Most people think of astronomers as people who spend their time in cold observatories peering through telescopes every night. In fact, a typical astronomer spends most of his or her time analyzing data and may only be at the telescope a few weeks of the year. Some astronomers work on purely theoretical problems and never use a telescope at all. You might not know how rarely images are viewed directly through telescopes. The most common way to observe the skies is to photograph them. The process is very simple. First, a photographic plate is coated with a light-sensitive material. The plate is positioned so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged, and published so that many people can study it. Because most astronomical objects are very remote, the light we receive from them is rather feeble. But by using a telescope as a camera, long time exposures can be made. In this way, objects can be photographed that are a hundred times too faint to be seen by just looking through a telescope.【生词摘录】1. observatory: n.[C]a special building from which scientists watch the moon, stars, weather etc 天文台;观象台;气象台2. peer: v. to look very carefully or hard, especially because you are having difficulty in seeing (尤指因看起来费劲而)凝视，盯着看3. theoretical: adj. of, relating to, or based on theory 理论的4. photographic: adj. connected with photographs, using photographs, or used in producing photographs 摄影的，摄影用的5. plate: n.

（完整版）老托听力93篇原文老托Part C精选93篇1Community service is an important component of education here at our university. We encourage all students to volunteer for at least one community activity before they graduate. A new community program called "One On One" helps elementary students who've fallen behind. You education majors might be especially interested in it because it offers the opportunity to do some teaching—that is, tutoring in math and English. You'd have to volunteer two hours a week for one semester. You can choose to help a child with math, English, or both. Half-hour lessons are fine, so you could do a half hour of each subject two days a week. Professor Dodge will act as a mentor to the tutors—he'll be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tutoring next week. I'm sure you'll enjoy this community service and you'll gain valuable experience at the same time. It looks good on your resume, too, showing that you've had experience with children and that you care about your community. If you'd like to sign up, or if you have any questions, stop by Professor Dodge's office this week.【生词摘录】/doc/0b6916605.html,ponent: n.［C］one of several parts that together make up a wholemachine or system （机器或系统的）零件；成分；组成部分2.tutor: n.［C］someone who teaches one pupil or a small group, and isdirectly paid by them 家庭教师，私人教师 v. to teach someone as a tutor 给…当家庭教师；指导3.mentor: n.［C］an experienced person who advises and helps a lessexperienced person 顾问，指导人，教练2I hope you've all finished reading the assigned chapter on insurance so that you're prepared for our discussion today. But, before we start, I'd like to mention a few things your text doesn't go into. It's interesting to note that insurance has existed in some form for a very long time. The earliest insurance policies were what we called bottomry contracts. They provided shipping protection for merchants as far back as 3000 B.C. In general, the contracts were often no more than verbal agreements. They granted loans to merchants with the understanding that if a particular shipment of goods was lost at sea, the loan didn't have to be repaid. Interest on the loans varied according to how risky it was to transport the goods. During periods of heavy piracy at sea, for example, the amount of interest and the cost of the policy went up considerably. So, you can see how insurance helped encourage international trade. Even the most cautious merchants became willing to risk shipping their goods over long distances, not to mention in hazardous weather conditions when they had this kind of protection available. Generally speaking, the basic form of an insurance policy has been pretty much the same since the Middle Ages. There are four points that were salient then and remain paramount in all policies today. These were outlined in chapter six and will serve as the basis for the rest of today's discussion. Can anyone tell me what one of those points mightbe?【生词摘录】1.insurance: n.［U］an arrangement with a company in which you pay themmoney each year and they pay the costs if anything bad happens to you, such as an illness or an accident 保险；the money that you pay regularly to an insurance company 保险费；the business of providing insurance 保险业2.bottomry: n.船舶抵押契约（如船舶损失，则债务取消），冒险借贷3.contract: n.［C］a formal written agreement between two or morepeople,which says what each person must do for the other 契约；合同4.loan: n.［C］an amount of money that you borrow from a bank etc（银行等的）贷款5.understanding: n.［C usually singular］a private, unofficial agreement（私底下、非正式的）协议，协定6.interest: n.［U］a charge made for borrowing money（借贷的）利息［+on］7.piracy: n. the crime of attacking and stealing from ships at sea海上抢劫，海盗行为8.cautious: adj. careful to avoid danger or risks小心的，谨慎的，慎重的9.hazardous: adj.危险的10.s alient: adj.formal the salient points or features of something are themost important or most noticeable parts of it 【正式】显著的，突出的11. paramount: adj. more important than anything else 至高无上的，最重要的3Located at the NASA Research Center in Iowa is a 5,000-gallon vat of water, and inside the tank is an underwater treadmill designed by Dava Newman, an aerospace engineer. For four years Newman observed scuba divers as they simulated walking on the Moon and on Mars on her underwater moving belt. She wanted to discover how the gravity of the Moon and of Mars would affect human movement. To do this, Newman attached weights to the divers and then lowered them into the tank and onto the treadmill. These weights were carefully adjusted so that the divers could experience underwater the gravity of the Moon and of Mars as they walked on the treadmill. Newman concluded that walking on Mars will probably be easier than walking on the Moon. The Moon has less gravity than Mars does, so at lunar gravity, the divers struggled to keep their balance and walked awkwardly. But at Martian gravity, the divers had greater traction and stability and could easily adjust to a pace of 1.5 miles per hour. As Newman gradually increased the speed of the treadmill, the divers took longer, graceful strides until they comfortably settled into an even quicker pace. Newman also noted that at Martian gravity, the divers needed less oxygen. The data Newman collected will help in the future design of Martian space suits. Compared to lunar space suits, Martian space suits will require smaller air tanks; and, to allow for freer movement, the elbow and knee areas of the space suits will also be altered.【生词摘录】1.gallon: n.AmE a unit for measuring liquids, equal to 3.785 litres【美】加仑（等于3.785升）2.vat: n.［C］a very large container for storing liquids such as whisky ordye,when they are being made（酿酒、盛染料用的）大缸，大桶3.tank: n.［C］a large container for storing liquid or gas（盛放液体或气体的）大容器4.treadmill: n.［C］a mill worked in the past by prisoners treading onsteps fixed to a very large wheel（过去用以惩罚犯人的）踏车5.aerospace: adj. involving the designing and building of aircraft and spacevehicles 航空和航天（器制造）的n.［U］the industry that designs and builds aircraft and space vehicles 航空和航天工业，航天工业6.scuba diving: n.［U］the sport of swimming under water while breathingthrough a tube connected to a container of air on your back 斯库巴潜泳，水肺潜泳（戴自携式潜水呼吸器潜泳）7.simulate: v. to make or produce something that is not real but has theappearance of being real 模仿，模拟8.Martian: adj. of or relating to the planet Mars火星的Welcome to Everglades National Park. The Everglades is a watery plain covered with saw grass that's home to numerous species of plants and wildlife. At one and a half million acres, it's too big to see it all today, but this tour will offer you a goodsampling. Our tour bus will stop first at Taylor Slough. This is a good place to start because it's home to many of the plants and animals typically associated with the Everglades. You'll see many exotic birds and, of course, our world famous alligators. Don't worry, there's a boardwalk that goes across the marsh, so you can look down at the animals in the water from a safe distance. The boardwalk is high enough to give you a great view of the saw grass prairie. From there we'll head to some other marshy and even jungle like areas that feature wonderful tropical plant life. For those of you who'd like a closer view of the saw grass prairie, you might consider renting a canoe sometime during your visit here. However, don't do this unless you have a very good sense of direction and can negotiate your way through tall grass. We'd hate to have to come looking for you. You have the good fortune of being here in the winter—the best time of year to visit. During the spring and summer, the mosquitoes will just about eat you alive! Right now they're not so bothersome,but you'll still want to use an insect repellent.【生词摘录】1.Everglades National Park:大沼泽地国家公园2.saw grass:克拉莎草；加州砖子苗3.acre: n.［C］a unit for measuring area, equal to 4,047 square metres英亩4.sampling: n. items selected at random from a population and used totest hypotheses about the population 取样，抽样，采样5.exotic: adj.approving seeming unusual and exciting because of beingconnected with a foreign country 【褒义】异国风情的，外国情调的：exotic birds 外国的奇异鸟类6.alligator: n.［C］a large animal with a long mouth and sharp teeth thatlies in the hot wet parts of the US and China 短吻鳄7.boardwalk: n.［C］AmE a raised path made of wood, usually built nextto the sea【美】（常在海滨）用木板铺成的小道8.prairie: n.［C］a wide open area of land in North America which iscovered in grass or wheat（北美洲的）大草原9.canoe: n.［C］a long light boat that is pointed at both ends and whichyou move along using a paddle 独木舟，小划子10.n egotiate: v. <口>成功通过，顺利越过11.m osquito: n.［C］a small flying insect that sucks the blood of peopleand animals 蚊子Thank you. It's great to see so many of you interested in this series on "Survival in Outer Space." Please excuse the cameras; we're being videotaped for the local TV stations. Tonight I'm going to talk about the most basic aspect of survival—the space suit. When most of you imagine an astronaut, that's probably the first thing that comes to mind, right? Well, without space suits, it would not be possible for us to survive in space. For example, outer space is a vacuum—there's no gravity or air pressure; without protection, a body would explode. What's more, we'd cook in the sun or freeze in the shade with temperatures ranging from a toasty300 degrees above to a cool 300 degrees below zero Fahrenheit. The space suit that NASA has developed is truly a marvel. This photo enlargement here is a life-size image of anactual space suit worn by astronauts on the last space shuttle mission. This part is the torso. It’s made of seven extremely durable layers. This thick insulation protects against temperature extremes and radiation. Next is what they call a "bladder" of oxygen that's an inflatable sac, filled with oxygen, to simulate atmospheric pressure. This bladder presses against the body with the same force as the Earth's atmosphere at sea level. The innermost layers provide liquid cooling and ventilation. Despite all the layers, the suit is flexible, allowing free movement so we can work. Another really sophisticated part of the space suit is the helmet. I brought one along to show you. Can I have a volunteer come and demonstrate?【生词摘录】1.videotape: v. to record a television programme, film etc ona videotape把（电视节目、电影等）录在录像（磁）带上2.vacuum: n.［C］a space that is completely empty of all gas, especiallyone from which all the air has been taken away 真空3.shade: n.［U］slight darkness or shelter from the direct light of the sunmade by something blocking it 荫，背阴处4.toasty: adj.AmE informal warm and comfortable【美，非正式】暖烘烘的，温暖舒适的5.Fahrenheit: n.［U］a scale of temperature in which water freezes at 32°and boils at 212°华氏温度6.marvel: n.［C］something or someone surprisingly useful or skillful, thatyou like and admire very much 十分有用（灵巧）的物（人）7.enlargement: n.［C］a photograph that has been printed again in alarger size 放大的照片8.life-size:又作life-sized，adj. a picture or model of something or someonethat is life-size is the same size as they are in real life 与实物（真人）大小一样的9.shuttle: n.［C］a spacecraft that can fly into space and return to Earth,10.m ission: n.［C］an important job done by a member of the airforce,army etc, especially an attack on the enemy 任务，使命11.t orso: n.［C］your body, not including your head, arms, or legs（头和四肢除外的）人体躯干12.durable: adj. staying in good condition for a long time even if used a lot耐用的13.i nsulation: n.［U］material used to insulate something, especially abuilding（尤指建筑物的）绝缘材料；the act of insulating something or the state of being insulated 隔绝14.e xtreme: n.［C］something that goes beyond normal limits, so that itseems very unusual and unacceptable 极端15.b ladder: n.［C］a bag of skin, leather, or rubber, for example inside afootball, that can be filled with air or liquid （可充气或充水的）囊；袋16.i nflatable: adj. an inflatable object has to be filled with air before you canuse it 须充气方可使用的，（需）充气的17.s ac: n.technical a part inside a plant or animal that is shaped like a bagand contains liquid or air 【术语】（动物或植物的）囊；液囊18.i nnermost: adj.formal furthest inside【正式】最里面的19.v entilation: n.［U］通风（ventilate: v. to let fresh air intoa room,building etc 使通风）20.h elmet: n.