TPO23Lecture l-Archaeology(Antikythera(Mechanism)Professor：I was talking to one of my colleagues in the physics department the other day,and we ended up discussing how one discovery can change everything.My colleague mentioned how the theory of relativity completely changed the field of physics.At any rates,that conversation got me thinking about archaeological finds that really changed our understanding of ancient civilizations.So I want to talk about the discovery of the Antikythera Mechanism.The Antikythera Mechanism was found a hundred years ago, under water in an ancient Greek shipwreck in the Mediterranean Sea.It was in extremely poor condition and in many corroded pieces.But once we figured out what it was and reconstructed it.Well,I simply don't have the words to convey how extraordinary this find was.The Antikythera Mechanism is a relatively small device,roughly the size of a shoebox, made of gears fitted inside a wooden case.In its original state,there were rotating dials and other indicators on the top,with letters and drawings showing the Sun,the phases of the moon and different constellations.Inside the box,bronze gears would have rotated the displays.The displays,uh,the indicators of the Antikythera Mechanism,would then movedto show the motion of the Sun and moon relative to the planets and stars.The device could be used to tell the different phases of the moon and much more.Well,scientists have recently analyzed the inscriptions on the mechanism andre-examine the other cargo in the ship wreck,and the evidence makes an absolute case that this device dates back to ancient Greece somewhere between150and100B.C.E.What makes that so fascinating is that before we found the Antikythera Mechanism,the earliest device we had that could track the Sun and moon like this was invented over1,000years later.So when this was first found,people literally would not believe it.Some of my colleagues insisted it had to have been made well after100B.C.E.But this physical evidence was conclusive.It was that old.Of course part of what made this find so unusual is that the Antikythera Mechanism is constructed of bronze.Now,it is not that bronze was all that rare in Greece then,it is just that bronze was valuable and could easily be recycled.It would have been relatively easy for a person with knowledge of metals to melt down bronze objects and forge them into?well,say,coins.Bronze was used to made money back then. Or mold the bronze into anything else of value for that matter.We are very fortunate that the device ended up under water,because otherwise it probably would have ended up recycled into?who knows what.Now,it was a challenge to figure out the Antikythera Mechanism.It spent over2,000years at the bottom of the sea before it was discovered. And even after it was discovered,it was still a number of years before we really understood what it was.You see,the mechanism had corroded underwater,and many of the gears were stuck together in a mass.Cleaning it was only partly successful.We could only get agood look at the structure of the gears after gamma-rays were used to see inside,very similar to the way X-rays are used to see your bones.Now,once we got a good look inside, we saw a really complex device.The many gears not only moved in a way that could indicate the phases of the moon.The Antikythera Mechanism also tracked both the lunar year and the solar year.Additionally,the gears also moved to match the motions of the planet and predicted eclipses.But one thing that is particularly notable is that the mechanism was so precise that it even took into account a particular irregularity in the moon's orbit,which requires some very complex math to replicate in mechanical device.You could say that the Antikythera Mechanism was a very precise calendar,which stands to reasons calendars were very important to ancient peoples.Religious festivals had to be held at the right time of year,crops needed to be planted at the right time as well. And let's not forget that eclipses in planetary motions had important symbolic meanings.教授：有一天我跟物理系的一位同事聊天，聊到一个发现有可能会改变所有的事情。

