2018年5月6日托福考试真题解析!
2018年5月6日托福考试真题解析！5月第一场托福听力还是不负众望的难出新高度快来看看都考了什么逆天的题目吧......阅读部分Reading1.动物灭绝有几个不同的理论来说猛犸象还是什么的大型动物为啥灭绝。
一是说人类捕猎导致，二是说气候变化导致水食物变少，最后又跳出一个人说在座的都是垃圾，都忽略了重要的一点，生态圈是环环相扣的，每一个小变化都会导致蝴蝶效应，所以是上述理论结合起来的结果，他的理论也弥补了上述理论的不足，比如理论一没有大量捕杀遗迹来支撑。
2.Economic Decline in Europe during the Fourteenth Century14世纪欧洲经济的衰退。
首先因为气温变低，虽然就低了那么几度，但是稍微一点温度的变化都会对农业产生很大的影响，由于气温低了影响了农业，农作物产量就会下降，农民的生活就变得很惨，于是就拿不出钱，农业不好，资本又少了。
然后因为东亚一个M帝国的崛起，M重视信仰轻视商业，因此欧洲向亚洲的贸易之路就逐渐衰退了，他们开始向大西洋和非洲发展。
3.Olmec culture在Mesopotamia area 发现了重要的ceremonial sites.东部high lands 有一些sacred precinct。
里面重要的art and architecture. Kunze axe的发现帮助确立了这是Olmec culture.一开始发现的时候，研究者就十分确定这属于Mesopotamia地区，但是因为既不属于埃及文明也不属于希腊文明，使得研究者困惑了很长时间其起源。
后来结合一系列其它文物的发现证明属于Olmec 文化。
而且我们今天所认为的Maya calendar 其实是Olmec人发明的。
Olmec culture存在一套表示文化的consistent code，例如Kunze axe 里面也运用的howling baby’s face 就一直沿用至今天，而期间没有发生太大的变化。
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.。

3月3日托福口语真题回忆：Task 1内容回忆：你是学校学生，学校报纸要增加栏目，给学生带来方便，选增加哪个推荐：local restaurant review，film，travel参考答案：If a section is going to be added in campus newspaper, I will recommend local restaurant review. Apparently, students will not only eat on campus. They also have interests to explore local restaurants. This new section canprovide a reference for them, and students can choose where to eat based on those descriptions and comments, which will bring a lot of convenience. What’s more, Ithink this can also strengthen the connection between local communities and students. Those restaurants can take advantage of this section to advertise and attract more students to visit them. They can modify their food or provide special meals for students, which will benefit both themselves and students.Task 2内容回忆：学校是否应该进行道德教育(moral values)参考答案：Of course school should give students education on moral values.The word “education” not only refers to academic content teaching but also includes helping students become kind and straight people. You may have heard stories about high intelligent criminals, and we don’t want our children become people like that. So it is necessary that school should teach children what’s right and what’s wrong. Besides, although parents may play an important role on teaching their kids moral values, schools also have obligations. Those parents have various identities or backgrounds and they may pay attention on different aspects of children’s growth, which will cause some bias. Only school can provide children a systematic education on moral values.Task 3阅读通知：学校要取消人少的 club原因 1：为了省钱原因 2：对社交没用听力态度：女生不同意原因 1. 不能省钱：学校本身给 club 花的钱就很少;原因 2. 人少的 club 更好：成员间的关系会更好Task 4 生物阅读 holiday paradox：人们对周围环境熟悉，感觉时间就过得慢;不熟悉就过得快。

