你有什么天赋的英语作文
In the vast expanse of human abilities, there exists a unique attribute that sets individuals apart from one anothertalent. When it comes to the English language, some individuals possess an innate aptitude that enables them to excel in various aspects of the language, from speaking and writing to understanding complex linguistic structures. This essay will delve into the concept of innate talent in English and explore how it manifests in different individuals.Firstly, it is essential to recognize that talent in English is not a monolithic concept. It can manifest in various forms. For some, it is the ability to articulate thoughts with eloquence and precision, while for others, it might be the capacity to grasp the nuances of the language quickly. Some individuals may have a natural flair for writing, crafting sentences that are both engaging and informative. Others might excel in listening and understanding spoken English, even when it is delivered at a rapid pace or with a heavy accent.One of the most apparent forms of English talent is linguistic intuition. This refers to the ability to understand and use the language correctly without having to consciously apply grammatical rules. Such individuals often find it easier to pick up new vocabulary and idiomatic expressions, making them adept at adapting to different dialects and styles of English.Another aspect of English talent is the capacity for creativity in language use. This is particularly evident in those who excel in writing. They can weave words together to create vivid imagery, compelling narratives, and persuasive arguments. Their writing not only conveys information but also engages the reader on an emotional level, making their work memorable and impactful.Moreover, talented English speakers often exhibit exceptional communication skills. They can express their thoughts clearly and concisely, making them effective in both formal and informal settings. This ability to communicate effectively is crucial in various professional and social contexts, where the ability to articulate ideas and persuade others can be a significant advantage.It is also worth noting that talent in English is not solely about native speakers. Many nonnative speakers demonstrate remarkable proficiency and mastery of the language. Their dedication to learning and understanding English, coupled with their natural aptitude, allows them to achieve high levels of fluency and accuracy.However, it is important to acknowledge that talent alone is not enough to guarantee success in mastering English. It must be complemented by hard work, practice, and acontinuous desire to improve. Talent can provide a head start, but it is the commitment to learning and refining ones skills that ultimately leads to mastery.In conclusion, the talent for English is a multifaceted gift that can manifest in various ways, from linguistic intuition to creative writing and effective communication. While it can provide an advantage, it is the combination of talent and dedication that truly sets apart those who excel in the English language. Recognizing and nurturing this talent, whether in oneself or in others, can lead to a deeper appreciation and mastery of the rich and diverse world of English.。
ARTHUR_1999_Complexity_and_the_economy
Complexity and the EconomyW. Brian ArthurCitibank Professor, Santa Fe InstitutePaper appeared in Science,2 April 1999, 284, 107-109Common to all studies on complexity are systems with multiple elements adapting or reacting to the pat-tern these elements create. The elements might be cells in a cellular automaton, or ions in a spin glass, or cells in an immune system, and they may react to neighbor-ing cells’ states, or local magnetic moments, or concen-trations of B and T cells—“elements” and the “patterns”they respond to vary from one context to another. But the elements adapt to the world—the aggregate pat-tern—they co-create. Time enters naturally here via ad-justment and change: as the elements react, the aggre-gate changes, as the aggregate changes, elements react anew. Barring some asymptotic state or equilibrium reached, complex systems are systems in process, sys-tems that constantly evolve and unfold over time.Such systems arise naturally in the economy. Eco-nomic agents, be they banks, consumers, firms, or in-vestors, continually adjust their market moves, buying decisions, prices, and forecasts to the situation these moves or decisions or prices or forecasts together create. But unlike ions in a spin glass which always react in a simple way to their local magnetic field, economic “elements”—human agents—react with strategy and foresight by considering outcomes that might result as a consequence of behavior they might undertake. This adds a layer of complication to economics not experi-enced in the natural sciences.Conventional economic theory chooses not to study the unfolding of the patterns its agents create, but rather to simplify its questions in order to seek analytical so-lutions. Thus it asks what behavioral elements (actions, strategies, expectations) are consistent with the aggre-gate patterns these behavioral elements co-create? For example, general equilibrium theory asks: what prices and quantities of goods produced and consumed are con-sistent with—would pose no incentives for change to—the overall pattern of prices and quantities in theeconomy’s markets. Game theory asks: what strategies, moves, or allocations are consistent with—would in-duce no further reactions to—the potential outcomes these strategies, moves, allocations might imply. Ra-tional expectations economics asks: what forecasts (or expectations) are consistent with—are on average vali-dated by—the outcomes these forecasts and expectations together create. Conventional economics thus studies consistent patterns—patterns in behavioral equilibrium, patterns that would induce no further reaction. Econo-mists at the Santa Fe Institute, Stanford, MIT, Chi-cago, and other