［C］a strong hard hat worn for protection by soldiers,motorcycle riders, the police etc 头盔，钢盔，安全帽21.demonstrate: v. to show or prove something clearly证明，论证，证实；toshow or describe how something works or is done 示范，演示；to march through the streets with a large group of people in order to publicly protest about something （为公开抗议某事）游行，示威；to show that you have a particular skill, quality, or ability 展示，表露出（某种技能、品质或能力）6Good evening. My name is Pam Jones, and on behalf of the Modern Dance club, I'd like to welcome you to tonight's program. The club is pleased to present the TV version of The Catherine Wheel, Twyla Tharp's rock ballet. This video version of the ballet has been even more successful with audiences than the original theater production. It includes some animation, slow motion, and stop-action freezes that really help the audience understand the dance. The title of the piece refers to Saint Catherine, who died on a wheel in 307 A.D. Nowadays, a Catherine wheel is also a kindof firework. It looks something like a pinwheel. Anyway, the dance is certainly full of fireworks! You'll see how Twyla Tharp explores one family's attempt to confront the violence in modern life. The central symbol of the work is a pineapple, but exactly what it represents has always created a lot of controversy. As you watch, see if you can figure it out. The music for this piece is full of the rhythmic energy of rock music. It was composed by David Byrne. Of the rock band Talking Heads? And the lead dancer in this version was Sara Rudner, who is perfectly suited to Tharp's adventurous choreography. Following the video, dance teacher Mary Parker will lead a discussion about the symbolism Ms. Tharp used. We hope you can stay for that. So, enjoy tonight's video and thank you for your support.【生词摘录】1.present: v. to give a performance in a theatre, cinema, etc, or broadcast aprogramme on television or radio 上演；演出；表演；播出（电视或广播节目）2.ballet: n.［C］a performance in which a special style of dancing andmusic tell a story without any speaking 芭蕾舞剧；芭蕾舞曲3.animation: n.［U］the process of making animated films动物片的制作4.wheel: n.［C］one of the round things under a car, bus, bicycle etc thatturn when it moves （汽车、公共汽车、自行车等的）车轮5.firework: n.［C usually plural］a small container filled with powder thatburns or explodes to produce coloured lights, noise, and smoke 烟火，烟花，焰火6.pinwheel: n.［C］a toy consisting of a stick with curved pieces of plasticat the end that turn around when they are blown 玩具风车（windmill, BrE）7.pineapple: n.［C,U］a large yellow-brown tropical fruit or its sweet juicyyellow flesh 菠萝，凤梨8.controversy: n.［C,U］a serious argument or disagreement, especially aboutsomething such as a plan or decision, that continues for a long time 争论；辩论；争议9.rhythmic:又作rhythmical, adj. having rhythm有节奏的10.a dventurous: adj.又作adventuresome,AmE【美】eager to go to newplaces and do exciting or dangerous things 喜欢冒险的，有冒险精神的；not afraid of taking risks or trying new things 敢作敢为的，大胆创新的a performance 编舞（艺术）；舞蹈设计12.s ymbolism: n.［U］the use of symbols to represent something象征主义（手法）In our lab today, we'll be testing the hypothesis that babies can count as early as five months of age. The six babies here are all less than six months old. You'll be watching them on closed circuit TV and measuring their responses. The experiment is based on the well-established observation that babies stare longer if they don't see what they expect to see. First, we're going to let two dolls move slowly in front of the babies. The babies will see the two dolls disappear behind a screen. Your job is to record, in seconds, how long the babies stare at the dolls when thescreen is removed. In the next stage, two dolls will again move in front of the babies and disappear. But then a third doll will follow. When the screen is removed, the babies will only see two dolls. If we're right, the babies will now stare longer because they expect three dolls but only see two. It seems remarkable to think that such young children can count. My own research has convinced me that they have this ability from birth. But whether they do or not, perhaps we should raise another question. Should we take advantage of this ability by teaching children mathematics at such a young age? They have great untapped potential, but is it good for parents to pressure young children?【生词摘录】1.hypothesis: n.plural hypotheses,［C］an idea that is suggested as apossible way of explaining a situation, proving an idea etc, which has not yet been shown to be true 假设，假说2.closed circuit television (TV): a system in which cameras send picturesto television sets that is used in many public buildings to protect them from crime 闭路电视3.well-established: adj. established for a long time and respected历史悠久且享有盛誉的4.untapped: adj. an untapped resource, market etc has not yet been used（资源、市场等）未开发的；未利用的Before starting our tour of Monticello, I'd like to give you some historical facts that might help you appreciate what you see today even more. Monticello was the very much loved home of Thomas Jefferson for over fifty years. Jefferson, who was, ofcourse, President, was also a great reader and language enthusiast. He read widely on different subjects, including architecture. He wasn't formally trained in architecture, but as a result of his study and observation of other buildings, he was able to help design and build the house. He chose the site himself, naming the estate "Monticello," which means "little mountain" in Italian. In fact, many of the ideas behind the design also came from the Italian architect Andrea Palladio, who lived in the sixteenth century and who had a great influence on the architecture of England. Jefferson, however, ignored one of Palladio's principles, that is, not to build in a high place. Monticello's elevation made the transportation of what was needed at the house—for example, food—especially difficult. But the view from the estate would not be as spectacular if Jefferson had followed Palladio's advice; there really is no boundary between the house and the nature around it, and so Jefferson was able to look out on his beloved state of Virginia from his wonderful vantage point. Now we'll go on to Jefferson's library.【生词摘录】1.Monticello:蒙提切娄2.appreciate: v. to understand how good or useful someone or something is欣赏，赏识，鉴赏3.enthusiast: n.［C］someone who is very interested in a particularactivity or subject 热衷于…的人4.estate: n.［C］a large area of land in the country, usually with one largehouse on it and one owner （在乡村附有宅地的）一大片私有土地，庄园5.elevation: n.［singular］a height above the level of the sea 海拔6.spectacular: adj. very impressive and exciting壮观的，精彩的，引人注目的7.vantage point: a good position from which you can see something（能观察某物的）有利位置Now that we've all introduced ourselves to the new members, let's get down to work. As the committee in charge of this year's tree-planting project, we have several items on our agenda. First, we have to review the budget. The president has informed me that the trustees have set aside $3,000 for the purchase of trees and our environmental T-shirt sale netted a profit of $1,500. Second, we have to finalize the choice of trees. As you know, we're working with Richardson's Nursery again this year since everyone seemed pleased with the work he did for us last year. Mr. Richardson has presented us with several choices within our price range that he thinks would meet our needs. He's sent us pictures of the trees for us to look at, but he wanted me to tell you that we're welcome to visit the nursery if we want to see the trees themselves. Lastly, we need to plan some kind of ceremony to commemorate the planting. Several ideas, including a garden party of some sort, have been suggested. So let's get on with it and turn to the first order of business.【生词摘录】1.item: n.［C］a single thing, especially part of a list, group, or set（尤指清单上、一群或一组事物中的）一项；一件；一条2.trustee: n.［C］a member of a group that controls the money of acompany,college, or other organization（公司、学院等的）理事，董事会成员/doc/0b6916605.html,: v.especially AmE to earn a particular amount of money as a profit after tax has been paid 【尤美】获得净收入，净赚4.finalize: v. to finish the last part of a plan, business deal etc 使（计划、交易等）确定，最后定下5.nursery: n.［C］a place where plants and trees are grown and sold苗圃（garden center,BrE）Welcome to the Four Winds Historical Farm, where traditions of the past are preserved for visitors like you. Today, our master thatchers will begin giving this barn behind me a sturdy thatched roof, able to withstand heavy winds and last up to a hundred years. How do they do it? Well, in a nutshell, thatching involves covering the beams or rafters, the wooden skeleton of a roof with reeds or straw. Our thatchers here have harvested their own natural materials for the job, the bundles of water reeds you see lying over there beside the barn. Thatching is certainly uncommon in the Untied States today. I guess that's why so many of you have come to see this demonstration. But it wasn't always that way. In the seventeenth century, the colonists here thatched their roofs with reeds and straw, just as they had done in England. After a while, though, they began to replace the thatch with wooden shingles because wood was so plentiful. And eventually, other roofing materials like stone, slate, and clay tiles came into use. It's a real shame that most people today don't realize how strong and long lasting a thatched roof is. In Ireland, where thatching is still practiced, the roofs can survive winds of up to one hundred ten miles per hour. That's because straw and reedsare so flexible. They bend but don't break in the wind like other materials can. Another advantage is that the roofs keep the house cool in the summer and warm in the winter. And then, of course, there's the roofs' longevity—the average is sixty years, but they can last up to a hundred. With all these reasons to start thatching roofs again, wouldn't it be wonderful to see this disappearing craft return to popularity?【生词摘录】1.thatcher: n.［C］someone skilled in making a roof from plant stalks orfoliage 盖屋顶者2.barn: n.［C］a large farm building for storing crops, or for keepinganimals in 谷仓，粮秣房，仓库，牲口棚；informal a large, plain building 【非正式】空荡荡的大房子3.withstand: v. to be strong enough to remain unharmed by something such asgreat heat or cold, great pressure etc 耐得住，承受住（酷热、严寒、高压等）4.in a nutshell:spoken used when you are stating the main facts aboutsomething in a short, clear way 【口】一言以蔽之，简括地说，用一句话概括5.beam: n.［C］a long heavy piece of wood or metal used in buildinghouses,bridges etc 梁，横梁6.rafter: n.［C usually plural］one of the large sloping pieces of wood thatform the structure of a roof 椽7.skeleton: n.［C］the most important parts of something, towhich moredetail can be added later 骨架，框架；梗概，纲要8.reed: n.［C］a type of tall plant like grass that grows in wet places芦苇9.straw: n.［U］the dried stems of wheat or similar plants that are used for（如麦秆等）10.c olonist: n.［C］someone who settles in a new colony开拓殖民地的居民，拓殖者11.s hingle: n.［C］one of many small thin pieces of building materials,especially wood, used to cover a roof or wall（覆盖屋顶或墙用的）木瓦；屋面板；墙面板12.slate: n.［U］a dark grey rock that can easily be split into flat thin pieces板岩，板石13.clay: n.［U］heavy sticky soil that can be used for making pots, bricks etc黏土14.t ile: n.［C］a flat square piece of baked clay or other material, used forcovering roofs, floors etc（屋顶、地板等上用的）瓷砖，地砖15.l ongevity: n.［U］formal long life【正式】长寿；technical the length of aperson or anima l’s life【术语】（人或动物的）寿命A lot of people in the United States are coffee drinkers. Over the last few years, a trend has been developing to introduce premium, specially blended coffees, known as "gourmet coffees" into the American market. Boston seems to have been thebirthplace of this trend. In fact, major gourmet coffee merchants from other cities like Seattle and San Francisco came to Boston, where today they're engaged in a kind of "coffee war" with Boston's merchants. They are all competing for a significant share of the gourmet coffee market. Surprisingly, the competition among these leading gourmet coffee businesses will not hurt any of them. Experts predict that the gourmet coffee market in the United States is growing and will continue to grow, to the point that gourmet coffee will soon capture half of what is now a 1.5-million-dollar market and will be an 8-million-dollar market by 1999. Studies have shown that coffee drinkers who convert to gourmet coffee seldom go back to the regular brands found in supermarkets. As a result, these brands will be the real losers in the gourmet coffee competition.【生词摘录】1.premium: adj. of high quality高级的，优质的2.blended: adj. combined or mixed together so that the constituent partsare indistinguishable 混合的3.gourmet: n.［C］someone who knows a lot about food and wine andwho enjoys good food and wine 美食家4.birthplace: n.［C usually singular］the place where someone was born,especially someone famous （尤指名人的）出生地；the place where something first started to happen or exist 发源地，发祥地You may remember that a few weeks ago we discussed the question of what photography is. Is it art, or is it a method of reproducing images? Do photographs belong in museums or just in our homes? Today I want to talk about a person who tried tomake his professional life an answer to such questions. Alfred Stieglitz went from the United States to Germany to study engineering. While he was there, he became interested in photography and began to experiment with his camera. He took pictures under conditions that most photographers considered too difficult. He took them at night, in the rain, and of people and objects reflected in windows. When he returned to the United States he continued these revolutionary efforts. Stieglitz was the first person to photograph skyscrapers, clouds, and views from an airplane. What Stieglitz was trying to do in these photographs was what he tried to do throughout his life: make photography an art. He felt that photography could be just as good a form of self-expression as painting or drawing. For Stieglitz, his camera was his brush. While many photographers of the late 1800's and early 1900's thought of their work as a reproduction of identical images, Stieglitz saw his as a creative art form. He understood the power of the camera to capture the moment. In fact, he never retouched his prints or made copies of them. If he were in this classroom today, I'm sure he'd say, "Well, painters don't normally make extra copies of their paintings, do they?" 【生词摘录】1.experiment: v. to try various ideas, methods etc to see whether they willwork or what effect they will have 试验；试用2.skyscraper: n.［C］a very tall modern city building摩天大楼3.identical: adj. exactly the same完全相同的［+to］4.capture: v. to succeed in showing or describing a situation or feelingusing words or pictures（用语言或图片）记录下5.retouch: v. to improve a picture or photograph by painting。

