托福TPO17听力Conversation2文本 Narrator: Listen to a conversation between a student and a food service manager. Student: Excuse me, Mrs. Hanson. My name is John, John Grant. I work as a waiter in the campus dining hall, in the faculty dining room. Manager: What can I do for you, John? Student: Well, I work week nights, except for Friday. I was wondering if I could switch from working the dinner service to working at lunch. Manager: That’s going to be a problem. I am afraid we don’t have any openings at lunch time. A lot of students want to work then, so it is really rare for us to have an open spot at that time of day. Student: Oh, you see, I have joined this group, the University Jazz Band, and the band’s practice time is right around dinner time. You know, it is so hard to get into this group, I must have auditioned like ten times since I have been at the school, so I am ... Anyway, so I was really hoping to have the dinner hour free so I can go to practice. Manager: Well, we do have other open times, like breakfast. Student: Eh, that won’t work, I am sorry. I mean that, I can’t work that early.I have this very important music class I got to take, and it is like, first thing in the morning. Manager: Well, if you don’t mind working in the kitchen, we’ve got some pretty flexible hours for students doing food-prep work, anything from early morning to late afternoon. Student: What’s prep work? Manager: You prepare food for the cooks. You know, like cutting up vegetables for soup, or cleaning greens for salads. Student: Oh, that doesn’t sound, I mean... Being a waiter, I get to see a lot of the professors, like in a different light, we joke around a little you know. In the classroom, they always have to be pretty formal, but ... Manager: Well, the money is no different since we pay students the same amount for any of the jobs here in food service, so it’s up to you. Student: Oh, man. I always thought that sacrificing for my art, that’d mean working long hours as a musician for, like, no money. I didn’t think it’d mean, peeling carrots. Manager: Let me see, I am offering you something that has the hours you want, it is right here on campus, and you make as much money as you did being a waiter, quite a sacrifice. Student: I am sorry, I know you are just trying to help. I guess I should look into the food-prep job. Manager: Ok, then, I’ll tell the kitchen manager that you will stop by tomorrow to talk about the job and schedule your hours. And I will let the dining hall manager know that he needs to find a new waiter for the evening. Student: Oh, ok, I guess that’s it. Thanks, Mrs. Hanson. 托福TPO17听力Conversation2题目 1.Why does the man go to see the woman? A. To complain about rude customers. B. To request an increase in his pay. C.

2017年托福听力考前训练试题及答案3
2017年托福听力考前训练试题及答案3Researchers in the field of psychology have found that one of the best ways to make an important decision, such as choosing a university to attend or a business to invest in, involves the utilization of a decision worksheet. Psychologists who study optimization compare the actual decisions made by people to theoretical ideal decisions to see how similar they are. Proponents of the worksheet procedure believe that it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets can take, they are all similar in their essential aspects. Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem. Next, the pertinent considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned anumerical value to reflect its relative importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points emerges as the best decision.Since most important problems are multifaceted, there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question "What will I do after graduation?" A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year.A decision-making worksheet begins with a succinct statement of the problem that will also help to narrow it. It is important to be clear about the distinction between long-range and immediate goals because long-range goals often involve a different decision than short-range ones.Focusing on long-range goals, a graduating student might revise the question above to "What will I do after graduation that will lead to successful career?"1. What does the passage mainly discuss?(A) A tool to assist in making complex decisions.(B) A comparison of actual decisions and ideal decisions(C) Research on how people make decisions(D) Differences between long-range and short-range decision making2. The word "essential" in line 7 is closest in meaning to(A) introductory(B) changeable(C) beneficial(D) fundamental3. The word "pertinent有关的，相关的" in line 9 is closest in meaning to(A) relevant(B) preceding 在先的，前面的，在前的(C) insightful 富有洞察力的(D) responsive4. Of the following steps, which occurs before the others in making a decision worksheet?(A) Listing the consequences of each solution(B) Calculating a numerical summary of each solution(C) Deciding which consequences are most important(D) Writing down all possible solutions5. According to decision-worksheet theory, an optimal decision is defined as one that(A) has the fewest variables to consider(B) uses the most decision worksheets(C) has the most points assigned to it(D) is agreed to by the greatest number of people6. The author develops the discussion in paragraph 1 by means of(A) describing a process(B) classifying types of worksheets(C) providing historical background(D) explaining a theory7. The author states that "On the average, people can keep about seven ideas in their minds at once (lines 17-18) to explain that(A) most decisions involve seven steps(B) human mental capacity has limitations(C) some people have difficulty making minor as well asmajor decisions(D) people can learn to keep more than seven ideas in their minds with practice8.

