Polar bears are one of most beautiful animals in this world, but their home, the Arctic, is now in danger. Environmental pollution and global warming are seriously threatening their habitat. Arctic summer sea ice could disappear by 2030, according to climate models. Being already lack of food, they have to be near human settlements where they often acquire a taste for garbage, and that brings bears and humans both into perilous proximity. Based on current projections, scientists say that o-thirds of the world's polar bears could be extinct by mid-century, though a significant cut in greenhouse gas emissions could help halt that decline. So measures should be taken to protect the environment on which they are relying. First, governments should legislate to protect oceans as well as the atmosphere. Second, voices should be made to teach the public of the importance of environment protection. Third, enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems. Of course, every individual should try one's best in daily life by saving water/energy, driving less and so on.译文： 北极熊是在这个世界上最美丽的动物之一，但他们的家，北极，目前正处于危险中。

As regards the study pressure in universities, students vary in their opinions. Some argue too much pressure is harmful to their academic life, while others regard pressure as a driving force that encourages them to work hard and be top students.As far as I am concerned, too much pressure from study will do harm to my academic life. First and foremost, being overburdened by study, students will be exhausted and bee less creative.Moreover, excessive tensions will do no good to their physical health. Only a sound body could guarantee longterm efficient academic study and research.As the proverb goes, “All work and no play makes Jack a dull boy.”It is suggested that university students balance work and leisure by putting aside enough time for relaxation. Only in this way could higher efficiency in academic study be ensured。

考试作文1: Title: A Strange Dream Time Limit: 30 minutes Word Limit: No less than 120 words 参考范文A Strange Dream It was a sweet spring. How pretty it was! I sat on the green meadow and glanced over my book. The warm winds blew gently. I was very tired and lay down to rest for a little while. Very soon I went into a state of dreaming. A little girl sleeps in a corner of the garden. She cries and cries until her sound is broken. Suddenly a bright figure appears before the child. A beautiful fairy stands in front of her. She had a wand in her hand. “Why do you cry? What's the trouble? Perhaps I can help you”, the fairy says. “My mother is dead. I am lonely, and nobody loves me”, answers the girl. “I am a fairy, my home is in the moon. Do you see the light of the moon? How pleasant it is. Would you like to live with me in the moon?” “Thank you, dear fairy, I want to go with you”. The fairy leads the girl into a wood where there are many dwarfs. They look very busy. Every one of them has to dig the soil. They are trying to find varieties of seeds. They cultivate the fields with their hands. All day long though they are exhausted, yet they are forced to work on. Otherwise they will be whipped to death. I made up my mind to save all of those dwarfs. The sound of the bell suddenly came to my ears. I had to wake up. Oh! This is no other than a dream. I will not let it trouble my mind.

I went to visit my uncle on the following afternoon of my arrival, acpanied by my brother. The weather was bitterly cold. Drifts of snow were frozen up by the strong north wind. We wore fur gowns and walked closely together, but still shivered from time to time. My uncle's house was at the other side of the hill, near the city wall. It is a shorter way to go across the h1ll and down straight to his door. We went by that way to his house. When we got on the top of the hill, his house was already within our sight. Then we quickened our paces, excited with a sort of passion which was very dear to us from years pas? We fot the cold already. My uncle was still the same as I remember him. His laugh, his voice and his gesture, were all as familiar to me as if we had not parted even one day. He was still very healthy. He treated us very kind. He asked to prepare tiff for us in spite of our protest. We said that we could eat only a little, since we had already taken much food, but his warm entreaties made us empty all the dishes. I spent the whole afternoon with our cousins in the country. I was very happy to enjoy the fine scenery in the country, and to breathe some fresh air. When it was growing dark, we started for home. On the way back, we talked about the pleasure of the country people and the pain of the farmers.

