Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area--and they can be devastating．In 1906，for example，a major quake destroyed about 28,000 buildings and killed hundreds，perhaps thousands of people．Residents now wonder when the next“Big One”will strike．It's bound to happen someday．At least seven active fault(断层)lines run through the San Francisco area． Faults are places where pieces of Earth's crust(地壳)slide past each other．When 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 quake is that the San Andreas fault split apart faster than scientists had assumed at the time．During small earthquakes，faults rupture(断裂)at about 2.7 kilometers per second．During bigger quakes，however．ruptures can happen at rates faster than 3.5 kilometers per second． At such high speeds，massive amounts of pressure build up，generating underground waves that can cause more damage than the quake itself．Lucky for San Francisco，these pressure pulses(脉冲)traveled away from the city during the 1906 event．As bad as the damage was，it could have been far worse． Looking ahead．scientists are trying to predict when the next major quake will occur．Records show that earthquakes were common before 1906．Since then，the area has been relatively quiet．Patterns 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 quakes．Still，more than 84 percent of the city's buildings are old and weak．Analyses suggest that another massive earthquake would cause extensive damage． People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while．According to the new research，however．it's not a matter of“if”the Big One will hit．It's just a matter of when．

第一篇
Walking to Exercise the Brain
Do you think sitting and studying all the time will improve students'grades? Think again．Getting some exercise may help，too． New research with older people suggests that taking regular walks helps them pay attention better than if they didn't exercise． Previous research had shown that mice learn，remember，and pay attention better after a few weeks of working out on a running wheel．Mice that exercise have greater blood flow to the brain than those who don't．Their brain cells also make more connections． Neuroscientists(神经科学家)from the University of Illinois at Urbana-Champaign wanted to find out if the same thing is true for people．First，they measured the physical fitness of 41 adults，ages 58 to 77，after each person walked 1 mile．Then，participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing． Adults who were physically fit were faster at the arrow task，and their answers were just as accurate as their less-fit peers，the researchers found．The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions． In a second study，15 elderly people who completed a 6-month aerobic-training(有氧运动)course were faster at attention tasks compared with 14 seniors who just did stretching and toning(韵律操)exercises for the same amount of time． So，even going for a walk every 2 or 3 days for just 10 to 45 minutes can help．That should be good news for the elderly． The effects of exercising on the brains of younger people haven't been studied yet．Still，it can't hurt to take occasional breaks and go for a walk or run around with friends．Whatever you do，though，don't try to read and walk at the same time．You could end up hurting yourself!
5. It is suggested in the last paragraph that people should
A.run around once a week．

第二篇
Night of the Living Ants
When an ant dies，other ants move the dead insect out of the nest．This behavior is interesting to scientists，who wonder how ants know for sure-and so soon-that another ant is dead． Dong-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 dead-take me away．” But there's a twist to Choe's discovery．Choe says that the living ants-not just the dead ones -have this death chemical．In other words，while an ant crawls around，perhaps in a picnic or home，it's telling other ants that it's dead． What keeps ants from hauling away the living 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 up．That means ants know that unmoving ants can still be alive． Choe 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 the treated pupae away． When the scientists used the“Wait-I'm not dead yet”chemical，other ants left the treated pupae alone． Choe believes this behavior shows that the“not dead yet”chemical overrides(优胜于)the“dead”chemical when picked up by adult ants．And that when an ant dies，the“not dead yet”chemical fades away． Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest．
1. The phrase“this death chemical”in paragraph 3 refers to
On a September day in 1991，two Germans were climbing the mountains between Austria and Italy． High 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 year．The mountain ice had melted more than usual and so the body had come to the surface． It was lying face downward．The skeleton(骨架)was in perfect condition，except for a wound in the head．There was still skin on the bones and the remains of some clothes．The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots．Nearby was a pair of gloves made of tree bark(树皮)and a holder for arrows． Who was this man?How and when had he died?Everybody had a different answer to these questions．Some people thought that it was from this century，perhaps the body of a soldier who died in World War I，since several soldiers had already been found in the area．A Swiss woman believed it might be her father，who had died in those mountains twenty years before and whose body had never been found．