31Current studies show that what goes on labels is an important consideration for manufacturers, since more than seventy percent of shoppers read food labels when considering whether to buy a product. A recent controversy as to whether labels on prepared foods should educate or merely inform the consumer is over, and a consumer group got its way. The group had maintained that product labels should do more than simply list how many grams of nutrients afood contains. Their contention was that labels should also list the percentage of a day's total nutrients that theproduct will supply to the consumer, because this information is essential in planning a healthy diet. A government agency disagreed strongly, favoring a label that merely informs the consumer, in other words, a label that only lists the contents of the products. The agency maintained that consumers could decide for themselves if the food is nutritious and is meeting their daily needs. The consumer group, in supporting its case, had cited a survey in which shoppers were shown a food label, and were then asked if they would need more or less of a certain nutrient after eating a serving of this product. The shoppers weren't able to answer the questions easily when they were not given a specific percentage. This study, and others helped get the new regulation passed, and now food products must have the more detailed labels.【生词摘录】1. label: n.

I'm here today to talk to you about a career with our airline. We're especially interested in recruiting people to fill openings for flight attendants. First of all, to work as a flight attendant with us, you must be accepted into our training program and with so many people applying, it's not easy to be selected. From the thousands of applications that we receive annually, we choose fewer than a thousand people for training. So, we require experience serving the public; and it also helps if you've earned some college credits. Also, not everybody who gets accepted into the training program makes it through. The course meets six days a week for five weeks. The training includes extensive classroom work in such subjects as first aid and passenger psychology as well as practical training in flight procedures and meal service. A lot of our graduates say that our flight attendants develop the skills of a nurse, a headwaiter, and a public relations executive! But, as a flight attendant myself, I can say that all of the hard work is worth it. Of course, I get to travel throughout the country, and the airline pays all of my expenses while I'm away from my base station. And, what I like best of all is that I've made friends with people from all over the country!【生词摘录】1. airline: n.

