2021年托福阅读PASSAGE 35试题及答案PASSAGE 35The observation of the skies has played a special part in the lives and cultures of peoples since the earliest of times. Evidence obtained from a site known as the Hole in the Rock, in Papago Park in Phoenix, Arizona, indicates that it might have been used as an observatory by a prehistoric people known as the Hohokam.The physical attributes of the site allow its use as a natural calendar/clock. The "hole" at Hole in the Rock is formed by two large overhanging rocks coming together at a point, creating a shelter with an opening large enough for several persons to pass through. The northeast-facing overhang has a smaller opening in its roof. It is this smaller hole that produces the attributes that may have been used as a calendar/clock. Because of its location in the shelter's roof, a beam of sunlight can pass through this second hole and cast a spot onto the shelter's wall and floor. This spot of light travels from west to east as the sun moves across the sky. It also moves from north to south and back again as the Earth travels around the Sun, the west-to-east movement could have been used to establish a daily clock, much like a sundial, while the north-to-south movement could have been used to establish a seasonal calendar.The spot first appears and starts down the surface of the wall of the shelter at different times of the morning depending on the time of the year. The spot grows in size from its first appearance until its maximum size is achieved roughly at midday. It then continues its downward movement until it reaches a point where it jumps to the floor of the shelter. As the Sun continues to move to the west, the spot continues to move across the shelter floor and down the butte, or hill, toward a group of small boulders. If a person is seated on a certain one of these rocks as the spot reaches it, the Sun can be viewed through the calendar hole. This occurs at different times in the afternoon depending on the time of year.1. What does the passage mainly discuss?(A) observations of the stars by ancient people(B) rock formations of Arizona(C) a site used by ancient people to measure time(D) the movement of the earth around the Sun2. The word "obtained" in line 2 is closest in meaning to(A) acquired(B) transported(C) covered(D) removed3. The word "attributes" in line 5 is closest in meaning to(A) changes(B) characteristics(C) locations(D) dimensions4. The word "its" in line 10 refers to(A) roof(B) beam(C) hole(D) spot5. The word "establish" in line 15 is closest in meaning to(A) create(B) locate(C) consult(D) choose6. Which of the following is NOT true of the spot of light?(A) It is caused by sunlight passing through a hole.(B) It travels across the roof of the shelter.(C) Its movement is affected by the position of the Sun.(D) It movement could have been used to estimate the time of day.7. From which of the following can be the time of year be determined?(A) The movement of the spot of light from west to east(B) The speed with which the spot of light moves(C) The movement of the spot of light from north to south(D) The size of the sport of light at midday8.

托福备考托福阅读34套TPO样题+解析+译文15--2MassExtinctions物种灭绝-
托福考试 复习托福阅读TPO15(试题+答案+译文)第2篇:Mass Extinctions物种灭绝托福阅读原文【1】Cases in which many species become extinct within a geologicallyshort interval of time are called mass extinctions. There was one such event at the end of the Cretaceous period(around 70 million years ago).There was another, even larger, mass extinction at the end of the Permianperiod (around 250 million years ago). The Permian event has attractedmuch less attention than other mass extinctions because mostly unfamiliar species perished at that time.【2】The fossil record shows at least five mass extinctions in which many families of marine organisms died out. The rates of extinction happeningtoday are as great as the rates during these mass extinctions. Many scientists have therefore concluded that a sixth great mass extinction iscurrently in progress.【3】What could cause such high rates of extinction? There are several hypotheses, including warming or cooling of Earth, changes in seasonal fluctuations or ocean currents, and changing positions of the continents. Biological hypotheses include ecological changes brought about by theevolution of cooperation between insects and flowering plants or of bottom-feeding predators in the oceans. Some of the proposedmechanisms required a very brief period during which all extinctions suddenly took place; other mechanisms would be more likely to have taken place more gradually, over an extended period, or at different timeson different continents. Some hypotheses fail to account for simultaneous extinctions on land and in the seas. Each mass extinctionmay have had a different cause.Evidence points to hunting by humansand habitat destruction as the likely causes for the current mass extinction.【4】American paleontologists David Raup and John Sepkoski, who have studied extinction rates in a number of fossil groups, suggest that episodes of increased extinction have recurred periodically, approximately every 26 million years since the mid-Cretaceous period. The late Cretaceous extinction of the dinosaurs and ammonoids was justone of the more drastic in a whole series of such recurrent extinction episodes. The possibility that mass extinctions may recur periodically hasgiven rise to such hypotheses as that of a companion star with along-period orbit deflecting other bodies from their normal orbits, making some of them fall to Earth as meteors and causing widespread devastation upon impact.