2017年托福复习资料模拟试题及答案(五)
2017年托福复习资料模拟试题及答案（五）•The Native American peoples of the north Pacific Coast created a highly complex maritime culture as they invented modes of production unique to their special environment. In addition to theirsophisticated technical culture, they also attained one of the most complex social organizations of any nonagricultural people in the world. In a division of labor similar to that of the hunting peoples in the interior and among foraging peoples throughout the world, the men did most of the fishing, and the women processed the catch. Women also specialized in the gathering of the abundantshellfish that lived closer to shore. They collected oysters, crabs, sea urchins, mussels, abalone, and clams, which they could gather while remaining close to their children. The maritime life harvested by the women not only provided food, but also supplied more of theraw materials for making tools than did fish gathered by the men. Of particular importance for the native tool kit before the introduction of metal was the wide knife made from the larger mussel shells, and a variety of cutting edges that could be made from other marine shells. The women used their tools to process all of the fish and marine mammals brought in by the men. They cleaned the fish, and dried vast quantities of them for the winter. They sun-dried fish when practical, but in the rainy climate of the coastal area they also used smokehouses to preserve tons of fish and other seafood annually. Each product had its own peculiar characteristics that demanded aparticular way of cutting or drying the meat, and each task required its own cutting blades and other utensils. After drying the fish, the women pounded some of them into fish meal, which was an easily transported food used in soups, stews, or other dishes to provide protein and thickening in the absence of fresh fish or while on long trips. The woman also made a cheese-like substance from a mixture of fish and roe by aging it in storehouses or by burying it in wooden boxes or pits lined with rocks and tree leaves. 1. Which aspectof the lives of the Native Americans of the north Pacific Coast does the passage mainly discuss? (A) Methods of food preservation (B) How diet was restricted by the environment (C) The contributions of women to the food supply (D) Difficulties inestablishing successful farms 2. The word "unique" in line 2 is closest in meaning to (A) comprehensible (B) productive(C) intentional (D) particular 3. The word "attained" in line3 is closest in meaning to (A) achieved (B) modified (C) demanded (D) spread 4. It can be inferred from paragraph 1 that the social organization of many agricultural peoples is (A) more complex than that of hunters and foragers (B) less efficient than that of hunters and foragers (C) more widespread than that of hunters and foragers (D) better documented than that of hunters and foragers 5. According to the passage , what is true of the "division of labor" mentioned in line 5? (A) It was first developed by Native Americans of the north Pacific Coast. (B) It rarely existed among hunting (C) It was a structure that the Native Americans of the north Pacific Coast shared with many other peoples. (D) It provided a form of social organization that was found mainly among coastal peoples. 6. The word "abundant" inline 7 is closest in meaning to (A) prosperous (B) plentiful (C) acceptable (D) fundamental 7. All of the following are true of the north Pacific coast women EXCEPT that they (A) were more likely to catch shellfish than other kinds of fish (B) contributed more materials for tool making than the men did (C) sometimes searched for food far inland from the coast (D) prepared and preserved the fish 8.