TPO23TPO 23Task 3：Now listen to two students discussing the article.(man) Hey, what do you think of this?(woman) You mean the editors’ decision?(man) Right.(woman) I think they are right. It’s the thing to do.(man) Really? Why?(woman) Well, hardly anyone reads that section.(man) You don’t think so?(woman) Not really, I mean, they only cover stories and most people already know about them before they even get around to reading the campus paper.(man) True, if you get the local paper, or use the internet, you already know the major stories.(woman) Exactly, and the coverage’s better. I think we should just stick with campus news and stuff.(man) So do you think what they’re gonna replace with is better?(woman) Definitely, right now, how do you learn about what’s happening on campus? (man) Mostly from posters in different buildings or in the student center.(woman) Right, th e information is everywhere but it’s hard to keep track of it. I see stuff posted but then I forget about it half the time.(man) So you’re saying that with this new section?(woman) You could just cut it out from the newspaper and carry it around and check it anytime and know what’s taking place when and where.The woman expresses her opinion about the plan announced in the article. Briefly summarize the plan. Then state her opinion about the plan and explain the reasons she gives for holding that opinion.Task 4：Now listen to part of a lecture in a sociology class on this topic.(male professor)I have an example from my own life that illustrates this. When I first began my university studies, I became friends with a bunch of art students. They were older and fun and very creative and I thought they were really cool. And they all liked to dress really casually, in T-shirts and jeans and sneakers. That's what they wore all the time, to class, to the library, to dinner, everywhere, T-shirts and jeans and sneakers.So that’s what I started wearing, too . An d I fit right in, and I felt really cool.But then I graduated, moved to Chicago, and got a job. And I started working with some really bright, young people who'd already been working in the company for a few years, who were already handling major responsibilities for the company, really impressive. And sometimes some of us would get together on the weekend, maybe for a concert or a baseball game or something. And at first, I just wear a T-shirt and jeans and sneakers. That was, you know, how I was used to dressing. But I soon noticed that my co-workers preferred to dress up a little bit. The men would wear a nice pair of pants, uh, button-up shirt. The women might wear a fashionable dress and some nice shoes. They dress in clothes a lot nicer than what I was used to wearing.And I started thinking, you know, that looks really classy, really sharp. And so I started to dress the same way they did, you know, nicer, a little more formal. And, I don’t know, somehow my T-shirts and jeans and sneakers didn’t se em as cool anymore.Using the example from the lecture, explain how people's behavior is affected by reference groups.Task 5：Listen to a conversation between two students.(woman) How’s it going, Mike?(man) OK, I’m just trying to figure out wh at to do about this new bus schedule. (woman) New bus schedule?(man) Yeah, I take a bus from campus to my job downtown. I work there Tuesday afternoons, but the bus schedule changed. The bus I was taking is leaving earlier now and I can’t get to it in t ime because I’ve got chemistry class then.(woman) Huh, yeah, they did change the bus schedule sometimes. It’s inconvenient. So what are you gonna do?(man) Well, I talked to my boss and she said I could change my work hours and work at night instead. I’d start late in the afternoon and work till around midnight. And there is a bus that’ll get me down on time.(woman) That sounds good. So you could just take a later bus to your job.(man) Yeah, the only thing is if I worked late at night. I’ll be re ally tired and I have class early the next morning.(woman) Yeah, but do you have any other choice?(man) Well, yeah, another option is just to ride my bike to work after chemistry. I’ll be able to get to work on time so I could keep my same hours. It’s not that far. It takes about 15 minutes.(woman) Hmm, that might be nice plus you get some exercise but it’ll be a bit uncomfortable riding your bike on days when there’s bad weather.(man) Yeah, I’ll have to think about it.Briefly summarize the problem the speakers are discussing. Then state which solution you would recommend. Explain the reasons for your recommendation.Task 6：Listen to part of a lecture in a biology class.(female professor)Now, plants, like animals, and like us for that matter, need nutrients, substances that provide nourishments, to survive, thrive and grow. We get our nutrients from the food we eat. Plants, though, most plants anyway, absorb their nutrients from the soil, right, through their root systems? OK, but th ere are plants that don’t get their nutrients from the soil. The places they grow the soil is bad. So they get their nutrients from insects instead, from trapping and digesting insects. They are called carnivorous plants.Carnivorous plants capture insects in different ways. They have different trapping mechanisms: active traps and passive traps. A plant with an active trap, a good example is the Venus flytrap. The Venus flytrap actually moves to capture its prey or parts of it anyway. Its leaves, it has special leaves that are hinged in the middle the two halves of the leaves open and close sort of like a mouth to catch insects. And on these leaves is a sweet nectar that attracts insects. Insects like the sweet stuff. And when they get lured in and land on the leaf, wham! The leaf springs shut. It’s an active trap. And the insect springs it so to speak. The leaf quickly closes to form a little cage, trapping the insect between the leaves. The Venus flytrap is then able to digest the insect and get its nutrients.But other carnivorous plants, their methods are passive. They don’t have any moving parts to trap things. They have passive traps, like the sundew plant. The sundew plant also produces a sweet nectar that attracts insects. Its leaves are full of little hairs that secrete sweet substance. But what happens when insects land on sundew's leaves to get the sweet nectar? Well, unfortunately for the insects, the hairs on the leaves also produce a super sticky glue-like substance. So an insect get stuck an d can’t fly away.It basically get glued there allowing the sundew to digest it and absorb nutrients.Using the example of the Venus flytrap and the sundew, describe two ways that carnivorous plants get their nutrients.。

TPO23 L ISTENING T EXT 5教授：我们已经讨论过海洋生物在水里如何寻找方向，它们如何航行，并且这带来了一个有趣的谜题，一个我保证你们都会感兴趣的谜题。

大家都喜欢海豚吧？那么，海豚实际上发出两种声音。

第一种通过喷水孔发出声音的发声法想必大家都已熟知。

而我们今天主要关注的是它们用于回声定位的短促的咔嚓声，由此它们可以探测周遭环境。

实践证明，这些声音是由海豚的装满空气的鼻液囊中发出的。

那个谜题是：那个咔嚓声是如何在水中传播的？这并不像想象中那样简单。

你看，介质的密度越大，声音传播速度也越快。

因此，声音在水中传播的速度比在空气中更快。

那么，声波又如何呢？好，现在有一束光波在一种介质中愉快地穿行，突然，它撞到了另一种不同的介质，接下来会发生什么呢？对，一部分能量将被反射回来，另一部分则将在第二种介质中传播。