institutions, are now broadening this equilibrium approach by turning to the question of how actions, strategies, or expectations might react in gen-eral to—might endogenously change with—the aggre-gate patterns these create [1]. The result, complexity economics, is not an adjunct to standard economic the-ory, but theory at a more general, out-of-equilibrium level.The type of systems I have described become espe-cially interesting if they contain nonlinearities in the form of positive feedbacks. In economics positive feed-backs arise from increasing returns [2] [3]. To ensure a unique, predictable equilibrium is reached, standard eco-nomics usually assumes diminishing returns. If one firm gets too far ahead in the market, it runs into higher costs or some other negative feedback and the market is shared at a predictable, unique equilibrium. When we allow positive feedbacks, or increasing returns, a differ-ent outcome arises. Consider the market for online serv-ices of a few years back, in which three major compa-nies competed: Prodigy, Compuserve, and America On-line. As each gained in membership base it could offer a wider menu of services as well as more members to share specialized hobby and chatroom interests with—there were increasing returns to expanding the membership base. Prodigy was first in the market, but1by chance and strategy American Online got far enough ahead to gain an unassailable advantage. Today it domi-nates. Under different circumstances, another rival might have taken the market. Notice the properties here: a multiplicity of potential “solutions”; the outcome actu-ally reached is not predictable in advance; it tends to be locked in; it is not necessarily the most efficient eco-nomically; it is subject to the historical path taken; while the companies may start equal, the outcome is asymmetrical. These properties have counterparts in non-linear physics where similar positive feedbacks are present. What economists call multiple equilibria, non-predictability, lock-in, inefficiency, historical path de-pendence, and asymmetry; physicists call multiple meta-stable states, unpredictability, phase- or mode-locking, high-energy ground states, non-ergodicity, and symmetry breaking [3].Increasing returns problems have been discussed in economics for a long time. A hundred years ago, Alfred Marshall [5] noted that if firms gain advantage as their market share increases, “whatever firm first gets a good start will obtain a monopoly.” But the conventional, static equilibrium approach gets stymied by indetermi-nacy: If there is a multiplicity of equilibria, how might one be reached? The process-oriented, complexity ap-proach suggests a way to deal with this. In the actual economy, “small random events” happen—in the on-line-services case “random” interface improvements, new offerings, word-of-mouth recommendations. Over time increasing returns magnifies the cumulation of such events to “select” the outcome randomly. Thus increasing returns problems in economics are best seen as dynamic processes with random events and natural positive feedbacks—as nonlinear stochastic processes. This shift from a static outlook into a process orienta-tion is common to complexity studies. Increasing re-turns problems are being studied intensively in market allocation theory [3], international trade theory [6], the evolution of technology choice [7], economic geogra-phy [8], and the evolution of patterns of poverty and segregation [9]. The common finding that economic structures can crystallize around small events and lock in is beginning to change policy in all these areas to-ward an awareness that governments should avoid both extremes of coercing a desired outcome or keeping strict hands off, and instead seek to push the system gently toward favored structures that can grow and emerge natu-rally. Not a heavy hand, not an invisible hand, but a nudging hand.Once we adopt the complexity outlook, with its em-phasis on the formation of structures rather than their given existence, problems involving prediction in the economy look different. The conventional approach asks what forecasting model (or expectations) in a particular problem, if given and shared by all agents, would be consistent with—would be on average validated by—the actual time series this forecasting model would in part generate. This “rational expectations” approach is valid.But it assumes that agents can somehow deduce in ad-vance what model will work, and that everyone “knows”that everyone knows to use this model (the common knowledge assumption.) What happens when forecast-ing models are not obvious and must be formed indi-vidually by agents who are not privy to the expectations of others?Consider as an example my El Farol Bar Problem[10]. One hundred people must decide independentlyeach week whether to show up at their favorite bar (El Farol in Santa Fe). The rule is that if a person predicts that more that 60 (say) will attend, he will avoid the crowds and stay home; if he predicts fewer than 60 he will go. Of interest are how the bar-goers each week might predict the numbers showing up, and the result-ing dynamics of the numbers attending. Notice two features of this problem. Our agents will quickly realize that predictions of how many will attend depend on oth-ers’ predictions of how many attend (because that deter-mines their attendance). But others’ predictions in turn depend on their predictions of others’ predictions. De-ductively there is an infinite regress. No “correct” expec-tational model can be assumed to be common knowl-edge, and from the agents’ viewpoint, the problem is ill-defined. (This is true for most expectational prob-lems, not just for this example.) Second, and diaboli-cally, any commonalty of expectations gets broken up: If all use an expectational model that predicts few will go, all will go, invalidating that model. Similarly, if all believe most will go, nobody will go, invalidating that belief. Expectations will be forced