31.purpose 【解析】从文中的第一句话“The most obvious purpose...”可以看出后面还有别的目的，而不是仅仅有最明显的目的。故答案为purpose。

32.first 【解析】根据题意，作者想在这里做一个比较，而比较的对象是目的。这里作者仅仅给出了两个目的，所以这里是和第一个目的进行比较。故答案为first。

33.production【解析】从前一句话“The manufacturers go beyond only telling consumers about their products.”可以看出，一方面广告要介绍自己的产品，而第二个目的就是卖掉自己的产品。所以这里作者想要表达的意思是“广告要使得顾客有一种购买的欲望去购买自己的产品。”故答案为production。

34.for 【解析】解析见上题。desire后面用介词for。故答案为for，表示“…的欲望”。

35.bought 【解析】本句的前一句话说“顾客认为他们需要一些他们其实不需要的商品。”这就是广告的作用。但是买完之后，“他们却不知道当时为什么买了这种商品。”这里是被动的句式。故答案为bought。

36.though 【解析】本句话的意思是“尽管知道顾客们可能不知道自己为什么买了这些商品，但是卖家却知道怎么去做。”故答案为though。

37.do【解析】解析见上题，为了避免与前面的know重复，这里可以换做do。故答案为do。

38.selling 【解析】关键是看and后面的buying。本句话的意思是“商家分析市场的供需情况。”故答案为selling。

39.some 【解析】关键是注意and前后一致。“some rational and...emotional”，前面说促使顾客购买的动机有很多，有的是理性的，有的却是冲动。所以这里应该是some。故答案为some。

40.knowledge【解析】前面讲商家正确的分析市场的供需信息，知道是什么因素影响顾

客的购买欲望。这就是他们利用的信息知识。故答案为knowledge。

41.are 【解析】分析句子结构，这里缺少系动词be来构成动词的被动形式。故答案为ale。

42.reasons 【解析】本段的第一句话提出问题，问为什么在结算处摆设了那么多的商品。很明显，后面的文章对这个问题进行回答，并列举了原因。故答案为reasons。

43.ready 【解析】顾客来到结算处，说明他们准备好了要付账。be ready to的意思是“准备好了做某事”。故答案为ready。

44.on 【解析】“…的决定”英语表达为“decision on sth.”这里介词需要用on。故答案为on。

45.customer 【解析】从这个句子的宾语“…that he or she has done a good job of choosing the items.”可以看出，这里说的是顾客的行为，他们认为自己买这些商品是很理性的。故答案为customer。

46.display 【解析】这里要回应本段第一句话中的“displayed”。在出口结算处展示的这些小商品无疑是一种诱惑。这里需要用名词形式。故答案为display。

Why the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years-and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times-are questions which have interested the modern philosopher not less than the objects with which these sciences are more immediately conversant. Was it the employment of a new method of research, or in the exercise of greater virtue in the use of the old methods, that this singular modern phenomenon had its origin? Was the long period one of arrested development, and is the modern era one of normal growth? Or should we ascribe the characteristics of both periods to so-called historical accidents-to the influence of conjunctions in circumstances of which no explanation is possible, save in the omnipotence and wisdom of a guiding Providence?

The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the moderns employ induction, proves to be too narrow, and fails upon close examination to point with sufficient distinctness the contrast that is evident between ancient and modern scientific doctrines and inquiries. For all knowledge is founded on observation, and proceeds from this by analysis, by synthesis and analysis, by induction and deduction, and if possible by verification, or by new appeals to observation under the guidance of deduction-by steps which are indeed correlative parts of one method; and the ancient sciences afford examples of every one of these methods, or parts of one method, which have been generalized from the examples of science.

A failure to employ or to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts, by appeal to experiment and observation-these are the faults which cause all failures to ascertain truth, whether among the ancients or the moderns; but this statement does not explain why the modern is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent times.

The attempt to discover the explanation of this phenomenon in the antithesis of “facts”and “theories”or “facts”and “ideas”-in the neglect among the ancients of the former, and their too exclusive attention to the latter-proves also to be too narrow, as well as open to the charge

of vagueness. For in the first place, the antithesis is not complete. Facts and theories are not coordinate species. Theories, if true, are facts-a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories.

Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and connotes an important character in true method. A fact is a proposition of simple. A theory, on the other hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact.

The striving of countries in Central Europe to enter the European Union may offer an unprecedented chance to the continent’s Gypsies (or Roman) to be recognized as a nation, albeit one without a defined territory. And if they were to achieve that they might even seek some kind of formal place-at least a total population outnumbers that of many of the Union’s present and future countries. Some experts put the figure at 4m-plus; some proponents of Gypsy rights go as high as 15m.

Unlike Jews, Gypsies have had no known ancestral land to hark back to. Though their language is related to Hindi, their territorial origins are misty. Romanian peasants held them to be born on the moon. Other Europeans (wrongly) thought them migrant Egyptians, hence the derivative Gypsy. Most probably they were itinerant metal workers and entertainers who drifted west from India in the 7th century.

However, since communism in Central Europe collapsed a decade ago, the notion of Romanestan as a landless nation founded on Gypsy culture has gained ground. The International Romany Union, which says it stands for 10m Gypsies in more than 30 countries, is fostering the idea of “self-rallying”. It is trying to promote a standard and written form of the language; it waves a Gypsy flag (green with a wheel) when it lobbies in such places as the United Bations; and in July it held a congress in Prague, The Czech capital. Where President Vaclav Havel said that Gypsies in his own country and elsewhere should have a better deal.

At the congress a Slovak-born lawyer, Emil Scuka, was elected president of the International Tomany Union. Later this month a group of elected Gypsy politicians, including members of parliament, mayors and local councilors from all over Europe (OSCE), to discuss how to persuade more Gypsies to get involved in politics.

The International Romany Union is probably the most representative of the outfits that speak for Gypsies, but that is not saying a lot. Of the several hundred delegates who gathered at its congress, few were democratically elected; oddly, none came from Hungary, whose Gypsies are perhaps the world’s best organized, with some 450 Gypsy bodies advising local councils there. The union did, however, announce its ambition to set up a parliament, but how it would actually be elected was left undecided.

So far, the European Commission is wary of encouraging Gypsies to present themselves as a nation. The might, it is feared, open a Pandora’s box already containing Basques, Corsicans and other awkward peoples. Besides, acknowledging Gypsies as a nation might backfire, just when several countries, particularly Hungary, Slovakia and the Czech Republic, are beginning to treat them better, in order to qualify for EU membership. “The EU’s whole premise is to

overcome differences, not to highlight them,”says a nervous Eurocrat.

But the idea that the Gypsies should win some kind of special recognition as Europe’s largest continent wide minority, and one with a terrible history of persecution, is catching on . Gypsies have suffered many pogroms over the centuries. In Romania, the country that still has the largest number of them (more than 1m), in the 19th century they were actually enslaved. Hitler tried to wipe them out, along with the Jews.

“Gypsies deserve some space within European structures,”says Jan Marinus Wiersma, a Dutchman in the European Parliament who suggests that one of the current commissioners should be responsible for Gypsy affairs. Some prominent Gypsies say they should be more directly represented, perhaps with a quota in the European Parliament. That, they argue, might give them a boost. There are moves afoot to help them to get money for, among other things, a Gypsy university.

One big snag is that Europe’s Gypsies are, in fact, extremely heterogeneous. They belong to many different, and often antagonistic, clans and tribes, with no common language or religion, Their self-proclaimed leaders have often proved quarrelsome and corrupt. Still, says, Dimitrina Petrova, head of the European Roma Rights Center in Budapest, Gypsies’shared experience of suffering entitles them to talk of one nation; their potential unity, she says, stems from “being regarded as sub-human by most majorities in Europe.”

And they have begun to be a bit more pragmatic. In Slovakia and Bulgaria, for instance, Gypsy political parties are trying to form electoral blocks that could win seats in parliament. In Macedonia, a Gypsy party already has some-and even runs a municipality. Nicholas Gheorge, an expert on Gypsy affairs at the OSCE, reckons that, spread over Central Europe, there are now about 20 Gypsy MPS and mayors, 400-odd local councilors, and a growing number of businessmen and intellectuals.

