Sometimes, however, problems occur that lead to in accurate results. One such problem is the experimenter effect. ①The experimenter effect occurs when are searcher’s expectations affect the outcome of the experiment. The researcher expects a particular result from the experiment, and that expectation causes the researcher to act in ways that influence the behavior of the experiment participants, thereby invalidating the results of the experiment.Listening Part:Now listen to part of a lecture on this topic in a psychology class.(male professor) ②For example, I recently read about a case in which a researcher was given two groups of monkeys and he was asked to train these monkeys to pick up a ball and put it in a box. And he was told to record how many hours it took to train each monkey to learn to do this.③Now, before he started the training, the researcher was told that one group of monkeys was highly intelligent and the other group was less intelligent. In truth, there was no difference between them. All the monkeys were actually very similar in terms of intelligence. But the researcher didn’t know that. Hethought one group was smarter, so he expected that group would be easier to train.So, what happened? Well, the researcher trained the monkeys to perform the action, and it turned out that.④ On average, it took him two hours less time to train the supposedly smart monkeys than the supposedly less intelligent monkeys. Why? ⑤Well, it turns out that with the supposedly smart monkeys the researcher smiled at them a lot, gave them a lot of encouragement, talked to them a lot, worked hard to communicate with them but with the monkeys he thought were less intelligent, he wasn’t this enthusiastic, he didn’t try this hard, wasn’t quite optimistic.Question:Explain how the example from the professor ’s lecture illustrates the experimenter effect.一.范文The professor talks about experimenter effect which occurs when a researcher’s expectation affect the outcome of an experiment. In the study, researcher was asked to train two groups of monkeys. He was told that one group of monkey was smarter than the other, although they are equally intelligent. It turned out monkeys from the first group took two hours less to train on average. The reason was that the researcher expected the smarter group to be easier to train so he smiled to those monkeys and encouraged them a lot during the training. But he didn’t work as hard with the monkeys from the other group.二.重点词汇1. objective：adj. 客观的;目标的;宾格的Our main objective was the recovery of the child safe and well.2. invalidate：vt. 使无效;使无价值An official decree invalidated the vote in the capital.3. encouragement：n. 鼓励Friends gave me a great deal of encouragement.4. enthusiastic：adj. 热情的;热心的;狂热的Tom was very enthusiastic about the place.三.重点句型1. ①when引起了时间状语从句，这句话给实验者效应下定义，实验者的期望有时候会影响实验的结果。

托福TPO4口语task4题目 Reading Part:Nonverbal LanguagesNonverbal language refers to human emotional expressions without involvingverbal statements. Facial expressions and body moments are the two mostlyattributed types of nonverbal languages. It is generally believed that nonverballanguages function as the enhancement of emotional expressions when they consistwith verbal languages.Under the circumstances that nonverbal languages and verbal languagescontradict in the contents they express, nonverbal languages are more likely torelease people’s true emotions.托福TPO4口语task4题目 Listening Part:Now listen to part of a lecture on this topic in a psychology course.Professor (male) Last month, my favorite uncle paid me a surprise visit. Ihadn’t seen him in many years. The door bell rang, I opened the door and therewas uncle Pete. Now, I am sure when I saw him I said something like, “UnclePete, what a surprise! How nice to see you.” Anyway, my wife was standing nextto me, and according to her, I wasn’t really aware of this, my eyes got really wide and I broke into a huge big smile, she said I was really jumping up anddown like a little boy. Well, anyway, later that evening uncle Pete told me how very good he felt when he saw how happy I was to see him.But compared that with this: my daughter, she’s six, we were building a bird house together last week, and I was showing her how to use a hammer and a nail. And, of course, stupid me, I wasn ’t being very careful when I smashed my thumb with the hammer. Boy, it hurt! I almost felt like screaming, but I didn’t wantto upset my daughter, so I said, “Don’t worry, honey. It’s nothing.” Meanwhile, I was shaking my hand as if that would stop my thumb from hurting and my facewas contorted in pain.My voice was trembling, too. So, even though I told my daughter I was OK, Iam sure she didn’t believe me, because she kept asking me if I was OK.托福TPO4口语task4题目 Question:Explain how the examples from the professor’s lecture illustrate therelationship between verbal and nonverbal communication.托福TPO4口语task4答案解析：1.

