Charles Darwin was a rigorous, meticulous scientist. He spent nearly 20 years honing his analysis and polishing his prose before publishing his groundbreaking work, On the Origin of Species, in November 1859.Darwin’s slim volume was what we would call a “game changer,” a revolutionary work that fundamentally altered the way human beings see themselves and the natural world. Today most of us are familiar with his theory of “natural selection”—the foundation of modem evolutionary biology. But 150 years ago, Darwin was sailing into choppy waters. The Church of England had set rigid boundaries, and his thesis was clearly a challenge to the orthodox view that humans were a separate, unique part of God’s creation and that all life was divinely created and unchan geable.The establishment of the time mocked him. There was intense public debate. But Darwin was unflinching. Today his core idea that all animals and plants evolve and adapt through natural selection is the bedrock of modern life sciences. He opened the door to a new world—a door which religious fundamentalists and “intelligent design” proponents are still trying to close.Darwin’s long battle has disturbing echoes today. We, too, are trapped in the same sort of false illusion that stymied critical thought before his radical breakthrough, except that the myth that envelops us is more dangerous and even more deeply rooted.Our great sustaining myth is economic growth: faith that the economy can grow forever, that there are no limits to the wealth we can create from Earth’s natural resources. Growth, measured by an increasing Gross Domestic Product (GDP), is what drives government policy worldwide.The equation has been drummed into us for so long that it’s received wisdom. Growth equals prosperity and job s. Growth equals progress.Yet this is a relatively recent turn of events. Using the GDP as a tool to measure growth has only been around since the late 1940s when the UN System of National Accounts was developed. For most of human history, economic growth was a mere blip. Only the last eight generations of humans have experienced consistent growth. As the father of green economics, Herman Daly, points out: “Historically, steady state is the normal condition; growth is an aberration.” By “steady state,” Daly means an economy with a constant population and “the lowest feasible flows of matter and energy from the first stage of production to the last stage of consumption.”The latest global economic slump underlines our reliance on growth. What happens when the economy stumbles? Financial markets crash, property values plummet, bankruptcies pile up, unemployment soars, and social pathologies multiply. Thus the resurgence of Keynesian economics. Prime the pump with billions in government funds. Pray that tax breaks and fiscal stimulus will boost investment, production, and jobs.Yet the world already produces far too much stuff, a lot of it unnecessary and much of it useless. We go on churning out mountains of consumer goods because it’s good for growth. As long as the economy keeps growing, things will be okay. Growth keeps people employed, investment profitable, and the endless cycle of production and consumption spinning. Increases in productivity and the restless search for profits drive the process.Endless accumulation and expansion is the core of capitalism.Consider this: the world economy grew more than seven-fold from 1950 to 2000. It’s projected to do the same again by 2050. At current rates of growth (before the recent global meltdown), the economy was doubling every 15 years, a breathtaking number when you consider that it took all of human history to reach the $6 trillion world economy of 1950. As the US writers Fred Magdoff and John Bellamy Foster note: “No-growth capitalism is an oxymoron: when growth ceases, the system is in a state of crisis.” The upshot is that the natural environment, on which human life and the human economy depend, is sidelined—“not as a place with inherent boundaries within which human beings must live together with Eart h’s other species, but as a realm to be exploited in a process of growing economic expansion.”The uncomfortable and inconvenient truth is that the physical resources of the biosphere are finite. We’re not approaching the ecological limits to growth; we’r e well past them. And in the process we are fouling the planet with our wastes and threatening the natural systems on which humanity and all other species depend.The hard statistics of ecological decline could fill a library. We’re chewing through massiv e quantities of both renewable and non-renewable resources at a breakneck speed.In 2005, the UN Millennium Ecosystem Assessment, a collaborative work of more than 10,000 scientists, found that 60% of “ecosystem services”—things like climate regulation, the water cycle, pollination, global fisheries, natural waste treatment—were being degraded or used unsustainably. “Human activity is putting such a heavy strain on Earth’s natural functions,” the report warned, “that the ability of the planet’s ecosystems to sustain human endeavor can nolonger be taken for granted.”The new familiar Ecological Footprint model supports this conclusion. It’s a way of asking how much we’re extracting from the planet to live the way we do. Conventional economics tends to see the environment as a subset of the economy. The footprint approach does the reverse, comparing humanity’s ecological impact—resources consumed and waste produced—with the amount of productive land and water available to supply key ecosystem services. It deals in averages so the rich/poor divide is blurred. But the message is clear. It takes about 1.8 hectares to sustain the average person on Earth. Those of us in the rich world are way above the average: Canadians each use about eight hectares, and Americans use 10, more than five times the average.In 1961, human beings used about half of Earth’s biocapacity; by 2006 we were using 44% more than is available. Mathis Wackemagel, one of the founders of the ecological footprint system, says we will need the equivalent of two Earths by the late 2030s to keep up with our demands. Ecologists call this phenomenon “overshoot.” It’s a temporary state that becomes increasingly untenable as stocks of resources are depleted.Wackernagel again says: “Since the 1980s, we’ve been drawing down the biosphere’s principal rather than living off its annual interest. To support our consumption, we have been liquidating resource stocks and allowing carbon dioxide to accumulate in the atmosphere.”Oil is the main culprit. The burning of fossil fuels, especially petroleum, powers the global economy. Oil is an extraordinary feat of concentrated energy: three large teaspoons of crude contain about the same amount of energy as eight hours of human manual labor. Geologist Colin J. Camp bell hit the nail on the head: “It’s as if each one of