That is far from saying that they have the people or the cash to forge a nation. But, with the Gypsy question on the EU’s agenda in Central Europe, they are making ground.

President Clinton’s decision on Apr.8 to send Chinese Premier Zhu Rongji packing without an agreement on China’s entry into the World Trade Organization seemed to be a massive miscalculation. The President took a drubbing from much of the press, which had breathlessly reported that a deal was in the bag. The Cabinet and Whit House still appeared divided, and business leaders were characterized as furious over the lost opportunity. Zhu charged that Clinton lacked “the courage”to reach an accord. And when Clinton later telephoned the angry Zhu to pledge a renewed effort at negotiations, the gesture was widely portrayed as a flip-flop.

In fact, Clinton made the right decision in holding out for a better WTO deal. A lot more horse trading is needed before a final agreement can be reached. And without the Administration’s goal of a “bullet-proof agreement”that business lobbyists can enthusiastically sell to a Republican Congress, the whole process will end up in partisan acrimony that could harm relations with China for years.

THE HARD PART. Many business lobbyists, while disappointed that the deal was not closed, agree that better terms can still be had. And Treasury Secretary Robert E. Rubin, National Economic Council Director Gene B. Sperling, Commerce Secretary William M. Daley, and top trade negotiator Charlene Barshefsky all advised Clinton that while the Chinese had made a remarkable number of concessions, “we’re not there yet,”according to senior officials.

Negotiating with Zhu over the remaining issues may be the easy part. Although Clinton can signal U.S. approval for China’s entry into the WTO himself, he needs Congress to grant Beijing permanent most-favored-nation status as part of a broad trade accord. And the temptation for meddling on Capital Hill may prove over-whelming. Zhu had barely landed before Senate Majority Leader Trent Lott (R-Miss) declared himself skeptical that China deserved entry into the WTO. And Senators Jesse A. Helms (R-N.C.) and Emest F. Hollings (D-S. C.) promised to introduce a bill requiring congressional approval of any deal.

The hidden message from these three textile-state Southerners: Get more protection for the U. S. clothing industry. Hoping to smooth the way, the Administration tried, but failed, to budge Zhu on textiles. Also left in the lurch: Wall Street, Hollywood, and Detroit. Zhu refused to open up much of the lucrative Chinese securities market and insisted on “cultural”restrictions on American movies and music. He also blocked efforts to allow U. S. auto makers to provide fleet financing.

BIG JOB. Already, business lobbyists are blanketing Capitol Hill to presale any eventual agreement, but what they’ve heard so far isn’t encouraging. Republicans, including Lott, say that “the time just isn’t right”for the deal. Translation: We’re determined to make it look as if Clinton has capitulated to the Chinese and is ignoring human, religious, and labor rights violations; the theft of nuclear-weapons technology; and the sale of missile parts to America’s enemies. Beijing’s fierce critics within the Democratic Party, such as Senator Paul D. Wellstone of Minnesota and House Minority leader Richard A. Gephardt of Missouri, won’t help, either.

Just how tough the lobbying job on Capitol Hill will be become clear on Apr. 20, when Rubin lectured 19chief executives on the need to discipline their Republican allies. With business and the White House still trading charges over who is responsible for the defeat of fast-track trade negotiating legislation in 1997, working together won’t be easy. And Republicans-with a wink-say that they’ll eventually embrace China’s entry into the WTO as a favor to Corporate America. Though not long before they torture Clinton. But Zhu is out on a limb, and if Congress overdoes the criticism, he may be forced by domestic critics to renege. Business must make this much dear to both its GOP allies and the Whit House: This historic deal is too important to risk losing to any more partisan squabbling.

On the 36th day after t hey had voted, Americans finally learned Wednesday who would be their next president: Governor George W. Bush of Texas.

Vice President Al Gore, his last realistic avenue for legal challenge closed by a U. S. Supreme Court decision late Tuesday, planned to end the contest formally in a televised evening speech of perhaps 10 minutes, advisers said.

