文末教你如何使用这个材料！TPO19 综合写作听力+阅读原文ReadingMany consumers ignore commercial advertisements. In response, advertising companie s have started using a new tactic, called “buzzing." The advertisers hire people,buzzers,who personally promote (buzz) products to people they know or meet. The key part is that the buzzers do not reveal that they are being paid to promote anything. They behave as though they were just spontaneously praising a product during normal conversation. Buzzing has generated a lot of controversy, and many critics would like to see it banned.First, the critics complain that consumers should know whether a person praising a product is being paid to praise the product. Knowing this makes a big difference: we expect the truth from people who we believe do not have any motive for misleadingus. But with buzzing what you hear is just paid advertising, which may well give a person incorrect information about the buzzed product.Second, since buzzers pretend they are just private individuals, consumers listen to their endorsements less critically than they should. With advertisements in print or on TV, the consumer is on guard for questionable claims or empty descriptions such as "new and improved." But when consumers do not know they are being lobbied, they may accept claims they would otherwise be suspicious of. This may suit the manufacturers, but it could really harm consumers.And worst of all is the harmful effect that buzzing is likely to have on social relationships. Once we become aware that people we meet socially may be buzzers with a hidden agenda, we will become less trustful of people in general. So buzzing will result in the spread of mistrust and the expectation of dishonesty.ListeningHi, my name is Bill. Um, I was talking your professor in the subway about the great phone service that I was using. And it turned out we’re both interested in marketing. So he asked me to talk in his marketing classes. You see, I am a buzzer, part time, you know. During the day, I’m a student just like you. Now, I read that piece attacking buzzing, it is really misleading. How would it describe buzzing leading a lot, and gives a wrong impression?First, it makes it sound like buzzers don’t tell the truth about the products they’re buzzing. That’s not true. How buzzing works this. Companies find people who use their products and who really think product is good. So buzzing is not like ordinary advertisement where an actress is paid to read some lies. Um, yes, I get paid for telling you what I am thinking, but you get the truth from buzzers. I really do think my phone service is great. That is why the company hired me.Second, the reading makes it seem that when a buzzer talks to someone, the person believes whatever they hear from the buzzer. Not true. In fact, the opposite is true. People I talk to ask a lot of questions about the products I buzz, that is about the price, ser vice and how long I used the product. If I don’t have good answers, they won’t buy the products.Finally, if you believe what you read, buzzing will destroy civilization, that is stupid. If a product is bad, the company can’t recruit buzzers. So what you get from a buzzer is not only sincere but is likely to be about a good product. If you try the phone service I use, you’re gonna love it. So people who try buzzed products are going to have a good experience. So end up being more trustful and open up to people.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。

TPO 19 Lecture 3 Marine Biology(Plant Life in Salt Marshes)NarratorListen to part of a lecture in a marine biology class.Professorfor plants.The water is salty, there is little shade and the ocean tide comes in and out, constantly flooding the marsh, so the variety of plants found in salt marshes is limited, (交代环境恶劣）but there is a plant genus that thrives there, the Spartina. In fact, the Spartina genus is the dominant plant found in salt marshes. (考点: 转折。
引出主旨。
) You can find one type of the Spartina, Saltmarsh Cordgrass, growing in low marsh areas. In higher marsh areas, you are likely to find a Spartina commonly called Salt- meadow Hay. So how is the Spartina able to survive in an envrionment that would kill most plants? well, it is because salt marsh grasses have found ways to adapt to the conditions there. (考点:自问自答。

托福TPO19口语Task6听力文本： Listen to part of a lecture in a biology class. (female professor) Today, I want to talk about sea birds. Now, sea birds hunt and eat fish and, well, their food can be hard to find because their food source is spread out over a large expanse of water. So what sea birds have done is that, over time, they've made adaptations: they've developed special characteristics that help them find food.One adaptation involves the length of the bird's wings. Take albatross, for example, is a large sea bird that spends most of its life flying over ocean waters in search of food, fish to feed itself and to carry back to the nest for its chicks. Now, most birds flap their wings up and down when they fly, which uses up a lot of energy, but the albatross has these special long wings that it can hold perfectly still. It's able to fly without moving its wings up and down. These long wings allow it to glide or float on the wind, and this uses very little energy. This is important because as I said the albatross has to cover huge expanse of ocean to locate food, sometimes up to eleven hundred miles a day. Because of its long wings, it can glide along over the ocean using little energy as it searches for food. Another important adaptation of many sea birds is an acute, highly developed sense of smell. Take the fulmar, like the albatross, the fulmar needs to find foods that scatter far out over the ocean, but the fulmar has a rather unusual advantage: it has tiny tubes inside the nose holes in its beak, and these special tube-shaped nostrils help it to pick up scent of food. Now, this highly-developed sense of smell is especially important because the fulmar ’s main source of food, plankton, are tiny organisms that are hard to see, but they give off a very sharp, distinctive odor, so when fulmars are flying around looking for food, they may not be able to see them, but they can find the plankton by smelling them even from far away. 托福TPO19口语Task6题目： Using the examples of the albatross and the fulmar, explain two special adaptations that have developed to help sea birds find food. 托福TPO19口语Task6满分范文： In order to overcome the difficulties locating food in the vast ocean, some sea birds have developed some adaptations. The first one is the length of the wings. For example, the albatross is a sea bird that flies over the ocean waters looking for fish to feed itself and its kids. It has unusually long wings that can help it glide over the sea, so it can save a lot of energy while traveling a large distance for food. The second one is acute sense of smell. For example, fulmar has special tubein its nostril/nose hole to help it pick up the scent of its food, plankton. The plankton is very tiny so the fulmar cannot see it, but it gives out a special odor that fulmar's nose is sensitive to, and thus when the fulmar recognizes the smell of the plankton, it can locate and eat the plankton easily.

