Are there figures—people?What are they doing?Or is it a landscape…or an abstract representation of something?Tell what the subject is,and what aspects are emphasized in the painting.This will give your reader an overview of what the work looks like before you analyze it.The next part of your paper—the actual formal analysis—will be the longest and most important section of your paper,where you describe and analyze individual design elements.For this portion of the paper,you're going to rely on the notes you took at the museum,because you should be able to describe in detail the design elements the artist uses,and how they are used.For example,does the artist use harsh lines or soft lines—are the colors bright or muted?Focus on the design elements that you feel are most strongly represented in that particular work of art. And if you don't know where to begin,take note of where your eye goes first.Then describe things in the order in which your eye moves around the work.This will help you understand how one part relates to another—the interaction between the different parts of the work.OK,this kind of analysis should occur throughout the main portion of the paper.In the last section of your paper—and this goes beyond formal analysis—you comment on the significance of what you have seen.What details of the work convey meaning?Some significant details will not be apparent to you right away,but if you look long enough,you realize how important they are for your interpretation of the work.Many years ago,I was writing a formal analysis of a painting of a little boy.In the painting,a little boy was standing in his nursery,and he was holding a toy bird in his hand,and there were more toys around him in the background of the painting. Because of the bird he was holding,I assumed at first that the painting was about the innocence of children.But as I looked at the painting longer,I realized that the boy's eyes looked sad even though there was no discernable expression on his face.And then it dawned on me that,even though he was surrounded by toys,he was all alone in his nursery.The boy's eyes were a significant detail in the painting,that I didn't notice at first.题目1.What point does the professor make about the writing of a formal analysis in art history?A.Its objective is to identify common features of several works of art.B.Its most important part is the explanation of an artwork's significance.C.Several styles of writing a formal analysis are used by art historians.D.A particular approach is required to present Information about an artwork.2.According to the professor,what will students need to do before writing the art history paper?A.Look at examples of formal analysis in textbooksB.Take notes on the artwork they will write aboutC.Go to different museums before selecting a topic for the paperD.Study the historical context of the artwork they will write about3.Why does the professor mention an English class?A.To explain the difference between visual language and written languageB.To explain that students need good writing skills for their assignmentC.To point out similarities between a poetry paper and the students'assignmentD.To point out that many art historians become writers4.What does the professor recommend as a way to understand the relationship between different parts of an artwork?A.Looking for lines that connect different parts of the workB.Examining the artwork from several different anglesC.Looking for similar colors the artist used throughout the workD.Determining how the viewer's eyes move around the work5.Why does the professor talk about his own experience analyzing the painting of a little boy?A.To point out a common misconception about formal analysisB.To stress the importance of looking at an artwork thoroughlyC.To show why a formal analysis should not emphasize small detailsD.To provide an example of an artwork that is easy to analyze6.The professor describes three sections the art history paper should contain.Place them in the order in which they should appear in the paper.Click on a phrase.Then drag it to the space where it belongs.A.Analysis of the design elements the artist usesB.Discussion of the meaning of the artworkC.Summary of the appearance of the artwork答案D B C D B CAB译文旁白：下面听一段艺术史课程的片段。

听力加试完整版(题+部分原文)

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, andanalyzed 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 into full-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.中文背景：大王花Botany教授一开始就介绍植物分类，提到分类中的species种，genus属，order目。