They said that Senator Joseph Lieberman, his vice presidential running mate, would first make brief comments. The men would speak from a ceremonial chamber of the Old Executive office Building, to the west of the White House.

The dozens of political workers and lawyers who had helped lead Mr. Gore’s unprecedented fight to claw a come-from-behind electoral victory in the pivotal state of Florida were thanked Wednesday and asked to stand down.

“The vice president has directed the recount committee to suspend activities,”William Daley, the Gore campaign chairman, said in a written statement.

Mr. Gore authorized that statement after meeting with his wife, Tipper, and with top advisers including Mr. Daley.

He was expected to telephone Mr. Bush during the day. The Bush campaign kept a low profile and moved gingerly, as if to leave space for Mr. Gore to contemplate his next steps.

Yet, at the end of a trying and tumultuous process that had focused world attention on sleepless vote counters across Florida, and on courtrooms form Miami to Tallahassee to Atlanta to Washington the Texas governor was set to become the 43d U. S. president.

The news of Mr. Gore’s plans followed the longest and most rancorous dispute over a U. S. presidential election in more than a century, one certain to leave scars in a badly divided country.

It was a bitter ending for Mr. Gore, who had outpolled Mr. Bush nationwide by some 300000 votes, but, without Florida, fell short in the Electoral College by 271votes to 267-the narrowest Electoral College victory since the turbulent election of 1876.

Mr. Gore was said to be distressed by what he and many Democratic activists felt was a partisan decision from the nation’s highest court.

The 5-to -4 decision of the Supreme Court held, in essence, that while a vote recount in Florida could be conducted in legal and constitutional fashion, as Mr. Gore had sought, this could not be done by the Dec. 12 deadline for states to select their presidential electors.

James Baker 3rd, the former secretary of state who represented Mr. Bush in the Florida dispute, issued a short statement after the U. S. high court ruling, saying that the governor was “very pleased and gratified.”

Mr. Bush was planning a nationwide speech aimed at trying to begin to heal the country’s deep, aching and varied divisions. He then was expected to meet with congressional leaders, including Democrats. Dick Cheney, Mr. Bush’s ruing mate, was meeting with congressmen Wednesday in Washington.

When Mr. Bush, who is 54, is sworn into office on Jan.20, he will be only the second son of a president to follow his father to the White House, after John Adams and John Quincy Adams in the early 19th century.

Mr. Gore, in his speech, was expected to thank his supporters, defend his hive-week battle as an effort to ensure, as a matter of principle, that every vote be counted, and call for the nation to join behind the new president. He was described by an aide as “resolved and resigned.”

While some constitutional experts had said they believed states could present electors as late as Dec. 18, the U. S. high court made clear that it saw no such leeway.

The U.S. high court sent back “for revision”to the Florida court its order allowing recounts but made clear that for all practical purposes the election was over.

In its unsigned main opinion, the court declared, “The recount process, in its features here described, is inconsistent with the minimum procedures necessary to protect the fundamental right of each voter.”

For most of us today, television is our main source of news. According to a questionnaire on the way of getting news ,nearly 72 percent of the people watch TV, and only 12 percent read newspapers for daily news. Although television news excels in bringing into our living room dramatic events of singular importance, space craft launchings, natural disasters, record-breaking sports events, presidential inaugurations, wars, murders and so on, it cannot cover important stories in the depth they may deserve because of its time limitations. Regardless of the complexity or significance of an event, it some how must be fitted into a prescribed number of minutes. On the other hand, while the newspaper cannot compete with television visually, for example, a war is

often best communicated by pictures, not words, it may beat its rival with amore in-depth version of the event. Free of time restrictions imposed on television news, a newspaper can devote as much space to a story as it sees fit, and flesh it out with more vivid details.

Furthermore, television by nature is a passive medium, for it deprives viewers of the freedom of selection. Whether you like or dislike a particular piece of news, all you have to do is sit in front of the tube and let it happen and follow its space passively. But by reading newspapers, you can select the most interesting news, and skip what you think is irrelevant and dull; you can read in detail or briefly. Besides, watching television involves little mental activity. A constant diet of television journalism contributes to the rise in new illiteracy ,and the decline in general intellectual skills such as reading and writing. In contrast to television news, the print media encourage active involvement in what’s being reported. The readers have to make greater efforts than TV viewers to follow and absorb the stories. But they acquire more than information and news. Reading requires high level of mental involvement, which, in turn, improves our intellectual competence. When we consider television versus print journalism on the basis of format, coverage and nature, is there any question as to which is the better source of news?

