Part I Reading ComprehensionDirections:There are twelve passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.Passage OneIf you have a credit card, you can buy a car, eat a dinner, take a trip, and even get a haircut by charging the cost to your account. In this way you can pay for purchases a month or two later, without any extra charge. Or you may choose to spread out your payments over several months and pay only part of the total amount each month. If you do this, the credit card company or the bank who sponsors the credit card will add a small service charge to your total bill. This is very convenient for the customer. With the credit card in your wallet or purse, you don’t have to carry much cash. This saves your trips to the bank to cash checks or withdraw cash. Also, if you carry credit cards instead of a lot of cash, you don’t have to be concerned about losing your money through carelessness or theft. The card user only has to worry about paying the final bill. This of course can be a problem if you charge more than you can pay for.Credit cards are a big business. Americans spend $16 billion a year on cards and there are already 590 million of them in circulation. Many banks sponsor their own credit companies and issue cards free to their customers. Other credit companies charge their members annual dues. The stores that accept credit cards must pay a small fee to the credit card company — a percentage of purchase price of the merchandise or service. In return, the credit card company promptly pays the store for the merchandise or service. Credit card companies make a profit from the fees they charge the store and also from the fees collected from customers who pay for their charges in monthly installments.However, credit card companies sometimes have problems collecting overdue payments from unreliable customers. Also, the use of stolen, lost, or counterfeit credit cards by criminals has become a big headache for the credit card company that is responsible for the goods and services illegally charged to its customers’ account.Yet, in many ways, the big loser in the credit card system is not the credit card company, the store, or the card user, but rather the general customer. The store makes up for the fees it pays to the credit card company by increasing prices for goods and services. Stores may have more sales if they accept cards, but the added cost to the store when credit cards are accepted instead of cash, is actually passed on to all customers in higher prices. In this way the cash customer suffers for the convenience the credit card customer enjoys.Many feel that it will only be a matter of time before credit cards completely replace cash and checks for both individuals and businesses. In such a credit card economy there would be only one ―super-credit-card-bank-company‖ and each individual would be given his or her card. Each person’s Social Security number would be used as the card number. Firms would use their Federal Identification number. Thus, every individual would be able to pay for everything by credit card —newspapers, cab fares, donations, tools, theater admissions, tuition, children’s allowances, everything. All salary payments would be credited to each individual’s account with the ―super-credit-card-bank-company‖ which would pay one’s bills, deduct state and federal taxes, and deposit what’s left —if anything —into a savings account. Just think of the convenience of getting rid of cash and checks and even eliminating loose change. No need, then, to worry as before, when you wanted to buy a newspaper and you only had a $20 bill.However, with a complete credit card economy, there would still be the problem of thefts of cards, forging of card and lost cards, so the credit card is really not that practical. Something else is needed that is small, always with us, cannot be forged, and easily identifies our account. The answer is your thumbprint; everyone’s thumbprint would be recorded with his or her Social Security number.1. The first paragraph mainly tells us ______.A. how the credit card company worksB. how the credit card company pays the bankC. the advantages of the credit cardD. the disadvantages of the credit card2. According to Paragraph 1, if you have a credit card, you will have to pay a small service charge to ______.A. the credit card companyB. the store where you purchase goodsC. the bank where you deposit moneyD. other customers3. From Paragraph 3 we know that the big loser in the credit card system is ______.A. the general customerB. the storeC. the card userD. the credit card company4. The author thinks that credit cards ______.A. will completely disappear in the futureB. will completely replace cash and checks for both individuals and businesses quicklyC. will completely replace cash and checks for both individuals and businesses sooner or laterD. will not replace cash and checks because there is a matter of time5. From the author’s point of view, the credit card is ______.A. perfect and practicalB. not easily forgedC. still faced with some problems and not so practicalD. more practical than one’s thumbprintPassage TwoSome people argue that the pressure on international sportsmen and sports women kill the essence of sports -- the pursuit of personal excellence. Children kick a football around for fun. When they get older and play for local school teams, they become competitive but they still enjoy playing. The individual representing his country cannot afford to think about enjoying himself; he has to think only about winning. He is responsible for an entire nation's hopes, dream and reputation. A good example is the football World Cup. Football is the world's most important sport. It is even more important now that the United States is seriously taking it up. Winning the World Cup is perhaps the summit of international sporting success. Mention "Argentina‖ to someone and the chances are that he'll think of football. In a sense, winning the World Cup "put Argentina on the map".Sports fans and supporters get quite irrational about the World Cup. People in England felt that their country was somehow important after they won in 1966. Last year thousands of Scots sold their cars, and even their houses, and spent all their money traveling to Argentina, where the finals were played.So, am I arguing that international competition kills the idea of sport? Certainly not! Do the Argentinians really believe that because eleven of their men proved the most skillful at football, their nation is in every sense better than all others? Not really. But it's nice to know that you won, and that in one way at least your country is best.1. What’s the author’s main purpose in the passage ?A) To prove that football is the world's most important sport.B) To show that Argentina is better than all others.C) To compare Scotland with Argentina.D) To explain the role of sport.2. In the second paragraph, the word ―summit‖ means ______.A) highest point B) mountain topC) award D) summary3. According to the passage, Argentina is world-famous because of its ______.A) large number of sports fans and supportersB) success in the football World CupC) obvious position on the mapD) excellence at all important sports4. According to the passage, if a sportsman only thinks about winning, he will ______.A) fail to succeed B) be successfulC) lose enjoyment D) be irrational5. What is the author's attitude towards international games?A) Nations that meet on a football field are unlikely to meet on a battlefield.B) Nations that won football World Cup are