职称英语综合A补全短文历年真题 1
All children in the United States have to receive an education, but the law does not say they have to be educated at school. A number of parents prefer not to send their children to school.(46) There are about 300,000 home-schoolers in the United States today. Some parents prefer teaching their children at home because they do not believe that public schools teach the correct religious values; others believe they can provide a better educational experience for their children by teaching them at home. (47)
David Guterson and his wife teach their three children at home. Guterson says that his children learn very differently from children in school: (48) For example, when there is heavy snowfall on a winter day, it may start a discussion or reading about climate, snow removal (去除) equipment, Alaska, polar bears (北极熊), and winter tourism. A spring evening when the family is out watching the stars is a good time to ask questions about satellites and the space program. (49)
Home schooling is often more interesting than regular schools, but critics say that home-schoolers are outsiders who might be uncomfortable mixing with other people in adult life. (50) However, most parents dont have the time or the desire to teach their children at home, so schools will continue to be where most children get their formal education.
A Interestingly, results show that home-schooled children quite often do better than average on national tests in reading and math.
B Critics also say that most parents are not well qualified to teach their children.
C Learning starts with the childrens interests and questions.
D Children who are educated at home are known as "home-schoolers."
E In some countries, however, children are educated by their parents.
F If the Brazilian rain forests are on the TV news, it could be a perfect time to talk about how rain forests influence the climate, and how deserts are formed
答案：46. D47. A48. C49. F50. B
参考答案：C E B F D
答案解析：
1、正确答案为C。 文章第一段第一句的意思是，很多人认为鲨鱼是危险的，总是试图伤害甚至威胁人类的性命。选项C的意思是：实际上，世界上400多种(鲨鱼)中94%的鲨鱼对人类是无害的。此旬的意思和第一句联系起来语意通顺，合乎逻辑，故选C。
2、正确答案为E。 And to make this。point clear,the museum has set up a special touching pool for children：为了清楚地说明这一点，博物馆专门为孩子们搭建了一个可以进行触摸(鲨鱼)的水池。第二段主要讲鲨鱼并不经常攻击人类，为了证明这一点，博物馆……选项E放入空格处很连贯，与原文意思相符，故E为正确答案。
3、正确答案为B。 此段的第一句被删除了，要求考生补全。空格后面举例说明过去8 至15年内鲨鱼种群消亡了多少，选项B(A shocking 100million sharks are killed every year around the world by humans.) 显然是本段的主题句，概括本段的意思，故B为正 确答案。
4、正确答案为F。空格前面讲的是渔民们捕杀鲨鱼的事情，选项F具体谈到被捕杀的鲨鱼有多大，选项F与前面叙述的内容形成一种逻辑上的`连贯关系，故F为正确答案。
5、正确答案为D。文章最后一段谈到现在的一些捕鲨方式快把鲨鱼捕尽了，选项D的意 思是：这种情况令人担忧，有些地区已经采取措施来保护这些特殊的鲨鱼(It is a worrying situation and some areas have put measures in place t0 protect these special fish.)，可见D是正确的。

General Elections in Britain are usually held only once every five years. Governments can seem to be remote from the people they represent. The process of protesting about government actions is very slow, even though everyone is permitted direct contact to their member of Parliament. (46)
Pressure groups will seek to influence those who have political power, such as members of Parliament. (47) If members of a pressure group feel that there is public support from outside their group for their demands, they will tell members of Parliament about this.
Pressure groups will thus seek to get support from the public. A powerful way of doing this is by making use of the mass media. (48) Meanwhile, the group will have to be sure of its facts, and fact-finding is thus an important part of its work. Up-to-date information can be made known to members of Parliament and to the general public.
Pressure groups will not only seek to make their causes known to government, but also try to inform and influence the public. (49)
Pressure groups may support political parties, but will lay stress only on some of their policies. For instance, the Monday Club will support the more right-wing policies of the Conservative Party.(50)
A A good example of this sort of activity is provided by the educational work of "Shelter", which fights for better housing for poor people
B They will want to tell them what policy their interest demands
C For all these reasons there is something of a vacuum between government and the governed, which pressure groups help to f
D There can also be public meetings, demonstrations, etc
E Governments always stay close to the people.
