新托福听力场景-地球环境学科解题技巧详解

新托福听力场景-地球环境学科解题技巧详解在之前的文章中，有为考生们讲解过地理地质学的内容，在本篇，我们进一步来研究一下地球环境学科。

前者往往和化学以及考古学有所交叉，后者的内容更接近我们的实际生活或认知，比如环境变化。

当然也会涉及到许多场景词汇，广大考生在备考过程中还是要认真复习备考。

下面将带领大家具体看一下地球环境学类的听力段子应该如何应对。

一、概述这一学科要求考生们要关注一些时事，并且扩大自己知识面，开拓视野，可以和地理地质学科一起关注。

☆大气环境，例如赤道无风带，大气环流，全球气候变化。

☆地面环境，例如风能，地下水的研究与保护。

☆海洋环境，例如海底热液，潮汐能。

☆其他话题，可能和天文学，生物学，地理地质学等产生交叉。

在此，考生最好能积累背景知识，多浏览一些原汁原味的报刊杂志，比如Scientific Americans、NationalGeographical等等，多积累相关词汇，熟悉发音。

当然，刚才也提到了，新托福听力段子所涉及的话题往往千变万化且有所交叉，考生在熟悉背景知识的同时也要打牢基础，培养快速辨音能力和短时记忆能力，才能以不变应万变。

二、案例分析请看一个地球环境学的经典案例：E.G.TPO17 Milankovitch Hypothesis听力原文：1) Ok, so we have been talking about theories that deal with the effects ofhuman activity on the climate. But today I’d like to talka little bit aboutother theories that canexplain variations in climate. And one of the best-knownis called the Milankovitch HypothesisQ:What is the lecture mainly about?AA hypothesis that explains how changes in Earth’s motions affectclimate.BA hypothesis that explains why the shape of earth’s orbit varies overtime.CReasons it is difficult to find evidence to support hypotheses about theclimate.DAnalyses of the accuracy of data collected in different ways.分析：这是一道简单的主旨题。

2018年6月23日托福机经真题回忆

【导语】距离6⽉23⽇的托福考试还有不到⼀周的时间，⼤家是否已经做好准备了呢?在考试前⼣，不妨来看看考前的机经，辅助⼤家更好地练习⼀些托福考试的题⽬，做好考前的冲刺。

下⾯就让我们⼀起俩看看详细的内容吧! 【听⼒】 1.⽜顿对诗⼈的影响，什么以前光对应darkness，现在因为的论光学什么的，诗⼈全都写⽜顿体可分解光，⽽且这破书拿英语⽽不是神马拉丁⽂写的，⽽且这破书谁都看得懂，不是科学体 2.什么diamond，有⿊砖⽯，地球上只有两处有，不是地球天然的，⽽是天上掉下来的，没有听仔细，⿊砖是是粗糙的表⾯，多孔的。

3.找管理员问东西没了，可能在别的storage，答应尽快答复 4.找⽼师要推荐信，⽼师很热情，说的很快，⽼师帮忙练习那个项⽬并且系⾥给加学分听⼒ plan2 1.第⼀段超简单，后⾯越来越难，我最后⼀个简直就是听的云⾥雾⾥。

有两段话⽤的是同⼀个教授的突破，教授的特点是，发⾳很奇怪，说话很快，基本是⼀个⾳调。

第⼀段讲有个学⽣去找⾷宿部的⽼师，问学⽣都有哪些⾷宿计划。

主旨题，问学⽣为什么去找⽼师，谈话的主题是什么⽼师回答有三种，195，95和另外⼀种。

学⽣问。

下学期他可以选择的那种吗⽼师答,不可以，那是给3/4年级的学⽣准备的学⽣问，为什么只给⾼年级的同学准备⽼师答，⾼年级的学⽣可以不住在校内，并且劝这个学⽣趁着能住在校内，好好利⽤学校的设施。