This is contributing to the rise of diabetes, a condition thataffects 422 million people and is fast becoming a major problem, especially in poor countries.Two factors are critical for the successful treatment of diabetes patients. First is a correct diagnosis of the typeof the disease, and second is the administration of the appropriate drugs.A misdiagnosis and, consequently, the wrong treatmentcan cause many problems.“If you label someone who actually has type 2 diabetesas type 1, they'll be left on insulin for the rest of theirlife when they don't need it," said Dr. Richard Oram of theU.K. National Institute for Health Research. "Even worse, if someone with type 1 diabetes is mislabeled as having type 2 diabetes, then they may not be treated with the insulin they need, and they may suffer life-threatening complications.”A new, less expensive test, developed at the Universityof Exeter Medical School, measures 30 genetic variants in the patient’s DNA and calculates the risk for type 1 or type 2.Individual diagnoses can be completed with a commonly used test for antibodies.Scientists are now trying to develop an even simpler DNA-based test that could be done with a smartphone app.No more injections?In the meantime, researchers in South Korea are developing a nanotechnology-based adhesive strip that takes away pain and stress of daily injections for diabetes patients.“The device is a patch type that enables [diabetics] to monitor blood sugar levels via sweat without taking blood samples and injections, as well as to control glucose levels by injecting medication,” said Kim Dae-hyeong, a professor in the School of Chemical and Biological Engineering at Seoul National University.The patch is studded with microneedles that painlessly enter subcutaneous tissue. When the connected chip sensesthat the level of glucose has risen above normal, a small heating element dissolves medication and releases it into the bloodstream.Tests done on lab mice were promising, so scientists hope they will soon start testing the patch on humans. Inthis phase, experiments are still expensive, but scientists say the price will drop once it the patch is ready for mass production.。

托福TPO19听力Conversation1文本 Narrator: Listen to a conversation between a student and the professor. Student: Hi, professor Handerson. That was a really interesting lecture in class today. Professor: Thanks, Tom. Yeah, animals’ use of deception, ways they play tricks on other animals, that’s a fascinating area. One we are really just starting to understand. Student: Yeah, you know, selective adaptations over time are one thing. Oh, like, non-poisonous butterflies that have come to look like poisonous ones. But the idea that animals of the same species intentionally deceive each other, I have never heard that before. Professor: Right, like, there are male frogs who lower their voices and end up sounding bigger than they really are. Student: So they do that to keep other frogs from invading their territory? Professor: Right, bigger frogs have deeper voices, so if a smaller frog can imitate that deep voice. Well ... Student: Yeah, I can see how that might do the trick. But, anyway, what I wanted to ask was, when you started talking about game theory. Well, I know a little bit about it, but I am not clear about its use in biology. Professor: Yeah, it is fairly new to biology. Basically, it uses math to predict what an individual would do under certain circumstances. But for example, a business sells, oh computer, say, and they want to sell their computers to a big university. But there is another company bidding too. So, what should they do? Student: Well, try to offer the lowest price so they can compete, but still make money. Professor: Right, they are competing, like a game, like the frogs. There are risks with pricing too high, the other company might get the sale; there is also the number and types of computers to consider.Each company has to find a balance between the cost and benefits. Well, game theory creates mathematical models that analyze different conditions like this to predict outcomes. Student: Ok, I get that. But how does it apply to animals? Professor: Well, you know, if you are interested in this topic, it would be perfect for your term paper. Student: The literature review? Professor: Yeah, find three journal articles about this or another topic that interests you and discuss them. If there is a conflict in the conclusions or something, that would be important to discuss. Student: Well, from what I have looked at dealing with game theory, I can’t say I understand much of the statistics end. Professor: Well, I can point you to some that presents fairly basic studies, that don’t assume much background knowledge. You’ll just need to answer a few specific questions: What was the researchers’ hypothesis? What did they want to find out? And how did they conduct their research? And then the conclusions they came to. Learning to interpret these statistics will come later. 托福TPO19听力Conversation1题目 1.Why does the man go to see the professor? A. To ask for help in choosing a topic for his term paper. B. To ask the professor to explain how to complete an assignment. C. To ask about a point raised in a recent lecture. D. To offer to help the professor with her research project. 2.Why does the professor mention male frogs that lower their voices? A. To give an example of a behavior that can be predicted using game theory. B. To reinforce the definition of "selective adaptation". C. To give an example of deceptive behavior in animals. D. To compare the behavior of butterflies and frogs. 3.Why does the professor talk about computers?。

