职称英语完型填空真题及答案(理工类A级)2012年职称英语完型填空真题及答案(理工类A级)Solar Power without Solar CellsA dramatic and surprising magnetic effect of light discovered by University of Michigan1 researchers could lead to solar power without traditional semiconductor-based solar cells.The researchers found a way to make an “optical 1 ,” said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics.Light has electric and magnetic components. Until now, scientists thought the 2 of the magnetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than 3 expected. 4 these circumstances, the magnetic effects develop strength equivalent to a strong electric effect.“This could lead to a new kind of solar cell without semicon ductors and without absorption to produce charge separation,” Rand said. “In solar cells, the 5 goes into amaterial, gets absorbed and creates heat. Here, we expect to have a very low heat load2. Instead of the light being absorbed, energy is stored in the magnetic moment3. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power 6.”What makes this possible is a previously undetected brand of “optical rectification4,” says William Fisher, a doc toral student5 in applied physics. In traditional optical rectification, light’s electric field causes a charge separation, or a pulling 7 of the positive and negative charges6 in a material. This sets up a voltage, similar to 8 in a battery.Rand and Fisher found that under the right circumstances and in right types of materials, the light’s magnetic field can also create optical rectification. The light must be shone through7 a 9 that does not 10 electricity, such as glass. And it must be focused to an intensity of 10 million watts per square centimeter8. Sunlight isn’t this intense on its own, but new materials are being sought that would work at lower intensities, Fisher said.“In our most recent paper, we show that incoherent light9 like sun light is theoretically almost as. 11 in producing charge separation as laser light is,” Fisher said.This new 12 could make solar power cheaper, the researchers say. They predict that with improved materials they could achieve 10 percent efficiency in 13 solar power to useable energy. That’s equivalent to today’s commercial-grade solar cells.“To manufacture 14 solar cells, you have to do extensive semiconductor processing,”Fisher said. “All we would need are lenses to focus the light and a fib er to guide it. Glass works for 15 . It’s already made in bulk10, and it doesn’t require as much processing. Transparent ceramics might be even better.”词汇:optical / ‘?ptik?l / adj.光学的incoherent /, ink?u’hi?r?nt/ adj.非相干的capacitive / k?’psitiv/ adj. 电容(量)的semiconductor /,semik?n’d?kt?/ n.半导体rectification /, rektifi’kei??n/ n.改正,修正ceramics / si’ rmiks/ n.陶瓷注释:1.University of Michigan:密歇根大学。

"FINAGLE" (欺骗) is not a word that most people associate with science. One reason is that the image of the scientist is of one who always (1) data in an impartial (不偏不倚) search for truth. In any debate - (2) intelligence, schooling, energy-the phrase "science says" usually disarms opposition.But scientists have long acknowledged the existence of a "finagle factor"-a tendency by many scientists to give a helpful change to the data to (3) desired results. The latest of the finagle factor in action es from Stephen Jay Gould, a Harvard biologist, who has (4) the important 19th century work of Dr. Samuel George Morton. Morton was famous in his time for analysing the brain (5) of the skulls as a measure of intelligence. He concluded that whites had the largest brains, that the brains of Indians and blacks were smaller,and (6), that whites constitute a superior race.Gould went back to Morton's original data and concluded that the (7) were an example of the finagle at work. He found that Morton's "discovery" was made by leaving out embarrassing data, (8) incorrect procedures, and changing his criteria - again, always in favour of his argument. Morton has been thoroughly discredited by now andscientists do not believe that brain size reflects (9).But Gould went on to say Morton's story is only an example of a mon problem in (10) work. Some of the leading figures in science are (11) to have used the finagle factor. Gould says that Isaac Newton fudged out (捏造) to supportat least three central statements that he could not prove. And so(12) Laudius Ptolemy, the Greek astronomer, whose master work, Almagest, summed up the case for a solarsystem that had the earth as its centre. Recent (13)indicate that Ptolemy either faked some key data orresorted heavily to the finagle factor.All this is important because the finagle factor isstill at work. For example, in the artificial sweetener controversy, for example, it is (14) that all the studies sponsored by the sugar industry find that the artificial sweetener is unsafe, (15) all the studies sponsored by the diet food industry find nothing wrong with it.1 A collects B invents C misuses D enables2 A of B over C in D with3 A convey B destroy C modify D acquire4 A created B written C examined D produced5 A size B shape C tissue D cell6 A however B then C though D therefore7 A results B experiments C ideas D suggestions8 A planning B making C using D searching9 A creativity B reliability C intelligence Doriginality10 A unusual B mental C scientific D manual11 A taught B believed C tried D allowed12 A was B had C could D did13 A studies B events C developments D decisions14 A feared B said C suggested D expected15 A if B while C because D although参考答案:1.