托福听力tpo69 lecture1、2、3 原文+题目+答案+译文Lecture1 (2)原文 (2)题目 (5)答案 (8)译文 (8)Lecture2 (10)原文 (10)题目 (14)答案 (17)译文 (17)Lecture3 (20)原文 (20)题目 (23)答案 (26)译文 (26)Lecture1原文So, we've talked about the plates that form the earth crust and their movements and how in some places they're separating. Now, when this happens in the ocean along a middle ocean ridge, some important things can happen, in particular you can get a hydrothermal vent. This is a lot like a geyser except it’s on the ocean floor.A geyser of course is a kind of eruption from underground hot spring. Water that’s been heated up in Earth’s interior, when under pressure, can erupt, sending that water and steam, shooting upwards through crack in the earth. A hydrothermal vent is essentially this same thing, but the water is emitted out of cracks or, or fractures in the ocean floor. If Forms that don't depend on energy from the sun, but depend on chemical energy.But, the vents are also enormous significance for us. From a purely geological perspective, because the chemistry of the oceans is affected by them. To see how, let’s look at the process a little more closely. They typically occur in fields, so you might have an area with a dozen of them, but you need two things to get one of these fields, first, you got haveheat. And you’ve got have fissures in the ocean floor. So, in a vent field, you've got cracks in the ocean floor. And cold water at the bottom of the ocean, we are talking, maybe two degrees Celsius, goes down into them, as it goes underground, it heats up, because in these fields, there are magma chambers, only a few kilometers below the ocean floor.This hot molten rock heats the solid rock above it to as high as five hundred degrees Celsius. And this heated solid rock, then heats the ocean water that flows over it. Now remember, the high pressure of the deep sea, allows water to stay liquid at such a high temperature, so it can reach temperatures of, three or four hundred degrees Celsius.As the water heated, it rises up through other cracks and it shoots up back into the ocean, much like with geyser on land. Now, the important part, is what the water is carrying with it, as it emerges. The heated water draws minerals from solid rock. So, you get dissolved metals in the water, like iron and copper. When the water shoots up and re-enters the cold ocean, it quickly cools and these minerals precipitate out. They’re released and they are deposited into the ocean water, which affects its composition. And it also creates quite a site, these vents have a plume that looks like a smoke, likes smoke that’s coming up out of the vent in the earth.Remember some of the water coming out of the vents is over threehundred degree Celsius. When it’s this hot, it dissolves sulfur, iron and other metals in the rock and it interacts with. when these minerals precipitate out, the water forms of black plume, so these vents are called black smokers. It's the sulfur and metals precipitating out of the water that that's what causes black color.But there are also white smokers, these emit what looks like a white smoke. That's because their water is relatively cool, above one hundred to three hundred degrees. Still pretty warm, but, not warm enough to dissolve sulfur or iron. Instead, they draw off different minerals from rocks. Things like silica and they give off different color, whitish color, when those minerals precipitate out.But in both black and white smokers as the waters emitted in the plume, the mineral that precipitate out, eventually build up around the vent, forming large, tower, like structures or minerals, build up layer upon layer, we call these chimneys, just like a chimney on a house. Different minerals will tend to build up at different places on the chimneys. But, some of the minerals like silica, a form kind of cement, and they hold the whole structure together. So, they can grow quite large and quite quickly. If you can believe it there was one chimney that reached forty-seven meters, that’s like fourteen story It collapsed, but it’s actually now rebuilding.题目1.What does the professor mainly discuss?A. The process by which molten rock can enter the oceanB. The formation of hydrothermal ventsC. The differences between geysers and hydrothermal ventsD.