F However, a pressure group is not a political party, because it does not seek complete or continuous political power.
答案:
46. C 47. B 48. D 49. A 50. F

Do you have difficulty reading in class? If so, a special reading program that helps match sounds with letters could speed up your brain.
At least one out of every five elementary school students in the US has trouble learning to read, even when the students are good at other subjects._________ (46)
Researchers from Yale University, US, studied a group of children from New York and Connecticut State. As part of the study, 37 struggling readers received special tutoring.
Every day, instructors worked with them on recognizing how written letters represent units of sound called phonemes (音素). _________(47)
By the end of the school year, these children could read faster than before. They also made fewer mistakes, and understood more of what they read than they could earlier in the year.
As part of their study, the researchers used a special machine to take action photos of the students brains. _________(48) This is the same part of the brain that becomes active when good readers read. This activated brain area appears to include a structure that helps people recognize familiar written words quickly. In lower level readers, this structure remains inactive.
A year later, the brain structure was still working hard in the students who had gone through the special tutoring, and they continued to do well in reading tests._________ (49) However, some researchers still doubt the study. _________ (50)
A. Many adults are interested in matching sounds with letters.
B. The students also practiced reading aloud and spelling.
C. The biggest challenge for many of these kids, scientists say, is matching sounds with letters.
D. Another group in the study who went through a more traditional reading program didnt show the same progress.
E. The pictures showed all increase in activity in the back of the brain on the left side.
F. They believe that reading without making any noise or linking words to sounds is more efficient.
试题答案及解析
46.C。文章的题目是：用较快的速度阅读。第二段的第一个句子说的是：在美国五个小学生中至少有一个在学习阅读方面有困难，虽然这些学生其他科目都不错。这是一个总的说明，接着的句子应该具体说明。C就是进一步的说明：科学家说，这些孩子中的许多人的最大困难是如何使得读音和字母对应起来。
47.B。第四段的第一句话说的是：每天老师帮助他们弄懂字母是如何表达被称做音素的语音单位的。但光弄懂是不够的，还需要实践。所以选B：学生还练习朗读和拼写。
48.E。第六段说的是：作为研究的一部分，研究人员用一个特殊的`机器拍摄学生大脑运动的照片。B说的是：照片显示左大脑后部的活动增加了。
49.D。倒数第二段的第一句讲的是试验组的情况。D讲的是用传统方法的情况，放在一起可以构成对比，很连贯。
50.F。最后一段的第一句说的是：然而，有些研究人员仍然不太相信这一研究。从提供的选项中的第一个词组可以看出，只有F是合适的，因为它的起始词是They，指some researchers。

A price represents the value of a goods or service for both the seller and the buyer. Price planning is systematic decision making by an organization regarding all aspects of pricing.
The value of a goods or service can involve both tangible and intangible marketing factors. An example of a tangible marketing factor is the cost savings__1__. An example of an intangible marketing factor is a consumer‘s pride in the ownership of a Lamborghini rather than another brand of automobile. For an example to take place，both the buyer and seller must feel that the price of a goods or service provides an equitable value. To the buyer，the payment of a price reduces purchasing power __2__. To the seller，receipt of a price is a source of revenue and an important determinant of sales and profit levels.
Many words are substitutes for the term price： admission fee，membership fee，rate，tuition，service charge，donation，rent，salary，interest，retainer，and assessment. No matter what it is called，__3__：monetary and non-monetary charges，discounts，handling and shipping fees，credit charges and other forms of interest，and late-payment penalties.
A non-price exchange would be selling a new iron for 10 books of trading stamps or an airline offering tickets as payment for advertising space and time. Monetary and non-monetary exchange may be combined. This is common with automobiles，__4__. This combination allows a reduction in the monetary price.
From a broader perspective，price is the mechanism for allocating goods and services among potential purchasers and for ensuring competition among sellers in an open market economy. If there is an excess of demand over supply，prices are usually bid up by consumers. If there is an excess of supply over demand，__5__.
Exercise：
A a price contains all the terms of purchase
B obtained by the purchase of a new bottling machine by a soda manufacturer
C where the consumer gives the seller money plus a trade-in
D available for other items
E prices are usually reduced by sellers
F price means what one pays for what he wants

What is a Profit
Gross profit is the difference between what a business firm sells its product for and what it costs to produce that product. The merchant buys $200，000 worth of merchandise during the year and sells it for $270，000. His gross profit is $70，000. The percentage difference between his cost and the selling price is 35 percent， and he calls this markup.
