托福备考托福阅读34套TPO样题+解析+译文17--3 Symbiotic Relationships

托福考试 复习托福阅读TPO17(试题+答案+译文)第3篇:Symbiotic Relationships托福阅读原文【1】A symbiotic relationship is an interaction between two or more species in which one species lives in or on another species. There are three main types of symbiotic relationships: parasitism, commensalism, and mutualism. The first and the third can be key factors in the structure of a biological community; that is, all the populations of organisms living together and potentially interacting in a particular area.【2】Parasitism is a kind of predator-prey relationship in which one organism, the parasite, derives its food at the expense of its symbiotic associate, the host. Parasites are usually smaller than their hosts. An example of a parasite is a tapeworm that lives inside the intestines of a larger animal and absorbs nutrients from its host. Natural selection favors the parasites that are best able to find and feed on hosts. At the same time, defensive abilities of hosts are also selected for. As an example, plants make chemicals toxic to fungal and bacterial parasites, along with ones toxic to predatory animals (sometimes they are the same chemicals). In vertebrates, the immune system provides a multiple defense against internal parasites.【3】At times, it is actually possible to watch the effects of natural selection in host-parasite relationships. For example, Australia during the1940 s was overrun by hundreds of millions of European rabbits. The rabbits destroyed huge expanses of Australia and threatened the sheep and cattle industries. In 1950, myxoma virus, a parasite that affects rabbits, was deliberately introduced into Australia to control the rabbit population. Spread rapidly by mosquitoes, the virus devastated the rabbit population. The virus was less deadly to the offspring of surviving rabbits, however, and it caused less and less harm over the years. Apparently, genotypes (the genetic make-up of an organism) in the rabbit population were selected that were better able to resist the parasite. Meanwhile, the deadliest strains of the virus perished with their hosts as natural selection favored strains that could infect hosts but not kill them. Thus, natural selection stabilized this host-parasite relationship.【4】In contrast to parasitism, in commensalism, one partner benefits without significantly affecting the other. Few cases of absolute commensalism probably exist, because it is unlikely that one of the partners will be completely unaffected. Commensal associations sometimes involve one species' obtaining food that is inadvertently exposed by another. For instance, several kinds of birds feed on insects flushed out of the grass by grazing cattle. It is difficult to imagine how this could affect the cattle, but the relationship may help or hinder them in some way not yet recognized.【5】The third type of symbiosis, mutualism, benefits both partners in therelationship Legume plants and their nitrogen-fixing bacteria, and the interactions between flowering plants and their pollinators, are examples of mutualistic association. In the first case, the plants provide the bacteria with carbohydrates and other organic compounds, and the bacteria have enzymes that act as catalysts that eventually add nitrogen to the soil, enriching it. In the second case, pollinators (insects, birds) obtain food from the flowering plant, and the plant has its pollen distributed and seeds dispersed much more efficiently than they would be if they were carried by the wind only. Another example of mutualism would be the bull's horn acacia tree, which grows in Central and South America. The tree provides a place to live for ants of the genus Pseudomyrmex. The ants live in large, hollow thorns and eat sugar secreted by the tree. The ants also eat yellow structures at the tip of leaflets: these are protein rich and seem to have no function for the tree except to attract ants. The ants benefit the host tree by attacking virtually anything that touches it. They sting other insects and large herbivores (animals that eat only plants) and even clip surrounding vegetation that grows near the tree. When the ants are removed, the trees usually die, probably because herbivores damage them so much that they are unable to compete with surrounding vegetation for light and growing space.【6】The complex interplay of species in symbiotic relationships highlights an important point about communities: Their structuredepends on a web of diverse connections among organisms.托福阅读试题1.Which of the following statements about commensalism can be inferred from paragraph 1?A.It excludes interactions between more than two species.B.It makes it less likely for species within a community to survive.C.Its significance to the organization of biological communities is small.D.Its role in the structure of biological populations is a disruptive one.2.The word derives in the passage (paragraph 2) is closest in meaning toA.DigestsB.ObtainsC.ControlsD.Discovers3.According to paragraph 2, which of the following is true of the action of natural selection on hosts and parasites?A.Hosts benefit more from natural selection than parasites do.B.Both aggression in predators and defensive capacities in hosts are favored for species survival.C.The ability to make toxic chemicals enables a parasite to find and isolate its host.rger size equips a parasite to prey on smaller host organisms.4.The word devastated in the passage (paragraph 3) is closest in meaning toA. InfluencedB.InfectedC.strengthenedD.destroyed5.Which of the following can be concluded from the discussion in paragraph 3 about the Australian rabbit population?A.Human intervention may alter the host, the parasite. and the relationship between them.B.The risks of introducing outside organisms into a biological community are not worth the benefits.C.Humans