【5】Of the various hypotheses attempting to account for the late Cretaceous extinctions, the one that has attracted the most attention inrecent years is the asteroid-impact hypothesis first suggested by Luis andWalter Alvarez. According to this hypothesis, Earth collided with an asteroid with an estimated diameter of 10kilometers, or with several asteroids, the combined mass of which was comparable. The force of collision spewed large amounts of debris into the atmosphere, darkeningthe skies for several years before the finer particles settled. The reducedlevel of photosynthesis led to a massive decline in plant life of all kinds,and this caused massive starvation first of herbivores and subsequentlyof carnivores. The mass extinction would have occurred very suddenly under this hypothesis.【6】One interesting test of the Alvarez hypothesis is based on the presence of the rare-earth element iridium (Ir).Earth’s crust contains very little of this element, but most asteroids contain a lot more. Debris throwninto the atmosphere by an asteroid collision would presumably containlarge amounts of iridium, and atmospheric currents would carry this material all over the globe. A search of sedimentary deposits that spanthe boundary between the Cretaceous and Tertiary periods shows that there is a dramatic increase in the abundance of iridium briefly and precisely at this boundary. This iridiumanomaly offers strong support forthe Alvarez hypothesis even though no asteroid itself has ever been recovered.【7】An asteroid of this size would be expected to leave an immense crater,even if the asteroid itself was disintegrated by the impact. The intenseheat of the impact would produce heat-shocked quartz in many types ofrock. Also, large blocks thrown aside by the impact would form secondarycraters surrounding the main crater.To date, several such secondary-craters have been found along Mexico’s Yucatan Peninsula, and heat shocked quartz has been found both in Mexico and in Haiti.A locationcalled Chicxulub, along the Yucatan coast, has been suggested as the primary impact site.托福阅读试题1.Paragraph 1 supports which of the following statements about mass extinctions?A.They take place over a period of 70 million years.B.They began during the Cretaceous period.C.They eliminate many animal species that exist at the time they occur.D.They occur every 250 million years.2.According to paragraph 2, scientists base their belief that a mass extinction is going on at present on which of the following?A.The speed with which mass extinctions are happening today is similarto the speed of past extinctions.B.The number of species that have died out since the last extinction eventis extremely large.C.Mass extinctions occur with regularity and it is time for another one.D.Fossil records of many marine species have disappeared.3.The word extended in the passage is closest in meaning toA.specific.B. unlimited.C.reasonable.D. long.4.According to paragraph 3, each of the following has been proposed asa possible cause of mass extinctions EXCEPTA.habitat destruction.B.continental movement.C.fierce interspecies competition.D.changes in Earth's temperature.5.Paragraph 3 supports which of the following ideas about mass extinctions?A.Scientists know the exact causes of most mass extinctions.B.Mass extinctions are unlikely to happen again in the future.C.Insects, flowering plants, and bottom-feeding predators in the oceanstend to be the first organisms to disappear during episodes of mass extinctions.D.Some mass extinctions occurred on land and in the seas at the sametime.6.Which of the sentences below best expresses the essential informationin the underlined sentence （Paragraph 4）in the passage? Incorrect choices change the meaning in important ways or leave out essential information.A.Based on their studies of extinction rates of numerous fossil groups, paleontologists David Raup and John Sepkoski have determined that mass extinctions occur about every 26 million years.B.David Raup and John Sepkoski studied extinction rates of numerous fossil groups and suggest that mass extinctions during the Cretaceousperiod continued for 26 million years.C.Studies that paleontologists David Raup and John Sepkoski conductedof various fossil groups have revealed that extinction rates have increasedover the past 26 million years.D.The studies conducted by paleontologists David Raup and John Sepkoski of the fossil remains of species suggest that the extinction rateof species started to increase by the middle of the Cretaceous period.7.According to paragraph 4, what aspect of extinction episodes does the companion-star hypothesis supposedly clarify?A.Their location.B.Their frequency.C.Their duration.D.Their severity.8.The phrase account for in the passage(Paragraph 5)is closest in meaning toA.describe.B.challenge.C.explain.D.test.9.According to paragraph 6, what made iridium a useful test of the Alvarez hypothesis?A.Its occurrence in a few locations on Earth against