regarded best in all aspects.C) Nations that win in international games prove best on the sports field at least.D) Nations that give much attention to international competitions are world-famous in many ways.Passage ThreeAs evidence that the earth’s atmosphere is warming continues to accumulate, scientists are making slow progress toward an answer to the big question raised by the evidence: How much of the warming is due to human activity and how much to natural causes?The UN Intergovernmental Panel on Climate Change, the group of scientists widely considered the most authoritative voice on the subject, has already concluded that there is a ―discernible human influence‖ on the global climate. Now the panel is deep into another of its periodic full-scale scientific assessments of global climate change.Some experts on the problem say the human imprint on climate is becoming clearer, and may even have been the dominant factor in the global warming of recent decades. Not everyone agrees and virtually all experts say that in any case, a reliable estimate of the human imprint’s magnitude still remains some distance off.A number of influences, both natural and man-made, cause the planet’s temperature to vary. The natural ones include changes in solar radiation, and sulfate droplets called aerosols cast aloft by erupting volcanoes, which cool the atmosphere by reflecting sunlight.The human influence stems mostly from emissions of waste industrial gases like carbon dioxide, which trap heat in the atmosphere, and sulfate aerosols from industrial smokestacks.Human factors appeared to be playing a part, but no judgment has been made on whether that part was big, small or in between.One recent piece of evidence suggesting a strong human influence, which seems like to carry some weight with the intergovernmental panel, appeared recently in the journal Nature. Scientists analyzed the global climate record of the last century in an effort to isolate and quantify the major factors producing the century’s rise of about 1 degree Fahrenheit in t he Earth’s average surface temperature.The research team found that in the earlier part of the century, the rise could be explained either by an increase in solar radiation or a combination of stronger solar radiation and heat-trapping greenhouse gases emitted by industrial economies. But they found that after the mid-1970s, when abo ut half the century’s warming took place, that warming resulted largely from the greenhouse gases. Other researchers have lately come to a similar conclusion.―The study represents another jigsaw puzzle piece,‖ said one expert. ―There is still a long way to go in completing the puzzle,‖ he said, ―but we are beginning to see the smile on the face of the Mona Lisa, I think—or perhaps it should be a frown.‖Meanwhile, though, evidence of warming and its effects continues to mount. Earlier this year, scientists at the University of Massachusetts and the University of Arizona reconstructed the average annual surface temperature trend of the Northern Hemisphere for the last 1000 years. While cautioning that margin of error was large enough for render data from the early centuries untrustworthy, they found that 20th century was the warmest of the millennium.This and other analyses have found that the warmest years of all occurred in the 1990s, with 1998 the warmest on record. El Nino, the great pool of warm water in the tropical Pacific Ocean that from time to time heats the atmosphere and disrupts weather patterns, was responsible for some of the 1998 heating. An analysis, however, has shown that when El Nino’s effects are filtered out of the global temperature record statistically, 1998 still ranks as the warmest year.Two studies reported in Nature last month suggest that the warming is being reflected in patterns of wildlife behavior and distribution. In one study, 13 scientists analyzed distribution patterns of 35 species, their range of habitat had shifted northward by 35 to 240 kilometers coincidentally with Europe’s warming trend.In the other study, some British scientists analyzed the nesting habits of 20 species of birds in Britain. They found that, again coincident with a recent warming trend, the birds were laying their eggs earlier in the spring. This is the latest in a series of studies indicating that meteorological spring is coming earlier in the Northern Hemisphere[5]. Some have also shownthat fall is coming later.A third study in Nature reported, on the basis of bubbles of atmospheric gas contained in ice cores extracted from the Antarctic ice sheet, that present-day atmospheric levels of heating-trapping carbon dioxide were higher than at any other time in the last 420000 years. At 360 parts per million, they are 20 percent higher than in any previous warm period between ice ages and double the typical concentrations during an ice age.1. The earth’s atmosphere is warming, ______.A. mainly because of human factorB. mainly because of natural causesC. the reason of which is completely unknownD. which is being studied by scientists2. Maybe sulfate aerosols are all caused by ______.A. erupting volcanoesB. industrial smokestacksC. both A and BD. none of the above3. Which of the following is TRUE?A. About half of the 20th century’s rise in average global climate resulted mostly from the greenhouse gases.B. Half of the 20th century warming took place in the last thirty years.C. The 20th century is the warmest in the last one thousand years.D. All of the above.4. The global climate rise in the earlier part of the 20th century is due to ______.A. an increase in solar radiation onlyB. greenhouse gasesC. eruption of volcanoesD. either an increase in solar radiation or a combination of stronger solar radiation and greenhouse effect5. According to the study of bubbles of atmospheric gas contained in ice cores extracted from the Antarctic ice sheet, we can infer that ______.A. present-day climate is the warmest in historyB. present-day climate is 20 percent hotter than that of the last 420 000 yearsC. present-day climate is twice hotter than that of an ice ageD. in 1998 the carbon dioxide concentration in the atmosphere are the highest on recordPassage FourThe current energy security system was created in response to the 1973 Arab oil embargo to ensure coordination among the industrialized countries in the event of a disruption in supply, encourage collaboration on energy policies, and deter any future use of an ―oil weapon‖ by exporters. Its key elements are the Paris-based International Energy Agency (IEA), whose members are the industrialized countries; strategic stockpiles of oil, including the U.S. Strategic Petroleum Reserves; continued monitoring and analysis of energy markets and policies; and energy conservation and coordinated emergency sharing of supplies in the event of a disruption. The emergency system was set up to offset major disruptions that threatened the global economy and stability, not to manage prices and the commodity cycle. Since the system’s inception in the 1970s, a coordinated emergency drawdown of strategic stockpiles has occurred only twice: on the eve of the Gulf War in 1991 and in the autumn of 2005 after Hurricane Katrina.Experience has shown that to maintain energy security countries must abide by several principles. The first and most familiar is what Churchill urged more than 90 years ago: diversification of supply. Multiplying one’s supply sources reduces the impact of a disruption in supply from one source by providing alternatives, serving the interests of both consumers and