Entrepreneurship is directly responsible for production. The business person （entrepreneur） takes a cue from consumers in deciding what they want - or， in the case of a new product， __1__.
Profit means different things to different people. According to some public opinion polls， many people are not sure what it is， but they are sure __2__. Workers may look at profit as an unfairly large payment to the entrepreneur that deprives them of a higher wage. The business person thinks of profit __3__. During negotiations before the settlement of the second baseball strike in August， 1985， the Players‘ Association claimed the owners had made profits of $91 million， an accounting firm said owner profits were $43 million， and the owners insisted they had lost $9 million. The truth was that all three were correct. The disparity in the figures was due to the fact that each group was defining profit differently. Let us now see if we can develop a more exact definition of what profit is.
Net profit is __4__——rent，wages，and interest-and setting aside money to allow for the loss due to depreciation （wearing out） of capital. Our merchant has to subtract from his gross profit his payments for rent （$6，000）， wages （$20，000）， interest on money borrowed （$1，000）， repairs and upkeep （$1，000）， taxes （$1，000）， electricity and other expenses $1，000. Expenses for operating the business come to $30，000. Gross profit is $70，000， and net profit is $40，000.
Economists have a narrower definition of what constitutes profit. They are concerned with payment for all the resources that have gone into production， __5__， like those listed above， or from inside the business.
Exercise：
A what profit really means
B it is too large and represents too much of the consumer‘s dollar
C whether they come from outside the business
D as the difference between total revenue and total cost
E what the business person has left after paying expenses
F what they might want

The term supermarket usually refers to an institution in the grocery retailing field. most supermarkets emphasize price. some use price offensively by featuring low prices in order to attract customers. other supermarkets use price more defensively by relying on leader pricing to avoid a price disadvantage. since supermarkets typically have very thin gross margins, they need high levels of inventory turnover to achieve satisfactory returns on invested capital.

Why Would They Falsely Confess?
Why on earth would an innocent person falsely confess to committing a crime? To most
people, it just doesnt seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation (审讯) room. Under the right conditions, peoples minds are susceptible(易受影响的) to influence, and the pressure put on suspects during police grillings (盘问) is enormous. _________ (46) "The pressure is important to understand, because, otherwise, its impossible to understand why someone would say he did something he didnt do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess." Developmental psychologist Allison Redlich recently conducted a laboratory to determine how likely people are to confess to things they didnt do._________ (47) The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.
Redlichs findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed._________(48) Of the 15-to- 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds.
"Theres no question that young people are more at risk," says Saul Kassin, Professor at Williams College, who has done similar studies with similar results. _________(49) Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation--not hours of aggressive questioning--and still, most participants falsely confessed.
Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. _________ (50)
A. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems.
B. "In some ways," says Kassin, "false confession becomes a rational decision."
C. "Its a little like somebodys working on them with a dental (牙齿的) drill," says Franklin Zimring, a law professor at the University of California at Berkeley.
D. "But adults are highly vulnerable too."
E. How could an innocent person admit to doing something he didnt do?
F. Redlich also found that the younger the participant, the more likely a false confession.
试题答案解析
46.C。这一段谈的是pressure方面的`事。请注意在这个空格后面是一段引言，但没有原说话人的名字，这也给我们提示，在填入部分里应该有原说话人的名字，这样可以考虑的有B、C、F三个选项。从内容上进一步考虑，应选C。
47.A。这里填入的部分是对Redlich所做试验的描述，下文又讲到计算机，所以不难确定选A。
48.F。这一段讲的是Redlich试验的结果，一开始就讲了她的finding，填入的部分里有also这个词，正好接上。而后面的一句话则用更具体的数据来支持她的结论：越年轻，越可能做假供。
49.D。Saul Kassin同意Redlich的结果，她认为年轻人风险大(more at risk)，但同时她又认为成年人也十分脆弱(vulnerable)。
50.B。由于在审讯过程中受到压力，许多人认为做假供是一种摆脱厄境的方法，因而也是一种合理的决定

Mobile Phones
Mobile phones should carry a label if they proved1 to be a dangerous source of radiation, according to Robert Bell, a scientist. And no more mobile phone transmitter towers should be built until the long-term health effects of the electromagnetic radiation they emit are scientifically evaluated, he said. “Nobody’s going to drop dead overnight2 but we should be asking for more scientific information,” Robert Bell said at a conference on the health effects of low-level radiation. 1
A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill-effets on humans from electromagnetic radiation. According to Robert Bell, there are 3.3 million mobile phones in Australia alone and they are increasing by 2,000 a day3. 2
As well, there are 2,000 transmitter towers around Austrnlia, many in high density residential areas5. 3 The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby.
Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds, child care centres, hospitals, sports playing fields and residential areas with a high percentage of children. 4 He adds that there is also evidence that if cancer sufferers are subjected to electromagnetic waves the growth rate of the disease accelerates.
5 According to Robert Bell, it is reasonable for the major telephone companies to fund it. Besides, he also urges the Government to set up a wide-ranging inquiry into possible health effects.
词汇: mobile /5mEubail/ adj.移动的 circulate /5sE:kjuleit/ v.流传 electromagnetic /IlektrEJ5mA^nItIk/ adj.电磁的 density /5densiti/ n.密度 transmitter tower发射塔 disregard /7disri5^B:d/ v.不顾 shield /Fi:ld/ n.隔离屏 accelerate /Ak5selEreit/ v.加速，加快注释：
1. 动词 prove用的是过去式形式 proved，这是虚拟语气表示假设的用法。
2. Nobody’s going to drop dead overnight …“没有人会在一个晚上倒地死去……” overnight是副词，意为“一夜间;一下子;整夜”。如： This stadium was not built overnight.这个体育场不是一下子建起来的。 On his way to Europe, John stayed with his parents in Chicago overnight.在去欧洲的途中，约翰在芝加哥他父母那儿呆了一个晚上。
3.介词 by表示“以……(速的度增加)”。
4.介词 by表示“到……前”。如： By Thursday morning you should complete writing the experiment report. 到周四上午你应该写完实验报告。 5. many in high density residential areas 是独立主格结构。注意它省略了 being，即 many (being) in high density
residential areas。此外， many指的是 many transmitter towers。
6. at a rate more than three times that of adults可以理解为 at a rate (that is) more than three times that of adults.意为“以比成人多两倍的比率……”短语中的 that指代 rate。倍数的表达法是：“数字 +times+名词/that”。如： His salary is three times that of mine. 他的薪水比我多两倍。 The sales volume of refrigerators in 2000 was twice that in 1999. 2000年冰箱的销量比 1999年多一倍。练习：
A He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults6. B By the year 20004 it is estimated that Australia will have 8 million mobile phones: nearly one for every two people. C “If mobile phones are found to be dangerous, they should carry a warning label until proper shields can be devised,” he said. D Then who finances the research? E For example, Telstra, Optus and Vodaphone build their towers where it is geographically suitable to them and disregard the need of the community. F The conclusion is that mobile phones brings more harm than benefit.
答案与题解：
1. C “空 1”应该填入与 low-level radiation有关的内容，例如： low-level radiation究竟有害还是无害。所以， C是合适的选项。此外，直接引语也佐证了选择的合理性。
2. B“空 2”前面一句介绍了澳大利亚拥有手机的现状。选项 B的内容是对到 2000年之前手机发展前景的预测，内容连贯，是正确答案。
3. E 这一段的第一句说的`是，许多微波发射搭建在人口稠密的居民区。选项 E的内容涉及微波发射塔的地点选择只考虑到地理位置，而不顾及社区的安全。选项 E扩展了第一句表达的信息。此外选项 E 中出现 tower这个词，与第一句的 tower相呼应，也佐证了选择的合理性。
4. A “空 4”前面一句说的是 Robert Bell建议政府应该禁止在儿童比例高的地区(如学校操场、儿童医疗中心、居住小区等 )的 500米半径的范围内建造发射塔。选项 A说明为什么要这样做的原因，因而是答案。
5. D “空 5”后面一句说的是 major telephone companies出钱资助研究项目的问题，提示了 D是正确答案

Einstein Named "Person of the Century"
Albert Einstein, whose theories on space time and matter helped unravel (解决) the secrets of the atom and of the universe, was chosen as "Person of the Century" by Time magazine on Sunday.
