In the lecture, the professor made several points about whether dinosaurs are endotherms as humans. The professor argues that the dinosaurs are not believed as endotherms by many scientists. However, the passage claims that dinosaurs are considerably endotherms which supported by several evidences.Firstly, the professor points out that polar dinosaurs could live in such cold climate for the reason that the environment of the polar area was much warmer than today. Also, the professor indicates that dinosaurs had adapted to cold climates by hibernating like most animals do today. That differs from passages that states that the ability to live in such cold environment of polar dinosaur provide strong evidence to that dinosaurs were endotherms. The professor in the lecture cast doubt on such evidence.Also, on the contrary of the content of passage that the leg position of dinosaurs strongly suggests that only the this under the body leg position allows the animals to running efficiently which most occur in the body of endotherms , the professor illustrates that this leg position does not necessarily lend support to the conclusion of the passage. The professor provides reason for this leg position that could support this huge weight of dinosaurs and enable them to grow large and they did not need legs under body to move fast. Therefore, the professor refutes the evidence from the passage about leg position.In addition, the professor claims that dinosaurs did have this bone structure haversian canal and they also have the structure called gross ring to keep them stop grow when the climate was freezing. Nevertheless, the passage argues that this bone structure proves that the dinosaurs were endotherms, which is totally jeopardized by the professor.Therefore, according to this professor, the conclusion of the passage is totally not accurate and authentic. The evidences make no sense to prove this idea.。

希望大家能够按照以下的备考思路，更好地攻克托福写作题目。
第一部分：阅读文本解析The mystery of whether humans are alone in the universe may have been answered by a 1.9-kilogram meteorite discovered in Antarctica in 1984. After careful analysis, scientists from NASA announced that the meteorite, which they say came from Mars, once contained organic matter that was extraterrestrial in origin.While the meteorite was found in 1984, it was not until 2009 that NASA scientists claimed that it possessed strong evidence that life existed on Mars billions of years in the past. The reason for the delay is that recent advances in electron microscopy made it possible for scientists to see various features on the meteorite that had previously been overlooked. What they found with a high-powered electron microscope was evidence of extremely tiny fossils of bacteria-like organisms on the meteorite. This was a clear indicator that Mars once held life at least on the microscopic level.Scientists believe the meteorite formed on Mars around 3.6 to 4 billion years ago. Then, Mars was much warmer and wetter than it is today. Water likely entered fractures in the rock. Then, living organisms soon followed and made their homes inside these fissures. Scientists defend their theory by citing the carbonate minerals found in the rock. These minerals, they speculate, could only have been formed by living organisms.Further proof of the existence of life is that the meteorite contains magnetite. Studies have determined that roughly onequarter of the magnetite in the meteorite is in the guise of small crystals. These crystals are chemically pure and structurally perfect, and they have unique three-dimensional shapes that could only have been formed by living organisms, not by organic matter. Taken altogether, these scientists are convinced they have proof that life exists—or at least existed—elsewhere in the universe.阅读要点：观点：The meteorite, which they say came from Mars, once contained organic matter that was extraterrestrial in origin.根据从火星掉落的陨石表明，火星上有生物存在。

托福TPO4口语Task3阅读文本： Evening Computer Classes May Be Added The computer department is considering offering evening classes in the fall. The proposal to add the classes is a response to student complaints that day time computer classes have become increasingly over crowded and there are no longer enough computers available. The department has decided that despite some added expense, the most cost-effective way of addressing this problem is by adding computer classes in the evening. It is hoped that this change will decrease the number of students enrolled in day classes and thus guarantee individual access to computers for all students in computer classes. 托福TPO4口语Task3听力文本： Now listen to two students discussing the article. (man) I just don’t think this will work. (woman) Why not? (man) Because it’s not gonna solve the problem. Students are busy at night, I mean, we have jobs, families, clubs, social events. Most of us already have something to do every single night of the week. (woman) I see your point. I sure couldn’t fit anything into my schedule during the week. I’ve got swimming practice most nights. (man) Right! And as far as expense goes, I think they’re going about it the wrong way. I mean, it cost money to hire more teachers and keep the academic building open later, which is a lot more expensive than simply just buying more computers. (woman) More computers? (man) That’s right! Computer prices have come way down the past few years. So the department won’t have to spend as much now as they did in the past. Besides, the computer department classrooms, you know, the rooms themselves, they are actually very big, there’s plenty of space to add more computers. 托福TPO4口语Task3题目： The computer department is considering a scheduling change. Explain the man’s opinion of the change and the reasons he gives for holding that opinion. 托福TPO4口语Task3满分范文： The school is planning to start offering evening computer classes due to it’s popularity and it will be cost effective. In the conversation the man disagrees with the school’s plan for the following reasons. First of all, many students are busy at night doing other activities. For example, they might have jobs, families, clubs and social events to attend to. He also thinks that the school should buy more computers to meet the needs instead of opening up more classes. Computer prices decreased a lot during the years, they have become very cheap. Hiring more teaching staff is going to be more expensive for the school in the long run, plus there will be enough space for the new equipment. 以上是给大家整理的托福TPO4口语Task3阅读文本+听力文本+题目+满分范文，希望对你有所帮助!。

The Impact of Technology on Work。
In the past few decades, technology has had a significant impact on the way we work. From the automation of repetitive tasks to the rise of remote work, technology has changed the way we approach our jobs and careers. In this essay, we will explore the impact of technology on work and how it has shaped the modern workplace.One of the most significant impacts of technology on work has been the automation of tasks. With the advent of computers and software, many repetitive and mundane tasks can now be completed by machines. This has led to increased efficiency and productivity in the workplace, as employees are able to focus on more complex and creative tasks. However, it has also led to concerns about job displacement and the future of work, as many traditional jobs are beingreplaced by machines.Another major impact of technology on work has been the rise of remote work. With the development of communication and collaboration tools, employees are now able to work from anywhere in the world. This has led to greater flexibility and work-life balance for many workers, as well as the ability to tap into a global talent pool. However,it has also raised concerns about the isolation and disconnection of remote workers, as well as the security risks associated with remote work.Furthermore, technology has also changed the way we communicate and collaborate in the workplace. With the rise of email, instant messaging, and video conferencing, employees are now able to communicate and collaborate in real-time, regardless of their location. This has led to greater efficiency and faster decision-making, but it has also raised concerns about information overload and the blurring of work-life boundaries.In addition, technology has also had a significantimpact on the skills and abilities required in the modern workplace. With the rise of artificial intelligence and machine learning, employees are now required to have a greater understanding of technology and data analysis. This has led to a growing demand for workers with technical skills, as well as the need for continuous learning and upskilling.In conclusion, technology has had a profound impact on the way we work. From the automation of tasks to the rise of remote work, technology has changed the way we approach our jobs and careers. While it has led to increased efficiency and productivity, it has also raised concerns about job displacement and the future of work. As technology continues to evolve, it will be important for employers and employees to adapt and embrace the changes in order to thrive in the modern workplace.。
