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

　　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 themaximum Category 5 designation for a full 24 hours in late August 2005. 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 Katrina-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 planet into the 21st century could increase the frequency of the worstkinds of storms by 700 percent, threatening coastlines along the Atlantic Ocean with muitipleCategory 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 Centerfor Ice and Climate at the University of Copenhagen. The large impact of small sea-surfacetemperature 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 researchers reported that the Earth's 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 greenhouse gaseslike carbon dioxide and methane.

　　Past hurricanes have supported the study's finding that global temperature rise is linkedto more destructive storms. According to the National Center for Atmospheric Research, whilethe frequency of storms doesn't appear to have increased, the percentage of strong ones hasrisen sharply over the past few decades. The trend may be similar further back in time, butcomprehensive hurricane data doesn't exist.

　　61. According to the team of international researchers based at Beijing Normal University,the rise of the Earth's temperature is likely to cause

　　A.the coming of ice age

　　C.more Katrina-like or worse hurricanes

　　B.less intense hurricanes

　　D.more greenhouse gases in the atmosphere

　　62. The ocean water in the region where the storm forms

　　A.is heating the hurricanes

　　B.evaporates and becomes 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 did not lose its strength as it moved.

　　B.It claimed over 200 people's 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 gas 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

　　D.past records on hurricanes included everything needed

　　六级考试仔细阅读精选题答案

　　61.C)。定位：由题干中的Beijing Normal University和the Earth’s temperature定位到第三段....for every 1.8T(1℃)rise of the Earth’s temperature，the number of hurricanes in the Atlantic that are as strong or stronger than Hurricane Katrina will increase twofold to sevenfold.

　　详解：事实细节题。本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。A)“冰川期到来”原文中未提及，故排除;B)“越来越少的强度飓风” 与原文不符，故排除;D)“大气层中更多的温室气体”原文中未提及，故排除。

　　62.D)。 E—瞳由题干中的ocean water定位到第四段第二句：More water vapor in the air from evaporating ocean water adds fuel to hurricanes--also called cyclones and typhoons in different parts of the world— that build strength and head toward land.

　　详解：瞳事实细节题。本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。A)“加热飓风”原文中未提及，故排除;B)“蒸发后变成燃料”是对“add fuel”的错误理解，故排除;C)“直奔陆地”，原文说的是飓风而不是海水，故排除。

　　68.B)。定位：由题干中的Hurricane Katrina定位到第五段：Hurricane Katrina is widely considered the measure

　　for a destructive storm.…king more than 200 people and causing $80 billion in damage.

　　详解：事实细节题。本题考查飓风卡特里娜的细节。定位句提到“卡特里娜飓风在抵达新奥尔良州之前 威力大增，其巨大的破坏力致使200余人丧生，并造成了800亿美元的经济损失”，故答案为B)。A)“在移动过程中没有减弱”，定位句提及在经过佛罗里达州时有所减弱，故排除;C)“飓风给佛罗里达州造成800亿美元的损失”与文意不符，故排除;D)“持续24小时”，定位句是指以最强姿态持续24小时，而非仅仅持续24小时，故排除。

　　64.A)。定位：由题干regional sea surface temperature changes定位到第七段第二句：……changes in regional sea surface temperatures is the primary cause of hunicane variability.

　　详解：事实细节题。本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)。B)“温室气体排放量增加”和c)“全球变暖”原文并未提及，故均排除：D)“毁灭性的飓风”对原文理解不准确，因为局部海面温度变化也可能导致飓风减弱，故排除。

　　65.B)。定位：本题是对文章的总体提问，需要对全文有较好的把握并根据各选项逐一定位。

　　详解：推理判断题。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)。A)“温室气体和破坏性风暴之间不存在联系”是对文意的曲解，故排除;C)“随着更多飓风的出现，强度大的飓风所占比例升高”，由最后一段第二句可知，飓风发生频率与强度大的飓风的比例无明显关联，故排除;D)“过去关于飓风的记录包含所有所需信息”与最后 一段最后一句提到的“没有全面详细的数据”相矛盾，故排除。