producers, for whom stable markets are a prime concern. But diversification is not enough. A second principle is resilience, a ―security margin‖ in the energy supply system that provides a buffer against shocks and facilitates recovery after disruptions. Resilience can come from many factors, including sufficient spare production capacity, strategic reserves, backup supplies ofequipment, adequate storage capacity along the supply chain, and the stockpiling of critical parts for electric power production and distribution, as well as carefully conceived plans for responding to disruptions that may affect large regions. Hence the third principle: recognizing the reality of integration. There is only one oil market, a complex and worldwide system that moves and consumes about 86 million barrels of oil every day. For all consumers, security resides in the stability of this market. Secession is not an option.A fourth principle is the importance of information. High-quality information underpins well-functioning markets. On an international level, the IEA has led the way in improving the flow of information about world markets and energy prospects. That work is being complemented by the new International Energy Forum, which will seek to integrate information from producers and consumers. Information is no less crucial in a crisis, when consumer panics can be instigated by a mixture of actual disruptions, rumors, and fear. In such situations, governments and the private sector should collaborate to counter panics with high-quality, timely information.As important as these principles are, the past several years have highlighted the need to expand the concept of energy security in two critical dimensions: the recognition of globalization of the energy security system, which can be achieved especially by engaging China and India, and the acknowledgement of the fact that the entire energy supply chain needs to be protected.1. The energy security system was established for the following long-term purpose EXCEPT ______.A. protecting profits of industrialized countries during Arab oil embargoB. making effective coordination among those industrialized countriesC. promoting cooperation in making policies about energyD. preventing oil exporters from using oil as a weapon against other countries2. Which of the following statements about International Energy Agency is NOT true?A. Its headquarter is located in Paris.B. Its members include developed and developing countries.C. It monitors and analyzes the energy market and policies.D. It makes great efforts to save energy and deal with oil disruption.3. The first and foremost thing that both consumers and producers are concerned about is ______.A. various supply sourcesB. stable energy marketsC. the largest profitsD. reasonable prices4. Integration, the third principle to maintain energy security, means to ______.A. recognize the reality of energy shortageB. guarantee the stability of energy marketC. realize the unity of the worldwide marketD. protect one’s independent interests5. The main purpose of this passage is to ______.A. convince readers that energy security is importantB. introduce the major energy organizations of U.S.C. inform readers what the energy security system is likeD. present principles for ensuring energy securityPassage FiveNormally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, thoughthis is not in fact done as a regular practice.For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.The Internet seems to have just arrived, so how can we possibly imagine what will replace it? In truth, early versions of the Net have been around since the 1960s and 70s, but only after the mid-1990s did it begin to have a serious public impact. Since 1994, the population of users has grown from about 13 million to more than 300 million around the world.What will the Internet be like 20 years from now?Like the rest of infrastructure, the Internet will eventually seem to disappear by becoming widespread. Most access will probably be via high-speed, low-power radio links. Most handheld, fixed and mobile appliances will be Internet enabled. This trend is already discernible in the form of Internet-enabled cell phones and personal digital assistants. Like the servants of centuries past, our household helpers will chatter with one another and with the outside help.So many appliances, vehicles and buildings will be online by 2020 that it seems likely there will be more things on the Internet than people. Internet-enabled cars and airplanes are coming online, and smart houses are being built every day. Eventually, programmable devices will become so cheap that we will embed them in the cardboard boxes into which we put other things for storage or shipping. These passive ―computers‖ will be activated as they pass sensors and will be able to bo th emit and absorb information. Such innovations will facilitate increasingly automatic manufacturing, inventory control, shipping and distribution. Checkout at the grocery store will be fully automatic, as will payment via your digital wallet.The advent of programmable, mini-scale machines will extend the Internet to things with the size of molecules that can be injected under the skin, leading to Internet-enabled people. Such devices, together with Internet-enabled sensors embedded in clothing, will avoid a hospital stay for medical patients who would otherwise be there only for observation. The speech processor used today in cochlear implants for the hearing impaired could easily be connected to the Internet; listening to Internet radio could soon be a direct computer-to-brain experience!The Internet will undergo substantial alteration as optical technologies allow the transmission of many trillions of bits per second on each Internet’s fiber-optic backbone network. The core of the network will remain optical, and the edges will use a mix of access technologies, ranging from radio and infrared to optical fiber and the old twisted-pair copper telephone lines.By then, the Internet will have been extended, by means of an interplanetary Internet backbone, to operate in outer space.How will this pervasive Internet access affect our daily lives? More and more of the world’s inform ation will be accessible instantly and from virtually anywhere. In an emergency, our health records will be available for remote medical consultation with specialists and perhaps even remote surgery. More and more devices will have access to the global positioning system, increasing the value of geographically indexed databases. Using GPS with speech-understanding software that is emerging today, we will be able to get directions from our Internet as easily as we once got them at a filling station.Is there any downside to a society suffused with information and the tools to process it?Privacy will come at a premium. Enormous quantities of data about our daily affairs will flow across the Internet, working to make our lives easier. Despite our preference for giving up privacy in exchange for convenience, our experiences online may make us yearn for the anonymity of the past. Who should have access to our medical records and our financial information, and how will that access be controlled? Will we be able to search and use the vast information stored online without leaving trails across the Net? How will business transactions be taxed, and in what jurisdictions will disputed electronic transactions be resolved? How will intellectual property be protected? How will we prove that contracts were signed on a certain date, or