学⽣问，为什么他的⽗母给他选了195 的那种。

⽼师答，她认为绝⼤多数⽗母都希望第⼀学期孩⼦不会为⾷宿发愁，所以宁愿选最贵的，不会让学⽣遇到不够吃的问题。

(这⾥有题，问⼀半⽗母第⼀年为什么为学⽣选最贵的) 学⽣问，那我的卡⾥还剩下很多钱怎么办。

⽼师答，可以请你的朋友来吃饭。

学⽣答，他的朋友都遇到同样的情况，⼤家都有很多钱吃不完。

学⽣问，能不能把钱退出来，或者挪到下学期⽤。

⽼师答，不可以。

学校有相关规定，不能退钱，或者下学期接着⽤。

TPO14Lecture1PsychologyProfessor：We’ve said that the term“Cognition”refers to mental states like:knowing and believing,and to mental processes that we use to arrive at those states.So for example, reasoning is a cognitive process,so it’s perception.We use information that we perceive through our senses to help us make decisions to arrive at beliefs and so on.And then there are memory and imagination which relate to the knowledge of things that happen in the past and may happen in the future.So perceiving,remembering,imagining are all internal mental processes that lead to knowing or believing.Yet,each of these processes has limitations, and can lead us to hold mistaken believes or make false predictions.T ake memory for example, maybe you have heard of studies in which people hear a list of related words.Ah…,let`s say a list of different kinds of fruit.After hearing this list,they are presented with several additional words.In this case,we`ll say the additional words were“blanket”and“cheery”.Neither of these words was on the original list,and,well,people will claim correctly that“blanket”was not on the original list,they’ll also claim incorrectly that the word“cheery”was on the list.Most people are convinced they heard the word “cheery”on the original list.Why do they make such a simple mistake?Well,we thinkbecause the words on the list were so closely related,the brain stored only the gist of what they heard.For example,that all the items on the list were types of the fruit.When we tap our memory,our brains often fill in details and quite of ten these details are actually false. We also see this“fill-in”phenomenon with perception.Perception is the faculty that allows us to process information in the present as we take it via our senses.Again,studies have shown that people will fill in information that they thought they perceived even when they didn`t.For example,experiments have been done where a person hears a sentence,but itis missing the word,that logically completes it.They’ll claim to hear that word even though it was never said.So if I were to say…er…the sunrise is in the…and then fill to complete the sentence,people will often claim to have heard the word“east”.In cognitive psychology,we have a phrase for this kind of inaccurate“filling in of details”---it’s called:A Blind Spot.The term originally refers to the place in our eyes where the optic nerve connects the back of the eye to the brain.There are no photo receptors in the area where the nerve connects to the eye.So that particular area of the eye is incapable of detecting images.It p roduces“A Blind Spot”in our field vision.We are unaware of it, because the brain fills in what it thinks belongs in its image,so the picture always appears complete to us.But the term“blind spot”has also taken on a more general meaning---it refers to people being unaware of a bias that may affect their judgment about the subject. And the same“blind-spot phenomenon”that affects memory and perception also affects imagination.Imagination is a faculty that some people use to anticipate future events in their lives.But the ease with which weimagine details can lead to unrealistic expectations and can bias our decisions.So…er…Peter,suppose I ask you to image a lunch salad,no problem,right?But I bet you imagine specific ingredients.Did yours have tomatoes,Onion,Lettuce?mine did?Our brains fill in all sorts of details that might not be part of other people’s image of a salad,which could lead to disappointment for us.If the next time we order a salad in a restaurant,we have our imagined salad in mind,that’s not necessarily what we’ll get on our plate.The problem is not that we imagine things,but that we assume what we’ve imagined is accurate.We should be aware that our imagination has this built-in feature, the blind spot,which makes our predictions fall short of reality.《心理学》教授：我们已经说过，“认知力”指的是这样的精神状态：熟悉某事并相信它确实存在，精神层面上我们曾经达到这样的状态。