A man whose very name is synonymous ( 同义的 ) with scientific genius, Einstein has come to represent more than any other person the flowering of 20th century scientific though that set the stage for the age of technology. "The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic, but technological—technologies that flowed directly from advances in basic science," wrote theoretical physicist Stephen Hawking in a Time essay explaining Einsteins significance. _________ (46)
Time chose as runner-up President Franklin Roosevelt to represent the triumph of freedom and democracy over fascism, and Mahatma Gandhi as an icon (象征) for a century when civil and human rights became crucial factors in global politics.
"What we saw was Franklin Roosevelt embodying the great theme of freedoms fight against totalitarianism, Gandhi personifying (象征，体现) the great theme of individuals struggling for their rights, and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances that helped expand the growth of freedom,"said Time Magazine Editor Walter Isaacson.
Einstein was born in Ulm, Germany in 1879_________ (47) He was slow to learn to speak and did not do well in elementary school He could not stomach organized learning and loathed taking exams , In 1905, however, he was to publish a theory which stands as one of the most intricate examples of human imagination in history. _________ (48) Everything else- mass,weight, space, even time itself--is a variable (变量). And he offered the world his now-famous equation (方程式): energy equals mass times the speed of light squared--E=mc2.
_________(49) "There was less faith in absolutes, not only of time and space but also of truth and morality " Einsteins famous equation was also the seed that led to the development of atomic energy and weapons. In 1939, six years after he fled European fascism and settled at Princeton University, Einstein, an avowed pacifist, signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did. _________(50) Einstein did not work on the project. Einstein died in Princeton, New Jersey in 1955.
A. "Indirectly, relativity paved the way for a new relativism in morality, art and politics,"Isaacson wrote in an essay explaining Times choices.
B. How he thought of the relativity theory influenced the general publics view about Albert Einstein
C. "Clearly, no scientist better represents those advances than Albert Elnstel .
D. Roosevelt heeded the advice and formed the "Manhattan Project" that secretly developed the first atomic weapon
E. In his early years, Einstein did not show the promise of what he was to become——
F. In his "Special Theory of Relativity," Einstein described how the only constant in the universe is the speed of light.
答案解析
46.C。本文主要讲爱因斯坦为20世纪人类科学做出的重大贡献。本段是理论物理学家史蒂芬霍金在《时代》杂志上发表的一篇评价爱因斯坦所做贡献的文章中的几句话。
他说世界在过去的'100年发生的变化比以往任何一个世纪都大得多，其原因不在于政治或经济，而在于技术——由于基础科学的进步而直接造就的新技术。两句话并未提及爱因斯坦，因此此处选C最合适：“显然，没有一位科学家能比爱因斯坦更好地代表这些科学进步。”those在此发挥了衔接作用。
47.E。本段简要介绍了爱因斯坦的早年生平。E说：“爱因斯坦在小时候并未显示日后会成为大科学家的任何天赋。”后一句话实际上是对E的详细解释。
48.F。本段主要介绍爱因斯坦提出的相对论。第一句话告诉我们l905年的时候爱因斯坦发表了人类历史上最具奇巧想象力的理论。第三、四句话是具体解释相对论，F说：“在‘特殊相对论’中，爱因斯坦描述了宇宙中为什么唯一恒定的是光速。”由此看来F放在此处最合适，其中constant和variable意思相反，构成词汇衔接。
49.A。本段是伊萨克森在《时代》杂志上的一篇文章中对相对论的深远意义所做的评述。他说：“相对论间接地为道德、艺术和政治领域中新相对主义的出现铺平了道路。”后一句是对此的进一步解释。
50.D。本段主要讲爱因斯坦与原子能和原子武器发展的关系。前一句告诉我们爱因斯坦于1939年在给罗斯福总统的一封信中敦促美国抢在纳粹德国之前研制原子弹，并签了名。D说：“罗斯福对这项建议十分关注，遂制定了秘密制造第一颗原子弹的‘曼哈顿计划’。”后一句说爱因斯坦未参与这项计划，其中the project指的就是the Manhattan Project。