that their terms and conditions have not been electronically altered? There are technical answers for many of these questions, but some will require international agreements before they can be resolved.Perhaps even more daunting, in the face of Internet-wide virus attacks, is the realization that we will depend in larger and larger measure on the network’s functioning reliably. Making this system of millions of networks robust is a challe nge for the present generation of Internet engineers. But I am an optimist and believe we are going to live in a world abundantwith information and with the tools needed to use it wisely.1. The main idea the author tries to convey is that ______.A. the Internet has already arrivedB. the Internet began to have a serious impact in 1990sC. the Internet is getting more and more popularD. the Internet is developing fast ever since its appearance2. The Internet might seem to disappear because most access to the Internet is probably realized by ______.A. high-speed, low-power radio linksB. handheld mobile appliancesC. internet-enabled cell phonesD. personal digital assistants3. The Internet will have a significant change thanks to optical technology, which ______.A. will make the Internet access more flexibleB. will make the Internet transmission more rapidlyC. will make the Internet communication more convenientD. will make the Internet more useful in our life4. The primary concern of online experience is ______.A. privacyB. convenienceC. pricingD. conflict5. The author’s attitude toward the future of the Internet is ______.A. doubtfulB. cheerfulC. biasedD. depressedPassage SixI spent some of the most exciting days of my life wor king on the eastern shores of Kenya’s Lake Turkana, searching for the fossilized remains of our early ancestors. We did not always find what we wanted, but every day there was much more to discover than the traces of our own predecessors. The fossils, some quite complete, others mere fragments, spoke of another world in which the ancestors of many of today’s African mammals roamed in the rich grassland and forest fringes between 1.5 million and 2 million years ago. The environment was not too different from the wetter grasslands of Africa today, but it was full of amazing animals that are now long extinct.One in particular I would have loved to see alive was a short-necked giraffe relative that had huge ―antlers‖, some with a span across the horns of close to almost 3 meters. There were buffalo-size antelopes with massive curving horns, carnivores that must have looked like saber-toothed lions, two distinct species of hippo and at least two types of elephants. We may never know the full extent of this incredible mammalian diversity, but there were probably more than twice as many species a million years ago as there are today.That was true not just for Africa. The fossil record tells the same story everywhere. Most of life’s experiments have ended in extinction. It is estimated that more than 95% of the species that have existed over the past 600 million years are gone.So, should we be concerned about the current spasm of extinction, which has been accelerated by the inexorable expansion of agriculture and industry? Is it necessary to try to slow down a process that has been going on forever?I believe it is. We know that the well-being of human race is tied to the well-being of many other species, and we can’t be sure which species are most important to our own survival.But dealing with the extinction crisis is no simple matter, since much of the world’s biodiversity resides in its poorest nations, especially in Asia, Africa and Latin America. Can such countries justify setting aside national parks and nature reserves where human encroachment and even access is forbidden? Is it legitimate to spend large sums of money to save。

Part I Reading ComprehensionPassage 1Geology is a natural science. With it men can discover all kinds of useful minerals. Geology studies the earth. But of the three spheres, the atmosphere, the hydrosphere and the lithosphere, it only directly studies the lithosphere. It studies the composition and distribution of material in the earth’s crust. It studies also the formation, changes and development of rocks and minerals in the earth’s crust.Geology is a very complex science. There are many branches in geology. Mineralogy is the science of the minerals. Petrology is the science of the rocks. Geomorphology deals with origin of landscapes and changes in them. Historical geology traces the evolution and development of the earth and of the animals and plants on it. Stratigraphy studies the sequence of the rocks in the earth’s crust. Paleontology deals with the ancient animals and plants. These are just a few of the most important branches of geology.Geology is a very important science. We depend upon geology for the discovery of mineral deposits needed by the various industries. A lot of minerals are used as fuel and raw materials. Without them industrialization is impossible. Minerals are also used as fertilizers in agriculture. China is very rich in mineral deposits of all kinds. The study of geology will help us to discover them.Petroleum occurs widely in the earth as gas, liquid, semisolid, or solid, or in more than one of these states at a single place. Chemically any petroleum is an extremely complex mixture of hydrocarbon (hydrogen and carbon) compounds, with minor amounts of nitrogen, oxygen, and sulfur as impurities. Liquid petroleum, which is called crude oil to distinguish it from refined oil, is the most important commercially. It consists chiefly of the liquid hydrocarbons, with varying amounts of dissolved gases, bitumens, and impurities.Petroleum gas, commonly called natural gas to distinguish it from manufactured gas,consists of the lighter paraffin hydrocarbons, of which the most abundant is methane gas (CH4). The semisolid and solid forms of petroleum consist of the heavy hydrocarbons and bitumens.Geology plays an important role in the search for oil and natural gas. Four prerequisites are necessary for oil (and gas) to accumulate in commercial quantities in an area: (1) The oil originates in a source bed, and a marine shale, once a black mud rich in organic compounds, is thought to be a common source rock. (2) The oil then migrates to a permeable reservoir rock, and to do this it may travel for long distances both vertically and horizontally. Oil cannot move through the tiny openings of the shale source beds rapidly enough to be extracted profitably. (3) A nonpermeable layer must occur above a reservoir bed. Since oil is lighter than water, it tends to move upward through openings and cracks until it encounters impervious beds that it cannot penetrate. The oil may then accumulate beneath the impervious layers. Some gas occurs in solution within the oil, and if enough is present it separates out to occupy the uppermost region of such a trap. (4) A favorable structure must exist to concentrate the oil and anticlines, salt plugs, and faults are common examples. A fault zone may itself be impervious, or faulting may have shifted an impervious bed so that it now blocks a reservoir bed. Stratigraphic traps tend to be more difficult to locate and may form where tilted reservoir beds are overlain unconformably by impervious layers or where the reservoir beds become thinner up-dip and wedge out within enclosing impervious beds. Thus oil that was once distributed in sparse amounts throughout a very large volume of rock may now be richly concentrated within the uppermost