Answer the questions below each text by choosing A, B, C or D. (40 points)20 Someday a stranger will read your e-mail without yo

11、ur permission or scan the Website youve visited. Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits.In fact, its likely some of these things have already happened to you. Who would watch you without y

12、our permission? It might be a spouse, a girl friend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen the 21st century equivalent of being caught naked.Psychologists tell us boundaries are healthy, that its important to reveal

13、yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs(碎屑)you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think.

14、 Like it or not, increasingly we live in a world where you simply cannot keep a secret.The key question is: Does that matter?For many Americans, the answer apparently is“no.“When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey found an overwhelming pe

15、ssimism about privacy, with 60 percent of respondents saying they feel their privacy is“slipping away, and that bothers me.“But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollb

16、ooths(收费站)to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acauisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on

17、 a pitiful 50-cents-off coupon(优惠券).But privacy does matter at least sometimes. Its like health: When you have it, you dont notice it. Only when its gone do you wish youd done more to protect it.21 What does the author mean by saying “the 21st century equivalent of being caught naked“(Lines 3-4, Par

18、a. 2)?（A）Peoples personal information is easily accessed without their knowledge.（B） In the 21st century people try every means to look into others secrets.（C） People tend to be more frank with each other in fhe information age.（D）Criminals are easily caught on the spot with advanced technology.22 W

19、hat would psychologists advise on the relationships between friends?（A）Friends should open their hearts to each other.（B） Friends should always be faithful to each other.（C） There should be a distance even between friends.（D）There should be fewer disputes between friends.23 Why does the author say “

20、we live in a world where you simply cannot keep a secret“(Line5, Para. 3)?（A）Modern society has finally evolved into an open society.（B） People leave traces around when using modern technology.（C） There are always people who are curious about others affairs.（D）Many search engines profit by revealing

21、 peoples identities.24 What do most Americans do with regard to privacy protection?（A）They change behaviors that might disclose their identity.（B） They use various loyalty cards for business transactions.（C） They rely more and more on electronic devices.（D）They talk a lot but hardly do anything abou

22、t it.25 According to the passage, privacy is like health in that _.（A）people will make every effort to keep it（B） its importance is rarely understood（C） it is something that can easily be lost（D）people dont cherish it until they lose it25 Sustainable development is applied to just about everything f

23、rom energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use. This is especially true in agriculture, where sustainable development is often taken as the sole measure of progress without

24、 a proper appreciation of historical and cultural perspectives.To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so. Medieval agriculture in northern Europe fed, clothed and sheltered a predominantly rural socie

25、ty with a much lower population density than it is today. It had minimal effect on biodiversity, and any pollution it caused was typically localized. In terms of energy use and the nutrients(营养成分)captured in the product it was relatively inefficient.Contrast this with farming since the start of the

26、industrial revolution. Competition from overseas led farmers to specialize and increase yields. Throughout this period food became cheaper, safer and more reliable. However, these changes have also led to habitat(栖息地)loss and to diminishing biodiversity.Whats more, demand for animal products in deve

27、loping countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050. Yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions.All this means that agriculture in the 21st century will have to be very

28、 different from how it was in the 20th. This will require radical thinking. For example, we need to move away from the idea that traditional practices are inevitably more sustainable than new ones. We also need to abandon the notion that agriculture can be “ zero impact“. The key will be to abandon

29、the rather simple and static measures of sustainability, which centre on the need to maintain production without increasing damage.Instead we need a more dynamic interpretation, one that looks at the pros and cons(正反两方面)of all the various ways land is used. There are many different ways to measure a

30、gricultural performance besides food yield; energy use, environmental costs, water purity, carbon footprint and biodiversity. It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting. Bu

31、t we do not know whether lower carbon footprints will always be better for biodiversity.What is crucial is recognizing that sustainable agriculture is not just about sustainable food production.26 How do people often measure progress in agriculture?（A）By its productivity.（B） By its sustainability.（C