接着呢？在接下来呢？如果这两种介质有着非常不同的密度，比如空气和水，那么大多数的能量都将被反射回来，只有很小的一部分会继续前行，即在新的介质中传播。

我的意思是，就想想当你潜在水里时，外面那些声响实际上传入你的耳朵里有多么小。

那么，海豚的咔嚓声是如何通过它的充满空气的鼻液囊传播进入海水的呢？因为我们已经知道鼻腔中的空气和海水的密度的不同，我们可以想象这些声音在海豚的脑中来回循环，这将不会让海豚好受。

如果它想要航行，它将需要传播那些声音，并且被一些前方的物体反弹。

已被证实，在海豚前额中鼻液囊的正前方，有一种叫做额隆的结构。

目前，额隆被看作是一种由脂肪组织构成的大的囊状袋。

并且，这个脂肪组织有一些相当有趣的声学的性能。

大多数在动物体内的脂肪都是用来储存能量的，但是在海豚体内并且仅仅在额隆以及下颌周围发现的这种脂肪，是非常不一样的，富含非常多的油脂。

并且，也展现出了十分不同的用途。

现在，克服空气和水的密度差异的方法是？如果你用和声波一样的速率前进，准确地与在某种水中的速度吻合。

这就是海洋生物学家发现的额隆。

Q1答案：C解析：以market demands做关键词定位至第二句，提到农业现代化，commercialized的作物和先进的agricultural technique使得产量升高，从而可以满足市场的需要，因此这些人满足市场需要的原因是作物的产量高，所以正确答案是C。

A和B都完全没提到，D错误，因为原文说的是从Baltic进口，不是满足Baltic的需要。

Q2答案：B解析：这个句子的大致结构是import使得价格下降，因此刺激需求，所以正确答案是B。

选项A的进口其他食物和C的primary goal原文都未提及，D的结构完全和原句不符合，错误。

Q3答案：A解析：apart from“除……之外还有”，所以正确答案是besides。

原文提到这个，不进行需要大量劳动力的grain production，也使得劳力和土地都被解放出来进行更productive的产业。

整句话在说不生产grain的一个优点，上一个题的长句子已经说了一个优点，因此这是在说另外一个优点，应该是“除了……还有……”，所以A是正确答案。

B“尽管”C“因此”D“而不是”都完全不合文意。

Q4答案：D解析：以urban consumers做关键词定位至倒数第二句，提到城市消费者需要奶制品，而奶制品比谷物价格贵得多，但这句只说了现象，没说结果，往下看。

提到高价使农民改善了牲畜饲养技术，所以正确答案是D。

A的shortage原文未提及，B的grain是原文说放弃的，C的high price不是农民收的。

Q5答案：D解析：consumption“消费，使用，吃掉”。

所以正确答案是D的utilization，原词来自consume。

原文提到蔬果通过水路运到城市里的市场中，蔬菜与水果的使用/消费不仅限于富人，富人运水果，存水果和卖水果都不合文意，前文提到以前只有富人能吃得起蔬果，所以正确答案是D。

Q6答案：B解析：此题可以采用排除法，A选项没有很好的关键词，暂时可以不管；B的flower 未提及，原文提到的不只是富人种蔬果，不是富人改种花，所以B与原文相反，选；C的city markets by water做关键词定位至最后一句，正确，不选；同时这句话也可以判断出D选项正确，不选；倒数第二句提到整个村子都种蔬果，也就是A说的commercial venture，A正确，不选。

托福TPO23听力Conversation2文本 Narrator: Listen to a conversation between a student and his English professor. Professor: Hi, Bob. How is it going? Are you enjoying the Introduction to Literature class? Bob: Yeah, it's great. Araby, that short story by James Joyce we read last week, it was awesome. Professor: I'm glad you like it. Most of Joyce's work is very complex. A lot of students say that he is hard to understand. Normally, you wouldn't tackle Joyce in an Intro class, but I'd like to give my first year students a taste of his style, his psychological approach to literature, because, mainly because it influenced other writers.I only wish we had more class time to discuss it. Bob: Me too. So why did you pick Araby instead of some other story? Professor: Well, um, first you should know that Araby is one of fifteen short stories by Joyce in a book called Dubliners. Uh, all the stories are related to one another, and they are set in the same time period. But Araby is the easiest one to follow. Though all the stories in the collection are written in stream of consciousness, which as you know, means they are told through the narrator's thought, through an inner monologue, as opposed to dialogue or an objective description of events. But Araby is easier because it's linear, the story unfold chronologically. Bob: Still, I wish we could read whole novels by Joyce and discussed them in class. Professor: That's what happens in my Master Writer Class. Bob: Master Writer Class? Professor: Yeah, I teach one on Joyce every spring. It's such a privilege, spending an entire term diving into a single body of work. And my students, they bring so much insight to the table that it's easy to forget who the professor is. Bob: Oh, wow. That could actually solve my dilemma, uh, what I originally wanted to ask you? Um, I am working on my schedule for next term, and I've got room for one more course, and I'd like to take more literature. Could I take your Master Writer Class on Joyce? Professor: I'm sorry. I should have mentioned. Uh, Master Writer is an advanced seminar. So students need to get a strong foundation in literary theory and criticism before I let them in the room. Bob: But I have gotten really good grades on all my paper so far, I'm sure I can keep up. Couldn't you make an exception? Professor: Your grades are excellent. But in our intro class, you are reviewing the basics, like plots, setting and character and getting your first real exposure to different literary styles. Bob: But why do I have to study different styles to understand Joyce's novels? Professor: There are a lot of little details involved in interpreting literature. And like with Joyce. His novels have very unique structures. The only way to appreciate how unique they are is by studying a variety of authors. Bob: Oh, OK. So could you suggest a different literature class then? Professor: Sure. There's doctor Clain's course on nineteenth-century novels. It's more focused than the class you're in now.But it will build on your current knowledge base and give you the background you need. That, plus a couple more foundational classes, and you will definitely be ready for my seminar. Bob: Sweet. Thanks. 托福TPO23听力Conversation2题目 1.Why does the man go to see the professor? A.

