　　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(將人類摧垮的)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

　　61.C)。定位：由題干中的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.

　　詳解：事實細節題。本題考查地球溫度上升帶來的變化。定位句提到“地球溫度每上升l.8華氏度(1攝 氏度)，那么大西洋中強度可匹敵甚至勝過卡特里娜颶風的颶風數量會增加兩倍乃至七倍”，故C)“更多像卡 特里娜那樣或是更糟糕的颶風”為答案。A)“冰川期到來”原文中未提及，故排除;B)“越來越少的強度颶風” 與原文不符，故排除;D)“大氣層中更多的溫室氣體”原文中未提及，故排除。

　　62.D)。 E—瞳由題干中的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.

　　詳解：瞳事實細節題。本題考查對颶風形成的區域中海水情況的理解。定位句提到“從海洋中蒸發到空氣中的水分越多，那么颶風的威力就越強，然后會直撲陸地”，故D)“蒸發成水蒸氣，使得風暴威力增強”為答案。A)“加熱颶風”原文中未提及，故排除;B)“蒸發后變成燃料”是對“add fuel”的錯誤理解，故排除;C)“直奔陸地”，原文說的是颶風而不是海水，故排除。

　　68.B)。定位：由題干中的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.

　　詳解：事實細節題。本題考查颶風卡特里娜的細節。定位句提到“卡特里娜颶風在抵達新奧爾良州之前 威力大增，其巨大的破壞力致使200余人喪生，并造成了800億美元的經濟損失”，故答案為B)。A)“在移動過程中沒有減弱”，定位句提及在經過佛羅里達州時有所減弱，故排除;C)“颶風給佛羅里達州造成800億美元的損失”與文意不符，故排除;D)“持續24小時”，定位句是指以最強姿態持續24小時，而非僅僅持續24小時，故排除。

　　64.A)。定位：由題干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.

　　詳解：事實細節題。本題考查局域海面溫度的變化對颶風造成的影響。根據定位句，局域海面溫度的變

　　化是颶風變化的主要原因，故答案為A)。B)“溫室氣體排放量增加”和c)“全球變暖”原文并未提及，故均排除：D)“毀滅性的颶風”對原文理解不準確，因為局部海面溫度變化也可能導致颶風減弱，故排除。

　　65.B)。定位：本題是對文章的總體提問，需要對全文有較好的把握并根據各選項逐一定位。

　　詳解：推理判斷題。由倒數第二段最后一句和最后一段的第一句可知，全球變暖是由溫室氣體大量排放引起的，而全球變暖和破壞性風暴頻率變高之間存在聯系，由此可推知，減少溫室氣體排放，或可緩解全球變暖的趨勢，從而減少破壞性風暴的發生頻率，故答案為B)。A)“溫室氣體和破壞性風暴之間不存在聯系”是對文意的曲解，故排除;C)“隨著更多颶風的出現，強度大的颶風所占比例升高”，由最后一段第二句可知，颶風發生頻率與強度大的颶風的比例無明顯關聯，故排除;D)“過去關于颶風的記錄包含所有所需信息”與最后 一段最后一句提到的“沒有全面詳細的數據”相矛盾，故排除。