should not interfere in host-parasite relationships.anisms that survive a parasitic attack do so in spite of the natural selection process.6.According to paragraph 3, all of the following characterize the way natural selection stabilized the Australian rabbit population EXCEPT:A.The most toxic viruses died with their hosts.B.The surviving rabbits were increasingly immune to the virus.C.The decline of the mosquito population caused the spread of the virus to decline.D.Rabbits with specific genetic make-ups were favored.7.The word inadvertently in the passage (paragraph 4) is closest in meaning toA.IndefensiblyB.SubstantiallyC.UnintentionallyD.Partially8.According to paragraph 5, the relationship between legumes and bacteria benefits the soil byA.adding enriching carbohydratesB.speeding the decay of organic matterC.destroying enzymes that pollute itD.contributing nitrogen to it9.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage (paragraph 5)? Incorrect choices change the meaning in important ways or leave out essential information.A.The relationship between flowering plants and pollinators provides pollinators with food and flowers with efficient reproduction.B.In some cases birds obtain food from the seeds that are dispersed in the wind.C.The wind not only helps the flowers distribute their seeds but enablesbirds to find more food.D.Animals and insects are more effective in distributing pollen and seeds than the wind.10.According to paragraph 5, which of the following is NOT true of the relationship between the bull's horn acacia tree and the Pseudomyrmex ants?A.According to paragraph 5, which of the following is NOT true of the relationship between the bull's horn acacia tree and the Pseudomyrmex ants?B.The acacia trees are a valuable source of nutrition for the ants.C.The ants enable the acacia tree to produce its own chemical defenses.D.The ants protect the acacia from having to compete with surrounding vegetation.11.The word highlights in the passage (paragraph 6) is closest in meaning toA.DefinesB.EmphasizesC.ReflectsD.Suggests12.What is the main purpose of paragraph 6?A.To explain the concept of symbiosis by expanded descriptions of its principal typesB.To make a comparison between human relationships and symbiotic interactions in the natural worldC.To demonstrate the unforeseen benefits of natural processes that at first seem wholly destructiveD.To argue that parasitism is a problem that can be solved by scientific intervention13. Look at the four squares [■] that indicate where the following sentence could be added to the passage. Where would the sentence best fit? This massive population began a century earlier as a mere twelve pairs of imported rabbits that reproduced quickly and developed into a major problem.At times, it is actually possible to watch the effects of natural selection in host-parasite relationships. For example, Australia during the 1940 s was overrun by hundreds of millions of European rabbits. ■【A】The rabbits destroyed huge expanses of Australia and threatened the sheep and cattle industries. ■【B】In 1950, myxoma virus, a parasite that affects rabbits, was deliberately introduced into Australia to control the rabbit population. ■【C】Spread rapidly by mosquitoes, the virus devastated the rabbit population. ■【D】The virus was less deadly to the offspring of surviving rabbits, however, and it caused less and less harm over the years. Apparently, genotypes (the genetic make-up of an organism) in the rabbit population were selected that were better able to resist theparasite. Meanwhile, the deadliest strains of the virus perished with their hosts as natural selection favored strains that could infect hosts but not kill them. Thus, natural selection stabilized this host-parasite relationship.14. Directions: 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.Symbiotic relationships involve the interaction of two or more organisms acting as partners.A.Parasitic relationships involve the interplay of aggression by the parasite and resistance and adaptation by the host.B.Mutualism ordinarily involves an interaction between two members of the same species.C.Mutualism is unique among symbiotic relationships in that it r benefits both partners involved in the relationship.D.Parasitic damage to Australian rabbits was never reversed because the rabbits were unable to adapt to the parasites' attacks.E.The rarity of commensal relationships stems from the difficulty of finding relationships that benefit one species without affecting the other.F.The structure of biological communities depends on the types ofrelationships that exist among the species within.托福阅读答案1.以commensalism做关键词定位至第二句,说有三种类型,第一种和第三种很重要,根据对比,也就是说第二种commensalism不重要,所以答案是C。

托福备考托福阅读34套TPO样题+解析+译文30—3 The Invention of the Mechanical Clock

托福考试 复习TPO 30—3 The Invention of the Mechanical Clock原文:【1】In Europe, before the introduction of the mechanical clock, people told time by sun (using, for example, shadow sticks or sun dials) and water clocks. Sun clocks worked, of course, only on clear days; water clocks misbehaved when the temperature fell toward freezing, to say nothing of long-run drift as the result of sedimentation and clogging. Both these devices worked well in sunny climates; but in northern Europe the sun may be hidden by clouds for weeks at a time, while temperatures vary not only seasonally but from day to night.【2】Medieval Europe gave new importance to reliable time. The Catholic Church had its seven daily prayers, one of which was at night, requiring an alarm arrangement to waken monks before dawn. And then the new cities and towns, squeezed by their walls, had to know and order time in order to organize collective activity and ration space. They set a time to go to sleep. All this was compatible with older devices so long as there was only one authoritative timekeeper; but with urban growth and the multiplication of time signals, discrepancy brought discord and strife. Society needed a more dependable instrument of time measurement and found it in the mechanical clock.