托福TPO16口语Task3阅读文本: Student Health Services Need Improvement The situation at the health center is unacceptable: you sit in a crowded waiting room for hours waiting to get treatment for minor ailments. Then when it’s your turn, you get about three minutes with an overworked doctor. I have two suggestions: first, the heath center needs to hire more doctors so that each patient receives quality treatment. And as far as the wait time issue is concerned, the health center is currently open Monday through Fridays, which means that people who get sick over the weekend wait until the following week to get treatment. So, opening the health center on weekends should solve that problem too. Sincerely, Megan Finch 托福TPO16口语Task3听力文本: Now listen to two students discussing the letter. Woman: Did you read that letter in the paper? Man: Sure, and though she's right about the problems, I don't think what she proposes will do much good. Woman: Really? Man: Yeah. Take her first suggestion: I mean, have you seen the health center Woman: Of course! Why? Man: Well…it's tiny, right?. It suffers from lack of space, so, unless they build more treatment rooms or offices or something… Woman: Oh, I see… Man: And also, her second suggestion. Woman: It seems like that'll help things out… Man: Well…not necessarily…I mean…think about it. A lot of students aren't even here on the weekends. Woman: That's true. Man: They leave town and get away; there's not a lot of people here. Woman: Yeah, like me, I got home probably…at least twice a month. Man: Right, and a lot of us leave campus for the weekend even more often than that. So there's just not a lot of demand for treatment then. See what I mean? 托福TPO16口语Task3题目: The man expresses his opinion about the student’s suggestions that are made in the letter. State the man’s opinion and explain the reasons he gives for holding that opinion. 托福TPO16口语Task3满分范文: Well, the man disagrees with the suggestions in the letter for two major reasons. First of all, he thinks that hiring more doctors won't solve the problem simply because the health center is tiny and therefore wouldn't support more doctors or patients. So he believes that there should be more room before hiring more doctors. Secondly, he says that opening the health center on weekends wouldn't fix the problem either, since students are generally away on weekends—there won't be many students there. Opening the health center on weekends makes no point at all. So the man disagrees with the suggestions in the letter. (104 words) 以上是给大家整理的托福TPO16口语Task3阅读文本+听力文本+题目+满分范文,希望对你有所帮助!。

【关键字】托福0308托福试题阅读(55minutes)Question 1-11If food is allowed to stand for some time, it putrefies .When the putrefied materialis examined microscopically ,it is found to be teeming with bacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 )generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did(10) this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether, the particles that it hadtrapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteurfound that in ordinary air these exists a variety of solid structures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodies resembledthe reproductive(15)structures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated that these bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary forspontaneous generation and that the air inside the sealed flask was affected in some way(25)by heating so that it would no longer support spontaneousgeneration. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck prevented microorganisms from getting in the flask.. Material sterilized in such a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’s influence on the develop ment of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’s argument against the theory of spontaneous generation . 2,The phrase “teeming with ”in line 2 is closest in meaning to(a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen on some food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word “resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the “guncotton” mentioned in paragraph 2 was to(a)trap particles for analysis(b)slow the process of putrefaction(c)increase the airflow to the microscopic slide(d)aid the mixing of alcohol and ether6,The author mention “1.0mm”in line 14 in describing the(a)thickness of a layer of organisms that was deposited on an object(b)diameter of the fibers that were in the guncotton filters(c)thickness of the microscope slides that were used(d)size of the particles that that were collected7.The word “postulated”in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experiment were remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefying materials(c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word “it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed that which of the following was important for the process to succeed ?(a)A sealed container(b)Fresh air(c)Heat(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to(a)store sterilized liquids for use in future experiments(b)prevent heat from building up in a solution(c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of airQuestions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society’s hero. In the minds of agrarian thinkers and writers ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,which ended in 1865 ,was the age of(5 )the farmer in the United States .Agrarian philosophers ,represented most eloquently byThomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a goodsociety, their political virtue ,and their Superior morality .And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10)all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15) launched exploring expeditions into prospective farmlands in the West .In addition ,government trade policies facilitated the exporting of agricultural products.For their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20)more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops andpure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunning rapidity .But farmers responded(25)less to the expectations of agrarians and governmentinducements than to growing market opportunities .European demand for food from the United States seemed insatiable . War, industrialization , and urbanization all kept demand high in Europe . United States citiesand industries grew as well; even industries not directly related to farming thrived becauseof the market, money ,and labor that agriculture provided .12.What does the passage mainly discuss?(a)The agrarian philosophy of Thomas Jefferson(b)The role of the national government in the development of agriculture(c)Improvements in farming techniques(d)The impact of the increased importance of the farmer13.The word “depended” in line 3 is closest in meaning to(a)improved(b)relied(c)demanded(d)explained14.The author mentions Thomas Jefferson in paragraph 1 as an example of(a)a leader during the Revolution(b)an inventor of new farming techniques(c)a philosopher who believed farmers were essential to the creation of a good society(d)a farmer who guided the agrarian movement toward an emphasis on economic development15.The phrase “subscribed to” in line 8 is closest in meaning to(a)contributed to(b)agreed with(c)thought about(d)expanded on16.Which of the following statements is supported by the information in paragraph 1?(a)All government policy makers accepted Jefferson’s views of agriculture and farmers.(b)Agricultural production declined between 1783 and 1861.(c)The majority of farmers worked for the government.(d)Agriculture was a vital part of the nation’s economy.17.According to the passage , the national and state governments did all of the following EXCEPT(a)build roads(b)import new plant varieties(c)give farmers money for their crops(d)develop policies that helped farmers export their products18.All of the following are mentioned as examples of farmers’ meeting the expectations of agrarian philosophers EXCEPT(a)obtaining information from farm newspapers(b)accumulating personal wealth(c)planting new crops(d)becoming more scientific19.The word “stunning” in line 24 is closest in meaning to(a)predictable(b)impressive(c)famous(d)gradual20.Which of the following statements is best supported by paragraph 4?(a)Agricultural development contributed to development in other parts of the economy.(b)European agricultural products were of a higher quality than those produced in the United States.(c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acid content) noralkaline(higher in salt content).fertilization is necessary to achieve the desired level of neutrality between thetwo. Arid America’s soils are typically a lkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many of these dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10)water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation methods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as one crosses the(25)border into the Northeast United States. As one proceedstoward the Southeast, broadleaf vegetation becomes dominant.Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A) The wide variety of climates(B) S oil types and vegetation patterns(C) I mproved irrigation methods and the expansion of agriculture(D) The change in precipitation patterns22 The word “spawn ” in line 1 is closest in meaning to(A) distinguish(B) e liminate(C) p rotect(D) create23 The word “partitioning” in line 2 is closest in meaning to(A) division(B) m odification(C) o pening(D) circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B) a n increase in farming(C) l arge amounts of rain(D) glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A) implied(B) i ncreased(C) i ndicated(D) informed26 How did glacial meltdown affect the soil in North America?(A) It redistributed the soil types(B) I t added salt to the soil(C) I t made the soil more neutral in content(D) It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refer s to the(A) movements of glacial deposits(B) p atterns of natural vegetation(C) h uman modification of the North American environment(D) distinction between humid America and arid America28 The word “transition” in line 23 is closest in meaning to(A) elevation(B) c hange(C) a dvantage(D) condition29 The passage supports which of the following statements?(A) Arid America is not necessarily characterized by the presenceof deserts(B) M ost of Canada and the northeastern United States consists ofshort-grass prairies wherever natural vegetation has not been modified by humans(C) T he accumulation of loess is primarily the result of irrigation(D) Glaciation removed the fertile layer of soil from much of theMississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used to capture high-speed movement on film as wellas to correct deficiencies of the normal surrounding lighting.Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash. A contemporary observer reported(10) that “this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’s. In the earliest type, the metal (15) was separated from the oxygen by a thin glass bulb. The flashwas fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignitedspontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygendifluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to a white-hot emissionof visible light. The smoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reflecting the light from their still-glowing neighbors. A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A) The history of the photoflash(B) T heories about how the eye reacts to light(C) T he technology of modern photography(D) The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A) recording of an image on film(B) g eneration of artificial light(C) c reation of a photographic emulsion(D) human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A) can produce repeated bursts of light(B) i ntensities colors in photographs(C) i s short enough not to bother human eyes(D) supplements existing lighting33 The word “ignited” in line 9 is closest in meaning to(A) set on fire(B) c ut into(C) o pened(D) shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed movement”(line 5)(D)”odd poses”(line 11)35 The word “evolution” in line 12 is closest in meaning to(A) publicity(B) a doption(C) d evelopment(D) manufacture36 The function of the glass in the first flashbulbs was to(A) produce the spark that initiated the flash(B) m agnify the light produced by the flash(C) p rotect the photographer from the heat of the flash(D) keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A) oxygen(B) b attery(C) w ire(D) current38 The word “momentarily” in line 20 is closest in meaning to(A) effortlessly(B) b riefly(C) e lectronically(D) gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A) rapid cooling(B) b right illumination(C) e lectrical conductivity(D) intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A) thicker wire(B) m ore oxygen(C) t hinner glass(D) continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portrayfragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15)Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewedthrough hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25)From then until 1886 Impressionism had all the zeal of a “church”, as the painter R enoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A) The impact of some artists’ resi stance to the fast pace of life(B) T he differences between two major styles of art(C) A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word “depict” in line 2 is closest in me aning to(A) reorganize(B) d eform(C) r epresent(D) justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A) The emphasis on people rather than nature scenes(B) T he way the subjects were presented from multiple angles(C) T he focus on small solid objects(D) The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A) They began by making sketches of their subjects(B) T hey painted their subjects out-of-doors(C) T hey preferred to paint from memory(D) They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A) achievement(B) a cceptance(C) a rrival(D) advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A) attracting attention from the public(B) a negative reaction from the press(C) a n immediate demand for the paintings exhibited(D) creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A) insult(B) e ncouragement(C) r eturn(D) credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A) The small number of paintings on display(B) L ack of interest in exhibitions by young artists(C) T he similarity between all the paintings exhibited(D) Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A) became as famous as Monet(B) w as consistently praised by art critics(C) d escribed the enthusiasm of the Impressionists for their work(D) was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A) art critics(B) f ellow artists(C) i ndividual differences(D) new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABACACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB此文档是由网络收集并进行重新排版整理.word可编辑版本!。
托福备考托福阅读34套TPO样题+解析+译文16--3 Planets in Our Solar System

托福考试 复习托福阅读TPO16(试题+答案+译文)第3篇:Planets in Our Solar System托福阅读原文The Sun is the hub of a huge rotating system consisting of nine planets, their satellites, and numerous small bodies, including asteroids, comets, and meteoroids. An estimated 99.85 percent of the mass of our solar system is contained within the Sun, while the planets collectively make up most of the remaining 0.15 percent. The planets, in order of their distance from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Under the control of the Sun's gravitational force, each planet maintains an elliptical orbit and all of them travel in the same direction.The planets in our solar system fall into two groups: the terrestrial (Earth-like) planets (Mercury, Venus, Earth, and Mars) and the Jovian (Jupiter-like) planets (Jupiter, Saturn, Uranus, and Neptune). Pluto is not included in either category, because its great distance from Earth and its small size make this planet's true nature a mystery.The most obvious difference between the terrestrial and the Jovian planets is their size. The largest terrestrial planet, Earth has a diameter only one quarter as great as the diameter of the smallest Jovian planet, Neptune, and its mass is only one seventeenth as great. Hence, the Jovian planets are often called giants. Also, because of their relative locations,the four Jovian planets are known as the outer planets, while the terrestrial planets are known as the inner planets. There appears to be a correlation between the positions of these planets and their sizes. Other dimensions along which the two groups differ markedly are density and composition. The densities of the terrestrial planets average about 5 times the density of water, whereas the Jovian planets have densities that average only 1.5 times the density of water. One of the outer planets, Saturn, has a density of only 0.7 that of water, which means that Saturn would float in water. Variations in the composition of the planets are largely responsible for the density differences. The substances that make up both groups of planets are divided into three groups—gases, rocks, and ices—based on their melting points. The terrestrial planets are mostly rocks: dense rocky and metallic material, with minor amounts of gases. The Jovian planets, on the other hand, contain a large percentage of the gases hydrogen and helium, with varying amounts of ices: mostly water, ammonia, and methane ices.The Jovian planets have very thick atmospheres consisting of varying amounts of hydrogen, helium, methane, and ammonia. By comparison, the terrestrial planets have meager atmospheres at best. A planet's ability to retain an atmosphere depends on its temperature and mass. Simply stated, a gas molecule can "evaporate" from a planet if it reaches a speed known as the escape velocity. For Earth, this velocity is 11 kilometers persecond. Any material, including a rocket, must reach this speed before it can leave Earth and go into space. The Jovian planets, because of their greater masses and thus higher surface gravities, have higher escape velocities (21-60 kilometers per second) than the terrestrial planets. Consequently, it is more difficult for gases to "evaporate" from them. Also, because the molecular motion of a gas depends on temperature, at the low temperatures of the Jovian planets even the lightest gases are unlikely to acquire the speed needed to escape. On the other hand, a comparatively warm body with a small surface gravity, like Earth's moon, is unable to hold even the heaviest gas and thus lacks an atmosphere. The slightly larger terrestrial planets Earth, Venus, and Mars retain some heavy gases like carbon dioxide, but even their atmospheres make up only an infinitesimally small portion of their total mass.The orderly nature of our solar system leads most astronomers to conclude that the planets formed at essentially the same time and from the same material as the Sun. It is hypothesized that the primordial cloud of dust and gas from which all the planets are thought to have condensed had a composition somewhat similar to that of Jupiter. However, unlike Jupiter, the terrestrial planets today are nearly void of light gases and ices. The explanation may be that the terrestrial planets were once much larger and richer in these materials but eventually lost them because of these bodies' relative closeness to the Sun, which meant that theirtemperatures were relatively high.托福阅读试题1.According to the passage, each of the following statements comparing terrestrial planets with Jovian planets is true EXCEPT:A.Terrestrial planets are closer to the Sun than Jovian planets.B.Terrestrial planets have smaller diameters than Jovian planets.C.Terrestrial planets have smaller masses than Jovian planets.D.Terrestrial planets travel in a different direction than Jovian planets do.2.The word markedly in the passage (paragraph 4) is closest in meaning toA.EssentiallyB.TypicallyC.ConsistentlyD.Noticeably3.Paragraph 4 mentions which of the following as a reason why terrestrial planets are dense?A.They are made up of three groups of substances.B.They are composed mainly of rocky and metallic materials.C.They contain more ice than Jovian planets.D.They contain relatively small amounts of water.4.Paragraph 4 supports each of the following statements about Saturn EXCEPT:A.It is less dense than any of the terrestrial planets.B.It contains no rocky material.C.It contains ices.D.It contains a large percentage of gases.5.The word meager in the passage (paragraph 5) is closest in meaning toA.richB.thinC.uniqueplex6.According to paragraph 5, which of the following statements is true of both Jovian and terrestrial planets?A.The thicker the atmosphere, the smaller the planet’s massB.The more varied the gases in the atmosphere, the higher the temperatureC.The higher the surface gravity, the higher the escape velocityD.The less the atmosphere contributes to the total mass, the lower the temperature7.According to paragraph 5, what is a major reason that Jovian planets have much thicker atmospheres than terrestrial planets do?A.Jovian planets have lower surface gravitiesB.Jovian planets have lower temperaturesC.Jovian planets have lower escape velocitiesD.Jovian planets’ gas molecules have higher average speeds8.Paragraph 5 supports which of the following statements about the ability of planets to retain gases?A.More-massive planets are less able to retain gases than less-massive ones.B.Planets are more likely to retain heavy gases than light gases.C.Jovian planets are unlikely to retain the lightest gases.D.Only terrestrial planets have been able to retain carbon dioxide.9.In calling the cloud of gas and dust from which the Sun and all the planets are thought to have condensed "primordial",(in paragraph 6) the author means that the cloud wasA.immense in sizeposed of similar particlesC.present at the very beginning of our solar system's formationD.created from a great variety of different materials10.The word eventually in the passage (paragraph 6) is closest in meaning toA.over timeB.long agoC.simplyD.certainly11.According to paragraph 6, what is a possible explanation for the lack of light gases and ices on terrestrial planets?A.The location of terrestrial planets caused them to lose some of the materials they once contained.B.Terrestrial planets were formed much later than Jovian planets.C.The composition of terrestrial planets was different from that of Jupiter.D.Terrestrial planets were formed out of different material than the Sun was.12. Look at the four squares [■] that indicate where the following sentence could be added to the passage. Where would the sentence best fit? This explains their relatively low densities.Paragraph 4: Other dimensions along which the two groups differ markedly are density and composition. The densities of the terrestrial planets average about 5 times the density of water, whereas the Jovian planets have densities that average only 1.5 times the density of water. One of the outer planets, Saturn, has a density of only 0.7 that of water, which means that Saturn would float in water.

