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 next"Big One"will strikeIt's bound to happen somedayAt least seven active fault(断层)lines run through the San Francisco areaFaults are places where pieces of Earth's crust(地壳)slide past each otherWhen these pieces slip，the ground shakesTo 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 happensOne 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 secondAt 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 worseLooking 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 percentNew buildings in San Francisco are quite safe in case of future quakesStill，more than 84 per-cent of the city's buildings are old and weakAnalyses suggest that another massive earthquake would cause extensive damagePeople who live there tend to feel safe because San Francisco has remained pretty quiet for a whileAccording to the new reseaych，however，it's not a matter of"if the Big One will hit"It's just a matter of when16The San Francisco area is located

reservoirs deep beneath the earth's 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 cleanlyThe United States consumes about one-third of the world's natural gas output，making it the lar-gest gas consuming region in the worldThe USDepartment of Energy's 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 earth's 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 gasBNatural gas reserves

BrainDo you think sitting and studying all the time will improve your grades?Think againGetting some exercise may help，tooNew research with older people suggests that taking regular walks helps them pay attention better than if they didn't exercisePrevious research had shown that mice learn，remember，and pay attention better after a few weeks of working out on a running wheelMice that exercise have greater blood flow to the brain than those who don'tTheir brain cells also make more connectionsNeuroscientists from the University at Urbana-Champaign wanted to find out if the same thing is true for peopleFirst，they measured the physical fitness of 41 adults，ages 58 to 77，after each per-son walked 1 mileThen，participants looked at arrows on a computer sczeen and had to use com-puter keys to show which way one particular arrow was pointingAdults who were physically fit were faster at the arrow task，and their answers were just as ac- curate as their less-fit peers,the researchers foundThe fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisionsIn a second study，15 elderly people who completed a 6-month aerobic-training course were fas-ter at attention tasks compared with 14 seniors who just did stretching and toning exercises for the same amount of timeSo，even going for a walk every 2 or 3 days forjust 10 to 45 minutes can helpThat should be good news for your grandparentsThe effects of exercising on the brains of younger people haven't been studied yetStill，it can't hurt to take occasional study breaks and go for a walk or run around with your friendsYou might even do better in schoolWhatever you do，though，don't try to read and walk at the same timeYou could end up hurting yourseff!31Walking regularly helps elderly people_Alose weightBbecome happierCconcentrate betterDlook younger32After taking exercise for a few weeks，the mice were found to have_Ahigher blood pressureBfaster heartbeatCmore blood flow to the brainDbetter appearance33The first study on 41 elderly people found_Athe less-fit participants did arrow tasks fasterBthe fitter participants did arrow tasks fasterCthe less-fit participants gave more accurate answersDthe fitter participants gave more accurate answers34It can be good for health when one takes a walk every 2 or 3 days for at least_A3 minutesB45 minutesC30 minutesD10 minutes35It is suggested in the last paragraph that people should_Arun around once a weekBnot read and walk at the same timeCgo for a walk every dayDnot hurt their friends while exercising第二篇Night of the Living AntsWhen an ant dies，other ants move the dead insect out of the nestThis behavior is interesting to scientists，who wonder how ants know for sure and so soon that another ant is deadDong-Hwan Choe，a scientist at the University of California found that Argentine ants have a chemical on the outside of their bodies that signals to other ants"I'm deadtake me away"But there's a twist to Choe's discoveryThese ants ave a little bit like zombies(僵尸)Choe says that the living ants，not just the dead ones，have this death chemicalsIn other wordsWhile an ant crawls around，perhaps in a picnic or home，it's telling other ants that it's deadWhat keeps ants from hauling away the liring dead?Choe found that Argentine ants have two additional chemicals on their bodies，and these tell nearby ants something like，"Wait-I'm not dead yet，"So Choe's research turned up two sets of chemical signals in ants：one says，"I'm dead"the other set says，"I'm not dead yet"Other scientists have tried to figure out how ants know when another ant is dead If an ant is knocked unconscious，other ants leave it alone until it wakes upThat means ants know that unmoving ants can still be aliveChoe suspects that when an Argentine ant dies，the chemical that says"Wait-I'm not dead yet" quickly goes away.Once that chemical is gone，only the one that says"I'm dead"is left"It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地)，not because its body releases new unique chemicals after death，"said Choe When other ants detect the"dead"chemical without the"not dead yet"chemical，they haul away the body This was choe's hypothesis(假设)To test his hypothesis，Choe and his team put different chemicals on Argentine ant pupae(蛹). When the scientists used the"I'm dead"chemical，other ants quickly hauled tbe treated pupae away. When the scientists used the"Wait-I'm not dead yet"chemicals，other ants left the treated pupae alone.Choe believes this behavior shows that the"not dead yet"chemicals override(优先于) the"dead"chemical when picked up by adult ants And that when an ant dies，the"not dead yet"chemicals fade awayOther nearby ants then detect the remaining"dead"chemical and remove the body from the nest36What is meant by"death chemical"mentioned in paragraph 3?AA chemical that contains poisonBA chemical that causes deathCA chemical that announces deathDA chemical that prevents death37Which of the following statements is NOT true of ants?AAnts know very soon that another ant is deadBWhen an ant is dead，others move its body out of the nestCIf an ant is unconscious，it is moved out of the nestDLiving ants have the"I'm dead"chemical on their bodies38According to Choe's hypothesis，_.Aan ant still smells like a living when it diesBthe"I am dead"chemical leaves the ant's body when it diesCthe"I am not dead yet"chemical is left when an ant diesDthe"I am not dead yet"chemical leaves the ant's body when it dies39According to paragraph 7，what is the result of the test on Choe's hyothesis?AIt shows that his hypothesis is wrongBIt proves that his hypothesis is convincingCIt suggests that his hypothesis needs revisingDNot enough evidence has been found to support his hypothesis40The passage"Night of the Living Ants"tells us about_.Ahow an ant is moved out of the nest at nighBwhat an ant does at nightChow an ant finds its way in darknessDwhat happens when an ant dies第三篇The IcemanOn 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 been an especially warm yearThe mountain ice had melted more than just usual and so the body had come to the surfaceIt was lying face downwardThe skeleton(骨架)was in perfect condition，except for a wound in the headThere was s
