1、Ceasing to Wear TiesIt\'s useless. It\'s dirty. It spreads disease. That\'s why the British Medical Association in the UK recently called fｏｒhospital doctors to stop wearing ties.That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body ａｎｄ　keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France ａｎｄ　eventually evolved into the tie.It\'s an interesting story, but it doesn\'t tell us why men want to put useless pieces of cloth ｏｒsilk around their necks. The answer seems to be about identification(身份证明 ). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools ａｎｄ　gentleman\'s clubs. Each tie was in a particular ｓｅｔof colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain\'s most powerful classes. That made the tie itself a symbol of power ａｎｄ　respect. ａｎｄ　that led it to be adopted by a much larger class-the business class.You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.Is there a future fｏｒties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.Paragraph 6 ________.【单选题】

A.Origin of the tie

B.British ties

C.Uselessness of the tie

D.Old-fashioned ties

E.Role of the tie

F.Signs of a tieless era

正确答案:F

答案解析:第六段的主题句是第二句：The signs are not promising.这里the signs后边省略了of the future of ties。该句说明领带的前景不是很好。比如在后一句中讲到英国首相布莱尔等政治家经常在公共场合不再戴领带，这进一步说明了以后人们可能不再打领带。F选项Signs of a tieless era与其表达相符，故F为正确答案。

2、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems ａｎｄ　work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America ｏｒEurope.Although industrial robots were originally developed as devices fｏｒsimply handling objects, today their commonest uses are fｏｒmore skilled work like welding (焊接), spray-painting ａｎｄ　assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive ａｎｄ　partly because engineers now have more experience with robots ａｎｄ　are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan. The reliability of robots is measured in their MTBF ｏｒmean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day fｏｒtwo years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately ａｎｄ　consistently than humans, who can get tired ａｎｄ　bored.The use of robots increases________.【单选题】

A.too much energy

B.based on American designs

C.they are too costly

D.they are not reliable

E.quality control

F.free of charge

正确答案:E

答案解析:根据“题目顺序与段落顺序基本对应”的出题规律，可定位到最后一段。最后一段共两句话，其中第一句The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control中提到，日本公司宣称引进机器人最大的好处在于可以提高对产品质量的控制。E选项是对该句的同义改写，故E为正确答案。

3、Geology ａｎｄ　Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, ａｎｄ　the idea that geology might be related to health has been recognized fｏｒa number of elements such as iodine, zinc ａｎｄ　selenium. Fｏｒexample, soils with low iodine contents produce crops, ａｎｄ　animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining ｏｒlosing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require fｏｒgrowth. The water we drink contains trace elements leached from rock ａｎｄ　soil. Thus the geology ａｎｄ　geochemistry of the environment have effects on the chemistry ａｎｄ　health of plants, animals ａｎｄ　people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested ｏｒmetal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds ａｎｄ　gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up ａｎｄ　rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer ａｎｄ　are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies ａｎｄ　rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans ａｎｄ　above environmental quality criteria.(6)There is a vital need to understａｎｄ　the potential risks ａｎｄ　long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain ａｎｄ　human body. Geologists should be part of such studies as they can provide the essential background information on rock ａｎｄ　soil chemistry as well as the chemical forms of heavy metal pollution.Some serious diseases is connected with deficiency of ____【单选题】

A.industrially polluted soils

B.rock ａｎｄ　soil chemistry

C.naturally polluted soils

D.the pathways of metals into the food chain

E.the element of iodine

F.the persistence of heavy metals

正确答案:E

答案解析:第1段最后一句“A lack of iodine in the human diet leads to some serious diseases”是选择E的依据。

4、Why People Use Pseudonyms (假名字)?You can\'t choose the name you are given at birth, but in many countries you can change it legally when you reach adulthood. Of course, most people never change their names even if they feel unhappy about them. However some people do take this course of action－particularly artists! What makes an artist want to change their name? Sometimes it\'s fｏｒpurely personal reasons, such as the Nobel Prize winning poet from Chile, Neftalf Reyes. He didn\'t want his father to know he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. At other times the reason may appear strange, take the case of the Portuguese poet Femando Pessoa, who wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, however , people change their names fｏｒsocial, historical, political, ｏｒcultural reasons. Here are some of the most common: reason. The person\'s real name is just too long ａｎｄ　difficult to remember. Let\'s be honest, Madonna Louise Ciccone is not as easy to remember as just plain Madonna. ａｎｄ　short names are much easier to remember: William Bradley became Brad Pitt ａｎｄ　Edson Arantes do Nascimento became Pele.Sometimes names are changed fｏｒmarketing purposes. Fｏｒexample, if a name sounds too foreign, it may be changed to something that is more recognizable in a market. So in the film world, Ramon Estsvez adopted the name Martin Sheen. ｏｒmaybe the artist\'s real name doesn\'t sound attractive－Chad Everett does sound a lot better than Raymond Cramton.Artists sometimes ____ the name of someone they admire. Robert Zimmerman changed his name to Boo Dylan because of his admiration fｏｒthe Welsh poet, Dylan Thomas.Another reason may be practical: in the past, women found it very difficult to get published. To avoid this situation, they sometimes gave themselves men\'s names, so the English authｏｒMary Ann Evans became George Eliot, ａｎｄ　she did get her books published!【单选题】

A.give

B.change

C.choose

D.mention

正确答案:C

答案解析:本题难度不大，可以使用作题技巧，先看选项，得到信息提示，再结合原文，很明显，要用choose，最佳答案是C。

5、African wild dogFinding a babysitter while you go out to work is, fｏｒexample, an inconvenience. Fｏｒthe African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life ａｎｄ　death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food ａｎｄ　stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution ａｎｄ　unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, ａｎｄ　the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults ａｎｄ　pups, only the dominant male ａｎｄ　female breed. The remaining animals help raise the pups, cooperating to hunt prey ａｎｄ　defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions ａｎｄ　hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey ａｎｄ　to defend the kill. There is also one less stomach in which to carry food back to the den, ａｎｄ　one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups ａｎｄ　still spare a babysitter. But with smaller packs, either the hunting ｏｒthe babysitting suffers, ｏｒthe animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals ｏｒfewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poｏｒreproduction ａｎｄ　low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " ａｎｄ　deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.The size of a pack must be big enough fｏｒit to survive.【单选题】