portions of favorable reservoir rocks.The task of the geologist is the location of promising structures in regions where rocks are favorable for the occurrence of the other prerequisites. Drilling a hole is then the only known method of determining whether or not oil is present in the structure.1. What is mainly dealt with in the passage?A. The formation of oil.B. The formation of rocks.C. The general introduction of geology.D. The roles of geology in finding oil.2. Geology is a natural science and it does NOT study______.A. the minerals in the earth’s crustB. the rocks in the earth’s crustC. the evolution and development of the earthD. the origin of the atmosphere surrounding the earth3. One prerequisite for oil to accumulate in quantity is that the oil originates in ______.A. a source rockB. a black mudC. the seawaterD. organic compounds4. In the formation of oil, a nonpermeable layer above a reservoir bed is necessary because it can ______.A. accelerate the travel speed of the oilB. hinder the oil to move upwardC. help the oil to move upwardD. help people to discover the oil5. Which of the following statements is TRUE?A. Drilling a hole is one of the known methods of determining whether or not oil is present inthe structure.B. A geologist usually tries to locate promising structures in regions where rocks are favorablefor the occurrence of the other prerequisites.C. An unfavorable structure must exist to concentrate the oil.D. A permeable layer must occur above a reservoir bed.Passage 2In order to talk about the nature of the universe and to discuss questions such as whether it has a beginning or an end, you have to be clear about what a scientific theory is. I shall take the simple-minded view that a theory is just a model of the universe, or a restricted part of it, and a set of rules that relate quantities in the model to observations that we make.It exists only in our minds and does not have any other reality. A theory is a good theory if it satisfies two requirements. It must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations.For example, Aristotle’s theory that everything was made out of four elements, earth, air, fire, and water, was simple enough to qualify, but it did not make any definite predictions. On the other hand, Newton’s theory of gravity was based on an even simpler model, in which bodie s attracted each other with a force that was proportional to a quantity called their mass and inversely proportional to the square of the distance between them. Yet it predicts the motion of the sun, the moon, and the planets to a high degree of accuracy.Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. On the other hand, you can disprove a theory by finding even a single observation that disagrees with the predictions of the theory. In practice, what often happens is that a new theory that is devised is really an extension of the previous theory.The eventual goal of science is to provide a single theory that describes the whole universe. However, the approach most scientists actually follow is to separate the problem into two parts. First, there are the laws that tell us how the universe changes with time. If we know what the universe is like at any one time, these physical laws tell us how it will look at any later time. Second, there is the question of the initial state of the universe. Some people feel that science should be concerned with only the first part; they regard the question of the initial situation as a matter for religion. They would say that God could have started the universe off any way he wanted. That may be so, but in that case he also could have made it develop in a completely arbitrary way. Yet it appears that he chose to make it evolve in a very regular way according to certain laws. It therefore seems equally reasonable to suppose that there are also laws governing the initial state.It turns out to be very difficult to devise a theory to describe the universe all in one go. Instead, we break the problem up into bits and invent a number of partial theories. Each of these partial theories describes and predicts a certain limited class of observations, neglecting the effects of other quantities, or representing them by simple sets of numbers. It may be that this approach is completely wrong. If everything in the universe depends on everything else in a fundamental way, it might be impossible to get close to a full solution by investigating parts of the problem in isolation. Nevertheless, it is certainly the way that we have made progress in the past. The classical example is the Newtonian theory of gravity, which tells us that the gravitational force between two bodies depends only on one number associated with each body, its mass, but isotherwise independent of what the bodies are made of. Thus one does not need to have a theory of the structure and constitution of the sun and the planets in order to calculate their orbits.Today scientists describe the universe on terms of two basic partial theories —the general theory of relativity and quantum mechanics. They are the great intellectual achievements of the first half of this century. The general theory of relativity describes the force of gravity and the large-scale structure of the universe. Quantum mechanics, on the other hand, deals with phenomena on extremely small scales, such as a millionth of a millionth of an inch. Unfortunately, however, these two theories are known to be inconsistent with each other — they cannot both be correct. One of the major endeavors in physics today, is the search for a new theory that will incorporate them both — a quantum theory of gravity. We do not yet have such a new theory, and we may still be a long way from having one, but we do already know many of the properties that it must have.6. According to the author, a theory is all of the following EXCEPT for ______.A. a model of the universeB. a restricted part of the universeC. a set of rulesD. a reality7. The difference between Aristotle’s theory and Newton’s theory is ______.A. Aristotle’s theory can describe a large class of observations, while Newton’s cannot.B. Newton’s theory can describe a large class of observations, while Aristotle’s cannot.C. Aristotle’s theory can make a definite prediction of the future observations, while Newton’scannot.D. Newton’s theory can make a definite prediction of the future observations, while Aristotle’scannot.8. The approach adopted by most scientists to devise a theory to describe the universe is_________.A. to break the problem up into bits and invent a number of partial theoriesB. to invent one theory to describe the whole universeC. to combine general theory of relativity with quantum mechanicsD. to study the origin of the universe9.It is described in Newton’s theory of gravity that bodies attracted each other with a force which is ______.A. inversely proportional to their massB.inversely proportional to the square of the distance between themC. proportional to the square of the distance between themD. proportional to the constitution of them10.According the passage, the great intellectual achievements of the first half of the 20th century are ______.A. Newton’s theory of gravity and the general theory of relativityB. Newton’s theory of gravity and quantum mechanicsC. the general theory of relativity and quantum mechanicsD. the general theory of relativity and the quantum theory of gravityPassage 3The current energy security system was created in response to the 1973 Arab oil embargo toensure coordination among the industrialized countries