托福模拟考试及答案解析(11)

托福模拟考试及答案解析（11）(1~12/共51题)阅读理解THE TRICKSTER FIGURE IN MYTHOLOGY 1 In the study of mythology, the character known as the trickster is a god, spirit, human, or animal who breaks the rules of the gods or nature, sometimes maliciously but usually with results that are positive. The rule breaking often takes the form of mischief or thievery. The trickster is usually male but occasionally disguises himself in female form. He can be cunning or foolish, or both, and often very humorous. His curiosity leads him into trouble, but he rescues himself with his sly wit. When he plays tricks, he performs important cultural tasks that benefit humans, and for this reason the trickster is a significant figure in world mythology.2 In different cultures, the trickster and the hero are combined in various ways. In Greek mythology, Prometheus steals fire from the gods and gives it to humans, a feat making him more of a hero than a trickster, and he is usually portrayed as an intellectual. In many Native American stories, Coyote also steals fire from the gods, but Coyote is usually more of a jokester or a prankster than an intellectual.3 The trickster is both creator and destroyer, giver and taker, one who tricks others and is tricked in return. The pranks of the trickster are compulsive and uncontrollable. He does not act consciously; he acts out of passion and impulse. He knows neither good nor evil, yet he is responsible for both. He possesses no morals, yet through his behavior morality comes into being. According to psychologist Carl Jung, the trickster is "a primitive cosmic being of divine-animal nature, on the one hand superior to man because of his superhuman qualities, and on the other hand inferior to him because of his unreason and unconsciousness."4 In Native American mythology, the majority of trickster myths concern the creation or transformation of the earth. Such stories have a trickster who is always wandering, who is always hungry, who is not guided by normal ideas of good and evil, and who possesses some magical powers. In some stories he is a deity, and in others he is an animal or human that is subject to death. Several of these myths feature Raven or Coyote as the trickster-hero.5 In many creation myths of the Pacific Northwest, Raven illustrates the transformational nature of tricksters. Raven is the greatest shapeshifter of all and can change into anything to get what he wants. In one story, there is darkness at the beginning of the world, so Raven decides he will find light. He flies far from the earth, searching in the darkness, until he spots a glimmer of light coming from a window in the house of the gods. Raven knows the gods are protective of their possessions, so he devises a trick. He perches on a pine branch next to the house and watches each day as the chief god's daughter draws water from a nearby lake. He magically transforms himself into a pinyon seed and falls into the girl's drinking cup. The girl swallows the seed, which grows within her body, and she eventually gives birth to a boy. The child delights his grandparents, and his laughter tricks the elder gods into revealing where they hide a shining ball of light. The gods give the child the ball to play with, and then Raven transforms back to a bird and flies off carrying the ball of light in his beak. He hangs the ball—the sun—in the sky, thereby bringing light to the world.6 Coyote's character is similar to that of Raven, and both appear in stories carrying out similar roles. In several stories from the American Southwest, Coyote steals fire from a group of "fire beings" and gives it to humans. In some tales Coyote wants to make human life more interesting, so he introduces sickness, sorrow, and death. He often teaches through negativeexample by employing the human vices of lying, cheating, and stealing. His tricks often bring about destructive natural phenomena, such as a great flood that destroys the earth. However, by causing the flood, Coyote leads the human race to a new and better world. Coyote shows us that at the heart of the trickster is a savior whose great gift to humans is showing them new ways of knowing and doing.Glossary:mischief: tendency to play tricks or cause minor troublethievery: the act of theft; stealingpinyon seed: the seed of a pine tree; pine nut第1题The word maliciously in paragraph 1 is closest in meaning toA.destructivelyB.falselyC.bravelyD.mistakenly第2题Which sentence below best expresses the essential information in the highlighted sentence in paragraph 1 ?