2017托福复习资料模拟试题及答案虽然不像每年只有一次，但是当然还是尽快过了好。
下面是整理的2017托福复习资料模拟试题及答案，希望对大家有用，更多信息请浏览!The observation of the skies has played a special part in the lives and cultures of peoples since the earliest of times. Evidence obtained from a site known as the Hole in the Rock, in Papago Park in Phoenix, Arizona, indicates that it might have been used as an observatory by a prehistoric people known as the Hohokam.The physical attributes of the site allow its use as a natural calendar/clock. The "hole" at Hole in the Rock is formed by two large overhanging rocks coming together at a point, creating a shelter with an opening large enough for several persons to pass through. The northeast-facing overhang has a smaller opening in its roof. It is this smaller hole that produces the attributes that may have been used as a calendar/clock.Because of its location in the shelter's roof, a beam of sunlight can pass through this second hole and cast a spot onto the shelter's wall and floor. This spot of light travels from west to east as the sun moves across the sky. It also moves from north to south and back again as the Earth travels around the Sun, the west-to-east movement could have been used to establish a daily clock, much like a sundial, while the north-to-south movement could have been used to establish a seasonal calendar.The spot first appears and starts down the surface of the wall of the shelter at different times of the morning depending on the time of the year. The spot grows in size from its first appearance until its maximum size is achieved roughly at midday. It then continues its downward movement until it reaches a point where it jumps to the floor of the shelter. As the Sun continues to move to the west, the spot continues to move across the shelter floor and down the butte, or hill, toward a group of small boulders. If a person is seated on a certain one of these rocks as the spot reaches it, the Sun can be viewed through the calendar hole. This occurs at different times in the afternoon depending on the time of year.1. What does the passage mainly discuss?(A) observations of the stars by ancient people(B) rock formations of Arizona(C) a site used by ancient people to measure time(D) the movement of the earth around the Sun2. The word "obtained" in line 2 is closest in meaning to(A) acquired(B) transported(C) covered(D) removed3. The word "attributes属性，特征" in line 5 is closest in meaning to(A) changes(B) characteristics(C) locations(D) dimensions4. The word "its" in line 10 refers to(A) roof(B) beam(C) hole(D) spot5. The word "establish" in line 15 is closest in meaning to(A) create(B) locate(C) consult(D) choose6. Which of the following is NOT true of the spot of light?(A) It is caused by sunlight passing through a hole.(B) It travels across the roof of the shelter.(C) Its movement is affected by the position of the Sun.(D) It movement could have been used to estimate the time of day.7. From which of the following can be the time of year be determined?(A) The movement of the spot of light from west to east(B) The speed with which the spot of light moves(C) The movement of the spot of light from north to south(D) The size of the sport of light at midday8. The word "roughly粗糙地" in line 18 is closest in meaning to(A) finally(B) harshly(C) uneasily(D) approximately9. The passage mentions that the Hole in the Rock was used as all of the following EXCEPT(A) a calendar(B) a home(C) a clock(D) an observatory10. Which of the following can be inferred from the fourth paragraph?(A) The boulders are located below the rock shelter.(B) The person seated on the rock cannot see the shelter.(C) After it passes the boulders, the spot of light disappears.(D) The spot of light is largest when it first appears.答案：CABCA BCDBA。

Passage OneThe largest of the giant gas planets, Jupiter, with a volume 1,300 times greater than Earth's, contains more than twice the mass of all the other planets combined. It is thought to be a gaseous and fluid planet without solid surfaces, Had it been somewhat more massive, Jupiter might have attained internal temperatures as high as the ignition point for nuclear reactions, and it would have flamed as a star in its own right. Jupiter and the other giant planets are of a low-density type quite distinct from the terrestrial planets: they are composed predominantly of such substances as hydrogen, helium, ammonia, and methane, unlike terrestrial planets. Much of Jupiter's interior might be in the form of liquid, metallic hydrogen. Normally, hydrogen is a gas, but under pressures of millions of kilograms per square centimeter, which exist in the deep interior of Jupiter, the hydrogen atoms might lock together to form a liquid with the properties of a metal. Some scientists believe that the innermost core of Jupiter might be rocky, or metallic like the core of Earth.Jupiter rotates very fast, once every 9.8 hours. As a result, its clouds, which are composed largely of frozen and liquid ammonia, have been whipped into alternating dark and bright bands that circle the planet at different speeds in different latitudes. Jupiter's puzzling Great Red Spot changes size as it hovers in the Southern Hemisphere. Scientists speculate it might be a gigantic hurricane, which because of its large size (the Earthcould easily fit inside it), lasts for hundreds of years.Jupiter gives off twice as much heat as it receives from the Sun. Perhaps this is primeval heat or heat generated by the continued gravitational contraction