And before I got married, I had read numerous books on child rearing and child psychology to try to prepare myself for this transitional phase in my own life, but every family and situation is so unique, and the challenges of raising children are often so complex that not one guidebookcan fully prepare you for what awaits you on the front lines.Interviewer: Yeah, that's for sure. Um, Doctor. How many children do you have?Well, yeah, and they're all unique, and there's never a dull moment around our house.And your book. What do you mean by successful children?Philip: Well, I should first point out that I'm not thinking in terms of the most standard definition, one that associates success with financial or educational gains.Interviewer: Well, what do you mean by success then?Philip: Well, I'm referring to success in understanding and managing children's own emotional, moral, and even spiritual welfare. For example, people, umm . . . people get angry and depressed, and that's a part of life, and just telling kids not to be upset or frustrated denies the naturalness of these feelings, and it doesn't teach children how to cope with their feelings.Interviewer: So, you're saying that it's okay to get angry?Philip: We all do, I mean, are there times when you get angry?Interviewer: Well, yeah. Of course.Philip: Well, that's, I guess, what I'm trying to say . . . is thatwe all get angry, but learning how to express it appropriately is the key. Not to digress here, but if people are expecting a simple, textbook solution to raising and understanding their children, then they don't understand or underestimate the realities of rearing children.Interviewer: I think I see your point. So, for all of us out there struggling to raise our children, what can we, as parents, do to better understand and relate to our children?Philip: When you first get married and promise to love and cherish your spouse, few of us are contemplating, at that moment, the potential challenges we will face five, ten, or twenty years down the road. You don't look over at your spouse, or future spouse, and say, "Well, honey. There's a good chance we will get divorced in a few years." I don't think anyone was thinking that. "Uh. Isn't that any interesting fact?" Of course, this idea is the furthest from our minds, and it might be a blessing that we don't have crystal ball to look into the future.Interviewer: I agree with you there. I think it's best not to know what's coming up.Philip: I think in many cases.Interviewer: I know in my own life. I don't know if I woulddare to do the things that we've needed to do if I had known what was coming down the road.Philip: Exactly. And I think that although we hear stories about the difficulties in raising children, that seems light years away, and we would rather not contemplate that on, well, I think on our wedding days. However, we must face the realities of life sooner or later, and having some skills in your, let's say, your emotional toolbox might provide us with the emotional, physical, and spiritual strength later on when we really need to drawn on it.Interviewer: Like when, for example?Philip: First of all, one should understand that there are many factors that influence how children grow up and develop including the environment around them, genetics, peers, school teachers, and education within the home.Interviewer: Yeah, I can see that all of that really would affect kids.Philip: Exactly. However, as parents, we have more control over some of these than others.I think we also have more control than we realize over some of these factors.Philip: Right, it's just that I think there are variety ofthings---peers are one---but also, within ourselves, we have the the ability to influence, I think, children. However, I think parents often beat themselves up emotionally thinking that must bear all the blame for any of their children's failings. In other words, while parents perhaps have the most impact on our children's decisions and attitudes, we can't ignore the fact that children . . . uh, particularly teenagers . . . tend to follow the popular crowd, and their actions often mirror this.Interviewer: So, what else?Philip: Well, parents need to establish clear boundaries and expectations for your children, and be consistent on how you implement them. I mean, children often see rules as a way to limit their freedom when in fact we're just trying to protect them from often negative consequences of their actions. But when children feel that they're being treated fairly, and we validate their feelings, they'll respond . . . . at least we hope they will respond . . . better to our requests, and in return, they can earn greater latitude in what they are allowed to do, and they no longer see rules and barriers as things that stop them.Interviewer: That makes a lot of sense.Philip: And perhaps, finally, establish good lines of communication with your spouse and children. Being open totheir ideas and lavishing them with specific praise often will build reserves in their emotional bank accounts. And doing this will foster perhaps positive relationships with them. And also telling them you know how they feel---and this is a common mistake that I often make--- "I know how you feel" . . .Interviewer: Yeah, I can remember my mom saying that.Philip: Right, and then we often say that well because we have a billion years of experience will often just sound condescending to them and perhaps push them away, even if teenagers are some of the hardest creatures on the planet to understand.Interviewer: Yeah, I think mine is for sure. Okay, any closing remarks on this topic before we have to go? You make it sound so easy.Philip: Well, there . . . I think there were a number of years I thought about this, but only recently I've decided to pen some of these ideas because there's never a point we, quote "arrive" close quote, at being the ideal parent. I mean it involves a lot of trial and error, missteps, and even pain along the way. And more often than not, valleys of heartache but that accompany peaks of joy. All I can say is that we can never give up on ourchildren, even when they yell and scream in our faces. It's hard, but we just can't take it personally. And if there's one last thing I could say would be to have hope that things will work out.Interviewer: Thank you so much. That sounds like a really important message and important book. Thank you for joining our show today.Philip: Thank YOU.

