2、xt by choosing A,B,C or D.Text 1 Every profession or trade,every art,and every science has its technical vocabulary,the function of which is partly to refer to things or processes which have no names in ordinary English,and partly to secure greater exactness in nomenclature.Such special dialects,or

3、jargon,are necessary in technical discussion of any kind.Being universally understood by the devotees of the particular science or art,they have the precision of a mathematical formula.Besides,they save time,for it is much more economical to name a process than to describe it.Thousands of these tech

4、nical terms are very properly included in every large dictionary,yet,as a whole,they are rather on the outskirts of the English language than actually within its borders.Different occupations,however,differ widely in the character of their special vocabularies.In trades and handicrafts and other occ

5、upations,such as farming and fishing,that have occupied great numbers of men from remote times,the technical vocabulary is very old.It consists largely of native words,or of borrowed words that have worked themselves into the very fiber of our language.Hence,though highly technical in many particula

6、rs,these vocabularies are more familiar in sound,and more generally understood than most other technicalities.The special dialects of law,medicine,divinity,and philosophy have also,in their older strata,become pretty familiar to cultivated persons,and have contributed much to the popular vocabulary.

7、Yet,every vocation still possesses a large body of technical terms that remain essentially foreign,even to educated speech.And the proportion has been much increased in the last fifty years,particularly in the various departments of natural and political sciences and in the mechanic arts.Hence new t

8、erms are coined with the greatest freedom,and abandoned with indifference when they have served their turn.Most of the new coinages are confined to special discussions and seldom get into general literature or conversation.Yet no profession is nowadays,as all profession once were,a closed guild.The

9、lawyer,the physician,the man of science,and the cleric associate freely with his fellow creatures,and does not meet them in a merely professional way.Furthermore,what is called popular science makes everybody acquainted with modern views and recent discoveries.Any important experiment,though made in

10、 a remote or provincial 学英语 找长喜 2 laboratory,is at once reported in the newspapers,and everybody is soon talking about it as in the case of the Roentgen rays and wireless telegraphy.Thus,our common speech is always taking up new technical terms and making them commonplace.1.The last sentences in par

11、agraph 1 shows that technical terms A are used in the urban areas.B are used in the rural areas.C are not the core of common speech.D are not understood by common people.2.What can be inferred from paragraph 2 and 3?A Technical terms from remote times are too old for us to understand today.B Special

12、 dialects of law,medicine and so on are restricted to cultivated people C The words of the English language have changed a lot in the last fifty years.D One can never be sure what a word means without consulting an expert.3.The sentence“Yet no professionsclosed guilds”means that A it is much easier

13、to become a professional today than it was.B there is more communication between professionals and others.C popular science has told her secrets to the world.D anyone can now understand anything in a profession.4.Roentgen rays and wireless telegraphy are mentioned to show A rapid occurrence of jargo

14、n.B rapid disappearance of jargon.C precision of jargon in meaning.D popular familiarity with jargon.5.Whats the authors main purpose in writing this text?A to describe a phenomenon.B to argue about a belief.C to propose a solution.D to stimulate an action.Text 2 Computer programmers often remark th

15、at computers,with a perfect lack of discrimination,will do any foolish thing they are told to do.The reason for this lies,of course,in the narrow fixation of the computers“intelligence”on the details of its own perceptions and in its inability to be guided by any large context.In a psychological des

16、cription of the computer intelligence,three related adjectives come to mind:single-minded,literal-minded,and simple-minded.Recognizing this,we should at the same time recognize that this single-mindedness,literal-mindedness,and simple-mindedness also characterizes theoretical mathematics,though to a

17、 lesser extent.Since science tries to deal with reality,even the most precise sciences normally work with more or less imperfectly understood approximations toward which scientists must maintain an appropriate skepticism.Thus,for instance,mathematicians may be surprised to learn that the Sehrodinger

18、 equation for the hydrogen atom is not a literally correct description of this atom but only an approximation to a somewhat more correct equation which takes account of spin,magnetic dipole,and relativistic effects.They may also be shocked to see this corrected equation is itself only an imperfect a

19、pproximation to an infinite set of quantum field theoretical equations.Physicists,looking at the original Sehrodinger equation,learn to sense in it the presence of many invisible terms in addition to the differential terms visible,and this sense inspires an entirely appropriate disregard for the pur

20、ely technical features of the equation.This very healthy skepticism is foreign to the mathematical approach.学英语 找长喜 3 Mathematics must deal with well-defined situations.Thus,mathematicians depend on an intellectual effort outside of mathematics for the crucial specification of the approximation that

21、 mathematics is to take literally.Give mathematicians a situation that is the least bit ill-defined,and they will make it well-defined,perhaps appropriately,but perhaps inappropriately.In some cases,the mathematicians literal-mindedness may have unfortunate consequences.The mathematicians turn the s