托福TPO34独立写作题目原文：Do you agree or disagree with the following statement?Educating children is a more difficult task today than it was in the past because they spend so much time on cell phone, online games, and social networking networking Web Web site.Use specific reasons and examples to support your answer.托福TPO34独立写作满分范文：It is universally acknowledged that various technologies such as cell phone, online games, and social networking Web sites play a more important role on in education than before. In my opinion, I disagree with the statement that nowadays it is more difficult to educate children than in the past because children can take advantage of those high-technologies to enhance their study. First and foremost, compared to in the past, at present the cell phone can is enabled to create a good positive effect on children’s study. Thanks to various of advanced software on the cell phone, student find it not difficult to grasp the most scientific leaning methods. For instance, in the past, children learned the new words by the text book without audio format, which led to the children couldn’t speak the words with correct pronunciations pronunciations children’s children’s false pronunciations pronunciations or or even mute English ; while today, children can are allowed to study those new words by the cell phone and they can imitate the native speaker’s speaker’s voice voice through the audio format in the cell phone. As a result, more and more children children can can speak English fluently. fluently. From From this fact, we can learn that the cell phone makes educating children much easier and comprehensive than before. Furthermore, teaching children is easier than before by the way of the obvious benefit that playing online games which can cultivate children’s ability of cooperation cannot be ignored. Through competing and interacting with others in the online games which can be called as a miniature of society, children can experience a sense of cooperation and responsibility intangibly. For example, due to the limitation of real situation, children had few opportunities to practice the ability of cooperation before. Nevertheless, it is much easier today, since in an online game, children are assigned to different tasks. Only when they cooperate well, can they get final success. From this experience, children can have a sense of teamwork, which cannot be learned from the class. This example tells us Obviously be learned from the class. This example tells us Obviously，，in the modern society, children children have have have kinds kinds kinds of of of chances chances chances to to to practice practice practice their their their cooperation’s cooperation’s cooperation’s ability ability ability as as as a a a result result of internet , which is better for their education. Finally, contract to the past, today social networking can expend children’s horizon, which is also beneficial for their education. education. various various various information information information filling filling filling in in the web provides provides children children children with with more broaden world without stepping outside. For example, ten years ago, with limitedtechnology, only through travel can children learn different cultures and languages. However, it spent cost more money and more time; what’s more, children were too young to go for a trip by themselves. So it was not easy to come true. But today, children just need to sit in front of the computer and type some key words through Google, and then they can get plenty of information as they want immediately. In addition, Children can learn other countries’ culture and languages by watching the video online. Consequently, we can realize that social network Web site is a useful wayto educate children. In a nutshell, I strongly disagree with the statement. With the advanced technology like cell phone, online games, and social networking Web site it can facilitate children’s education and help them be successful easier more easily in their future.满分范文，希望对你有所帮助!!独立写作题目文本++满分范文，希望对你有所帮助以上是给大家整理的托福TPO34独立写作题目文本。
托福TPO阅读34文本及答案解析
托福TPO阅读34文本+答案解析Islamic Art and the BookThe arts of the Islamic book, such as calligraphy and decorative drawing, developed during A.D. 900 to 1500, and luxury books are some of the most characteristic examples of Islamic art produced in this period. This came about from two major developments: paper became common, replacing parchment as the major medium for writing, and rounded scripts were regularized and perfected so that they replaced the angular scripts of the previous period, which because of their angularity were uneven in height. Books became major vehicles for artistic expression, and the artists who produced them, notably calligraphers and painters, enjoyed high status, and their workshops were often sponsored by princes and their courts. Before A.D. 900, manuscripts of the Koran (the book containing the teachings of the Islamic religion) seem to have been the most common type of book produced and decorated, but after that date a wide range of books were produced for a broad spectrum of patrons. These continued to include, of course, manuscripts of the Koran, which every Muslim wanted to read, but scientific works, histories, romances, and epic and lyric poetry were also copied in fine handwriting and decorated with beautiful illustrations. Most were made for sale on the open market, and cities boasted special souks (markets) where books were bought and sold. The mosque of Marrakech in Morocco is known as the Kutubiyya, or Booksellers’ Mosque, after the adjacent market. Some of the most luxurious books were specific commissions made at the order of a particular prince and signed by the calligrapher and decorator.Papermaking had been introduced to the Islamic lands from China in the eighth century. It has been said that Chinese papermakers were among the prisoners captured in a battle fought near Samarqand between the Chinese and the Muslims in 751, and the technique of papermaking – in which cellulose pulp extracted from any of several plants is first suspended in water, caught on a fine screen, and then dried into flexible sheets – slowly spread westward. Within fifty years, the government in Baghdad was using paper for documents. Writing in ink on paper, unlike parchment, could not easily be erased, and therefore paper had the advantage that it was difficult to alter what was written on it. Papermaking spread quickly to Egypt – and eventually to Sicily and Spain – but it was several centuries before paper supplanted parchment for copies of the Koran, probably because of the conservative nature of religious art and its practitioners. In western Islamic lands, parchment continued to be used for manuscripts of the Koran throughout this period.The introduction of paper spurred a conceptual revolution whose consequences have barely been explored. Although paper was never as cheap as it has become today, it was far less expensive than parchment, and therefore more people could afford to buy books, Paper is thinner than parchment, so more pages could be enclosed within a single volume. At first, paper was made in relatively small sheets that were pasted together, but by the beginning of the fourteenth century, very large sheets – as much as a meter across – were available. These large sheets meant that calligraphers and artists had more space on which to work. Paintings became more complicated, giving the artist greater opportunities to depict space or emotion. The increased availability of paper, particularly after 1250, encouraged people to develop systems of representation, such as architectural plans and drawings. This in turnallowed the easy transfer of artistic ideas and motifs over great distances from one medium to another, and in a different scale in ways that had been difficult, if not impossible, in the previous period.Rounded styles of Arabic handwriting had long been used for correspondence and documents alongside the formal angular scripts used for inscriptions and manuscripts of the Koran. Around the year 900, Ibn Muqla, who was a secretary and vizier at the Abbasid court in Baghdad, developed a system of proportioned writing. He standardized the length of alif, the first letter of the Arabic alphabet, and then determined what the size and shape of all other letters should be, based on the alif. Eventually, six round forms of handwriting, composed of three pairs of big and little scripts known collectively as the Six Pens, became the standard repertory of every calligrapher.Para.1 The arts of the Islamic book, such as calligraphy and decorative drawing, developed during A.D. 900 to 1500, and luxury books are some of the most characteristic examples of Islamic art produced in this period.

