the lack of space. The Netherlands, with 16 million people crowded into a country twice the size of Slovenia, is the most densely populated in Europe.Problems remain, however, for example, public safety concerns, and so strict standards should be applied to any potential manufacturer. Vibrations are the main problem in skyscraper-high turbine. People don’t know what it would be like to work there, in an office next to one of the big turbines. It might be too hectic.Meanwhile, projects are under way to use minimills to generate power for lifeboats, streetlights, and portable generators. “I think the thing about wind power is that you can use it in a whole range of situations,” said Corin Millais, of the European Wind Energy Association. “It’s a very local technology, and you can use it right in your backyard, I don’t think anybody wants a nuclear power plant in their backyard.”31. What are the symbols of the Netherlands according to the first paragraph?A. The flat landscape.B. Wooden shoes and wooden windmills.C. Metal-pole turbines.D. Both A and B.32. Which statement best describes the urban turbine mentioned in the second paragraph?A. It is a windmill put on rooftops of buildings for energy generation.B. It is a high-tech machine designed to generate energy for urban people.C. It is light and quiet and therefore more efficient.D. It is driven by urban wind.33. The smallest models of an urban turbineA. is designed for private homes.B. weighs 2,000 kilograms.C. can be carried up to the rooftop without a crane.D. can he installed with a crane.34. Netherlands leads in the urban turbine technology becauseA. the Dutch are natural pioneers.B. the Dutch have a tradition with windmills.C. the Netherlands is windier than Germany, Finland and Slovenia.D. the Netherlands is a small country with a large population.35. According to the last paragraph, what are the advantages of wind power technology?A. It can be used for different purposes.B. It can replace nuclear power plant.C. It can be installed in one’s backyard.D. Both A and C.。

More and more Americans are living atone. Some live atone because of divorce or the death of a partner. (1) According
to a recent U.S. census (人口普查), 25 percent of all households in the U.S. are made up of just one person. This
is a dramatic change from the extended families of just a couple of generations ago.
The typical person living alone is neither old nor lonely.
(2) The majority of these people have chosen to live alone. They are responding to decreasing social pressure to get married and have a family.
It's now socially acceptable, even fashionable, to live alone. As people get better jobs and become financially independent, it becomes possible for them to maintain a one-person household. (3) However, people who do get married are marrying at a later age and divorcing more often.
The number one reason given by most people for living
alone is that they simply enjoy doing what they want when
they want to do it. "Living alone is a luxury," says Nina Hagiwara, 38. "Once you do it, you can't ever go back to
living with others." David C'Debaca, 46, agrees. (4)
Children think that being grown up means being able to do exactly as they please.
(5) The chance to discover whether that freedom is as wonderful as it sounds is a chance more and more Americans are taking.
A There's more pressure to get married nowadays.
B The growing number of women with good jobs has done much to increase the number of people living alone.
C However, even more people are living alone because they have chosen to.
D It seems that many grown-ups today are realizing that childhood dream.
E In fact, a quarter of the 23 million single people in the U.S. are under the age of35.
F He says, "1 like being by myself."

Little Lady Starts Big War
Harriet Beecher Stowe had poured her heart into her anti-slavery book "Uncle Tom's Cabin." (46) The publisher was so doubtful that he wanted her to split the publishing costs with him, and all she hoped was that it would make enough money for her to buy a new silk dress.
But when the first 5,000 copies were printed in 1852. They sold out in two days. In a year the book had sold
300,000 copies in the United States and150,000 in England. (47) Within six months of its release, a play was made from
the book which ran 350 performances in New York and remained America's most popular play for 80 years. It might appear
that "Uncle Tom's Cabins was universally popular, but this
was certainly not true. Many people during those pre-Civil
War days--particularly defenders of the slavery system--condemned it as false propaganda and poorly written melodrama (传奇剧作品).
Harriet did have strong religious views against slavery (When asked how she came to write the book, she replied:
"God wrote it."), and she tried to convince people slavery
was wrong, so perhaps the book could be considered propaganda.
(48)
Though she was born in Connecticut in 1832, as a young woman she moved to Cincinnati, Ohio, when her father accepted the presidency of newly founded Lane Theological Seminary (神
学院). Ohio was a free state, but just across the Ohio River
in Kentucky, Harriet saw slavery in action. (49) In 1851, Harriet Beecher Stowe began her book.
Its vast influence strengthened the anti-slavery movement and angered defenders of the slave system. (50)
In fact, when Abraham Lincoln met Harriet at the White House during the Civil War, he said, "So, this is the little lady who started this big war."
A She had read a lot about the slavery system.
B Today some historians think that it helped bring on the American Civil War.。