0308托福试题阅读(55minutes)Question 1-11If food is allowed to stand for some time, it putrefies .When the putrefied materialis examined microscopically ,it is found to be teeming with bacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 ) generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did (10) this by passing air through guncotton filters, the fibers of which stop solid particles. After the guncotton was dissolved in a mixture of alcohol and ether, the particles that it hadtrapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteurfound that in ordinary air these exists a variety ofsolid structures ranging in size from0.01 mm to more than 1.0 mm .Many of thesebodies resembled the reproductive(15)structures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated that these bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary forspontaneous generation and that the air inside the sealed flask was affected in some way(25)by heating so that it would no longer supportspontaneous generation. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck prevented microorganisms from getting in the flask..Material sterilized in such a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’s influence on the development of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’s argument against the theory of spontaneous generation .2,The phrase “teeming with ”in line 2 is closest in meaning to(a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen on some food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word “resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the “guncotton” mentioned in paragraph 2 was to(a)trap particles for analysis(b)slow the process of putrefaction(c)increase the airflow to the microscopic slide(d)aid the mixing of alcohol and ether6,The author mention “1.0mm”in line 14 in describing the(a)thickness of a layer of organisms that was deposited on an object(b)diameter of the fibers that were in the guncotton filters(c)thickness of the microscope slides that were used(d)size of the particles that that were collected7.The word “postulated”in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experiment were remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefying materials(c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word “it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed that which of the following was important for the process to succeed ?(a)A sealed container(b)Fresh air(c)Heat(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to(a)store sterilized liquids for use in future experiments(b)prevent heat from building up in a solution(c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of air Questions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society’s hero. In the minds of agrarian thinkers and writers ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,which ended in 1865 ,was the age of(5 )the farmer in the United States .Agrarian philosophers ,represented most eloquently by Thomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a good society, their political virtue ,and their Superior morality .And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10) all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15) launched exploring expeditions into prospectivefarmlands in the West .In addition ,government trade policies facilitated the exporting of agricultural products.For their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20) more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops and pure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunning rapidity .But farmers responded (25) less to the expectations of agrarians andgovernment inducements than to growing market opportunities .European demand for food from the United States seemed insatiable . War, industrialization , and urbanization all kept demand high in Europe . United States citiesand industries grew as well; even industries not directly related to farming thrived becauseof the market, money ,and labor that agriculture provided .12.What does the passage mainly discuss?(a)The agrarian philosophy of Thomas Jefferson(b)The role of the national government in the development of agriculture(c)Improvements in farming techniques(d)The impact of the increased importance of the farmer13.The word “depended” in line 3 is closest in meaning to(a)improved(b)relied(c)demanded(d)explained14.The author mentions Thomas Jefferson in paragraph 1 as an example of(a)a leader during the Revolution(b)an inventor of new farming techniques(c)a philosopher who believed farmers were essential to the creation of a good society(d)a farmer who guided the agrarian movement toward an emphasis on economic development15.The phrase “subscribed to” in line 8 is closest in meaning to(a)contributed to(b)agreed with(c)thought about(d)expanded on16.Which of the following statements is supported by the information in paragraph 1?(a)All government policy makers accepted Jefferson’s views of agriculture and farmers.(b)Agricultural production declined between 1783 and 1861.(c)The majority of farmers worked for the government.(d)Agriculture was a vital part of the nation’s economy.17.According to the passage , the national and state governments did all of the following EXCEPT(a)build roads(b)import new plant varieties(c)give farmers money for their crops(d)develop policies that helped farmers export their products18.All of the following are mentioned as examples of farmers’ meeting the expectations of agrarian philosophers EXCEPT(a)obtaining information from farm newspapers(b)accumulating personal wealth(c)planting new crops(d)becoming more scientific19.The word “stunning” in line 24 is closest in meaning to(a)predictable(b)impressive(c)famous(d)gradual20.Which of the following statements is best supported by paragraph 4?(a)Agricultural development contributed to development in other parts of the economy.(b)European agricultural products were of a higher quality than those produced in the United States. (c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher inacid content) nor alkaline(higher in salt content).fertilization is necessary to achieve the desired level of neutrality between thetwo. Arid America’s soils are typically alkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many of these dryland soils, particularly in the Great Plains, are quite fertile, European settlers learned over a century ago that(10) water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation methods were perfected and finally provided a real opportunity to expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15) and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but the enormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20) the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as one crosses the (25) border into the Northeast United States. As oneproceeds toward the Southeast, broadleafvegetation becomes dominant. Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A)The wide variety of climates(B)Soil types and vegetation patterns(C)Improved irrigation methods and the expansion of agriculture(D)The change in precipitation patterns22 The word “spawn ” in line 1 is closest in meaning to(A)distinguish(B)eliminate(C)protect(D)create23 The word “partitioning” in line 2 is closest in meaning to(A)division(B)modification(C)opening(D)circulating24 According to the passage, acidic soils tent to be associated with(A)a high salt content(B)an increase in farming(C)large amounts of rain(D)glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A)implied(B)increased(C)indicated(D)informed26 How did glacial meltdown affect the soil in North America?(A)It redistributed the soil types(B)It added salt to the soil(C)It made the soil more neutral in content(D)It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refers to the(A)movements of glacial deposits(B)patterns of natural vegetation(C)human modification of the North American environment(D)distinction between humid America and arid America28 The word “transition” in line 23 is closest inmeaning to(A)elevation(B)change(C)advantage(D)condition29 The passage supports which of the following statements?(A)Arid America is not necessarily characterized by the presence of deserts(B)Most of Canada and the northeastern United States consists of short-grass prairies wherever natural vegetation has not been modified by humans(C)The accumulation of loess is primarily the result of irrigation(D)Glaciation removed the fertile layer of soil from much of the Mississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used tocapture high-speed movement on film as well as to correct deficiencies of the normal surrounding lighting. Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When the bag was ignited, the metal burned with an intense flash. A contemporary observer reported (10) that “this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’s. In the earliest type, the metal (15) was separated from the oxygen by a thin glass bulb. The flash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignitedspontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygen difluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to awhite-hot emission of visible light. The smoke particles are so small that they cool rapidly; butsince they are white, they contribute to thebrilliance by reflecting the light from their still-glowing neighbors. A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A)The history of the photoflash(B)Theories about how the eye reacts to light(C)The technology of modern photography(D)The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A)recording of an image on film(B)generation of artificial light(C)creation of a photographic emulsion(D)human eye to react to light32 According to the passage, an advantage of usinga photoflash is that it(A)can produce repeated bursts of light(B)intensities colors in photographs(C)is short enough not to bother human eyes(D)supplements existing lighting33 The word “ignited” in line 9 is closest inmeaning to(A)set on fire(B)cut into(C)opened(D)shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed movement”(line 5)(D)”odd poses”(line 11)35 The word “evolution” in line 12 is closest in meaning to(A)publicity(B)adoption(C)development(D)manufacture36 The function of the glass in the first flashbulbs was to(A)produce the spark that initiated the flash(B)magnify the light produced by the flash(C)protect the photographer from the heat of the flash(D)keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A)oxygen(B)battery(C)wire(D)current38 The word “momentarily” in line 20 is closest in meaning to(A)effortlessly(B)briefly(C)electronically(D)gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A)rapid cooling(B)bright illumination(C)electrical conductivity(D)intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A)thicker wire(B)more oxygen(C)thinner glass(D)continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected light in all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15) Impressionism acquired its name not fromsupporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewed through hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25) From then until 1886 Impressionism had all the zeal of a “church”, as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A)The impact of some artists’ resistance to the fast pace of life(B)The differences between two major styles of art(C) A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word “depict” in line 2 is closest in meaning to(A)reorganize(B)deform(C)represent(D)justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A)The emphasis on people rather than nature scenes(B)The way the subjects were presented from multiple angles(C)The focus on small solid objects(D)The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A)They began by making sketches of their subjects(B)They painted their subjects out-of-doors(C)They preferred to paint from memory(D)They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A)achievement(B)acceptance(C)arrival(D)advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A)attracting attention from the public(B) a negative reaction from the press(C)an immediate demand for the paintings exhibited(D)creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A)insult(B)encouragement(C)return(D)credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A)The small number of paintings on display(B)Lack of interest in exhibitions by young artists(C)The similarity between all the paintingsexhibited(D)Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A)became as famous as Monet(B)was consistently praised by art critics(C)described the enthusiasm of the Impressionists for their work(D)was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A)art critics(B)fellow artists(C)individual differences(D)new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABACACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

respect和review都不靠谱;revise单纯的改变也不是作者的意思3.以shop owners做关键词定位至第二句,但第二句没有回答问题,所以往后看,后一句说老板和工人之间的界限被blur模糊了,而且他们同吃同住一起工作,所以答案是D。
A的workersrank原文没说;B说对不同工人态度不同,与原文相反;C的unbreakable contract与最后一句相反4.修辞目的题,先看修辞点所在句子,只是一个例子,放弃;往前看,说有行业协会互助互惠,但这明显也还是一个例子,所以看本段中心句,说这种生产方式倾向于促进自律平等的同业协会的发展,所以答案是C5.EXCEPT题,排除法。
A的support workers和upholdprinciples做关键词定位至第二句,原文的mutual aid andprotection等于support workers,maintaneance ofprofessional standards等于uphold principles,A正确,不选;B的geographic area原文没有对应点,错,选;C的vote做关键词定位至最后一句,正确,不选;D的equals做关键词定位至最后一句,正确,不选6.consensus合约,同意,协定,所以D的agreement正确。

老托福阅读试题及答案:PASSAGE16老托福阅读试题及答案: 16The first flying vertebrates were true reptiles in which one of the fingers of the front limbs became very elongated, providing support for a flap of stretched skin that served as a wing. These were the pterosaurs, literally the "winged lizards." The earliest pterosaurs arose near the end of the Triassic period of the Mesozoic Era, some 70 million years before the first known fossils of true birds occur, and they presumably dominated the skies until they were eventually displaced by birds. Like the dinosaurs, some the pterosaurs became gigantic; the largest fossil discovered is of an individual that had a wingspan of 50 feet or more, larger than many airplanes. These flying reptiles had large, tooth-filled jaws, but their bodies were small and probably without the necessary powerful muscles for sustained wing movement. They must have been e某pert gliders, not skillful fliers, relying on wind power for their locomotion.Birds, despite sharing common reptilian ancestors with pterosaurs, evolved quite separately and have been much more successful in their dominance of the air. They are an e某ample of a common theme in evolution, the more or less parallel development of different types of body structure and function for the same reason —in this case, for flight. Although the fossil record, as always, is not complete enough to determine definitively the evolutionary lineage of the birds or in as much detail as one would like, it is better in this case than for many other animal groups. That is because of the unusual preservation in a limestone quarry in southern Germany of Archaeoptery某, a fossil that many have called the linkbetween dinosaurs and birds. Indeed, had it not been for the superb preservation of these fossils, they might well have been classified as dinosaurs. They have the skull and teeth of a reptile as well as a bony tail, but in the line-grained limestone in which these fossils occur there are delicate impressions of feathers and fine details of bone structure that make it clear that Archaeoptery某 was a bird.All birds living today, from the great condors of the Andes to the tiniest wrens, trace their origin back to the Mesozoic dinosaurs.1. What does the passage mainly discuss?(A) Characteristics of pterosaur wings(B) The discovery of fossil remains of Archaeoptery某(C) Reasons for the e某tinction of early flying vertebrates(D) The development of flight in reptiles and birds2. Which of the following is true of early reptile wings?(A) They evolved from strong limb muscles.(B) They consisted of an e某tension of skin.(C) They connected the front and back limbs.(D) They required fingers of equal length.3. The word "literally" in line 3 is closest in meaning to(A) creating(B) meaning(C) related to(D) simplified4. It can be inferred from the passage that birds were probably dominant in the skies(A) in the early Triassic period(B) before the appearance of pterosaurs(C) after the decline of pterosaurs(D) before dinosaurs could be found on land.5. The author mentions airplanes in line 8 in order to(A) illustrate the size of wingspans in some pterosaurs(B) compare the energy needs of dinosaurs with those of modern machines(C) demonstrate the differences between mechanized flight and animal flight(D) establish the practical applications of the study of fossils6. The word "They" in line 10 refers to(A) powerful muscles(B) bodies(C) jaws(D) flying reptiles7. According to the passage , pterosaurs were probably "not skillful fliers" (lines 10-11) because(A) of their limited wingspan(B) of their disproportionately large bodies(C) they lacked muscles needed for e某tended flight(D) climate conditions of the time provided insufficient wind power8. In paragraph 2, the author discusses the development of flight in birds as resulting from(A) a similarity in body structure to pterosaurs(B) an evolution from pterosaurs(C) the dominance of birds and pterosaurs over land animals(D) a separate but parallel development process to that of pterosaurs9. The word "classified" in line 21 is closest in meaning to(A) perfected(B) replaced(C) categorized(D) protected10. Which of the following helped researchers determine that Archaeoptery某 was not a dinosaur?(A) Its tail(B) Its teeth(C) The shape of its skull(D) Details of its bone structure11. What is the significance of the discovery that was made in southern Germany?(A) It is thought to demonstrate that birds evolved from dinosaurs.(B) It is proof that the climate and soils of Europe have changed over time.(C) It suggests that dinosaurs were dominant in areas rich in limestone.(D) It supports the theory that Archaeoptery某 was apowerful dinosaur.正确答案:DBBCA DCDCDA托福阅读的实用技巧整理首先,无论什么技巧都必须要有基本的单词量做基础。