of the planet. Another starlike characteristic of Jupiter is its sixteen natural satellites, which, like a miniature model of the Solar System, decrease in density with distance — from rocky moons close to Jupiter to icy moons farther away. If Jupiter were about 70 times more massive, it would have become a star, Jupiter is the best-preserved sample of the early solar nebula, and with its satellites, might contain the most important clues about the origin of the Solar System.1. The word "attained获得，达到" in line 4 is closest in meaning to(A) attempted(B) changed(C) lost(D) reached2. The word "flamed" in line 5 is closest in meaning to(A) burned(B) divided(C) fallen(D) grown3. The word "they" in line 7 refers to(A) nuclear reactions(B) giant planets(C) terrestrial(D) substances4. According to the passage , hydrogen can become a metallic-like liquid when it is(A) extremely hot(B) combined with helium(C) similar to atmospheres(D) under great pressures5. According to the passage , some scientists believe Jupiter and Earth are similar in that they both have(A) solid surfaces(B) similar masses(C) similar atmospheres(D) metallic cores6. The clouds surrounding Jupiter are mostly composed of(A) ammonia(B) helium(C) hydrogen(D) methane7. It can be inferred from the passage that the appearance of alternating bands circling Jupiter is caused by(A) the Great Red Spot(B) heat from the Sun(C) the planet's fast rotation(D) Storms from the planet's Southern Hemisphere8. The author uses the word "puzzling" in line 17 to suggest that the Great Red Spot is(A) the only spot of its kind(B) not well understood(C) among the largest of such spots(D) a problem for the planet's continued existence9. Paragraph 3 supports which of the following conclusions?(A) Jupiter gives off twice as much heat as the Sun.(B) Jupiter has a weaker gravitational force than the other planets.(C) Scientists believe that Jupiter was once a star.(D) Scientists might learn about the beginning of the Solar System by Studying Jupiter.10. Why does the author mention primeval heat (lines 21)?(A) To provide evidence that Jupiter is older than the Sun(B) T o provide evidence that Jupiter is older than the other planets(C) To suggest a possible explanation for the number of satellites that Jupiter has(D) To suggest a possible source of the quantity of heat that Jupiter gives off11. According to the passage , Jupiter's most distant moon is(A) the least dense(B) the largest(C) warm on the surface(D) very rocky on the surface12. Which of the following statements is supported by the passage ?(A) If Jupiter had fewer satellites, it would be easier for scientists to study the planet itself.(B) If Jupiter had had more mass, it would have developed internal nuclear reactions.(C) If Jupiter had been smaller, it would have become a terrestrial planet.(D) if Jupiter were larger, it would give off much less heat答案：DABDD ACBDD AB。

Anyone ever heard of Proteous?Proteus was a God in Greek mythology who could change form.He could make himself look like a lion or a stone or a tree,anything you wanted,and he could go through a whole series of changes very quickly.Well,the octopus is the real world version of Proteus.Just like Proteus,the octopus can go through all kinds of incredible transformations.And it does this in three ways:by changing color,by changing its texture,and by changing its size and shape.For me,the most fascinating transformation is when it changes its color.It’s a normal skin color,the one it generally presents,is either red or brown or even grey,and it’s speckled with dark spots.But when it wants to blend in with its environment to hide from its enemies,it can take on the color of its immediate surroundings:the ocean floor,a rock,a piece of coral,whatever.Charles?Student：Do we know how that works,I mean,how they change colors?Professor：Well,we know that the reaction that takes place is not chemical in nature.The color changes are executed by two different kinds of cells in the octopus’skin,mainly by color cells on the skin’s surface call chromatophoresChromatophores consist of tiny sacks filled with color dye.There might be a couple hundred of these color sacks per square millimeter of the octopus’skin,and depending on the species,they can come in as many as five different colors.Each one of these sacks is controlled by muscles. If the muscles are relaxed,the sack shrinks,and all you see is a little white point.But if the muscle’s contract,then the sack expands,and you can see the colors.And by expanding different combinations Student：And just with various combinations of those five colors,they can recreate any color in their environment?Professor：Well,they can no doubt create a lot with just those five colors,but you are right,maybe they can’t mimic every color around them,so that’s where the second kind of cell comes in.Just below the chromatophores is a layer of cells that reflect light from the environment,and these cells help the octopus create a precise match with the colors surround them.The colors from the color sacks are supplemented with colors that are reflected from the environment,and that’s how they are able to mimic colors with such precision.So,that’s how octopus mimic colors.But they don’t just mimic the colors in their environment; they can alos mimic the texture of objects in their environment.They have these little projections on their skin that allow them to resemble various textures.The projections are called papillae6If the octopus