The scientists who rushed to look at the body thought it was probably much older，maybe even a thousand years old． With modern dating techniques，the scientists soon learned that the Iceman was about 5,300 years old．Born in about 3300 B．C．，he lived during the Bronze Age in Europe．At first scientists thought he was probably a hunter who had died from an accident in the high mountains．More recent evidence，how ever，tells a different story．A new kind of X-ray shows an arrowhead still stuck in his shoulder．It left only a tiny hole in his skin，but it caused internal damage and bleeding．He almost certainly died from this wound，and not from the wound on the back of his head．This means that he was probably in sortie kind of a battle．It may have been part of a larger war，or he may have been fighting bandits．He may even have been a bandit himself． By studying his clothes and tools，scientists have already learned a great deal from the Iceman about the times he lived in．We may never know the full story of how he died，but he has given us important clues to the history of those distant times．
1. The body of the Iceman was found in the mountains mainly because
At 21，Ricardo Semler became boss of his father's business in Brazil，Semco，which sold parts for ships．Semler Junior worked like a madman，from 7:30 a.m.，until midnight every day．One afternoon， while touring a factory in New York，he collapsed．The doctor who treated him said，“There's nothing wrong with you．But if you continue like this．you'll find a new home in our hospital．”Semler got the message．He changed the way he worked．In fact，he changed the way his employees worked too． He let his workers take more responsibility so that they would be the ones worrying when things went wrong．He allowed them to set their own salaries，and he cut all the jobs he thought were unnecessary，like receptionists and secretaries． 1 “Everyone at Semco．even top managers，meets guests in reception，does the photocopying，sends faxes，types letters and dials the phone．” He completely reorganized the office：instead of walls，they have plants at Semco，so bosses can't shut themselves away from everyone else． 2 As for uniforms，some people wear suits and others wear T-shirts． Semler says，“We have a sales manager named Rubin Agater who sits there reading the newspaper hour after hour．He doesn't even pretend to be busy．But when a Semco pump on the other side of the world fails and millions of gallons of oil are about to spill into the sea，Rubin springs into action． 3 That's when he earns his salary．No one cares if he doesn't look busy the rest of the time．” Semco has flexible working hours；the employees decide when they need to arrive at work．The employees also evaluate their bosses twice a year． 4 It sounds perfect，but does it work?The answer is in the numbers：in the last six years，Semco's revenues have gone from $35 million to $212 million．The company has grown from eight hundred employees to 3,000．Why? Semler says it's because of“peer pressure”．Peer pressure makes everyone work hard for everyone else． 5 In other words，Ricardo Semler treats his workers like adults and expects them to act like adults．And they do． A．Also，Semco lets its workers use the company's machines for their own projects，and makes them take holidays for at least thirty days a year． B．Most managers spend their time making it difficult for workers to work． C．This saved money and brought more equality to the company． D．And the workers are free to decorate their workspace as they want． E．He knows everything there is to know about our pumps and how to fix them． F．If someone isn't doing his job well，the other workers will not allow the situation to continue．
One useful anti-cancer drug can effectively erase the whorls(萝状指纹)and other characteristic marks that give people their distinctive fingerprints．Losing them could become troublesome．A case 1 online in a letter by Annals of Oncology indicates how big a 2 losing finger prints is． Eng-Huat Tan，a Singapore-based medical doctor describes a 62-year-old man who has used capecitabine(卡培他滨)to 3 his nasopharyngeal cancer(鼻咽症)．After three years on the 4 ，the patient decided to visit his U．S．relatives last December．But he was stopped by U．S． customs officials 5 4 hours after entering the country when those officials couldn't get finger prints from the man．There were no 6 swirly(旋涡状的)marks appearing from his index fin ger． U．S．customs has been fingerprinting incoming foreign visitors for years，Tan says．Unfortunately， for the Singaporean traveler，one potential 7 effect of his drug treatment is a smoothing of the tissue on the finger pads． 8 ，no fingerprints． “It is uncertain when fingerprint 9 will begin to take place in patients who are taking capecitabine，”Tan points out．So he 10 any physicians who prescribe the drug to provide their patients with a doctor's 11 pointing Out that their medicine may cause fingerprints to disappear． Eventually，the Singaporean traveler made it into the United States．But he's also now got the explanatory doctor's note-and won't leave home 12 it． By the way，maybe the Food and Drug Administration， 13 approved use of the drug 11 years ago，should consider updating its list of side effects 14 with this medicine．The current list does note that patients may experience vomiting(呕吐)，stomach pain and some other side effects． But no where 15 it mention the potential for loss of fingerprints．
