2、rivate businessmen,striving to makeprofits,produce these goods and services in competition with other businessmen;and the profit motive,operating under competitive pressures,largely determines how these goods and services are produced.Thus,in the American economic system it is the demand of individu
3、al consumers,coupled with thedesire of businessmen to maximize profits and the desire of individuals to maximize their incomes,thattogether determine what shall be produced and how resources are used to produce it.An important factor in a market-oriented economy is the mechanism by which consumer de
4、mandscan be expressed and responded to by producers.In the American economy,this mechanism is providedby a price system,a process in which prices rise and fall in response to relative demands of consumersand supplies offered by sellerproducers.If the product is in short supply relative to the demand
5、,the pricewill be bid up and some consumers will be eliminated from the market.If,on the other hand,producingmore of a commodity results in reducing its cost,this will tend to increase the supply offered byseller-producers,which in turn will lower the price and permit more consumers to buy the produ
6、ct.Thus,price is the regulating mechanism in the American economic system.The important factor in a private-enterprise economy is that individuals are allowed to ownproductive resources(private property),and they are permitted to hire labor,gain control over naturalresources,and produce goods and se
7、rvices for sale at a profit.In the American economy,the concept ofprivate property embraces not only the ownership of productive resources but also certain rights,including the right to deteiTnine the price of a product or to make a free contract with another privateindividual.51.In Line 7,Para.1,th

12、e of these credit cards can be readautomatically,making it possible to withdraw or deposit money in scattered locations,whether or not thelocal branch bank is open.For many of us the cashless society is not on the horizon its alreadyhere.While computers offer these conveniences to consumers,they hav
13、e many advantages for sellers too.Electronic cash registers can do much more than simply ring up sales.They can keep a wide range ofrecords,including who sold what,when,and to whom.This information allows businessmen to keeptrack of their list of goods by showing which items are being sold and how f
14、ast they are moving.Decisions to reorder or return goods to suppliers can then be made.At the same time these computersrecord which hours are busiest and which employees are the most efficient,allowing personnel andstaffing assignments to be made accordingly.And they also identify preferred customer
15、s for promotionalcampaigns.Computers are relied on by manufacturers for similar reasons.Computer-analyzed marketingreports can help to decide which products to emphasize now,which to develop for the future,and whichto drop.Computers keep track of goods in stock,of raw materials on hand,and even of t

20、ldren are different in some significant way from others of the same age.For thesechildren to develop to their full adult potential,their education must be adapted to those differences.Although we focus on the needs of exceptional children,we find ourselves describing theirenvironment as well.While t
21、he leading actor on the stage captures our attention,we are aware of theimportance of the supporting players and the scenery of the play itself.Both the family and the society inwhich exceptional children live are often the key to their growth and development.And it is in the publicschools that we f
22、ind the full expression of societys understanding-the knowledge,hopes,and fearsthat are passed on to the next generation.Education in any society is a miiTor of that society.In that mirror we can see the strengths,theweaknesses,the hopes,the prejudices,and the central values of the culture itself.Th
23、e great interest inexceptional children shown in public education over the past three decades indicates the strong feeling inour society that all citizens,whatever their special conditions,deserve the opportunity to fully developtheir capabilities.All men are created equal.*Weve heard it many times,
24、but it still has important meaning foreducation in a democratic society.Although the phrase was used by this countrys founders to denoteequality before the law,it has also been interpreted to mean equality of opportunity.That concept implieseducational opportunity for all children the right of each
25、child to receive help in learning to the limitsof his or her capacity,whether that capacity be small or great.Recent court decisions have confirmed theright of all children-disabled or not-to an appropriate education,and have ordered that publicschools take the necessary steps to provide that educat
26、ion.In response,schools are modifying theirprograms,adapting instruction to children who are exceptional,to those who cannot profit substantiallyfrom regular programs.59.In paragrah 2.the author cites the example of the leading actor on the stage to show that.A the growth of exceptional children has
27、 much to do with their family and the societyB exceptional children are more influenced by their families than normal children areC exceptional children are the key interest of the family and societyD the needs of the society weigh much heavier than the needs of the exceptional children60.The reason
28、 that the exceptional children receive so much concern in education is that.IAJ they are expected to be leaders of the societyB they might become a burden of the societyIC they should fully develop their potentialsD disabled children deserve special consideration61.This passage mainly deals wi t h.A
29、 the differences of children in their learning capabilitiesB the definition of exceptional children in modern societyC the special educational programs for exceptional childrenD the necessity of adapting education to exceptional children62.From this passage we learn that the educational concern for
30、exceptional c h i l d r e n.(AJ is now enjoying legal supportB disagrees with the tradition of the countryC was clearly stated by the countrys foundersD will exert great influence over court decisionsPassage 4HI have great confidence that by the end of the decade well know in vast detail how cancer