Dada was based on the principles of deliberate irrationality, disorder, and anarchy. Dada protested all forms of authority and convention. It rejected laws of beauty and social organization and attempted to discover authentic reality through the destruction of traditional culture and aesthetic forms. In Dada there was only one rule: Never follow any established rules. There was no predominant medium; however, assemblage, collage, and photomontage were techniques frequently employed. Dadaist art was nonsensical, impulsive, and often playful. The movement's founders included the French artist Jean Arp and the writers Tristan Tzara and Hugo Ball. At a meeting of young artists in 1916 in Zurich, one of them inserted a paper knife into a French-German dictionary. The knife pointed to the word dada, a French baby-talk word for a hobby-horse, which the group saw as an appropriate term for their anti-art.2 Dada emerged from despair over the First World War and disgust for the conservative values of society. Dada was the first expression of protest against the war. Dadaists used absurdity to create artworks that mocked society yet defied intellectual analysis, such as the use of "found" objects in sculptures and installations. The forerunner of the Dadaists, and ultimately their leading member, was Marcel Duchamp, who in 1913 created his first "ready-made," the Bicycle Wheel, consisting of a wheel mounted on the seat of a stool. In his effort to discourage aesthetics, Duchamp shocked the art establishment with these ready—mades—manufactured objects that he selected and exhibited—including a bottle rack and a comb. The Dada movement extended to literature and music and became international after the war. In the United States themovement was centered in New York City. Dadaists on both sides of the Atlantic had one goal in common: to demolish current aesthetic standards.3 Fifty years after the Dadaists, another generation of artists reacted to the standards and values of society. However, instead &rejecting ordinary things, the young artists of the Pop movement of the 1960s embraced them. Pop artists were curious about the commercial media of ads, billboards, newsprint, television, and all aspects of popular culture. Thus, the barrier between "high" and "low" art collapsed, which the Dadaists had aimed for and the Pop artists attained with an energy not seen before.4 Pop art received its name from critic Lawrence Alloway, who considered Pop to be the culture of the mass media, photographs, and posters—a style that must be popular, transitory, and witty. The subject matter of Pop art was derivative, depicting something that had already been published or produced, such as comic strips, soft-drink bottles, and photographs of movie stars. Pop art caught on quickly; it was art about mass consumption that was eagerly consumed by the masses.5 The most popular of the Pop artists was the painter Roy Lichtenstein. Lichtenstein painted enlarged copies of the least "arty" things he could find: romance and adventure comic strips. He was the first American artist to react to comic strips, finding beauty in these crude designs, along with a distinct sense of style. Lichtenstein also painted other pictorial styles, including blowups of other artists' brushstrokes and parodies of Cubism and Art Deco.6 Andy Warhol, more than any other Pop artist, took on the mind-numbing overload of American mass culture. Warhol began his career as a commercial illustrator, and in 1962 he had his first exhibition in an art gallery, where he showed his 32 Campbell's Soup Cans. The thirty-two soup cans are about sameness: same brand, same size, same paint surface, and same fame. They mimic the condition of mass advertising. All of Warhol's work flowed from one central insight: mass culture is filled with images that become meaningless by being repeated again and again, and in this glut of information is a role for art. Warhol felt this and embodied it. He conveyed a collective state of mind in which celebrity—a famous brand name or the image of a famous person—had completely replaced sacredness in art.Glossary:aesthetic: relating to beauty; artistic第13题According to the passage, the main goal of the Dada movement was toA.stimulate public interest in artB.change the goals of art educationC.destroy traditional standards of artD.make mass media the subject of art第14题The author mentions a hobby-horse in paragraph 1 in order toA.explain the origin of the name "Dada"B.illustrate how Dadaists created artpare art to a children's gameD.give an example of a "ready-made"第15题According to the passage, one way in which the Dadaists mocked society was byA.refusing to fight in the First World WarB.writing plays about social classing "found" objects in works of artD.criticizing the commercial media第16题The word forerunner in paragraph 2 is closest in meaning toA.leading writerB.earliest artistC.main criticD.fastest runner第17题The passage gives all of the following as examples of "ready-mades" EXCEPTA.a bicycle wheelB.a bottle rackC.a soup canD.a comb第18题The word embraced in paragraph 3 is closest in meaning toA.mockedB.ignoredC.welcomedD.defended第19题It can be inferred from paragraph 3 that the Pop artistsA.reacted against the Dada movementB.were more popular than the DadaistsC.criticized art for being too commercialD.succeeded in changing ideas about art第20题Which sentence below best expresses the essential information in the highlighted sentence in paragraph 4?

