Firstly, I learned how to be sociable from friends. When I first entered a company, I was a loner. I didn’t understand the basic social rules. One of my friends, Lillian, gave me a lot of advice about how to behave in front of the boss and what to say in front of colleagues. Secondly, friends are my good-listeners. Many times I felt helpless and painful because of some frustrations, I went to my friends. They would sit in front of me, listening to my complaints or swear words and then comforted me. These are the things that neither my parents or other relatives can give me. 以上是给大家整理的托福TPO21口语Task2题目+满分范文，希望对你有所帮助!。

听力材料就个观点进行了逐一反驳。

下面是店铺整理的托福TPO21综合写作范文和听力原文，欢迎阅读!托福TPO21综合写作范文：The reading and listening materials have a conflict of opinions about genetic modification. The writer believes that it is beneficial to the society， which is contradicted by the following lecture.Firstly， the writer claims that genetically modified trees are more likely to survive since it is hardier than unmodified ones. However， the speaker casts doubt on this opinion by saying that natural trees tend to be genetically diverse， so there will always be some resistant kinds that get to survive when exposed to an environmental challenge. Genetically modified trees，on the other hand， are uniform in genes， which means they would all die if faced with a challenge that they are not designed for.Secondly， the author argues that genetically modified trees are more profitable to farmers， while the lecture views this issue from an opposite angle. According to her， the seeds of modified trees cost a lot and by law， farmers have to pay the company every time they plant.Thirdly， the passage states that genetically modified trees make it no longer necessary to overexploit wild trees. By contrast，in accordance with the professor， this claim does not hold water. It is because modified trees tend to grow more aggressively and would outcompete native trees for natural resources like sunlight，water and soil nutrition. As a result，modified trees wouldactually wipe out the native trees planted around them.托福TPO21综合写作阅读材料：Genetic modification, a process used to change an organism’s genes and hence its characteristics, is not being used to improve trees. Through genetic modification, it is possible to create trees that produce more fruit, grow faster, or withstand adverse conditions. Planting genetically modified trees on a large scale promises to bring a number of benefits.基因改良是通过改变有机体的基因，进而改变其性状的过程。