老托福听力93篇（33-34）-TodayIwanttotalkabout老托福听力93篇(33-34)-T oday I want to talk about33Today I want to talk about the Earth's last major climatic shift, at the end of the last ice age. But first, let's back up a moment and review what we know about climatic change in general. First, we defined "climate" as consistent patterns of weather over significant periods of time. In general, changes in climate occur when the energy balance of the Earth is disturbed. Solar energy enters the Earth's atmosphere as light and is radiated by the Earth's surface as heat. Land, water, and ice each affect this energy exchange differently. The system is so complex that, to date, our best computer models are only crude approximations and are not sophisticated enough to test hypotheses about the causes of climatic change. Of course, that doesn't keep us from speculating. For instance, volcanic activity is one mechanism that might affect climatic change. When large volcanoes erupt, they disperse tons of particles into the upper atmosphere, where the particles then reflect light. Since less light is entering the system of energy exchange, the result would be a cooling of the Earth's surface. Of course, this is just one possible mechanism of global climate change. In all probability, a complete explanation would involve several different mechanisms operating at the same time.【生词摘录】1. climatic: adj. connected with the weather in a particular area 气候的2. ice age: one of the long periods of time, thousands of years ago, when ice covered many northern countries 冰川期，冰河时代3. consistent: adj. always having the same beliefs, behavior, attitudes, quality etc(信仰、行为、态度、品质等)一贯的，一致的;始终如一的4. disturb: v. to interrupt someone so that they cannot continue what they are doing by asking a question, making a noise etc 干扰，打扰;使中断5. radiate: v. if something radiates light or heat, or if light or heat radiates from something, it is sent out in all directions 辐射(光或热);(向四面八方)发射6. crude: adj. not developed to a high standard or made with great skill 粗制的7. approximation: n. [C]a number, amount etc that is not exact, but is almost correct 概算，近似值8. hypothesis: n. [C]plural hypotheses, an idea that is suggested as a possible way of explaining a situation, proving and idea etc, which has not yet been shown to be true 假设，假说9. speculate: v. to think or talk about the possible causes or effects of something without knowing all the facts or details 猜测，推测10. disperse: v. if something disperses or is dispersed, it spreads over a wide area(使)消散;(使)分散11. cooling: n.[U]the process of becoming cooler; a falling temperature 冷却34I know you're anxious to get your permits and get started. But there're just a few things I'd like to mention that might help you avoid trouble during your stay. First of all, make sure you carry adequate water. You'll need it if you're hiking, especially in this heat. A good rule of thumb is to bring one gallon per personper day this time of year. Don't try to rely on the park's natural springs to supply all your water needs. And please, do not use soap in the springs. It's your responsibility to protect the park's natural features. For those of you staying beyond the weekend, make sure that you set up camp well away from dry creekbeds. We may get some heavy rainfall, and those creekbeds could quicklybecome filled with water, and you and all your equipment might end up washed downstream. When you pick up your permits, you'll also get a park services booklet. It'll tell you everything you need to know about the hiking trails. They vary in length, of course, but most of them are under five miles—relatively easy day hikes. Remember, if you're hiking solo, make sure you let someone know you're going and when they can expect you back. And . . . uh, for your own safety, we recommend that you not climb rock faces. A lot of the rock throughout the park is very unstable. One final word: watch out for poisonous snakes. Rattlesnake activity is at its peak this time of year, especially at night. For your own good, we recommend wearing protective clothing and carry a flashlight after dark.【生词摘录】1. hike: v. to walk a long way in the mountains or countryside 徒步旅行，远足2. rule of thumb: a rough method of calculation, based on practical experience(根据实际经验的)粗略的计算方法3. gallon: n.