in the event of a disruption in supply, encourage collaboration on energy policies, and deter any future use of an “oil weapon”by exporters. Its key elements are the Paris-based International Energy Agency (IEA), whose members are the industrialized countries; strategic stockpiles of oil, including the U.S. Strategic Petroleum Reserves; continued monitoring and analysis of energy markets and policies; and energy conservation and coordinated emergency sharing of supplies in the event of a disruption. The emergency system was set up to offset major disruptions that threatened the global economy and stability, not to manage prices and the commodity cycle. Since the system’s inception in the 1970s, a coordinated emergency drawdown of strategic stockpiles has occurred only twice: on the eve of the Gulf War in 1991 and in the autumn of 2005 after Hurricane Katrina.Experience has shown that to maintain energy security countries must abide by several principles. The first and most familiar is what Churchill urged more than 90 years ago: diversification of supply. Multiplying one’s supply sources reduces the impact of a disruption in supply from one source by providing alternatives, serving the interests of both consumers and producers, for whom stable markets are a prime concern. But diversification is not enough. A second principle is resilience, a “security margin”in the energy supply system that provides a buffer against shocks and facilitates recovery after disruptions. Resilience can come from many factors, including sufficient spare production capacity, strategic reserves, backup supplies of equipment, adequate storage capacity along the supply chain, and the stockpiling of critical parts for electric power production and distribution, as well as carefully conceived plans for responding to disruptions that may affect large regions. Hence the third principle: recognizing the reality of integration. There is only one oil market, a complex and worldwide system that moves and consumes about 86 million barrels of oil every day. For all consumers, security resides in the stability of this market. Secession is not an option.A fourth principle is the importance of information. High-quality information underpins well-functioning markets. On an international level, the IEA has led the way in improving the flow of information about world markets and energy prospects. That work is being complemented by the new International Energy Forum, which will seek to integrate information from producers and consumers. Information is no less crucial in a crisis, when consumer panics can be instigated by a mixture of actual disruptions, rumors, and fear. In such situations, governments and the private sector should collaborate to counter panics with high-quality, timely information.As important as these principles are, the past several years have highlighted the need to expand the concept of energy security in two critical dimensions: the recognition of globalization of the energy security system, which can be achieved especially by engaging China and India, and the acknowledgement of the fact that the entire energy supply chain needs to be protected.11. The energy security system was established for the following long-term purpose EXCEPT ______.A. protecting profits of industrialized countries during Arab oil embargoB. making effective coordination among those industrialized countriesC. promoting cooperation in making policies about energyD. preventing oil exporters from using oil as a weapon against other countries12. Which of the following statements about International Energy Agency is NOT true?A. Its headquarter is located in Paris.B.Its members include developed and developing countries.C. It monitors and analyzes the energy market and policies.D. It makes great efforts to save energy and deal with oil disruption.13. The first and foremost thing that both consumers and producers are concerned about is ______.A. various supply sourcesB. stable energy marketsC. the largest profitsD. reasonable prices14. Integration, the third principle to maintain energy security, means to ______.A. recognize the reality of energy shortageB. guarantee the stability of energy marketC.realize the unity of the worldwide marketD. protect one’s independent interests15. The main purpose of this passage is to ______.A. convince readers that energy security is importantB. introduce the major energy organizations of U.S.C. inform readers what the energy security system is likeD. present principles for ensuring energy securityPassage 4I spent some of the most exciting days of my life working on the eastern shores of Kenya’s Lake Turkana, searching for the fossilized remains of our early ancestors. We did not always find what we wanted, but every day there was much more to discover than the traces of our own predecessors. The fossils, some quite complete, others mere fragments, spoke of another world in which the ancestors of many of today’s African mammals roamed in the rich grassland and forest fringes between 1.5 million and 2 million years ago. The environment was not too different from the wetter grasslands of Africa today, but it was full of amazing animals that are now long extinct.One in particular I would have loved to see alive was a short-necked giraffe relative that had huge “antlers”, some with a span across the horns of close to almost 3 meters. There were buffalo-size antelopes with massive curving horns, carnivores that must have looked like saber-toothed lions, two distinct species of hippo and at least two types of elephants. We may never know the full extent of this incredible mammalian diversity, but there were probably more than twice as many species a million years ago as there are today.That was true not just for Africa. The fossil record tells the same story everywhere. Most of life’s experiments have ended in extinction. It is estimated that more than 95% of the species that have existed over the past 600 million years are gone.So, should we be concerned about the current spasm of extinction, which has been accelerated by the inexorable expansion of agriculture and industry? Is it necessary to try to slow down a process that has been going on forever?I believe it is. We know that the well-being of human race is tied to the well-being of many other species, and we can’t be sure which species are most important to our own survival.But dealing with the extinction crisis is no simple matter, since much of the world’s biodiversity resides in its poorest nations, especially in Asia, Africa and Latin America. Can such countries justify setting aside national parks and nature reserves where human encroachment and even access is forbidden? Is it legitimate to spend large sums of money to save some species —be it an elephant or an orchid —in a nation in which a sizable percentage of the people are living below the poverty line?Such questions make me uneasy about promoting wildlife conservation in impoverished nations. Nonetheless, I believe that we can —and should —do a great deal. It’s a matter of changing priorities. Plenty of money is available for scientific field studies and conferences on endangering species. But what about boots and vehicles for park personnel who protect wildlife from poachers? What about development aid to give local people economic alternatives to cutting forests and plowing over the land? That kind of funding is difficult to come by.People in poor countries should not be asked to choose between their own short-term survival and long-term environmental needs. If their