These plants usually occur where ants are abundant, most in the tropics but some in temperate areas. Among those of northeastern North America are various plums, cherries, roses, hawthorns, poplars, and oaks. Like floral nectar, extrafloral nectar consists mainly of water with a high content of dissolved sugars and, in some plants, small amounts of amino acids. The extrafloral nectaries of some plants are known to attract ants andother insects, but the evolutionary history of most plants with these nectaries is unknown. Nevertheless, most ecologists believe that all extrafloral nectaries attract insects that will defend the plant.Ants are portably the most frequent and certainly the most persistent defenders ofplants. ¢Since the highly active worker ants require a great deal of energy, plants exploit this need by providing extrafloral nectar that supplies ants with abundant energy. ¢To return this favor, ants guard the nectaries, driving away or killing intruding insects that might compete with ants for nectar. ¢Many of these intruders are herbivorous and would eat the leaves of the plants. ¢Biologists once thought that secretion of extrafloral nectar has some purely internal physiological function, and that ants provide no benefit whatsoever to the plants that secrete it. This view and the opposing “protectionist” hypothesis that ants defend plants had been disputed for over a hundred years when, in 1910, a skeptical William Morton Wheeler commented on the controversy. He called for proof of the protectionist view: that visitations of the ants confer protection on the plants and that in the absence of the insects a much greater number would perish or fail to produce flowers or seeds than when the insects are present. That we now have an abundance of the proof that was called for was established when Barbara Bentley reviewed the relevant evidence in 1977, and since then many more observations and experiments have provided still further proof that ants benefit plants.One example shows how ants attracted to extrafloral nectaries protect morning glories against attacking insects. The principal insect enemies of the North American morning glory feed mainly on its flowers or fruits rather than its leaves. Grasshoppers feeding on flowers indirectly block pollination and the production of seeds by destroying the corolla or the stigma, which receives the pollen grains and on which the pollen germinates. Without their colorful corolla, flowers do not attract pollinators and are not fertilized. An adult grasshopper can consume a large corolla, about 2.5 inches long, in an hour. Caterpillars and seed beetles affect seed production directly. Caterpillars devour the ovaries, where the seeds are produced, and seed beetle larvae eat seeds as they burrow in developing fruits.Extrafloral nectaries at the base of each sepal attract several kinds of insects, but 96 percent of them are ants, several different species of them. When buds are still small, less than a quarter of an inch long, the sepal nectaries are already present and producing nectar. They continue to do so as the flower develops and while the fruit matures. Observations leave little doubt that ants protect morning glory flowers and fruits from the combined enemy force of grasshoppers, caterpillars, and seed beetles. Bentley compares the seed production of six plants that grew where there were no ants with that of seventeen plants that were occupied by ants. Unprotected plants bore only 45 seeds per plant, but plants occupied by ants bore 211 seeds per plant. Although ants are not big enough to kill or seriously injure grasshoppers, they drive them away by nipping at their feet. Seed beetles are more vulnerable because they are much smaller than grasshoppers. The ants prey on the adult beetles, disturb females as they lay their eggs on developing fruits, and eat many of the eggs they do manage to lay.Para.1 Many plants – one or more species of at least 68 different families – can secrete nectar even when they have no blossoms, because they bear extrafloral nectaries (structures that produce nectar) on stems, leaves, leaf stems, or other structures.

To say that ants are “persistent” defenders of plants means thatA) they defend plants against a wide variety of threatsB) they continue to defend plants for as long as the plants are threatenedC) they are successful defenders of plantsD) they are easily observable defenders of plants3. What can be inferred from paragraph 2 about the ants that are attracted to the extrafloral nectaries?A) They do not eat the leaves of the plants that produce extrafloral nectar.B) They live almost entirely on extrafloral nectar.C) They spend most of their energy guarding extrafloral nectaries.D) They frequently fight among themselves over extrafloral nectar.Para.3 Biologists once thought that secretion of extrafloral nectar has some purely internal physiological function, and that ants provide no benefit whatsoever to the plants that secrete it.

The word “skeptical” in the passage is closest in meaning toA) curiousB) doubtfulC) open-mindedD) practical6. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.A) We now have ample proof that ants benefit plants.B) Barbara Bentley has called for additional proof that ants benefit plants.C) In 1977 Barbara Bentley conducted research that proved that all prior studies were wrong.D) Proof that ants benefit plants will require many more observations and experiments.Para.4 One example shows how ants attracted to extrafloral nectaries protect morning glories against attacking insects.