us had a team of slaves working for us for next to nothing.”Napoleon said that an army marches on its stomach; our modern globalized economy marches on oil. But it’s a Faustian bargain. The costs now exceed the benefits. Take the climate system, a key “natural service” threatened by human-made greenhouse gas emissions, mostly CO2, the main by-product from the combustion of fossil fuels. The more oil and coal we bum, the more CO2 is pumped into the atmosphere and the more we tip the balance.Leading climate scientists say a target of 350 parts per million (ppm) of CO2 might avoid dangerous climate change. We’re currently at 390 ppm and projected to hit 650 ppm by the end of this century. This translate s into an average increase in global temperature of about 4°C. If this projection plays out, we’re in big trouble. Large parts of Africa, China, India, and Latin America would become desert. Have you heard the term “environmental refugees”? Keep it in mind, because you’re going to be hearing it a lot more in the years ahead.Even on its own terms, growth isn’t working. We avoid talking about the skewed distribution of the planet’s wealth and income, dreaming instead that we can grow our way out of the prob lem. So the richest 20% of the world’s population consumes the lion’s share of resources, while the poorest 80% have to get by on the crumbs. And the ratios are getting worse. Growth is an excuse for continued inequality. But, more importantly, countless studies show that beyond a certain point higher levels of material consumption do not lead to increased well-being or happiness.Per capita GDP has tripled in the United States since 1950, but the percentage of people who say they are happy has declined since the 1970s. Richard Wilkinson and Kate Pickett, in their book The Spirit Level, note that poor nations with lower inequality have higher levels of well-being than richer but more unequal nations. We place growth above equality and pay a price in what’s called “the hidden injuries of class.” Shorter, unhealthier, and unhappier lives addicted to a mindless consumerism that is depleting the planet’s resources.Free market cheerleaders believe that technology and human ingenuity will solve the problem. The economy can be “de-coupled” from material inputs, they claim, and improved technology will allow us to produce more wealth with less energy, materials, and waste. This is whistling in the dark. Between 1970 and 2000, rich countries saw impressive gains in energy efficiency of up to 40%; but average improvements of 2% a year were eclipsed by growth rates of 3% or more. Increased technical efficiency is swamped by increased consumption.A recent report by the New Economics Foundation found that, to stabilize carbon emissions at 350 ppm by 2050, the carbon intensity of the global economy would need to fall by 95%. Ramping up GDP without improving technological efficiency leads to more environmental damage. Yet improving efficiency leads to more growth, which leads to the same result.We’ve been captured by a myth far more alluring than the one that Charles Darwin confronted 150 years ago: the dream of perpetual economic growth. In the North we have been living beyond our ecological means for decades, consuming too much and producing more waste than the environment can absorb, while inequality grows.The global population is expected to jump by 3 billion in the next 40 years—more than the entire population in 1950.Most of that increase will be in the South, where poverty is entrenched and living standards desperate. How will those next three billion live? Justice demands that we in the rich countries ratchet back our growth and clear some space for those who need it. The fate of planet Earth may depend on it.Are we up to it?The economy is a human construct. It’s not an act of God. We made it, we can change it.。

By the millions they come, the ambitious and the down-trodden of the world drawn by the strange magnetism of urban 46 . For centuries the progress of civilization has been 47 by the rigid growth of cities. Now the world is 48 to pass a milestone: more people will live in urban areas than in the countryside.Explosive population growth 49 a torrent of migration from the countryside are creating cities that dwarf the great capitals of the past. By the 50 of the century, there will be fifty-one “megacities” with populations of ten million or more. Of these, eighteen will be in 51 countries, including some of the poorest nations in the world. Mexico City already 52 twenty million people and Calcutta twelve million. According to the World Bank, 53 of Africa’s cities are growing by 10% a year, the swiftest 54of urbanization ever recorded.Is the trend good or bad? Can the cities cope? No one know 55 .

But the findings are controversial and have launched all kinds of crank notions about using music to make kids smarter. The hype, he warns, has gotten out of hand.But first, the essence: Is there something about the brain cells work to explain the effect? In 1978 the neuroscientist Ver non Mountcastle devised a model of the neural structure of the brain’s gray matter. Looking like a thick band of colorful bead work, it represents the firing patterns of groups of neurons. Building on Mountcastle, Shaw and his team constructed a model of t heir own. On a lark, Xiaodan Leng, who was Shaw’s colleague at the time, used a synthesizer to translate these patterns into music. What came out of the speakers wasn’t exactly toe-tapping, but it was music. Shaw and Leng inferred that music and brain-wave activity are built on the same sort of patterns.“Gordon is a contrarian in his thinking”, says his longtime friend, Nobel Prize-winning Stanford physicist Martin Perl. “That’s important. In new areas of science, such as brain research, nobody knows how to do it.”What do neuroscientists and psychologists think of Shaw’s findings? They haven’t condemned it, but neither have they confirmed it. Maybe you have to take them with a grain of salt, but the experiments by Shaw and his colleagues are intriguing. In March a team led by Shaw announced that young children who had listened to the Mozart sonata and studied the piano over a period of months improved their scores by 27% on a test of ratios and proportions. The control group against which they were measured received compatible enrichment courses-minus the music. The Mozart-trained kids are now doing math three grade levels ahead of their peers, Shaw claims.Proof of all this, of course, is necessarily elusive because it can be difficult to do a double-blind experiment of educational techniques. In a double-blind trial of an arthritis drug, neither the study subjects nor the experts evaluating them know which ones got the test treatment and which a dummy pill. How do you keep the participants from knowing it’s Mozart on the CD?61. In the first paragraph Gordon Shaw’s concern is shown