【3】We do not know who invented this machine, or where. It seems to have appeared in Italy and England (perhaps simultaneous invention) between 1275 and 1300. Once known, it spread rapidly, driving out water clocks but not solar dials, which were needed to check the new machines against the timekeeper of last resort.These early versions were rudimentary, inaccurate, and prone to breakdown. 【4】Ironically, the new machine tended to undermine Catholic Church authority. Although church ritual had sustained an interest in timekeeping throughout the centuries of urban collapse that followed the fall of Rome, church time was nature’s time. Day and night were divided into the same number of parts, so that except at the equinoxes, days and night hours were unequal; and then of course the length of these hours varied with the seasons. But the mechanical clock kept equal hours, and this implied a new time reckoning. The Catholic Church resisted, not coming over to the new hours for about a century. From the start, however, the towns and cities took equal hours as their standard, and the public clocks installed in town halls and market squares became the very symbol of a new, secular municipal authority. Every town wanted one; conquerors seized them as especially precious spoils of war; tourists came to see and hear these machines the way they made pilgrimages to sacred relics.【5】The clock was the greatest achievement of medieval mechanical ingenuity. Its general accuracy could be checked against easily observed phenomena, like the rising and setting of the sun. The result was relentless pressure to improve technique and design. At every stage, clockmakers led the way to accuracy and precision; they became masters of miniaturization, detectors and correctors of error, searchers for new and better. They were thus the pioneers of mechanical engineering and served as examples and teachers to other branches of engineering.【6】The clock brought order and control, both collective and personal. Its publicdisplay and private possession laid the basis for temporal autonomy: people could now coordinate comings and goings without dictation from above. The clock provided the punctuation marks for group activity, while enabling individuals to order their own work (and that of others) so as to enhance productivity. Indeed, the very notion of productivity is a by-product of the clock: once one can relate performance to uniform time units, work is never the same. One moves from the task-oriented time consciousness of the peasant (working on job after another, as time and light permit) and the time-filling busyness of the domestic servant (who always had something to do) to an effort to maximize product per unit of time.题目:1.Why does the author provide the information that "in northern Europe the sun may be hidden by clouds for weeks at a time, while temperatures vary not only seasonally but from day to night"?A.T o emphasize the variety of environments in which people used sun and water clocks to tell time.B.To illustrate the disadvantage of sun and water clocks.C.To provide an example of an area where water clocks have an advantage over sun clocks.D.T o counter the claim that sun and water clocks were used all over Europe.2.According to paragraph 2, all of the following are examples of the importance oftimekeeping to medieval European society EXCEPTA.the need of different towns to coordinate timekeeping with each other.B.the setting of specific times for the opening and closing of markets.C.the setting of specific time for the start and finish of the working day.D.the regulation of the performance of daily church rituals.3.According to paragraph 2, why did the medieval church need an alarm arrangement?A.The alarm warned the monks of discord or strife in the town.B.The church was responsible for regulating working hours and market hours.C.The alarm was needed in case fires were not put out each night.D.One of the church's daily rituals occurred during the night.4.The word "authoritative" in the passage(paragraph 2)is closest in meaning toA.actual.B.important.C.official.D.effective.5.The author uses the phrase "the timekeeper of last resort" to refer toA.water clocks.B.the sun.C.mechanical clocks.D.the church.6.The word "rudimentary" in the passage(paragraph 3)is closest in meaning toA.rare.B.small.C.impractical.D.basic.7.According to paragraph 4, how did the Catholic Church react to the introduction of mechanical clocks?A.Its used mechanical clocks through the period of urban collapse.B.It used clocks to better understand natural phenomena, like equinoxes.C.It tried to preserve its own method of keeping time, which was different from mechanical-clock time.D.It used mechanical clocks to challenge secular, town authorities.8.The word "installed" in the passage(paragraph 4)is closest in meaning toA.required.B.expected by the majority of people.C.standardized.D.put in place.9.It can be inferred from paragraph 5 that medieval clockmakersA.were able to continually make improvements in the accuracy of mechanical clocks.B.were sometimes not well respected by other engineers.C.sometimes made claims about the accuracy of mechanical clocks that were not true.D.rarely shared their expertise with other engineers.10.Paragraph 5 answers which of the following questions about mechanical clocks.A.How did early mechanical clocks work?B.Why did the design of mechanical clocks affect engineering in general?C.How were mechanical clocks made?D.What influenced the design of the first mechanical clock?11.The word "pioneers" in the passage isclosest in meaning toA.leaders.B.opponents.C.employers.D.guardians.12.According to paragraph 6, how did the mechanical clock affect labor?A.It encouraged workers to do more time-filling busywork.B.It enabled workers to be more task oriented.C.It pushed workers to work more hours every day.D.It led to a focus on productivity.13. Look at the four squares[■] that indicate where the following sentence can be added to the passage. Where would the sentence best fit? The division of time no longer reflected the organization of religious ritual.Ironically, the new machine tended to undermine Catholic Church authority. Although church ritual had sustained an interest in timekeeping throughout the centuries of urban collapse that followed the fall of Rome,church time was nature's time.