When large numbers of Europeans began to arrive in the eighteenth century, almost one-third of that area was covered with old-growth forests. In the eastern half of the continent, nearly 90 percent of the land was thick with forests of elm, ash, beech, maple, oak, and hickory. By the end of the nineteenth century, after several decades of intensive deforestation, only half of the original forests remained.2 During the first two centuries of European colonization, settlement was concentrated along the East Coast, having almost no effect on the vast forests covering the continent. Then, in the first half of the nineteenth century, agriculture expanded and settlers began to move westward in search of land for new farms. Land for agriculture came almost exclusively from clearing forests. The demand for farmland and timber continued to soar, and by 1850, more than 100 million acres of old-growth forest had been cut or burned off in the Northeast, the Southeast, the Great Lakes region, and along the St. Lawrence River.3 Along with agriculture, industrialization was a major cause of deforestation. The Industrial Revolution was fueled by North America's abundance of wood, as iron makers relied on charcoal, or charred wood, to fire their furnaces. Hardwoods such as oak produced the best charcoal, which charcoal burners made by slowly burning logs in kilns until they were reduced to concentrated carbon. It took eight tons of wood to make two tons of charcoal to smelt one ton of iron. Thus, the toll on the forests was high, as countless acres were cut to feed the furnaces of the iron industry.4 The transportation technology of the Industrial Revolution contributed greatly to deforestation. The river steamboats that came into operation after 1830 had a voracious appetite for wood. To keep their wheels turning, steamboats typically took on fuel twice a day. The wood was supplied by thousands of "wood hawks" along the banks of the Ohio and Mississippi with stacks of cut firewood. Annual consumption of wood on riverboats continued to increase until 1865. Consequently, river valleys that had the heaviest traffic were stripped of their forests.5 After 1860, immigration and westward expansion surged, and railroads swept over the continent. Clean-burning hardwood was the preferred fuel of the "iron horses," which required the cutting of 215,000 acres of woodland to stay in operation for one year. Not only did wood fuel the steam engines, but enormous amounts of oak and locust also went into the manufacture of railcars, ties, fencing, bridges, and telegraph poles. Railroads in the United States and Canada stretched from coast to coast by 1885, and each additional mile of railroad meant at least two more miles of fencing and 2,500 ties.6 Other major consumers of forest products included ordinary homeowners. More than four out of five of the houses constructed in the early nineteenth century—from log cabins to clapboard cottages—were built mainly of wood and roofed with wooden shingles. All were filled with wooden furniture. Two-thirds of all households in North America were heated by open, wood-burning fireplaces, and it took between 10 and 20 acres of forest to keep a single fireplace burning for one year.7 Throughout the century, the timber industry continued to supply the single most valuable raw material for a rapidly expanding population. Between 1840 and 1860, the annual production of lumber rose from 1.6 million to 8 billion board feet. This increase was made possible by the widespread application of steam power. Wood-fueled steam engines powered the sawmills, moved and barked the logs, and finished the boards. Railroad lines were now built right into the forests so that felled logs could be shipped directly to market. These innovations had their greatest impact on the Great Lakes region. By 1890 the technology of the timber industry had triumphed over the natural abundance of the forests, and woodlands that had once seemed endless were now depleted.第26题The word thick in paragraph 1 is closest in meaning toA.flatB.denseC.humidD.open第27题What point does the author make about deforestation in North America?A.It occurred mostly within a single century.B.It changed how people thought about trees.C.It provided jobs in several related industries.D.It caused an economic crisis in two countries.第28题According to the passage, all of the following contributed to deforestation EXCEPTA.the expansion of agricultureB.an increase in forest firesC.the use of charcoal as a fuelD.steamboat transportation第29题Why does the author use the word toll in discussing the iron industry in paragraph 3?A.To show that the process of smelting iron was expensiveB.To illustrate the impact of forest fires on the iron industryC.To point out that the iron industry had to pay high taxesD.To emphasize that large areas of woodland were eliminated第30题The word voracious in paragraph 4 is closest in meaning toA.varyingB.greedyC.strangeD.moderate第31题The phrase "wood hawks" in paragraph 4 describesA.a type of riverboatB.a species of treeC.people who sold woodrge woodland birds第32题The word surged in paragraph 5 is closest in meaning toA.stoppedpetedC.fluctuatedD.increased第33题It can be inferred from paragraph 5 that "iron horses" wereA.machines that made ties and fencingB.railroad company executivesC.steam engines that moved trainsD.animals that helped build railroads第34题Which sentence below best expresses the essential information in the highlighted sentence in paragraph 6?

