Everyone who lives in San Francisco knows that earthquakes are common in the bay area and they can be devastatingIn 1906，for example，a major quake destroyed about 28，000 buildings and killed hundreds，perhaps thousands of peopleResidents now wonder when the nextBig Onewill strikeIts bound to happen somedayAt least seven active fault(断层)lines run through the San Francisco areaFaults are places where pieces of Earths crust(地壳)slide past each otherWhen these pieces slip，the ground shakes To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists had assumed at the timeDuring small earthquakes，faults rupture(断裂)at about 2.7 kilometers per secondDuring bigger quakes，however，ruptures can happen at rates faster than 3.5 kilometers per second At such high speedsmassive amounts of pressure build up，generating underground waves that can cause more damage than the quake itselfLucky for San Francisco，these pressure pulses(脉冲)travel away from the city during the 1906 eventAs bad as the damage was，it could have been far worse Looking ahead，scientists are trying to predict when the next major quake will occurRecords show that earthquakes were common before 1906Since then，the earthquake has been relatively quietPatterns in the data，however，suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent New buildings in San Francisco are quite safe in case of future quakesStill，more than 84 per-cent of the citys buildings are old and weakAnalyses suggest that another massive earthquake would cause extensive damage People who live there tend to feel safe because San Francisco has remained pretty quiet for a whileAccording to the new reseaych，however，its not a matter ofif the Big One will hitIts just a matter of when 16The San Francisco area is located above several active fault lines ARight BWrong CNot mentioned 17The 1906 earthquake in San Francisco is the most severe one in American history ARight BWrong CNot mentioned 18The highest speed of fault ruptures in the 1906 quake was more than 3.5 kilometers per second. ARight BWrong CNot mentioned 19Earthquakes rarely happened before 1906 ARight BWrong CNot mentioned 20San Francisco is fully prepared for another big earthquake ARight BWrong CNot mentioned 21Scientist will be able to predict the exact time of an earthquake soon ARight BWrong CNot mentioned 22A major earthquake striking San Francisco someday is inevitable ARight BWrong CNot mentioned 第3部分：概括大意与完成句子(第2330题，每题1分，共8分) 下面的短文后有2项测试任务：(1)第23-26题要求从所给的6个选项中为第25段每段选择1个最佳标题；(2)第2730题要求从所给的6个选项中为每个句子确定1个最佳选项。 Natural Gas Natural gas is produced from reservoirs deep beneath the earths surfaceIt is a fossil fuel，meaning that it is derived from organic material buried in the earth millions of years ago.The main component of natural gas is methane(甲烷). The popularity and use of clean natural gas has increased dramatically over the past 50 years as Dipeline infrastructure(基础设施)has been installed to deliver it conveniently and economically to millions of residential，commercial and industrial customers worldwideToday，natural gas service is available in all 50 states，and is the leading energy choice for fueling American homes and indus-triesMore than 65 million American homes use natural gasIn fact，natural gas is the most eco-nomical source for home energy needs，costing one-third as much as electricity. In addition to heat-ing homes，much of the gas used in the United States is used as a raw material to manufacture a wide variety of products，from paint，to fibers for clothing，to plastics for healthcare，computing and fur-nishings Natural gas is also used in a significant number of new electricity-generating power plants. Natural gas is one of the safest and cleanest fuels available It emits less pollution than other fossil fuelsdioxide(二氧化碳)and water vapor-the same substances emitted when humans ex-haleCompared with some other fossil fuels，natural gas emits the least amount of carbon dioxide in-to the air when combusted(燃烧)-making natural gas the cleanest burning fossil fuel of allThe industry also is subject to substantial federal regulation in the areas of production and distribution，which help ensure it is provided to consumers safely and cleanly The United States consumes about one-third of the worlds natural gas output，making it the lar-gest gas consuming region in the worldThe USDepartment of Energys Energy Information Ad-ministration forecasts that natural gas demand will grow by more than 50 percent by 2025. There are huge reserves of natural gas beneath the earths surfaceThe largest reserves of natu-ral gas can be found in Russia，West and North Africa and the Middle EastLNG(液化天然气)has been produced domestically and imported in the United States for more than four decades.To-day，the leading importers of LNG are Japan，Korea，France and Spain. 23Paragraph 2_ 24Paragraph 3_ 25Paragraph 4_ 26Paragraph 5_ APopularity and use of natural gas BNatural gas reserves and supply CNatural gas prices DClean fuel of choice EDisadvantages of natural gas FNatural gas consumption 27Natural gas is stored deep_. 28Natural gas is recognized as the most economical energy source _. 29When manufacturing many products，people commonly use natural gas _. 30It is estimated that by 2050 that natural gas demand in the United States will increase_.

When the scientists used theIm deadchemical，other ants quickly hauled tbe treated pupae away. When the scientists used theWait-Im not dead yetchemicals，other ants left the treated pupae alone.Choe believes this behavior shows that thenot dead yetchemicals override(优先于) thedeadchemical when picked up by adult ants And that when an ant dies，thenot dead yetchemicals fade awayOther nearby ants then detect the remainingdeadchemical and remove the body from the nest 36What is meant bydeath chemicalmentioned in paragraph 3? AA chemical that contains poison BA chemical that causes death CA chemical that announces death DA chemical that prevents death 37Which of the following statements is NOT true of ants? AAnts know very soon that another ant is dead BWhen an ant is dead，others move its body out of the nest CIf an ant is unconscious，it is moved out of the nest DLiving ants have theIm deadchemical on their bodies 38According to Choes hypothesis，_. Aan ant still smells like a living when it dies BtheI am deadchemical leaves the ants body when it dies CtheI am not dead yetchemical is left when an ant dies DtheI am not dead yetchemical leaves the ants body when it dies 39According to paragraph 7，what is the result of the test on Choes hyothesis? AIt shows that his hypothesis is wrong BIt proves that his hypothesis is convincing CIt suggests that his hypothesis needs revising DNot enough evidence has been found to support his hypothesis 40The passageNight of the Living Antstells us about_. Ahow an ant is moved out of the nest at nigh Bwhat an ant does at night Chow an ant finds its way in darkness Dwhat happens when an ant dies 第三篇 The Iceman On a September day in 1991，two Germans were climbing the mountain between Austria and ItalyHigh up on a mountain pass，they found the body of a man lying on the ice. At that height (10,499 feet or 3，200 meters)，the ice is usually permanent，but 1991 had be