governments are willing to protect the environment, the money needed should come from international sources. To me, the choice is clear. Either the more affluent world helps now or the world as a whole will lose out.Of course, we must be careful not to allow the establishment of slush funds or rely on short-term, haphazard handouts that the world would probably go to waste. We need a permanent global endowment devoted to wildlife protection, funded primarily by the governments of the industrial nations and international aid agencies. The principal could remain invested in the donor nations as the interest flowed steadily into conservation efforts.How to use those funds would be a matter of endless debate. Should local communities be entitled to set the agenda, or should outside experts take control? Should limited hunting be allowed in parks, or should they be put off limits? Mistakes will be made, the landscape will keep changing, and species will still be lost, but the difficulty of the task should not lead us to abandon hope. Many of the planet’s natural habitats are gone forever, bur many others can be sav ed and in time restored.A major challenge for the 21st century is to preserve as much of our natural estate as possible. Let us resist with all our efforts any moves to reduce the amount of wild land available for wild species. And let us call upon the world’s richest nations to provide the money to make that possible. That would not be a contribution to charity; it would be an investment in the future of humanity —and all life on Earth.16. The purpose of the author’s work on the eastern shores of Lake Turkana was ______.A. to discover the fossil history of African mammalsB. to search for the traces of the extinct animal speciesC. to discover the fossils of human being’s predecessorsD. to study the fragments of the fossils of the ancestors of African mammals17.

Is it necessary to provide woodcutters in poverty-stricken nations with the economicalternatives to making a living on cutting down trees?D. Is it necessary to change our priorities and provide more equipment and support for wildlifeprotection personnel?19. The author’s main purpose of writing this article is ______.A. to champion a global fund mainly from the affluent nations and international efforts topreserve the wildlifeB. to warn the rich nations against the losing out in protecting the global environmentC. to persuade the impoverished people to sacrifice their short-term benefit for long-termprotection of the biodiversityD. to take into account the difficulty of wildlife protection and stop endless debate20. The author’s attitude towards preserving the natural habitats is ______.A. uncertainB. positiveC. hopelessD. uneasyPassage 5The Internet seems to have just arrived, so how can we possibly imagine what will replace it? In truth, early versions of the Net have been around since the 1960s and 70s, but only after the mid-1990s did it begin to have a serious public impact. Since 1994, the population of users has grown from about 13 million to more than 300 million around the world.What will the Internet be like 20 years from now?Like the rest of infrastructure, the Internet will eventually seem to disappear by becoming widespread. Most access will probably be via high-speed, low-power radio links. Most handheld, fixed and mobile appliances will be Internet enabled. This trend is already discernible in the form of Internet-enabled cell phones and personal digital assistants. Like the servants of centuries past, our household helpers will chatter with one another and with the outside help.So many appliances, vehicles and buildings will be online by 2020 that it seems likely there will be more things on the Internet than people. Internet-enabled cars and airplanes are coming online, and smart houses are being built every day. Eventually, programmable devices will become so cheap that we will embed them in the cardboard boxes into which we put other things for storage or shipping. These passive “computers” will be activated as they pass sensors and will be able to both emit and absorb information. Such innovations will facilitate increasingly automatic manufacturing, inventory control, shipping and distribution. Checkout at the grocery store will be fully automatic, as will payment via your digital wallet.The advent of programmable, mini-scale machines will extend the Internet to things with the size of molecules that can be injected under the skin, leading to Internet-enabled people. Such devices, together with Internet-enabled sensors embedded in clothing, will avoid a hospital stay for medical patients who would otherwise be there only for observation. The speech processor used today in cochlear implants for the hearing impaired could easily be connected to the Internet; listening to Internet radio could soon be a direct computer-to-brain experience!The Internet will undergo substantial alteration as optical technologies allow the transmission of many trillions of bits per second on each Internet’s fiber-optic backbone network. The core of the network will remain optical, and the edges will use a mix of access technologies, ranging from radio and infrared to optical fiber and the old twisted-pair copper telephone lines.By then, theInternet will have been extended, by means of an interplanetary Internet backbone, to operate in outer space.How will this pervasive Internet access affect our daily lives? More and more of the world’s information will be accessible instantly and from virtually anywhere. In an emergency, our health records will be available for remote medical consultation with specialists and perhaps even remote surgery. More and more devices will have access to the global positioning system, increasing the value of geographically indexed databases. Using GPS with speech-understanding software that is emerging today, we will be able to get directions from our Internet as easily as we once got them at a filling station.Is there any downside to a society suffused with information and the tools to process it?Privacy will come at a premium. Enormous quantities of data about our daily affairs will flow across the Internet, working to make our lives easier. Despite our preference for giving up privacy in exchange for convenience, our experiences online may make us yearn for the anonymity of the past. Who should have access to our medical records and our financial information, and how will that access be controlled? Will we be able to search and use the vast information stored online without leaving trails across the Net? How will business transactions be taxed, and in what jurisdictions will disputed electronic transactions be resolved? How will intellectual property be protected? How will we prove that contracts were signed on a certain date, or that their terms and conditions have not been electronically altered? There are technical answers for many of these questions, but some will require international agreements before they can be resolved.Perhaps even more daunting, in the face of Internet-wide virus attacks, is the realization that we will depend in larger and larger measure on the network’s functioning relia bly. Making this system of millions of networks robust is a challenge for the present generation of Internet engineers. But I am an optimist and believe we are going to live in a world abundant with information and with the tools needed to use it wisely.21. The main idea the author tries to convey is that ______.A. the Internet has already arrivedB. the Internet began to have a serious impact in 1990sC. the Internet is getting more and more popularD. the Internet is developing fast ever since its appearance22. The Internet might seem to disappear because most access to the Internet is probably realized by ______.A. high-speed, low-power radio linksB. handheld mobile appliancesC. internet-enabled cell phonesD. personal digital assistants23. The Internet will have a significant change thanks to optical technology, which ______.A. will make the Internet access more flexibleB. will make the Internet transmission more rapidlyC. will make the Internet communication more convenientD. will make the Internet more useful in our life24.