However, many adults do not get the recommended eight hours of sleep each night. The average adult today gets only 6.4 hours of sleep, nearly an hour and a half less than what the average person received a century ago. Only in recent years have health professionals begun to realize the prevalence and severity of sleep deprivation in the working population. A significant number of people work at night, work long shifts, or suffer from insomnia or jet lag. Others are deprived of sleep because they work toohard, stay out too late, or try to do too many things in a day. Adults who regularly sleep six hours or less might think they accomplish more by staying up late, but they pay for it the next day when they feel sleepy or irritable or are unable to concentrate, remember things, or be very effective at their work.2 Studies show that the brain is adversely affected by sleep deprivation because certain patterns of electrical and chemical activity that occur during sleep are interrupted and the brain cannot function normally. In one study, thirteen healthy adult subjects who usually had normal sleep patterns were kept awake and carefully monitored in a hospital sleep laboratory during a period of 35 hours. During the experiment, the subjects were asked to perform several cognitive tasks, such as arithmetic and word problems, while undergoing magnetic resonance scans of their brain activity. The scans recorded each subject's brain activity from a rested state through various stages of sleep deprivation over the 35-hour period. The scans produced images showing increased activity in some regions of the brain and decreased activity in others. The researchers found that the temporal lobe of the brain, the region involved in language processing, was activated during verbal tasks in rested subjects but not in sleep-deprived subjects. When subjects were fully rested, their magnetic resonance scans showed that the temporal lobe was very active. However, after several hours without sleep, there was no activity within this region. The effects of the inactivity included slurred speech in the subjects who had gone for prolonged periods with no sleep.3 Several studies show that getting fewer than six hours of sleep a night can impair short-term memory, coordination, reaction time, and judgment—thus posing a serious risk of accident or injury. In one study of drivers, researchers reported that sleep deprivation had some of the same hazardous effects as being drunk. They found that people who drove after being awake for 17 to 19 hours performed worse than those with a blood alcohol level of 0.05 percent, the legal limit for drunk driving in most western European countries. The study also found that 16 to 60 percent of road accidents involved sleep deprivation. The researchers concluded that countries with drunk driving laws should consider similar restrictions against sleep-deprived driving.4 There are other problems associated with sleep deprivation beyond impaired motor skills and judgment. Drivers who get too little sleep may have higher levels of stress, anxiety and depression, may take unnecessary risks, or may express rage toward other drivers. These dangers affect not only drivers but also people who work long shifts or night shifts, such as medical personnel and other emergency workers. The dangers of sleep deprivation go far beyond the obvious risks and can, in fact, undermine all areas of an individual's physical and mental health.5 Sleep deprivation weakens the immune system, making an individual more prone to diseases such as the common cold and diabetes. Without sleep, the number of disease-fighting white blood cells within the body decreases, as does the activity of the remaining white blood cells. Sleep deprivation has been linked to a decrease in the body's production of hormones such as insulin. Results of a recent study suggested that healthy young adults who regularly got under 6.5 hours of sleep a night had greater insulin resistance than people who got 7.5 to 8.5 hours of sleep. Insulin resistance is a silent condition in which the pancreas does not make enough insulin or the body is unable to use the insulin that is present. Thus, the muscle and liver cells cannot metabolize the sugar called glucose. As a result, glucose builds up in the bloodstream, setting the stage for diabetes and heart disease.。

