职称英语理工类C级补全短文练习及答案2017年职称英语理工类C级补全短文练习及答案The Bilingual BrainWhen Karl Kim immigrated to the United States from Korea s a teenager, he had a hard time learning English. Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language. As a graduate student, Kim worked in the lab of Joy Hirsch, a neuroscientist in New York. 1 They found evidence that children and adults don't use the same parts of the brain when they learn a second language.The researchers used an instrument called an MRI( magnetic resonance imaging) scanner to study the brains of two groups ofbilingual people. 2 . The other consisted of people who, like Kim, learned their second language later in life. People from both groups were placed inside the MRI scanner. This allowed Kim and Hirsch to see which parts of the brain were getting more blood and were more active. They asked people from both groups to think about what they had done the day before, first in one language and then the other. They couldn't speak out loud because any movement would disrupt the scanning.Kim and Hirsch looked specifically at two language centers inthe brain - Broca's area~ , which is believed to control speech production, and Wernicke's area, which is thought to process meaning. Kim and Hirsch found that both groups of people used the same part of Wernicke's area no matter what language they were speaking. 3People who learned a second language as children used the same region in Broca's area for both their first and second languages. People who learned a second language later in life used a different part of Broca's area for their second language. 4 Hirsch believes that when language is first being programmed in young children, their brains may mix the sounds and structures of all languages in the same area. Oncethat programming is complete, the processing of a new language must be taken over by a different part of the brain.A second possibility is simply that we may acquire languages differently as children than we do as adults. Hirsch thinks that mothers teach a baby to speak by using different methods involving touch, sound, and sight. 5 A But their use of Broca's area was different.B One group consisted of those who had learned a second language as children.C How does Hirsch explain this difference?D We use special parts of the brain for language learning.E And that is very different from learning a language in a high school or college class.F Their work led to an importantdiscovery.FBACE练习：A But their use of Broca's area was different.B One group consisted of those who had learned a second language as children.C How does Hirsch explain this difference?D We use special parts of the brain for language learning.E And that is very different from learning a language in a high school or college class.F Their work led to an important discovery.答案与题解：1.F根据本空的后一句：They found evidence that children and adults don’t use the same parts of the brain when they learn a second language.其中they found evidence与discovery相互应。

2017年职称英语理工类补全短文常考题(11)More and more Americans are living atone. Some live atone becauseof 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 madeup 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 nowsocially acceptable, even fashionable, to live alone. As people get better jobs and become financially independent, it becomes possiblefor them to maintain a one-person household. (3) However, people whodo 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 ableto 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. DIt 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." 答案1.C 2.E 3.B4.F 5.D 1.8 2.C 3.A 4.C 5.B。

2017年职称英语理工类补全短文模拟习题及答案（6）Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant “superbugs”.2The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry. ____1____Some 20,000 tons of antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth. ____2____Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat3. But far more of the drugs end up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology m Dubendorf. ____3____With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route for spreading resistance,4 he said. The drugs contaminate the crops, which are then eaten. ____4____Mueller is particularly concerned about a group of antibiotics called sulphonamides. ____5____ His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria.5 But vets are not treating the issue seriously.There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and are not broken down by conventional sewage treatment.练习：A They do not easily degrade or dissolve in water.B And manure contains especially high levels of bugs that are resistar.t to antibiotics, he says.C Animal antibiotics is still an area to which insufficient attention has been paid.D But recent research has found a direct link between the increased use of these farmyard drugs and the appearance ofantibiotic-resistant bugs that infect people.E His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal feed.F They could also be leaching into tap water pumped from rocks beneath fertilized fields.答案与题解：1.E 本句中包含he这个代词，故上文中必定有它的先行词，his findings又表明此人应该是从事科研工作的，句中又提到Switzerland，考虑这种种因素，填入E是正确的。

My father had his first three heart attacks when he was only thirty-one. _____________(46) I grew up with heart disease. It was there, but I didn’t take it seriouly.When I was thirty-one, my blood cholesterol（胆固醇）level was measured for the first time.It was 311 mg/dl, the doctor told me- an extremely high level that put me at a very high high risk of heart disease, especially with my family history. He sent me to the National Institutes of Health（NIH）to be screened for participation in a clinical trial._____________(47)At NIH, physicians explained the degree of risk associated with my blood cholesterol level and the nature of the experiment. Thistest involves putting a tube through a leg artery（动脉） up to the heart._____________（48）Learning about the risks of the experiment as well sa the risk associated with my raised blood cholesterol level scared the life out of me. Although I was excluded from participating in the study, the experience may well have saved my life.For the first time, I began to realize the seriousness of high blood cholesterol.___________(49) But equally important, I got a taste of what it is like to be a patient, to have tests done on me and to think of myself as sick.This was hard to take.This experience taught me two lifesaving lessons. First, although I felt fit and strong, I was actually at high risk for heart disease because of my high blood cholesterol level. And with my family histaory, it could not be ignored.________________(50)A Second, I could lower my blood cholesterol level simply by changing what I ate.B I was three years old at that time.C There is not enough oxygen in the blood.D It was a heart attack just waiting to happenE The trial was designed to test the effect of lowering blood cholesterol on the risk of heart disease.F The death rate for the test was only 1 in 100, I was assured.。

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 floweddirectly from advances in basic science," wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein's 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 freedom's 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 leam 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) . Andhe offered the world his now-famous equation (等量) ：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." Einstein's 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 Time's choices.B. How he thought of the relativity theory influenced the general public's view about Albert Einstein.C. "Clearly, no scientist better represents those advances than Albert Einstein."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.。

2017年职称英语理工类补全短文模拟习题及答案（15）A Memory Drug?IT’S DIFFICULT 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 research that 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 activity in their NMDA receptors，more LTP，and improved performance on 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 the synaptic basis of memory can be translated to people — and that 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 be able 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 movieEternal 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 memory by helping to initiate LTP.答案与题解：1.B 依据上一句的“很难想象一种提高人们记忆力的药会受到人们吹捧”;下面应该对这一现象做出解释，即这种药物有什么疗效;而后一句的Furthermore这一指示词起到了递进的作用，进一步说明这种药物的益处。