What role does paragraph 5 play in the passage?A) It offers various kinds of evidence for the protectionist view.B) It presents the study that first proved that ants benefit plants.C) It explains how insects find sources of nectar.D) It presents information that partly contradicts the protectionist view.10. The word “vulnerable” in the passage is closest in meaning toA) numerousB) harmfulC) open to attackD) difficult to locate11. According to paragraph 5, what did Bentley’s comparative study show?A) Many more plants grew in places where ants were present than where they were absent.B) The ants preferred plants with low seed production to plants with high seed production.C) The plants occupied by ants produced many more seeds than those that were not occupied by ants.D) The plants that grew in places without ants were much smaller and weaker than those that grew in places where ants were present.12. According to paragraph 5, ants defend morning glory plants from seed beetles in each of the following ways EXCEPTA) driving adult beetles off the plants by nipping at their feetB) catching and eating adult beetlesC) eating beetle eggs they find on developing fruitsD) making it difficult for beetles to lay eggs on developing fruits13. Look at the four squares 【】that indicate where the following sentence could be added to the passage. Sometimes they capture the insects to feed their protein-hungry larvae.Where does the sentence best fit?Ants are portably the most frequent and certainly the most persistent defenders of plants. 【】Since the highly active worker ants require a great deal of energy, plants exploit this need by providing extrafloral nectar that supplies ants with abundant energy. 【】To return this favor, ants guard the nectaries, driving away or killing intruding insects that might compete with ants for nectar. 【】Many of these intruders are herbivorous and would eat the leaves of the plants. 【】14. Prose SummaryMany plants have extrafloral nectaries that produce nectar even during periods in which the plant is not flowering. Answer ChoicesA) Evolutionary history shows that plants that produce extrafloral nectar originated in the tropics.B) Extrafloral nectar has a higher concentration of sugar than floral nectar and is more attractive to ants and other insects.C) The protectionist hypothesis is that extrafloral nextar attracts ants, and that the ants, in order to preserve this energy-rich food source, attack insects that might harm the plant.D) Evidence accumulated during the twentieth century proved that ants provide significant benefits for plants with extrafloral nectaries.E) Research has shown that American morning glory plants that are protected by ants produce significantly more seeds than morning glory plants that are not protected by ants.F) Ants generally ignore small insects, but they will eat the adults of large insect species as well as their eggs and larvae.The Development of Steam PowerBy the eighteenth century, Britain was experiencing a severe shortage of energy. Because of the growth of population, most of the great forests of medieval Britain hadlong ago been replaced by fields of grain and hay.。

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!。

ReadingA huge marine mammal known as Steller’s sea cow once lived in the watersaround Bering Island off the coast of Siberia. It was described in 1741 by GeorgW. Steller, a naturalist who was among the first European to see one. In 1768the animal became extinct. The reasons for the extinction are not clear. Hereare three theories about the main cause of the extinction.First, the sea cows may have been overhunted by groups of native Siberianpeople. If this theory is correct, then the sea cow population would haveoriginally been quite large, but hundreds of years off too much hunting by thenative people diminished the number of sea cows. Sea cows were a good source offood in a harsh environment, so overhunting by native people could have been themain cause of extinction.Second, the sea cow population may have become extinct because ofecosystems disturbances that caused a decline in their main source of food, kelp(a type of sea plant). Kelp populations respond negatively to a number ofecological changes. It is possible that ecological changes near Bering islandsome time before 1768 caused a decrease of the kelp that the sea cows dependon.Third, the main cause of extinction of the sea cows could have beenEuropean fur traders who came to the island after 1741. It is recorded that thefur traders caught the last sea cow in 1768. It thus seems reasonable to believethat hunting by European fur traders, who possessed weapons that allowed them toquickly kill a large number of the animals, was the main cause of the sea cow’sextinction.托福TPO34独立写作题目Do you agree or disagree with the following statement?Educating children is a more difficult task today than it was in the pastbecause they spend so much time on cell phone, online games, and socialnetworking Web site.Use specific reasons and examples to support your answer.，。

Theacademic dean, James Maxwell, commented, “The university is aware of the academic problems that many first-year students face when making the transition from high school to college.” The new tut oring program, he said, is designed to assist first-year students who want or need additional support with their academic course work.

Social psychologists refer to this tendency as the familiarity principle. Given a choice between two similar items, one they have experienced before and another that is new,most people will choose the familiar item. This principle operates even when people are not conscious of their previous experience with an item. Once people have been exposed to an item – even if they do not recall having been exposed to it – they will tend to prefer that item over other items to which they have not been previously exposed.听力原文Now listen to part of a lecture on this topic in a Psychology class.Some researchers did an experiment related to this. What they did was they assembled a group of subjects, a group of students, and they showed these students a series of geometrical shapes. These were very distinctive shapes, a little unusual, not the kind of shapes students often see. But they only showed the students the shapes for a very short period of time, about a second. They also lowered the light in the room to make it even more difficult for the students to see the shapes. So the shapes were there for a split second in dim light and then they were gone.In the next step of the experiment, the researchers again showed the students some shapes, but this time they gave the students a longer time to look at them. And this time they showed the images in pairs, two at a time. In each pair, one shape was a shape the students had already seen for just a split second in dim light. And the other was some other shape that hadn’t been shown to them before. After presenting each pair, the researchers asked the students to say which of the two shapes they liked better.Most of the time, the students preferred the shape they’d already seen earlier in the experiment. Now, if you asked them if they’d already seen that shape, they probably wouldn’t know for sure. But that didn’t matter. They still tended to prefer the sha pes they’d already seen.题目分析阅读✓The familiarity principle: 人们会更偏向他们已经见过的东西，即使他们并没有意识自己以前见过这个东西。