Direct observation of its center is impossible, so researchers must (1) to other evidence.In 1889, a German scientist detected a severe earthquake in Japan. Geophysicists concluded that shock waves (2) jolts (晃动) from one side of Earth through the center to the other side. Then in 1936, Danish geophysicist Inge Lehmann studied the waves' (3) to determine thatwithin Earth's core of molten (熔化了的) iron lies a solid inner core - but (4) that core was made of eluded (难倒) her. Other geophysicists quickly determined that Lehmann's inner core was posed mostly (5) iron. Since then, Lehmann's discovery has (6) conventional Earth science.But now scientists are challenging traditional theory with new and radical (7). For example, Earth's center could actually contain an "inner core within the inner core," claim Ishii and colleague Adam Dziewonski.Analyzing hundreds of thousands of earthquake wave (8), they maintain that the inner core has at its heart a tiny, even more solid sphere (球体). This sphere "may be the oldest fossil (9) from the formation of Earth," says Dziewonski.Dziewonski and Ishii speculate that shortly (10) Earth formed around 4.8 billion years ago, a giant asteroid (小行星) smashed into the young pla and nearly melted it. But Earth's center didn't quite melt; it (11) mass as the pla cooled. The core within a core may be the kernel (核心)that endured. "Its presence could change our basic ideas about the (12) of the pla," Dziewonski says.Dziewonski's idea is tame (温和的) pared to the (13) theories of independent geophysicist J. Marvin Herndon. Earth's inner core is made not of iron, he claims, but a (14) of nickel and silicon. Herndon has a truly revolutionary notion: Within the nickel silicide (硅化物) inner core is also an "inner" inner core - an 8 km-wideball of the element uranium. Uranium is radioactive. Herndon thinks the uranium releases heat energy as its atoms (15) fission-split and crash into one another in achain reaction. In other words, we may live on top of a gigantic, "natural" nuclear power plant.1 A try B leave C turn D point2 A create B receive C feel D overe3 A work B solution C job D patterns4 A whether B what C why D how5 A from B within C of D to6 A followed B dominated C restored D opposed7 A ideas B demands C phenomena D movements8 A things B acts C methods D records9 A taken B benefited C left D kept10 A after B before C since D when11 A expanded B modified C gained D melted12 A size B origin C structure D shape13 A radical B traditional C classical D conventional14 A system B copy C model D pound15 A charge B last C experience D show参考答案:1.

There are many (1) of this.Its front flippers (鳍状肢), used for steering andstability, are traces of feet.Immense strength is (2) into the great body of the big whales, and in fact most of a whale's body is one gigantic muscle. The blue whale's pulling strength has beenestimated (3) 400 horsepower. One specimen was reported to have towed (拖) a whaling vessel for seven hours at the (4) of eight knots (节).An angry whale will (5) a ship. A famous example ofthis was the fate of whaler Essex, (6) was sunk off the coast of South America early in the last century. More recently, steel ships have (7) their plates buckled (使弯曲) in the same way. Sperm whales (抹香鲸) were known to seize the old-time whaleboats in their jaws and crush them.The greatest (8) of whales is their diving ability. The sperm whale dives to the bottom for his (9) food, the octopus (章鱼). In that search he is known to go as far down as 3,200 feet, where the (10) is 1,400 pounds, to a square inch. Doing so he will (11) underwater long as one hour. Two special skills are involved in this: storing up enough (12) (all whales are air-breathed) and toleratingthe great change in pressure. Just how he does itscientists have not (13). It is believed that some of the oxygen is stored in a special (14) of blood vessels, rather than just held in the lungs. And it is believed that aspecial kind of oil in his head is some sort of pensating mechanism that (15) adjusts the internal pressure of his body. But since you can't bring a live whale into the laboratory for study, no one knows just how these things work.1 A aspects B signs C ways D reasons2 A worked B divided C built D moved3 A at B in C of D with4 A number B degree C distance D rate5 A abandon B attack C leave D board6 A as B who C which D that7 A had B operated C seen D caught8 A interest B job C danger D mystery9 A favorite B fast C new D sufficient10 A depth B pressure C level D size11 A set B bee C remain D rest12 A heat B energy C food D oxygen13 A witnessed B determined C applied D calculated14 A system B place C arrangement D equipment15 A mentally B artificially C manually D automatically参考答案:1.