wants to have a rough texture,it raises the papillae.If it wants to have a smooth texture,it flattens out the papillae, so it can acquire a smooth texture to blend in with the sandy bottom of the sea.So the octopus has the ability to mimic both the color and the texture of its environment.And it’s truly amazing how well it can blend in with its surroundings.You can easily swim within a few feet of an octopus and never see it.Student：I read that they often hide from predators by squirting out a cloud of ink,or something like that.Professor：Yes.The octopus can release a cloud of ink if it feels threatened.But it doesn’t hide behind it,as is generally believed.Um,the ink cloud is...it serves to distract a predator while the octopus makesits escape.Um,now there’s a third way that octopus can transform themselves to blend in withor mimic their environment,and that’s by changing their shape and size,well,at least their apparent size.The muscular system of the octopus enables it to be very flexible to assume all sorts of shapes and postures.So it can contract into the shape of a little round stone,and sit perfectly still on the seafloor.Or it can nestleup7in the middle of a plant and take the shape of one of the leaves.Even Proteus would be impressed,I think.教授：好的，现在我想讲一讲一种特别的动物，它有一套令人惊叹的防御机制——它就是章鱼，一种生活在大海之中的不凡之物。

下面是YJBYS店铺整理的2017年托福听力考试考场模拟训练附答案，欢迎参考!During the second half of the nineteenth century, the production of food and feed crops in the United States rose at an extraordinarily rapid rate. Corn production increased by four and a half times, hay by five times, oats and wheat by seven times. The most crucial factor behind this phenomenal upsurge in productivity was the widespread adoption of labor-saving machinery by northern farmers. By 1850 horse-drawn reaping machines that cut grain were being introduced into the major grain-growing regions of the country. Horse-powered threshing machines to separate the seeds from the plants were already in general use. However, it was the onset of the Civil War in 1861 that provided the great stimulus for the mechanization of northern agriculture. With much of the labor force inducted into the army and with grain prices on the rise, northern farmers rushed to avail themselves of the new labor-saving equipment. In 1860 there were approximately 80,000 reapers in the country; five years later there were 350,000.After the close of the war in 1865, machinery became ever more important in northern agriculture, and improved equipment was continually introduced. By 1880 a self-binding reaper had been perfected that not only cut the grain, but also gathered the stalks and bound them with twine. Threshing machines were also being improved and enlarged, and after 1870 they were increasingly powered by steam engines rather than byhorses. Since steam-powered threshing machines were costly items —running from $ 1,000 to $4,000 —they were usually owned by custom thresher owners who then worked their way from farm to farm during the harvest season. "Combines" were also coming into use on the great wheat ranches in California and the Pacific Northwest. These ponderous machines — sometimes pulled by as many as 40 horses — reaped the grain, threshed it, and bagged it, all in one simultaneous operation.The adoption of labor-saving machinery had a profound effect upon the sale of agricultural operations in the northern states — allowing farmers to increase vastly their crop acreage. By the end of century, a farmer employing the new machinery could plant and harvest two and half times as much corn as a farmer had using hand methods 50 years before.1. What aspect of farming in the United States in the nineteenth century does the passage mainly discuss?(A) How labor-saving machinery increased crop Production(B) Why southern farms were not as successful as Successful as northern farms(C) Farming practices before the Civil War(D) The increase in the number of people farming2. The word "crucial至关重要的`" in line 4 is closest in meaning to(A) obvious(B) unbelievable(C) important(D) desirable3. The phrase "avail利用 themselves" in line 11 is closest in meaning to(A) take care(B) make use(C) get rid(D) do more4. According to the passage , why was the Civil War a stimulus for mechanization?(A) The army needed more grain in order to feed the soldiers.(B) Technology developed for the war could also the used by farmers.(C) It was hoped that harvesting more grain would lower the price of grain.(D) Machines were needed to replace a disappearing labor force.5. The passage supports which of the following statements about machinery after the Civil War?(A) Many farmers preferred not to use the new machinery.(B) Returning laborers replaced the use of machinery.(C) The use of farm machinery continued to increase.(D) Poor-quality machinery slowed the pace of crop production.6. Combines and self-binding reapers were similar because each(A) could perform more than one function(B) required relatively little power to operate(C) was utilized mainly in California(D) required two people to operate7. The word "they" in line 19 refers to(A) grain stalks(B) threshing machines(C) steam engines(D) horses8. It can be inferred from the passage that most farmers did not own threshing machines because(A) farmers did not know how to use the new machines(B) farmers had no space to keep the machines(C) thresher owner had chance to buy the machines before farmers did(D) the machines were too expensive for every farmer to own9.

