Our present【3】is with how easily and to what extent this【4】can be modified. The question is no mere academic one. The ease with【5】people can change from working in the day to working at night is a【6】of growing importance in industry where automation【7】round-the-clock working of machines. It normally【8】from five days to one week for a person to adapt to a【9】routine of sleep and wakefulness, sleeping【10】the day and working at night.【11】it is often the case in industry that shifts are changed every week. This【12】that no sooner has he got used to one routine【13】he has to change to another,【14】much of his time is spent neither working nor sleeping very【15】One answer would seem to be【16】periods on each shift, a month, or even three months.【17】, recent research has shown that people on such systems will revert to go back to their【18】habits of sleep and wakefulness during the week-end and that this is quite enough to destroy any【19】to night work built up during the week. The only real solution appears to be to hand over the night shift to those permanent night workers whose【20】may persist through all week-ends and holidays.（分数：40.00）(1).【1】（分数：2.00）A.allegationB.alternationC.allocationD.alternative(2).【2】（分数：2.00）A.overB.ofC.withD.in(3).【3】（分数：2.00）A.thinkB.considerC.regardD.concern(4).【4】（分数：2.00）A.roundB.circleC.periodD.cycle(5).【5】（分数：2.00）A.forB.thatC.WhichD.as(6).【6】（分数：2.00）A.matterB.troubleC.difficulty(7).【7】（分数：2.00）A.reacts toB.calls forC.invitesD.asks(8).【8】（分数：2.00）A.requestsB.demandsC.spendsD.takes(9).【9】（分数：2.00）A.regularB.reversedC.returnedD.former(10).【10】（分数：2.00）A.duringB.afterC.ohD.with(11).【11】（分数：2.00）A.In comparisonB.In a wordC.UnfortunatelyD.Therefore(12).【12】（分数：2.00）A.meanB.meaningC.meantD.means(13).【13】（分数：2.00）A.thanB.thenC.whenD.as(14).【14】（分数：2.00）A.asB.whileC.so thatD.though(15).【15】（分数：2.00）A.happilyB.easilyC.goodD.efficiently(16).【16】（分数：2.00）A.nicerB.longerD.shorter(17).【17】（分数：2.00）A.HoweverB.SimilarlyC.In shortD.So(18).【18】（分数：2.00）A.favouriteB.temporaryC.normalD.new(19).【19】（分数：2.00）A.tendencyB.adaptationC.returnD.change(20).【20】（分数：2.00）A.habitB.preferenceC.sleepD.wakefulness（清华大学2007年试题） Sea rise as a consequence of global warming would immediately threaten that large fraction of the globe living at sea level. Nearly one-third of all human beings live within 36 miles of a coastline. Most of the world's great seaport cities would be【1】: New Orleans, Amsterdam, Shanghai, and Cairo. Some countries — Maldives Islands in the Indian Ocean, islands in the Pacific — would be inundated. Heavily populated coastal areas such as in Bangladesh and Egypt,【2】large populations occupy low-lying areas, would suffer extreme【3】. Warmer oceans would spawn stronger hurricanes and typhoons,【4】in coastal flooding, possibly swamping valuable agricultural ands around the world.【5】water quality may result in【6】flooding which forces salt water into coastal irrigation and drinking water supplies, and irreplaceable, natural【7】could be flooded with ocean water, destroying forever many of the【8】plant and animal species living there. Food supplies and forests would be【9】affected. Changes in rainfall patterns would disrupt agriculture. Warmer temperatures would【10】grain-growing regions polewards. The warming would also increase and change the pest plants, such as weeds and the insects【11】the crops. Human health would also be affected. Warming could【12】tropical climate bringing with it yellow fever, malaria, and other diseases. Heat stress and heat mortality could rise. The harmful【13】of localized urban air pollution would very likely be more serious in warmer【14】There will be some【15】from warming. New sea-lanes will open in the Arctic, longer growing seasons further north will【16】new agricultural lands, and warmer temperature will make some of today's colder regions more【17】. But these benefits will be in individual areas. The natural systems—both plant and animal—will be less a-ble than man to cope and【18】. Any change of temperature, rainfall, and sea level of the magnitude now【19】will be destructive to natural systems and living things and hence to man as well. The list of possible consequences of global warming suggests very clearly that we must do everything we can now to understand its causes and effects and to take all measures possible to prevent and adapt to potential and inevitable disruptions【20】by global warming.（分数：40.00）(1).【1】（分数：2.00）A.ascendedC.erasedD.endangered(2).【2】（分数：2.00）A.whichB.whereC.whenD.what(3).【3】（分数：2.00）A.dislocationB.discontentC.distributionD.distinction(4).【4】（分数：2.00）A.rebukingB.ramblingC.resultingD.rallying(5).【5】（分数：2.00）A.IncreasedB.ReducedC.ExpandedD.Saddened(6).【6】（分数：2.00）A.inlandB.coastalC.urbanD.suburban(7).【7】（分数：2.00）A.dry-landB.mountainC.wetlandsD.forest(8).【8】（分数：2.00）A.uniqueB.preciousC.interestingD.exciting(9).【9】（分数：2.00）A.geologicallyB.adverselyC.secretivelyD.serially(10).【10】（分数：2.00）A.shiftB.generateC.greaseD.fuse(11).【11】（分数：2.00）A.hikingB.huggingC.attackingD.activating(12).【12】（分数：2.00）A.endangerB.accommodateC.adhereD.enlarge(13).【13】（分数：2.00）A.profitsB.valuesC.effectsD.interests(14).【14】（分数：2.00）A.conditionsB.accommodationC.surroundingsD.evolution(15).【15】（分数：2.00）A.adjustmentsB.benefitsC.adoptionsD.profits(16).【16】（分数：2.00）A.alternateB.abuseC.advocateD.create(17).【17】（分数：2.00）A.accidentalB.habitableC.anniversaryD.ambient(18).【18】（分数：2.00）A.adaptB.alleviateC.agitateD.assert(19).【19】（分数：2.00）A.ascertainedB.conformedC.consoledD.anticipated(20).【20】（分数：2.00）A.tutoredB.relayedC.triggeredD.reflected。