TPO21-1-1 原文：Geothermal EnergyEarth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes. It can also be harnessed to drive electric generators and heat homes. Geothermal energy becomes available in a practical form when underground heat is transferred by water that is heated as it passes through a subsurface region of hot rocks (a heat reservoir) that may be hundreds or thousands of feet deep. The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.By far the most abundant form of geothermal energy occurs at the relatively low temperatures of 80°to 180°centigrade. Water circulated through heat reservoirs in this temperature range is able to extract enough heat to warm residential, commercial, and industrial spaces. More than 20,000 apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin. Iceland sits on a volcanic structure known as the Mid-Atlantic Ridge. Reykjavik, the capital of Iceland, is entirely heated by geothermal energy derived from volcanic heat.Geothermal reservoirs with temperatures above 180°centigrade are useful for generating electricity. They occur primarily in regions of recent volcanic activity as hot, dry rock; natural hot water; or natural steam. The latter two sources are limited to those few areas where surface water seeps down through underground faults or fractures to reach deep rocks heated by the recent activity of molten rock material. The world's largest supply of natural steam occurs at The Geysers, 120 kilometers north of San Francisco, California. In the 1990s enough electricity to meet about half the needs of San Francisco was being generated there. This facility was then in its third decade of production and was beginning to show signs of decline, perhaps because of over development. By the late 1990s some 70 geothermal electric-generating plants were in operation in California, Utah, Nevada, and Hawaii, generating enough power to supply about a million people. Eighteen countries now generate electricity using geothermal heat.Extracting heat from very hot, dry rocks presents a more difficult problem: the rocks must be fractured to permit the circulation of water, and the water must be provided artificially. The rocks are fractured by water pumped down at very high pressures. Experiments are under way to develop technologies for exploiting this resource.Like most other energy sources, geothermal energy presents some environmental problems. The surface of the ground can sink if hot groundwater is withdrawn without being replaced. In addition, water heated geothermally can contain salts and toxic materials dissolved from the hot rock. These waters present a disposal problem if they are not returned to the ground from which they were removed.The contribution of geothermal energy to the world's energy future is difficult to estimate. Geothermal energy is in a sense not renewable, because in most cases the heat would be drawn out of a reservoir much more rapidly than it would be replaced by the very slow geological processes by which heat flows through solid rock into a heat reservoir. However, in many places (for example, California, Hawaii, the Philippines, Japan, Mexico, the rift valleys of Africa)the resource is potentially so large that its future will depend on the economics of production. At present, we can make efficient use of only naturally occurring hot water or steam deposits. Although the potential is enormous, it is likely that in the near future geothermal energy can make important local contributions only where the resource is close to the user and the economics are favorable, as they are in California, New Zealand, and Iceland. Geothermal energy probably will not make large-scale contributions to the world energy budget until well into the twenty-first century, if ever.----------------------------------------------------------------------------------------------------------------Paragraph 1: Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes. It can also be harnessed to drive electric generators and heat homes. Geothermal energy becomes available in a practical form when underground heat is transferred by water that is heated as it passes through a subsurface region of hot rocks (a heat reservoir) that may be hundreds or thousands of feet deep. The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.1.According to the processes described in paragraph 1, what is the relationship between radioactivity and the steam produced by geothermal heat?Geothermally heated steam is produced when water is exposed to radioactivity deep underground.When water is introduced into holes drilled thousands of feet in the ground, it becomes radioactive and turns to steam.Radioactivity heats Earth's interior rock, which in turn can heat water to the point it becomes steam.When a reservoir of steam in subsurface rock is produced by radioactivity, it is said to be geothermally heated.2.The word "practical" in the passage is closest in meaning tousableplentifuleconomicalfamiliarParagraph 2: By far the most abundant form of geothermal energy occurs at the relatively low temperatures of 80°to 180°centigrade. Water circulated through heatreservoirs in this temperature range is able to extract enough heat to warm residential, commercial, and industrial spaces. More than 20,000 apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin. Iceland sits on a volcanic structure known as the Mid-Atlantic Ridge. Reykjavik, the capital of Iceland, is entirely heated