托福TPO16综合写作阅读原文文本:The United Kingdom(sometimes referred to as Britain)has a long and rich history of human settlement.Traces of buildings,tools,and art can be found from periods going back many thousands of years:from the Stone Age,through the Bronze Age,the Iron Age,the time of the Roman colonization,the Middle Ages,up to the beginnings of the industrial age.Yet for most of the twentieth century,the science of archaeology,dedicated to uncovering and studying old cultural artifacts,was faced with serious problems and limitations in Britain.First,many valuable artifacts were lost to construction projects.The growth of Britain's population,especially from the1950s on,spurred a lot of new construction in British cities,towns,and villages.While digging foundations for new buildings,the builders often uncovered archaeologically valuable ually, however,they proceeded with the construction and did not preserve the artifacts. Many archaeologically precious artifacts were therefore destroyed.Second,many archaeologists felt that the financial support for archaeological research was inadequate.For most of the twentieth century,archaeology was funded mostly through government funds and grants,which allowed archaeologists to investigate a handful of the most important sites but which left hundreds of other interesting projects without support.Furthermore,changing government priorities brought about periodic reductions in funding.Third,it was difficult to have a career in archaeology.Archaeology jobs were to be found at universities or with a few government agencies,but there were never many positions available.Many people who wanted to become archaeologists ended up pursuing other careers and contributing to archaeological research only as unpaid amateurs.托福TPO16综合写作听力原文文本:In1990,new rules and guidelines were adopted in United Kingdom and that had changed the whole feel of Archaeology in that country.The new guidelines improved the situation in all3areas discussed in the passage.First,the new guidelines state that before any construction project can start,the construction site has to be examined by archaeologists to see whether the site is of archaeological interest or value.If the site is of archaeological interest,the next step is for the builders, archaeologists and local government officials to get together and make a plan for preserving the archaeological artifacts,either by building around them or by excavating a document in them properly before the construction is allowed to proceed. Second,an important part of new guidelines is the rule that any archaeological workdone on the construction site will be paid for by the construction company not by the government.The construction company has to pay for the initial examination of the site,and then for all the work carried out under the preservation plan.This is whole new source of financial support.The funding from the construction company has allowed researchers to study a far great range of archaeological sites than they could in st,the new guidelines provide a lot of paid work for archaeologists,work that didn’t exist before.Expert archaeologists are now hired all stage of the process to examine the site for archaeological value,then have to drop the preservation plan to do the researcher and professional scientific manner and finally to process the data and write reports and articles.The increased job career opportunities in Archaeology have increased the number professional archaeologists in Britain which is now the highest it’s ever been.托福TPO16综合写作满分范文:The professor explained three aspects of the new guidelines adopted in the United Kingdom,each of which has successfully addressed the problems mentioned in the reading passage concerning the preservation of artifacts,the funding of archaeological research,and career opportunities in archaeology.First,the professor pointed out that according to the new guidelines,any construction project must undergo an evaluation process in order for the archaeological value of the site to be ascertained.If a site is determined to contain precious objects,a panel of experts is convened to draw up a preservation plan.This measure has proven very effective in addressing the first problem mentioned in the reading–careless and irresponsible construction projects being pursued without any regard for archaeological preservation.Second,the lecturer explained that the new guidelines shifted the responsibility for funding archaeological work,from initial examination to future preservation,from the government to construction companies. As a result of this shift,the second problem highlighted in the reading concerning insufficient government funds for archaeological research has been significantly addressed.The professor’s last point concerned the final problem raised in the reading material–a decline in archaeology-related job opportunities.She argued that thanks to the new guidelines,many skillful,full-time archaeological experts and professionals are now needed to handle work at various stages of archaeological investigation,research,and preservation.以上是给大家整理的托福TPO16综合写作阅读原文+听力原文+满分范文,希望对你有所帮助!。

Aviculturists, people who raise birds for commercial sale, have not yet learned how to simulate the natural incubation of parrot eggs in the wild. They continue to look for better ways to increase egg production and to improve chick survival rates.When parrots incubate their eggs in the wild, the temperature and humidity of the nest are controlled naturally. Heat is transferred from the bird's skin to the top portion of the eggshell, leaving the sides and bottom of the egg at a cooler temperature. This temperature gradient may be vital to successful hatching. Nest construction can contribute to this temperature gradient. Nests of loosely arranged sticks, rocks, or dirt are cooler in temperature at the bottom where the egg contacts the nesting material. Such nests also act as humidity regulators by allowing rain to drain into the bottom sections of the nest so that the eggs are not in direct contact with the water. As the water that collects in the bottom of the nest evaporates, the water vapor rises and is heated by the incubating bird, which adds significant humidity to the incubation environment.In artificial incubation programs, aviculturists remove eggs from the nests of parrots and incubate them under laboratory conditions. Most commercial incubators heat the eggs fairly evenly from top to bottom, thus ignoring the bird's method ofnatural incubation, and perhaps reducing the viability and survivability of the hatching chicks. When incubators are not used, aviculturists sometimes suspend wooden boxes outdoors to use as nests in which to place eggs. In areas where weather can become cold after eggs are laid, it is very important to maintain a deep foundation of nesting material to act as insulator against the cold bottom of the box. If eggs rest against the wooden bottom in extremely cold weather conditions, they can become chilled to a point where the embryo can no longer survive. Similarly, these boxes should be protected from direct sunlight to avoid high temperatures that are also fatal to the growing embryo. Nesting material should be added in sufficient amounts to avoid both extreme temperature situations mentioned above and assure that the eggs have a soft, secure place to rest.1. What is the main idea of the passage(A) Nesting material varies according to the parrots' environment.(B) Humidity is an important factor in incubating parrots' eggs.(C) Aviculturists have constructed the ideal nest box for parrots.(D) Wild parrots' nests provide information useful for artificial incubation.2. The word "They" in line 2 refers to(A) aviculturists(B) birds(C) eggs(D) rates3. According to paragraph 2, when the temperature of the sides and bottom of the egg are cooler than the top, then(A) there may be a good chance for successful incubation(B) the embryo will not develop normally(C) the incubating parent moves the egg to a new position.(D) the incubation process is slowed down4. According to paragraph 2, sticks, rocks, or dirt are used to(A) soften the bottom of the nest for the newly hatched chick(B) hold the nest together(C) help lower the temperature at the bottom of the nest(D) make the nest bigger5. According to paragraph 2, the construction of the nest allows water to(A) provide a beneficial source of humidity in the nest(B) loosen the materials at the bottom of the nest(C) keep the nest in a clean condition(D) touch the bottom of the eggs6. All of the following are part of a parrot's incubation method EXCEPT(A) heating the water vapor as it rises from the bottom of the nest(B) arranging nesting material at the bottom of the nest(C) transferring heat from the parent to the top of the eggshell(D) maintaining a constant temperature on the eggshell7. The word "suspend" in line 18 is closest in meaning to(A) build(B) paint(C) hang(D) move8. The word "fatal" in line 24 is closest in meaning to(A) close(B) deadly(C) natural(D) hot9.