Drought-tolerant plants are like bears in a way.You know how bears mostly sleep through the winter?They can survive without eating because their metabolism slows down.Well,drought-tolerant plants also go into a dormant state when resources—in their case,water—runs short.A drought-tolerant plant can actually dry out without dying.I said before that most desert rains are light and brief,but occasionally there's a heavy one.Drought-tolerant plants revive after one of these significant rainfalls—and they're able to absorb a good bit of the rainfall due to their deep roots.Actually the root system for drought-tolerant plants is more extensive than the root systems of many plants that live in wetter climates.Drought-tolerant plants can even absorb water from relatively dry soil because of their deep roots,in contrast to succulent plants.The third adaptive strategy is to avoid the drought conditions altogether.Yes,there are plants that do this—annual plants.An annual plant will mature and produce seeds in a single season that will become the next generation of annual plants.In desert conditions,annual plants grow in the fall or spring to avoid the heat of summer and the cold of winter.Of course,these plants could face a serious problem if a particular fall or spring happened to be very dry—they would have difficulty growing and could die before producing seeds.But they have a mechanism to prevent one year of low rainfall from wiping them out. Not all seeds an annual plant puts out will grow the following year.Some seeds remain dormant in the ground for several years.It's a type of insurance that protects the annual plants from a season of poor growing conditions,of unfavorable weather.题目1.What is the lecture mainly about?A.The growth rates of plants in different geographical regionsB.Different ways that plants have adapted to desert environmentsC.The different mechanisms that plant roots use to absorb waterD.Different kinds of succulent plants2.What are two features of succulent plants that help them survive in deserts?[Click on2answers.]A.Succulent plants store water in their leaves and stems.B.Succulent plants become dormant until the next rainfall.C.Succulent plants have short stems.D.Succulent plants have few leaves.3.Why does the professor mention bears?A.To remind students of information from a previous lectureB.To point out a feature common to all desert plantsC.To reinforce a point about drought-tolerant plantsD.To help students understand the concept of adaptation4.What is one ability that drought-tolerant plants have that succulent plants do not have?A.The ability to absorb water from dry soilB.The ability to absorb water through their leavesC.The ability to prevent moisture from being lost through their leavesD.The ability to shed leaves5.Why can annual plants grow in a desert even after a year of no rainfall?A.Annual plants have an extensive root system that can absorb water from far away.B.Annual plants produce seeds all year long.C.Seeds of annual plants can store water for a long time.D.Seeds of annual plants can survive in the ground for a long time without water.5.Listen again to part of the lecture.Then,answer the question.(PROFESSOR)The third adaptive strategy is to avoid the drought conditions altogether.Yes,there are plants that do this.Why does the professor say this: (PROFESSOR)Yes,there are plants that do this.A.To correct a previous statementB.To acknowledge a potentially surprising factC.To anticipate the types of questions that students might have about the topicD.To make sure that students are paying attention答案B ADC AD B译文教授：许多生物已经发展了在恶劣环境中生存的能力：酷热、严寒，或者非常干燥的环境。

Listening ComprehensionSection One：Listening Comprehension听力原文：Listen to a conversation between a student (S) and an American history professor (P).S: Professor Farrington, may I ask a question about something you said in class yesterday?P: Sure.S: You mentioned that... about how Park City in Utah went from a boomtown in the 1800s to a ghost town and then became prospero us again. I was, well... that’s an interesting cycle, and..., well, perhaps it might be suitable topic for my research paper?P: Sure, that might make a good topic since similar things happened at other mining towns.S: So, comparing them might be interesting?P: Yeah, absolutely!S: So, what triggered the economic downturn in Park City?P: Well, in 1870 there were fewer than 200 people living in the Park City area. After silver was discovered there the population grew very quickly. I think it reached around 10,000 by 1900, but soon after that the silver that was close to the surface had all been mined, so they had to dig deeper and deeper, which reduced the profit margin not just because it’s time consuming, but going deeper led to problems with flooding. It’s t ime consuming and expensive to pump water out of mines. So, that was one major factor. I mean there were other factors that contributed too like the recession and a stock marketpanic in 1907. If you do write about this, you have to get into that.S: Ok, and it was what... tourism that brought it back again?P: Basically, yes. The ski industry kind of started about the same time in the 1920s. At first it was only a few folks hiking up to the top of the mountain and then skiing down. As the sportbecame popular, so did the mountains around Park City. By the 1960s, it was a major ski resort with thousands of skiers.S: And the same with the other abandoned mining towns?P: Well, some, but some became tourist attractions not because of skiing, but because people were interested in the history. Actually, one old mining town in the middle of the California desert... Bodie, that’s now a state park. It’s popular because the buildings have been preserved as they were in the 1940s.S: Wow! So, maybe I could choose a couple of towns that went through that whole cycle and talk about them in some depth as a way of illustrating the general boom and bust phenomenon... maybe find some first-hand accounts?P: Well, for this, sure, it’d be better to go into some depth about specific towns rather than talking about a lot of them in broad terms. Definitely give it a shot. But you probably won’t be able to find many diaries or personal accounts. Not many people who lived in mining towns could read or write, Oh, and also remember the impact of national events.S: Ok, that’s understandable, the local and the national. Thanks!。