to differ.In 1993 I modeled this situation by assuming that as the agents visit the bar, they act inductively—they act as statisticians, each starting with a variety of subjec-tively chosen expectational models or forecasting hy-potheses. Each week they act on their currently most23accurate model (call this their active predictor). Thus agents’ beliefs or hypotheses compete for use in an ecology these beliefs create. Computer simulation (Fig.1) showed that the mean attendance quickly converges to 60. In fact, the predictors self-organize into an equilib-rium “ecology” in which of the active predictors 40%on average are forecasting above 60, 60% below 60.This emergent ecology is organic in nature. For, while the population of active predictors splits into this 60/40average ratio, it keeps changing in membership forever.Why do the predictors self-organize so that 60 emerges as average attendance and forecasts split into a 60/40ratio? Well, suppose 70% of predictors forecasted above 60 for a longish time, then on average only 30 people would show up. But this would validate predictors that forecasted close to 30, restoring the “ecological” balance among predictions. The 40%–60% “natural” combina-tion becomes an emergent structure. The Bar Problem is a miniature expectational economy, with complex dy-namics. [11].0102030405060708090100020406080100TimeFigure 1. Bar Attendance in the first 100 Weeks.One important application of these ideas is in finan-cial markets. Standard theories of financial markets assume rational expectations—that agents’ adopt uni-form forecasting models that are on average validated by the prices these forecast [12]. The theory works well to first order. But it doesn’t account for actual market “anomalies” such as unexpected price bubbles and crashes, random periods of high and low volatility (price variation), and the heavy use of technical trading (trades based on the recent history of price patterns).Holland, LeBaron, Palmer, and I [13] have created a model which relaxes rational expectations by assum-ing, as in the Bar Problem, that investors cannot as-sume or deduce expectations but must discover them.Our agents continually create and use multiple "market hypotheses"—individual, subjective, expectational models—of future prices and dividends within an artifi-cial stock market on the computer. These “investors”are individual, artificially-intelligent computer pro-grams that can generate and discard expectational “hy-potheses,” and make bids or offers based on their cur-rently most accurate hypothesis. The stock price forms from their bids and offers, and thus ultimately from agents’ expectations. So this market-in-the-machine is its own self-contained, artificial financial world. Like the bar, it is a “mini-ecology” in which expectationscompete in a world these expectations create.Within this computerized market, we found two phases or regimes. If parameters are set so that our artificial agents update their hypotheses slowly, the diversity of expectations collapses quickly into homo-geneous rational expectations ones. The reason is that if a majority of investors believes something close to the rational expectations forecast, then resulting prices will validate it, and deviant or mutant predictions that arise in the population of expectational models will be rendered inaccurate. Standard finance theory, under these special circumstances, is upheld. But if the rate of up-dating of hypotheses is turned up, the market under-goes a phase transition into a “complex regime” and displays several of the “anomalies” observed in real markets. It develops a rich “psychology” of divergent beliefs that don’t converge over time. Expectational rules such as “If the market is trending up, predict a 1% price rise” that appear randomly in the population of hypotheses can become mutually reinforcing—if enough investors act on these, the price will indeed go up. Thus sub-populations of mutually reinforcing ex-pectations arise, agents bet on these (therefore technical trading emerges) and this causes occasional bubbles and crashes. Our artificial market also shows periods of high volatility in prices followed randomly by periods of low volatility. This is because if some investors “discover” new, profitable hypotheses, they change the market slightly, causing other investors to also change their expectations. Changes in beliefs therefore ripple through the market in avalanches of all sizes, causing periods of high and low volatility. We conjecture that actual financial markets, which show exactly these phenomena, lie in this “complex” regime. ConclusionAfter two centuries of studying equilibria—static patterns that call for no further behavioral adjust-ments—economists are beginning to study the general emergence of structures and unfolding of patterns in the economy. Complexity economics is not a temporary adjunct to static economic theory, but theory at a more general, out-of-equilibrium level. The approach is mak-ing itself felt in every area of economics: game theory [14], the theory of money and finance [15], learning inthe economy [16], economic history [17], the evolu-tion of trading networks [18], the stability of the econ-omy [19], and political economy [20]. It is helping us understand phenomena such as market instability, the emergence of monopolies, and the persistence of pov-erty in ways that will help us deal with these. And it is bringing an awareness that policies succeed better by influencing the natural processes of formation of eco-nomic structures, than by forcing static outcomes.When viewed in out-of-equilibrium formation, eco-nomic patterns sometimes simplify into the simple, homogeneous equilibria of standard economics. More often they are ever-changing, showing perpetually novel behavior and emergent phenomena. Complexity therefore portrays the economy not as deterministic, predictable and mechanistic; but as process-dependent, organic and always evolving.References and Notes1.