Well, if you took oceanography, you’d need that mathematics course first. There would be some physics and chemistry, so you’d need a solid grasp of numerical data. M: That’s what I wanted to talk to you about. I thought, if I took the math course at the same time as oceanography, then I could graduate at the end of the year. W: Sorry, but you need to have the math course first. Unless you have a good foundation in math, you’ll find oceanography very difficult. M: I’ve taken three math classes already. Isn’t that enough? W: I’m afraid not. The Oceanography Department specifically requires Math 150. M: I wish I could convince someone! I know I could do both courses! Would it help if I talked to the professor? W: You could try, but I wouldn’t get my hopes up if I were you.M: Oh, well, in that case, I’d better just take the math course and get it over with. W: Good idea.

However, if advertisers still focused on that segment of the population, they would put themselves out of business. Only about ten percent of American families fit the stereotype, and households with working mothers and singles are on the rise. If advertising is to be successful, it has to identify the potential users of a product and aim its message toward that group.2 An advertising agency can decide on the best way of reaching potential buyers only if it conducts market research to understand who they are. Are they homemakers or professional people? Are they young or old? Do they live in the city, the country, or the suburbs? Unless the agency obtains detailed data and marketing expertise, the advertising campaign will face failure.36．Why does the author say they would put themselves out of business in paragraph 1?A．To explain what advertisers did in the pastB．to complain about false advertisingC．To identify the main fear of advertisersD．To show that advertisers have changed what they do正确答案：D解析：The author’s purpose is to show that advertisers have changed what they do. The present unreal conditional sentence states an untrue condition, if advertisers still focused on that segment of the population, meaning that advertisers do not still focus on the same population. 知识模块：阅读37．The author believes that advertisers today should do all of the following EXCEPTA．focus on the traditional familyB．identify potential buyersC．conduct researchD．obtain marketing expertise正确答案：A解析：The author does not believe that advertisers should focus on the traditional family. All of the other answers are given: ...it has to identify the potential users of a product...; ...only if it conducts market research...; Unless the agency obtains detailed data and marketing expertise.... 知识模块：阅读38．Which sentence below best expresses the essential information in the highlighted sentence in paragraph 2?A．Before doing any research, advertisers must decide who the buyers are.B．The best way to reach potential buyers is to find out where they live and work.C．Advertisers must know their potential buyers in order to reach them effectively.D．There are many creative ways for conveying a message to potential buyers.正确答案：C解析：Advertisers must know their potential buyers... is a paraphrase of ...only if it conducts market research to understand who they are. ...in order to reach them effectively is a paraphrase of An advertising agency can decide on the best way of reaching potential buyers.... 知识模块：阅读SPEAKINGSpeaking QuestionDirections: In this question, you will listen to a conversation.

W: Well, as long as you’re going to the fair, would you take notes for me? I mean, let me know about anything in civil engineering, and pick up any handouts? M: Sure, I could do that.