TPO 14 Lecture 1 PsychologyNarrator:Listen to part of a lecture in a psychology classProfessor:We’ve said that the term “Cognition” refers to mental states like: knowingand believing, and to mental processes that we use to arrive at those states. Sofor example, reasoning is a cognitive process, so is perception. We useinformation that we perceive through our senses to help us make decisions, toarrive at beliefs and so on. And then there are memory and imagination whichrelate to the knowledge of things that happen in the past or may happen in thefuture. So perceiving, remembering, imagining are all internal mental processesthat lead to knowing or believing.Yet, each of these processes has limitations and can lead us to hold mistakenbeliefs or make false predictions.Take memory for example, maybe you have heard of studies in which people heara list of related words. Um…, let`s say a list of different kinds of fruit.After hearing this list, they are presented with several additional words. Inthis case, we`ll say the additional words were “blanket” and “cherry”. Neitherof these words was on the original list, and while people will claim correctlythat “blanket” was not on the original list, they’ll also claim incorrectly thatthe word “cherry” was on the list. Most people are convinced they heard the word“cherry” on the original list. Why did they make such a simple mistake? Well, wethink because the words on the list were so closely related, the brain storedonly the gist of what it heard. For example, that all the items on the list weretypes of fruit. When we tap our memory, our brains often fill in details andquite often these details are actually false.We also see this “fill-in” phenomenon with perception. Perception is thefaculty that allows us to process information in the present as we take it invia our senses. Again, studies have shown that people will fill in informationthat they thought they perceived even when they didn`t. For example, experimentshave been done where a person hears a sentence, but it is missing the word thatlogically completes it. They’ll claim to hear that word even though it was neversaid. So if I were to say…er…the Sun rises in the…and then fail to complete thesentence, people will often claim to have heard the word “east”.In cognitive psychology, we have a phrase for this kind of inaccurate“filling in of details”--- it’s called: A Blind Spot. The term originally refersto the place in our eyes where the optic nerve connects the back of the eye tothe brain. There are no photoreceptors in the area where the nerve connects tothe eye. So that particular area of the eye is incapable of detecting images.Itproduces “A Blind Spot” in our field of vision. We aren’t aware of it, because the brain fills in what it thinks belongs in the image, so the picture always appears complete to us. But the term “blind spot” has also taken on a more general meaning--- it refers to people being unaware of a bias that may affect their judgment about a subject.And the same “blind-spot phenomenon” that affects memory and perception also affects imagination. Imagination is a faculty that some people use to anticipate future events in their lives. But the ease with which we imagine details can lead to unrealistic expectations and can bias our decisions.So…um…Peter, suppose I ask you to imagine a lunch salad, no problem, right?But I bet you imagine specific ingredients. Did yours have tomatoes, Onion, Lettuce? mine did. Our brains fill in all sorts of details that might not be part of other people’s image of a salad, which could lead to disappointment for us. If the next time we order a salad in a restaurant, we have our imagined salad in mind, that’s not necessarily what we’ll get on our plate. The problem is not that we imagine things, but that we assume what we’ve imagined is accurate. We should be aware that our imagination has this built-in feature, the blind spot, which makes our predictions fall short of reality.。

托福TPO听力：TPO-17 Lecture 2 环境科学

托福TPO听力：TPO-17 Lecture 2 环境科学There is a third movement the hypothesis covers called precession. Precession, basically is the change in the direction of earth's axis of rotation. It will take me a million years to explain even just the basics of this movement as precession is quite complex. And all thesedetails are way beyond our scope. What's important for you to understand is these three movements, well, they are cyclical, and they work together to form, to produce complex but regular variations in earth's climate, and lead to the growth or decline of glaciers. Now, when Milankovitch first proposed this theory in the 1920s, many of his colleagues were skeptical. Milankovitch didn't have any proof. Actually there wouldn't be any evidence to support his hypothesis until the 1970s, when oceanographers were able to drill deep into the seafloor and collect samples, samples which were then analyzed by geologists. And from these samples they were able to put together a history of ocean temperatures going back hundreds of thousands of years, and this showed that earth's climate had changed pretty much the way Milankovitch's hypothesis suggested it would. So this evidence was pretty strong support for the Milankovitch Hypothesis. And by the 1980s, most people accepted this theory.假说还包括了第三种名为“旋式推动”运动。

