| 第6、7、8、9、10题：Icebergs are among nature's most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being-somewhere-in faraway, line frigid waters, amid thunderous noise and splashing turbulence, which in most cases no one hears or sees. They exist only a short time and then slowly away just as unnoticed. Objects of sheerest beauty, they have been called. Appearing in an endless variety of shapes, they may be dazzlingly white, or they may be glassy blue, green, or purple, tinted faintly or in darker hues. They are graceful, stately, inspiring-in calm, sunlit seas. But they are also called frightening and dangerous, and that they are in the night, in the fog, and in storms. Even in clear weather one is wise to stay at a safe distance away from them. Most of their bilk is hidden below the visible top. Also, they may roll over unexpectedly, churning the waters around them. Icebergs are parts of glaciers that break off, drift into the water, float about a while, and finally melt. Iceberg afloat today are made of anowflakes that have fallen over long ages of time. They embody snows that drifted down hundreds, or many thousands, or in some cases maybe a million year ago. The snows fell in polar regions and on cold mountains, where they melted only a little or not at all, and so collected to great depths over the years and centuries. As each year's snow accumulation lay on the surface, evaporation and melting caused the snowflakes slowly fell on the top of the old, it too turned to icy grains. So blankets of snow and ice grains mounted layer upon layer and were of such great thickness that the weight of the upper layers compressed the lower ones. With time and pressure from above, the many small ice grains joined and changed to larger crystals, and eventually the deeper crystals merged into a solid mass of ice. 46.

| 第13、14、15、16、17题：There are various ways in which individual economic units can interact with one another.Three basic ways may be described as the market system,the administered system and the traditional system. In a market system individual economic units are free to interact among each other in the market place.It is possible to buy commodities from other economic units or sell commodities to them.In a market,transactions may take place via barter or money exchange.In a barter economy,real goods such as automobiles,shoes,and pizzas are traded against each other.Obviously,finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task.Hence,the introduction of money as a medium of exchange eases transactions considerably.In the modern market economy,goods and services are bought or sold for money. An alternative to the market system is administrative control by some agency over all transactions.This agency will issue edicts or commands as to how much of each goods and service should be produced,exchanged,and consumed by each economic unit.Central planning may be one way of administering such an economy.The central plan,drawn up by the government,shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production,consumption,and exchange for the whole economy. In a traditional society,production and consumption patterns are governed by tradition:parentage,religion,and custom fix every person's place within the economic system.Transactions take place on the basis of tradition,too.People belonging to a certain group or caste may have an obligation to care for other persons,provide them with food and shelter,care for their health, and provide for their education.Clearly,in a system where every decision is made on the basis of tradition alone,progress may be difficult to achieve.A stagnant society may result. 26. What is the main purpose of the passage? A.To outline contrasting types of economic systems. B.To explain the science of economics. C.To argue for the superiority of one economic system. D.To compare barter and moneyexchange markets. 27. In the second paragraph,the word “real” in “real goods” could best be replaced by which of the following? A.high quality. B.concrete. C.utter. D.authentic. 28. According to the passage,a barter economy can lead to ____. A.rapid speed of transactions B.misunderstandings C.inflation D.difficulties for the traders 29. According to the passage,who has the greatest degree of control in an administered system? A.Individual B.Small businesses C.Major corporations D.The government 30. Which of the following is NOT mentioned by the author as a criterion for determining a person's place in a traditional society? A.Family background. B.Age. C.Religious belief. D.Custom. |