by geothermal energy derived from volcanic heat.3.The word "abundant" in the passage is closest in meaning toeconomicalfamiliarplentifuluseful4.According to paragraph 2, which of the following is true about heat reservoirs with a temperature in the range of 80° to 180° centigrade?They are under international control.They are more common than reservoirs that have a higher temperature.Few of them produce enough heat to warm large industrial spaces.They are used to generate electricity.Paragraph 3: Geothermal reservoirs with temperatures above 180° centigrade are useful for generating electricity. They occur primarily in regions of recent volcanic activity as hot, dry rock; natural hot water; or natural steam. The latter two sources are limited to those few areas where surface water seeps down through underground faults or fractures to reach deep rocks heated by the recent activity of molten rock material. The world's largest supply of natural steam occurs at The Geysers, 120 kilometers north of San Francisco, California. In the 1990s enough electricity to meet about half the needs of San Francisco was being generated there. This facility was then in its third decade of production and was beginning to show signs of decline, perhaps because of over development. By the late 1990s some 70 geothermal electric-generating plants were in operation in California, Utah, Nevada, and Hawaii, generating enough power to supply about a million people. Eighteen countries now generate electricity using geothermal heat.5.According to paragraph 3, what is the connection between underground faults and naturally occurring steam?Underground faults enable the heat from molten-rock material to escape upward to regions where it can heat surface water enough to produce steam.Underground faults are created by steam that is produced in geothermal reservoirs deep inside Earth.Underground faults create spaces in which natural steam is sometimes trapped. Underground faults allow surface water to reach deep rocks that are hot enough to turn it into steam.6.In paragraph 3, why does the author mention that in the 1990s The Geysers was in its thirddecade of production?To provide the historical context of the geothermal production of electricity in the United StatesTo imply that The Geysers was the first geothermal site to be put into production in CaliforniaTo help explain the signs of decline shown by The GeysersTo explain why 70 new geothermal sites were put into electricity production in the late 1990s7.Which of the following can be inferred from paragraphs 2 and 3 about geothermal reservoirs?V olcanic heat is associated only with geothermal reservoirs that have a temperature over 180°centigrade.More countries produce power from geothermal reservoirs than use them for heating buildings.Most geothermal reservoirs are suitable for producing electricity.A higher geothermal reservoir temperature is needed to generate electricity than is needed to heat homes.Paragraph 4: Extracting heat from very hot, dry rocks presents a more difficult problem: the rocks must be fractured to permit the circulation of water, and the water must be provided artificially. The rocks are fractured by water pumped down at very high pressures. Experiments are under way to develop technologies for exploiting this resource.8.According to paragraph 4, extracting heat from very hot, dry rocks is difficult in part becausethe underground rock must be fractured before heat can be removed from itthe water above the rock is under very high pressurethe rock breaks apart when water is pumped into itthe water circulated through the rock must be much cooler than the rock itself9.The word "exploiting" in the passage is closest in meaning tolocatingincreasingmaking use ofestimating the size ofParagraph 5: Like most other energy sources, geothermal energy presents some environmental problems. The surface of the ground can sink if hot groundwater is withdrawn without being replaced. In addition, water heated geothermally can contain salts and toxic materials dissolved from the hot rock. These waters present a disposal problem if they are not returned to the ground from which they were removed.10.How is the problem that the surface may sink related to the problem that water heated geothermally may contain toxic materials?Both problems could be solved by returning groundwater that is removed from an underground heat reservoir back to the reservoir after heat is extracted from it.The problem of sinking is more difficult to solve than is the problem of toxic materials. Land at the surface sinks because the rock beneath the surface is weakened when salts and toxic materials are removed from it in the process of extracting geothermal energy.Both problems are caused by the fact that the hot groundwater in a heat reservoir dissolves the rock, which weakens the rock and makes the water toxic with salt.Paragraph 6: The contribution of geothermal energy to the world's energy future is difficult to estimate. Geothermal energy is in a sense not renewable, because in most cases the heat would be drawn out of a reservoir much more rapidly than it would be replaced by the very slow geological processes by which heat flows through solid rock into a heat reservoir. However, in many places (for example, California, Hawaii, the Philippines, Japan, Mexico, the rift valleys of Africa)the resource is potentially so large that its future will depend on the economics of production.