托福模拟试卷42(题后含答案及解析)题型有：1. Listening Comprehension 3. Reading Comprehension 4. SPEAKING 5. WRITINGSection One：Listening Comprehension听力原文：NarratorListen to part of a lecture in a psychology class. ProfessorOK, uh let’s um, let’s start. All Jim Abbott ever wanted to do...uh... was play baseball. This is not an unusual ambition, perhaps, but Jim Abbott was born with a condition that might have dampened the motivation of most others: He has no...uh...no right hand. You’d never know it watching him pitch in the Majors, though(he’s currently with the Angels). What would motivate a young man to pursue a goal that everyone told him was impossible? The words motivation and emotion...uh...both come from the Latin root meaning “move”, and the psychology of motivation is indeed the study of what...what moves why we do what we do. Like emotion, motivation involves physiological processes, cognitive processes, and social and cultural processes that shape its expression. Emotion can motivate us to behave in particular ways: Anger can move us to shout, fear can move us to run, and love moves ...um to do all sorts of things. But emotion is only one kind of motivating force. In general, motivation refers to...to an inferred process within a person or animal that causes the organism to move toward a goal. The goal may be to satisfy a biological need, as in eating a sandwich to reduce hunger. The goal may be to fulfill a psychological ambition, such as...as...discovering a vaccine for AIDS or winning a Nobel Prize. But psychologists who study motivation, like those who study emotion, often disagree about what the phenomenon is, what causes it, and how to identify it. If you...uh...see a woman eating a doughnut, you don’t necessarily know her motive for doing so. Perhaps she is ravenously hungry and could eat anything you put in front of her? perhaps she has an insatiable passion for doughnuts and will eat one even if she has just consumed a five-course meal; perhaps she hates doughnuts but is being polite because a friend brought her one as a surprise. Moreover, just as several emotions usually cluster together, so several motives may...may operate together, sometimes...uh...in different directions. A man may be motivated to achieve financial success and to be a good father, but what happens when one motive conflicts with the other? For many decades, the study of motivation was dominated by drive theory put forward by Hull in 1943. In drive theory, biological needs result from states of physical deprivation, such as a lack of food or water. Such needs create a...a physiological drive, a state of tension that motivates an organism to satisfy the need. We have only a few primary(unlearned)drives, including hunger, thirst, excessive cold and pain. Although physical energy fuels most human motives, it soon became apparent that drive theory could not account for the complexity and variety of human motivations. As drive theory went out of fashion, so did the field of motivation as amajor topic in psychology. Recently, uh...however, research on motivation has been reinvigorated by the “cognitive revolution”- the emphasis throughout psychology on the fact that people are conscious creatures who think and plan ahead, who set goals for themselves and plot strategies to reach them. Modern motivational research tends to emphasize what is unique in human aspirations such as the pursuit of fame, romantic love, athletic perfection, or a seemingly impossible goal such as rowing across the ocean. These social motives(in contrast to biological drives)are learned, some in childhood, some in later life, and they are called “social” because they develop in the context of family, environment, and culture. We now focus on one of the domains of adult life that we think best illustrate the cognitive and biological complexities of human social motivation; love. OK...the need for affiliation refers to the motive to be with others, to make friends, to cooperate, to love. Our lives would be impossible without connection to others. Human development depends on the child’s ability to form attachments and to learn from adults and peers, and on the adult’s ability to form relationships with intimate partners, family, friends, and colleagues. No one doesn’t need someone. Of course, individuals vary in their need for affiliation; some like “lots of space” and “breathing room”, and others like to be surrounded by friends and family every minute of the day. Cultures, too, vary in the value they place on affiliation. American culture emphasizes independence and self-reliance, but Latino and Asian cultures emphasize family cohesiveness, group interdependence, arid teamwork. In the United States “dependence” is almost a dirty word, but in Japan the need for dependence is assumed to be powerful and necessary. In reality, all individuals are dependent; but they often depend on one another for different things at different ages.Now get ready to answer the questions. You may use your notes to help you answer.1. Why does the professor mention Jim Abbott?2. According to the professor, what is motivation?3.

