1、大学英语六级阅读练习题及答案xx年12月大学英语六级阅读练习题及答案 Small increases in temperature found to add power to storms in the Atlantic. Hurricanes that form in the Atlantic Ocean are expected to gain considerable strength asthe global temperature continues to rise, a new study has found. Using modeling data focused on the

2、conditions in which hurricanes form, a group ofinternational researchers based at Beijing Normal University found that for every 1.8F ( 1 )rise of the Earths temperature, the number of hurricanes in the Atlantic that are as strong orstronger than Hurricane Katrina will increase twofold to sevenfold.

3、 Hurricane strength is directly related to the heat of the water where the storm forms. Morewater vapor in the air from evaporating ocean water adds fuel to hurricanes that build strengthand head toward land. Hurricane Katrina is widely considered the measure for a destructive storm, holding themaxi

4、mum Category 5 designation for a full 24 hours in late August xx. It lost strength as itpassed over the Florida peninsula, but gained destructive power fight before colliding withNew Orleans, killing more than 200 people and causing $ 80 billion in damage. The study points to a gradual increase of K

5、atrina-like events. The warming experiencedover the 20th century doubled the number of such debilitating(将人类摧垮的)storms. But theongoing warming of the pla into the 21st century could increase the frequency of theworst kinds of storms by 700 percent, threatening coastlines along the Atlantic Ocean wit

6、hmuitiple Category 5 storms every year. Our results support the idea that changes in regional sea surface temperatures is theprimary cause of hurricane variability, said Aslak Girnstead, a researcher with the Center forIce and Climate at the University of Copenhagen. The large impact of small sea-su

7、rfacetemperature increases was more than Girustead and his colleagues had anticipated. Theentire study was published in the Proceedings of the National Academy of Sciences. Global temperatures have steadily increased, making the past decade the warmest onrecord. Earlier this year, climate researcher

8、s reported that the Earths temperatures have risenfaster in the last century than at any point since the last ice age, 11,300 years ago. Theprimary cause, a couseusus of scientists has said, is the rising emissions of greenhousegases like carbon dioxide and methane. Past hurricanes have supported th

9、e studys finding that global temperature rise is linkedto more destructive storms. Aording to the National Center for Atmospheric Research, whilethe frequency of storms doesnt appear to have increased, the percentage of strong ones hasrisen sharply over the past few decades. The trend may be similar

10、 further back in time, butprehensive hurricane data doesnt exist. 61. Aording to the team of international researchers based at Beijing Normal University,the rise of the Earths temperature is likely to cause A.the ing of ice age C.more Katrina-like or worse hurricanes B.less intense hurricanes D.mor

11、e greenhouse gases in the atmosphere 62. The ocean water in the region where the storm forms A.is heating the hurricanes B.evaporates and bees fuel C.heads toward land D.turns into water vapor that makes hurricanes stronger 63. Which of the following statement is TRUE about Hurricane Katrina? A.It d

12、id not lose its strength as it moved. B.It claimed over 200 peoples lives. C.It caused 80 billion dollars loss for Florida peninsula. D.It lasted for full 24 hours. 64. What result can regional sea surface temperature changes produce? A.Hurricane changes. C.Global warming. B.Increasing greenhouse ga

13、s emissions. D.Destructive hurricanes. 65. It can be inferred from the passage that A.there is no link between greenhouse gas emissions and destructive storms B.reduction of greenhouse gas emissions may reduce destructive storms C.the higher percentage of strong ones rose as more hurricanes appeared

14、 D.past records on hurricanes included everything needed 参考答案 61.C)。此题考查地球温度上升带来的变化。定位句提到“地球温度每上升l.8华氏度(1摄 氏度)，那么大西洋中强度可匹敌甚至胜过卡特里娜飓风的飓风数量会增加两倍乃至七倍”，故C)“更多像卡 特里娜那样或是更糟糕的飓风”为答案。 62.D)。此题考查对飓风形成的区域中海水情况的理解。定位句提到“从海洋中蒸发到空气中的水分越多，那么飓风的威力就越强，然后会直扑陆地”，故D)“蒸发成水蒸气，使得风暴威力增强”为答案。 68.B)。此题考查飓风卡特里娜的细节。定位句提到“卡特里娜

15、飓风在抵达新奥尔良州之前 威力大增，其宏大的破坏力致使200余人丧生，并造成了800亿美元的经济损失”，故答案为B)。 64.A)。此题考查局域海面温度的变化对飓风造成的影响。根据定位句，局域海面温度的变 化是飓风变化的主要原因，故答案为A)。 65.B)。由倒数第二段最后一句和最后一段的第一句可知，全球变暖是由温室气体大量排放引起的，而全球变暖和破坏性风暴频率变高之间存在联系，由此可推知，减少温室气体排放，或可缓解全球变暖的趋势，从而减少破坏性风暴的发生频率，故答案为B)。 Theyre still kids, and although theres a lot thatthe expert

16、s dont yet know about them, one thingthey do agree on is that what kids use and expectfrom their world has changed rapidly. And its allbecause of technology. To the psychologists, sociologists, and generational and media experts who study them,their digital gear sets this new group apart, even from

17、their tech-savvy (懂技术的) Millennialelders. They want to be constantly connected and available in a way even their older siblingsdont quite get. These differences may appear slight, but they signal an all-enpassingsensibility that some say marks the dawning of a new generation. The contrast between Mi

19、hose born since the early 1990s is sodifferent from the Millennials he wrote about in his xx book, Me, MySpace and I: Parenting theNet Generation, that they warrant the distinction of a new generation, which he has dubbedthe ingeneration. The technology is the easiest way to see it, but its also a m

20、ind-set, and the mind-set goeswith the little i, which Im talking to stand for individualized, Rosen says. Everything isdefined and individualized to me. My music choices are defined to me. What I watch onTV any instant is defined to me. He says the iGeneration includes todays teens and middle-schoo

21、l ers, but its too soon to tell about elementary-school ages and younger. Rosen says the iGeneration believes anything is possible. If they can think of it, somebodyprobably has or will invent it, he says. They expect innovation. They have high expectations that whatever they want or can use will be

22、 able to be tailoredto their own needs and wishes and desires. Rosen says portability is key. They are inseparable from their wireless devices, which allowthem to text as well as talk, so they can be constantly connected-even in class, where cellphones are supposedly banned. Many researchers are try