The vast majority of television advertisements today consist of brief advertising spots, ranging in length from a few seconds to several minutes (as well as program-length infomercials). Advertisements of this sort have been used to sell every product imaginable over the years, from household products to goods and services, to political campaigns. The effect of television advertisements upon the viewing public has been so successful and so pervasive that it is considered impossible for a politician to wage a successful election campaign, in the United States, without use of television advertising

Microeconomics is a branch of economics that studies how individuals, households and firms make decisions to allocate limited resources,[1] typically in markets where goods or services are being bought and sold. Microeconomics examines how these decisions and behaviours affect the supply and demand for goods and services, which determines prices; and how prices, in turn, determine the supply and demand of goods and services.[2][3] Macroeconomics, on the other hand, involves the "sum total of economic activity, dealing with the issues of growth, inflation and unemployment, and with national economic policies relating to these issues"[2] and the effects of government actions (such as changing taxation levels) on them.[4] Particularly in the wake of the Lucas critique, much of modern macroeconomic theory has been built upon 'microfoundations' — i.e. based upon basic assumptions about micro-level behaviour. One of the goals of microeconomics is to analyze market mechanisms that establish relative prices amongst goods and services and allocation of limited resources amongst many alternative uses. Microeconomics analyzes market failure, where markets fail to produce efficient results, as well as describing the theoretical conditions needed for perfect competition. Significant fields of study in microeconomics include general equilibrium, markets under asymmetric information, choice under uncertainty and economic applications of game theory. Also considered is the elasticity of products within the market system. Assumptions and definitions The theory of supply and demand usually assumes that markets are perfectly competitive. This implies that there are many buyers and sellers in the market and none of them have the capacity to significantly influence prices of goods and services. In many real-life transactions, the assumption fails because some individual buyers or sellers or groups of buyers or sellers do have the ability to influence prices. Quite often a sophisticated analysis is required to understand the demand-supply equation of a good. However, the theory works well in simple situations. Mainstream economics does not assume a priori that markets are preferable to other forms of social organization. In fact, much analysis is devoted to cases where so-called market failures lead to resource allocation that is suboptimal by some standard (highways are the classic example, profitable to all for use but not directly profitable for anyone to finance). In such cases, economists may attempt to find policies that will avoid waste directly by government control, indirectly by regulation that induces market participants to act in a manner consistent with optimal welfare, or by creating "missing markets" to enable efficient trading where none had previously existed. This is studied in the field of collective action. It also must be noted that "optimal welfare" usually takes on a Paretian norm, which in its mathematical application of Kaldor-Hicks Method, does not stay consistent with the Utilitarian norm within the normative side of economics which studies collective action, namely public choice. Market failure in positive economics (microeconomics) is limited in implications without mixing the belief of the economist and his or her theory. The demand for various commodities by individuals is generally thought of as the outcome of a utility-maximizing process. The interpretation of this relationship between price and quantity demanded of a given good is that, given all the other goods and constraints, this set of choices is that one which makes the consumer happiest. [edit] Modes of operation It is assumed that all firms are following rational decision-making, and will produce at the profit-maximizing output. Given this assumption, there are four categories in which a firm's profit may be considered. A firm is said to be making an economic profit when its average total cost is less than the price of each additional product at the profit-maximizing output. The economic profit is equal to the quantity output multiplied by the difference between the average total cost and the price. A firm is said to be making a normal profit when its economic profit equals zero. This occurs where average total cost equals price at the profit-maximizing output. If the price is between average total cost and average variable cost at the profit-maximizing output, then the firm is said to be in a loss-minimizing condition. The firm should still continue to produce, however, since its loss would be larger if it were to stop producing. By continuing production, the firm can offset its variable cost and at least part of its fixed cost, but by stopping completely it would lose the entirety of its fixed cost. If the price is below average variable cost at the profit-maximizing output, the firm should go into shutdown. Losses are minimized by not producing at all, since any production would not generate returns significant enough to offset any fixed cost and part of the variable cost. By not producing, the firm loses only its fixed cost. By losing this fixed cost the company faces a challenge. It must either exit the market or remain in the market and risk a complete