22、cientists theoretical assumptions,that is,their convenient points of analytical emphasis into axioms,and then take these axioms literally.This brings the danger that they may also persuade the scientists to take these axioms literally.The question,central to the scientific investigation but intensel

23、y disturbing in the mathematical contextwhat happens if the axioms are relaxed?is thereby ignored.The physicist rightly dreads precise argument,since an argument that is convincing only if it is precise loses all its force if the assumptions on which it is based are slightly changed,whereas an argum

24、ent that is convincing though imprecise may well be stable under small disturbances of its underlying assumptions.6.The author discusses computers in the first paragraph primarily in order to A prove that computers carry out tasks in a mechanical way.B discuss computers from the psychological terms

25、to explain its features.C compare the work of mathematicians with that of computer programmers.D illustrate his views about the approach of mathematicians to problem solving.7.Scientists are skeptical toward their equations because they A are unable to express their data in terms of multiple variabl

26、es.B know well-defined problems are often the most difficult to solve.C work to explain real,rather than theoretical or simplified situations.D are unable to accept mathematical explanations of natural phenomena.8.The author suggests that the approach of physicists to solving scientific problems is

27、A harmful to scientific progress.B practical for scientific purposes.C effective,but rarely recognized as such.D helpful,but of little long-term value.9.Why do mathematicians present a danger to scientists?A Scientists may come to believe that axiomatic statements are untrue.B Scientists may begin t

28、o provide imprecise but convincing arguments.C Mathematicians may convince scientists that theoretical assumptions are facts.D Scientists may define situations in an incomprehensible way to mathematicians.10.From the last paragraph,the assumption made by scientists about scientific arguments is that

29、 A the premises on which the arguments are based may change.B the arguments probably will be convincing only to other scientists.C the conclusions of the arguments do not necessarily follow from their premises.D the arguments necessarily ignore the central question of scientific investigation.Text 3

30、 There he wasAmericas first president with a MBA,the man who loves to boast about his business background,whose presidential campaign raised unprecedented sums from corporate 学英语 找长喜 4 wallets and whose cabinet is stuffed with chief executivesstanding before 700 pinstriped titans in a New York hotel

35、from a few bad-apple chief executives rather than the system as a whole.Hence his focus on tough penalties for corrupt businessmen and his plea for higher ethical standards.The president announced the creation of a“financial-crimes SWAT team”at the Justice Department to root out corporate fraud,and

36、wants to double the maximum prison sentence for financial fraud from five to ten years.But he offered few concrete suggestions for systemic reform:little mention of changes to strengthen shareholders rights,not even an endorsement of the Senate corporate-reform bill.There are few signs yet that clea

37、ning up corporate America is an issue that animates the voters.Polls show that Americans have little faith in their business leaders,but politicians do not seem to be suffering as a result.Mr.Bushs approval ratings have fallen from their sky-highs,but they are still very strong.The president,therefo

38、re,need do no more than talk tough.This alone will convince ordinary Americans that he is on top of the issue.As the economy rebounds and public outage subsides,the clamor for change will quieten.Democratic attacks will fizzle,and far-reaching reform bills will be watered down before they become law

39、.Politically,the gamble makes sense.Unfortunately for American capitalism,a great opportunity will be missed.11.Which of the following is true according to the first two paragraphs?A Mr.Bush has taken tough action to prohibit cooking the books.B Mr.Bush contributed a lot to a decade-long economic bo

42、tions for reform as political pressure increases.学英语 找长喜 5 B At present,the maximum prison sentence for financial fraud is five years.C It is laughable that Mr.Bush publicly attacked Americas corporate bosses.D Americans have little faith in their business as well as political leaders.14.The phrase“

43、a great opportunity”mentioned in the last paragraph refers to A an opportunity to carry out reform.B an opportunity to boom economy.C an opportunity to animate the voters.D an opportunity to attack chief executives.15.What is the authors attitude towards the reform?A Indifferent.B Optimistic.C Skept

44、ical.D Favorable.Text 4 The simple act of surrendering a telephone number to a store clerk may seem innocuousso much so that many consumers do it with no questions asked.Yet that one action can set in motion a cascade of silent events,as that data point is acquired,analyzed,categorized,stored and so

48、quences that flow from simple actions make privacy issues difficult to grasp,and grapple with.In a larger sense,privacy also is often cast as a tale of“Big Brother”the government is watching you or a big corporation is watching you.But privacy issues dont necessarily involve large faceless instituti

49、ons.A spouse takes a casual glance at her husbands Blackberry,a co-worker looks at e-mail over your shoulder or a friend glances at a cell phone text message from the next seat on the bus.While very little of this is news to anyonepeople are now well aware there are video cameras and Internet cookie

50、s everywherethere is abundant evidence that people live their lives ignorant of the monitoring,assuming a mythical level of privacy.People write e-mails and type instant messages they never expect anyone to see.Just ask Mark Foley or even Bill Gates,whose e-mails were a cornerstone of the Justice De