overA.the open hostility by the media towards his findings.B.his strength to keep trying out the “Mozart effect”.C.a widespread misunderstanding of his findings.D.the sharp disagreement about his discovery.62. Shaw and Leng’s experiment on the model of their own seems to be based on the hypothesis thatA.listening to Mozart could change the brain’s hardware.B.brain-waves could be invariably translated into music.C.listening to music could stimulate brain development.D.Toe-tapping could be very close to something musical.63. The remarks made by Martin Perl in Paragraph 3 about Gordon Shaw could be taken asA.neuroscientists and psychologists.B. Shaw and his colleagues.C. Shaw and his colleagues.D. the experiments by Shaw and his teamE. Shaw’s findings.66. According to the author, proof of what Shaw claims is difficult becauseA.the control group will also enjoy the same kind of Mozart.B.some educational techniques need re-evaluation.C.the double-blind experiment is not reliable and thus rejected by Shaw.D.participants cannot be kept from knowing what is used in the test.Passage TwoSometimes opponents of capital punishment horrify with tales of lingering death on the gallows, of faulty electric chairs, or of agony in the gas chamber. Partly in response to such protests, several states such as North Carolina and Texas switched to execution by lethal injection. The condemned person is put to death painlessly, without ropes, voltage, bullets, or gas. Did this answer the objections of death penalty opponents? Of course not. On June 22, 1984, The New York Times published an editorial that sarcastically attacked the new “hygienic” method of death by injection, and stated that “execution can never be made humane through science”. So it's not the method that really troubles opponents. It’s the death itself they consider barbaric.Admittedly, capital punishment is not a pleasant topic. However, one does not have to like the death penalty in order to support it any more than one must like radical surgery, radiation, or chemotherapy in order to find necessary these attempts at curing cancer. Ultimately we may learn how to cure cancer with a simple pill. Unfortunately, that day has not yet arrived. Today we are faced with the choice of letting the cancer spread or trying to cure it with the methods available, method that one day will almost certainly and would certainly delay the discovery of an eventual cure. We may not like the death penalty, but it must be available to punish crimes of cold-blooded murder, cases in which any other form of punishment would be inadequate and, therefore, unjust. If we create a society in which injustice is not tolerated, incidents of murder-the most flagrant form of justice-will diminish.67.

What type of writing is mostly adopted in this passage?A.Narration.B.Classification.C.Exemplification.D.Persuasion.Passage ThreeShyness is a nearly universal human trait. Almost everyone has bouts of it, and half of those surveyed describe themselves as shy. Perhaps because it’s so widespread, and because it suggests vulnerability, shyness is often an endearing trait: Princess Dian a, for example, won millions of admirers with her “Shy Di” manner. The human species might not even exist if not for an instinctive wariness of other creatures. In fact, the ability to sense a threat and a desire to flee are lodged in the most primitive regions of the brain.But at some life juncture, roughly 1 out of every 8 people becomes so timid that encounters with others turn into a source of overwhelming dread. The heart races, palms sweat, mouth grows dry, words vanish, thoughts become cluttered, an d an urge to escape takes over. This is the face of social phobia (also known as “social anxiety disorder”), the third most common mental disorder in the United States, behind depression and alcoholism. Some social phobics can hardly utter a sentence without obsession over the impression they are making. Others refuse to use public restrooms or talk on the telephone. Sometimes they go mute in front of the boss or a member of the opposite sex. At the extreme, they built a hermitic life, avoiding contact with others.Though social anxiety’s symptoms have been noted since the time of Hippocrates, the disorder was a nameless affliction until the late 1960s and didn’t make it way into psychiatry manuals until 1980. As it became better known, patients previously thought to suffer panic disorder were recognized as being anxious only in social settings. A decade ago, 40 percent of people said they were shy, but in today’s “nation of strangers” – in which computers and ATMs make face-to-face relations less and less common – that often favored by those who fear human interaction, greases the slope from shyness to social anxiety. If people were slightly shy to begin with, they can now interact less and less, and that will make the shyness much worse.73. According to Paragraph One, shyness isA.against human nature.B. completely an endearing trait.C. so widespread that a problem may arise.D. essential to the survival of the human species.74. The author suggests that our ability to sense a threat and desire to fleeA.are connected with types of shyness.B.make us more timid and less successfulC.distinguish humans from other creatures.D.are the results of the influence of our environment.75. Which is NOT mentioned as a sign of social anxiety disorder?A.Speechl ess in front of one’s supervisor.B.Unwilling to go to the public toilets.C.Getting drunk in social settings.D.The heart pumping fast.76. The term “social anxiety disorder” was coinedA. at the time of ancient meditation.B. in the 1960s.C. in 1980.D. a decade ago.77. It is shown that the most common mental disorder in the U.S. isA. depression.B. alcoholism.C. social phobia.D. panic disorder.78. What is the cited attitude of some psychologists towards the Internet culture?A.It is the main cause of social phobia.B.It is destructive and thus should be kept away from the youth.C.It encourages peple who are rather inhibited to communicate more freely.D.It helps accelerate the degradation from shyness to social phobia.Passage FourBenjamin Day was only 22 years old when he developed the idea of a newspaper for the masses and launched his New York Sun in 1833, which would profoundly alter journalism by his new approach. Yet, several conditions had to exist before a mass press could come into existence. It was impossible to launch a mass-appeal newspaper without invention of a printing press able to produce extremely cheap newspaper affordable almost to everyone. The second element that led to the growth of the mass newspaper was the increased level of literacy in the population. The then increased emphasis on education led to a concurrent growth of literacy as many people in the middle and lower economic groups acquired reading skills. The trend toward “democratization” of business and politics