综合英语4unit3书上作文
综合英语4unit3书上作文Comprehensive English 4 Unit 3 EssayLearning a new language can be a challenging yet rewarding experience for individuals of all ages and backgrounds. The process of acquiring a second language not only broadens one's communication abilities but also opens the door to a deeper understanding of diverse cultures and perspectives. In the case of the Comprehensive English 4 textbook, the third unit focuses on various aspects of language learning, providing a comprehensive framework for students to enhance their English proficiency.One of the key components explored in this unit is the role of motivation in language acquisition. Motivation is a crucial factor that can significantly impact an individual's willingness to engage in the learning process and persist through the challenges that often arise. The textbook delves into the distinction between intrinsic and extrinsic motivation, highlighting how internal drives such as personal interest and a desire for self-improvement can be more sustainable than external rewards or pressures.By understanding the importance of intrinsic motivation, students can develop a deeper appreciation for the learning experience itself, rather than solely focusing on the end goal of language proficiency. This shift in mindset can lead to a more enjoyable and fulfilling journey, as learners are able to find joy in the process of acquiring new vocabulary, mastering grammatical structures, and improving their communication skills.Moreover, the unit emphasizes the significance of language learning strategies, which are the specific techniques and approaches that individuals employ to enhance their language acquisition. From memory-based strategies like mnemonic devices to cognitive strategies such as inference and deduction, the textbook provides a comprehensive overview of the various tools available to language learners.By exploring these strategies, students are empowered to take a more active and informed role in their learning process. They can experiment with different techniques, identify the ones that work best for their individual learning styles, and adapt their approach as they progress through their language-learning journey.Another crucial aspect addressed in the unit is the role of feedback and error correction in language learning. The textbookacknowledges that making mistakes is a natural and inevitable part of the learning process, and it encourages students to view errors as opportunities for growth and improvement, rather than sources of shame or discouragement.By emphasizing the constructive nature of feedback, the unit helps students develop a growth mindset, where they are willing to take risks, experiment with new language structures, and actively seek out guidance from their instructors and peers. This approach fosters a supportive and collaborative learning environment, where students feel empowered to push the boundaries of their linguistic abilities without fear of criticism or judgment.Furthermore, the unit delves into the concept of language anxiety, which can be a significant barrier to effective language learning. Feelings of self-consciousness, fear of making mistakes, and apprehension about communicating in a non-native language can all contribute to language anxiety and hinder a student's progress.The textbook provides strategies for managing and overcoming language anxiety, such as practicing relaxation techniques, building confidence through incremental successes, and cultivating a positive and supportive learning community. By addressing this important aspect of language learning, the unit helps students develop the emotional resilience and self-awareness necessary to navigate thechallenges they may encounter along the way.In addition to these core themes, the Comprehensive English 4 textbook also explores the role of cultural awareness and sensitivity in language learning. It recognizes that language is not simply a set of grammatical rules and vocabulary but rather a reflection of the cultural norms, values, and traditions of the people who use it.By delving into cultural aspects such as etiquette, customs, and communication styles, the unit encourages students to approach language learning with a deeper understanding and appreciation for the diverse perspectives and worldviews that shape the target language. This cultural awareness not only enhances the students' language skills but also fosters empathy, respect, and a more nuanced understanding of the global community.Throughout the unit, the textbook also emphasizes the importance of ongoing practice and exposure to the target language. It acknowledges that language learning is a lifelong journey, and that consistent engagement with the language, through activities such as reading, listening, speaking, and writing, is essential for maintaining and improving proficiency over time.By reinforcing the need for regular practice and exposure, the unit helps students develop a sustainable and long-term approach tolanguage learning, rather than treating it as a short-term goal or a one-time accomplishment. This mindset shift can lead to a deeper appreciation for the language and a greater commitment to continuous growth and development.In conclusion, the Comprehensive English 4 textbook's third unit provides a comprehensive and insightful exploration of the various aspects of language learning. From the role of motivation and learning strategies to the importance of feedback, cultural awareness, and ongoing practice, the unit equips students with the knowledge and tools necessary to navigate the challenges and embrace the rewards of acquiring a new language.By fostering a growth mindset, encouraging self-reflection and experimentation, and emphasizing the holistic nature of language learning, the textbook empowers students to take an active and empowered role in their language-learning journey. As they progress through the unit and apply the principles and strategies presented, students can develop a deeper understanding of the language, a greater appreciation for cultural diversity, and the confidence to communicate effectively in English across a wide range of contexts.。

如何使用这个文件呢？TPO4 综合写作听力+阅读原文ReadingEndotherms are animals such as modern birds and mammals that keep their body temperatures constant. For instance, humans are endotherms and maintain an internal temperature of 37°C, no matter whether the environment is warm or cold. Because dinosaurs were reptiles, and modern reptiles are not endotherms, it was long assumed that dinosaurs were not endotherms. However, dinosaurs differ in many ways from modem reptiles, and there is now considerable evidence that dinosaurs were, in fact, endotherms.Polar dinosaursOne reason for believing that dinosaurs were endotherms is that dinosaur fossils have been discovered in Polar Regions. Only animals that can maintain a temperature wellabove that of the surrounding environment could be active in such cold climates.Leg position and movementThere is a connection between endothermy and the position and movement of the legs. The physiology of endothermy allows sustained physical activity, such as running. But running is efficient only if an animal's legs are positioned underneath its body, not at the body's side, as they are for crocodiles and many lizards. The legs of all modern endotherms are underneath the body, and so were the legs of dinosaurs. This strongly suggests that dinosaurs were endotherms.Haversian canalsThere is also a connection between endothermy and bone