In particular, behavior patterns can change as an animal becomes adapted to its environment. We can see the results of this in the way that animals have developed different types of feeding behavior. Animals are generally classified as a generalist feeders and specialist feeders. Now, um, these terms are used in a variety of ways. At times, they're used to refer to an animal's range of habitats. I've also seen them used to describe the number of foraging techniques that are used by an individual or species.Um, but for our purposes, we're going to use them to refer to the range of food items that are eaten by a species. So a generalist feeder is a species that eats a wide variety of foods during its lifetime. And a specialist is a species that feeds on a highly restricted number of foods. A good example of a generalist would be a rat. Rats are notorious for eating just about anything that's available, whether it's a plant or an animal. At the other end of the spectrum, we have the koala which eats only the leaves of eucalyptus trees.Okay, now there are advantages to each. For a generalist, If 1 type of food isn't around, it can feed on another that's more abundant. On theother hand, the advantage of being a specialist is that the animal is well adapted to its food. You could say that specialists are feeding masters, their consumption, even their digestive system is just so finely tuned. For instance, take the koala. The eucalyptus leaves that it feeds on, don't contain much protein. What's more, the leaves contain compounds that are poisonous to most species? But the koalas digestive system has adapted to handle this. It's liver deactivates, the poisonous compounds, and its digestive system is designed to extract the maximum amount of nutrients from the leaves.So it's not a question of which strategy is better. The real question is, what determines how selective animal species are in what they eat? Well, the answer may lie in a concept called optimal foraging. The idea is that natural selection favors animals whose feeding behavior has the lowest cost to benefit ratio. That is you want to get the best healthiest food you can. And you want to do it as quickly as possible. And as easily as possible.Now, in a natural environment, no animal forage in an absolutely optimal manner. But, well, I read some research on a little rat called the kangaroo rat, which lives in deserts in North America. The kangaroo rat is a generalist which eats plant matter like seeds and fruit. It lives in deep burrows which provide protection from the desert heat and from predators like hawks or snakes. And it goes foraging at night for food.For plant matter, under the protection of darkness, even though it's a generalist. If the only thing available is seed, if a choice of seeds is available to it, it picks up seeds that provide more energy than those it leaves behind. And it carries them back to its burrow. Once it's there, it might eat only the richest seeds from the ones that brought back. So it selects seeds outside in a way that lets it spend as little time as possible foraging in that risky environment, and then sorts out its food later when it's safely in its burrow.Oh, yes, Kenneth. You have a question?Male student: But what about the koala? It gets by uh, by being even more selective, you'd think you would be really risky to rely completely on eucalyptus leaves. Wouldn't it be better to diversify like the kangaroo rat, and eat, at least one or two other things?Professor: Well, what do you think the koala would say? What do I gain by being so selective? In terms of optimal foraging, it's clear that eucalyptus trees provide an abundant source of food. Other animals can't eat the leaves and think of how little energy the koala uses. It spends only about 3 hours each day eating to get the energy it needs. So being a specialist allows it to get the nutrients it needs with minimal expenditure of energy.题目1.What is the lecture mainly about?A. The reasons why some animals eat only plantsB. The advantages of two different feeding adaptationsC. The variety of foods that certain animals can eatD. The relationship between two animals that share a habitat2.What definition of the term “generalist” does the professor use in the lecture?A. An animal species that eats a wide variety of foodsB.