fostered the creation of a mass audience responsive to a mass press.Having seen others fail in their attempts to market a mass-appeal newspaper, he forged ahead with his New York Sun, which would be a daily and sell for a penny, as compared to the other dailies that went for six cents a copy. Local happenings, sex, violence, features, and human-interest stories would constitute his content. Conspicuously absent were the dull political debates t hat still characterized many of the six-cent papers. Within six months the Sun achieved a circulation approximately 8,000 issues, far ahead of its nearest competitor. Day’s gamble had paid off, and the penny press was launched.James Gordon Bennett, perhaps the most significant and certainly the most colorful of the individuals imitating Day’s paper, launched his New York Herald in 1835, even more of a rapid success than the Sun. Part of Bennett’s success can be attributed to his skillful reporting of crime news, the institution of a financial page, sports reporting, and an aggressive editorial policy. He looked upon himself a reformer, and wrote in one of his editorials: “I go for a general reformation of morals. … I mean to begin a new movement in the progress of civilization.”Horace Greeley was another important pioneer of the era. He launched his New York Tribune in 1841 and would rank third behind the Sun and Herald in daily circulation, but his weekly edition was circulated nationally and proved to be a great success. Greeley’s Tribune was not as sensational as its competitors. He used his editorial page for crusades and causes. He opposed capital punishment, alcohol, gambling and tobacco. Greeley also favored women’s rights. Greeley never talked down to the mass audience and attracted his readers by appealing to their intellect more than to their emotions.The last of the major newspapers of the penny-press era began in 1851. The New York Times,edited by Henry Raymond, promised to be less sensational than the Sun or Herald and less impassioned than Greeley. The paper soon established a reputation for objective and reasoned journalism. Raymond stressed the gathering of foreign news and served as foreign correspondent himself in 1859. The Times circulation reached more than 40,000 before the Civil war.79. Which is NOT mentioned as the contributing element in the launch of the mass press?A.The upgraded educational level of the masses.B.The increased wealth of the population as a whole.C.The democratic background and drive of the general publicD.The lowered cost of newspaper production.80. The New York Sun rarely featuredA.business newsB.women’s pages.C.lengthy discussion about politics.D.local shipment information.81. Which of the following papers issued a nationally circulated edition?A. The New York Tribune.B.The New York Sun.C.The New York Herald.D.The New York Times.82. Which of the following papers is viewed as the most dispassionate one?A The New York Tribune.B. The New York Sun.C. The New York Herald.D. The New York Times.83. The penny-press approach was pioneered byA.Henry Raymond.B. James Gordon Bennett.C. Benjamin day.D. Joseph Pulitzer84. It can be inferred thatA.the New York Times had the largest daily circulation at that time.B.the papers before the penny-press era only appealed to a small circle of readers.C.the success of the four papers lies in their endeavor to improve peple’s literacy.D.the paper’s being sensational was not favored by a majority of American readers.85. The main purpose of the passage is toA.give a brief introduction to the growth of the mass newspaper.B.trace the cause of the failures of the six-cent papers.C.find out which was the most significant newspaper of that time.D.show how a mass-appeal newspaper made a great fortune.Passage FiveInstead of advancing the public discussion of biotechnology, David Shenk succeeds merely in displaying his general ignorance and unfounded fears in his recent article “Biocapitalism”. His claim that “no living creature has ever before been able to upgrade its own operating system” ignores transduction (the act or process of transferring genetic material or characteristics from one bacterial cell to another) and bacterial conjugation (the temporary union of two bacterial cells), which are ways organisms have “upgraded” their own genomes with novel DNA f or hundreds of millions of years. A first-year biology major could have told him that. For Shenk to suggest that his daughter may someday use a before-birth genetic test for “quick-wittedness” is extremely dull-witted, ignoring the complexity of polygenetic traits while embracing a shallow genetic determinism. Nurture-utterly absent from his discussion-really does matter.Finally, worrying about the effects on the gene pool of a “culture in which millions choose the same desirable genes” is worse than point less. The United Nations projects an approximate human population of eight billion by the year 2020. Even if Shenk’s worst fears are realized, and the wealthy parents of 100 million children can and do select for a polygenetic trait-say, blue eyes-this would represent only a modest shift in the gene pool of 1 in 80, or 1.25 percent, assuming that none of those children would otherwise have been born with blue eyes. But what truly matters for the gene pool in the 1,000-year-long run is the capacity of this trait to grant reproductive success in subsequent generations. Whatever advantage blue eyes currently grant in acquiring a mate presumably derives in part from the trait’s relative scarcity. Elementary economics shows that if you flood the market with an asset, you diminish the relative value of that asset: more blue eyes will make blue eyes less sexy. Is it really too much to expect familiarity with either biology or economics from an essay entitled “Biocapitalism”?86. The purpose of David Shenk’s writing is most probably toA.draw the public’s attention to “biocapitalism”.B.cover his general ignorance about “biocapitalism”.C.show his approval of the advancement in biotechnology.D.Report his success in biotechnological research.87. According to the author, Dav id Shenk’s claim about the upgrading of living creaturesA.is obviously a fault.B. is comprehensible to college students.C. is identical to his own argument.D. will be testified by his daughter.88. What does David Shenk worry about?A.The capacity of the gene pool.B.The nurture of subsequent generations.C.The dramatic increase of world population.D.The consequences of excessive genetic shifts.89. The author’s explanation of people’s preference to blue eyes is thatA.blue eyes are purely inherited.B.few people have blue eyes.C.blue eyes are less sexy.D.people with blue eyes are usually wealthy.90. The tone of this passage is mainlyA. humorous.B. matter-of-fact.C. bitter and ruthless.D. emotional.PAPER TWOPART V TRANSLATION (10 points, 25 minutes)Directions: Put the following passage into Chinese.