structure. The bones of endotherms usually include structures called Haversian canals. These canals house nerves and blood vessels that allow the living animal to grow quickly, and rapid body growth is in fact a characteristic of endothermy. The presence of Haversian canals in bone is a strong indicator that the animal is an endotherm, and fossilized bones of dinosaurs are usually dense with Haversian canals.ListeningProfessor: Many scientists have problems with the arguments you read in the passage. They don't think those arguments prove that dinosaurs were endotherms.Take the polar dinosaur argument. When dinosaurs lived, even the polar regions, where dinosaur fossils have been found, were much warmer than today, warm enough during part of the year for animals that were not endotherms to live. And during the months when the polar regions were cold, the so-called polar dinosaurs could have migrated to warmer areas or hibernated like many modern reptiles do. So the presence of dinosaur fossils in polar regions doesn't prove the dinosaurs were endotherms.Well, what about the fact that dinosaurs have their legs placed under their bodies, not out to the side like crocodiles. That doesn't necessarily mean dinosaurs werehigh-energy endotherms built for running. There is another explanation for having legs under the body. This body structure supports more weight, so with the legs under their bodies, dinosaurs can grow to a very large size. Being large had advantages for dinosaurs, so we don't need the idea of endothermy and running to explain why dinosaurs evolved to have their legs under their bodies.Ok, so how about bone structure? Many dinosaur bones do have Haversian canals, that's true. The dinosaur bones also have growth rings. Growth rings are thickening of the bone that indicates periods of time when the dinosaurs weren't rapidly growing. These growth rings are evidence that dinosaurs stopped growing or grew more slowly during cooler periods. This pattern of periodic growth, you know, rapid growth followed by no growth or slow growth, and then rapid growth again, is characteristic of animals that are not endotherms. Animals that maintain a constant body temperature year-round as true endotherms do grow rapidly even when the environment becomes cool.TPO4综合写作范文推荐Sample ResponseThe professor actually contradicts the statements made in the passage. She is of the view that dinosaurs are not endotherms i.e. they were not able to keep their body temperature at a constant rate.The professor contradicts the issue of dinosaurs being endothers based on the availability of fossils being available in the polar regions, she say that the polar regions in those days were not as cold as they are today i.e. at least warm enough for dinosaurs to live. During harsh winters she says that there is a possibility of the dinosaurs actually migrating to warmer regions.The issue of leg position and movement being used as a reason to classify the dinosaurs as endotherms does not please the professor either. She says that dinosaurs had legs under their bodies to support their huge bodies i.e. the legs under the body of the dinosaur were actually to support the huge weight of the dinosaur and not to provide it with a body structure like endotherms (which is actually suited for running).The professor acknowledges the presence of haversian canals but also points out that that the fossils show the presence of growth rings. These rings occur due to the thickening of the bone.The thickening indicates that the dinosaurs weren’t actually growing continuous ly but were experiencing periods of rapid growth and periods of no growth in succession. This pattern, she says is characteristic of non endothermic animals. Thus it can be inferred that the professor challenges the passage by giving reasons as to why she thinks that the dinosaur is not an endotherm.首先，就是在自己做托福TPO模考之后，可以根据这里面的听力的文本，来检验自己的听力内容是否抓的足够好，尤其是要看写的够不够全！很多时候，我们的综合作文之所以分低，就是因为听力写的不全！第二点，也可以用于在托福考试前来做跟读，有不少托福考生跟小托君说，自己的口语实力不够，那么做跟读，仔细地来模仿ETS官方素材，是一个很好的提高自己口语的方式。

托福TPO4阅读真题原文Part3Petroleum ResourcesPetroleum, consisting of crude oil and natural gas, seems to originate from organic matter in marine sediment. Microscopic organisms settle to the seafloor and accumulate in marine mud. The organic matter may partially decompose, using up the dissolved oxygen in the sediment. As soon as the oxygen is gone, decay stops and the remaining organic matter is preserved.Continued sedimentation-the process of deposits settling on the sea bottom-buries the organic matter and subjects it to higher temperatures and pressures, which convert the organic matter to oil and gas. As muddy sediments are pressed together, the gas and small droplets of oil may be squeezed out of the mud and may move into sandy layers nearby. Over long periods of time (millions of years), accumulations of gas and oil can collect in the sandy layers. Both oil and gas are less dense than water, so they generally tend to rise upward through water-saturated rock and sediment.Oil pools are valuable underground accumulations of oil, and oil fields are regions underlain by one or more oil pools. When an oil pool or field has been discovered, wells are drilled into the ground. Permanent towers, called derricks, used to be built to handle the long sections ofdrilling pipe. Now portable drilling machines are set up and are then dismantled and removed. When the well reaches a pool, oil usually rises up the well because of its density difference with water beneath it or because of the pressure of expanding gas trapped above it. Although this rise of oil is almost always carefully controlled today, spouts of oil, or gushers, were common in the past. Gas pressure gradually dies out, and oil is pumped from the well. Water or steam may be pumped down adjacent wells to help push the oil out. At a refinery, the crude oil from underground is separated into natural gas, gasoline, kerosene, and various oils. Petrochemicals such as dyes, fertilizer, and plastic are also manufactured from the petroleum.As oil becomes increasingly difficult to find, the search for it is extended into more-hostile environments. The development of the oil field on the North Slope of Alaska and the construction of the Alaska pipeline are examples of the great expense and difficulty involved in new oil discoveries. Offshore drilling platforms extend the search for oil to the oceans continental shelves-those gently sloping submarine regions at the edges of the continents. More than one-quarter of the worlds oil and almost one-fifth of the worlds natural gas come from offshore, even though offshore drilling is six to seven times more expensive than drilling on land. A significant part of this oil and gas comes from under the North Sea between Great Britain and Norway.Of course, there is far more oil underground than can be recovered. It may be in a pool too small or too far from a potential market to justify the expense of drilling. Some oil lies under regions where drilling is forbidden, such as national parks or other public lands. Even given the best extraction techniques, only about 30 to 40 percent of the oil in a given pool can be brought to the surface. The rest is far too difficult to extract and has to remain underground.Moreover, getting petroleum out of the ground and from under the sea and to the consumer can create environmental problems anywhere along the line. Pipelines carrying oil can be broken by faults or landslides, causing serious oil spills. Spillage from huge oil-carrying cargo ships, called tankers, involved in collisions or accidental groundings (such as the one off Alaska in 1989) can create oil slicks at sea. Offshore platforms may also lose oil, creating oil slicks that drift ashore and foul the beaches, harming the environment. Sometimes, the ground at an oil field may subside as oil is removed. The Wilmington field near Long Beach, California, has subsided nine meters in 50 years; protective barriers have had to be built to prevent seawater from flooding the area. Finally, the refining and burning of petroleum and its products can cause air pollution. Advancing technology and strict laws, however, are helping control some of these adverse environmental effects.Paragraph 1: Petroleum, consisting of crude oil and natural gas, seems to originate from organic matter in marine sediment.