Part II Reading Comprehension (Skimming and Scanning)(15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quickly. For questions 1-7, choose the best answer from the four choices marked A), B), C) and D). For questions 8-10, complete the sentences with the information given in the passage.DepressionDepression is a common type of mental disorder — most people will be affected by depression in their lives either directly or indirectly. Confusion about depression is commonplace: for example, about what depression is and what makes it different from just feeling down. There is also confusion surrounding the many types of depression that people may experience. There have been so many terms used to describe this set of feelings we’ve all felt at one time or another in our lives, to one degree or another, that it is time to set the record straight.1. Types of DepressionDepressive disorders come in different forms, just as other illnesses such as heart disease. This passage briefly describes three of the most common types of depressive disorders. However, within these types there are variations in the number of symptoms, their severity, and persistence.Major depression is manifested by a combination of symptoms that interfere with the ability to work, study, sleep, eat, and enjoy once pleasurable activities. Such a disabling episode of depression may occur only once but more commonly occurs several times in a lifetime.A less severe type of depression, dysthymia, involves long-term, chronic symptoms that do not disable, but keep one from functioning well or from feeling good. Many people with dysthymia also experience major depressive episodes at some time in their lives.Another type of depression is bipolar disorder, which is characterized by cycling mood changes: severe highs (mania) and lows (depression). Sometimes the mood switches are dramatic and rapid, but most often they are gradual. When in the depressed cycle, an individual can have any or all of the symptoms of a depressive disorder. When in the manic cycle, the individual may be overactive, over-talkative, and have agreat deal of energy. Mania often affects thinking, judgment, and social behavior in ways that cause seriousproblems and embarrassment. For example, the individual in a manic phase may feel elated and full of grandschemes that might range from unwise business decisions to romantic sprees.2. Symptoms of DepressionDepression is characterized by a number of common symptoms. Not everyone who is depressed or manic experiences every symptom. Some people experience a few symptoms, some many. Severity of symptoms varies with individuals and also varies over time.●Persistent sad, anxious, or “empty”mood●Feelings of hopelessness, pessimism●Feelings of guilt, worthlessness, helplessness●Loss of interest or pleasure in hobbies and activities that were once enjoyed●Decreased energy, fatigue, being “slowed down”●Difficulty concentrating, remembering, or making decisions●Insomnia, early-morning awakening, or oversleeping●Appetite and/or weight loss or overeating and weight gain●Thoughts of death or suicide; suicide attempts●Restlessness, irritability●Persistent physical symptoms that do not respond to treatment, such as headaches, digestive disorders and chronic pain3. Risk Factors of DepressionWhile depression can strike anyone at any time, research has identified several factors associated with an increased risk for depression:Family History — Having an immediate family member with depression increases the risk of developing depression. Other mental illnesses, such as alcoholism in family members, can also increase the risk for depression.Early Childhood Experience — Early childhood trauma, such as loss of a parent before adolescence, child neglect, physical, emotional abuse, and parental divorce are all linked to increased risk for adult depression.Stress — Negative life events, such as divorce, loss of a loved one or loss of employment are associated with increased depression. Research shows that chronic stresses (such as illness, lack of social support and numerous “daily hassles”) are also linked to depression.Alcohol — Depression and alcoholism is often seen in the same patients at the same time. Alcohol is a depressant drug and its presence in a depressed person has serious implications for treatment outcome.Residence — Depression seems to be higher in urban residents than in rural residents. In fact, one study found that depression was twice as common among city dwellers as among those who lived in rural areas.Marital Status — Depression is highest among divorced, separated, or co-habitating people. It is lowest among single and married people. People living alone have higher rates of depression than those living with others do.Work Status — Research shows that people unemployed for six months or more in the last five years had a rate of depression three times that of the general population.Physical Illness — Certain physical illnesses are associated with depression, such as thyroid disorder, hormonal imbalances, chronic viral infections, cancer and heart diseases.Gender — It is estimated that one out of every four women and one out of every ten men experience some type of depression during their lifetime. While women suffer from depression more often and attempt suicide more frequently, men are more successful in their suicide attempts. Women also suffer from unique forms of depression related to their unique biology and life experiences.Age — Most people experience their first episode of depression between the ages of 20 and 40. In fact, the average age of onset of depression is the mid-20s. Alarmingly, recent research shows that the average age of onset is decreasing with each generation. Children, adolescents and elderly persons often display unique symptoms of depression and have specific stressful events that predispose them to depression.Ethnic and cultural groups — The World Health Organization named depression the fourth most devastating illness in the world today and predicted that it would become the second ranked illness by 2020. No ethnic or cultural group is immune. While depression occurs at about the same rate in different groups, ethnic and cultural differences often impact the ways in which their members express their feelings and their willingness to seek treatment.Tobacco — Increased tobacco use has been noted in depressed persons and individuals with underlying or current depressive symptoms are likely to experience mood disturbances when they attempt to quit.4. Treatments for DepressionFortunately, there are many effective treatment options for depression. To be most effective, treatment should be specifically tailored to each individual. That is why a detailed interview by a mental health professional is extremely valuable. Established treatments for depression may include:●antidepressant medications●psychotherapy (also known as “talk therapy”or “counseling”)All of these treatments have been shown to treat depression successfully. The choice of treatment will be determined by several factors, including the type and severity of depression, by previous treatment history, and patient preference. A combination of medications and psychotherapy is used to treat most patients, although mild forms of depression may be treated with psychotherapy alone.Effective treatment is based on an accurate assessment, which identifies the causes of depression in any person. Usually depression is a result of biological, psychological and social factors, and an effective treatment plan is one that identifies all of these and develops strategies to reduce their frequency and intensity.1.