The word “surpass” in the passage is closest in meaning toA.remain belowB.be higher thanC.add toe close to3. According to paragraph 2, how soon heat from a warmed house reaches the outside air greatly affected byA.how well the house is heatedB.how well the house is insulatedC.how many adults live in the houseD.how much sunshine the house receives4. According to paragraph 3, each of the following contributes to making urban areas warmer than the surrounding countryside EXCEPTA.the fuel burned by motor vehiclesB.the capacity to store heat of the materialsused in building a cityC.the easy flow of heat into the ground in cityareas covered by vegetationD.the repeated reflection of solar radiation backand forth among buildings5. According to paragraph 3, why do materials in the countryside have a lower heat capacity than materials in cities do?A.In the countryside in the Sun is the onlyUrban ClimatesThe city is an extraordinary processor of mass and energy and has its own metabolism. A daily input of water, food, and energy of various kinds is matched by an output of sewage, solid waste, air pollutants, energy, and materials that have been transformed in some way. The quantities involved are enormous. Many aspects of this energy use affect the atmosphere of a city, particularly in the production of heat.In winter the heat produced by a city can equal or surpass the amount of heat available from the Sun. All the heat that warms a building eventually transfers to the surrounding air, a process that is quickest where houses are poorly insulated. But an automobile produces enough heat to warm an average house in winter, and if a house were perfectly insulated, one adult could also produce more than enough heat to warm it. Therefore, even without any industrial production of heat, an urban area tends to be warmer than the countryside that surrounds it.The burning of fuel, such as by cars, is not the only source of this increased heat. Two other factors contribute to the higher overall temperature in cities. The first is the heat capacity of the materials that constitute the city, which is typically dominated by concrete and asphalt. During the day, heat from the Sun can be conducted into these materials and stored—to be released at night. But in the countryside materials have a significantly lower heat capacity because a vegetative blanket prevents heat from easily flowing into and out of the ground. The second factor is that radiant heat coming into the city from the Sun is trapped in two ways: (1) by a continuing series of reflection among the numerous verticalimportant source of heat.B.Construction materials in the city are not asgood at keeping buildings warm as they are in the countryside.C.In the countryside the solar heat that flowsinto the ground flows out again quickly. D.Countryside vegetation prevents heat frombeing trapped in the ground.6. How is paragraph 3 organized?A.It describes two factors that contribute to theincreased heat of cities and then provides two causes for the second factor.B.It describes two causes discovered in anearly analysis of the increased heat of cities.C.It describes two factors that contribute to theincreased heat of cities and two other factors that work against it.D.It describes two well-established causes ofthe increased heat of cities and other two whose roles are less well understood.7.The word “configuration” in the passage is closest in meaning toA.locationB.historyC.temperatureD.shape8. According to paragraph 4, what can explain the substantial differences in temperature between one area and other within a well-developed heat island?A.The overall size of the heat island thatincludes the two reasonsB.The intensify of the heat island that includesthe two areasC.Differences between the two areas in thegeneral level of activity, including traffic D.Differences between the two areas in theinsulation materials used in construction9. Paragraph 4 supports the idea that a city’s heat-island intensity would increase ifA.the city went into an economic decline and surfaces that buildings present and (2) by the dust dome, the cloudlike layer of polluted air that most cities produce. Shortwave radiation from the Sun passes through the pollution dome more easily than outgoing longwave radiation does; the latter is absorbed by the gaseous pollutants of the dome and reradiated back to the urban surface.Cities, then, are warmer than the surrounding rural areas, and together they produce a phenomenon known as the urban heat island. Heat islands develop best under particular conditions associated with light winds, but they can form almost any time. The precise configuration of a heat island depends on several factors. For example, the wind can make a heat island