Geothermal energy probably will not make large-scale contributions to the world energy budget until well into the twenty-first century, if ever.11.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.Heat flows through solid rock very slowly, so it takes a very long time for geological processes to produce a reservoir of geothermal energy.Geothermal energy is not renewable because heat flows very slowly through solid rock into or out of a heat reservoir.The heat quickly removed from a heat reservoir is replaced so slowly by geological processes that geothermal energy is not practically speaking, renewable.In most cases, heat travels into a heat reservoir so slowfy that it is a much quicker process to remove the heat from a reservoir than to replace it.12.In paragraph 6, the author implies that in California, Hawaii, the Philippines, Japan, Mexico, and the rift valleys of Africa the potential size of the geothermal resource is so large thatit might be economically worth developing these sites even though geothermal energy is not renewablethese sites will be the first geothermal energy sites to be developed with new technology these sites are likely to make a large-scale contribution to the world energy budget in the twenty-first centuryit does not matter whether they have naturally occurring deposits of hot water or steamEarth's internal heat, fueled by radioactivity, provides the energy for plate tectonics andcontinental drift, mountain building, and earthquakes.

Through genetic modification, it is possible to create trees that produce more fruit, grow faster, or withstand adverse conditions. Planning genetically modified trees on a large scale promises to bring a number of benefits.First, genetically modified trees are designed to be hardier than natural trees; that is, they are more likely to survive than their unmodified counterparts. In Hawaii, for example, a new pest-resistant species of payapa tree has been developed in response to ringshot virus infections that have repeatedly damaged the native papaya-tree population. Planning the genetically modified papayas has largely put an end to the ringshot problem. Moreover, genetically modified trees promise to bring a number of economic benefits to those who grow then. Genetically modified trees tend to grow faster, give greater yields of food, fruit, or other products- and be hardier. This allows tree farmers to get faster and greater returns on their farming investment and save on pesticides as well. [hardy: resistant to cold, 耐寒]Finally, the use of genetically modified trees can prevent overexploitation of wild trees. Because of the growing demand for firewood or building timber, many forests around the world are being cut down faster than they can be replaced. Introducing genetically modified trees designed for fast growth and highyield in given geographic conditions would satisfy the demand for wood in many of those areas and save the endangered native trees, which often include unique or rare species.Lecture:Sure, there are some benefits of planting genetically modified trees, but are these trees really as great as they first sound? When you examine the subject closely, here are some serious problems and costs associated with using genetically modified trees.First, genetically modified trees may be resistant to one particular condition, but that does not necessarily ensure their survival. You see, a typical non-modified tree population is genetically diverse. That means that, for most threatening conditions, for climates, insects and other pests, whatever, there will be at least some individual trees or any given species of trees that are resisted. So even if most of one kind of tree are killed, those few resisted ones will survive and ensure the survival of that species of tree. But genetically modified trees are genetically much more uniformed, so if they are exposed to an environmental challenge they have not been designed for, they will all die. So if the climate changes or a new pest invades the area, the genetically modified trees will likely be completely wiped out.Now as the second point, there are hidden costs associated with growing genetically modified trees. You see, the companies that genetically modified the trees tend to charge farmers much more for each seed than unmodified tree seeds would cost. Also, as you've grown the tree, you cannot collect the seeds and plant a new tree for free. By law, you have to pay the company every time you plant.And finally, genetically modified trees might actually cause even more damage to the local wild trees. You see, genetically modified trees are often grown more aggressively than natural trees do. And genetically modified trees are typically planted among natural trees. As a result, the genetically modified trees out compete the native trees for resources: sunlight, soil, nutrients and water, eventually crowding out the natural trees.Integrated writing sample essay:The professor claims that there are serious problems and costs associated with planting genetically modified trees, challenging the view in the reading passage that planting genetically modified trees on a large scale promises to bring tremendous benefits.First, the passage says that genetic modification is a good way to protect the trees against harsh natural conditions or possible infections because they are designed to be hardier. However, the lecturer claims that genetic modification does not ensure their survival because these trees are genetically more unified. So, if their genes are not designed for a particular condition, such as climate change or invasion of new pests, they might be eradicated altogether.Second, the passage says that genetically modified trees tend to grow faster, give more fruits and therefore provide greater financial returns for the growers. However, the lecturer points out that this is not the whole picture, because the seeds of genetically modified trees are more costly and the law requires farmers to pay for the company for every genetically modified tree that is planted.Finally, the passage says that genetic modification is a good solution for the protection of wild trees from overexploitation.But the professor points out that these trees are genetically more aggressive and typically planted among the natural trees. They might out compete the natural trees for natural resources and eventually edge them out.独立写作：For future career success, is the ability to relate well to other people more important than studying hard at school?1P: 咩个人都渴望获得success，但成功需要付出extraordinary efforts，而且还需要an element of luck和一定的社会关系；因为这是一个强调团队合作和cooperation的时代。