学习数学挫折经历英文作文Learning from Mathematical Setbacks: A Transformative JourneyMathematics, a subject often perceived as rigid and unforgiving, has been a constant companion in my academic journey. While the allure of its logical precision and intricate problem-solving has always captivated me, I have also faced my fair share of challenges and setbacks along the way. In this essay, I will share my personal experiences with the struggles and triumphs of learning mathematics, and how these experiences have shaped my growth and resilience.From a young age, I have always been drawn to the elegance and beauty of mathematical concepts. The ability to manipulate numbers and symbols to arrive at a precise solution was both fascinating and empowering. However, as I progressed through my educational journey, I encountered moments where the subject seemed to elude me, leaving me feeling frustrated and discouraged.One particular incident that stands out in my memory occurred during my sophomore year in high school. I was tackling a complex problem in my Calculus class, one that required a deep understanding of differentiation and integration. Despite my bestefforts, I found myself struggling to grasp the underlying principles and apply them effectively. As the class moved forward, I found myself falling further behind, unable to keep up with the pace and complexity of the material.The feeling of inadequacy was overwhelming. I had always prided myself on my academic abilities, and the thought of not being ableto master a subject as fundamental as mathematics was deeply unsettling. I found myself questioning my own capabilities and wondering if I had what it took to succeed in this field.It was at this pivotal moment that I realized the true value of perseverance and a growth mindset. Instead of giving up or accepting defeat, I decided to take a step back and re-evaluate my approach to learning mathematics. I recognized that the path to mastery was not a linear one, and that setbacks were an inevitable part of the learning process.With renewed determination, I began to seek out additional resources and support. I reached out to my teacher, who graciously provided me with personalized guidance and extra practice problems.I also immersed myself in online tutorials, study groups, and mathematical forums, where I could learn from the experiences of others who had overcome similar challenges.As I delved deeper into the subject, I began to appreciate the nuances and complexities of mathematics in a way I had never done before. What was once a source of frustration became a source of fascination and intellectual stimulation. I discovered that the process of problem-solving was not just about finding the right answer, but about developing a deeper understanding of the underlying principles and concepts.Through this journey, I also learned the importance of embracing failure as an opportunity for growth. Instead of viewing mistakes as a weakness, I learned to see them as valuable learning experiences. I would carefully analyze my thought processes, identify the gaps in my knowledge, and use that information to refine my approach and strengthen my skills.As I continued to persevere and push through the challenges, I began to see tangible progress in my understanding of mathematics. The once-daunting problems became more manageable, and I found myself able to tackle increasingly complex concepts with confidence and ease.This transformation was not just limited to my academic performance; it also had a profound impact on my personal development. The resilience and problem-solving skills I honed through my struggles with mathematics have become invaluableassets in other areas of my life. I have learned to approach challenges with a more open and adaptable mindset, and to view setbacks as opportunities for growth and learning.In conclusion, my journey with learning mathematics has been a transformative experience. While the initial setbacks and frustrations were daunting, they ultimately served as the catalyst for my personal and academic growth. By embracing a growth mindset, seeking out support, and persevering through the challenges, I have not only become a more proficient mathematician but also a more resilient and adaptable individual. This experience has taught me the invaluable lesson that true success is not about perfection, but about the willingness to learn, grow, and overcome obstacles along the way.。
长难句翻译100句(7)1. But it is a little upsetting to read in the explanatory notes that a certain line describes a fight between a Turkish and a Bulgarian officer on a bridge off which they both fall into the river--and then to find that the line consists of the noise of their falling and the weights of the officers, "Pluff! Pluff! A hundred and eighty-five kilograms."但是让人感到不快的是,我们从注释中得知某诗行讲述的是一个土耳其军官和一个保加利亚军官在桥上动手打架并双双掉进河里的事情,而后我们却发现该行诗中不过只充斥着"扑通,扑通,185公斤重"这类对他们落水时的动静以及对军官们体重的描写时。

打破固化思维作文英文回答:Breaking rigid thinking is essential for personalgrowth and development. When we are stuck in rigid thinking, we limit our potential and miss out on new opportunities.It's important to challenge our own beliefs and be open to new ideas and perspectives.One example of breaking rigid thinking is when I usedto believe that success only came from following atraditional career path. I thought that I had to go to college, get a stable job, and work my way up the corporate ladder. However, I realized that this belief was holding me back from pursuing my true passions. I broke free from this rigid thinking by exploring alternative career paths and eventually found success as a freelance writer. This experience taught me the importance of being open-mindedand flexible in my thinking.Another example is when I used to believe that failure was a sign of weakness. I was afraid to take risks and try new things because I thought that failure would reflect poorly on my abilities. However, I learned that failure is a natural part of the learning process and is actually an opportunity for growth. By breaking free from this rigid thinking, I was able to take more risks and ultimately achieve greater success in both my personal and professional life.中文回答:打破固化思维对于个人成长和发展至关重要。
大学改变生活英语作文College life is a significant phase in ones life that brings about numerous changes both in terms of personal growth and the way one perceives the world.