It is believed that the water is 47 at the poles and possibly formed by the solar wind. The finding was made after researchers examined data from three separate 48 to the moon. The reports show that the water may be moving around, forming and reforming as particles become 49 up in the dust on the surface of the moon.Dr. Mylswamy Annadurai, the mission’s project director at the Indian Space Research Organisation in Bangalore, told The Times, “It’s very 50 . This was one of the main objectives of Chandrayaan-1, to find evidence of water on the moon.” The unmanned craft was 51 with NASA’s Moon Mineralogy Mapper (美国航天局设计的月球矿物绘图仪,简称M3), designed 52 to search for water by picking up the electromagnetic radiation sent out by minerals. The M3 was designed to search for water by 53 the electromagnetic radiation given off by different minerals on and just below the surface of the moon. Unlike previous equipment, it was 54 enough to detect the existence of small amounts of water.Carle Pieters of Brown University in Rhode Island and his colleagues 55 data from Chandrayaan-1 and found spectrographic (光谱的) evidence of water. The water seems thicker closer to the poles, they reported. “When we say ‘water on the moon’, we are not talking about lakes or oceans. Water on the moon means molecules of water and hydroxyl (hydrogen and oxygen) that 56 with molecules of rock and dust specifically in the top millimeters of the moon’s surface,” Pieters said in a statement. Scientists said the breakthrough would change the face of lunar exploration.A) specifically I) concentratedB) detecting J) sensitiveC) occasionally K) reviewedD) decisions L) satisfyingE) missions M) dividedF) interact N) equippedG) disappointing O) mixedH) sensible■Section BDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished sentences. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice.Passage OneQuestions 57 to 61 are based on the following passage.Feeding 30 million schoolchildren is a difficult task. As a result, many of today’s school cafeteria offerings end up as appealing as a tray of lukewarm airplane food. And if there’s one point of agreement on the state of school lunches, it’s that local school districts and the federal government are over-tasked. The U.S. Department of Agriculture’s National School Lunch Program (NSLP) helps feed millions of American schoolchildren. Critics charge that the program is under-funded and misspends money on meals that are overly processed, too rich in fat and not nutritious. The challenge is how to change this on a national and local level.Help has historically trickled in courtesy of local entrepreneurs and nearby natural-food advocates who supplied some schools with organic and farm-fresh foods. Now, a new campaign supported by national corporations hopes to make more sweeping changes across the country. Whole Foods and a loose coalition of organic-food manufacturers and advocates say that creating a healthier national food policy is the start. Last August, Whole Foods launched a fund-raising campaign to reform the country’s school lunch programs and has so far raised more than $440,000 that will support an online effort to help school districts create healthy and affordable meal options. According to the supermarket chain’s chief operating officer Walter Robb, some of that money will also help raise awareness about the Child Nutrition Act (CAN).CAN determines school food policy and financial resources as well as funds the NSLP. Advocates for healthier lunches say that the Nutrition Act will be reauthorized by the president and Congress. School lunch programs now get $9.3 billion in federal funding, or about $2.68 for each eligible child. Subtract labor and other administrative costs and some child-nutrition advocates estimate that only $1 goes toward food. That’s not enough, said Robb. “It’s a Sisyphean situation. We’re at a tipping point. We need to raise exposure and do something right now.”For Ann Cooper, the former director of nutrition services for California’s Berkley Unified School District, help from either the public or private sector is much needed. Cooper, a chef and author, created , funded b y Whole Foods. The site’s mission is “to help your community transition step by step to a school program that will improve the health and well-being of our children”. It features recipes for schools, information about food safety, and promotes community ac tivism. “I hope we’re building a trend,” Cooper said of her partnership with Whole Foods. “More companies are doing this. Maybe it’s part altruistic, part capitalistic. But if a company can make money feeding kids and make them healthier, that’s the bottomline.”57. From the first paragraph, what can we learn about today’s school cafeteria offerings?A) They are good but not adequate.B) They are not healthy enough.C) They are rich in fat and protein.D) They are the same as those on airplanes.58. The u nderlined word “coalition” in the second paragraph means “_________”.A) a union of two political partiesB) a combination of different partsC) a group of people who join togetherD) a kind of movement59. The money raised by Whole Foods will be primarily used to ____________.A) carry out school food policiesB) make people better aware of CANC) launch a campaign about healthy foodD) help school districts provide better food60. What does the underlined sentence “It’s a Sisyphean situation.” in the th ird paragraph mean?A) A situation that is satisfactory and should be maintained.B) A situation that hasn’t been changed much.C) A situation that is stable and should be improved gradually.D) A situation that is worse than before and cannot be changed.61. Which of the following descriptions of Ann Cooper is correct?A) She is a teacher at the Children’s Nutrition School.B) She has many recipes for delicious food.C) She created a website to help school lunch programs.D) She is a community volunteer helping children.Passage TwoQuestions 62 to 66 are based on the following passage.The UN has declared 2010 the International Year of Biodiversity. In October, scientists and politicians will meet in Japan to assess progress towards the targets under The Convention on Biological Diversity, confirmed at the 2002 Johannesburg summit in South Africa. The bad news is that the chances of meeting those targets are extremely low. Most indicators suggest that the rate of biodiversity loss is increasing, not slowing. It is clear that we need to redouble our efforts.This has to be done in two ways: by improving scientific understanding of what is happening to the world’s biodiversity, and by ensuring that this understanding is conveyed to as