TPO-4TPO 04 – Listening PartConversationNarratorListen to a conversation between a student and a librarian.LibrarianCan I help you?StudentYeah, Ineed to find a review. It’s for myEnglish class. Wehave to find reviews of theplay we are reading. But theyhave to be from when the play was first performed,so I need to know when that was and I suppose I should startwith newspaper reviews and…LibrarianContemporary reviews.StudentSorry?LibrarianYou want contemporaryreviews. What’s the name of the play?StudentIt’s Happy Strangers. Itwas written in 1962 and we are supposed to writeabou t itsinfluence on American theatre and show why it’s been so important.LibrarianWell, that certainly explains whyyour professor wantsyou to read some ofthose old reviews. The critiquesreally torethe play to pieceswhen it opened.It’s so controve rsial. Nobody had everseen anything like it on the stage.StudentReally? Isthat a big deal?LibrarianOh, sure. Ofcourse thecritiques’reaction made some people kind ofcuriousabout it.Theywanted to see what’s causing all the fuss. In fact,we wer eonvacation in New York. Oh, I had tobe, eh,around 16 or so, and myparentstookme to see it. That would’ve been about 1965.StudentSo that wasthe year premier,great, but eh,newspaper from back then weren’tonline,so, how do I…LibrarianWell, wehave copies ofall the newspapers in the basement, and all the majorpapers publish reference guides to their articlesreviews,etc. You willfindthem in the reference stacksin the back. ButI start with 1964, so I thinktheplay had been running for a little while when I saw it.StudentHow do you like it?I mean just two characterson the stage hanging aroundand basically doing nothing.LibrarianWell, Iwas impressed. Theactors werefamous, and besides it was myfirsttime in a realtheatre.But you are right.It was definitelydifferent from manyplays that we read in high school. Ofcourse, in a small town the assignmentsare prettytraditional.StudentYeah, I’ve only read it but it doesn’t seem like it would be much fun to watch.The st orydoesn’t progress in anysort oflogical matter,doesn’t have realending either,just stops. Honestly,you know,I thought it was kind of slow andboring.LibrarianOh, wellI guess you might think that. Butwhen Isaw it back then it wasanything but boring. Some parts werereally funny,but Iremembercrying too.But I’m not sure just reading it. You know, they’ve done thisplay at least onceon campus. I’m sure thereis a tape of theplay in our video library. You mightwant to borrow it.StudentThat’s a good idea. I’ll have a better idea of what I really thinkof it before I read those reviews.LibrarianI’m sure you willbe surprised that anyone ever found it radical. But you will see whyit is still powerful, dramatically speaking.StudentYeah, it must be something about it,or the professor wouldn’thave assigned it.I’m sure I’ll figure it out.LectureNarratorListen to part ofa lecturein a biology class. The class is discussing animal behavior.ProfessorOk, the nextkind ofanimal behavior I want to talkabout might be familiar toyou. You mayhave seen, for example, a bird that’s in the middle ofa mating ritual, and suddenly it stops and preens,you know, takesa few momentstostraighten its feathers, and then returns tothe mating ritual. This kind of behavior,this doing something that seems completelyout ofplace, is what wecalla ‘Displacement Activity’. Displacement activitiesare activities that animal’s engaging in when theyhave conflicting drives. Ifwe takeour examplefrom a minute ago, if thebird is afraid ofits mate,it’s conflicted.It wantsto mate but it’s also afraid and wantsto run away. So, instead, it startsgrooming itself.So, the displacement activity,the grooming, the straightening ofits feathers,seems to be an irrelevant behavior.So, what do you think anotherexample ofa displacementactivity might be?KarlHow about an animal that, um, instead of fighting its enemyor running away,itattacksa plant or a bush?ProfessorThat’s reallygood suggestion, Karl. But that’s called ‘redirecting’.The animal isredirecting itsbehavior to another object, in this case, theplant or the bush.But that’s not an irrelevant or inappropriate behavior.The behavior makessense. It’s appropriate under the circumstances.But what doesn’t make senseis the object thebehavior‘s directed towards. Ok, who else? Carol?CarolI thinkI read in another class about an experimentwhere an object that theanimal was afraid of was put nextto its food – nextto the animal’s food. Andthe animal, it wasconflicted between confronting theobject and eating thefood, so instead, it just fellasleep. Like that?ProfessorThat’s exactlywhat I mean. Displacement occursbecause theanimal’s got twoconflicting drives – two competing urges, in thiscase, fear and hunger. Andwhat happens is, theyinhibit each other,theycanceleach other out in a wayand a third seemingly irrelevant behavior surfaces through a processthat wecall‘Disinhibition’. Now in disinhibition, thebasic idea is that two drivesthatseem to inhibit,to hold back, a third drive. Or, well,they’re getting in a wayofeach in a… in a conflict situation and somehow lose control,lose theirinhibiting effecton that third behavior,which means thatthe third drive surfaces, it’s expressed in theanimal’s behavior.Now,these displacementactivities can include feeding, drinking, grooming, even sleeping. These arewhat we call ‘Comfort Behavior’.So whydo you thinkdisplacement activitiesare so often comfort behaviors, such as grooming?KarlMaybe because it’s easy for them to do? I mean,grooming is like one of themost accessible things an animal can do. It’s something theydo all thetime,and theyhave the stimulus right there on the outside oftheir bodies in order to do thegrooming, or if food is right in front of them.Basically, theydon’t have to think verymuch about those behaviors.CarolProfessor,isn’t it possible that animals groom because they’ve got messed upa little from fight ing or mating? I mean if a bird’s feathersget ruffled or an animal’s fur,maybe it’s not so strange for them to stop and tidythemselves upat that point.ProfessorThat’s another possible reason although it doesn’t necessarily explain other behavi ors such as eating, drinking or sleeping. What’s interesting is that studies have been done that suggest thatthe animal’s environment mayplay apart in determining what kind of behavior it displays. For example,there’s abird, the ‘wood thrush’,anyway, when the ‘wood thrush’is in an attack-escapeconflict, that is, it’s caught between the two urges to escape from or to attackan enemy,if it’s sitting on a horizontalbranch, it’ll wipe itsbeak on itsperch.Ifit’s sitting on a verticalbranch, it’ll groom its breast feathers.The immediateenvironment of thebird, its immediate,um, its relationship to its immediateenvironment seemsto play a part in which behavior will display.LectureNarratorListen to part ofa lecturein a literatureclass.ProfessorAll right,so let me close today’s class with some thoughts to keep in mindwhile you are doing tonight’s assignment. You will be reading one of RalphWaldo Emerson’s best-known essays ‘Self-Reliance’and comparing it with hispoems and other works. Ithink this essay has the potentialto be quitemeaningful for all ofyou as young people who probably wonder about thingslike truth and whereyour lives are going - all sorts ofprofound questions.Knowing something about Emerson’s philosophie s will help you when youread ‘Self-Reliance’.And basically, one ofthe main beliefs that he had wasabout truth. Not that it’s something that wecan be taught,Emerson says it’sfound within ourselves. So this truth,the idea that it’s in each one ofus, is oneof thefirst points that you’ll see Emerson ** in this essay. It’s a bitabstract but he’s very into…ah…into each person believing his or her ownthought, believing in yourself, the thought or conviction that’s truefor you. But actually, he tiesthat in with a sort of ‘universal truth’ – something that everyone knows but doesn’t