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? Incorrect choices change the meaning in important ways or leave out essential information.A.Dams and weirs have improved river systems for humans and eels.B.Human activity has created hurdles that block the eels' river passage.C.Eels had few physical problems until humans changed the course of rivers.D.The effects of human activity have been both positive and negative.第38题The word combat in paragraph 4 is closest in meaning toA.documentB.studyC.reduceD.ignore第39题Paragraph 4 supports which of the following statements about eel migration?A.More eels die in the river part of their migration than in the ocean.B.Sometimes humans can help eels get past impediments in rivers.C.The original purpose of weirs was to assist eels in their migration.D.Natural predators pose the most serious threat to migrating eels.第40题The word plummet in paragraph 5 is closest in meaning toA.declineB.migrateC.evolveD.disappear第41题It can be inferred from paragraph 5 that the author most likely believes which of the following statements about Atlantic eels?A.A net is the most effective type of equipment for capturing eels.B.People are just beginning to appreciate eels as a source of food.C.Climate change could endanger the ability of eels to reproduce.D.Scientists may never know why eels migrate such long distances.第42题Look at the four squares, A, B, C, and D, which indicate where the following sentence could be added to the passage. Where would the sentence best fit?Female yellow eels can grow to more than a meter in length, over twice the length of the males.A 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 fresh 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.B As the adolescents mature into adults, their eyes grow larger, their backs darken, their sides become silver and their bellies turn silver-white.C They start changing into mature silver eels, ready to begin their southward migration to the Sargasso Sea in late autumn.D The transformation into sexually mature fish occurs deep in the Atlantic, during the long swim back to their mating site.第43题An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points. Atlantic eels are long, slender fish with many fascinatingqualities and an epic life journey.●●●Answer ChoicesA. Eels undergo changes in shape and color as they pass through five life phases from larva to adult.B. The Sargasso Sea is an ideal mating site for eels because of the four surrounding ocean currents.C. Eels have a very long adolescence and may spend up to twenty years as immature yellow eels in rivers and lakes.D.

Several factors threaten the survival of eels, including altered river systems, overfishing, and climate change.上一题下一题(44~56/共56题)阅读理解THE PHOTOGRAPHS OF JACOB RIIS1 In the late nineteenth century, New York's Lower East Side had the highest concentration of people in the world. 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?

【新东方】轻松直达90分！2016年托福（TOEFL）金牌课程火热开售中Matching the influx of foreign immigrants into the larger cities of the United States during the late nineteenth century was a domestic migration, from town and farm to city, within the United States. The country had been overwhelmingly rural at the beginning of the century, with less than 5 percent of Americans living in large towns or cities. The proportion of urban population began to grow remarkably after 1840, increasing from 11 percent that year to 28 percent by 1880 and to 46 percent by 1900. A country with only 6 cities boasting a population of more than 8,000 in 1800 had become one with 545 such cities in 1900. Of these, 26 had a population of more than 100,000 including 3 that held more than a million people. Much of the migration producing an urban society came from smaller towns within the United States, but the combination of new immigrants and old American “settlers“ on America"s "urban frontier" in the late nineteenth century proved extraordinary.The growth of cities and the process of industrialization fed on each other. The agricultural revolution stimulated many in the countryside to seek a new life in the city and made it possible for fewer farmers to feed the large concentrations of people needed to providea workforce for growing numbers of factories. Cities also provided ready and convenient markets for the products of industry, and huge contracts in transportation and construction —as well as the expanded market in consumer goods — allowed continued growth of the urban sector of the overall economy of the Untied States.Technological developments further stimulated the process of urbanization. One example is the Bessemer converter (an industrial process for manufacturing steel), which provided steel girders for the construction of skyscrapers. The refining of crude oil into kerosene, and later the development of electric lighting as well as of the telephone, brought additional comforts to urban areas that were unavailable to rural Americans and helped attract many of them from the farms into the cities. In every era the lure of the city included a major psychological element for country people: the bustle and social interaction of urban life seemed particularly intriguing to those raised in rural isolation.1. What aspects of the United States in the nineteenth century does the passage mainly discuss?(A) Technological developments(B) The impact of foreign immigrants on cities(C) Standards of living(D) The relationship between industrialization and urbanization2.