托福听力原文Conversation 1:Passage 1Man: Hi. Are you Paula?$ Woman: Jim?$ Man: Hi. Nice to meet you.$ Woman: Glad to meet you.$ Man: So, you need some tutoring in English?$ Woman: Yeah. I'm taking English composition, and I'm not doing very well on my essays.$ Man: Right. Um, well, first let's see if we can figure out a time to meet . . . that we're both free.$ Woman: Okay.$ Man: How about Mondays? Maybe in the morning? I don't have any classes until eleven on Mondays.$ Woman: That would work, but I was hoping we could, you know, meet more than once a week.$ Man: Oh. Well, Tuesdays are out. I've got classes and, uh, I work at the library part time on Tuesdays and Thursdays. Bu t I could get together on Wednesdays.$ Woman: In the morning?$ Man: Probably nine-thirty would be best. That way we'd have an hour to work before I'd have to get ready for my eleven o'clock.$ Woman: So that would be two hours a week then?$ Man: I could do that.$ Woman: Oh, but, would that be extra? You know, 2. would I need to pay you for the extra session连续授课时间?$ Man: No. Um, just so you meet me here at the LearningCenter, and we both sign in, then I'll get paid. Tutoring is free, to you, I mean. The school pays me. But we both have to show up.3 If you don't show up and sign in for a session, then I don't get paid. So . . .$ Woman: Oh, don't worry about that. I really need the help.I won't miss any sessions unless I'm sick or something.$ Man: Okay then. So you want me to help you with your essays?$ Woman: Right. I could bring you some that have, you know, comments on them. I'm getting C's and . . .$ Man: Well, that's not too bad. Once I see some of your writing, we should be able to pull that up （名次提前）to a B.$ Woman: You think so?$ Man: Sure. But I need to explain something. Some of my students in the past . . . they expected me to write their essays for them. But that's not what a tutor is supposed to do.4. My job is to help you be a better writer.$ Woman: Oh, I understand that. But you'll read my essays, right?$ Man: Oh yeah. No problem. We'll read them together, and I'll makesuggestions.$ Woman: Great. I think part of the problem is I just don't understand the teacher's comments. $ Maybe you can help me figure them out.$ Man: Sure. Who's the teacher?$ Woman: Simpson.$ Man: 5. No problem. I've tutored a couple of her students, so I know more or less where she's coming from. Okay, then. I guess we'll meet here on Monday.$ Woman: I'll be here. Nine-thirty you said.$ Man: Just sign in when you get here.Passage 2Professor:6. Okay, today we’re going to discuss the four major types of drainage patterns(排水系统).7. I trust you’ve already read the chapter so you’ll recall that a drainage pat tern is the arrangement of channels that carry water in an area. And these patterns can be very distinctive since they’re determined by the climate, the topography(地形学,地形测量学), and the composition of the rock that underlies the formations. So, consequently, we can see that a drainage pattern is really a good visual summary of the characteristics of a particular region, both geologically and climactically. In other words, when we look at drainage patterns, wecan draw conclusions about the structural formation and relief of the land as well as the climate.Now all drainage systems are composed of an interconnected network of streams, and, when we view them together, they form distinctive patterns. Although there are at least seven identifiable kinds of drainage patterns, for our purposes, we’re going to limit our study to the four major types. Probably the most familiar pat te rn is the dendritic (树枝状的) drainage pattern.8. This is a stream that looks like the branches of a tree. Here’s an example of a dendritic pattern. As you can see, it’s similar to many systems in nature. In addition to the structure of a tree, it also resembles the human circulation system. This is a very efficient drainage system because the overall length of any one branch is fairly short, and there are many branches, so thatallows the water to flow quickly and efficiently from the source or sources.$ O kay, let’s look at the next example.$ This drainage pattern is referred to as a radial(辐射状的) pattern. Notice how the streams flow from a central point. This is usually a high mountain, or a volcano. 9. It kind of looks like the spokes(辐条；) that radiate out from the hub(中心) of a wheel. When we see a radial pattern, we know that the area has experienced uplift and that the direction of the drainage is down the slopes of a relatively isolated centralpoint.$ Going back to the dendritic for a moment. The pattern is determined by the direction of the slope of the land, but it, uh, the streams flow in more or less the same direction, and . . . so it’s unlike the radial that had multiple directions of flow from the highest point.$ Now this pattern is very different from either the dendritic or the radial. $ This is called a rectangular (长方形的; 矩形的) pattern, and I think you can see why. Just look at all of those right-angle (直角) turns. The rectangle pattern is typical of a landscape that’s been formed by fractured joints and faults. And because this broken rock is eroded more easily than unbroken rock, stream beds are carved along the jointed bedrock.10 Finally we have the trellis (格架) pattern. And here in this example, you can see quite clearly how the tributaries (支流的)of an almost parallel structure drain into valleys and . . . and form the appearance of a garden trellis. This pattern forms in areas where there are alternating bands of variable resistance, and by that I mean that the bands of rock that are very strong and resistant to erosion alternate with bands of rock that are weakand easily eroded. This often happens when a horizontal(水平的), plain folds and outcroppings (出露地表) appear.$ So, as I said, as a whole, these patterns are dictated by the structure and relief of the land.$ The kinds of rocks on which the streams are developed, the structuralpattern of the folds(褶层), uh, faults, and . . . uplift will usually determine a drainage system. However, I should also mention that drainage patterns can occasionally appear to be, well, out of sync with the landscape. And this can happen when a stream flows over older structures that have been uncovered by erosion or . . . or when a stream keeps its original drainage system when rocks are uplifted. So when that happens, the pattern appears to be c ontrary to the expected course of the stream. 11. But I’m interested in your understanding the basic drainage systems. So I don’t plan to trick you with test questions about exceptional patterns, but I expect you to know that exceptions to the patterns can occur when geological events influence them.Passage 3Professor:$ Drawing is a very basic a rt form. It’s appealing because it can be used to make a very quick record of the ideas that an artist may be envisioning(imaginative), so, a drawing can serve as a visual aid for the artist to remember a certain moment of inspiration and maybe use it for a more detailed work later on. Okay, usually such sketches allow the artist to visualize the proportions and the shapes without much attention to details so these images can be used by painters, architects, sculptors—any artist really. And large renderings, sketches of parts of the whole . . . thesecan be helpful in the creative process when a . . . a huge image might be more difficult to conceive of in its entirety. Or, a sketch of just one face in a crowd can allow the artist to . . . focus on creating just that part of the image.So, in many artists’ studios, countless drawings are strewn about as the final painting or sculpture takes form. And this gives us insight into the creative process, as well the opportunity to see changes from the images at the beginning in the images of the finished work. It’s rare, in fact, for an artist to use permanent materials to begin a piece of art. And some painters, for example, even sketch onto the surface of the canvas before applying the pigments. 13. 14. Now, architects are especially prone to（be likely to）sketches because, of course, their buildings are so large that an image in smaller scale is necessary to the imagination and implementation of such projects. So, uh, these studies become the basis for future works. And again, this is very interesting as a record of the creative process. Okay so far? 1412. Okay, drawing has several other functions besides as a temporary reference. For centuries, artists have used drawing as a traditional method of education. By copying the great works, especially of the Old Masters, aspiring artists could learn a lot about proportion, how to capture light and shadow and . . . and so forth. In fact, some artists who later achieve recognition, still continue to use this practice to hone their skills or . . . or simply to pay homage to another artist, as is often the case whena work of art originally created in another medium like a sculpture . . . when it’s recreated in the form of a drawing. Many examples of drawings of Michelangelo’s sculptures were re-created by well-known artists. One that comes to mind is the Study of Michelangelo’s Bound Slave by Edgar Degas. Theoriginal by Michelangelo was a marble sculpture that was, oh, about seven feet in height, but the small drawing was made in a sketchpad. In any case, the study is also considered a masterpiece, on a small scale, of course.12. So . . . what additional purposes m ight be served by the medium of drawing?Well, let’s remember that photography is a relatively new art form, so prior to the use of photographs to record historical events, a quick drawing by an artist was about the only way to preserve a real-time visual account of an important moment. Although a more permanent visual impression might be rendered later, it would be based on memory and not on the artist’s actual observation. 15. Probably the most often cited example of a sketch t hat preserved a n historical record would be the small drawing of Marie Antoinette(玛丽安彤奈特) as she was taken to the guillotine(断头台) in a cart through the streets of Paris. Jacques-Louis David sketched this famous drawing on a piece of paper about the size of the palm of his hand. And the artist, the artist reporter, is still important even in modern times, when photography isn’t possible, for e xample, when judges won’t permit cameras in the courtroom.17. Ok ay, to review, we’ve talked abou t three functions for drawing—as a visual aid for the artist to complete a future work, as a method of educ ation f or aspiring artists or eve n practiced artists, and as a way to report an event. But the sketchbook has . . . other possibilities. $ Sometimes a drawing is the final execution of the art. Picasso produced hundreds of drawings in, well, every conceivable medium, but especially in pencil and crayon. I find it very interesting that Picasso did so much of this kind of work . . . drawing, I mean, in his last years. Some critics have argued thathe was just laughing at the art world, which was willing to pay outrageous sums for anything with his name on it, and clearly, a drawing can be executed in a short period of time. But others, other critics, 16. they feel as I do that Pi casso was drawing because it was so basic, and because it was so spontaneous and so much fun. And also, think about how difficult it really is to produce a quick drawing with a few lines and, uh, no opportunity to . . . to recreate the original, either by painting it out or remodeling the clay or changing the building materials, or . . . or any of the other methods for revision of a finished artistic work that artists have at their disposal. So, what I’m saying is that drawing when it’s elevated to a finished piece, it must be done with confidence and it must show a high degree of creativity and mastery of the art form. In a way, it harkens back to the beginnings of art itself, when some unknown artist must have stuck a finger in the earth to draw animage or . . . maybe he picked up a stone and made a drawing on the wall of a cave.Okay, so, as a first assignment, I want you to make a couple of sketches yourself. I’m not going to grade them. This isn’t a studio art class. I just want you to use a few basic strokes to capture an image. You can do the first one in pencil, crayon, ink, chalk, or even charcoal . . . whatever you like. Then, I want you to sketch the same image in a different medium. So, if you do a face in pencil, I want you to do the same face but in chalk or crayon. Bring them to class next week and we’ll continue our discussion of drawing, but we’ll talk more about the ma terials artists use to produce drawings, and, uh, we’ll refer to your sketches as examples.Passage 4Student: Thanks for seeing me, Professor Williams.Professor: Glad to, Alice. What do you have on your mind?Student:18. Well, I got a little mixed up when I started to go over my notes from the last class, so I had a few questions.Professor: Shoot.Student: Okay. I understand the three basic sources of personnel for multinational companies.That’s fairly self-explanatory.Professor: Host country, home country, and third country.Student: Right. But then you started talking about staffing patterns that . . . let me see . . . okay . . 19.. you said, “staffing pa tterns may vary depending on the length of time that t he multinational company has been operating,” and you gave some examples, but I got confused and now I can’t read my notes.Professor: Okay. Well, one pattern is to rely on home country managers to staff the key positions when the company opens, but gradually moving more host country nationals into upper management as the company grows.Student: So, for example, if a French company opened a factory in Canada, then French management would gradually replace themselves with Canadian managers. Is that what you mean?Professor: Right. I think I used that very example in class. So do you want to try to explain the second pattern to me?Student: Sure. 20.I think it’s the one where home country nationals are put in charge of the company if it’s located in a developed country, but in a developing country, t hen home country nationals manage the company sort of indefinitely.Professor: Right again. 20. And an example of that wouldbe . . . Student: . . . maybe using German management for a Swiss company in Germany, but, uh, they might send Swiss management to provideleadership for a Swiss company in . . . in . . .Professor: How about Zimbabwe?Student: This is one of the confusing parts.Zimbabwe has a very old and highly developed culture, so…Professor: . . . but it’s still defined as a developing country because of the economic base—which is being developed now.Student: Oh, okay.21. I guess that makes sense. Then the example of the American company with British management . . . when the company is in India . . . tha t would be a third-country pattern. Professor: Yes. In fact, this pattern is fairly prevalent among multinational companies in the United States.Many Scottish or English ma nagers have been hired for top management positions at United States subsidiaries in the former British colonies-India, Jamaica, the West Indies, some parts of Africa . . .Student: Okay. So I’ve got all the examples right now.$ Professor: Anything else?$ Student: Just one thing. There were some typical patterns for certain countries.$ Professor: Like the last example.$ Student: No. This came later in the lecture. Something about Japan and Europe.$ Professor: Oh. Right. I probably said that both Japanese multinationalcompanies and European companies tend to assign senior-level home country managers to 22. overseas locations for their entire careers, whereas multinational companies in the UnitedStates view overseas assignments as temporary, so they may actually find themselves reporting to a senior-level manager from the host country who has more experience.$ Student: So, for example, a Japanese company in the United States would most probably have senior-level Japanese managers with mid-level managers maybe from the United States. But in Japan, the senior-level Japanese managers at an American company would probably have mid-level American managers reporting to them?$ Professor: Well, generalities are always a little tricky, but for the most part, that would be a typical scenario. Because living as a permanent expatriate is a career move in Japan, but a temporary strategy in the United States.$ Student: Okay. That’s interesting.$ Professor: And important for you to know as a business major with an interest in international business.$ You’re still on that track, aren’t you?$ Student: I sure am. But, you know, I wasn’t thinking in terms of living abroad for my entire career.$ That really is a huge commitment, and something to ask about going in.Anyway, like you say, most American companies view overseas assignments as temporary. That’s more what I have in mind, for m yself, I mean.Passage 5 astronomy 天文学Professor:$ Okay, let’s get started. Um, as you know today I promised to take you on a walk through the sola r system, so let’s start here with the central object of our solar system—the Sun. As you can see, the Sun is about five inches in diameter an d that’sabout the size of a large grapefruit（柚子）, which is exactly what I’ve used to represent it here in our model. So, I’m going to take two steps and that will bring me to the planet closest to the Sun. That would be Mercury（水星）. Two more steps to Venus （金星）. And one step from Venus to Earth. Let’s continue walking three steps from Earth to Mars（火星）. And that’s as far as I can go here in the classroom, but we can visualize the rest of the journey.24. Don’t bother writing this down. Just stay with me on this. So, to go from Mars to Jupiter（木星）, we’d have to walk a little over half the length of a football field, so that would put us about at the library here on campus, and then to get from Jupiter to Saturn（土星）, we’d have to walk another 75 yards, so by then we’d be at Harmon Hall. From Saturn to Uranus（天王星）, we’d have to walk again as far as we’d gone in our journey from the Sun to Saturn, and so we’d probably be at the Student Union. From Uranus to Neptune（海王星）we’d have to walk the same distance again, which would take us all the way to the graduate dormitory towers. From Neptune to Pluto （冥王星）, another 125 yards. So, we’d en d up about one third of a mile from this classroom at the entrance to the campus.$ Okay. That’s interesting, but now I want you to think about the orbits of the planets in those locations. Clearly, the first four planets could orbit fairly comfortably in this room, but to include the others, we’d have to occupy an area of more than six-tenths of a mile, which is all the way from College Avenue to Campus Drive. Remember that for this scale, the Sun is five inches, and most of the planets are smaller than the lead on a sharpened pencil. Okay, with that in mind, I want you to think about space. Sure, there are some moons around a few planets, and ascattering of asteroids and comets, but really, there isn’t a lot out there in such a vast area. It’s, well, it’s pretty empty. And that’s what I really want to demonstrate with this exercise.Now, it would really be even more impressive if you could actually make that walk, and actually you can, if you visit Washington, D.C., where a scale model is set up on the National Mall, starting at the National Air and Space Museum and ending up at the Arts and Industries Museum. I did that a couple of years ago, and it was, well amazing. Even though Iknew the distances intellectually, there’s nothing like the experience. Has anybody else done that walk?$ Student 1:$ I have. And you’re right. It’s an eye-opener. It took me about twenty minutes to go from the Sun to Pluto because I stopped to read the information at each planet, but when I made the return trip, it was about ten minutes.$ Professor: Did you take pictures?$ Student 1: I didn’t. But, you know, I don’t think it would ha ve captured it anyway.25. Professor:$ I think you’re right. What impressed me about doing it was to see what was not there. I mean, how much space was between the bodies in the solar system. And a photograph wouldn’t have shown that.So back to our model. Here’s another tho ught for you. The scale for our model is 1 to 10 billion. Now, let’s suppose that we want to go to the nearest star system, the neighbor to our solar system. That would be the Alpha Centauri system, which is a little less than four and a half light years a way. Okay. Let’s walk it on our model. Here we are on the East Coast of the United States.So if we want to make it all the way to Alpha Centauri, we have to hike all the way to the West Coast, roughly a distance of 2,700 miles. And that’s just the closest one.$ To make a model of the Milky Way Galaxy would require a completely different scale because . . . because the surface of the Earth wouldn’t be large enough to accommodate a model at the scale of 1 to 10 billion. Now, let’s stop here for a minute because I just want to be sure that we’re all together on the terms solar system and galaxy. 26. Remember that our solar system is a single star, the Sun, with various bodies orbiting around it—nine planets and their moons, and asteroids, comets, meteors. But the galaxy has a lot of star systems—probably 100 billion of them.Okay? This is important because you can be off by almost 100 billion if you get confused by these terms. Not a good idea. Okay, then, even if we could figure out a different scale that would let us make a model of the Milky Way Galaxy, even then, it would be challenging to make 100 billion stars, which is what you’d have to do to complete the model. How many would that be exactly? Well, just try to count all the grains of sand on all the beaches on Earth. That would be about 100 billion. But of course, you couldn’t even count them in your lifetime, could you? I f you’d started counting in 1000 B.C.E. you’d be finishing just about now, with the counting, I mean. But of course, that assumes tha t you wouldn’t sleep or take any breaks.27. So, what am I hoping for from this lecture? What do you think I want you to remember?$ Student 2: Well, for one thing, the e normous distances . . .$ Student 3: . . . and the vast emptiness in space.$ Professor:$ That’s good. I hope that you’ll also begin to appreciatethe fact that the Earth isn’t the center of the universe.$ Our planet, although it’s very beautiful and unique, it’s still just one planet, orbiting around just one star in just one galaxy.Passage 6Professor:$ Okay, we know from our earlier study of Freud that29. defense mechanisms protect us from bringing painful thoughts o r feelings to the surface of our consciousness. We do this because our minds simply can’t tolerate these thoughts. So, defense mechanisms help us to express these painful thoughts or feelings in another way, while we repress the real problem. The function of defense mechanisms is to keep from being overwhelmed. Of course, the avoidance of problems can result in additional emotional issue s. And there’s a huge distinction between repression and suppression. Anybody want to explain the difference? $ Student 1:$ I’ll try it. 30. I think repression is an unconscious response to serious events or images but suppression is more conscious and deals with something unpleasant but not usually, well, terrible experiences.$ Professor:$ I couldn’t have said it better. Now remember that the thoughts or feelings that we’re trying to repress may include, just to mention a few, anger, depression, competition, uh . . . fear, envy, hate, and so on.$ For instance, let’s suppose that you’re very angry with your professor.31. N ot me, of cou rse. I’m referring to another professor. So, you’re very angry because he’s treated you unfairly insome way that . . . that could cause you to lose your scholarship. Maybe he failed you on an examination that didn’t really cover the material that he’d gone over in class, and an F grade in the course is going to be unacceptable to your sponsors. So, this wou ld be very painful, as I’m sure you’d agree. And I’d say it would qualify as a serious event.$ So let’s take a look a t several different types of defense mechanisms that you might employ to repress the feelings of disappointment, rage perhaps, and . . . a nd even violence that you’d feel toward the professor. Most of them are named so the mechanism is fairly obvious and one of the most common mechanisms is denial, which is . . .$ Student 2: If I want to deny something, I’ll just say I’m not angry with the professor.$ Professor:$ Exactly. You may even extend the denial to include the sponsors, and you could tell your friends that they’d never revoke your scholarship. And。