托福听力加试大王花Rafflesia原文及试题答案

托福听力加试大王花Rafflesia原文及试题答案RafflesiaListen to part of a lecture in a Botany classP: We've been talking about plant classifications and how species belong to a family and families belong to an order, but sometimes, figuring out how we assign certain plant species to a particular order is challenging, even if the plant has...unusual characteristics. You'd think that plants with similar characteristics would belong to the same order, but that's not always true. A good example of this is a flower, that is—a flowering plant—that grows only in Malaysia and Indonesia, called Rafflesia.As you can see, Rafflesia is a pretty unusual plant. For starters, it's huge. The flower can grow up to a meter in width and can weigh up to seven kilos—pretty big, huh There aren't any other specimens in the plant world that have flowers even close to this size. But that's not the only unusual characteristic of Rafflesia, in fact, that's probably one of the least strange features of the plant.The plant also emits a terrible stench, like rotting meat. But again, there are other plants with bad smelling flowers. And in the case of Rafflesia, flies are attracted to that smell, and that's how the flowers get pollinated. So...um...Rafflesia's flowers are huge and smelly. Rafflesia is also a parasite; it gets its energy from another plant instead of from the sun, which is unusual, but not unheard of in the plant kingdom. It actually grows inside its host, which is a type of grapevine. I mean... it grows inside its host until it blooms—it doesn't bloom inside the host. But that leads me to...I want to tell you really quickly about another plant, a plant that's also from the forests of Southeast Asia, called Mitrastema.Now, Mitrastema is also a parasite, which led some to believe that Rafflesia was related to Mitrastema—that they belong to the same order. Mitrastema as I said is a parasite, but its flowers are much smaller, and don't smell bad, so you can see why there was debate about whether they were related. But as it turns out, Mitrastema is actually related to blueberries. So, even plants that share an unusual characteristic with Rafflesia are not related to it. And, um...no plant shares all three of its unusual characteristics, and that made classifying Rafflesia very, very difficult.Now, you're probably thinking, why don't they just analyze the DNA of the plant Well, as I said, Rafflesia is a parasite. It lacks the leaves; the green tissue that most plants need for photosynthesis. It's unable to...um...to capture the sunlight most other plants use to make food. So, it's lacking...it...it...it doesn't have the DNA—the genes—for photosynthesis, which is what we usually use to classify plant species. But some researchers in Michigan persisted, and analyzed about 90 species of seed plants and compared them to Rafflesia, and we finally had an answer. Rafflesia was part of the Malpighiales order.Now, other species in the Malpighiales order includeviolets...um...poinsettias...uh...passion-flowers...what else Willows. So it was pretty unexpected because flowers like violets are a lot smaller than Rafflesia, right And they don't smell bad—they don't smell like rotting meat...and they're not parasitic. It took almost 200 years to classify Rafflesia, to identify its relatives, and I don't think anyone would have ever guessed that it's in the order Malpighiales. I mean...you know-it'd be nice to be able to classify species based on their obvious characteristics, but, it didn't work that way with Rafflesia. And unfortunately for Rafflesia, and for the field of botany, it seems that Rafflesia may be dying out. It's certainly endangered because of deforestation in its habitat. And to make matters worse, Rafflesia doesn't reproduce very well. First of all, only 10-20% of buds turn intofull-fledged flowers, and it can take them a year to grow. There are also male flowers and female flowers, and one of each has to be in the same area—the same vicinity—at the same time, to produce seeds, and the flies that are attracted to the flower's strong smell have to carry pollen from one flower to the other, so how often do you think these events occur all together Even people who study the plant for years may never witness it.考题:问题一：主旨题What is the lecture mainly about正确答案：(C) 植物的分类困难。