realizetheyknow. Most of us aren’tin touch with ourselvesin a way,so we just aren’t capable of recognizing profound truth. Ittakesgeniuses, people like, say,Sh akespeare, who’reunique because when theyhave a glimpse at this truth,this universal truth,theypay attention to it and expressit and don’t just dismiss it like most people do.So Emerson is reallyinto each individual believing in and trusting him orherself.You’ll see thathe writesabout, well,first, conformity. Hecriticizes that people of his time for abandoning their own minds and their own wills for thesake of conformity and consistency. Theytryto fit in with the restof the worldeven thou gh it’s at odds with their beliefsand their identities. Therefore,it’sbest to be a non-conformist – to do your own thing, not worrying about whatother people think. That’s an important point. Hereally drives thisargumenthome throughout the essay.When you are reading, I want you to think about that and why thatkind ofthought would be relevant to the readers of his time. Rememberthis is 1838,‘Self-Reliance’was a novel idea at thetime and the United State’s citizenswereless secure about themselvesas individuals and as Americans. Thecountry as a whole was trying to define itself. Emerson wanted to give peoplesomething to reallythink about, help them find theirown wayand what it meantto be who theywere.So that’s something that I thin k is definitely as relevanttoday as it was then, probably, um, especially among young adults likeyourselves, you know,uh, college being a time to sort of reallythink about whoyou are and where you’re going.Now we already said that Emerson really emphasizesnon-conformity, right,asa way to sort of not lose your own self and identityin the world, to have yourown truth and not be afraid to listen to it. Well, he takes thisa stepfurther. Notconforming also means, uh, not conforming with yourself or your past. Whatdoes that mean?Well, if you’ve always been a certain way or done a certainthing, but it’s not working for you anymore,or you’re not content,Emersonsays that it’d be foolish to be consistent evenwith our own past. ‘Focus on t hefuture,’ he says, “That'swhat matters more.Inconsistency is good.”He talksabout a ship’s voyage and this is one of themost famous bits oftheessay - how the best voyage is made up of zigzag lines. Up close, it seemsalittle all over theplace, but from fartheraway, the truepath shows and in theend it justifies all theturns along the way.So, don’t worry if you are not surewhere you’re headed or what your long-term goals are.Staytrue to yourselfand it’ll make sense in the end. I mean,I can at test tothat. BeforeI was aliteratureprofessor, Iwas an accountant.Beforethat,I was a newspaperreporter.My life is taking some prettyinteresting turns and here I am, veryhappy with my experiencesand wherethey’ve brought me. Ifyou relyonyourself and trust your own talents,your own interest, don’t worry,your pathwill make sense in the end.ConversationNarratorListen to a conversation between a student and a professor.ProfessorHey,Jane, you look like you arein a hurry.StudentYeah, things are a little crazy.ProfessorOh yeah? What’s going on?StudentOh, it’s nothing. Well, since it’s your class, I guess it’s OK. It’s, it’s just I am having trouble with mygroup project.ProfessorAh, yes, due next week.What’s your group doing again?StudentIt’s about United StatesSupreme Court Decisions. We are looking at theimpact of recent caseson propertyrights, municipal land use cases, owningdisputes.ProfessorRight,OK. And i t’s not going well?StudentNot really.I’m worried about othertwo people in my group. Theyare just sittingback, not really doing their fair share ofthe work and waiting for an A. It’s kindof stressing me out,because we aregetting close to thedeadline and I feellikeI’m doing everything for this project.ProfessorAh, the good old free writerproblem.StudentFree writer?ProfessorAh, it’s just a term that describes thissituation, when people in the group seekto getthe benefits ofbeing in a group without contributing tothe work. Anyway,what exactly do you mean when you say theyjust sit back? I mean,they’vebeen following theweekly progress repotswith me.StudentYes, but I feellike I’m doing 90% ofthe work. I hateto sound so n egative here,but honestly, theyare taking credit for things theyshouldn’t take credit for. Likelast weekin the library,we decided to split up theresearch into 3 partsandeach of us was supposed to find sources in the library for our parts. I went offto the stackand found some really good materialfor mypart, but when I gotback to our table,theywere just goofing off and talking. So I wentand gotmaterialsfor theirsections as well.ProfessorUm…you know you shouldn’t do that.StudentI know,but I didn’t want to risk the project going down thedrain.ProfessorI know Teresa and Kevin. I had both ofthem on othercourses. So, I’m familiarwith the workand work habits.StudentI know,me too. That’s why this has reallysurprised me.ProfessorDo you…does your group like your topic?StudentWell, Ithink we’d all ratherfocus on casesthat deal with personal liberties,questions about freedom of speech,things like that.But Ichose propertyrights.ProfessorYou chose the topic?StudentYeah, Ithought it would be good for us, all of us to trysomething new.ProfessorUm…maybe that’s part of theproblem. Maybe Teresa and Kevin aren’t thatexcited about the topic? And since you picked it,have you thought…talktothem at all about picking a different topic?StudentBut we’ve got all the sourcesand it’s due next week. We don’t have time to start from scratch.ProfessorOK, I will letyou go ‘cause I know you are so busy. But you might consider talking to your group about your topic choice.StudentI willthink about it. Gotto run, see you in class.LectureNarratorListen to part ofa lecturein a geology class.ProfessorNow we’ve got a few minutes beforewe leave for today.So I’ll just touch on an inter esting subject that I think makesan important point. We’ve been covering rocks and different types ofrocks for the last severalweeks. Butnext weekwe are going to do something a bit different.And to get started I thought I’d mention something that sho ws how uh…as a geologist, you need toknowabout more than just rocksand the structureof solid matter,moving rocks, you may have heard about them.It’s quite a mystery.Death valley is this desert plane, a dry lake bed inCalifornia surrounded bymountains and on the desertfloor these huge rocks,some ofthem hundreds of pounds. And theymove. Theyleave long trailsbehind them,tracksyou might say as theymove from one point to another.Butnobody has been able to figure out how theyare moving because no one haseverseen it happen.Now there area lot of theories,but all we know for sure is that people aren’t’moving the rocks. Thereare no footprints, no tyretracks and no heavymachinery like a bulldozer…uh, nothing was everbrought in to move theseheavy rocks.So what’s going on? TheoryNO.1 ---Wind? Some researchersthink powerfuluh…windstorms might move the rocks. Most of therocks move in the samedirection as the dominant wind pattern from southwest to northeast.But some,and thisis interesting, move straight west while some zigzag or even move inlarge circles.Um…How can that be?How about wind combined with rain? The ground ofthis desertis made of clay. It’s a desert,so it’s dry.But when thereis theoccasionalrain, the clay gr ound becomesextremelyslippery.It’s hard foranyone tostand on, walk on. Some scientiststheorized that perhaps when theground is slipperythe high winds can then move the rocks. There’s a problemwith this theory.One team ofscientists flooded an area ofthe desert with water,then tryto establish how much wind forcewould be necessary to move therocks. And guess this, you need winds of at least five hundred miles an hour to move just the smallest rocks. And winds that strong have neverbeen recorded. Ever!Not on thisplanet.So Ithink it’s safe to say that that issues has been