托福TPO21独⽴写作题⽬原⽂：Do you agree or disagree with the following statement?For success in a future job, the ability to relate well to people is more important than studying hard in school.Use specific reasons and examples to support your answer.托福TPO21独⽴写作满分范⽂：Everyone in the society is seeking for success in career, but what is the key factor of becoming successful? There are two choices – good networking and hardworking. Although someone tend to choose the first aspect, I definitely agree that hardworking at school should be a key factor of success. Without hardworking at school, success in the future cannot be guaranteed.To gain success in our future career, we must have solid knowledge of the field we choose. Under this circumstance, doing hard at school is the best way to quip ourselves with background knowledge. Although sometimes we may find things we have studied at school sort of unpractical, it is basic to handle real problems at work. Take myself as an example; I am now a senior major in journalism. I studied how to interview, how to write summaries and journals and how to make comments on subjects at school. I worked very hard and in the third year, I got a chance to be anintern in China Economic Daily. During this time, I totally put my knowledge into use and handle the real journalism with only a few problems. If I did not study hard and had no knowledge of journalism, how could I handle this internship?Another thing we can get from our hard work is the way of solving problems. During the time we studied at school, methods of learning and solving problems are also of great importance. These methods can be put into use even when we graduate, since we all have o update our knowledge and solve problems when we are at work. Again take myself as an example, when I did my internship, I had to write down a lot of details of a certain event in just a few minutes. It was really difficult, but since I had found out a method of writing fast at school, I could put down things on paper really efficiently. This method provided a lot of help.While some one may claim that we cannot ignore the importance of networking since a good networking may offer you greater chances to gain success. Anyway, I admit that we cannot get rid of a good networking. However, if we are not studying hard and haveno abilities to do things well, how can people pay attention on us or even provide us good opportunities? Hardworking is basic.All in all, hardworking should be the key factor of becoming successful. It provides foundations of our success in the future.以上是给⼤家整理的托福TPO21独⽴写作题⽬⽂本+满分范⽂，希望对你有所帮助!。

21. Do you agree or disagree with the following statement? For success in a future job, the ability to relate well to people is more important than studying hard in school. Use specific reasons and examples to support your answer.As a student in a complex society, we should learn the necessary knowledge in the school as well as the capability to relate well with other people. It is too simplistic to say which is more important between social skills and learning ability. I agree with this statement with reserved for several reasons. However, in terms of job, I prefer the ability to relate well to people is more essential in the long run than studying hard.Admittedly, as a student in school, the primarily purpose is studying and acquire the basic knowledge. This is because this learning ability will lay a solid foundation for our future development even though we probably forget most of them. Otherwise, the social skills in the future job is like a building a skyscraper lack of cement and bricks. Take a business negotiation as an example. You can not achieve a great success only with your negotiation skills when you deal with others in the situation that you lack expertise knowledge about your product. Therefore, I regard studying in school as the foundation to your future success.Further, the meaning of the ability to relate well to people in the job is significantly outweigh the specific knowledge you acquired. Specifically, everyone is interrelated and interdependent with others and this relationship requires you should equip with sophisticated communicating skills and social skills if you want to be a remarkable person in your job. This could be best illustrated with my country's culture. There is an old saying in my country: drinking ability is more essential than price in a business deal. Therefore, with deep-rooted intertwine relationship among this society; you must have the ability to relate well with your partner or companion beside your basic knowledge.What is more, there are lots of tasks that could be accomplished by different kinds of specialist and proficient. Nevertheless, to be a success leader in job, you must have the ability to communicate and coordinate with your team members with your sophisticated skills. According to the survey, most technology company boss even do not know the basic computer knowledge but they can be the boss and made their company increasingly giant due to their ability to relate well to people. That is to say, studying hard in school could make you require expertise in one domain but you never could be a great leader if you lacking the ability of social skills.Having considered all the discussion above, both of these aspects are crucial to a person's success in the future job, but I suppose that the former capability could make you fulfill higher achievement.。