stretch in the direction it blows. When a heat island is well developed, variations can be extreme; in winter, busy streets in cities can be 1.7℃warmer than the side streets. Areas near traffic lights can be similarly warmer than the areas between them because of the effect of cars standing in traffic instead of moving. The maximum differences in temperature between neighboring urban and rural environments is called the heat-island intensity for that region. In general, the larger the city, the greater its heat-island intensity. The actual level of intensity depends on such factors as the physical layout, population density, andlost populationB.the city’s economy shifted from hea vyindustry to health care and educationC.there was an upward trend in the average ageof the city’s residentsD.repair work on the streets slowed trafficthroughout the city10. According to paragraph 5, surfaces in the city are generally drier than surfaces in the countryside between periods of rainfall becauseA.in the city gentle rain is much more commonthan heavy rainB.high temperatures in the city speed up theprocess of evaporationC.in the city there are longer periods of dryweather between episodes of rainD.rainwater in the city cannot soak into mostsurfaces and quickly runs off11. The word “modified” in the passage is closest in meaning toA.changedB.blockedC.increasedD.weakened12. According to paragraph 5, which of the following isa factor responsible for the greater air turbulence in urban environments?A.The high speed of the winds travelling abovecitiesB.The greater rainfall totals recorded in citiesC.Attempts to reduce urban air pollutionD.The effects of tall buildings on airflow13. Look at the four squares [■] that indicate where the following sentence could be added to the passage.Another possibility is for the heat island to be stretched along the course of major rivers, since large waterways typically have a warming effect on the air directly above them.Where would the sentence best fit? productive activities of a metropolis.The surface-atmosphere relationships inside metropolitan areas produce a number of climatic peculiarities. For one thing, the presence or absence of moisture is affected by the special qualities of the urban surface. With much of the built-up landscape impenetrable by water, even gentle rain runs off almost immediately from rooftops, streets, and parking lots. Thus, city surfaces, as well as the air above them, tend to be drier between episodes of rain; with little water available for the cooling process of evaporation, relative humidities are usually lower. Wind movements are also modified in cities because buildings increase the friction on air flowing around them. This friction tends to slow the speed of winds, making them far less efficient at dispersing pollutants. On the other hand, air turbulence increases because of the effect of skyscrapers on airflow. Rainfall is also increased in cities. The cause appears to be in part greater turbulence in the urban atmosphere as hot air rises from the built-up surface.14. Cities create climatic conditions of their own through their physical structure and urban activities. Answer ChoicesA.The amount of heat produced in a city will bereduced when cities use the heat from cars to warm homes.B.The built-up landscape of the city readilybecomes a heat island, with greater waterrunoff and special climatic conditions such as low relative humidity and increased air turbulence.C.The materials from which cities are built andthe effects of pollution domes help make urban areas warmer than rural areas.D.Cities tend to be warmer than theirsurrounding areas, in part because they produce heat by burning fuel for heating, powering vehicles, and industrial production.E.In most cities, the heating that results fromsolar radiation is intensified by carbon dioxide, a gas that is present at very high concentrations in cities’ atmospheres.F.During periods without rainfall, the air incities heats up and causes winds to slow down, with the result that pollutants are not dispersed. Cities, then, are warmer than the surrounding rural areas, and together they produce a phenomenon known as the urban heat island. Heat islands develop best under particular conditions associated with light winds, but they can form almost any time. ■The precise configuration of a heat island depends on several factors. ■For example, the wind can make a heat island stretch in the direction it blows. ■When a heat island is well developed, variations can be extreme; in winter, busy streets in cities can be 1.7℃warmer than the side streets. ■Areas near traffic lights can be similarly warmer than the areas between them because of the effect of cars standing in traffic instead of moving.