Islamic Art and the BookThe arts of the Islamic book, such as calligraphy and decorative drawing,developed during A.D. 900 to 1500, and luxury books are some of the mostcharacteristic examples of Islamic art produced in this period. This came aboutfrom two major developments: paper became common, replacing parchment as themajor medium for writing, and rounded scripts were regularized and perfected sothat they replaced the angular scripts of the previous period, which because oftheir angularity were uneven in height. Books became major vehicles for artisticexpression, and the artists who produced them, notably calligraphers andpainters, enjoyed high status, and their workshops were often sponsored byprinces and their courts. Before A.D. 900, manuscripts of the Koran (the bookcontaining the teachings of the Islamic religion) seem to have been the mostcommon type of book produced and decorated, but after that date a wide range ofbooks were produced for a broad spectrum of patrons. These continued to include,of course, manuscripts of the Koran, which every Muslim wanted to read, butscientific works, histories, romances, and epic and lyric poetry were alsocopied in fine handwriting and decorated with beautiful illustrations. Most weremade for sale on the open market, and cities boasted special souks (markets)where books were bought and sold. The mosque of Marrakech in Morocco is known asthe Kutubiyya, or Booksellers’ Mosque, after the adjacent market. Some of themost luxurious books were specific commissions made at the order of a particularprince and signed by the calligrapher and decorator.Papermaking had been introduced to the Islamic lands from China in theeighth century. It has been said that Chinese papermakers were among the prisoners captured in a battle fought near Samarqand between the Chinese and the Muslims in 751, and the technique of papermaking – in which cellulose pulp extracted from any of several plants is first suspended in water, caught on a fine screen, and then dried into flexible sheets – slowly spread westward. Within fifty years, the government in Baghdad was using paper for documents. Writing in ink on paper, unlike parchment, could not easily be erased, and therefore paper had the advantage that it was difficult to alter what was written on it. Papermaking spread quickly to Egypt – and eventually to Sicily and Spain – but it was several centuries before paper supplanted parchment for copies of the Koran, probably because of the conservative nature of religious art and its practitioners. In western Islamic lands, parchment continued to be used for manuscripts of the Koran throughout this period.The introduction of paper spurred a conceptual revolution whoseconsequences have barely been explored. Although paper was never as cheap as it has become today, it was far less expensive than parchment, and therefore more people could afford to buy books, Paper is thinner than parchment, so more pages could be enclosed within a single volume. At first, paper was made in relatively small sheets that were pasted together, but by the beginning of the fourteenth century, very large sheets – as much as a meter across – were available. These large sheets meant that calligraphers and artists had more space on which to work. Paintings became more complicated, giving the artist greater opportunities to depict space or emotion. The increased availability of paper, particularly。

托福TPO35口语Task4阅读文本： Integrated Farming Many farmers keep animals and raise crops at the same time. While some farmers treat the cultivation of their animals and plants as two separate activities, others integrate the two so that they work together. This is called integrated farming. Integrated farming uses the natural behavior of animals in a way that helps to keep both animals and crops healthy and thriving. By integrating a particular animal with a specific crop, farmers create a system in which both animals and plants provide for each other’s needs. 托福TPO35口语Task4听力文本： Now listen to part of the lecture from an environmental science class. Okay, so an example of this is when chickens are used to prepare a field for planting. Farmers who do this have a special kind of little house that they keep their chickens in. This little house has four walls and a roof but it doesn't have any floor. And it has wheels attached to it so it can easily be moved from one location to another. So farmers move this little house to a field where something is going to be planted. Say, bean plants. And then the chickens are placed inside the house, now remember there is no floor in this house and what the chickens do is they walk around inside the house and peck up the soil and eat any weeds or wild plants that they find. And then when the chickens are done eating the weeds in that location, the farmers move the house to the next section of the field. And again the chickens peck up the soil and eat the weeds. So the chickens get to eat a lot of weeds which are good for them. Now this activity is also good for the bean plants that'll be growing in the field, because when the chickens eat the weeds they're improving the quality of the soil. Thanks to the chickens when the bean plants start to grow there won't be any weeds there to compete with them for crucial resources, like sunlight and water. 托福TPO35口语Task4题目： Explain how the example from the lecture illustrate the concept of integrated farming. 托福TPO35口语Task4满分范文： Integrated farming means farmers treat the cultivation of the animals and the plants together in order to create a system in which both animals and plants providefor each other's needs. The professor illustrates the concept of integrated farming by using an example of farmers using chickens to help grow bean plants. In the example, the farmers move a little house that has no floor to some field preparing for growing bean plants. The farmers put the chicken in the little house and the chickens peck and eat up the weeds or plants in the soil, and when the chickens are done eating, the farmers will move to other places. According to the professor, this system is good for both the chickens and the bean plants because the chickens have enough weeds to feed and the quality of the field for the bean plants is improved since there will be no more competing weeds for crucial resources against the bean plants. 以上是给大家整理的托福TPO35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!。

托福TPO33口语Task4阅读文本： Carrying Capacity An animal species needs to have enough resources, like food and water, to survive in any given environment. However, because resources are limited, only a certain number of animals of a particular species are able to survive in a given habitat. The greatest number a habitat can support is known as the carrying capacity. If nothing happens to disrupt or unbalance the relationship between the animal and its habitat, the carrying capacity will remain stable. However, a carrying capacity is not fixed. If there is a significant disruption, such as an environmental event that alters the amount of available resources in the habitat, the carrying capacity will change. 托福TPO33口语Task4听力文本： Now listen to part of a lecture in a biology class. ProfessorOK, so let's talk about what happened to a certain type of insect, a moth, a red-and-black moth that lives in Europe. These moths eat a plant called Ragwort and they live in fields where the Ragwort plants grow. Now, there was a group of moth that lives in one of these fields and, for many years, there was a lot of Ragwort growing there. So the moth had plenty to eat and the total number of moth in the field stayed pretty much the same. But then one year it rained a lot less than usual and the Ragwort didn't grow as well. The result was that the moth didn't get enough to eat and many didn't survive but even the ones that did survive didn't lay as many eggs as before. So that year the moth population in the field was quite a bit smaller. The next year, though, the amount of rainfall returned to normal and again many more Ragwort plants grew and, once again, there was a lot available for the moth to eat. So that yearthe moth population increased and the female moth laid many more eggs than the year before. And now, after all that rainfall and plant growth, there were just as many moth in the Ragwort field as there were before." " 托福TPO33口语Task4题目： Explain the concept of carrying capacity using the example of the moth and Ragwort. 托福TPO33口语Task4满分范文： The maximum number of species that a given habitat can support is called carrying capacity. According to the professor, there's a kind of red and black moths that eata plant called ragworts, and they live in the ragworts field. When there was sufficient ragworts for the moths, the moths' population remained stable over the years, and that stable number of moths' was the field's carrying capacity. However, one year, the balance was disrupted as it rained much less than usual and the production of ragworts decreased, so the moth's population declined because of lack of food and female moths' inability to lay eggs. Then the next year, when the rainfall returned to its previous level, ragworts grew back, and accordingly the number of moths increased and female moths laid more eggs, and soon there were as many moths as the year before the drought, which suggests that carrying capacity of a given habitat changes with the disruption.