Now the panel is deep into another of its periodic full-scale scientific assessments of global climate change.Some experts on the problem say the human imprint on climate is becoming clearer, and may even have been the dominant factor in the global warming of recent decades. Not everyone agrees and virtually all experts say that in any case, a reliable estimate of the human imprint’s magnitude still remains some distance off.A number of influences, both natural and man-made, cause the planet’s temperature to vary. The natural ones include changes in solar radiation, and sulfate droplets called aerosols cast aloft by erupting volcanoes, which cools the atmosphere by reflecting sunlight.The human influence stems mostly from emissions of waste industrial gases like carbon dioxide, which trap heat in the atmosphere, and sulfate aerosols from industrial smokestacks.Human factors appeared to be playing a part, but no judgment has been made on whether that part was big, small or in between.One recent piece of evidence suggesting a strong human influence, which seems likely to carry some weight with the intergovernmental panel, appeared recently in the journal Nature. Scientists analyzed the global climate record of the last century in an effort to isolate and quantify the major factors producing the century’s rise of about 1 degree Fahrenheit in the Earth’s average surface temperature.The research team found that in the earlier part of the century, the rise could be explained either by an increase in solar radiation or a combination of stronger solar radiation and heat-trapping greenhouse gases emitted by industrial economies. But they found that after the mid-1970s, when about half the century’s warming took place, the warming resulted largely from the greenhouse gases.Meanwhile, evidence of warming and its effects continues to mount. Earlier this year, scientists at the University of Massachusetts and the University of Arizona reconstructed the average annual surface temperature trend of the Northern Hemisphere for the last 1000 years. They found that the 20th century was the warmest of the millennium and that the warmest years of all occurred in the 1990s, with 1998 the warmest on record.1.The earth’s atmosphere is warming, ______.A.mainly because of human factorB.mainly because of natural causesC.the reason of which is unknownD.which is being studied by scientists2.Maybe sulfate aerosols are all caused by ______.A.erupting volcanoesB.industrial smokestacksC.both A and BD.none of the above3.In the 20th century the global climate has risen by ______.A.20%B.about 1 degree FahrenheitC. 1 degree centigradeD.We have no idea about this.4.Which of the following is TRUE according to the passage?A.About half of the 20th century’s rise in average global climate resulted mostly from the greenhousegases.B.Half of the 20th century’s warming took place in the last thirty years.C.The 20th century is the warmest in the last 1000 years.D.All of the above.5.The global climate rise in the earlier part of the 20th century is due to ______.A.an increase in solar radiation onlyB.greenhouse gasesC.eruption of volcanoesD.either an increase in solar radiation or a combination of stronger solar radiation and greenhouse gases Passage 2The Sino-foreign joint ventures should export their products and earn foreign exchange as much as possible to balance their foreign exchange income and expenditure. With a view to encouraging foreign investors to establish technology-intensive and knowledge-intensive joint ventures in China and bring in advanced technological processes, technology, equipment, materials and scientific management skills that suit China, some joint ventures may sell a part or most part of their products in China with the approval of relevant Chinese departments. The products are: (1) products which are produced with advanced equipment, technology and technological processes and are short in supply in China; (2) Products that can replace China’s traditional imports;(3) products that are better than their Chinese counterparts in terms of quality, property, varieties and specifications.The following measures are taken to balance the foreign exchange income and expenditure of joint ventures.With the approval of the State Foreign Exchange Control Administration, joint ventures are allowed to receive a certain amount of foreign exchange when selling their products in China.After being approved, foreign investors are allowed to buy goods in China with their profits in Renminbi (RMB) for export. But the export of those goods managed by the state through export quota and export license must be approved by the Ministry of Foreign Economic Relations and Trade.Foreign investors are allowed, in accordance with the relevant regulations of “The Law of the People’s Republic of China on Joint Ventures Using Chinese and Foreign Investment” to reinvest their profits in RMB in the domestic enterprises so as to enable them to earn foreign exchange.After being approved by the State Foreign Exchange Control Administration and agreed by the partners, one foreign investor can set up more than two Sino-foreign joint ventures within Chinese territory and coordinate foreign exchanges among these enterprises.If the above-listed measures fail to keep the balance, the joint ventures may apply to the approving Chinese organization which will coordinate accordingly.Apart from products whose prices may be based on those of their counterparts on international markets with the approval of the price control department, the prices of their products sold in China should be fixed on the basis of quality in line with the price regulations set by the state and be charged in RMB. The sales prices should be reported to relevant authoritative department and the price control department for record. The prices of their export products are decided by the joint venture enterprises themselves and are reported to the relevant authoritative department and the price control department for record.1. Which of the following can NOT be done by a Sino-foreign joint venture?A.Exporting their products.B.Earning foreign exchange.C.Selling all of their products in China.D.Balancing their foreign exchange income and expenditure.2. What kind of products can be sold in China by Sino-foreign joint ventures?A.Products short in supply in China.B.China’s traditional products.C.China’s traditional exports.D.The same products as those made in China.3.______ is one of the ways to balance the foreign exchange income and expenditure of joint ventures.A.Buying goods in ChinaB.Investing in ChinaC.Selling goods in ChinaD.Importing products from abroad4. The Ministry of Foreign Economic Relations and Trade controls ______.A.the management of a Sino-foreign joint ventureB.the production of a Sino-foreign joint ventureC.the sales of a Sino-foreign joint ventureD.the export of goods bought in China5.