loss. [edit] Market failure Main article: Market failure In microeconomics, the term "market failure" does not mean that a given market has ceased functioning. Instead, a market failure is a situation in which a given market does not efficiently organize production or allocate goods and services to consumers. Economists normally apply the term to situations where the inefficiency is particularly dramatic, or when it is suggested that non-market institutions would provide a more desirable result. On the other hand, in a political context, stakeholders may use the term market failure to refer to situations where market forces do not serve the public interest. The four main types or causes of market failure are: Monopolies or other cases of abuse of market power where a "single buyer or seller can exert significant influence over prices or output". Abuse of market power can be reduced by using antitrust regulations.[5] Externalities, which occur in cases where the "market does not take into account the impact of an economic activity on outsiders." There are positive externalities and negative externalities.[5] Positive externalities occur in cases such as when a television program on family health improves the public's health. Negative externalities occur in cases such as when a company’s processes pollutes air or waterways. Negative externalities can be reduced by using government regulations, taxes, or subsidies, or by using property rights to force companies and individuals to take the impacts of their economic activity into account. Public goods are goods that have the characteristics that they are non-excludable and non-rivalous and include national defense[5] and public health initiatives such as draining mosquito-breeding marshes. For example, if draining mosquito-breeding marshes was left to the private market, far fewer marshes would probably be drained. To provide a good supply of public goods, nations typically use taxes that compel all residents to pay for these public goods (due to scarce knowledge of the positive externalities to third parties/social welfare); and Cases where there is asymmetric information or uncertainty (information inefficiency).[5] Information asymmetry occurs when one party to a transaction has more or better information than the other party. For example, used-car salespeople may know whether a used car has been used as a delivery vehicle or taxi, information that may not be available to buyers. Typically it is the seller that knows more about the product than the buyer, but this is not always the case. An example of a situation where the buyer may have better information than the seller would be an estate sale of a house, as required by a last will and testament. A real estate broker purchasing this house may have more information about the house than the family members of the deceased. This situation was first described by Kenneth J. Arrow in a seminal article on health care in 1963 entitled "Uncertainty and the Welfare Economics of Medical Care," in the American Economic Review. George Akerlof later used the term asymmetric information in his 1970 work The Market for Lemons. Akerlof noticed that, in such a market, the average value of the commodity tends to go down, even for those of perfectly good quality, because the buyer has no way of knowing whether the product they are buying will turn out to be a "lemon" (a defective product). [edit] Opportunity cost Main article: Opportunity cost Although opportunity cost can be hard to quantify, the effect of opportunity cost is universal and very real on the individual level. In fact, this principle applies to all decisions, not just economic ones. Since the work of the Austrian economist Friedrich von Wieser, opportunity cost has been seen as the foundation of the marginal theory of value. Opportunity cost is one way to measure the cost of something. Rather than merely identifying and adding the costs of a project, one may also identify the next best alternative way to spend the same amount of money. The forgone profit of this next best alternative is the opportunity cost of the original choice. A common example is a farmer that chooses to farm his land rather than rent it to neighbors, wherein the opportunity cost is the forgone profit from renting. In this case, the farmer may expect to generate more profit himself. Similarly, the opportunity cost of attending university is the lost wages a student could have earned in the workforce, rather than the cost of tuition, books, and other requisite items (whose sum makes up the total cost of attendance). The opportunity cost of a vacation in the Bahamas might be the down payment money for a house. Note that opportunity cost is not the sum of the available alternatives, but rather the benefit of the single, best alternative. Possible opportunity costs of the city's decision to build the hospital on its vacant land are the loss of the land for a sporting center, or the inability to use the land for a parking lot, or the money that could have been made from selling the land, or the loss of any of the various other possible uses—but not all of these in aggregate. The true opportunity cost would be the forgone profit of the most lucrative of those listed. One question that arises here is how to assess the benefit of dissimilar alternatives. We must determine a dollar value associated with each alternative to facilitate comparison and assess opportunity cost, which may be more or less difficult depending on the things we are trying to compare. For example, many decisions involve environmental impacts whose dollar value is difficult to assess because of scientific uncertainty. Valuing a human life or the economic impact of an Arctic oil spill involves making subjective choices with ethical implications.