And well…it’s an old book, and there were two copies on the shelf justnow, so I was wondering if I could buy one. I was talking to this guy the otherday, and he said the library sold books on occasion. Is that right?LibrarianHe is probably talking about our annual book sale. We have one everyspring.StudentOK. How do you decide which books to sell? Are they duplicates?LibrarianA lot are duplicates. If we have more than one copy of a title and ithasn’t been checked out in a few years, in that case it might end up at thesale.StudentI’ve actually tried to find this book online but no luck so far. I wasreally hoping to buy it.LibrarianWell, that particular book…well, it probably won’t be up for sale this year. Most books in the sale come from off-site storage.StudentOff-site storage?LibrarianThat’s where we keep books that haven’t been used for several years. They are still in the catalog, which means they can be checked out if you fill out a form. It takes maybe a day or two to retrieve one of them.StudentI see.LibrarianAnd then before we decide to include a book in the sale, we review its circulation history again, which can take a while. We’ve got a lot of books in storage.StudentSo it’s basically the unpopular books that get put up for sale then?LibrarianWell, that…plus the main thing is to make sure students have access to the information in the books.

托福TPO34独立写作题目原文： Do you agree or disagree with the following statement? Educating children is a more difficult task today than it was in the past because they spend so much time on cell phone, online games, and social networking Web site. Use specific reasons and examples to support your answer. 托福TPO34独立写作满分范文： It is universally acknowledged that various technologies such as cell phone, online games, and social networking Web sites play a more important role on in education than before. In my opinion, I disagree with the statement that nowadays it is more difficult to educate children than in the past because children can take advantage of those high-technologies to enhance their study. First and foremost, compared to in the past, at present the cell phone can is enabled to create a good positive effect on children’s study. Thanks to various of advanced software on the cell phone, student find it not difficult to grasp the most scientific leaning methods. For instance, in the past, children learned the new words by the text book without audio format, which led to the children couldn’t speak the words with correct pronunciations children’s false pronunciations or even mute English ; while today, children can are allowed to study those new words by the cell phone and they can imitate the native speaker’s voice through the audio format in the cell phone. As a result, more and more children can speak English fluently. From this fact, we can learn that the cell phone makes educating children much easier and comprehensive than before. Furthermore, teaching children is easier than before by the way of the obvious benefit that playing online games which can cultivate children’s ability of cooperation cannot be ignored. Through competing and interacting with others in the online games which can be called as a miniature of society, children can experience a sense of cooperation and responsibility intangibly. For example, due to the limitation of real situation, children had few opportunities to practice the ability of cooperation before. Nevertheless, it is much easier today, since in an online game, children are assigned to different tasks. Only when they cooperate well, can they get final success. From this experience, children can have a sense of teamwork, which cannot be learned from the class. This example tells us Obviously，in the modern society, children have kinds of chances to practice their cooperation’s ability as a result of internet , which is better for their education. Finally, contract to the past, today social networking can expend children’s horizon, which is also beneficial for their education. various information filling in the web provides children with more broaden world without stepping outside. For example, ten years ago, with limitedtechnology, only through travel can children learn different cultures and languages. However, it spent cost more money and more time; what’s more, children were too young to go for a trip by themselves. So it was not easy to come true. But today, children just need to sit in front of the computer and type some key words through Google, and then they can get plenty of information as they want immediately. In addition, Children can learn other countries’ culture and languages by watching the video online. Consequently, we can realize that social network Web site is a useful way to educate children. In a nutshell, I strongly disagree with the statement. With the advanced technology like cell phone, online games, and social networking Web site it can facilitate children’s education and help them be successful easier more easily in their future. 以上是给大家整理的托福TPO34独立写作题目文本+满分范文，希望对你有所帮助!。