Four Laws of Ecology1 In broad outline,there are environmental cycles which govern the behavior of the three great global systems:the air,the water,and the soil.Within each of them live many thousands of different species of living things.Each species is suited to its particular environmental niche,and each,through its life processes,affects the physical and chemical properties of its immediate environment.1概括来讲,地球的三大系统—空气、水和土壤的行为由环境循环所决定。
每个系统中都生活着成千上万个不同物种的生物,每个物种都有与之相适宜的独特的环境生位,并且每一物种,在其整个生命历程中,都影响着它的周边环境的物理和化学特性。
2 Each living species is also linked to many others.These links are bewildering in their variety and marvelous in their intricate detail.An animal,such as a deer,may depend on plants for food;the plants depend on the action of soil bacteria for their nutrients;the bacteria in turn live on the organic wastes dropped by the animal on the soil.At the same time.the deer is food for the mountain lion. Insects may live on the juices of plants or gather pollen from their flowers.Other insects suck blood from animals.Bacteria may live on the internal tissues of animals and plants.Fungi degrade the bodies of dead plants and animals.All this,many times multiplied and organized species by species in intricate,precise relationships,makes up the vast network of life on the earth.2每个生物物种也与许多其他的物种相联系。

Rigid growth characteristic of demand for oil in China’sagro-productionLihong Wang and Zhihong TianCollege of Economics and Management,China Agricultural University,Beijing,People’s Republic of ChinaAbstractPurpose –The demand for oil in agricultural production increases continuously with the world oil price soaring,reflecting a rigid growth characteristic,but there are no clear reasons for this.The purpose of this paper is to assess the essential reasons of this issue in theoretical and empirical perspectives.Design/methodology/approach –The paper develops the model of derived demand for petroleum in agro-production;analyzes the effect on agricultural labor-machinery due to the changes in relative price of input factors;and reveals the reasons for the rigid growth of the demand for farm diesel;as well as estimates the substitution of agricultural machine for labor.Findings –The results indicate that the rigid growth characteristic of the demand for farm diesel is due to the adjustment of the product and factor markets;and the most important reason is the changes in structure of the agro-production inputs caused by the relative soaring price of agricultural labor-machinery.Practical implications –The government should attach importance to its impact on farmers and take effective measures to insure the stable development of agricultural production.Originality/value –This research investigates the main reasons for the rigid growth characteristic of demand for oil in China’s agro-production from a novelty perspective.The proposed conceptual model is unique,it analyzes the substitution of agricultural mechanical for labor from the perspective of changes in relative price,and selects the two level constant elasticity substitution production functions to estimate the substitution of agricultural machinery for labor.Keywords Economic growth,Petroleum,Oil industry,China Paper type Research paper1.IntroductionThe relationship between agricultural production and petroleum is very close.Oil agriculture changed the path of world agricultural development,and pushed the agricultural production to a new development stage,so that the crop production growth rate exceeded the population growth rate,which declared the Malthus prediction bankrupt.However,oil agriculture is a high-input and high-yield agricultural development pattern.Based on fossil energy sources,oil agriculture adopts agricultural machinery and agrochemicals massively.This development mode not only consumes a large amount of oil resources,but also causes serious environmental pollution.It draws both consumers and researchers’attention.There has been a considerable amount ofThe current issue and full text archive of this journal is available at /1756-137X.htmJEL classification –O13,J43,C33The comments of Honghua Chen,Guifeng Liu and especially Xian Xin,Bozhong Su and the anonymous referee were helpful in the revision of this paper.Demand for oilin China’s agro-production327China Agricultural Economic ReviewVol.1No.3,2009pp.327-341q Emerald Group Publishing Limited1756-137XDOI 10.1108/17561370910958891research focusing on the“growth limit”of agricultural economy.There were two main popular points of view:on the one hand,researchers focused exclusively on the means of reducing agricultural oil consumption(Liang,1987;Xia,1987;Gan,1992;Fan and Wang,2006);and on the other hand,scholars investigated the oil-dependency of agriculture.They analyzed the structure of agricultural input in view of energy,and they concentrated on the ratio of energy output-input of a specific area and crop (Cleveland,1995;Thakur and Makan,1997;Burhan et al.,2004;Inbrahin et al.,2005). Researchers made energy conversion based on various crop production and specific areas to analyze energy consumption and the efficiency of energy in agricultural production.They found that agricultural production depended on oil in various channels(Burhan et al.,2004;Wen,1985;Li et al.,1989;Chen,1991).In the twenty-first century,oil pricefluctuated remarkably and kept at a high level for a long period.Diesel prices in China increased many times with the world oil price soaring.The oil price rising had great negative impacts on economic development (Steven and John,2001;Arjaree and Subhes,2005;Li,1993;Yu et al.,2002;Chen,2005).Similarly,it induced negative effects on agricultural production and farmers’living standards.There is a long-run co-integration relationship between oil and diesel price (Wang and Tian,2007).At the same time,diesel is the direct channel in which agricultural production consumes oil.Faced with world oil price soaring,rational farmers should reduce the quantity of petroleum products consumption.But,there is still an obvious growing trend in the demand for farm diesel,chemical fertilizer, agriculture plastics and other oil products in Chinese agricultural production.Oil price soaring does not lead to a corresponding reduction in farm diesel consumption;in other words,the demand for diesel in agricultural production shows a growth characteristic with the oil price shocks(Figure1).Nonetheless,there is not a clear interpretation for the reasons why the demand for farm diesel keeps on growing while the oil price rises sharply at home and abroad.This paper aims to assess the essential reasons for this issue from theoretical and empirical perspectives.To explore these issues in more detail,this paper is based on the theory ofFigure1.Diesel prices(P)and the quantity of agricultural diesel consumption(Q)1,5002,0002,5003,0003,5004,0004,500Source: China Agricultural Statistical Yearbook (1994-2006);