In 1886, a French zoologist put a tiny leaf-shaped saltwater fish into a tank in his laboratory. The fish, about four centimeters long, startled the scientist when it turned into a tiny eel—long, rounded, and clear as window glass. Ten years later, another zoologist observed the same metamorphosis in the Mediterranean Sea and concluded that salt water was important to the process. In 1920, Danish biologist Johannes Schmidt tracked eels in the Atlantic Ocean, eventually finding individuals of the smallest size in the Sargasso Sea, an area of the North Atlantic between the West Indies and the Azores that is approximately 1,100 kilometers wide and 3,200 kilometers long and surrounded by four major ocean currents.2 Atlantic eels have five life phases: larva, glass eel, elver, immature yellow eel, and mature silver eel. Eels are catadromous fish, living most of their lives in fresh water and then migrating to the sea to reproduce. Their migration is an epic life journey, north through the Atlantic, toward the shore, into rivers and lakes, and eventually back to the Sargasso Sea, swimming in the open water by night. Scientists have not yet fully documented adult eels arriving at the Sargasso, or eels mating or laying eggs there, but they have observed the newly hatched larvae clustering in the floating Sargassum weed. The tiny larvae rise to the surface, where they begin their journey by drifting on the Gulf Stream toward either North America or Europe. A year may pass before the young fish swim toward the shore and fresh water. As they approach the coast, the larvaetransform into transparent glass eels, five to seven centimeters in length. It is not yet known how the eels find their way inland, but once glass eels leave the ocean and enter fresh water, they swim upstream, eventually turning into thin, black, ten-centimeter elvers.3 As the elvers grow, they change into adolescent yellow eels, long and slender with brownish-yellow sides and bellies. Yellow eels spend the next several years in flesh water, living in rivers and lakes for up to twenty years. Nearly all of the eels in lakes are female, while those in rivers and estuaries are mainly male. As the adolescents mature into adults, their eyes grow larger, their backs darken, their sides become silver, and their bellies turn silver-white. They start changing into mature silver eels, ready to begin their southward migration to the Sargasso Sea in late autumn. The transformation into sexually mature fish occurs deep in the Atlantic, during the long swim back to their mating site.4 During their long migration, eels face numerous hurdles. Most of these are the result of human activity, such as the dams, weirs, and other physical impediments that have compromised many river systems. Young black elvers require help getting past dams as they migrate upstream. Because eels are able to breathe through their skin as well as their gills, they can travel over wet surfaces on land, so in some locations biologists have devised wet ramps to assist their climb. During their downstream journey, silver eels can be killed when they swim into the turbines of hydroelectric dams, and a river's entire eel run can be destroyed in just a few nights. To combat the problem, some energy companies slow the rotation of the blades during the migration so that the eels might pass safely through the turbines. Another hurdle to the eels' passage is the presence of ancient eel weirs, structures of various types built by every human culture that ever inhabited the region. Natural predators also take a toll: eagles, osprey, snapping turtles, and bass all feed on eels.5 Overfishing and exploitive fisheries have caused eel populations to plummet. Fisheries target eels at three phases of their lives. Before the tiny glass eels can reach shore, thousands are trapped in nets for export to fish farms in Asia. Yellow eels are caught in eel pots for bait, and silver eels are caught in traps for specialty markets around the world. In addition to overfishing, eels will face a more serious threat if climate change alters the speed or direction of the currents around the Sargasso Sea. Even a slight shift in the currents would impact the mating and hatching territories of the Atlantic eel.第30题The word metamorphosis in paragraph 1 is closest in meaning toA.type of movementB.change in appearanceC.swimming abilityD.reduction in size第31题What is the main purpose of paragraph 1?A.To introduce the phenomenon of the eel's life phasesB.To contrast the discoveries of three scientistsC.To entertain readers with scientific mysteriesD.To emphasize the eel's need for both salt and fresh water第32题According to the passage, one characteristic that defines catadromous fish isA.their ability to navigate by smellB.their very long life spanC.their preference for a diet of Sargassum weedD.their migration from fresh water to salt water第33题Scientists have direct evidence of which eel behavior in the Sargasso Sea?rvae swimming among the plantsB.Glass eels transforming into elversC.Adolescents becoming adultsD.Adult females dying after laying eggs第34题The word drifting in paragraph 2 is closest in meaning toA.feedingB.strugglingC.hatchingD.riding第35题According to paragraph 2, there is scientific uncertainty aboutA.where the eels go to reproduceB.what the newly hatched eels eatC.how the eels locate fresh waterD.when the eels become black in color第36题One difference between eels living in rivers and those living in lakes isA.the color of their backs, sides, and belliesB.the level of competition with other speciesC.the season in which their migration beginsD.the relative numbers of females and males第37题Which sentence best expresses the essential information in the highlighted sentence in paragraph 4?