可是呢，范文里也提到了基因改造树木的不好之处。

这些改造后的树可能会对周围的环境造成不好的影响。

想象一下呀，有一片美丽的森林，里面住着好多小动物，像小兔子、小松鼠之类的。

如果突然种上很多基因改造的树，这些树可能会把周围的水啊、养分啊都抢走。

就像在学校里，如果有一个小朋友总是抢别人的文具，那别的小朋友就没有办法好好写字画画啦。

那些小动物可能就没有足够的食物和水，因为这些基因改造树太“霸道”啦。

而且呀，基因改造树木可能会让一些害虫变得更厉害。

就好比我们玩游戏的时候，本来有一个小怪兽，我们可以很轻松地打败它。

可是突然这个小怪兽吃了一种神奇的东西，变得超级强大，我们就很难打败它了。

基因改造树木可能会让害虫吃了它之后，也变得超级难对付。

这样的话，农民伯伯的庄稼就会受到影响，就像我们种的小花小草，如果有很多很厉害的虫子来吃，它们就长不好啦。

在范文里还提到了一个很重要的点，就是基因改造树木的成本问题。

种这些树要花好多钱呢。

这就像我们想要买一个超级大的玩具城堡，但是这个城堡太贵了，我们可能要存很久很久的零花钱才能买得起。

对于种树来说，如果成本太高，很多地方可能就不会选择种这种基因改造的树啦。

所以呀，从这个托福写作tpo21综合写作的范文里我们可以学到好多东西。

我们看到一个东西有好的一面，就像基因改造树木能快速长大提供木材。

但也有不好的一面，像影响环境、让害虫变强大、成本高。

21考研英语二大作文参考范文：The Impact of Social Media on Interpersonal Relationships。

In recent years, social media has become an integral part of our lives, affecting the way we communicate and interact with others. While social media has brought about many positive changes, it has also had a significant impact on interpersonal relationships.One of the most noticeable effects of social media on interpersonal relationships is the way we communicate with others. With the rise of social media platforms such as Facebook, Twitter, and Instagram, people have become more reliant on these platforms to communicate with each other. While this has made it easier to stay in touch with friends and family, it has also led to a decline in face-to-face communication. Many people now prefer to communicatethrough text messages and social media posts rather than having a real conversation with someone. This has led to a decrease in the quality of our interactions with others, as we are no longer able to pick up on non-verbal cues and body language.Furthermore, social media has also had an impact on the way we form and maintain relationships. With the rise of online dating apps and social media platforms, people now have more opportunities to meet and connect with others. While this has made it easier to find potential partners,it has also led to a decline in the quality of our relationships. Many people now rely on social media to maintain their relationships, leading to a decrease in the amount of time they spend together in person. This has led to a decline in the quality of our relationships, as we are no longer able to build deep and meaningful connections with others.In addition, social media has also had an impact on the way we perceive ourselves and others. With the rise of social media influencers and celebrities, many people nowcompare themselves to others based on what they see on social media. This has led to an increase in feelings of inadequacy and low self-esteem, as people feel pressured to live up to the unrealistic standards set by social media. Furthermore, social media has also led to an increase in cyberbullying and online harassment, as people now have more opportunities to spread hate and negativity online.In conclusion, social media has had a significant impact on interpersonal relationships, affecting the way we communicate, form and maintain relationships, and perceive ourselves and others. While social media has brought about many positive changes, it has also led to a decline in the quality of our interactions with others. It is importantfor us to be mindful of the impact of social media on our interpersonal relationships and to make an effort to maintain meaningful connections with others in person. Only by doing so can we ensure that social media has a positive impact on our lives and relationships.。