wide an audience as pos sible. Both are difficult but essential — and fortunately both are doable.On the first front, we need to know in as much detail as possible what has happened to biodiversity over the recent past (the 300 or so years since the revolutions in industrializat ion and agriculture had a major impact on the world) so we can better measure current rates of biodiversity loss. Only when we have a validated rate of past decline can we assess the effects of conservation efforts.We also need to be creative about where we look for that evidence. Monitoring programs show evidence of changes in one place over a few years or decades, but they are already being made more difficult by theimpact climate change is having on the distribution of organisms — and thus on biodiversity — at any particular place on the planet.When it comes to longer-term changes, monitoring clearly cannot help. This is where scientific collections such as those in natural history museums and herbaria can make a unique contribution. These vast, painstakingly assembled collections of animals and plants are more than mere relics: they offer snapshots of past biodiversity. The collections held in institutions like the Natural History Museum in London can make an important contribution by providing data that will help us all to assess long-term changes in biodiversity.But assessing the changes is clearly not enough on its own. Action to foster biodiversity is urgently needed, and that requires politicians — and thus the wider public — to understand the significance of the changes taking place. This can be a complex message to communicate. The issue is not whether it is worth conserving a charismatic mammal or whether it matters if a few nematodes become extinct: it needs to be far more widely understood that declines in individual species herald the decline of diversity in whole ecosystems, which, in turn, has implications for human survival.62. The conference to be held in Japan aims to _________.A) evaluate whether there has been any progress in protecting biodiversityB) set up targets for biological diversity all over the worldC) increase biodiversity through various efforts in South AfricaD) call people’s attention to the rate of biodiversity loss63. What greatly affected biological diversity over the recent past?A) Climate change.B) Man’s damage to the earth.C) The industrial and agricultural revolutions.D) Scientific research and progress.64. The scientific collections of animals and plants provide _________.A) great relics for visitors to appreciateB) snapshots to show historical eventsC) useful data to understand changes in biodiversityD) rare evidence to prove their previous existence65. Which of the following can best summarize the main idea of the passage?A) The International Year of Biodiversity focuses our attention on the study of biodiversity.B) Scientific ways should be used to slow down the rate of biodiversity loss.C) Changes in biodiversity may endanger the existence of human beings.D) The public should know more about the importance of biodiversity.66. What is implied in the passage?A) More efforts should be made to conserve biodiversity.B) Monitoring programs have proved to be ineffective.C) It is high time that we made efforts to foster biodiversity.D) Building museums is an important way to save biodiversity.Part V Cloze(15 minutes)Directions: There are 20 blanks in the following passage.

买东西选择困难症英语作文
As a high school student, Ive always been fascinated by the myriad of choices available in the modern world. From the latest gadgets to the most fashionable clothing, theres no shortage of options to choose from. However, this abundance of choice, while seemingly a blessing, has often led me to experience what is colloquially known as choice paralysis or analysis paralysis. Its a phenomenon where the sheer volume of options available makes it difficult to make a decision, and Ive found myself in the throes of this dilemma on numerous occasions.One such memorable experience occurred during a shopping trip with my friends. We were at a bustling shopping mall, and I was on the hunt for a new pair of sneakers. The store was a treasure trove of athletic footwear, with rows upon rows of different brands, colors, and styles. I felt a mix of excitement and anxiety as I scanned the shelves. The vibrant colors and sleek designs were alluring, but the decisionmaking process was daunting.As I stood there, I began to analyze each pair of sneakers. I considered factors such as comfort, durability, style, and price. I weighed the pros and cons of each option, trying to find the perfect balance. My friends, meanwhile, seemed to make their choices effortlessly. They would pick a pair, try them on, and decide within minutes. I couldnt help but feel envious of their decisiveness.The longer I spent in the store, the more overwhelmed I became. My mind was a whirlwind of thoughts, each pair of sneakers vying for my attention. I felt a growing sense of frustration as I realized that I was unable to make a decision. The fear of making the wrong choice or missing out on a betteroption was paralyzing.This experience is not unique to me. In fact, its a common issue faced by many consumers today. The concept of analysis paralysis has been studied by psychologists and marketers alike. Its been found that when presented with too many choices, people tend to experience decision fatigue, which can lead to dissatisfaction and regret, even if they eventually make a decision.To overcome this challenge, Ive learned to employ a few strategies. First, I try to narrow down my options by setting clear criteria for what Im looking for. This helps to eliminate choices that dont meet my specific needs or preferences. Second, Ive learned to trust my instincts. Sometimes, the first pair of sneakers that catches my eye is the one that feels right. Lastly, I remind myself that its okay to make a mistake. No decision is perfect, and its important to accept that there will always be tradeoffs.Moreover, Ive come to appreciate the value of simplicity in decisionmaking. In a world where we are constantly bombarded with choices, its refreshing to embrace the idea of minimalism. Whether its choosing between two favorite flavors of ice cream or deciding on a single outfit for the day, simplifying our options can lead to greater satisfaction and less stress.In conclusion, the experience of choice paralysis is a testament to the complexity of modern consumer culture. While its exciting to have a plethora of options at our fingertips, its also important to recognize the potential pitfalls of too much choice. By setting clear criteria, trusting ourinstincts, and embracing simplicity, we can navigate the decisionmaking process with greater ease and confidence. After all, the goal is not to have the most options, but to make the best choice for ourselves.。