Over one million residents lived in extreme poverty, with 300,000 of them packed into one square mile alone. Most were immigrants from Europe and Asia. Men, women, children, and the elderly all worked for low wages in the thousands of sweatshops that made clothing, cigars, furniture, and tinware. Few of the realist painters of the time wanted to paint this New York; it was a photographer and writer, Jacob Riis, who opened the subject to a wide public.2 Jacob Riis was born in Denmark and immigrated to the United States in 1870, at the age of twenty-one. He landed in New York and got a job as a police court reporter for the New York Tribune. The police headquarters was located in the heart of the East Side slum district, and Riis came to know thousands of the local poor. What he saw inspired him to fight for the elimination of slums using the tools of journalism. At that time, American journalism was changing. The urban population was multiplying rapidly, and there was an explosion of newspapers. The papers aimed to reach larger audiences, which led them to increase the number of human-interest stories—stories not just about the comfortable classes, but about the "other half" and how it lived.3 Jacob Riis became New York's chief reporter of urban blight, making a name for himself with his detailed accounts of life in the Lower East Side. Today he is best known as a photographer. In the 1880s, photography was still at an early stage, and news photos were rare. As a good journalist, Riis was quick to see that recent developments in flashlight photography would enable him to dramatize his stories. Photography would be his means for drawing attention to the living conditions of the poor, particularly the immigrant population. He committed himself to this cause, knowing that the affluent and educated half of society could not ignore photographs of how the other half lived.4 In 1890 he published his photographs in a book, How the Other Half Lives, his most famous work. The book was a bestseller and ran through several editions. The photographs exposed the appalling conditions of the time and were direct evidence of human misery in the immigrant enclaves, back alleys, and cheap lodging houses. Shocked readers saw images of ragged children playing in the street and old people toiling in dim sweatshops. They were horrified by the miserable existence of a million people, the powerless and destitute of America's "other half."5 Riis was a member of the new generation of "muckraking" journalists that investigated corruption, injustice, exploitation, and poverty. Like the other muckrakers, Riis made it his mission to seek out and expose the darker side of society. By today's standards of journalisticetiquette, he was very intrusive, feeling no need to get permission from his subjects before photographing them. Riis and his assistants would burst into tenements and saloons, startling people with their cameras and flashlights. Many of the photographs were taken at night, requiring artificial lighting, which at the time consisted of flash cartridges fired from a revolver into a frying pan. The explosive noise caused terror and confusion. On two occasions, Riis accidentally set fire to rooms he was photographing when the flash cartridge exploded in flames.6 Still, as a journalist and photographer, Jacob Riis had more of an influence on reforming living conditions than did any of the more conventional social workers of his day. One day Riis received a note that read, "I have read your book and I have come to help." The note was from the head of the New York Police Board of Commissioners, Theodore Roosevelt, who later went on to become president of the United States. Moved by the photographs Riis had taken, Roosevelt instituted a number of social reforms. The photographs in How the Other Half Lives are still prized for their historic value and stand out as proof of the power of pictures to bring about social change.第44题Why does the author describe New York's Lower East Side in paragraph 1?A.To identify the place with the world's highest concentration of peopleB.To illustrate the rapid growth of New York in the nineteenth centuryC.To argue for better wages for people working in sweatshopsD.To provide the setting and subject of Jacob Riis's photographs第45题Which sentence below best expresses the essential information in the highlighted sentence in paragraph 1?