several locations onother planets.B.Its occurrence in limited quantities on Earth against its abundance in asteroids.C.Its ability to remain solid at extremely high temperatures.D.Its ease of detection even in very small amounts.10.In stating that no asteroid itself has ever been recovered, the author emphasizes which of the following?A.The importance of the indirect evidence for a large asteroid.B.The fact that no evidence supports the asteroid impact hypothesis.C.The reason many researchers reject the Alvarez hypothesis.D.The responsibility of scientists for not making the effort to discover theasteroid itself.11.The word intense（Paragraph 7）in the passage is closest in meaningtoA.sudden.B.unusual.C.immediate.D. extreme.12.What is the purpose of paragraph 7 in the passage?A.It proposes a decisive new test of the Alvarez hypothesis.B.It presents additional supporting evidence for the Alvarez hypothesis.C.It explains why evidence relating to the Alvarez hypothesis is hard tofind.D.It shows how recent evidence has raised doubts about the Alvarez hypothesis.13. Look at the four squares [■] that indicate where the following sentence could be added to the passage. Where would the sentence bestfit? In general, it is believed that these two extinctions resulted from drastic environmental changes that followed meteorite impacts or massive volcanic eruptions.■Cases in which many species become extinct within a geologically shortinterval of time are called mass extinctions. ■There was one such eventat the end of the Cretaceous period (around 70 million years ago). ■There was another, even larger, mass extinction at the end of the Permian period (around 250 million years ago). ■The Permian event has attracted muchless attention than other mass extinctions because mostly unfamiliar species perished at that time.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 theyexpress ideas that are not presented in the passage or are minor ideas inthe passage. This question is worth 2 points.There have been many attempts to explain the causes of mass extinctions.A.Asteroid impacts, evolutionary developments, and changes in Earth'sclimate and in the positions of the continents have all been proposed aspossible causes of mass extinctions.B.Researchers have observed 26-million-year cycles in extinction rates ofa number of fossil groups that could all be attributed to the same cause.C.According to the Alvarez hypothesis, much of the iridium originally present on Earth was thrown into the atmosphere as a result of an asteroid impact that also caused a mass extinction.D.The unusual distribution of iridium on Earth and the presence of cratersand heat-shocked quartz are central to the theory that an asteroid impactcaused the late Cretaceous event.E.The collision between Earth and a large asteroid resulted in massive damage and generated enough heat to cause irreversible changes inEarth's atmosphere.F.There was a particularly large mass extinction that occurred around 250million years ago at the end of the Permian period, whose cause couldnot be determined.托福阅读答案1.以mass extinctions做关键词定位至第一句，说大量生物在短时间内灭绝的这种现象叫做大灭绝事件，C是原文的同义替换，所以是正确答案。

▉托福TPO15阅读Passage1原文文本： A Warm-Blooded Turtle When it comes to physiology, the leatherback turtle is, in some ways, more like a reptilian whale than a turtle. It swims farther into the cold of the northern and southern oceans than any other sea turtle, and it deals with the chilly waters in a way unique among reptiles. A warm-blooded turtle may seem to be a contradiction in terms. Nonetheless, an adult leatherback can maintain a body temperature of between 25 and 26°C (77-79°F) in seawater that is only 8°C (46.4°F). Accomplishing this feat requires adaptations both to generate heat in the turtle’s body and to keep it from escaping into the surrounding waters. Leatherbacks apparently do not generate internal heat the way we do, or the way birds do, as a by-product of cellular metabolism. A leatherback may be able to pick up some body heat by basking at the surface; its dark, almost black body color may help it to absorb solar radiation. However, most of its internal heat comes from the action of its muscles. Leatherbacks keep their body heat in three different ways. The first, and simplest, is size. The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape. An adult leatherback is twice the size of the biggest cheloniid sea turtles and will therefore take longer to cool off. Maintaining a high body temperature through sheer bulk is called gigantothermy. It works for elephants, for whales, and, perhaps, it worked for many of the larger dinosaurs. It apparently works, in a smaller way, for some other sea turtles. Large loggerhead and green turtles can maintain their body temperature at a degree or two above that of the surrounding water, and gigantothermy is probably the way they do it. Muscular activity helps, too, and an actively swimming green turtle may be 7°C (12.6°F) warmer than the waters it swims through. Gigantothermy, though, would not be enough to keep a leatherback warm in cold northern waters. It is not enough for whales, which supplement it with a thick layer of insulating blubber (fat). Leatherbacks do not have blubber, but they do have a reptilian equivalent: thick, oil-saturated skin, with