剑桥雅思18 作文 test4
剑桥雅思18 作文 test4The Allure of the Unreachable: Why We Desire What We Cannot Have There's an undeniable allure to the things just beyond our grasp. Whether it's a coveted designer handbag, a job opportunity out of reach, or even a person we can't seemto get close to, the unattainable holds a peculiar power over our desires. This phenomenon, observed across cultures and throughout history, begs the question: why are we so drawn to what we cannot have? One explanation lies within the very nature of desire itself. As humans, we are wired to strive, to seek out challenge and novelty. The easily obtainable loses its luster quickly, fading into the background of the mundane. The unattainable, however, remains perpetually exciting, wrapped in an aura of mystery and possibility. It becomes an object of fascination, fueling our imaginations and keeping us engaged in a continuous pursuit. This chase is further intensified by the scarcity principle. We tend to value things more highly when they are perceived as rare or limited. The unattainable, by definition, falls into this category, automatically elevating its desirability. This principle is exploited in various aspects of life, from limited edition products to exclusive clubs, all playing on our innate desire for the unique and exceptional. The pursuit of the unattainable also taps into our inherent need for self-improvement. We often associate these elusive goals with personal growth and advancement. Achieving them becomes a symbol of success, a testament to our capabilities. The challenge itself is seen as an opportunity to learn, to push our boundaries, and ultimately, to become better versions of ourselves. However, the allure of the unattainable can be a double-edged sword. While it can serve as a powerful motivator, it can also lead to frustration and disappointment. The constant yearning for something just out of reach can leave us feeling unfulfilled and discontent with what we already possess. It's crucial to strike a balance, to appreciate the journey as much as the destination, and to recognize that true fulfillment comes not from external validation, but from within ourselves. Ultimately, the desire for the unattainable is a complex interplay of psychological, social, and even evolutionary factors. It's a testament to our inherent drive to explore, to challenge ourselves, and to constantly strive for something more. While this pursuit can be fraught with challenges, it is also afundamental part of the human experience, shaping our desires, motivating our actions, and ultimately, defining who we are.。
脑洞里的奇葩作文英语
脑洞里的奇葩作文英语Brainstorming is a wonderful thing. It allows us to think outside the box and come up with creative ideas. However, sometimes our ideas can be a little too out there. In this essay, I will be writing a wacky essay based on the prompt "What if the sun was made of cheese?"If the sun was made of cheese, it would be a dream come true for cheese lovers all around the world. Imagine being able to take a bite out of the sun whenever you wanted! Of course, there would be some downsides to this as well. For one, the sun would no longer be able to provide us with heat and light. Instead, it would just be a giant ball of cheese floating in space.But let's not focus on the negatives. Instead, let's explore the possibilities of a world where the sun is made of cheese. For starters, we would need to come up with a way to transport the cheese back to Earth. Maybe we could send a team of astronauts to the sun with giant cheeseknives and have them slice off chunks of cheese to bring back with them. Or, we could build a giant cheese-grater spaceship that could shred the sun into small pieces and transport them back to Earth.Once we had the cheese safely back on Earth, the possibilities would be endless. We could create all sorts of new cheese-based products, like sun-cheese pizza or sun-cheese sandwiches. We could even start a new cheese-based economy, where people trade different types of sun-cheese like they would gold or silver.Of course, there would also be some challenges to overcome. For example, how would we prevent the cheese from going bad? Would we need to refrigerate it, or would it stay fresh on its own? And what about the smell? Would the entire planet smell like cheese all the time?Despite these challenges, I believe that a world where the sun is made of cheese would be a wonderful place to live. We would be able to indulge in our love of cheeselike never before, and we would have a new source of foodand energy to sustain us. So let's embrace our wacky ideas and imagine a world where the impossible becomes possible. Who knows? Maybe one day we'll actually get to taste the sun for ourselves.。

Pride and Prejudice
Pride and Prejudice"It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife". This is a sentence from Jane Austen's distinguished novel Pride and Prejudice,which moved me deeply. From the sentence, we can clearly realize the significance of fortune to the marriage at that time. In order to show it to us, the author described the different marriages of Mr. Bennet's five daughters.Actually, Pride and Prejudice mainly focused on Elizabeth's love story with Mr. Darcy. And the author tried to compare Elizabeth's ideal marriage with others so that readers could know about the social reality. As far as I am concerned, the book portrayed not only romantic but also realistic love between males and females. According to people's different ways to deal with their marriage, the book showed us young women's various attitudes toward marriage. As the author considered, it is wrong to marry someone for his fortune、money or position. However, not thinking about the above factors is stupid as well. In a word, Jane Austen objected to marrying for love or treating marriage as a joke. Sheemphasized the importance of ideal marriage and believed that true love is the basis of it.The title of this book has two meanings. "Pride"is used to describe Mr. Darcy, who is a handsome and rich gentleman from the upper-classes in England. "Prejudice" refers to an ordinary lady whose name is Elizabeth. When these two people first met at the ball, Darcy's improper behaviour annoyed Elizabeth. As he had an inborn superiority that he looked down at every person from the lower-classes. Due to her strongself-respect, Elizabeth decided not to pay attention to Mr. Darcy. But soon