By indicating that production was in line with market demands the author means that Dutch farmers were able toA.exceed other European countries inagricultural productionB.produce crops mat were similar tothose popular in other EuropeancountriesC.supply sufficient quantities of theagricultural products that the Dutchpopulation wanted to buyD.satisfy the demand for high qualityagricultural products from the Balticregion2. Which is 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.Buying imported grain led to the Dutchdemanding that other foodstuffs andconsumer goods be imported.B.Because the Dutch were able to importinexpensive grain, they had moneyavailable to create a demand for otherfood products and consumer goods. C.Keeping the price of grain low was aprimary goal of the Dutch at a timewhen they could not produce enoughgrain to provide for all their needs. D.The demand for other foodstuffs andconsumer goods forced the Dutch toimport grain and other products at atime when maintaining low prices wasespecially important.3. The phrase “Apart from” in the passage is closest in meaning toA.BesidesB.DespiteC.As a result ofD.Instead ofSeventeenth-Century DutchAgriculture Agriculture and fishing formed the primary sector of the economy in the Netherlands in the seventeenth century. Dutch agriculture was modernized and commercialized new crops and agricultural techniques raised levels of production so that they were in line with market demands, and cheap grain was imported annually from the Baltic region in large quantities. According to estimates, about 120,000 tons of imported grain fed about 600,000 people: that is about a third of the Dutch population. Importing the grain, which would have been expensive and time consuming for the Dutch to have produced themselves, kept the price of grain low and thus stimulated individual demand for other foodstuffs and consumer goods.（亚麻，茜草，油菜和烟草，啤酒花，芜菁）Apart from this, being able to give up labor-intensive grain production freed both the land and the workforce for more productive agricultural divisions. The peasants specialized in livestock husbandry and dairy farming as well as in cultivating4. According to paragraph 2, the increases demands on Dutch agriculture made by urban consumers had which of the following results?m A.Seasonal shortages of the productsconsumers most wantedB.Increased production of high-qualitygrain productsC.Raised prices charged by peasants tourban consumersD.Different ways of caring fordairy-producing animals5. The word “consumption” in the passage is closest in meaning toA.saleB.storageC.exportationD.utilization6. According to paragraph 3, the modernization of agriculture in the Netherlands was evident in all of the following ways EXCEPT:A.The production of fruits and vegetablesbecame a commercial venture.B.The wealthy stopped growing fruitsand vegetables in their gardens andgrew flowers instead.C.Horticultural produce was transportedto city markets by water.D.Many more people were able to affordto eat fresh fruits and vegetables.7. Select the TWO answer choices that, according to paragraph 4, indicate two methods people used to increase the productivity of their land. To receive credit you must select TWO answersA.They planted different crops indifferent sections of the farm eachyear.B.They used improved irrigationmethods to increase the yield of crops.C.They increased the use of fertilizers tosupply more nutrients to plants. industrial crops and fodder crops: flax, madder, and rape were grown, as were tobacco, hops, and turnips. These products were bought mostly by urban businesses. There was also a demand among urban consumers for dairy products such as butter and cheese, which, in the sixteenth century, had become more expensive than grain. The high prices encouraged the peasants to improve their animal husbandry techniques; for example, they began feeding their animals indoors in order to raise the milk yield of their cows.In addition to dairy farming and cultivating industrial crops, a third sector of the Dutch economy reflected the way in which agriculture was being modernized-horticulture. In the sixteenth century, fruit and vegetables were to be found only in gardens belonging to wealthy people. This changed in the early part of the seventeenth century when horticulture became accepted as an agricultural sector. Whole villages began to cultivate fruit and vegetables. The produce was then transported by water to markets in the cities, where the consumption of fruit and vegetables was no longer restricted to the wealthy.As the demand for agricultural produce from both consumers and industry increased, agricultural land became more valuable and people tried to work the available land more intensively and to reclaim more land from wetlands and lakes. In order to increase production on existing land, the peasants made more use of crop rotation and, in particular, began to apply animal waste to the soil regularly, rather than leaving the fertilization process up to the grazing livestock. For the first time industrial waste, such as ash from theD.They used new horticultural practicesto produce different varieties of plantsin the same section of the farm.8. The word “they” in the passage refers toA.merchantsB.hectaresC.windmillsD.drainage pumps9. According to paragraph 5, which of the following was an important reason why land-reclamation projects in the first half of the seventeenth century proceeded rapidly?A.Windmills became powerful enough torun drainage pumps efficiently.B.Merchants invested large amounts ofmoney in reclamation.C.High interest rates discouraged peoplefrom buying land already available. D.Reclaimed land was much moresuitable for agriculture than theexisting land.10. The word “legendary” in the passage is closest in meaning toA.continuousB.well documentedC.famousD.expensive11. The word “astonishing” in the passage is closest in meaning toA.incredibleB.unfortunateC.predictedD.evident12. Which of the following best describes the organization of the passage?A. A presentation of a theory and theevidence in favor of itB. A general statement followed by soap-boilers, was collected in the cities and sold in the country as artificial fertilizer. The increased yield and price of land justified reclaiming and draining even more land.The Dutch battle against the sea is legendary. Noorderkwartier in Holland, with its numerous lakes and stretches of water, was particularly suitable for land reclamation and one of the biggest projects undertaken there was the draining of the Beemster lake which began in 1608. The richest merchants in Amsterdam contributed money to reclaim a good 7,100 hectares of land. Forty-three windmills powered the drainage pumps so that they were able to lease the reclamation to farmers as early as 1612, with the investors receiving annual leasing payments at an interest rate of 17 percent. Land reclamation continued, and between 1590 and 1665, almost 100,000 hectares were reclaimed from the wetland areas of Holland, Zeeland, and Friesland. However, land reclamation decreased significantly after the middle of the seventeenth century because the price of agricultural products began to fall, making land reclamation far less profitable in the second part of the century.Dutch agriculture was finally affected by the general agricultural crisis in Europe during the last two decades of the seventeenth century. However, what is astonishing about this is not that Dutch agriculture was affected by critical phenomena such as a decrease in sales and production, but the fact that the crisis appeared only relatively late in Dutch agriculture. In Europe as a whole, the exceptional reduction in the population and the related fall in demand for grain sinceexamples and relevant detailsC. A analysis of a problem and its solutionD.