TPO21The lecturer points out three different shortcomings of genetically modified trees. In the aspects of adaptation, economic lucrativeness, and environmental value, they never have overwhelming advantage over natural trees. That means the points made in the reading are partial and biased.First, genetic modification doesn’t necessarily make a natural tree more resistant to environmental adversities. Although genetic reconstructing may make a species stronger in a specific condition as the reading indicates, the new strain lakes the genetic diversity of a natural species. Thanks to the marginal differences between individuals, there can always be some survivors among natural species following a large interruption like climate change or pest invasion. But similar changes may cause the distinction of a genetically modified species for their unification in characteristics.Second, tree farmers don’t get guaranteed economic benefits if they plant genetically new strains. Companies that develop the new plants always charge farmers higher prices for artificially improved seeds, and receive money from farmers each time they grow the same plant. Such company policies andlaw will deprive farmers of the gaining mentioned in the reading.Third, genetically modified t rees don’t promise to protect wild trees. Actually, since they can grow faster with fewer resources, they are more ecologically invasive. Normally they outcompete natural trees by grasping natural resources like sunshine, water and soil. It’s far from the idealistic situation described in the reading.TPO22The lecturer refutes all the seemingly existing shortages of ethanol listed in the reading and holds that ethanol is quite likely a good replacement of gasoline as the future fuel. First, the application of ethanol will not create as much heat as that of gasoline does. Although the burning of ethanol will also generate carbon dioxide, it will not add to the severity of global warming. Since the production of ethanol requires the planting of corns, whose growth in turn requires carbon dioxide as nutrition, the raised amount of the unwanted gas will be offset therewith. This is the situation the reading doesn’t account for.Second, the production of ethanol doesn’t surely reduce the food supply for farm animals. Because ethanol can be made out of any part of the plant whose cell walls contain cellulose, the cost of the pants’ useful parts can be avoided. This advantage renders the worry of the reading totally unnecessary. Finally, the price of ethanol will be largely reduced if the scale of manufacture increases. According to statistics, if the manufacture scale, following heavier demand of consumers, can be enlarged by three times, its cost will be reduced by forty percents. Under such circumstance, the government subsidies mentioned in the reading shall no longer be needed.TPO23The lecturer holds that the main reason causing the overall decline in yellow cedar population is not yet decided. The proposed reasons in the reading, though responsible for the poor health of some individual plants, may not account for the decline of the whole species throughout the North American Continent.First, healthy yellow cedar trees can secret a chemical that is poisonous to insects feeding on its barks. Hence, it isunlikely that the cedar bark beetle can ever attack a plant before it gets ill or dead. The reading thus finds a misleading causal relationship between the insect and the tree. Second, bears cannot be blamed for large-scaled dying of yellow cedars across North America, although they might be responsible for the accidental dying for some individual plants. Another condition that can set bears free from this accusation is that yellow cedars growing on bear-free islands are also dying in large numbers. Hereby the reading material fails to spot the primary reason again.Third, cold climate can neither be blamed for the general failure of cedar population. The proof can be found in the trees’ wider recession in areas of lower elevation, where it’s warmer than on higher elevations. Though cold weather may have made cedars more sensitive, it cannot be the primary killer as the reading indicates.TPO24The lecturer extends possible explanations besides the conclusions made on the newly discovered T. Rex fossil andsuggests that the existing evidences can lead to something other than remaining animal tissues as suggested in the reading.First, the branching channels in that leg bone can quite likely be the colonies of bacteria, since bacteria always take the hollows in a bone structure and develop themselves following the organic material. And the soft substance inside the channels can also be the residues of these bacteria colonies, rather than once blood vessels suggested by the reading material.Second, the reading assumes the reddish spheres found in the bone to be red blood cells, finding credence from their color and size. But fossils of primitive organisms in the same area also contain similar reddish spheres. With the knowledge that such primitive organisms could not yet have evolved red blood cells, there is a good reason to doubt that these spots are only reddish minerals instead of blood cells. The reading again makes an imprudent conclusion here.Third, not a single sample of collagen found to this date is older than ten thousand years in age. The collagen found in the passage, however, is located in a seventy million-year-olddinosaur fossil. Since this tissue can hardly sustain such a long history, its source may not be in that prehistory animal, but in the skin of researchers working on it. So the final conclusion of the reading should also be seen with doubt. TPO25The reading material claimed that the vessels involving a copper cylinder surrounding an iron rod was not likely used as electric batteries in ancient times. By contrast, the lecturer argued that the conclusion was not convincing at all.First of all, the absence of wires could blame on the excavators, those local people.Since they had no recognition of the importance of the other materials,thus ever exsited electricity conductors could have been regarded as uninteresting and thrown away.In addition, the similarity between the copper cyclinders inside the jars and those discovered in ruins of selucia was not the neccessary reason to defend that the former should hold scrolls as well. One explanation was that the function of copper cyclinders was gradully changed from original use of holding scrolls to generate electricity later.Plus, electricity batteries were also of use in ancient time. Ancient people could have done electricity to complete magic results and healing purpose.Actually, the lecturer stated that the tingling people felt when they touched the vessles could be thought as invisible power even magic power. On the other hand,modern results had shown that elctricity was able to sitmulate muscle activities and reduce pains.。