E 1 and E 2 are the equilibrium points before and after the oil price changes; in this process, the equilibrium price rises from P 1 to P 2, the equilibrium quantity rises from Q 1 to Q 2Demand for oilin China’s agro-production329diesel consumption,the results suggest that there is a positive correlation between the diesel consumption and the comprehensive agricultural mechanization level[1].Therefore,agricultural diesel consumption per hectare and the agricultural mechanization level have the same changing trend.Table I reflects the relationships between China’s agricultural diesel consumption and agricultural machinery operating level in 2006.It indicates that the higher the level of machinery operating,the more diesel consumption per hectare.Furthermore,it has a fixed proportion coefficient between farm machinery usage and agricultural diesel consumption.How much diesel will be consumed by agricultural machinery operating per hectare,is a complex technical issue which depends on the performance of operating machinery,the conditions of agricultural machinery operating and the level of operation according to the principles of agricultural machinery operating.Along with the agricultural machinery manufacturing development,machinery performance is constantly improved,and the consumption of engine fuel has a downward trend,but the reduced quantity is soRegions Diesel consumption per hectare (kg/hectares)Level of machinery operating (%)Beijing 321.0046.41Tianjin 299.8658.86Hebei 573.1057.19Shanxi258.9137.87Iner Mongolia 148.7556.54Liaoning 230.9748.93Jilin204.6329.60Heilongjiang 132.1180.44Shanghai 260.5939.19Jiangsu 195.7160.08Zhejiang 328.4728.79Anhui 126.8747.56Fujian 288.6814.08Jiangxi 173.4935.93Shandong 796.8758.30Henan 186.5553.74Hubei 200.7426.07Hunan157.2127.66Guangdong 147.8221.53Guangxi 149.9610.76Hainan 161.3513.90Chongqing 95.8810.01Sichuan 116.3410.62Guizhou 68.32 3.01Yunnan 77.20 4.27Xizang ––Shanxi 157.4033.79Gansu 227.4423.88Qinghai 177.8341.29Ningxia 226.8536.75Xinjiang106.2970.60Source:China Statistical Year Book (2007)Table I.The level of machinery operating and diesel consumption per hectare (2006)CAER 1,3330small that the diesel consumption of agricultural machinery operating per hectare is almost stable in long run.There are several other economic variables that play an important role in the rigid growth characteristic of the demand for agricultural diesel,such as the market prices of agricultural products,prices and quantity of related input factors,and so on (Figure 3).Assume that there are only agricultural labor force (L )and agricultural machinery inputs (M )in agricultural production.Outputs (y )is a function of labor and machinery,written as y ¼f (L ,M ).According to the fixed proportion between the operations of agricultural machinery (M )and the volume of agricultural diesel consumption (Z ),the relationship between the two variables is expressed as the function Z ¼g (M ),it is strictly increasing,and meets the first order homogeneity,hence,its inverse function can be written as M ¼g 21ðZ Þ,and the agricultural production function can be written as follows:y ¼f L ;g 21ðZ ÞÀÁ:ð1ÞFormula (1)expresses the compound relationships between the agricultural production and input of farm diesel.Assume the agricultural production cost function is:c P L ;P M ;y ÀÁ¼min P L £L þP M £M ð2Þwhere P L is the wage of agricultural labor,and P M is the price of agriculturalmachinery.Formula (2)is continuous and strictly increasing,and meets all of the properties of the cost function.As we all know that the agricultural machinery operations costs include the charge of diesel consumption and the relation of the diesel price,and the price of agricultural machinery operations can be defined as follows:Figure 3.Demand curve foragricultural diesel,takingagricultural products price,agricultural labor and their wages intoaccountP ZZP Z 2P Z 1E 1D 0(L 0,p 0,P L 0)D 2(L 1 ,p 1,P L 1)Notes: P z and Z are the price and volume of agricultural diesel, L is the agricultural labor, p is the agricultural products price, D is agricultural diesel demand curve;

In this paper,the authors analyze the unilateral substitution of agricultural labor and mechanical from the perspective of changes in relative price,based on the hypothesis of the induced technological innovation developed by Hicks-Hayami-Vernon.The hypothesis states that agricultural technological progress is a dynamic reflection of the changes in the resource endowment and the growth in demand. Technological progress will promote the more abundant and relatively cheaper factor used in production,and as a result,the relative scarcity factor will be substituted. In agricultural production,changes in price of factors lead to machinery substitution for labor(or the reverse),and the speed and scale of the substitution depends on the ratio of agricultural machinery operating cost and the wages of the agricultural labor[2].The wage of Chinese agricultural labor is increasing with economic development and the cost of agricultural machinery manufacture is decreasing with technological progress.Taking the situations in2005and1988for example,the nominal wage of rural labor force in China in2005is nearly four times as much as that of in1988.The agricultural products price index in2005is2.77times as much as that of in1988,the machinery operation price index increased by1.15times,and the chemical fertilizer price index increased by1.65times.The ratio of the relative marginal products between labor and land is the most important index for representing the rises of the relative price of the agricultural labor force.In the production process,the relative price of the two factors is equal to their relative marginal products.According to the concept of the marginal products,wefind that the labor employment per hectare is the marginal product of labor(Table II). Comparing the labor employment per hectare of China’s staple crops production in 1995-2005,it can be found that there is a great decline in labor employment in national staple crops production.It indicates that the agricultural labor price is on the rise in China.Along with economic development,the migrant farmer workers increase continuously and the level of wages of the farmer workers in the city rise,whichDemand for oilin China’s agro-production333leads to an increase in the shadow wage of agricultural labors,and the scarcity of the effective agricultural labor force will emerge.Since most migrant farmer workers are engaged in the labor-intensive and relatively low-technology sectors,such as manufacturing and construction,the authors contrast the wages of workers engaged in various sectors to reflect the shadow wage of the agricultural labor (Table III).We can get the wages of migrant farmer workers from existing studies.Taking Shandong Province for example,the average net income per capita of farmers in 1994is 1,320Yuan,that is,their monthly net income per capita is 110Yuan.The average annual wage of workers in Shandong Province is 4,338Yuan,or monthly average wage per capita is 362Yuan (Li,2003).The wages of migrant farmer workers in China,mainly concentrate between 400and 800Yuan,accounting for 40percent of the investigated people;the number of migrant farmer workers whose monthly wages are 800-1,000Yuan,accounts for 12.6percent of the total number of investigated people (Li,2007).A large number of rural laborers are entering into industry and the services sectors due to rapid economic developments and the soaring of the relative price of agricultural labor.The amount of the labor force in agriculture,forestry,animal husbandry and fishery in China has had a downward trend since the 1980s (Table IV),and there has been an accelerated one since 2000.Year Paddy Wheat Maize Oil plants Corn