B.The richest people grew enough fruitsand vegetables to supply the entirecountry with fresh produce.C.An agricultural crisis that began inEurope did not affect Dutchland-reclamation projects.D.Specialization in dairy farming,industrial crops, and horticultureallowed the Dutch to be moreproductive than some other regions inEurope.nd reclamation and improvementallowed the Dutch to meet demands fortheir agricultural products.F.Because the Dutch had specialized the beginning of the seventeenth century had caused the price of agricultural products to fall. Dutch peasants were able to remain unaffected by this crisis for a long time because they had specialized in dairy farming industrial crops, and horticulture. However, toward the end of the seventeenth century, they too were overtaken by the general agricultural crisis.In addition to dairy farming and cultivating industrial crops, a third sector of the Dutch economy reflected the way in which agriculture was being modernized-horticulture. ■In the sixteenth century, fruit and vegetables were to be found only in gardens belonging to wealthy people. ■This changed in the early part of the seventeenth century when horticulture became accepted as an agricultural sector. ■Whole villages began to cultivate fruit and vegetables. ■The produce was then transported by water to markets in the cities, where the consumption of fruit and vegetables was no longer restricted to the wealthy.their agricultural output they were less susceptible to the crisis that Europe experienced from the beginning of the century.1.

The word “revised” in the passage is closest inRock Art of the AustraliaAboriginesEver since European first explored Australia, people have been trying to understand the ancient rock drawings and cavings created by the Aborigines, the original inhabitants of the continent. Early in the nineteenth century, encounters with Aboriginal rock art tended to be infrequent and open to speculative interpretation, but since the late nineteenth century, awareness of the extent and variety of Australian rock art has been growing. In the latter decades of the twentieth century there were intensified efforts to understand and record the abundance of Australian rock art.The systematic study of this art is a relatively new discipline in Australia. Over the past four decades new discoveries have steadily added to the body of knowledge. The most significant data have come from a concentration on three major questions. First, what is the age of Australian rock art? Second, what is its stylistic organization and is it possible to discern a sequence or a pattern of development between styles? Third, is it possible to interpret accurately the subject matter of ancient rock art, bring to bear all available archaeological techniques and the knowledge of present-day Aboriginal informants?The age of Australia’s rock art is constantly being revised, and earliermeaning toA.discussedB.raisedC.challengedD.changed6. 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 ways or leave out essential informationA.The oldest rock art sites have simplermotifs than the best known sites of Panaramitee North.B.Because motifs primarily associatedwith the Panaramitee region are common in the oldest sites the term Panaramitee style has become the general term for rock art of this type.C.Because the Panaramitee style is socommon in the older sites, researchers have described it most extensively. D.The motifs carved in the rocky surfaceof the Panaramitee region make up the oldest form of rock art discovered in Australia.7. According to paragraph 4, researchers have organized and structured Australian rock art by distinguishing between which of the following?A.Images found at Panaramitee North andimages found in other parts of Australia B.Images found in a particular type ofrock layer and images found in other types of rock layersC.Images that have geometric elementsand images that have figurative elementsD.Images that are typically found and datings have been proposed as the result of new discoveries. Currently, reliable scientific evidence dates the earliest creation of art on rock surfaces in Australia to somewhere between 30,000 and 50,000 years ago. This in itself is an almost incomprehensible span of generations, and one that makes Australia’s rock art the oldest continuous art tradition in the world.Although the remarkable antiquity of Australia’s rock art is now established, the sequences and meanings of its images have been widely debated. Since the mid-1970s, a reasonably stable picture has formed of the organization of Australian rock art. In order to create a sense of structure to this picture, researchers have relied on a distinction that still underlies the forms of much indigenous visual culture—a distinction between geometric and figurative elements. Simple geometric repeated patterns—circles, concentric circles, and lines—constitute the iconography (characteristic images) of the earliest rock-art sites found across Australia. The frequency with which certain simple motifs appear in these oldest sites has led rock-art researchers to adopt a descriptive term—the Panaramitee style—a label which takes its name from the extensive rock pavements at Panaramitee North in desert South Australia, which are covered with motifs pecked into the surface. Certain features of these engravings lead to the conclusion that they are of great age—geological changes had clearly happened after the designs had been made and local Aboriginal informants, when first questioned about them, seemed to know nothing of their origins. Furthermore, the designs were covered with “desertimage that are rarely found8. According to paragraph 4, all of the following are signs of the great age of the Panaramitee engravings EXCEPT:A.The engravings consisted of simpleanimal drawings.B.The engravings were covered with alayer of a substance known as “desert varnish”.C.Local Aborigines who were askedknew nothing about the origin of the engravings.D.Geologic changes had occurred afterthe engravings were made.9. Why does the author include information about Tasmania in paragraph 4?A.To provide evidence that thePanaramitee style is widespread and of great ageB.To prove that Aboriginal Australianscould not have made the carvings in TasmaniaC.To indicate how researchers havedetermined how long ago Tasmania separated from the mainlandD.To illustrate the importance ofgeometric rock art to tourism in Tasmania10. According to paragraph 5, the complex figurative style differs from the geometric style in that the complex figurative styleA.varies significantly from region toregionB.is more meaningfulC.appears on only a few types of rocksD.has changed little overtime11. According to paragraph 5, Lesley Maynard made which of the following suggestions about Australian rock art?A.There were a pattern of human figures varnish,” a glaze that d evelops on rock surfaces over thousands of years of exposure to the elements. The simple motifs found at Panaramitee are common to many rock-art sites across Australia. Indeed, sites with engravings of geometric shapes are also to be found on the island of Tasmania, which was separated from the mainland of the continent some 10,000 years ago.In the 1970s when the study of Australian archaeology was in an exciting phase of development, with the great antiquity of rock art becoming clear. Lesley Maynard, the archaeologist who coined the phrase “Panaramitee style,” suggested that a sequence could be determined for Australian rock art, in which a geometric style gave way to a simple figurative style (outlines of figures and animals), followed by a range of complex figurative styles that, unlike the pan-Australian geometric tradition tended to much greater regional。