a layer of fibrous, fatty tissue just beneath it. Insulation protects the leatherback everywhere but on its head and flippers. Because the flippers are comparatively thin and blade-like, they are the one part of the leatherback that is likely to become chilled. There is not much that the turtle can do about this without compromising the aerodynamic shape of the flipper. The problem is that as blood flows through the turtle’s flippers,it risks losing enough heat to lower the animal’s central body temperature when it returns. The solution is to allow the flippers to cool down without drawing heat away from the rest of the turtle’s body. The leatherback accomplishes this by arranging the blood vessels in the base of its flipper into a countercurrent exchange system. In a countercurrent exchange system, the blood vessels carrying cooled blood from the flippers run close enough to the blood vessels carrying warm blood from the body to pick up some heat from the warmer blood vessels; thus, the heat is transferred from the outgoing to the ingoing vessels before it reaches the flipper itself. This is the same arrangement found in an old-fashioned steam radiator, in which the coiled pipes pass heat back and forth as water courses through them. The leatherback is certainly not the only animal with such an arrangement; gulls have a countercurrent exchange in their legs. That is why a gull can stand on an ice floe without freezing. All this applies, of course, only to an adult leatherback. Hatchlings are simply too small to conserve body heat, even with insulation and countercurrent exchange systems. We do not know how old, or how large, a leatherback has to be before it can switch from a cold-blooded to a warm-blooded mode of life. Leatherbacks reach their immense size in a much shorter time than it takes other sea turtles to grow. Perhaps their rush to adulthood is driven by a simple need to keep warm. Paragraph 1: When it comes to physiology, the leatherback turtle is, in some ways, more like a reptilian whale than a turtle. It swims farther into the cold of the northern and southern oceans than any other sea turtle, and it deals with the chilly waters in a way unique among reptiles. ▉托福TPO15阅读Passage1题目： 1. The phrase “unique among” in the passage is closest in meaning to ○natural to ○different from all other ○quite common among ○familiar to 2. What can be inferred about whales from paragraph 1? ○They are considered by some to be reptiles. ○Their bodies are built in a way that helps them manage extremely cold temperatures.。

▉托福TPO3阅读Passage1原文文本： Architecture Architecture is the art and science of designing structures that organize and enclose space for practical and symbolic purposes. Because architecture grows out of human needs and aspirations, it clearly communicates cultural values. Of all the visual arts, architecture affects our lives most directly for it determines the character of the human environment in major ways. Architecture is a three-dimensional form. It utilizes space, mass, texture, line, light, and color. To be architecture, a building must achieve a working harmony with a variety of elements. Humans instinctively seek structures that will shelter and enhance their way of life. It is the work of architects to create buildings that are not simply constructions but also offer inspiration and delight. Buildings contribute to human life when they provide shelter, enrich space, complement their site, suit the climate, and are economically feasible. The client who pays for the building and defines its function is an important member of the architectural team. The mediocre design of many contemporary buildings can be traced to both clients and architects. In order for the structure to achieve the size and strength necessary to meet its purpose, architecture employs methods of support that, because they are based on physical laws, have changed little since people first discovered them—even while building materials have changed dramatically. The world’s architectural structures have also been devised in relation to the objective limitations of materials. Structures can be analyzed in terms of how they deal with downward forces created by gravity. They are designed to withstand the forces of compression (pushing together), tension (pulling apart), bending, or a combination of these in different parts of the structure. Even development in architecture has been the result of major technological changes. Materials and methods of construction are integral parts of the design of architecture structures. In earlier times it was necessary to design structural systems suitable for the materials that were available, such as wood, stone, brick. Today technology has progressed to the point where it is possible to invent new building materials to suit the type of structure desired. Enormous changes in materials and techniques of construction within the last few generations have made it possible to enclose space with much greater ease and speed and with a minimum of material. Progress in this area can be measured by the difference in weight between buildings built now and those of comparable size built one hundred years ago. Modern architectural forms generally have three separate components comparable to elements