托福TPO32口语Task4阅读文本： Choice-Supportive Bias People often make decisions by considering the advantages and disadvantages of each option. However, after a person selects an option, there is a tendency for that person to exhibit the choice-supportive bias. After selecting an option, a person may begin to favor that option. Without being fully aware of it, people who exhibit this bias tend to focus on and remember only the advantages of the option they selected. As time passes, they will overlook the option’s disadvantages, eventually even forgetting them. 托福TPO32口语Task4听力文本： Now listen to part of a lecture on this topic in a Psychology class. ProfessorOK, so an example of this from my own life: five or six years ago, I was helping a friend of mine decide on a house to buy. He had been in the market to buy a house and he had it narrowed down to this one house that he was interested in. What he really liked about this house was it had an excellent location. It was in a great place that was actually in the same part of town where he was working right up the street from his job. So he wouldn't have far to drive to get to work which he really liked. However, the downside of this house was that it was smaller than what he was hoping to buy. He wanted to buy sort of a big house and this house just wasn't that big. So it was a tough decision. But my friend eventually did decide to buy the house. And a few years after he made the purchase, I remember, we were talking about the decision and why he decided to buy the house. He told me, well, of course, it was because of the house’s location. He told me how happy he was with the fact it was so close to his work, how great it was only few minutes from his job. I said, “Yes, but, what about its size? Do you still think the house is kind of small?”And he looked at me kind of surprised, “Small? What do you mean small?” Like he didn’t know what I was talking about. The house’s size, a couple of years after buying it, just didn’t seem to be on his mind anymore. 托福TPO32口语Task4题目： Explain how the example from the professor’s lecture illustrate the choice-supportive bias. 托福TPO32口语Task4满分范文： The tendency that people are likely to neglect the disadvantages of their choice after they've made it is called choice-supportive bias. For example，the professor's friend wanted to buy a house several years ago, and he found a house located in the same part of the town where he worked. But the house was not so perfect to his friend because it was smaller than what he wanted to buy. So it was a tough decision. Anyway his friend finally bought the house for its location. A few years later, when the professor visited him, they talked about the decision and he told the professor how happily he bought a house so close to his workplace. But when the professor asked him about the size problem, he responded as if he hadn't even realized that, because he was choice-supportive biased.

It was described in 1741 by Georg W. Steller, a naturalist who was among the first European to see one. In 1768 the animal became extinct. The reasons for the extinction are not clear. Here are three theories about the main cause of the extinction. First, the sea cows may have been overhunted by groups of native Siberian people. If this theory is correct, then the sea cow population would have originally been quite large, but hundreds of years off too much hunting by the native people diminished the number of sea cows. Sea cows were a good source of food in a harsh environment, so overhunting by native people could have been the main cause of extinction. Second, the sea cow population may have become extinct because of ecosystems disturbances that caused a decline in their main source of food, kelp (a type of sea plant). Kelp populations respond negatively to a number of ecological changes. It is possible that ecological changes near Bering island some time before 1768 caused a decrease of the kelp that the sea cows depend on. Third, the main cause of extinction of the sea cows could have been European fur traders who came to the island after 1741. It is recorded that the fur traders caught the last sea cow in 1768. It thus seems reasonable to believe that hunting by European fur traders, who possessed weapons that allowed them to quickly kill a large number of the animals, was the main cause of the sea cow¡¯s extinction.¡¡¡¡Íи£TPO34×ÛºÏд×÷ÌýÁ¦Ô-ÎÄÎı¾£º¡¡¡¡The truth is we don¡¯t know what the main cause of extinction of Steller¡¯s sea cow was. There are problems with each of the theories that you read about.First, the sea cows were massive creatures. They were up to nine meters long and could weigh over ten tons, just enormous. A couple of sea cows could feed a small Siberian village for months. And the population of the native Siberian people wasn¡¯t very large. So while the Siberians certainly did hunt the sea cows, they didn¡¯t need to hunt a lot of them. So it¡¯s unlikely they were the ones who brought the sea cows to the point of extinction.Second, about a hypothetical decrease in kelp caused by ecological disturbances, well, if something severe really happened in the ecosystem near Bering Island sometime before 1768, it would have affected not just the kelp but also other parts of the ecosystem. For example, it would have caused the decline in other marine animals like whales. But fishing ships in the area did not report a whale decline. Since there is no indication of broader ecosystem problems, the kelp was probably growing just fine and the sea cows did not experience food shortage.Third, it might seem like the European traders were responsible because the sea cows became extinct soon after the Europeans arrived. But, actually, by the time that the Europeans arrived, the sea cow population was already quite small. We have evidence that thesea cow population was at its largest hundreds of years before the 1700s. So something was causing a serious and on-going decrease in the sea cow population long before the Europeans arrived in the Bering Island area. Whatever this something was, it shouldbe considered the main cause of the extinction, not the European traders who were just the last to arrive.¡¡¡¡Íи£TPO34×ÛºÏд×÷Âú·Ö·¶ÎÄ1£º¡¡¡¡According to the reading passage, the author claims that there are three theories elaborating the reasons for declineof sea cows. However, the lecturer entirely challenges these theories. First of all, in the reading passage theauthor believes that overhunting by Sibrian for food is the major factor forthe decrease of sea cows.In contrast, the lecturer opposes this view and maintains that sea cows, a kind of animal with approximately ten tons, are tooenormous for people to eat, and another contributor refuting the view in thereading is that the population of people was not substantial at that time,which do not have the capacity to kill the majority of sea cows. Furthermore, contrary to the statement inthe reading passage that the extinction of sea cows is due to the fact that it is the quantity of Kelp, regardedas the food resource of sea cows, decreased by the destruction of ecosystem, the lecturer asserts that Kelp also is thefood resource for whales, which means if the population of Kelp decreases, thenumber of whales will decline as sea cows do. But there is no report about the decline of them. Eventually, the lecturer casts doubton thepoint made by the author that the extinction of sea cows may be caused by Europeanfur traders, and he proposes that actually when European fur traders firstly arrived there, the population of sea cows had already been small;therefore, there must be other fatal events causing the decrease in the population of sea cows before fur traders being there.¡¡¡¡Íи£TPO34×ÛºÏд×÷Âú·Ö·¶ÎÄ2£º¡¡¡¡The reading passage proposes three possible theories about why the gigantic Steller's sea cow became extinct. However, the professor in the listening states thatall of the theories have problems, and he has proposes sufficient evidence to refute these three hypotheses. First of all, the first theory stated in the reading article claims that these sea cows became extinct because of the hunting by the native peoplein the Siberia since they were a good source of food in a harsh environment. However, the lecturer in the listening contradicts the theory by contending that these animals were extremely massive: nine meters in length and ten tons in weight. Therefore, even though the Siberian people did really hunt them for food, these people only neededa few of them, which could provide the food for months. This negates the first theory. Next, the second theory in the passage maintains that they became extinct becauseof the ecology disturbances, which led to the main source of food, Kelp, for the sea cows diminished. On the contrary, the speaker in the listening seriously challenges the theory by pointing out that if the ecosystem really had some disturbances, there。