托福备考托福阅读34套TPO样题+解析+译文16--2 Development of the Periodic Table

托福考试 复习托福阅读TPO16(试题+答案+译文)第2篇:Development of the Periodic Table托福阅读原文The periodic table is a chart that reflects the periodic recurrence of chemical and physical properties of the elements when the elements are arranged in order of increasing atomic number (the number of protons in the nucleus). It is a monumental scientific achievement, and its development illustrates the essential interplay between observation, prediction, and testing required for scientific progress. In the 1800's scientists were searching for new elements. By the late 1860's more than 60 chemical elements had been identified, and much was known about their descriptive chemistry. Various proposals were put forth to arrange the elements into groups based on similarities in chemical and physical properties. The next step was to recognize a connection between group properties (physical or chemical similarities) and atomic mass (the measured mass of an individual atom of an element). When the elements known at the time were ordered by increasing atomic mass, it was found that successive elements belonged to different chemical groups and that the order of the groups in this sequence was fixed and repeated itself at regular intervals. Thus when the series of elements was written so as to begin a new horizontal row with each alkali metal, elements of the samegroups were automatically assembled in vertical columns in a periodic table of the elements. This table was the forerunner of the modern table. When the German chemist Lothar Meyer and (independently) the Russian Dmitry Mendeleyev first introduced the periodic table in 1869-70, one-third of the naturally occurring chemical elements had not yet been discovered. Yet both chemists were sufficiently farsighted to leave gaps where their analyses of periodic physical and chemical properties indicated that new elements should be located. Mendeleyev was bolder than Meyer and even assumed that if a measured atomic mass put an element in the wrong place in the table, the atomic mass was wrong. In some cases this was true. Indium, for example, had previously been assigned an atomic mass between those of arsenic and selenium. Because there is no space in the periodic table between these two elements, Mendeleyev suggested that the atomic mass of indium be changed to a completely different value, where it would fill an empty space between cadmium and tin. In fact, subsequent work has shown that in a periodic table, elements should not be ordered strictly by atomic mass. For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater. Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element. All the isotopes of a given element have the same number of protons, but differ in their number of neutrons, and hence in their atomic mass. The isotopesof a given element have the same chemical properties but slightly different physical properties. We now know that atomic number (the number of protons in the nucleus), not atomic mass number (the number of protons and neutrons), determines chemical behavior. Mendeleyev went further than Meyer in another respect: he predicted the properties of six elements yet to be discovered. For example, a gap just below aluminum suggested a new element would be found with properties analogous to those of aluminum. Mendeleyev designated this element "eka-aluminum" (eka is the Sanskrit word for "next") and predicted its properties. Just five years later an element with the proper atomic mass was isolated and named gallium by its discoverer. The close correspondence between the observed properties of gallium and Mendeleyev’s predictions for eka-aluminum lent strong support to the periodic law. Additional support came in 1885 when eka-silicon, which had also been described in advance by Mendeleyev, was discovered and named germanium.The structure of the periodic table appeared to limit the number of possible elements. It was therefore quite surprising when John William Strut (Lord Rayleigh, discovered a gaseous element in 1894 that did not fit into the previous classification scheme. A century earlier, Henry Cavendish had noted the existence of a residual gas when oxygen and nitrogen are removed from air, but its importance had not been realized.Together with William Ramsay, Rayleigh isolated the gas (separating it from other substances into its pure state) and named it argon. Ramsay then studied a gas that was present in natural gas deposits and discovered that it was helium, an element whose presence in the Sun had been noted earlier in the spectrum of sunlight but that had not previously been known on Earth. Rayleigh and Ramsay postulated the existence of a new group of elements, and in 1898 other members of the series (neon, krypton, and xenon) were isolated.托福阅读试题1.The phrase interplay in the passage (paragraph 1) is closest in meaning toA.sequenceB.interpretationC.requirementD.interaction2.According to paragraph 1, what pattern did scientists notice when the known elements were written in order of increasing atomic mass?A.The elements of the group of alkali metals were the first elements in the order of increasing atomic mass.B.Repetition of the same atomic masses for elements in different groupsappeared.C.Elements with similar chemical properties appeared in the listing at regular intervals.D.Elements were chemically most similar to those just before and after them in the order.3.In paragraph 2, what is the author's purpose in presenting the information about the decision by Meyer and Mendeleyev to leave gaps in the periodic table?A.To illustrate their confidence that the organizing principles of the periodic table would govern the occurrence of all chemical elementsB.To indicate that some of their analyses of periodic physical and chemical properties were later found to be wrongC.To support the idea that they were unwilling to place new elements in the periodic tableD.To indicate how they handled their disagreement about where to place new elements4.What reason does the author provide for the claim that Mendeleyev was bolder than Meyer?(in paragraph 2)A.Mendeleyev corrected incorrect information Meyer had proposed.B.Mendeleyev assumed that some information believed to be true about the elements was incorrect.C.Mendeleyev argued that Meyer had not left enough gaps in theperiodic table.D.Mendeleyev realized that elements were not ordered by atomic mass in the periodic table.5.According to paragraph 2, why did Mendeleyev suggest changing the atomic mass of indium?A.Because indium did not fit into the periodic table in the place predicted by its atomic mass.B.Because there was experimental evidence that the atomic mass that had been assigned to indium was incorrect.C.Because there was an empty space between cadmium and tin in the periodic table.D.Because the chemical properties of indium were similar to those of arsenic and selenium.6.It can be inferred from paragraph 2 that tellurium comes before iodine in the periodic table even though tellurium's atomic mass is slightly greater becauseA.iodine is less common than telluriumB.both iodine and tellurium have no isotopesC.the chemical behavior of tellurium is highly variableD.the atomic number of tellurium is smaller than that of iodine7.The phrase “abundance” in the passage (paragraph 2) is closest in meaning toA.weightB.requirementC.plentyD.sequence8.The phrase “analogous to” in the passage (paragraph 3) is closest in meaning toA.predicted byB.expected ofC.similar toD.superior to9.Paragraph 3 suggests that Mendeleyev predicted the properties of eka-aluminum on the basis ofA.the atomic mass of aluminumB.the position of the gap in the periodic table that eka-aluminum was predicted to fillC.the similarity of eka-aluminum to the other five missing elementsD.observation of the properties of gallium10.It can be inferred from paragraph 3 that the significance of the discovery of gallium was that it supported which of the following?A.The idea that aluminum was correctly placed in the periodic table.B.Mendeleyev's prediction that eka-silicon would be discovered next.C.The organizing principle of the periodic table.D.The idea that unknown elements existed.11.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage (paragraph 4)? Incorrect choices change the meaning in important ways or leave out essential information.A.Ramsay found evidence of helium in the spectrum of sunlight before he discovered that the element was also contained in natural gas deposits on Earth.B.Ramsay thought he had discovered a new element present in natural gas deposits, but he was wrong since that element had been previously observed elsewhere on Earth.C.After Ramsay had discovered a new element, called helium, in natural gas deposits on Earth, he also found evidence of its presence in the Sun.D.Ramsay later discovered that helium, an element that was already known to be present in the Sun, was also present in natural gas deposits on Earth.12.The wo rd “postulated” in the passage (paragraph 4) is closest in meaning toA.hypothesizedB.discoveredC.reportedD.generated13.

0308托福试题阅读(55minutes)Question 1-11If food is allowed to stand for some time, it putrefies .When the putrefied materialis examined microscopically ,it is found to be teeming with bacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 )generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did(10) this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether, the particles that it hadtrapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteurfound that in ordinary air these exists a variety of solid structures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodies resembledthe reproductive(15)structures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated thatthese bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary forspontaneous generation and that the air inside the sealed flask was affected in some way(25)by heating so that it would no longer support spontaneousgeneration. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck prevented microorganisms from getting in the flask.. Material sterilized in such a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’s influence on the development of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’s argument agai nst the theory of spontaneous generation . 2,The phrase “teeming with ”in line 2 is closest in meaning to(a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen on some food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word “resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the “guncotton” mentioned in paragraph 2 was to(a)trap particles for analysis(b)slow the process of putrefaction(c)increase the airflow to the microscopic slide(d)aid the mixing of alcohol and ether6,The author mention “1.0mm”in line 14 in describing the(a)thickness of a layer of organisms that was deposited on an object(b)diameter of the fibers that were in the guncotton filters(c)thickness of the microscope slides that were used(d)size of the particles that that were collected7.The word “postulated”in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experiment were remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefying materials(c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word “it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed that which of the following was important for the process to succeed ?