31、cellsarise,says microbiologist Robert Weinberg,an expert on cancer.But,he cautions,Hsome people havethe idea that once one understands the causes,the cure will rapidly follow.Consider Pasteur,hediscovered the causes of many kinds of infections,but it was fifty or sixty years before cures wereavailab
32、le.This year,50 percent of the 910,000 people who suffer from cancer will survive at least five years.In the year 2000,the National Cancer Institute estimates,that figure will be 75 percent.For some skincancers,the five-year survival rate is as high as 90 percent.But other survival statistics are st
33、illdiscouraging-13 percent for lung cancer,and 2 percent for cancer of the pancreas.With as many as 120 varieties in existence,discovering how cancer works is not easy.Theresearchers made great progress in the early 1970s,when they discovered that oncogenes,which arecancer-causing genes,are inactive
34、 in normal cells.Anything from cosmic rays to radiation to diet mayactivate a dormant oncogene,but how remains unknown.If several oncogenes are driven into action,thecell,unable to turn them off,becomes cancerous.The exact mechanisms involved are still mysterious,but the likelihood that many cancers
35、 areinitiated at the level of genes suggests that we will never prevent all cancers.Changes are a normal partof the evolutionary process,1 says oncologist William Hayward,Environmental factors can never betotally eliminated;as Hayward points out,*We cant prepare a medicine against cosmic rays.The pr
36、ospects for cure,though still distant,are brighter.First,we need to understand how the normal cell controls itself,Second,we have to determinewhether there are a limited number of genes in cells which are al-ways responsible for at least part of thetrouble.If we can understand how cancer works,we ca
37、n counteract its action.63.The example of Pasteur in the passage is used to.A predict that the secret of cancer will be disclosed in a decadeB indicate that the prospects for curing cancer are brightCJ prove that cancer will be cured in fifty to sixty yearsD warn that there is still a long way to go
38、 before cancer can be conquered64.The author implies that by the year 2000,.A there will be a drastic rise in the five-year survival rate of skin-cancer patientsB 90 percent of he skin-cancer patients today will still be livingC the survival statistics will be fairly even among patients with various
39、 cancersD there won t be a drastic increase of survival rate of all cancer patients65.Oncogenes are cancer-causing genes.A that are always in operation in a healthy personB which remain unharmful so long as they are not activatedC that can be driven out of normal cellsIDJ which normal cell can*t tur
40、n off66.The word dormant in the third paragraph most probably me ans.A dead B ever-present C inactive D potentialPassage 5Discoveries in science and technology are thought by untaught minds to come in blinding flasheror as the result of dramatic accidents.Sir Alexander Fleming did not,as legend woul
41、d have it,look at themold on a piece of cheese and get the idea for penicillin there and then.He experimented withantibacterial substances for nine years before he made his discovery.Inventions and innovations almostalways come out of laborious trial and error.Innovation is like soccer;even the best
42、 players miss thegoal and have their shots blocked much more frequently than they score.They point is that the players who score most are the ones who take the most shots at the goalandso it goes with innovation in any field of activity.The prime difference between innovators and others isone of app
43、roach.Everybody gets ideas,but innovators work consciously on theirs,and they follow themthrough until they prove practicable or otherwise.What ordinary people see as fanciful abstractions,professional innovators see as solid possibilities.Creative thinking may mean simply the realization that there
44、s no particular virtue in doing thingsthe way they have always been done,wrote Rudolph Flesch,a language authority.This accounts for ourreaction so seemingly simple innovations like plastic garbage bags and suitcases on wheels that makelife more convenient:How come nobody thought of that before?The
45、creative approach begins with the proposition that nothing is as it appears.Innovators will notaccept that there is only one way to do anything.Faced with getting from A to B,the average person willautomatically set out on the best-known and apparently simplest route.The innovator will search foralt
46、ernate courses,which may prove easier in the long run and are bound to be more interesting andchallenging even if they lead to dead ends.Highly creative individuals really do march to a different drummer.67.What does the author probably mean by untaught mind in the first paragraph?A A person ignoran
47、t of the hard work involved in experimentation.B A citizen of a society that restricts personal creativity.C A person who has had no education.DI An individual who often comes up with new ideas by accident.68.According to the author,what distinguishes innovators from non-innovators?AJ The variety of
48、 ideas they have.B The intelligence they possess.C The way they deal with problems.D The way they present their findings.69.The author quotes Rudolph Flesch in Paragraph 3 b e c a u s e.A Rudolph Flesch is the best-known expert in the study of human creativityB the quotation strengthens the assertio
49、n that creative individuals look for new ways of doingthingsCJ the reader is familiar with Rudolph Flesch*s point of viewD the quotation adds a new idea to the information previously presented70.The phrase march to a different drummer1(the last line of the passage)suggests that highly creativeindivi
50、duals are.IAJ diligent in pursuing their goalsB reluctant to follow common ways of doing thingsIC devoted to the progress of scienceD concerned about the advance of societyUnit 2Passage 1Money spent on advertising is money spent as well as any I know of.It serves directly to assist arapid distributi