For example, professor taught his daughter how to wash her hands. He divided this complex behavior into 5 steps, and taught his daughter one step at a time. He first showed his daughter step 1 and practiced it with her for a couple of days. When she has mastered this action, he showed her step 2 and let her practice both steps for another few days until she can do both by herself. Then he added the third step after, and also let her practice for a while until she can do them all. For the last two steps, he did the same thing as the previous three steps. Finally she could finish the hand washing all by herself.tpo34口语task4范文第5篇范文：In the lecture, the professor mainly talked about the theory aboutagonistic behavior. To reinforce the theory, the professor gave an example about two rattlesnakes in his speech. In the example, scientists saw two rattlesnakes had found the same hole and both of them wanted to eat the food there. And what happened was the two rattlesnakes faced each other and made themselves as tall as possible. And then they began pushing each other and trying to control one another. But in this process, neither of those two rattlesnakes was trying to hurt each other. And the snake which could have easily bitten the other one, it didn’t, and let it go.

托福TPO40口语Task4阅读文本： Agonistic Behavior Within certain animal species, conflicts sometimes arise over resources such as territory or food. To resolve these conflicts, two animals of the same species may engage in agonistic behavior. With this type of aggressive behavior, the animals participate in a physical competition that demonstrates which animal is more powerful. While each animal attempts to prove its strength in the competition, it typically does so without harming the other animal. Once the winner is established, that animal gains access to the desired resources, while the weaker animal surrenders and leaves the area. 托福TPO40口语Task4听力文本： Now listen to part of a lecture in a biology class. I know some scientists who were observing snakes in the wild. And they witnessed an encounter of this sort between two rattlesnakes. Uh...as you may know, rattlesnakes eat various kinds of small animals. Small animals that live underground, in burrows, in little holes in the ground. And what these scientists saw was these two rattlesnakes had found the same hole and both wanted to eat whatever food was in that hole. So what happened was: The two rattlesnakes faced each other and then they lifted their bodies into an upright position and made themselves as tall as possible. And then they started pushing each other, kind of wrestling with one another, each snake trying to gain control of the other snake. And what's interesting is that during all these pushing and shoving and maneuvering, neither snake ever tried to bite the other snake. Neither snake ever tried to injure the other snake. So...after this went on for a while, one of the snakes finally gained control of the other snake, pushed it to the ground and held it there. At this point, the snake that was on top could have easily bitten the other snake. But it didn't. Instead, it just released the other snake, just let it go. The snake that had lost just slithered away, and the snake that had won went down into the hole to look for food. 托福TPO40口语Task4题目： Explain how the example in the lecture illustrates agonistic behavior. 托福TPO40口语Task4满分范文： In the lecture, the professor mainly talked about the theory about agonistic behavior.

托福TPO34口语Task4阅读文本：
The Familiarity Principle
People tend to develop a preference for this they have previously encountered, things they are familiar with. Social psychologists refer to this tendency as the familiarity principle. Given a choice between two similar items, one they have experienced before and another that is new, most people will choose the familiar item. This principle operates even when people are not conscious of their previous experience with an item. Once people have been exposed to an item – even if they do not recall having been exposed to it – they will tend to prefer that item over other items to which they have not been previously exposed.
托福TPO34口语Task4听力文本：
Professor：Some researchers did an experiment related to this. What they did was they assembled a group of subjects, a group of students, and they showed these students a series of geometrical shapes. These were very distinctive shapes, a little unusual, not the kind of shapes students often see. But they only showed the students the shapes for a very short period of time, about a second. They also lowered the light in the room to make it even more difficult for the students to see the shapes. So the shapes were there for a split second in dim light and then they were gone.In the next step of the experiment, the researchers again showed the students some shapes, but this time they gave the students a longer time to look at them. And this time they showed the images in pairs, two at a time. In each pair, one shape was a shape the students had already seen for just a split second in dim light. And the other was some other shape that hadn't been shown to them before. After presenting each pair, the researchers asked the students to say which of the two shapes they liked better. Most of the time, the students preferred the shape they’d already seen earlier in the experiment. Now, if you asked them if they’d already seen that shape, they probably wouldn’t know for sure. But that didn’t matter. They still tended to prefer the shapes they’d already seen.

托福TPO34口语Task4满分范文：
Familiarity principle is the tendency that people usually prefer things that
they're familiar with to new ones, even when they're unconscious of their exposure to the item. And the professor illustrates this with an experiment. In the experiment, a group of students were first shown several geometrical shapes, which were really uncommon, for a very short period of time in dim light so that they hardly perceived the objects consciously. Then the researchers showed the students a pair of shapes, and allowed them longer time to look at those shapes, one of which was the shape they had seen in dim light in a flash, while the other, a new one. After that the researchers asked these groups of students which shape they preferred because of familiarity principle, they tended to prefer the one they had already seen to the one they hadn't seen even though they were uncertain whether they'd seen the shapes.