(a)A sealed container(b)Fresh air(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to(a)store sterilized liquids for use in future experiments(b)prevent heat from building up in a solution(c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of airQuestions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society’s hero. In the minds of agrarian thinkers and writers ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,which ended in 1865 ,was the age of(5 )the farmer in the United States .Agrarian philosophers ,represented most eloquently byThomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a goodsociety, their political virtue ,and their Superior morality .And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10)all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15) launched exploring expeditions into prospective farmlands in the West .In addition ,government trade policies facilitated the exporting of agriculturalFor their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20)more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops andpure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunning rapidity .But farmers responded(25)less to the expectations of agrarians and governmentinducements than to growing market opportunities .European demand for food from the United States seemed insatiable . War, industrialization , and urbanization all kept demand high in Europe . United States citiesand industries grew as well; even industries not directly related to farming thrived becauseof the market, money ,and labor that agriculture provided .12.What does the passage mainly discuss?(a)The agrarian philosophy of Thomas Jefferson(b)The role of the national government in the development of agriculture(c)Improvements in farming techniques(d)The impact of the increased importance of the farmer13.The word “depended” in line 3 is closest in meaning to(a)improved(b)relied(c)demanded(d)explained14.The author mentions Thomas Jefferson in paragraph 1 as an(a)a leader during the Revolution(b)an inventor of new farming techniques(c)a philosopher who believed farmers were essential to the creation of a good society(d)a farmer who guided the agrarian movement toward an emphasis on economic development15.The phrase “subscribed to” in line 8 is closest in meaning to(a)contributed to(b)agreed with(c)thought about(d)expanded on16.Which of the following statements is supported by the information in paragraph 1?(a)All government policy makers accepted Jefferson’s views of agriculture and farmers.(b)Agricultural production declined between 1783 and 1861.(c)The majority of farmers worked for the government.(d)Agriculture was a vital part of the nation’s economy.17.According to the passage , the national and state governments did all of the following EXCEPT(a)build roads(b)import new plant varieties(c)give farmers money for their crops(d)develop policies that helped farmers export their products18.All of the following are mentioned as examples of farmers’ meeting the expectations of agrarian philosophers EXCEPT(a)obtaining information from farm newspapers(b)accumulating personal wealth(c)planting new crops(d)becoming more scientific19.The word “stunning” in line 24 is closest in meaning to(a)predictable(b)impressive(c)famous(d)gradual20.Which of the following statements is best supported by paragraph 4?(a)Agricultural development contributed to development in other parts of the economy.(b)European agricultural products were of a higher quality than those produced in the United States.(c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acid content) noralkaline(higher in salt content).fertilization is necessary to achieve the desired level of neutrality between thetwo. A rid America’s soils are typically alkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many of these dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10)water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation methods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as one crosses the(25)border into the Northeast United States. As one proceedstoward the Southeast, broadleaf vegetation becomes dominant.Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A) The wide variety of climates(B) S oil types and vegetation patterns(C) I mproved irrigation methods and the expansion of agriculture(D) The change in precipitation patterns22 The word “spawn ” in line 1 is closest in meaning to(A) distinguish(B) e liminate(C) p rotect(D) create23 The word “partitioning” in line 2 is closest in meaning to(A) division(B) m odification(C) o pening(D) circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B) a n increase in farming(C) l arge amounts of rain(D) glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A) implied(B) i ncreased(C) i ndicated(D) informed26 How did glacial meltdown affect the soil in North America?(A) It redistributed the soil types(B) I t added salt to the soil(C) I t made the soil more neutral in content(D) It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refers to the(A) movements of glacial deposits(B) p atterns of natural vegetation(C) h uman modification of the North American environment(D) distinction between humid America and arid America28 The word “transition” in line 23 is closest in meaning to(A) elevation(B) c hange(C) a dvantage(D) condition29 The passage supports which of the following statements?(A) Arid America is not necessarily characterized by the presenceof deserts(B) M ost of Canada and the northeastern United States consists ofshort-grass prairies wherever natural vegetation has not been modified by humans(C) T he accumulation of loess is primarily the result of irrigation(D) Glaciation removed the fertile layer of soil from much of theMississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used to capture high-speed movement on film as wellas to correct deficiencies of the normal surrounding lighting.Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash. A contemporary observer reported(10) that “this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd pose s.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’s. In the e arliest type, the metal (15) was separated from the oxygen by a thin glass bulb. The flash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignitedspontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygendifluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to a white-hot emissionof visible light. The smoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reflecting the light from their still-glowing neighbors. A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A) The history of the photoflash(B) T heories about how the eye reacts to light(C) T he technology of modern photography(D) The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A) recording of an image on film(B) g eneration of artificial light(C) c reation of a photographic emulsion(D) human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A) can produce repeated bursts of light(B) i ntensities colors in photographs(C) i s short enough not to bother human eyes(D) supplements existing lighting33 The word “ignited” in line 9 is closest in mea ning to(A) set on fire(B) c ut into(C) o pened(D) shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed movement”(line 5)(D)”odd poses”(line 11)35 The wo rd “evolution” in line 12 is closest in meaning to(A) publicity(B) a doption(C) d evelopment(D) manufacture36 The function of the glass in the first flashbulbs was to(A) produce the spark that initiated the flash(B) m agnify the light produced by the flash(C) p rotect the photographer from the heat of the flash(D) keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A) oxygen(B) b attery(C) w ire(D) current38 The word “momentarily” in line 20 is closest in mean ing to(A) effortlessly(B) b riefly(C) e lectronically(D) gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A) rapid cooling(B) b right illumination(C) e lectrical conductivity(D) intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A) thicker wire(B) m ore oxygen(C) t hinner glass(D) continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15)Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewedthrough hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25)From then until 1886 Impressionism had all the zeal of a “church”, as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A) The impact of some artists’ resistance to the fast pace of life(B) T he differences between two major styles of art(C) A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word “depict” in line 2 is closest in meaning to(A) reorganize(B) d eform(C) r epresent(D) justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A) The emphasis on people rather than nature scenes(B) T he way the subjects were presented from multiple angles(C) T he focus on small solid objects(D) The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A) They began by making sketches of their subjects(B) T hey painted their subjects out-of-doors(C) T hey preferred to paint from memory(D) They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A) achievement(B) a cceptance(C) a rrival(D) advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A) attracting attention from the public(B) a negative reaction from the press(C) a n immediate demand for the paintings exhibited(D) creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A) insult(B) e ncouragement(C) r eturn(D) credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A) The small number of paintings on display(B) L ack of interest in exhibitions by young artists(C) T he similarity between all the paintings exhibited(D) Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A) became as famous as Monet(B) w as consistently praised by art critics(C) d escribed the enthusiasm of the Impressionists for their work(D) was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A) art critics(B) f ellow artists(C) i ndividual differences(D) new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABACACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

托福TPO16口语Task4阅读文本:Social LoafingWhen people work in groups to perform a task, individual group members may feel less motivated to contribute when one person is held directly responsible for completing the task. The result is that people may not work as hard, or accomplish as much as they would if they were working alone and their individual output were being measured. This decrease in personal effort, especially on a simple group task is known as social loafing. While it is not a deliberate behavior, the consequence of social loafing is less personal efficiency when working in groups than when working on one’s own.托福TPO16口语Task4听力文本:Listen to part of a lecture in a psychology class.(man) Now a study was done that illustrated this phenomenon. In the study people were given an ordinary task that everyone has probably done before. They were simply asked to peel potatoes, and to peel as many potatoes as possible in a given amount of time. Ok so, some people worked alone, and they were told that the number of potatoes they each peeled would be recorded. Others peeled potatoes together, as part of a group, and they were told that only the total number of potatoes peeled would be recorded. So it would be impossible to tell how many any one person had done.Then researchers compared the results of people who worked alone and those who worked together to see if there was any difference. That is, theytook the average score of the people working alone and compared it to the average score of the people working together in a group, and they did discover a difference! It turns out that people working in a group peeled significantly fewer potatoes that people who worked alone.托福TPO16口语Task4题目:Using the example from the lecture, explain what social loafing is, and how it affects behavior.托福TPO16口语Task4满分范文:The phenomenon that an individual tends to decrease his/her effort in a task conducted by a group is called social loafing. According to the professor, a study was done to illustrate the phenomenon. In the study, some people were asked to peel as many potatoes as possible within a given amount of time. Some of them worked alone,and they were told that the number of potatoes that each of them had peeled would be recorded. Others worked in a group and were told that only the total number of potatoes would be recorded, and there was no counting of how many each individual had peeled. When the results were compared, the researcher discovered that the individuals in a group peeled much less potatoes than those working alone. So this study suggests that when in a group, people are likely to contribute less since they don't think they're directly responsible for the task.