settled.Hereis another possibility–ice.It’s possible that rain on thedesert floor could turn to thin sheetsof ice when temperaturesdrop at night. So if rocks…uh becomi ngbetter than ice,uh … OK, could a pieceof ice with rocks in it be pushed around by thewind? Butthere’s a problem with thistheory,too. Rockstrapped in ice togetherwould have moved togetherwhen the ice moved. Butthat doesn’talways happen. The rocksseem to take separate routes.Thereare a fewother theories. Maybe the ground vibrates, or maybe theground itself is shifting, tilting. Maybe the rocksare moved bya magnetic force. But sadly all these ideas have been eliminated as possibilities. The re’s just no evidence.I bet you are saying to yourself well, whydon’t scientists just setup video camerasto record what actually happens? Thing is this is a protective wilderness area. So by law that type of research isn’t allowed. Besides, in powerful windstorms, sensitive camera equipment would be destroyed. Sowhycan’t researchers just live therefor a while until theyobserve the rocks’moving? Same reason.So whereare we now? Well, right now we still don’t have any answers. So allthis leads backto mymain point – you need to know about more than justrocks as geologists. The researchersstudying moving rocks, well, theycombine their knowledge of rockswith knowledge of wind, ice and such…umnot successfully, not yet.But you know,theywould even have been able to getstartedwithout uh… earth science understanding – knowledge about wind,storms, you know,meteorology. You need tounderstand physics. So forseveralweeks like Isaid we’ll be addressing geology from a wider prospective.I guess that’s all for today. See you next time.LectureNarratorListen to part ofa lecturein a United Statesgovernment class.ProfessorOK, last timewe were talking about government support for the arts. Who cansum up some of themain points? Frank?FrankWell, Iguess there wasn’t reallyany, you know, official government support forthe artsuntil thetwentieth century. Butthe first attempt theUnited Statesgovernment made to,you know, to support the artswas the FederalArtProject.ProfessorRight,so what can you say about the project?FrankUm…it was started during the Depression, um…in the 1930s to employout-of-work artists.ProfessorSo wasit successful? Janet?What do you say?JanetYeah, sure,it was successful. I mean, for one thing, the project established a lot of…uh like community art centersand galleriesand places like ruralareas where people hadn’t really had access to thearts.ProfessorRight.FrankYeah. Butdidn’tthe government end up wasting a lot of money for art that wasn’t even verygood?ProfessorUh…some people might say that. Butwasn’t theprimary objective of the FederalArt Project to provide jobs?FrankThat’s true.Imean…it did provide jobs for thousands of unemployed artists. ProfessorRight.But then when the United Statesbecame involved in the Second World War,unemployment was down and it seems that these programs weren’treally necessary any longer.So, moving on, we don't actuallysee any govern…wellany realgovernment involvement in the artsagain until theearly 1960s, when President Kennedyand otherpoliticians started topush for major funding to support and promotethe arts. Itwas felt bya number ofpoliticians that …wellthat the governmenthad a responsibilityt o support the artsas sort of…oh, what can we say?...thethe soul…or spirit of the country. The idea was that therebe a federal subsidy…um…uh…financial assistance to artists and artistic or cultural institutions. And for just those reasons, in 1965, the National Endowment for the Artswas created.So it was through the NEA,the National Endowment for the Arts, um…that the artswould develop, would be promoted throughout the nation. And thenindividual statesthroughout thecountry started to establish their own state arts councils to help support the arts. Therewas kind of uh…culturalexplosion.And bythe mid 1970s, by 1974 I think, all fifty stateshad their own arts agencies, their own state artscouncils that work with the federalgovernmentwith corporations, artists, performers, you name it.FrankDid you just say corporations? How are theyinvolved?ProfessorWell, you see, corporations aren’t always altruistic. Theymight not support the artsunless…well, unless the government made i t attractive for them to do so,by offering corporations tax incentives tosupport the arts, that is, by lettingcorporations pay less in taxesif theywerepatrons ofthe arts. Um, theKennedyCentre in Washington D.C., you mayuh…maybe you’ve been there,or Lincoln Centrein New York. Bothof these werebuilt with substantialfinancial support from corporations. And the Kennedyand Lincoln centresaren’t the only examples. Manyof your cultural establishments in theUnitedStateswill have a plaque somewhere acknowledging the support – themoneytheyreceived from whatevercorporation. Oh, yes, Janet?JanetBut aren’t therea lot ofpeople who don’t think it’s thegovernment’s role tosupport the arts?ProfessorWell, as a matter offact, a lot ofpoliticians who did not believe in governmentsupport for the arts, theywantedto do away with the agencyentirely, for thatveryreason, to get rid of governmentalsupport.But theyonly succeeded intaking away about half the annual budget. And as far as thepublic goes,well…thereare about as many individuals who disagree with the governmentsupport as thereare those who agree.In fact,with artistsin particular, youhave lots of artistswho support and who have benefited from this agency,although it seems that just as many artistssuppose a government agencybeing involved in the arts, for many different reasons, reasons like theydon’twant the government to controlwhat theycreate.In other words, theargumentsboth for and against government funding ofthe artsare as manyand, and as varied as the individual styles ofthe artists who hold them.源于：小马过河相关推荐：2012年11月18日托福写作真题解析2012年11月18日托福口语真题解析2012年11月18日托福阅读真题解析2012年11月18日托福听力真题解析。

Hereally drives thisargumenthome throughout the essay.When you are reading, I want you to think about that and why thatkind ofthought would be relevant to the readers of his time. Rememberthis is 1838,‘Self-Reliance’was a novel idea at thetime and the United State’s citizenswereless secure about themselvesas individuals and as Americans. Thecountry as a whole was trying to define itself. Emerson wanted to give peoplesomething to reallythink about, help them find theirown wayand what it meantto be who theywere.So that’s something that I thin k is definitely as relevanttoday as it was then, probably, um, especially among young adults likeyourselves, you know,uh, college being a time to sort of reallythink about whoyou are and where you’re going.Now we already said that Emerson really emphasizesnon-conformity, right,asa way to sort of not lose your own self and identityin the world, to have yourown truth and not be afraid to listen to it. Well, he takes thisa stepfurther. Notconforming also means, uh, not conforming with yourself or your past. Whatdoes that mean?Well, if you’ve always been a certain way or done a certainthing, but it’s not working for you anymore,or you’re not content,Emersonsays that it’d be foolish to be consistent evenwith our own past. ‘Focus on t hefuture,’ he says, “That'swhat matters more.Inconsistency is good.”He talksabout a ship’s voyage and this is one of themost famous bits oftheessay - how the best voyage is made up of zigzag lines. Up close, it seemsalittle all over theplace, but from fartheraway, the truepath shows and in theend it justifies all theturns along the way.So, don’t worry if you are not surewhere you’re headed or what your long-term goals are.Staytrue to yourselfand it’ll make sense in the end. I mean,I can at test tothat. BeforeI was aliteratureprofessor, Iwas an accountant.Beforethat,I was a newspaperreporter.My life is taking some prettyinteresting turns and here I am, veryhappy with my experiencesand wherethey’ve brought me. Ifyou relyonyourself and