It is (10) that by 1996, 61 percent of American managers will be using some sort of electronic work station. In order for managers to be sure that the puter-based information they are receiving is (11), they need to understand how puters work.

职称英语理工类A级完形填空超级预测题(附答案)Better Solar Energy Systems: More Heat, More LightSolar photovoltaic thermal until now they haven’t been very good at the heatsolar thermal collector. That’s because they operate at low temperatures to cool crystalline silicon solar cells, which lets the silicon generate more electricity but isn’t a v ery efficient way to gather heat.That’s a problem of economics. Good solar hot-water systems can much more energy than a solar-electric system at a substantially lower cost. And it’s also a problem:the space on the roof, leaving little room for thermal applications.In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen’s University, Canada.“ Most solar panels are made with crystalline silicon,but you can also make solar cells out ofamorphous silicon, commonly known as thin-film silicon. They don’t create as much silicon, they have a greener footprint. Unfortunately,thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.“That means that their drops when you expose them to light ―the worst possible effect for a solar cell,” Pearce explains,which is one of the reasons thin- film by incorporating thin-film silicon in a new type of PVT. You don’t have to cool down thin-film silicon to make it work. In fact,Pearce’s group that by heating it to solar-thermal operating temperatures,near the boiling point of water, they could make thicker cells that overcame the Staebler-Wronski effect. When they the thin-film silicon directly to a solar thermal energy collector , they also found that by ,th ey boosted the solar cell’s electrical efficiency by over 10 percent.1.

Where Have All Our Visitors Gone? Sixty years ago, a man named Kenneth Arnold saw something that people are still【C1】______today—something that changed popular culture forever. Flying his plane over mountains in the US state of Washington, he saw a line of strange objects, either crescent-shaped or disc-like, flying【C2】______the motion of a saucer skimming on water. The media soon picked up on the story—the Flying Saucers were here! Was the earth being【C3】______by creatures from another planet? Soon, so many sightings were made that the US military began to【C4】______. It called these strange objects UFOs —Unidentified Flying Objects, and that is how they are【C5】______today. Military investigations found no evidence of visitors from outer space. But that did not stop the true【C6】______. The military were【C7】______up, they said. Or【C8】______it was because the travelers from space were of such superior intelligence that they could hide from the most sophisticated military analysts. People have always seen strange lights in the sky. In the past these were explained in【C9】______ways. In a world where religion was less influential and science fiction was popular, signs from god were replaced by visitors from other【C10】______. The date of the first UFO signings was also significant. In 1947, World War II had just ended and the【C11】______war was just beginning. Humanity seemed locked in endless conflicts. Like generations before them, people looked【C12】______the skies for help. But instead of seeking God, they looked for help from super-intelligent aliens with【C13】______technology. Belief in UFOs became the first religion of science. However, even people who believe in UFOs are not quite sure why they visit the earth. The universe is a big place and it is【C14】______to assume that there is life somewhere out there. It is possible that aliens have worked out how to travel through space. Yet some people report that they have been taken by aliens and have had experiments 【C15】______on them. Why would anyone travel across half the universe to conduct medical experiments on people living in small towns in the United States?1.【C1】A.lookingB.seeingC.seekingD.feeling正确答案:B解析:see和look,seek这三个词的根本区别在于see有一个终点(endpoint),而look和seek是没有终点的。

The Great Newspaper War Up until about 100 years ago, newspapers in the United States appealed only to the most serious readers. They used 【C1】______illustrations and the articles were about politics or business. Two men changed that—Joseph Pulitzer【C2】______the New York World and William Randolph Hearst of the New York Journal. Pulitzer bought the New York World【C3】______1883. He changed it from a traditional newspaper into a very【C4】______one overnight. He added【C5】______illustrations and cartoons. And he told his reporters to write articles on【C6】______crime or scandal they could find. And they did. One of them even pretended she was crazy and then she【C7】______to a mental hospital. She then wrote a series of articles about the poor treatment of【C8】______in those hospitals. In 1895, Hearst came to New York from【C9】______California. He wanted the Journal to be more sensational and more exciting【C10】______the World. He also wanted it to be【C11】______, so he reduced the price by a penny. Hearst attracted attention because his headlines were bigger than【C12】______. He often said, “Big print makes big news. “Pulitzer and Hearst did anything they【C13】______to sell newspapers. For example, Hearst sent Frederic Remington, the famous illustrator,【C14】______pictures of the Spanish-American War. When he got there, he told Hearst that no fighting was【C15】______. Hearst answered, “You furnish the pictures. I’ll furnish the war. “1.【C1】A.noB.manyC.a lotD.little正确答案:A解析:此题考查上下文理解,下文提到change,则之前无图解,故选no。