The designation of an areas 5) a marine sanctuary indicates that it is a protected area, just as a national park is. Peopleare permitted to visit and observe there, but living organisms and their environments may not be harmed or removed.The National Marine Sanctuaries Program is administered by the National Oceanic and Atmospheric Administration, a branch of the United States Department of Commerce.10) Initially, 70 sites were proposed as candidates for sanctuary status. Two and a half decadeslater, only fifteen sanctuaries had been designated, with half of these established after1978. They range in size from the very small (less than I square kilometer) Fagatele Bay National Marine Sanctuary in American Samoa to the Monterey Bay National MarineSanctuary in California, extending over 15,744 square kilometers.15) The National Marine Sanctuaries Program is a crucial part of new managementpractices in which whole communities of species, and not just individual species, areoffered some degree of protection from habitat degradation and overexploitation. Only in this way can a reasonable degree of marine species diversity be maintained in a setting that also maintains the natural interrelationships that exist among these species.20) Several other types of marine protected areas exist in the United States and othercountries. The National Estuarine Research Reserve System, managed by the UnitedStates government, includes 23 designated and protected estuaries. Outside the United States, marine protected-area programs exist as marine parks, reserves, and preserves.Over 100 designated areas exist around the periphery of the Carbbean Sea. Others range 25) from the well-known Australian Great Barrer Reef Marine Park to lesser-known parksin countries such as Thailand and Indonesia, where tourism is placing growing pressures on fragile coral reef systems. As state, national, and international agencies come torecognize the importance of conserving marine biodiversity, marine projected areas.whether as sanctuaries, parks, or estuarine reserves, will play an increasingly important role in preserving that diversity.1.

With only an apprentice asan assistant, the rural artisan provided the neighborhood with common goods from furniture to shoes to farm equipment in exchange for cash or for “goods in kind” from the customer’s第 9 页共 17 页field, pasture, or dairy. Sometimes artisans transformed material provided by the customer wove cloth of yam spun at the farm from the wool of the family sheep; made chairs or tables 10) from wood cut in the customer’s own woodlot; produced shoes or leather breeches fromcow, deer, or sheepskin tanned on the farm.Like their farming neighbors, rural artisans were part of an economy seen, by one historian, as “an orchestra conducted by nature.” Some tasks could not be done in the winter, other had to be put off during harvest time, and still others waited on raw materials that were 15) only produced seasonally. As the days grew shorter, shop hours kept pace, since few artisanscould afford enough artificial light to continue work when the Sun went down. To the best of their ability, colonial artisans tried to keep their shops as efficient as possible and toregularize their schedules and methods of production for the best return on their investment in time, tools, and materials, While it is pleasant to imagine a woodworker, for example, 20) carefully matching lumber, joining a chest together without resort to nails or glue, andapplying all thought and energy to carving beautiful designs on the finished piece, the time required was not justified unless the customer was willing to pay extra for the quality—and few in rural areas were, Artisans, therefore, often found it necessary to employ asmany shortcuts and economics as possible while still producing satisfactory products.10.

(A) To enable them to produce high qualityproducts(B) To enable them to duplicate an item manytimes(C) To impress their customers(D) To keep expenses low15. The phrase “resort to” in line 20 is closest in meaning to(A) protecting with(B) moving toward(C) manufacturing(D) using16. The word “few’ in lines 23 refers to第 10 页共 17 页(A) woodworkers(B) finished pieces(C) customers(D) chests17. It can inferred that the artisans referred to inthe passage usually produced products thatwere(A) simple(B) delicate(C) beautifully decorated(D) exceptionally long-lastingQuestions 18-28Cities develop as a result of functions that they can perform. Some functions result directly from the ingenuity of the citizenry, but most functions result from the needs of the local area and of the surrounding hinterland (the region that supplies goods to thecity and to which the city furnishes services and other goods). Geographers often make 5) a distinction between the situation and the site of a city. Situation refers to the generalposition in relation to the surrounding region, whereas site involves physicalcharacteristics of the specific location. Situation is normally much more important tothe continuing prosperity of a city. if a city is well situated in regard to its hinterland, its development is much more likely to continue. Chicago, for example, possesses an almost 10) unparalleled situation: it is located at the southern end of a huge lake that forces east-westtransportation lines to be compressed into its vicinity, and at a meeting of significant land and water transport routes. It also overlooks what is one of the world’s finest largefarming regions. These factors ensured that Chicago would become a great city regardless of the disadvantageous characteristics of the available site, such as being prone to flooding 15) during thunderstorm activity.Similarly, it can be argued that much of New York City’s importance stems from its early and continuing advantage of situation. Philadephia and Boston both originated at about the same time as New York and shared New York’s location at the western end of one of the world’s most important oceanic trade routes, but only New York possesses an 20) easy-access functional connection (the Hudson-Mohawk lowland) to the vast Midwesternhinterland. This account does not alone explain New York’s primacy, but it does include several important factors. Among the many aspects of situation that help to explain why some cities grow and others do not, original location on a navigable waterway seemsparticularly applicable. Of course, such characteristic as slope, drainage, power25) resources, river crossings, coastal shapes, and other physical characteristics help todetermine city location, but such factors are normally more significant in early stagesof city development than later.第 11 页共 17 页18. What does the passage mainly discuss?(A) The development of trade routes throughUnited States cities(B) Contrasts in settlement patterns in UnitedStates(C) Historical differences among three largeUnited States cities(D) The importance of geographical situation in the growth of United States cities19.