trust your own talents,your own interest, don’t worry,your pathwill make sense in the end.ConversationNarratorListen to a conversation between a student and a professor.ProfessorHey,Jane, you look like you arein a hurry.StudentYeah, things are a little crazy.ProfessorOh yeah? What’s going on?StudentOh, it’s nothing. Well, since it’s your class, I guess it’s OK. It’s, it’s just I am having trouble with mygroup project.ProfessorAh, yes, due next week.What’s your group doing again?StudentIt’s about United StatesSupreme Court Decisions. We are looking at theimpact of recent caseson propertyrights, municipal land use cases, owningdisputes.ProfessorRight,OK. And i t’s not going well?StudentNot really.I’m worried about othertwo people in my group. Theyare just sittingback, not really doing their fair share ofthe work and waiting for an A. It’s kindof stressing me out,because we aregetting close to thedeadline and I feellikeI’m doing everything for this project.ProfessorAh, the good old free writerproblem.StudentFree writer?ProfessorAh, it’s just a term that describes thissituation, when people in the group seekto getthe benefits ofbeing in a group without contributing tothe work. Anyway,what exactly do you mean when you say theyjust sit back? I mean,they’vebeen following theweekly progress repotswith me.StudentYes, but I feellike I’m doing 90% ofthe work. I hateto sound so n egative here,but honestly, theyare taking credit for things theyshouldn’t take credit for. Likelast weekin the library,we decided to split up theresearch into 3 partsandeach of us was supposed to find sources in the library for our parts. I went offto the stackand found some really good materialfor mypart, but when I gotback to our table,theywere just goofing off and talking. So I wentand gotmaterialsfor theirsections as well.ProfessorUm…you know you shouldn’t do that.StudentI know,but I didn’t want to risk the project going down thedrain.ProfessorI know Teresa and Kevin. I had both ofthem on othercourses. So, I’m familiarwith the workand work habits.StudentI know,me too. That’s why this has reallysurprised me.ProfessorDo you…does your group like your topic?StudentWell, Ithink we’d all ratherfocus on casesthat deal with personal liberties,questions about freedom of speech,things like that.But Ichose propertyrights.ProfessorYou chose the topic?StudentYeah, Ithought it would be good for us, all of us to trysomething new.ProfessorUm…maybe that’s part of theproblem. Maybe Teresa and Kevin aren’t thatexcited about the topic? And since you picked it,have you thought…talktothem at all about picking a different topic?StudentBut we’ve got all the sourcesand it’s due next week. We don’t have time to start from scratch.ProfessorOK, I will letyou go ‘cause I know you are so busy. But you might consider talking to your group about your topic choice.StudentI willthink about it. Gotto run, see you in class.LectureNarratorListen to part ofa lecturein a geology class.ProfessorNow we’ve got a few minutes beforewe leave for today.So I’ll just touch on an inter esting subject that I think makesan important point. We’ve been covering rocks and different types ofrocks for the last severalweeks. Butnext weekwe are going to do something a bit different.And to get started I thought I’d mention something that sho ws how uh…as a geologist, you need toknowabout more than just rocksand the structureof solid matter,moving rocks, you may have heard about them.It’s quite a mystery.Death valley is this desert plane, a dry lake bed inCalifornia surrounded bymountains and on the desertfloor these huge rocks,some ofthem hundreds of pounds. And theymove. Theyleave long trailsbehind them,tracksyou might say as theymove from one point to another.Butnobody has been able to figure out how theyare moving because no one haseverseen it happen.Now there area lot of theories,but all we know for sure is that people aren’t’moving the rocks. Thereare no footprints, no tyretracks and no heavymachinery like a bulldozer…uh, nothing was everbrought in to move theseheavy rocks.So what’s going on? TheoryNO.1 ---Wind? Some researchersthink powerfuluh…windstorms might move the rocks. Most of therocks move in the samedirection as the dominant wind pattern from southwest to northeast.But some,and thisis interesting, move straight west while some zigzag or even move inlarge circles.Um…How can that be?How about wind combined with rain? The ground ofthis desertis made of clay. It’s a desert,so it’s dry.But when thereis theoccasionalrain, the clay gr ound becomesextremelyslippery.It’s hard foranyone tostand on, walk on. Some scientiststheorized that perhaps when theground is slipperythe high winds can then move the rocks. There’s a problemwith this theory.One team ofscientists flooded an area ofthe desert with water,then tryto establish how much wind forcewould be necessary to move therocks. And guess this, you need winds of at least five hundred miles an hour to move just the smallest rocks. And winds that strong have neverbeen recorded. Ever!Not on thisplanet.So Ithink it’s safe to say that that issues has been settled.Hereis another possibility–ice.It’s possible that rain on thedesert floor could turn to thin sheetsof ice when temperaturesdrop at night. So if rocks…uh becomi ngbetter than ice,uh … OK, could a pieceof ice with rocks in it be pushed around by thewind? Butthere’s a problem with thistheory,too. Rockstrapped in ice togetherwould have moved togetherwhen the ice moved. Butthat doesn’talways happen. The rocksseem to take separate routes.Thereare a fewother theories. Maybe the ground vibrates, or maybe theground itself is shifting, tilting. Maybe the rocksare moved bya magnetic force. But sadly all these ideas have been eliminated as possibilities. The re’s just no evidence.I bet you are saying to yourself well, whydon’t scientists just setup video camerasto record what actually happens? Thing is this is a protective wilderness area. So by law that type of research isn’t allowed. Besides, in powerful windstorms, sensitive camera equipment would be destroyed. Sowhycan’t researchers just live therefor a while until theyobserve the rocks’moving? Same reason.So whereare we now? Well, right now we still don’t have any answers. So allthis leads backto mymain point – you need to know about more than justrocks as geologists. The researchersstudying moving rocks, well, theycombine their knowledge of rockswith knowledge of wind, ice and such…umnot successfully, not yet.But you know,theywould even have been able to getstartedwithout uh… earth science understanding – knowledge about wind,storms, you know,meteorology. You need tounderstand physics. So forseveralweeks like Isaid we’ll be addressing geology from a wider prospective.I guess that’s all for today. See you next time.LectureNarratorListen to part ofa lecturein a United Statesgovernment class.ProfessorOK, last timewe were talking about government support for the arts. Who cansum up some of themain points? Frank?FrankWell, Iguess there wasn’t reallyany, you know, official government support forthe artsuntil thetwentieth century. Butthe first attempt theUnited Statesgovernment made to,you know, to support the artswas the FederalArtProject.ProfessorRight,so what can you say about the project?FrankUm…it was started during the Depression, um…in the 1930s to employout-of-work artists.ProfessorSo wasit successful? Janet?What do you say?JanetYeah, sure,it was successful. I mean, for one thing, the project established a lot of…uh like community art centersand galleriesand places like ruralareas where people hadn’t really had access to thearts.ProfessorRight.FrankYeah. Butdidn’tthe government end up wasting a lot of money for art that wasn’t even verygood?ProfessorUh…some people might say that. Butwasn’t theprimary objective of the FederalArt Project to provide jobs?FrankThat’s true.Imean…it did provide jobs for thousands of unemployed artists. ProfessorRight.But then when the United