Lecture 1 讲的是玛雅毁灭的原因，有一种说法是干旱。

气候学家说发现了一种G开头是物质(TPO里一个cave 里面提过这种物质)。

在玛雅一个城市附近的lake里，说明气候很干旱。

后来又有研究发现，说是一个城市并不是因为干旱而毁灭的，具体原因忘了。

后来说研究了很多wetland anima，发现大多数都有数量下降。

最后说因为玛雅人砍伐树林过度产生了很严重的后果。

Lecture 2 讲的是很难确定一些物种是不是endangered。

一种生物eel，它在幼虫阶段时在大西洋某个S开头的地方，然后随着洋流到处漂，最后快死的时候又会回到S地产卵，再死去。

很多人觉得eel不应该是endangered，因为它能随着洋流去很多地方，能适应很多环境。

然后又说它是一种C开头的种类，这个种类的生物都是在salt water里出生，生活在fresh water，并且回到salt water产卵。

也有人说，因为不同地方发现的eel数量没法估算整体，所以也没有人知道eel的大概数量。

Conversation 2一个男生在图书馆用电脑遇到些问题，管理员说帮忙查看是不是系统问题，男生说应该不是，只是偶尔会遇到问题，其他都是挺好的，特别是新上的在线图书馆很useful。

然后男生问能否在这儿工作。

管理员说确实在招人，要求是graduate并且熟悉电脑，男生是大三但是电脑很好，整个group还去公司实习过，然后开始说自己团队的东西的优点。

最后管理员说，系统是新安装的，就算有问题也应该很快会修复，并且建议男生就工作问题去咨询另一个人。

Remember there are 32 people in the choir this year.M: We can make it. For our last trip, we got the alumni to make donations and the professor applied for a grant from the Association of Choral Directors.W: Did he put anyone is charge of fund raising?M: Russ. She took care of it last time. She'll probable be calling the choir members to work with her.W: I really hates soliciting donations, but it'll be worth it, this tour is a once-in-a-life-time experience.40. What problem are the speakers discussing?41. What will Russ probably have to do?42. Why will Russ probably be calling the Choir members?Questions 43-46Word comes from California of a new weapon in the war on household pests. Two scientists working for a firm in Annahine, California developed a new method to eliminate insects without using dangerous chemicals. The new poison: hot air. The basic idea is that insect pests cannot adjust to temperatures much above normal. In laboratory experiments, cockroaches and termites can't survive much more than a quarter of an hour at 100 degrees. Ferenhite or about fifty degrees Certigrade. The new method involves covering a house with a huge tent, and filling it with air heated to around 65 degrees Certigrade. Hot air is forced in with fans and the tent keeps the heat inside the house. Since termites must be continued for four to six hours. But when it's all over and the insects are dead, there is no toxic residues to endanger humans or pets, and no funny smells. Scientists claim that there's no danger of fire either. Since very few household materials will burn at 65 degrees Certigrade. In fact, wood is prepared for construction use by drying in the ovens at 80 degrees Certigrade, which is substancially hotter.43. What is the program about?44. What makes the new system better than other treatments?45. Why are the houses covered with tents?46. Why does the announcer mention that construction wood is dried by heat?Question 47-50M: Math Department, Doctor Webster speaking.W: Hello, Prof. Webster, this is Janet Hill calling, I'm living two doors down from your teaching assistant, Don Williams. Don asked me to call you because he has lost his voice and can't talk to you himself.M: Lost his vice. Oh, what a shame! Is there anything I can do for him?W: Well, he has a class this afternoon from two-thirty to four and he won't be able to teach it, but he doesn't want to cancel it either.M: Want me to try to find somebody else to teach the class?W: No, not exactly. What he wants to do is to get someone go in for him, just to pass back the mid-term exams. He's already marked tem and they are on the desk in his office. The whole thing wouldn't take more than ten minutes.M: His classes are two-thirty, eh? Well I'm afraid at that time I was going to be on campus anyway; so I could do it for him. What room is his class in?W: Cader Hall, room two-fourteen. Will you need his office key to get the exams? He's given it to me and I could bring it to you.M: Actually, that won't be necessary. We have a master key in the maths department. So I can get into his office.W: Thank you very much, Prof. Webster. Don doesn't have another class to teach until Thursday, and hopefully, he will be able to talk by then. He'll call you as soon as he can. Oh, yes, I almost forgot. Could you put the next assignment on the board, too. It's all the problems on page forty-five, and they are due at the next class.47. What is Don's problem?48. What favor does Don want someone to do for him?49. What does Janet offer to do?50. What does Janet almost forget to ask professor Webster?。