32、） By its impact on the environment.（D）By its contribution to economic growth.27 Specialization and the effort to increase yields have resulted in_.（A）localized pollution（B） the shrinking of farmland（C） competition from overseas（D）the decrease of biodiversity28 What does the author think of tradition

33、al farming practices?（A）They have remained the same over the centuries.（B） They have not kept pace with population growth.（C） They are not necessarily sustainable.（D）They are environmentally friendly.29 What will agriculture be like in the 21st century?（A）It will go through radical changes.（B） It wi

34、ll supply more animal products.（C） It will abandon traditional farming practices.（D）It will cause zero damage to the environment.30 What is the authors purpose in writing this passage?（A）To remind people of the need of sustainable development.（B） To suggest ways of ensuring sustainable food producti

35、on.（C） To advance new criteria for measuring farming progress.（D）To urge people to rethink what sustainable agriculture is.30 Wild Bill Donovan would have loved the Internet. The American spymaster who built the Office of Strategic Services in World War II and later laid the roots for the CIA was fa

36、scinated(使着迷)with information. Donovan believed in using whatever tools came to hand in the “ great game“ of espionagespying as a “profession“. These days the Net, which has already re-made such everyday pastimes as buying books and sending mail, is reshaping Donovans vocation as well.The latest rev

37、olution isnt simply a matter of gentlemen reading other gentlemens e-mail. That kind of electronic spying has been going on for decades. In the past three or four years, the World Wide Web has given birth to a whole industry of point-and-click spying. The spooks(间谍)call it “open-source intelligence“

38、 , and as the Net grows, it is becoming increasingly influential. In 1995 the CIA held a contest to see who could compile the most data about Burundi. The winner, by a large margin, was a tiny Virginia company called Open Source Solutions, whose clear advantage was its mastery of the electronic worl

39、d.Among the firms making the biggest splash in this new world is Straitford, Inc. , a private intelligence-analysis firm based in Austin, Texas. Straitford makes money by selling the results of spying(covering nations from Chile to Russia)to corporations like energy-services firm McDermott Internati

40、onal. Many of its predictions are available online at www. straitford. com.Straiford president George Friedman says he sees the online world as a kind of mutually reinforcing tool for both information collection and distribution, a spymasters dream. Last week his firm was busy vacuuming up data bits

41、 from the far corners of the world and predicting a crisis in Ukraine. “As soon as that report runs, well suddenly get 500 new Internet sign-ups from Ukraine, “ says Friedman, a former political science professor. “And well hear back from some of them. “ Open-source spying does have its risks, of co

42、urse, since it can be difficult to tell good information from bad. Thats where Straitford earns its keep.Friedman relies on a lean staff of 20 in Austin. Several of his staff members have military-intelligence backgrounds. He sees the firms outsider status as the key to its success. Straitfords brie

43、fs dont sound like the usual Washington back-and-forthing, whereby agencies avoid dramatic declarations on the chance they might be wrong. Straitford, says Friedman, takes pride in its independent voice.31 The emergence of the Net has_.（A）received support from fans like Donovan（B） remolded the intel

44、ligence services（C） restored many common pastimes（D）revived spying as a profession32 Donovans story is mentioned in the text to_.（A）introduce the topic of online spying（B） show how he fought for the U. S.（C） give an episode of the information war（D）honor his unique services to the CIA33 The phrase “

45、making the biggest splash“(Para. 3)most probably means_.（A）causing the biggest trouble（B） exerting the greatest effort（C） achieving the greatest success（D）enjoying the widest popularity34 It can be learned from paragraph 4 that_.（A）Straitfords prediction about Ukraine has proved true（B） Straitford g

46、uarantees the truthfulness of its information（C） Straitfords business is characterized by unpredictability（D）Straitford is able to provide fairly reliable information35 Straitford is most proud of its_.（A）official status（B） nonconformist image（C） efficient staff（D）military background35 Could the bad

47、 old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $ 10 last December. This near-tripling of oil prices calls up scary(可怕的)memories of the 1973 oil shock, when prices quadrupled(成四倍

48、), and 19791980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time?The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economi

49、c growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term.Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so ev