Statesbecame involved in the Second World War,unemployment was down and it seems that these programs weren’treally necessary any longer.So, moving on, we don't actuallysee any govern…wellany realgovernment involvement in the artsagain until theearly 1960s, when President Kennedyand otherpoliticians started topush for major funding to support and promotethe arts. Itwas felt bya number ofpoliticians that …wellthat the governmenthad a responsibilityt o support the artsas sort of…oh, what can we say?...thethe soul…or spirit of the country. The idea was that therebe a federal subsidy…um…uh…financial assistance to artists and artistic or cultural institutions. And for just those reasons, in 1965, the National Endowment for the Artswas created.So it was through the NEA,the National Endowment for the Arts, um…that the artswould develop, would be promoted throughout the nation. And thenindividual statesthroughout thecountry started to establish their own state arts councils to help support the arts. Therewas kind of uh…culturalexplosion.And bythe mid 1970s, by 1974 I think, all fifty stateshad their own arts agencies, their own state artscouncils that work with the federalgovernmentwith corporations, artists, performers, you name it.FrankDid you just say corporations? How are theyinvolved?ProfessorWell, you see, corporations aren’t always altruistic. Theymight not support the artsunless…well, unless the government made i t attractive for them to do so,by offering corporations tax incentives tosupport the arts, that is, by lettingcorporations pay less in taxesif theywerepatrons ofthe arts. Um, theKennedyCentre in Washington D.C., you mayuh…maybe you’ve been there,or Lincoln Centrein New York. Bothof these werebuilt with substantialfinancial support from corporations. And the Kennedyand Lincoln centresaren’t the only examples. Manyof your cultural establishments in theUnitedStateswill have a plaque somewhere acknowledging the support – themoneytheyreceived from whatevercorporation. Oh, yes, Janet?JanetBut aren’t therea lot ofpeople who don’t think it’s thegovernment’s role tosupport the arts?ProfessorWell, as a matter offact, a lot ofpoliticians who did not believe in governmentsupport for the arts, theywantedto do away with the agencyentirely, for thatveryreason, to get rid of governmentalsupport.But theyonly succeeded intaking away about half the annual budget. And as far as thepublic goes,well…thereare about as many individuals who disagree with the governmentsupport as thereare those who agree.In fact,with artistsin particular, youhave lots of artistswho support and who have benefited from this agency,although it seems that just as many artistssuppose a government agencybeing involved in the arts, for many different reasons, reasons like theydon’twant the government to controlwhat theycreate.In other words, theargumentsboth for and against government funding ofthe artsare as manyand, and as varied as the individual styles ofthe artists who hold them.源于：小马过河相关推荐：2012年11月18日托福写作真题解析2012年11月18日托福口语真题解析2012年11月18日托福阅读真题解析2012年11月18日托福听力真题解析。

托福TPO4综合写作阅读原文文本： Endotherms are animals such as modern birds and mammals that keep their body temperatures constant. For instance, humans are endotherms and maintain an internal temperature of 37°C, no matter whether the environment is warm or cold. Because dinosaurs were reptiles, and modern reptiles are not endotherms, it was long assumed that dinosaurs were not endotherms. However, dinosaurs differ in many ways from modem reptiles, and there is now considerable evidence that dinosaurs were, in fact, endotherms. Polar dinosaurs One reason for believing that dinosaurs were endotherms is that dinosaur fossils have been discovered in polar regions. Only animals that can maintain a temperature well above that of the surrounding environment could be active in such cold climates. Leg position and movement There is a connection between endothermy and the position and movement of the legs. The physiology of endothermy allows sustained physical activity, such as running. But running is efficient only if an animal's legs are positioned underneath its body, not at the body's side, as they are for crocodiles and many lizards. The legs of all modern endotherms are underneath the body, and so were the legs of dinosaurs. This strongly suggests that dinosaurs were endotherms. Haversian canals There is also a connection between endothermy and bone structure. The bones of endotherms usually include structures called Haversian canals. These canals house nerves and blood vessels that allow the living animal to grow quickly, and rapid body growth is in fact a characteristic of endothermy. The presence of Haversian canals in bone is a strong indicator that the animal is an endotherm, and fossilized bones of dinosaurs are usually dense with Haversian canals. 托福TPO4综合写作听力原文文本： Many scientists have problems with the arguments you read in the passage. They don't think those arguments prove that dinosaurs were endotherms. Take the polar dinosaur argument. When dinosaurs lived, even the polar regions, where dinosaur fossils have been found, were much warmer than today, warm enoughduring part of the year for animals that were not endotherms to live. And during the months when the polar regions were cold, the so-called polar dinosaurs could have migrated to warmer areas or hibernated like many modern reptiles do. So the presence of dinosaur fossils in polar regions doesn't prove the dinosaurs were endotherms. Well, what about the fact that dinosaurs have their legs placed under their bodies, not out to the side like crocodiles. That doesn't necessarily mean dinosaurs were high-energy endotherms built for running. There is another explanation for having legs under the body. This body structure supports more weight, so with the legs under their bodies, dinosaurs can grow to a very large size. Being large had advantages for dinosaurs, so we don't need the idea of endothermy and running to explain why dinosaurs evolved to have their legs under their bodies. Ok, so how about bone structure? Many dinosaur bones do have Haversian canals, that's true. The dinosaur bones also have growth rings. Growth rings are thickening of the bone that indicates periods of time when the dinosaurs weren't rapidly growing. These growth rings are evidence that dinosaurs stopped growing or grew more slowly during cooler periods. This pattern of periodic growth, you know, rapid growth followed by no growth or slow growth, and then rapid growth again, is characteristic of animals that are not endotherms. Animals that maintain a constant body temperature year-round as true endotherms do grow rapidly even when the environment becomes cool. 托福TPO4综合写作满分范文： The professor actually contradicts the statements made in the passage. She is of the view that dinosaurs are not endotherms i.e. they were not able to keep their body temperature at a constant rate. The professor contradicts the issue of dinosaurs being endothers based on the availability of fossils being available in the polar regions, she say that the polar regions in those days were not as cold as they are today i.e at least warm enough for dinosaurs to live. Durin harsh winters she says that there is a possibility of the dinosaurs actually migrating to warmer regions. The issue of leg position and movement being used as a reason to clasify the dinosaurs as endotherms does not please the professor either. She says that dinosaurs had legs under their bodies to support their huge bodies i.e the legs under the body of the dinosaur were actually to support the huge weight of the dinosaur and not to provide it with a body structure like endotherms(which is actually suited for running). The professor acknowledges the presence of haversian canals but also points out that that the fossils show the presence of growth rings. These rings occur due to the thickening of the bone. The thickening indicates that the dinosaurs were’nt。