of the human body: a supporting skeleton or frame, an outer skin enclosing the interior spaces, and equipment, similar to the body’s vital organs and systems. The equipment includes plumbing, electrical wiring, hot water, and air-conditioning. Of course in early architecture—such as igloos and adobe structures—there was no such equipment, and the skeleton and skin were often one. Much of the world’s great architecture has been constructed of stone because of its beauty, permanence, and availability. In the past, whole cities grew from the arduous task of cutting and piling stone upon. Some of the world’s finest stone architecture can be seen in the ruins of the ancient Inca city of Machu Picchu high in the eastern Andes Mountains of Peru. The doorways and windows are made possible by placing over the open spaces thick stone beams that support the weight from above.A structural invention had to be made before the physical limitations of stone could be overcome and new architectural forms could be created. That invention was the arch, a curved structure originally made of separate stone or brick segments. The arch was used by the early cultures of the Mediterranean area chiefly for underground drains, but it was the Romans who first developed and used the arch extensively in aboveground structures. Roman builders perfected the semicircular arch made of separate blocks of stone. As a method of spanning space, the arch can support greater weight than a horizontal beam. It works in compression to divert the weight above it out to the sides, where the weight is borne by the vertical elements on either side of the arch. The arch is among the many important structural breakthroughs that have characterized architecture throughout the centuries. ▉托福TPO3阅读Passage1题目： Question 1 of 14 According to paragraph 1, all of the following statements about architecture are true EXCEPT: A. Architecture is visual art.. B. Architecture reflects the cultural values of its creators.. C. Architecture has both artistic and scientific dimensions.. D. Architecture has an indirect effect on life.. Question 2 of 14 The word “feasible ” in the passage is closest in meaning to。

TPO53托福阅读Passage1原文文本Questions About A Drama ClassListen to a conversation between a student and his drama professor.Professor: Hi Robert. So how's your paper going?Robert: Pretty well. It's a lot of work, but I’m getting into it, so I don't mind. I’ll probably have some questions for you in the next week or so.Professor: Okay. Glad to hear you’re progressing so well.Robert: Um… There was something you said at the end of the lecture on Tuesday, something about there not really being any original plays.Professor: There’s no such thing as an origi nal play. Yes. That's the direct quote from Charles Mee.Robert: Mee… that's with two “e”s, right?Professor: Yep. M-E-E. You'll probably be hearing a lot about him. He's becoming a pretty famous playwright.Robert: Yeah，well, I’ve been thinking about his quote. I mean there must be some original plays out there.Professor: I’ll grant that he's overstating things somewhat. But the theater does have a long tradition of borrowing. Take Shakespeare. Like most writers of his day, he borrowed plots from other sources unabashedly. And the ancient Greeks, all the plays they wrote were based on earlier plays, poems and myths.Robert: And borrowing applies to plays being written nowadays, too?Professor: T o some extent, yes. Mee, for example, he's made a career out o f remaking plays, one of which we’ll be studying soon. It’s called Full Circle and Mee based it on an earlier play by a German playwright.Robert: Oh Full Circle… Wasn't that based on the Caucasian Chalk Circle?Professor: That's right.Robert: I remember hearing about that play from my acting coach.Professor: Okay. Well, the Caucasian Chalk Circle was based on a play by yet another German playwright, someone who was fascinated by the ancient literatures of China, India and Persia, and many of his works were adapted from those literatures, including his version of the Chalk Circle which was based on an early Chinese play.Robert: So this Full Circle play, by Charles Mee, the one we're going to study, it's like the third or fourth remake. Wow… And we complain that Hollywood keeps making the same movies over and over again.Professor: Well, part of what Mee’s trying to do is drive home the point that: One, theater’s always a collaborative effort.Robert: Well, yeah, the playwright, the director, the actors, people have to work together to produce a play.Professor: Yes, of course. But Mee means historically. The dramatic literature of early periods is hugely influential in shaping later dramatic works.Robert: So it's like when the playwright bases a play on a previous playwright's theme or message.It's like they're talking toeach other, collaborating. Uh, just not at the same time right?Professor: Exactly. And the second point Mee's trying to make, I think, is that it's legitimate to retell an old story in a new way, in a way that’s, uh… more in line with contemporary concerns. So when playwrights reinvent or update an earlier play, it shouldn't be construed as a lack of imagination or an artistic failure.TPO53托福阅读Passage1题目Question 1 of 5Why does the man go to see the professor?A.