Until now, scientists thought the 2 of the magnetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than 3 expected. 4 these circumstances, the magnetic effects develop strength equivalent to a strong electric effect.“This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation,” Rand said. “In solar cells, the 5 goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load2. Instead of the light being absorbed, energy is stored in the magnetic moment3. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power 6.”What makes this possible is a previously undetectedbrand of “optical rectification4,” says William Fisher, a doctoral st udent5 in applied physics. In traditional optical rectification, light’s electric field causes a charge separation, or a pulling 7 of the positive and negative charges6 in a material. This sets up a voltage, similar to 8 in a battery.Rand and Fisher found that under the right circumstances and in right types of materials, the light’s magnetic field can also create optical rectification. The light must be shone through7 a 9 that does not 10 electricity, such as glass. And it must be focused to an intens ity of 10 million watts per square centimeter8. Sunlight isn’t this intense on its own, but new materials are being sought that would work at lower intensities, Fisher said.“In our most recent paper, we show that incoherent light9 like sunlight is the oretically almost as. 11 in producing charge separation as laser light is,” Fisher said.This new 12 could make solar power cheaper, the researchers say. They predict that with improved materials they could achieve 10 percent efficiency in 13 solar pow er to useable energy. That’s equivalent to today’s commercial-grade solar cells.“To manufacture 14 solar cells, you have to do extensive semiconductor processing,” Fisher said. “All we would need are lenses to focus the light and a fiber to guide it. Glass works for 15 . It’s already made in bulk10, and it doesn’t require as much processing. Transparent ceramics might be even better.”词汇:optical / ‘ptikl / adj.光学的incoherent /, inku’hirnt/ adj.非相干的capacitive / k’paelig;sitiv/ adj. 电容(量)的semiconductor /,semikn’dkt/n.半导体rectification /, rektifi’kein/ n.改正,修正ceramics / si’ raelig;miks/n.陶瓷注释:1.University of Michigan:密歇根大学。

Obtaining Drinking Water from Air Humidity
Not a plant to be seen,the desert ground is too dry.But the air contains water,and research scientists have found a_________(51)of obtaining drinking water from air humidity.The system isbased pletely on renewable energy and is therefore autonomous.
Cracks permeate the dried-out desert ground and the landscape bears testimony to the lack of water.But even here,where there are no lakes,rivers or groundwater,considerable quantities of water are stored in the air.In the Negev desert in Israel,for example,annual average relative air hu-midity is 64 percent-in every cubic meter of air there aye 11.5 milliliters of water.
German research scientists have found a way of converting this air humidity autonomously intodrinkable water."The
process we have developed is based exclusively on renewable energy sources_______(52)thermal solar collectors and photovoltaic ceils,_________(53)makes this methodpletely energy-autonomous.It will_______(54)function in regions where there is no electricalinfrastructure."says Siegfried Egner,head of the research team.The principle of
the_______ (55)is as follows:hygroscopic brine-saline solution which absorbs moistureruns down a tower-shapedunit and absorbs water from the air.It is then
sucked_________(56)a tank a few meters off the ground in which a vacuum prevails.Energy from solar
collectors_________(57)up the brine,whichis diluted by the water it has________(58).
Because of the vacuum,the boiling point of the liquid is lower thaa it would be under_____ (59)atmospheric pressure.This effect is known from the mountains:as the atmospheric pressure there is lower than in the valley,water boils at temperatures distinctly below 100~C.The evaporated, non-saline water is condensed and runs down through a pletely filled tube in a controlled manner.The gravity of this water column_________(60)produces the
vacuum and so a vacuum pump is not needed.The reconcentrated brine________(61)down the tower surface again to absorb moisture from the air.
"The concept is suitable for various
water_________(62).Single-person units and plants supplying water to entire hotels are conceivable,"says Egner.Prototypes have been built for______
(63)system ponents-air moisture absorption and vacuum evaporation-and the research scientistshave
Mready________(64)their interplay on a laboratory scale.In a further________(65)the researchers intend to develop a demonstration facility.