31.someone 【解析】由本文的第一句话“‘Down-to-earth’means some—one or something that is honest，realistic and easy to deal with.”可知“Down—to—earth”指的是诚实，现实、平易近人的那些人。这里的someone和后面是相对应的。故答案为someone。

32.to【解析】talk to的意思是“和某人聊天”，talk这里不及物动词，后面需要接一个介词。在从句中介词不能省略。作者这里要表达的意思是“和那些诚实的平易近人的人聊天是很惬意的。”故答案为to。

33.opposite 【解析】从文章第二段的内容可以看出，A down—to—earth person和那些表面上装的很重要的人物正好相反。所以这里应填“相反的”，故答案为opposite。

34.important 【解析】从本句后面的一句话可以看出，A down—to—earth person就算是重要的人物，他们也不会把这种显赫写在脸上。所以前面应填important。故答案为important。

35.go 【解析】go to one’s heads的意思是“展现、表现”，俗语。用在文中表示“把…写在脸上”，生怕别人不知道的显摆。故答案为go。

36.those 【解析】本句的意思是“他们不认为自己比别的不重要的人更好、更优秀。”这里比较的是down—to—earth persons和别人。故答案为those。

37.often 【解析】本句话的意思是“那些自我感觉很了不起、内心充满骄傲的人，总是不需要理由的就被人认为是趾高气扬的人。”故这里答案为often。

38.n0 【解析】本句话的意思是“那些趾高气扬的人不可能是那些平易近人的人”。这是否定的意思，故答案为no。

https://www.360docs.net/doc/266983644.html,e 【解析】后面的一句话“The expression is‘both—feet—on—the—ground.’”表示down—to—earth的另一种表达方法是both—feet.on—the—ground。而后一种说法是美国人的用法，常常被美国人使用。故答案为use。

40.with 【解析】根据对等关系，这里应该与后面的部分“a person with a good understanding”相对应。意思是“那些脚踏实地的人往往是那些很了解现实的人。”故答案为with。

41.of 【解析】“对现实的了解”的英文表达是“the understanding of reality”，这里的介词用of。故答案为of。

42.but 【解析】这里表达的前后句意是一种转折关系。前面说“he may have dreams，”而后面“he does not allow them to block his knowledge...”的意思却是“但是他也不会让这些梦想阻挡自己对什么是现实的理解。”故答案为but。

43.what 【解析】解析同上。这里是一个名词性从句，what在句中做主语。故答案为what。

44.person 【解析】本句话的意思是“与此相反的一类人是那些想入非非的人。”根据上下文的要求这里应该填入man的同义词。故答案为person。

45.whose 【解析】这是一个后置定语从句，用whose来引导，表示mind与dreamer 的所属系。故答案为whose。

46.Sometime【解析】通过对后面句子的分析，我们可以知道那些想人非非、飘飘欲仙的人有朝一日也是可以“双脚落地的”，那就是“sharp words from teacher”，所以这里表示的是“有朝一日”，故答案为sometime。

47.bring 【解析】通过前一句话“such a dreamer Can be brought back to earth.”中的brought可以知道，这里应该填bring，表示“把…带到”。故答案为bring。

48.1ikely 【解析】前面所说的the person who is down—to—earth与the person whose both feet on the ground大体是一类人，所以这里表达的意思是“很有可能就是一类人”。be likely to do就表达了这种意思。故答案为likely。

49.When 【解析】这里的一句话其实与下一半句“when we are down—to—earth，...”所起到的作用是一样的，同时两者也是并列的，when表达了“当…”，所以这里填when。故答案为when。

50.toward 【解析】作者要表达的意思是“我怎么才能对别人诚实。”英语中表达“对某人…”一般是用介词toward。故答案为toward。