It served as the basis for a Hollywood film.B. It is indirectly based on a Chinese play.C. It has influenced a more recent play.D. It uses themes from ancient Greek literature.Question 4 of 5What two points does Charles Mee make about playwriting? Click on 2 answersA. Rewriting old plays to deal with modern issues is a respectable practice.B. Playwrights should preserve as much of the original as possible when updating an older play.C.

Memphis:United Egypt's First Capital[1]The city of Memphis,located on the Nile near the modern city of Cairo,was founded around 3100 B.C.as the first capital of a recently united Egypt.The choice of Memphis by Egypt's first kings reflects the site's strategic importance.■First,and most obvious,the apex of the Nile River delta was a politically opportune location for the state's administrative center,standing between the united lands of Upper and Lower Egypt and offering ready access to both parts of the country.The older predynastic(pre-3100BC)centers of power,This and Hierakonpolis,were too remote from the vast expanse of the delta,which had been incorporated into the united state.■Only a city within easy reach of both the Nile valley to the south and the more spread out,difficult terrain to the north could provide the necessary political control that the rulers of early dynastic Egypt(roughly 3000-2600 B.C.)required.■[2]The region of Memphis must have also served as an important node for transport and communications,even before the unification of Egypt.The region probably acted as a conduit for much,if not all,of the river-based trade between northern and southern Egypt.■Moreover,commodities(such as wine,precious oils,and metals)imported from the Near East by the royal courts of predynastic Upper Egypt would have been channeled through the Memphis region on their way south.In short,therefore,the site of Memphis offered the rulers of the Early Dynastic Period an ideal location for controlling internal trade within their realm,anessential requirement for a state-directed economy that depended on the movement of goods.[3]Equally important for the national administration was the ability to control communications within Egypt.The Nile provided the easiest and quickest artery of communication,and the national capital was,again,ideally located in this respect.Recent geological surveys of the Memphis region have revealed much about its topography in ancient times.It appears that the location of Memphis may have been even more advantageous for controlling trade,transport,and communications than was previously appreciated.Surveys and drill cores have shown that the level of the Nile floodplain has steadily risen over the last five millenniums.When the floodplain was much lower,as it would have been in predynastic and early dynastic times,the outwash fans(fan-shaped deposits of sediments)of various wadis(stream-beds or channels that carry water only during rainy periods)would have been much more prominent features on the east bank.The fan associated with the Wadi Hof extended a significant way into the Nile floodplain,forming a constriction in the vicinity of Memphis.The valley may have narrowed at this point to a mere three kilometers,making it the ideal place for controlling river traffic.[4]Furthermore,the Memphis region seems to have been favorably located for thecontrol not only of river-based trade but also of desert trade routes.The two outwash fans in the area gave access to the extensive wadi systems of the eastern desert.In predynastic times,the Wadi Digla may have served as a trade route between the Memphis region and the Near East,to judge from the unusual concentration of foreign artifacts found in the predynasticsettlement of Maadi.Access to,and control of,trade routes between Egypt and the Near East seems to have been a preoccupation of Egypt's rulers during the period of state formation.The desire to monopolize foreign trade may have been one of the primary factors behind the political unification of Egypt.The foundation of the national capital at the junction of an important trade route with the Nile valley is not likely to have been accidental.Moreover,the Wadis Hof and Digla provided the Memphis region with accessible desert pasturage.As was the case with the cities of Hierakonpolis and Elkab,the combination within the same area of both desert pasturage and alluvial arable land(land suitable for growing crops)was a particularly attractive one for early settlement;this combination no doubt contributed to the prosperity of the Memphis region from early predynastic times.1.The word"trivial"in the passage is closest in meaning toA.similarB.inaccurateC.smallD.significantParagraph 1 is marked with?答案：C选项正确解析：本题为词汇题，根据所给单词trivial定位到第一段More important than the amount of time Herodotus computed,which turns out to be trivial compared with the age of Earth,was the notion that one could estimate ages of geologic features by determining rates of the processes responsible for such features,and then assuming the rates to be roughly constant overtime.本句大致意思为：与地球的年龄相比，Herodotus这个人计算出来的时间量是trivial的，与其相比更重要的是一个概念，这个概念是一个人可以通过估计相应地理特征的某种过程的速度来估计地理特征的年龄……再以Herodotus为关键词定位这个time是什么，找到本段第三句，发现他是推测Nile Delta花了几千年形成的。