It obtains all the food it needs in relatively little time.B. It requires large amounts of protein in its diet.C. It can eat leaves that are poisonous to other animals.D. It spends most of its time eating.4.What does the professor imply about the kangaroo rat?A. It will take more risks when foraging for high-energy food.B.

托福听力经典加试题及答案(汇总)

托福听力经典加试题及答案(汇总鸟类迁徙Bird migrationStudent having difficulties in writing term paper原文:Conversation:term paper of bird migrationListen to a conversation between a student and his Biology professor.S: Dr. Russell, I was hoping to discuss my term paper with you I'm getting a little bit stuck here.P: Of course, so...what do you have so far? What's your topic?S: Well, I wanted to write about bird migration, but I'm having trouble finding enough sources.P: You're having trouble finding sources on bird migrationS: No, actually, on the particular aspect of bird migration that I want to write about.The thing is, I wanted to write specifically on early theories of bird migration...describe some of the theories. Like how Aristotle thought that birds changed into different species during the winter. Or how othernaturalists thought that bigger birds carried smaller birds to warmer spots for the wintertime. But I've only got a couple of books to work with right now.P: Hm...I have to admit that it's an interesting topic, and you certainly seem excited by it. But remember I told you all to ask yourselves how yourtopic is going to help you show that you can apply what you've learned this semester.A summary or description is not really what I'm looking for as much as your analysis of a certain topic.S: I guess it's not really what we're supposed to do, huhP: Right. So, how about we think about some other ideas for your paper. I mean you don't need to discard the idea completely... but... take a really different focus. Um... for example...you could present what you think are some reasons-the rationale-behind some of the erroneous theories early naturalists had. But, you'll be supporting your views with current research; those are the sources you'll need to seek out.S: Ok, I think I see what you're saying. So, like today...today we know that lots of small birds migrate at night, but maybe `cause people didn't see them-didn't see the small birds migrating-they only saw bigger birds, like geese migrating during the day. They thought that the big birds were carrying the small ones under their wings.P: There you go! That's exactly what I mean. You're showing that you're thinking about the topic, not just telling me what you read.S: Ok, I also have a really cool example of a migratory bird that I'd like to discuss in my paper. It's the Common Poorwill—I mean it seems that some Ornithologists believe that the Common Poorwill really does hibernate instead of migrating-that it's maybe the only bird that does.P: If I were you, I would stick just with migration research. Remember, this is only a 15-page paper.S: Ok, I see your point.P: But it's great that you're finding this all so interesting. I want you to come back to see me in a week so we can take a look at the new direction in your paper and evaluate the sources you've found in the meantime.中文大意:Male Student:老师,我想跟你讨论一下我的学期论文。

托福听力加试第一套第二篇（大王花）（原文+题+答案）

托福听力加试第一套第二篇（大王花）（原文+题+答案）二. 大王花Listen to part of a lecture in a botany classWe’ve been talking about plant classification and how species belong to 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 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 with an d can weigh up to seven kilos—pretty big, huh? There aren’t any other specimens in the part world that have flowers even close to the size. But that’s not the only unusual characteristic of Rafflesia, in fact, that’s probably one of the least strange featu res 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 the 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 the host. But that leads me to …I want t o 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 believethe Rafflesia was related to Mitrastema—that they belong to the same order. Mitrastema as I said 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 Isaid, Rafflesia is a parasite. It lacks the leaves; the green tissue that most plants need for photosynthesis. It’s unable to …l um. …To capture the sunlight most other plants use to make food. So, it’s lacking …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 include violets… 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 the y 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 toclassify species based on their obvious characteristics, but, it didn’t work that way with.Rafflesia. And unfortunately for Rafflesia, and for the field ofbotany. It seems that Rafflesia may be dying out. It’s certainly endangered because of deforestation in its habitat. And to make matters worse, Rafflesi a doesn’t reproduce very well. First of all, only 10-20％of buds tum into full-fledged flowers and it can take them a year to grow.