12月19日托福听力真题答案及解析12月19日托福听力真题对话：学生服务场景女生丢了register card，没了就不能去博物馆看展览，因为本来需要写agricultural的论文，她去傅物馆找素材。
这礼拜不去傅物馆就要买computer就要关门了。
所以需要一个新的卡，然后老师以为她没有通过email发给他表格, 后来想起来女生己经填过了表格，然后说如果要新的卡需要预约，然后拍照什么的才能办理，但是因为她很着急，工作人员说就给她办了个临时的，女生说要去教授那里说她丢了card的事情，男的说今天我们这里关门了，你明后天应该能拿到正式的卡片。
讲座：社会科学科技和社会发展之间的关系。
科技有时候会独立影响社会的发展，比如在打印机出来以后，德国人读写能力进步很大，开始强调版权什么的。
教授说其实有些影响很远，比如说工业革命。
因为有了打印机科学家交流变多，才得以工业革命的发展，这里看起来所有的影响都是积极的，其实没有什么积极不积极，只是它有一定影响。
但是这个理论现在很不全面，因为有的科技就算己经有了但是也需要等人们可以接受了才会开始发展，举了古代的希腊的发明的例子，因为当时认为写实主义不好，所以photo就没发展起来，后来到了1900年的欧洲，举了斯卡布罗集市那个油画，说明当时人们想记录一下平日的瞬间生活，这个时候写实主义达到了可以接受科技photograph的时候，科技才能促进社会进步。
讲座：自然科学海洋的水为什么流动的，生物学解释，先说有湿水也有热水形成对流然后举了新观点说是鱼群游动时候推的，女生问是不是鲸鱼推的多，它们的尾巴一摆就直接mix了，教授说小鱼群数目多，他们游动时候水流也很快。
教授举了jellyfish ，说实验给它染色，每一次游动它都会把原来有颜色的水带走一部分，然后还说了水母只在晚上活动，白天在海洋里休息。
因为怕捕食者。
它们的活动还会给海面上带来很多浮游植物，它们产生的CO2让大气变暖同时给海洋保溫。

托福TPO19口语Task4阅读文本： Social Learning One way people learn is by watching the behavior of others. Sometimes called social learning, this type of learning involves the process of learning to copy – or not copy – the action of another. By observing the results, or consequences, of another’s behavior, people learn, over time, to either imitate or avoid imitating that behavior. In general, people tend to imitate the behavior of another when they see that it leads to a desirable consequence – hoping to repeat it for themselves. Of course, the opposite is also true – people tend to avoid imitating the behavior of another when they see it result in an undesirable consequence. 托福TPO19口语Task4听力文本： Now listen to part of a lecture in a psychology class. (male professor) OK, so an example to illustrate this, uh, you've often see this happen in families, let's say, there're these two kids, a sister and the brother. Uh, let's say the girl is six and the boy's four, and one day they're all out shopping with their mother, and they're in the store, and the girl sees a toy she wants. She asks her mother to buy, uh, to buy the toy for her but the mother says “no.” So, what does the little girl do? She starts crying and screaming and, you know, “Mommy, I want this!” And, finally, Mom gives in and says, “OK, fine, you can have it,” and buys the girl the toy.Now, don't forget, the little brother's there and he's watching all this happen, and maybe he sees these sorts of thing happen a lot, as mother giving in when his sister cries and screams. What do you think he's going to start doing when he wants something from Mom? He'll probably cry and scream, right?But, what if the opposite happened? Say Mom didn't give in and didn't buy the girl the toy, if fact, say, the Mom instead disciplined the girl for screaming and crying when they got home she didn’t let the little girl watch her favorite TV program. Again, the little boy is watching. Now, what’s the little boy likely to do if he finds himself in a similar situation and he wants Mom to buy him something? Chances are, he’s not gonna cry and scream. Right? 托福TPO19口语Task4题目： Use the examples from the lecture to explain the concept of social learning. 托福TPO19口语Task4满分范文： Sometimes people learn by watching the behavior of others, which is called social learning. And according to the professor there're two situations of this. When people realize that the behavior may lead to desirable consequence, they're likely to copy it. For example, a 4-year-old boy goes out shopping with his mother and his 6-year-old sister. And he sees how his sister gets the doll she wants by crying after their mother refuses her request to buy one. So next time the boy wants to get something he likes, he probably will do that, too. However, when people realize that the consequence is undesirable, they will not copy the behavior. Back to the boy, if his sister doesn't get the toy and is even punished later at home, like that their mother doesn't allow her to watch her favorite TV program, the boy probably won't scream or cry the next time he wants something from his mother. This is how social learning influences the boy's behavior. (171 words) 以上是给大家整理的托福TPO19口语Task4阅读文本+听力文本+题目+满分范文，希望对你有所帮助!。
