in this part.Each passage is followed by some questions orunfinished statements.For each of them there are four choices marked AJ,B,C and D,You should decide on the best choice and mark the corresponding letter on the AnswerSheet with a single line through the centre.Passage OneQuestions 21 to 25 are based on the following passage.With the prospect of coal and petroleum supplies depleted and with air pollution becoming asincreasing concern,the major countries of the world are seeking alternate sources of energy.If ameans to obtain energy from water,especially from the ocean,can be effected economically,itwould furnish a never ending supply of energy,since 70%of the earthVs surface is ocean andanother 10%is fresh water in rivers and lakes.From the beginning of time man has used water power as a source of work waterfalls and dams一 but these are fresh water sources and are landlocked.The seas have contributed little or nothingin the way of power.The use of temperature variation between currents is one area of exploration.Ocean water is heated by the sun near the equator and drawn by the rotation of the earth towardthe poles,where it cools and drops toward the ocean floor and starts its journey back toward theequator.The differential（差另!）between the two currents is 35 degrees to 45 degrees Fahrenheitand to use it the scientists must find the places where they run near land and are not too far awayfrom each other.One area that meets these requirements is the Caribbean Sea.Oceans also offer wave power,tides and the chemical propensities（倾向）of salt water as potentialsources of energy.All these uses are theoretically possible.BritainVs Department of Energy isinterested in wave power,using a string of tear drop devices that depend on very active waveareas and 100 feet depths.In addition to this,the British are working on a method that theJapanese have already put into practical use on a small scale for powering their navigational buoys.This method is called an oscillating（震荡）water column and rides the waves with a series ofcylinders having one-way air valves.Wave movement produces air under pressure that has onlyone escape route to a turbine（涡轮）that powers a generator.21.According to the first two p a r a g r a p h s,.A the use of water is a completely new conceptB the sea has long been used as a way of powerC water is a source of energy far more economical than any other energiesD water,if properly handled,may present a promising solution to energy crisis22.The word depleted(Line 1,Para.1)possibly means A exhausted B discarded C polluted DJ disappeared23.According to the passage,the Caribbean Sea is a place wh e r e.A two currents of different temperatures run near to each other and not far away from landBJ two currents of different temperatures run near to each other but far away from landfC the ocean water is heated by the sunfD the ocean water gets cool24.We can learn from the passage t hat.A as far as energy source is concerned,salt water is useless because of its chemical propertiesfB the working principle of a vibrating water column is to use water as a direct power driving ageneratorCJ Britain is pursuing a method that the Japanese have already put into practiceD Britain is the most advanced country in developing new energy source25.What is the passage mainly about?A Energy crisis.B Water as a possible solution to energy crisis.fC History of the use of water as a source of work energy.fD Properties of water.D Auto designers.Passage TwoQuestions 26 to 30 are based on the following passage.We have emphasized so far the significance of scarcity the limited means to satisfy humanwants.Because of scarcity,choices are necessary.An easy example of the problem of choice is apersonVs decision about how to allocate his or her time.As the old saying goes,“There are only24 hours in a day.If we take off 8 hours for a reasonable nights sleep,this leaves 16 hours to beallocated among all other possible things working at one or more jobs,watching TV,studying,playing tennis,etc.one can do with the limited available waking hours.Clearly,each personmust make choices about how much of their limited available time will be spent on each possibleactivity.When choices are made among alternatives such as those just described,it becomes plain thatchoosing one alternative often involves giving up another.For example,suppose you go to classes4 hours a day and get 8 hours of sleep.You will have an additional 12 waking hours to allocateper day.Suppose now that the only other activities you view as worth pursuing are watching TVand studying.If you choose to watch TV for 12 hours a day,no time will be left for studying,assuming you continue to sleep for 8 hours in each 24-hour period and do not cut classes.If youchoose each day to devote 6 hours to studying,only 6 of the 12 waking hours will be available forwatching TV.You must give up the opportunity of watching more hours of TV in the process ofchoosing to study.We can therefore say that the decision to study costs you 6 hours of TVwatching.Economists use the term opportunity cost to mean the cost of a specific