参考答案 while airplane and television are surely very important inventions, i believe computer is probably more helpful in peoples life. for one thing, computer helps people so much in their studies since it allows people to write research papers and create powerpoint presentations. you know, in the past, students had to rewrite their paper which costs them bunches of time. but now they only need to do some minor edit on the computer. for another, computer can be used as a convenient and efficient tool to communicate with others. people now have been accustomed to chat through online communication tools such as skype, qq and so forth. furthermore, computer can meet all our needs of entertainment, including music, movies and video games.up in big cities. others believe that it is better for children to grow up in small towns or rural areas. what is your opinion?参考答案personally speaking, children will definitely benefit more from living in big cities, especially metropolis. first of all, big cities provide children with high-quality education resources and facilities, which are not available in rural areas. you know, most of the prestigious schools are located in big cities which are of advanced facilities likeprojectors, computers and so on. on the other hand, children can receive better medical insurance since medical and healthcare technology is better in big cities. rural areas usually lack doctors with formal license, not even mention some checking machines. the myriad life of metropolis is indispensable to the all-round and harmonious development of childrens character.the woman expresses her opinion about the university?s plan. briefly summarize the plan. then state her opinion about the plan and explain the reasons she gives for holding that opinion.参考答案the student proposes that the university should build a parking lot, as it’s hard to find a parking place on campus and there’s a wood area suitable for the need. the speaker disagrees with the statement. there are two reasons. firstly, there are some places for parking near the dining hall and the library, several blocks away. and she doesnt think there should always be a parking spot outside the building they are visiting. moreover, the green area is the only place on campus where there is plenty of trees and students enjoy studying and reading there. school should leave the area alone instead of eliminating it for something they dont need.using the example from the lecture, explain the use of image advertising to sell products.参考答案in order to advertise a product, companies tend to link a positive image with their product and the image should be easy to remember. the professor talks about an example of a cookie company. the company uses a big bear as the image on the box of their cookies and the character is also shown on tv commercials. the image of big bear is easy to remember and when it dances and says something funny on tv, the children like it very much. therefore, year by year, the company sells more cookies than any of its competitors.briefly summarize the problem the speakers are discussing. then state which of the two solutions from the conversation you would recommend. explain the reasons for your recommendation.参考答案the speaker volunteers in an elementary school and she is supposed to take the kids for picnic in the weekends. but it’s going to rain the whole day that day. there are two solutionsfor her. firstly, she can reschedule the picnic next week andcall every family tonight, but someone may miss out. secondly, she can arrange the activity in a restaurant, but it’ll be less fun and cannot be called a picnic. compared with the solutions, i prefer the second, and at least children will not bedisappointed with the activity cancellation and they can rearrange the picnic next time.using the example of baboons from the lecture, explain two ways in which display behavior can help animals maintaingroup unity.参考答案group life provides animals with protection from predators and social companies. there are two kinds of display behaviors animal use to avoid conflicts and resolve conflicts within a group. the first is threatening. the behavior doesnt aim to harm, but send a signal of warning. take a kind of monkey for example. when two monkeys see food at the same time, one may threaten the other and after receiving the warning message, the other may leave without fighting. the second isto hug each other after punching. if two monkeys does fightwith each other over the food they found, they may hug afterthe physical attack, and the conflict is resolved.【篇二：托福阅读tpo1-35文本 mp3【整套】】xt>托福阅读tpo1-35文本+mp3【整套】摘要：备考托福使用tpo是考生在平时不过的事情了，备考托福阅读必备的资料就是托福阅读tpo，今天小编为大家带来托福阅读tpo1-35文本+mp3【整套】下载，小编是不是很贴心呢?不多说了，赶紧来看看学习吧。