However, the speaker challenges these points by arguing that solar energy is not as renewable as it seems due to the limited lifespan of solar panels. They also mention that the production of solar panels has a significant environmental impact, including the use of harmful chemicals and the generation of waste. Furthermore, the speaker contends that solar energy's reliance on sunlight makes it an unreliable source of energy, as it is not available during cloudy days or at night, which contradicts the reading's claim of energy independence.Independent Writing Task: Do you agree or disagree with the following statement? Technology has made our lives much easier than our grandparents had it.Sample Response:I agree that technology has made our lives significantly easier than our grandparents' lives. For instance, advancements in communication technology have allowed us to stay connected with friends and family across the globe with ease, something our grandparents could only dream of. Additionally, technology has revolutionized the way we work, with tools like computers and the internet streamlining tasks and increasing productivity. In terms of healthcare, modern technology hasled to breakthroughs in medical treatments and diagnostic tools, improving the quality and longevity of life. While it is true that technology has its drawbacks, such as over-reliance and privacy concerns, the overall impact on our lives has been overwhelmingly positive, making our daily routines and tasks more manageable and efficient compared to our grandparents' experiences.。

It is a monumental scientific achievement, and its development illustrates the essential interplay between observation, prediction, and testing required for scientific progress. In the 1800's scientists were searching for new elements. By the late 1860's more than 60 chemical elements had been identified, and much was known about their descriptive chemistry. Various proposals were put forth to arrange the elements into groups based on similarities in chemical and physical properties. The next step was to recognize a connection between group properties (physical or chemical similarities) and atomic mass (the measured mass of an individual atom of an element). When the elements known at the time were ordered by increasing atomic mass, it was found that successive elements belonged to different chemical groups and that the order of the groups in this sequence was fixed and repeated itself at regular intervals. Thus when the series of elements was written so as to begin a new horizontal row with each alkali metal, elements of the same groups were automatically assembled in vertical columns in a periodic table of the elements. This table was the forerunner of the modern table.¡¡¡¡When the German chemist Lothar Meyer and (independently) the Russian Dmitry Mendeleyev first introduced the periodic table in 1869-70, one-third of the naturally occurring chemical elements had not yet been discovered. Yet both chemists were sufficiently farsighted to leave gaps where their analyses of periodic physical and chemical properties indicated that new elements should be located. Mendeleyev was bolder than Meyer and even assumed that if a measured atomic mass put an element in the wrong place in the table, the atomic mass was wrong. In some cases this was true. Indium, for example, had previously been assigned an atomic mass between those of arsenic and selenium. Because there is no space in the periodic table between these two elements, Mendeleyev suggested that the atomic mass of indium be changed to a completely different value, where it would fill an empty space between cadmium and tin. In fact, subsequent work has shown that in a periodic table, elements should not be ordered strictly by atomic mass. For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater. Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element.All the isotopes of a given element have the same number of protons, but differ in their number of neutrons, and hence in their atomic mass. The isotopes of a given element have the same chemical properties but slightly different physical properties. We now know that atomic number (the number of protons in the nucleus), not atomic mass number (the number of protons and neutrons), determines chemical behavior.¡¡¡¡Mendeleyev went further than Meyer in another respect: he predicted the properties of six elements yet to be discovered. For example, a gap just below aluminum suggested a new element would be found with properties analogous to those of aluminum. Mendeleyev designated this element "eka-aluminum" (eka is the Sanskrit word for "next") and predicted its properties. Just five years later an element with the proper atomic mass was isolated and named gallium by its discoverer. The close correspondence between the observed properties of gallium and Mendeleyev¡¯s predictions for eka-aluminum lent strong support to the periodic law. Additional support came in 1885 when eka-silicon, which had also been described in advance by Mendeleyev, was discovered and named germanium.¡¡¡¡The structure of the periodic table appeared to limit the number of possible elements. It was therefore quite surprising when John William Strut (Lord Rayleigh, discovered a gaseous element in 1894 that did not fit into the previous classification scheme. A century earlier, Henry Cavendish had noted the existence of a residual gas when oxygen and nitrogen are removed from air, but its importance had not been realized. Together with William Ramsay, Rayleigh isolated the gas (separating it from other substances into its pure state) and named it argon. Ramsay then studied a gas that was present in natural gas deposits and discovered that it was helium, an element whose presence in the Sun had been noted earlier in the spectrum of sunlight but that had not previously been known on Earth. Rayleigh and Ramsay postulated the existence of a new group of elements, and in 1898 other members of the series (neon, krypton, and xenon) were isolated.¡¡¡¡Paragraph 1: The periodic table is a chart that reflects the periodic recurrence of chemical and physical properties of the elements when the elements are arranged in order of increasing atomic number (the number of protons in the nucleus). It is a monumental scientific achievement, and its development illustrates the essential interplay between observation, prediction, and testing required for scientific progress. In the 1800's scientists were searching for new elements. By the late 1860's more than 60 chemical elements had been identified, and much was known about their descriptive chemistry. Various proposals were put forth to arrange the elements into groups based on similarities in chemical and physical properties. The next step was to recognize a connection between group properties (physical or chemical similarities) and atomic mass (the measured mass of an individual atom of an element). When the elements known at the time were ordered by increasing atomic mass, it was found that successive elements belonged to different chemical groups and that the order of the groups in this sequence was fixed and repeated itself at regular intervals. Thus when。

老托福阅读真题及答案:PASSAGE 16The first flying vertebrates were true reptiles in which one of the fingers of the front limbs became very elongated, providing support for a flap of stretched skin that served as a wing. These were the pterosaurs, literally the "winged lizards." The earliest pterosaurs arose near the end of the Triassic period of the Mesozoic Era, some 70 million years before the first known fossils of true birds occur, and they presumably dominated the skies until they were eventually displaced by birds. Like the dinosaurs, some the pterosaurs became gigantic; the largest fossil discovered is of an individual that had a wingspan of 50 feet or more, larger than many airplanes. These flying reptiles had large, tooth-filled jaws, but their bodies were small and probably without the necessary powerful muscles for sustained wing movement. They must have been expert gliders, not skillful fliers, relying on wind power for their locomotion.Birds, despite sharing common reptilian ancestors with pterosaurs, evolved quite separately and have been much more successful in their dominance of the air. They are an example of a common theme in evolution, the more or less parallel development of different types of body structure and function for the same reason — in this case, for flight. Although the fossil record, as always, is not complete enough to determine definitively the evolutionary lineage of the birds or in as much detail as one would like, it is better in this case than for many other animal groups. That is because of the unusual preservation in a limestone quarry in southern Germany of Archaeopteryx, a fossil that many have called the link between dinosaurs and birds. Indeed, had it not been for the superb preservation of these fossils, they might well have been classified as dinosaurs. They have the skull and teeth of a reptile as well as a bony tail, but in the line-grained limestone in which these fossils occur there are delicate impressions of feathers and fine details of bone structure that make it clear that Archaeopteryx was a bird. All birds living today, from the great condors of the Andes to the tiniest wrens, trace their origin back to the Mesozoic dinosaurs.1. What does the passage mainly discuss?(A) Characteristics of pterosaur wings(B) The discovery of fossil remains of Archaeopteryx(C) Reasons for the extinction of early flying vertebrates(D) The development of flight in reptiles and birds2. Which of the following is true of early reptile wings?(A) They evolved from strong limb muscles.(B) They consisted of an extension of skin.(C) They connected the front and back limbs.(D) They required fingers of equal length.3. The word "literally" in line 3 is closest in meaning to(A) creating(B) meaning(C) related to(D) simplified4. It can be inferred from the passage that birds were probably dominant in the skies(A) in the early Triassic period(B) before the appearance of pterosaurs(C) after the decline of pterosaurs(D) before dinosaurs could be found on land.5. The author mentions airplanes in line 8 in order to(A) illustrate the size of wingspans in some pterosaurs(B) compare the energy needs of dinosaurs with those of modern machines(C) demonstrate the differences between mechanized flight and animal flight(D) establish the practical applications of the study of fossils6. The word "They" in line 10 refers to(A) powerful muscles(B) bodies(C) jaws(D) flying reptiles7. According to the passage , pterosaurs were probably "not skillful fliers" (lines 10-11) because(A) of their limited wingspan(B) of their disproportionately large bodies(C) they lacked muscles needed for extended flight(D) climate conditions of the time provided insufficient wind power8. In paragraph 2, the author discusses the development of flight in birds as resulting from(A) a similarity in body structure to pterosaurs(B) an evolution from pterosaurs(C) the dominance of birds and pterosaurs over land animals(D) a separate but parallel development process to that of pterosaurs9. The word "classified" in line 21 is closest in meaning to(A) perfected(B) replaced(C) categorized(D) protected10. Which of the following helped researchers determine that Archaeopteryx was not a dinosaur?(A) Its tail(B) Its teeth(C) The shape of its skull(D) Details of its bone structure11.