听力原文 :Listen to part of a lecture in a biology class.(female professorNow, plants, like animals, and like us for that matter, need nutrients, substances that provide nourishments, to survive, thrive and grow. We get our nutrients from the food we eat. Plants, though, most plants anyway, absorb their nutrients from the soil, right, through their root systems? OK, but there are plants that don’t get their nutrients from the soil. The places they grow the soil is bad. So they get their nutrients from insects instead, from trapping and digesting insects. They are called carnivorous plants.Carnivorous plants capture insects in different ways. They have different trapping mechanisms: active traps and passive traps. A plant with an active trap, a good example is the Venus flytrap. The Venus flytrap actually moves to capture its prey or parts of it anyway. Its leaves, it has special leaves that are hinged in the middle the two halves of the leaves open and close sort of like a mouth to catch insects. And on these leaves is a sweet nectar that attracts insects. Insects like the sweet stuff. And when they get lured in and land on the leaf, wham! The leaf springs shut. It’s an active trap. And the insectsprings it so to speak. The leaf quickly closes to form a little cage, trapping the insect between the leaves. The Venus flytrap is then able to digest the insect and get its nutrients.But other carnivorous plants, their methods are passive. They don’t have any moving parts to trap things. They have passive traps, like the sundew plant. The sundew plant also produces a sweet nectar that attracts insects. Its leaves are full of little hairs that secrete sweet substance. But what happens when insects land on sundew’s leaves to get the sweet nectar? Well, unfortunately for the in sects, the hairs on the leaves also produce a super sticky glue-like substance. So an insect get stuck and can’t fly away. It basically get glued there allowing the sundew to digest it and absorb nutrients.Question:Using the example of the Venus fly trap and the sundew, describe two ways that carnivorous plants get theirnutrients.范文一:In the lecture, the professor talks about two ways carnivorous plants capture insects. The first way is active trap. For example, Venus fly trap has some parts that can move to catch the prey its leaves are hinged in the middle and the two parts of the leaves look like a mouth. Also its leaves have sweat nectar on them to attract the insects. When insects areattracted by the nectar and land on the leaves, the leaves spring shut and form little cages. Then Venus fly trap can digest the insects and get nutrients. The second way is passive trap. For example, the Sundew plant has no moving parts. It also has sweet nectar on its leaves. But its leaves are full of little hairs. When insects land on the leaves, hairs can produce super sticky glue substance. So the insects get stuck on the leaves and then Sundew plant can digest the insects and absorb nutrients.范文二:The lecture introduces two ways that carnivorous plants get their nutrients. The first way is act ive traps, the plant’s body or part of its body moves to catch preys. Such as Venus flytrap, they have sweet nectar to lure insects and have leaves that can close like a mouth. When insects land on its leaves, the leaves close to form a cage and shut the insects inside. Then they will be able to digest the insects and get the nutrients. The second way is passive traps, such assundew plant. The sundew plant has sweet substance and sticky stuff on its leaves; insects that were attracted by the scent will get stuck on its leaves. In this way, they catch the insects to get the nutrients they need.以上就是小编为大家准备的新托福 tpo23听力解释的部分内容,考生们可以根据自己备考的情况进行索取哦, 更多的 TPO 解释还在等着你哦。