■【A】Day and night were divided into the same number of parts, so that exceptat the equinoxes, days and night hours were unequal;and then of course the length of these hours varied with the seasons.■【B】But the mechanical clock kept equal hours, and this implied a new time reckoning.■【C】The Catholic Church resisted, not coming over to the new hours for about acentury.■【D】From the start, however, the towns and cities took equal hours as their standard, and the public clocks installed in town halls and market squares became the very symbol of a new, secular municipal authority. Every town wanted one; conquerors seized them as especially precious spoils of war;tourists came to see and hear these machines the way they made pilgrimages to sacred relics.14. Directions: 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.The introduction of the mechanical clock caused important changes to the society of medieval Europe.A.The increasing complexity of social and economic activity in medieval Europe led to the need for a more dependable means of keeping time than sun and water clocks provided.B.Because they were unreliable even in sunny climates, sun clocks and water clocks were rarely used in Europe, even before the invention of the mechanical clock.C.Before the mechanical clock, every city wanted a large number of timekeepersbecause more timekeepers allowed for better organization of collective activities.D.Soon after the invention of mechanical clocks, sun and water clocks became obsolete because mechanical clocks were far more accurate.E.Predators help maintain biological diversity by limiting populations of a dominant competitor species, thereby preventing that species from excluding others.F.The removal of sea stars reduces the diversity of the community in which they are predators, and is therefore a bad idea.答案:1.从第一段的第二句开始,原文列举了这两种device各种的缺点,最后一句前半句说它们work,后面but表转折,证明要说有些情况它们不能用。

Part I Reading Comprehension (40%) Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.

Passage A Last December’s earthquakes in the Iranian city of Bam took a huge death toll-roughly 40,000 people-largely because of the collapse of thousands of mud-brick buildings. If a group of researchers in India are successful, the next earthquake might not be as destructive. British and Indian engineers are developing earthquake-proof housing using a cheap, universal material: bamboo. They designed a model house built around waterproof bamboo-sheet roofing and bamboo-reinforced concrete walls. To test the structure, the engineers, sponsored by the U.K. Department of International Development, took it to the Earthquake Engineering and Vibration Research Center in Bangalore, which has a state-of-the-art earthquake simulator (模拟装置). The researchers shook the house with five successive 30-second pulses, being equal to 7.8 on the Richter(里氏) scale. The simulation was more than 10 time as violent as the Bam earthquake, yet the house emerged undamaged. “We didn’t even crack the paint,” says engineer Paul Follett, of Britain’s Timber Research and Development Association. By some estimates, more than a billion people already live in bamboo structures. The innovation lies in developing ways to exploit bamboo’s spring. Easily pre-built, fire resistant, and far lighter than steel, bamboo-based structures could be assembled in three weeks and last 50 years. At five dollars a square foot, they would last roughly half as much as brick-and-block constructions. Follett says the project will follow an “open source” model: “Whatever is developed is freely available for the common good.”

Most Americans are very conscious of their health and try to maintain a nutritious diet and daily routines to maintain good health. Yet, for many years the tobacco and liquor industries have tried to project the image of style and fashion for those who use their products. Most have learned, however, that the dangers caused to health by tobacco and alcohol can no longer be denied or ignored. The campaigns to alert the public to the evils of these two social drugs have been intense and effective. However, most people dislike being warned that they shouldn’t do something. It is a kind of psychological resistance. Yet, all tobacco and liquor products must now contain a warning on the package. The warning is simple, but the message is clear: smoking and drinking are hazardous to health. The wording may vary, but it is phrased in such a way as to draw the attention of the consumer to the danger. On TV all tobacco advertising is legally banned, and every ad in a magazine must display the warning. There are many public notices on trains and buses giving out the warning that smoking is linked to lung cancer and other lung and heart diseases. The warning against alcohol consumption is of a different kind. It goes out especially to women who are pregnant and anyone operating a car or electrical machinery. A pregnant woman can cause damage to her baby by drinking alcohol. Also anyone operating a machine runs the risk of an accident which could be fatal. Such warnings appear on all wine bottles and even an apparently harmless can of beer.