later, Darcy was attracted by her lovely action and proposed to her regardless of their different status. Elizabeth refused him for his pride. As she thought such pride was the reflection of their different identities and with this it's impossible to own a happy marriage. But gradually, Elizabeth saw Darcy's great changes in some aspect and dispelled misunderstanding and prejudice. At last,Darcy and Elizabeth,the two different even opposite youngsters fell in love .That’s very incredible.From my personal perspective, Elizabeth is anintelligent and obstinate girl. Such characteristics make her have her own principles toward life. Love between Mr. Darcy and Elizabeth is able to enlighten us much. In fact,we are always proud and think something in our mind but not right. We assess others only depend on their background or their color of skin. We hide our true heart .But why don’t we ask ourselves in our heart or mind: what do we feel in fact? What do we need in fact? What do we hate and love in fact? Why not express our real feelings at once? We must learn to stick to our beliefs on the way of pursing love. Do not make any decisions randomly on the basis of status or wealth. Do not change our own ideas easily. Happiness needs to be created by ourselves.。

得到是另一种失去作文好词好句
得到是另一种失去作文好词好句英文回答:Obtaining is but a transient possession, a prelude to the inevitable loss. It is a perpetual cycle, a bittersweet dance of acquisition and relinquishment. The ephemeral nature of all we acquire reminds us of our own mortality, of the fleetingness of time.Like the blooming of a flower, each possession carries within it the seeds of its own decay. The vibrant hues, the delicate petals, all succumb to the relentless march of time. So it is with our material treasures, our relationships, and even our own bodies.The wisdom lies not in clinging desperately to what we have, but in understanding the nature of impermanence. By embracing the transience of all we possess, we open ourselves to the beauty and freedom that lies beyond the fear of loss. We learn to appreciate the present moment, tosavor the sweetness of each experience, knowing that itwill soon pass.In the Buddhist tradition, the concept of "anicca" teaches us that all is impermanent, that all is subject to change. It is not a pessimistic view, but rather arealistic one, a recognition of the fundamental nature of existence. By understanding anicca, we can cultivate a sense of detachment, a freedom from the attachments that bind us to suffering.The Roman poet Horace famously wrote, "Carpe diem," seize the day. It is a reminder to live in the present, to make the most of each moment, for time waits for no one. By embracing the transience of all we have, we can live more fully, more authentically, and with a greater sense of purpose.中文回答:获取乃另一种失去。

problem. We also present a recursively based variety of finite type, which is defined by laws involving only constants (i.e., no variables), with solvable but not uniformly solvable word problem. This second result is the best possible one can provide for varieties defined by laws involving no variables: every finitely based such variety has uniformly solvable word problem. If one were satisfied with varieties with infinitely many operations, then it would be relatively easy to produce an example of a recursively based variety with solvable but not uniformly solvable word problem; we present such an example, essentially due to B. Wells [11], at the end of the paper. Our proof uses the iinsolvability of the halting problem for the universal Turing machine, and the laws defining the variety precisely allow us to model the action of the universal Turing machine in the variety. In the usual proofs that the variety of semigroups has an undecidable word problem, a finitely presented congruence is given such that for any initial Turing machine configuration, the instantaneous descriptions of the Turing machine calculations all lie in the same congruence class. Then laws are added which make the halting state a right and left zero. So, the undecidability of the word problem in this algebra comes from not being able to decide whether a given word (initial configuration) is congruent to the halting state. This algebra contains all possible Turing machine calculations. In our variety each calculation will be modelled by a single algebra. Our approach is based on a different picture of a Turing machine calculation than the sequence of instantaneous descriptions used in semigroups. We view a Turing machine calculation as taking place on a Z x co grid, where the copy of Z with second coordinate n represents the Turing machine tape at time n. To understand the calculation, we must know the alphabet content of each square, which square the head is reading for each time n, and the state the machine is in at time n. There are various possible ways to formalize this insight, so that each Turing machine calculation corresponds to a finitely presented algebra. To ensure that the word problem does not have a uniform solution, we introduce a function which has value 1 when applied to any state the machine reaches and value 0 on the halting state. Then a decision procedure which, given a finite presentation, determines whether 1 is congruent to 0 would solve the halting problem. There are considerable technical difficulties in implementing this idea in such a way that we can prove that each finitely presented algebra in the variety has a decidable word problem. It seems to us that there are two interesting directions that research can follow in the light of the results in this paper. There remains the question of whether a finitely based variety of unary algebras with solvable word problem has uniformly solvable word problem. Another direction research could take is to consider subvarieties of interesting natural varieties. This could either be understood as varieties of X where A' is a favourite class of algebras or, say, congruence modular varieties. This second problem was suggested to us by the persistent question of everyone to whom we told the result, namely 'Is there a natural example?'

ABSTRACT
In the literature two notions of the word problem for a variety occur. A variety has a decidable word problem if every finitely presented algebra in the variety has a decidable word problem. It has a uniformly decidable word problem if there is an algorithm which given a finite presentation produces an algorithm for solving the word problem of the algebra so presented. A variety is given with finitely many axioms having a decidable, but not uniformly decidable, word problem. Other related examples are given as well.
