3、SemcoAt 21, Ricardo Semler became boss of his father-s business in Brazil, Semco, which sold parts fｏｒships. Semler Juniｏｒworked like a madman, from 7:30 am. , until midnight every day. One afternoon, while touring a factory in New York, he collapsed. The doctｏｒwho treated him said, "There\'s nothing wrong with you. But if you continue like this, you\'ll find a new home in our hospital." Semler got the message. He changed the way he worked. In fact, he changed the way his employees worked too.He let his workers take more responsibility so that they would be the ones worrying when things went wrong. He allowed them to ｓｅｔtheir own salaries, ａｎｄ　he cut all the jobs he thought were unnecessary, like receptionists ａｎｄ　secretaries. This saved money ａｎｄ　brought more equality to the company. "Everyone at Semco, even top managers, meets guests in reception, does the photocopying, sends faxes, types letters ａｎｄ　dials the phone."He completely reorganized the office, instead of walls, they have plants at Semco, so bosses can\'t shut themselves away from everyone else. ａｎｄ　the workers are free to decorate their workspace as they want. As fｏｒuniforms, some people wear suits ａｎｄ　others wear T - shirts.Semler says, "We have a sales manager named Rubin Agater who sits there reading the newspaper hour after hour. He doesn\'t even pretend to be busy. But when a Semco pump an the other side of the world fails ａｎｄ　millions of gallons of oil are about to spill into the sea, Rubin springs into action.____ That\'s when he earns his salary. No one cares if he doesn\'t look busy the rest of the time."Semco has flexible working hours, the employees decide when they need to arrive at work, The employees also evaluate their bosses twice a year. Also, Semco lets its workers use the company\'s machines fｏｒtheir own projects, ａｎｄ　makes them take holidays fｏｒat least thirty days a year.It sounds perfect, but does it work? The answer is in the numbers. In the last six years, Semco\'s revenues have gone from $ 35 million to $ 212 million. The company has grown from eight hundred employees to 3,000, Why?Semler says it\'s because of "peer pressure". Peer pressure makes everyone work hard fｏｒeveryone else. doing his job well, the other workers will not allow the situation to continue. In other words, Ricardo Semler treats his workers like adults ａｎｄ　expects them to act like adults, ａｎｄ　they do. 【单选题】

正确答案:E

答案解析:本题难度也较大，需要认真阅读文章，可用排除法和代入法。本题的前一句谈到，当公司里的泵出现问题，导致大量原油往海里泄露时，新老板就会行动起来，后一句没有接着泵谈，可以推断，本题应继续谈论泵的问题，解释新老板的行动，回来找选项，把E代入原文，符合上下文逻辑，是答案。

4、Computer crimesMore ａｎｄ　more, the operations of our business, governments, ａｎｄ　financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information fｏｒhis own purposes can reap substantial rewards. Even worse, a number of people who have done this ａｎｄ　been caught at it have managed to get away without punishment.It\'s easy fｏｒcomputer crimes to go undetected if no one checks up on what the computer is doing, but even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected but it\'s disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections ｏｒother security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck.Fｏｒexample, a certain keypunch operatｏｒcomplained of having to stay overtime to punch extra cards. Investigation revealed that the extra cards she was being asked to punch were fｏｒdishonest transactions. In another case, dissatisfied employees of the thief tipped off the company that was being robbed unlike other lawbreakers, who must leave the country, commit suicide, ｏｒgo to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations ａｎｄ　perhaps other benefits. All too often, their demands have been met.Why? Because company executives are afraid of the bad publicity that would result if the public found out their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company\'s executives, accountants, ａｎｄ　security staff. ａｎｄ　so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.What may happen to computer criminals once they are caught?【单选题】

A.With bad reputation they can hardly find another job.

B.They will be denied access to confidential records.

C.They may walk away ａｎｄ　easily find another job.

D.They must leave the country ｏｒgo to jail.

正确答案:C

答案解析:答案在文中的倒数第二段中：计算机犯罪分子和其他犯罪分子不同的是，他们不仅不会流亡国外，或者自杀或者进监狱，而且还往往得到原雇主的褒扬和推荐，从而找到另外一份好工作。

5、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US ａｎｄ　one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. ａｎｄ　the last “official” stocks of live virus bred mistrust of the US ａｎｄ　Russia, ____ no obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US ａｎｄ　Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

A.since

B.for

C.because

D.of

正确答案:B

答案解析:整个句子说的是，美、俄“官方”的最后的活病毒储备由于不能带来明显的好处而引起大家对这两个国家的不信任。no?obvious?gain是名词短语。for可跟名词短语，表示原因。because不跟名词短语。since可跟名词短语，但跟表示时间的名词短语。of可跟名词短语，但常表示“所属”关系。故B为正确答案。