2017年托福复习资料模拟试题及答案（七）
Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth's ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and run off of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have unraveled cons of evolution and irrevocably redirected its course. Certainly, there have been periods in Earth's history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only .01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out. However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt — time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments. 1. What does the passage mainly discuss? (A) The causes of the extinction of the dinosaur (B) The variety of species found in tropical rain forests. (C) The impact of human activities on Earth's ecosystems (D) The time required for species to adapt to new environments 2. The word "critical⾄关重要的" in line 1 is closest in meaning to (A) negative (B) essential (C) interesting (D) complicated 3. The word "jolting使震惊" in line 5 is closest in meaning to (A) predicted (B) shocking (C) unknown (D) illuminating 4. The author mentions the reduction of the variety of species on Earth in line 12 to suggest that (A) new habitats can be created for species (B) humans are often made ill by polluted water (C) some species have been made extinct by human activity (D) an understanding of evolution can prevent certain species from disappearing 5. The author mentions all of the following as examples of the effect of humans oil the world's ecosystems EXCEPT (A) destruction of the tropical rain forests (B) habitat destruction in wetlands (C) damage to marine ecosystems (D) the introduction of new varieties of plant species 6. The author mentions the extinction of the dinosaurs in the second paragraph to emphasize that (A) the cause of the dinosaurs extinction is unknown (B) Earth's climate has changed significantly since the dinosaurs' extinction, (C) not all mass extinctions have been caused by human activity (D) actions by humans could not stop the irreversible process of a species' extinction 7. The word "magnitude" in line 20 is closest in meaning to (A) concern (B) determination (C) carelessness (D) extent 8. According to the passage , natural evolutionary change is different from changes caused by humans in that changes caused by humans (A) are occurring ata much faster rate (B) are less devastating to most species (C) affect fewer ecosystems (D) are reversible 9. With which of the following statements would the author be most likely to agree? (A) Human influence on ecosystems should not be a factor in determining public policy. (B) The extinction of a few species is an acceptable consequence of human progress. (C) Technology will provide solutions to problems caused by the destruction of ecosystems. (D) Humans should be more conscious of the influence they have on ecosystems 答案： CBBCD CDAD。

Questions 1-10Glacier National park in Montana shares boundaries with Canada, an American Indian reservation, and a national forest. Along the North Fork of the Flathead River, the park also borders about 17,000 acres of private lands that are currently used for ranching, timber, and agriculture. This land is an important part of the habitat and migratory routes for several endangered species that frequent the park. These private lands are essentially the only ones available for development in the region.With encouragement from the park, local landowners initiated a land-use planning effort to guide the future of the North Fork. The park is a partner in an interlocal agreement that calls for resource-managing agencies to work together and with the more than 400 private owners in the area. A draft plan has been prepared, with the objective of maintaining traditional economic uses but limiting new development that would damage park resources. Voluntary action by landowners, in cooperation with the park and the county, is helping to restrict small-lot subdivisions, maintain wildlife corridors, and minimize any harmful impact on the environment.The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that Congress would impose a legislative solution.Nevertheless, many local residents want to retain the existingcharacter of the area.Meetings between park officials and landowners have led toa dramatically improved understanding of all concerns.1.

It can be inferred from the passage that a major interest of the officials of GlacierNational Park is to(A) limit land development around the park(B) establish a new Park in Montana(C) influence national legislation(D) settle border disputes with Canada7. In lines 15-16, the author implies that landowners might be responding to environmentalconcerns for which of the following reasons?(A) They wish to stimulate economic growth.(B) They wish to improve their public image.(C) They have a tradition of cooperating with the government.(D) They fear federal legislation.8.