scarcer day by day with the rising of the relative price of agricultural labor.Alternative technology is needed to eliminate a choking point of agriculture development.In view of economic development and technological progress,agriculture mechanization is the direction of modern agriculture development.It is an inevitable tendency of input structural change that machinery replaces labor in agricultural production.The authors analyze the substitutive relationship between labor and machinery,including wheat,maize,cotton,paddy and oil plants in 1990-2006.The results show that there is a strictly negative correlation between agricultural machinery operations and labor force in the production process of the staple agricultural products,that is to say,there is a substitution between the two variables (Table V).3.Empirical models and dataChanges in the relative price of labor and machinery lead to the changes in the proportion of input factors,which means that the cost curve c ðP L ;P

production function,this paper measures the elasticity of substitution for input factors,and analyzes the substitution ability of machinery and labor,in order to explore the reasons for the rigid growth characteristic of the demand for diesel in agricultural production.Production function has been developed from the Cobb-Douglas production function to translog production function and three-level CES production function since 1928(Li,1992;Chen and Chen,1993).In the field of agricultural production research,the production function is mainly used to measure the contribution rate of the factors input to the agricultural products output,output elasticity and the impact of technological progress on agricultural production (Lin,1994;Wang and Wu,2006).This paper loosens the presumption of “the unitary elasticity of agricultural production input factors,”adopts the two-level CES production function which assumes that the substitution elasticity of machinery for labor,fertilizer for other substances are different,and develops the two level CES wheat production function.The first-level equations of the two-level CES agricultural production function are given as follows:Y ML ¼Àa 1M 2r 1þÀ12a 1ÁL 2r 1Á2ð1=r 1Þð9ÞY FA ¼Àa 2F 2r 2þÀ12a 2ÁA 2r 2Á2ð1=r 2Þð10Þwhere L is labor,M is machinery,F is fertilizer and A is other input materials,Yis the crop output,Y ML is the aggregate labor input,Y FA is the aggregate land input,a i is the distribution coefficient,and r I is the substitution coefficient,0,a i ,1;21,r i ,1.The crop yield (Y )can be expressed as follows:Y ¼B bY 2r ML þð12b ÞY 2r FA ÀÁ2ðm =r Þð11Þwhere B is the effective coefficient,b is the distribution coefficient,and r i is thesubstitution coefficient.There are two approaches to estimate the two-level CES production function (Li,1992),one is indirect estimation by using the marginal productivity of the conditions for yield maximization.Hayami (2000)used this method to estimate agricultural production of all countries in the world.The shortcomings of this method are the strict assumptions,which are far away from reality in most cases.The other method is to unwrap the two-level CES production function using Taylor series,and to linearize production function by substitute variables,finally,estimating directly by OLS,the data available,and its assumptions are also relatively wide,thus this method is more practical.Since there is the similar characteristic of machinery substitution for labor among wheat,maize,paddy,cotton,oil plants as well as other staple crop production process,the substitution of machinery and labor of wheat production is therefore in the middle level,and its historical data are relatively complete.This paper thus chooses wheat production function as representation.The variables in the model include wheat yield per hectare and per hectare of the input factors,including labor,machinery and chemical fertilizers.Data are from “the Compilation of China’s agricultural products cost-benefit”(1989-2006),and the price index is from the Price Yearbook in China (1989-2006).CAER 1,3336Since there is significant difference in climates and soil conditions among the various provinces and cities as well as the autonomous regions,the wheat planted acreage in various provinces in2005show that Henan and Shandong provinces are wheat-producing provinces.However,the wheat planted acreages are very small in Hainan,Fujian,Guangdong,Jilin,Guangxi,Jiangxi,Liaoning,Shanghai.The growth of wheat yield depends on the machinery technology advancement(Wang and Wu,2006). Therefore,if we miss the provinces’data whose agricultural mechanization level is low, the impacts on the empirical results would be little.According to that idea,this paper includes21provinces with355of the data.The authors deal with the previous data of the agricultural production price index based on the1988price to eliminate the inflation of the cost of fertilizers,agricultural machinery operating and other material factors.4.Estimated results and discussionThe specific estimated results are expressed in Table VI.The estimated results from Model1to Model3used data from1988-2005,1988-1996,1997-2005separately.The results suggest that there is a goodfitting of the model;adjusted R2equals0.99,and within the inspected variables,the parameters in the model are consistent with the expectation,and the coefficients are with statistical significance[3].According to the results of Model1,we can get the distribution coefficient and substitution coefficient,and hence we can write the estimated equations as follows:^Y ML ¼0:54M20:21þ0:46L20:21ÀÁ2ð1=0:21Þð12Þ^Y FA ¼0:29F22:07þ0:71A20:27ÀÁ2ð1=2:07Þð13Þ^Y¼33:470:79Y20:23ML þ0:21Y20:23FA2ð0:69=0:23Þð14Þwhere^Y ML;^Y FA;^Y are the estimated values.Formulae(12)and(13)are the estimated first-level CES production function.According to the properties of the two-level CESVariablesModel1Model2Model3Coefficients t-value Coefficients t-value Coefficients t-valueLog L0.11 4.270.15 6.560.05 2.44 Log F0.3912.010.39 5.460.4110.92 Log M0.09 6.620.12 3.980.09 6.60 Log A0.10 4.330.040.490.10 3.99 log(M/L)20.01 2.700.01 2.410.01 2.53 log(F/A)20.089.080.08 1.730.088.92 log(F/L)20.02 1.36––––DI20.3526.2920.5325.6320.2724.43 C 3.5139.93 3.6127.93 3.6232.62Adjusted R20.990.990.99Effective sample355176179Notes:The authors have made a serial correlation test.The results show that the residual models are not auto-correlationTable VI.