We’ll be seeing much of his work today. Wood was born in 1881 in Iowa farm country, and became interested in art very early in life. Although he studied art in both Minneapolis and at the Art Institute of Chicago, the strongest influences on his art were European. He spent time in both Germany and France and his study there helped shape his own stylized form of realism. When he returned to Iowa, Wood applied the stylistic realism he had learned in Europe to the rural life he saw around him and that he remembered from his childhood around the turn of the century. His portraits of farm families imitate the static formalism of photographs of early settlers posed in front of their homes. His paintings of farmers at work, and of their tools and animals, demonstrate a serious respect for the life of the Midwestern United States. By the 1930's, Wood was a leading figure of the school of art called "American regionalism." In an effort to sustain a strong Midwestern artistic movement, Wood established an institute of Midwestern art in his home state. Although the institute failed, the paintings you are about to see preserve Wood's vision of pioneer farmers....以上就是整理的“老托福听力93篇下载(文本+翻译)”，希望通过这些听力真题的练习，能够帮助大家更好的来备考托福考试 !相关字搜索：老托福听力93篇。

老托福听力93篇（27-28）第一篇：老托福听力93篇(27-28)老托福听力93篇(27-28)-It seems like only yesterdayIt seems like only yesterday that I was sitting where you are, just finishing my first year of medical school and wondering if I'd ever get a chance to use all my new knowledge on a real live patient!Well, I have good news for you!You don't have to wait until your third or fourth year of medical school to get some hands-on experience!The dean has invited me here to tell you about the university's rural opportunity program.If you enroll in this program, you can have the opportunity this summer, after your first year of medical school, to spend from four to six weeks observing and assisting a real physician like me in a small rural community.You won't have to compete with other students for time and attention, and you can see what life as a country doctor is really like.The program was designed to encourage medical students like yourselves to consider careers in rural communities that are still understaffed.It seems that medical students are afraid to go into rural family practice for two reasons.First, they don't know much about it.And second, specialists in the cities usually make more money.But, on the up-side, in rural practice, doctors can really get to know their patients and be respected members of the community.I participated in the program when it first started and spent six weeks in a small rural town.Let me tell you, it was really great!I got to work with real patients.I watched the birth of a child, assisted an accident victim, and had lots of really practical hands-on experience—all in one summer.And to my surprise, I found that country life has a lot to offer that city life doesn't—no pollution or traffic jams, forinstance!My experience made me want to work where I'm needed and appreciated.I don't miss the city at all!【生词摘录】1.live: adj.not dead or artificial;living 活的;非人造的;有生命的2.hands-on: adj.providing practical experience of something by letting people do it

schedule with you.Because I'm presenting a paper at a conference in Detroit on Thursday, I won't be here for either Wednesday's or Friday's class.I will, however, be here for Monday's.Next Friday, a week from today, is the midterm exam, marking the halfway point in the semester.Professor Andrews has agreed to administer the exam.In place of the usual Wednesday class, I've arranged an optional review session.Since it is optional, attendance will not be taken;however, attending the class wouldbe a good idea for those worried about the midterm.So, remember: optional class next

take for granted the wide variety of music available on the radio.But, this wasn't always the case.In the early days of radio, stations were capable of broadcasting only a narrow range of sounds, which was all right for the human voice but music didn't sound very good.There was also a great deal of crackling and other static noises that further interfered with the quality of the sound.A man named Edwin Armstrong, who was a music lover, set out to change this.He invented FM radio, a technology that allowed stations to send a broad range of frequencies that greatly improved the quality of the music.Now, you'd think that this would have made him a millionaire;it didn't.Radio stations at that time had invested enormous amounts of money in the old technology.So the last thing they wanted was to invest millions more in the new technology.Nor did they want to have to compete with other radio stations that had a superior sound and could put them out of business.So they pressured the Federal Communications Commission, the department of the United States government that regulates radio stations, to put restrictive regulations on FM radio.The result was that its use was limited to a very small area around New England.Of course as we all know, Edwin Armstrong's FM technology eventually prevailed and was adopted by thousands of stations around the world.But this took years of court battles and he never saw how it came to affect the lives of almost everyone.【生词摘录】1.crackling: n.[C]爆裂声2.static: adj.静电的3.FM: 调频(frequency modulation)4.frequency: n.[C]频率lionaire: n.[C]百万富翁，大富豪6.restrictive: adj.限制性的7.regulation: n.规则，规章8.prevail: v.流行，盛行，获胜，成功9.adopt: v.采用I'm going to talk about a train that exemplifies the rise and fall of passenger trains in the United States: the Twentieth Century Limited.Let me go back just a bit.In 1893, a special train was established to take people from New York to an exposition in Chicago.It was so successful that regular service was then set up between these cities.The inaugural trip of the Twentieth Century Limited was made in 1902.The train was different from what anyone had ever seen before.It was pulled by a steam engine and had five cars: two sleepers, a dining car, an observation car, and a baggage car, which, believe it or not, contained a library.The 42 passengers the train could carry were waited on by a large staff.There were even secretaries and a barber on board.It wasn't long before people had to wait two years to get a reservation.As time passed, technical improvements shortened the trip by a few hours.Perhaps the biggest technological change occurred in 1945, the switch from steam to diesel engines.By the 1960's, people were traveling by car and airplane.Unfortunately, the great old train didn't survive until the end of the century it was named for.【生词摘录】1.exemplify: v.例证，例示，作为……例子2.exposition: n.[C]博览会，展览会3.inaugural: adj.最早的，开始的4.sleeper: n.[C](火车等的)卧铺5.observation car:

老托福听力PartC原文1Scientists are always on the lookout for alternative sources of energy.科学家总是在查找替代能源。
Today were going to discuss one thats so plentiful they say it could supply more energy than all the coal and oil in the world.今日我们将探讨一种如此充分的，他们说能够供应比世界上全部的煤炭和石油更多的能量。
Its found in something called gas hydrate and, believe it or not, thats a kind of ice.它被发觉于某种叫做气体水合物(的东东)而且，信不信由你，那是一种冰。
Thats right. But the water in this ice was way down below the Earths surface when it was frozen, so it was under a lot of pressure.是的，但是在这种冰里的水在当它结冰时会降到地球表面下很深(的地方)，所以它会在很大的压力之下(所以压力很大)。
And trapped inside the crystals of ice are individual molecules of methane --- thats whats in natural gas.被困在冰的晶体中的是单个的甲烷分子——这就是自然气。
All this makes gas hydrate pretty strange stuff.全部这些(状况)使得气体水合物(成为)很诡异的东西。
托福听力经典加试题神经元细胞
托福听力经典加试题：神经元细胞托福听力经典加试题第五篇：神经元细胞介绍神经胶质细胞Biology Class女Professor:好，在今天开始讲课之前，我们先review一下上节课的内容。
上节课，我们讲了(We have talked about)神经元细胞(电脑中心的框中打又：Neutron), 以及其工作的原理(function), 有谁能回忆起来?在大脑运作的过程中起作用的一种细胞cell，它接受electronic signal, 经过传递，然后再送往大脑的接收器receptor. 〞女Professor突然打断(重听题)：“好的。
Bernard，可以了。
你的答案很complete.〞那么今天，我们来讲一下glial cell (电脑中央打出)，这也是大脑物质中的一种。
Historically, 历史上，生物学家不重视glial cell, 对神经传导的研究仅限于neuron(神经元)，也叫nerve cell。
神经传导通过electrical communication 从一个结点传到另一个结点，神经元被认为起主要作用，glial cell研究的很少，一直被忽略，被看作help the growth of neurons (出题)，起辅助作用(support neutron)。
例如，(以前biologists认为)glial cell的作用是protect, repaire the damaged neutron cell) 后来偶然发现大脑中glial cell比neuron的数目多很多，glial cell引起了科学家的重视，开始研究它究竟起什么作用(此处出题，问glial cell 怎么引起科学家注意的)。
(However, scientists accidentally discover that glial’s amount is far overnumber the number of the neuron. So glial attract people’s attention. )人们发现胶质细胞也有传导信息的作用，不过不是通过生物电(not electronically communication)，而是化学物质传导(but chemical communication)。

73Look at our topographical map and you'll see that the middle third of the North American continent from the Rocky Mountains almost to the Mississippi River is pretty flat. This is the Great Plains. This kind of area is sometimes called a prairie, sometimes a steppe. That's s-t-e-p-p-e. The defining features are level terrain, dry climate, and an absence of trees. The Great Plains are actually the former bed of a shallow inland sea. Over millions of years, sediment left by glaciers, water, and wind smoothed out the dry sea bed. As I said, the Great Plaints are bordered on the west by the Rocky Mountains. And it's really the Rockies that are responsible for the formation of the grasslands. The mountains are so high that they block the heavy moist air traveling eastward form the Pacific Ocean. Lighter, drier air passes over the mountains. Until people intervened with irrigation and farms, only grass could grow on the dry, windy plain. In fact, we can divide the Great Plains into three zones. In the west, where it's driest and windiest, the grass is very short. In the eastern zone, there's more rain and grass grows as high as 360 centimeters. In the middle third, there's a mix of grass species that grow to an intermediate height.【生词摘录】1. topographical: adj. 地形学的2. prairie: n. [C]大草原，牧场3. steppe: n. [C]大草原，干草原4. level: adj. 平坦的5. terrain: n. 地形6. sediment: n. [C]沉淀物7. glacier: n. [C]冰川8. smooth out: v. 消除，使平滑9. moist: n.