choice measured interms of the next best alternative choice.In other words,it is what the decision maker must foregoin order to make the choice that is finally made.Thus,in our example,the opportunity cost ofstudying for 6 hours was 6 hours of watching TV.We can see many other examples of opportunitycosts around us.For example,governments are faced with limited budgets and therefore withlimited resources that can be used to provide goods and services to citizens.If a governmentchooses to improve its military forces,it may well do so by allocating fewer resources for librariesor schools.The opportunity cost of a strong defense may be a reduction in the size of libraryholdings or educational services.26.What is most probably the key point discussed immediately before this passage?A Limited time.B Making choices.CJ Opportunity cost.DJ The shortage of resources.27.According to the passage,choices must be made b e c a u s e.A resources are abundant(BJ there is too much for us to doC there are only 24 waking hours in a dayD our means are limited,but our wants are unlimited28.According to the passage,economists define opportunity cost as A an opportunity given up in terms of cashB the cost of a better choice measured in terms of cash:C giving up a specific choice for the next best alternativeD the cost of a specific choice measured in terms of any alternative choice29.In the examples cited in the passage,the opportunity cost of studying for 4 hours per daywas.A 4 hours of watching TV（B 4 hours of classesC 4 hours of sleep D 8 hours of sleep30.If a government chooses to allocate more of its resources to its military forces,there is apossibility of reduction in resources allocated for.A libraries and education B libraries and business firmsCJ education and business firms D libraries,business firms and educationPassage ThreeQuestions 31 to 35 are based on the following passage.Going online is a favorite recreation for millions of American children.Almost 10 million（14percent）of AmericaVs 69 million children are online.The Internet both entertains and educateschildren,however,there are some possible negative consequences for children who accesskid-based Web sites.Advertising on kid-based Web sites has become both a rapidly growingmarket for consumer companies and a concern for parents.With a click on an icon,children canlink to advertisers and be granted tremendous spending power.Children are an important targetgroup for consumer companies.Children under age 12 spent$14 billion,teenagers another$67billion,and together they influenced$160 billion of their parentsV incomes.Many critics question the appropriateness of targeting children in Internet advertising and press torequire that children be treated as a“special case by advertisers.Because children lack theanalytical（分析的）abilities and judgment of adults,they may be unable to evaluate the accuracyof information they view,or understand that the information they provide to advertisers is reallyjust data collected by an advertiser.Children generally lack the ability to give consent to therelease of personal information to an advertiser,an even greater problem for children when theyare offered incentives（刺激）for providing personal information,or when personal information isrequired before they are allowed to register for various services.Children may not realize that inmany cases these characters provide hotlinks directly to advertising sites.The Internet does present some challenges for advertisers who want to be ethical in theirmarketing practices.Many advertisers argue that we underestimate（低估）the levels of mediaawareness shown by children.By the age of seven or eight most children can recognize anadvertisement and know that its purpose is to sell something and are able to make judgments aboutthe products shown in advertisements.However,this somewhat optimistic and decidedlylibertarian view of children runs aground when we realize that they are（like a surprising numberof adults）unable to judge accurately between entertainment and advertising.Adults can fend forthemselves but,as marketers,we should be explicit（明确的）about our purpose when advertisingto children on the Internet.31.According to the first paragraph,children as an Internet ma r k e t.（Al are becoming increasingly rationalBl are using it at an earlier and earlier ageC has created a growing advertising marketD are overtaking the adult market due to their spending power32.Targeting children for advertising is controversial because c h i l d r e n.A are unable to analyze and judge advertisementsB are unable to give consent since they are too youngCl often give off information that may be dangerous to themfD are not ready to evaluate advertisements or information requests33.Many advertisers defend the targeting of children b e c a u s e.fA no actual sales take placefB it is up to parents to monitor their childrenCJ children understand what an advertisement is trying to doD children are provided a game in return for the information34.One reason why children are unable to resist giving personal information on the Internet is thatA the