Moods sort of drift from person to person unconsciously. Slight, unintentional signals carry the mood. You've probably experienced it yourself. You're around someone who's feeling down and showing it—slumped shoulders, downcast mouth, subdued voice—all that sort of thing. Pretty soon you begin to feel depressed too. Of course, good moods are also catching, not just bad ones. Moods spread in steps. One person's facial expression or whatever is observed by another, who then unconsciously begins to mimic. The process is automatic—a split second mimicry. The person isn'teven aware of the copying. A full-blown case of mood transfer develops as this copying continues. Not everyone picks up moods to the same degree. Those who're most susceptible often have strong physiological responses to what's going on around them. You know, people who break out in a nervous sweat easily and whose stomachs churn. People don't all send moods equally well either. The best mood senders are expressive people because mood contagion can't happen without signals. If they aren't there—that is, the person gives no indication of the mood they're in—nobody will pick up the mood.【生词摘录】1. virus: n. [C]病毒2. contagious: adj. 传染性的3. unconsciously: adv. 无意地，不知不觉4. slight: adj. 微小的5. unintentional: adj. 不是故意的，无心的，无意识的6. slumped: adj. 耷拉着的7. downcast: adj. 气馁的，沮丧的8. subdued: adj. 被抑制的9. catching: adj. 能传染的10. mimic: v. 模仿，仿效11. a split second: 一瞬间12. mimicry: n. [C]模仿13. full-blown: adj. 全面的14. susceptible: adj. 易受影响的15. physiological: adj. 生理学的16. sweat: v. 出汗17. churn: v. 产生剧烈搅动18. contagion: n. [C]传染19. indication: n. [C]迹象，指示，暗示When you are old and grey and full of sleep,And nodding by the fire, take down this book, And slowly read, and dream of the soft look Your eyes had once, and of their shadows deep; How many loved your moments of glad grace, And loved your beauty with love false or true, But one man loved the pilgrim soul in you,And loved the sorrows of your changing face; And bending down beside the glowing bars, Murmur, a little sadly, how love fledAnd paced upon the mountains overheadAnd hid his face amid a crowd of stars.The furthest distance in the worldIs not between life and deathBut when I stand in front of youYet you don't know thatI love you.The furthest distance in the worldIs not when I stand in front of youYet you can't see my loveBut when undoubtedly knowing the love from both Yet cannot be together.The furthest distance in the worldIs not being apart while being in loveBut when I plainly cannot resist the yearningYet pretending you have never been in my heart. The furthest distance in the worldIs not struggling against the tidesBut using one's indifferent heartTo dig an uncrossable riverFor the one who loves you.。

Since we've been discussing alternative fuels lately, I wanted to pass on to you some information I read about a new fuel that's been in the news a lot lately.It's called A-21.It's composed of water and a chemical known as naphtha.It seems to be a very promising fuel because it's much cleaner than the gasoline that we use today.That's not to say that it doesn't pollute, but it is cleaner.A-21 isn't like some other alternative fuels that require completely new types of engines.A-21 still works in regular, everyday combustion engines—like the ones in cars—with only minor mechanical modifications.So changing over wouldn't be a big deal.You may doubt some of these claims as many researchers have.Some people feared that because it contains about 45 percent water it would freeze in the winter.But a small amount of antifreeze was added to it, and that seems to have solved the problem.A-21 has recently undergone street tests in buses in Reno, Nevada.So far it seems to work just

of many modern art movements.He's worked in Pop Art, Cubism, and Conceptual Art, but he made his mark as a pioneer in computer art.Even long before computers became popular, he was punching cards and feeding them into the big mainframe computer at Ohio State University.In the beginning, he had to work without a monitor, so he was virtually creating art in the dark.He even learned computer programming so he could experiment with this new tool.Through the computer, Csuri has been able to explore a new world of possibilities.For example, the computer enables him to sculpt in three dimensions.Also, he can look at a sculpture from any angle, and move it around, change the location of the light source, or he can copy it in different colors.Over the years, Csuri received numerous grants for various projects.This money allowed him to train students in computer graphics and animation techniques, and to advance the computer as a medium for artists.Even though he uses modern technology, Csuri still insists he is creating art.He's always told his students to keep the issues of art in focus, and not get so caught up in the technology that you forget about the image.【生词摘录】1.punch: v.打孔2.mainframe: n.主机，大型机3.monitor: n.[C]显示器4.sculpt: v.雕刻5.grant: n.[C]基金的赠予6.graphics: n.[C]图形，图像7.animation: n.[C]动画片制作第二篇：老托福听力101-1501.Which of the following best describes

news for you!You don't have to waituntil your third or fourth year of medical school to get some hands-on experience!The dean has invited me here to tell you about the university's rural opportunity program.If you enroll in this program, you can have the opportunity this summer, after your first year of medical school, to spend from four to six weeks observing and assisting a real physician like me in a small rural community.You won't have to compete with other students for time and attention, and you can see what life as a country doctor is really like.The program was designed to encourage medical students like yourselves to consider careers in rural communities that are still understaffed.It seems that medical students are afraid to go into rural family practice for two reasons.First, they don't know much about it.And second, specialists in the cities usually make more money.But, on the up-side, in rural practice, doctors can really get to know their patients and be respected members of the community.I participated in the program when it first started and spent six weeks in a small rural town.Let me tell you, it was really great!I got to work with real patients.I watched the birth of a child, assisted an accident victim, and had lots of really practical hands-on experience—all in one summer.And to my surprise, I found that country life has a lot to offer that city life doesn't—no pollution or traffic jams, for instance!My experience made me want to work where I'm needed and appreciated.I don't miss the city at all!【生词摘录】1.live: adj.not dead or artificial;living

case.In the early days of radio, stations were capable of broadcasting only a narrow range of sounds, which was all right for the human voice but music didn't sound very good.There was also a great deal of crackling and other static noises that further interfered with the quality of the sound.A man named Edwin Armstrong, who was a music lover, set out to change this.He invented FM radio, a technology that allowed stations to send a broad range of frequencies that greatly improved the quality of the music.Now, you'd think that this would have made him a millionaire;it didn't.Radio stations at that time had invested enormous amounts of money in the old technology.So the last thing they wanted was to invest millions more in the new technology.Nor did they want to have to compete with other radio stations that had a superior sound and could put them out of business.So they pressured the Federal Communications Commission, the department of the United States government that regulates radio stations, to put restrictive regulations on FM radio.The result was that its use was limited to a very small area around New England.Of course as we all know, Edwin Armstrong's FM technology eventually prevailed and was adopted by thousandsof stations around the world.But this took years of court battles and he never saw how it came to affect the lives of almost everyone.【生词摘录】1.crackling: n.[C]爆裂声2.static: adj.静电的3.FM: 调频(frequency modulation)4.frequency: n.[C]频率lionaire: n.[C]百万富翁，大富豪6.restrictive: adj.限制性的7.regulation: n.规则，规章8.prevail:

a special train was established to take people from New York to an exposition in Chicago.It was so successful that regular service was then set up between these cities.The inaugural trip of the Twentieth Century Limited was made in 1902.The train was different from what anyone had ever seen before.It was pulled by a steam engine and had five cars: two sleepers, a dining car, an observation car, and a baggage car, which, believe it or not, contained a library.The 42 passengers the train could carry were waited on by a large staff.There were even secretaries and a barber on board.It wasn't long before people had to wait two years to get a reservation.As time passed, technical improvements shortened the trip by a few hours.Perhaps the biggest technological change occurred in 1945, the switch from steam to diesel engines.By the 1960's, people were traveling by car and airplane.Unfortunately, the great old train didn't survive until the end of the century it was named

Scientists are always on the lookout for alternative sources of energy. Today we're going to discuss one that's so plentiful they say it could supply more energy than all the coal and oil in the world. It's found in something called gas hydrate and, believe it or not, that's a kind of ice. That's right. But the water in this ice was way down below the Earth's surface when it was frozen, so it was under a lot of pressure. And trapped inside the crystals of ice are individual molecules of methane—that's what's in natural gas. All this makes gas hydrate pretty strange stuff. If you touch a match to a piece of this ice, it'll burst into flame. And when geologists bring a chunk of it up to the surface to study at normal air pressure and temperature, gas hydrate begins to hiss and bubble, and in less than half an hour, the ice melts and the methane inside escapes into the air. Now, as you might guess, this can make gas hydrate kind of hard for miners to handle. And then there's the problem of where it's located in frozen arctic regions or in ocean waters off the Atlantic coast, and up to a mile down. Environmentalists warn that mining it could even be disastrous. Offshore drilling could allow seawater to seep down into the huge icy deposits and release tons of methane up into the atmosphere. And methane, our listeners may recall, is a greenhouse gas that could really worsen the problem of global warming. So, gas hydrate may offer some interesting possibilities. But, with all these drawbacks, I'm not going to hold my breath waiting for it to fuel my furnace.

Today, I want to talk about the Cariboo gold rush of 1858, which began when gold was discovered in the frontier town of Quesnel Forks in the Canadian province of British Columbia. By 1861 thousands of men had flocked to the region hoping to strike it rich. Naturally, as the town grew, supplies had to be brought in, and this was done with mules. Now the mules were quite reliable, but there were some drawbacks. For example, a mule carrying a heavy load could travel only 15 miles in a day, meaning that a typical trip into Quesnel could take as long as 20 days. So, as the demand for supplies continued to grow, a group of merchants and packers decided to try a new approach, believe it or not, they shipped in a herd of camels. I know that sounds strange, but camel trains had been used quite effectively during the California gold rush some 10 years earlier. But the results in the Cariboo region weren't quite the same. In fact it was a disaster. The camels couldn't carry the heavier loads the merchants expected them to. Their two-toed feet were perfect for desert travel, but they weren't suited for Cariboo's rugged mountain terrain. To make matters worse, the mules became very agitated whenever they came across a camel and that caused a lot of accidents on the treacherous mountain trails. The mulepackers went so far as to threaten the camel owners with a lawsuit. But the reason the merchants finally got rid of the camels is because these animals simply weren't cut out for the job.
