“Liquefaction” Key to Much of Japanese Earthquake DamageThe massive subduction zone earthquake in Japan caused a significant level of soil“liquefaction” that has surprised researchers with its1severity,a new analysis shows.“We've seen localized examples of soil liquefaction as extreme as this before,but the distance and2of damage in Japan were unusually severe,”said Scott Ashford,a professor of geotechnical engineering at Oregon State University.“Entire structures were tilted and sinking into the sediments,”Ashford said.“The shifts in soil destroyed water,drain and gas pipelines,crippling the utilities and infrastructure these communities need to3. We saw some places that sank as much as four feet.”Some degree of soil liquefaction is common in almost any major earthquake. It's a phenomenon in which soils soaked with water,particularly recent sediments or sand,can lose much of their4and flow during an earthquake. This can allow structures to shift or sink or5.But most earthquakes are much6than the recent event in Japan,Ashford said. The length of the Japanese earthquake,as much as five minutes,may force researchers to recon-sider the extent of liquefaction damage possibly occurring in situations such as this.“With such a long-lasting earthquake,we saw7structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes,”he said.“And it was clear that younger sediments,and especially areas built on8filled ground,are much more vulnerable.”The data provided by analyzing the Japanese earthquake,researchers said,should make it possible to improve the understanding of this soil9and better prepare for it in the future.Ashford said it was critical for the team to collect the information quickly,10damage was removed in the recovery efforts.“There's no doubt that we'll learn things from what happened in Japan that will help us to reduce risks in other similar11,”Ashford said.“Future construction in some places may make more use of techniques known to reduce liquefaction,such as better compaction to make soils dense,or use of reinforcing stone columns.”Ashford pointed out that northern California have younger soils vulnerable to liquefac-tion一on the coast,near river deposits or in areas with filled ground. The“young”sedi-ments,in geologic terms,may be those12within the past 10,000 years or more. In Ore-gon,for instance,that describes much of downtown Portland,the Portland International Airport and other cities.Anything13a river and old flood plains is a suspect,and the Oregon Department of Transportation has already concluded that 1,100 bridges in the state are at risk from an earthquake.Fewer than 15 percent of them have been reinforced to14collapse. Japan has suffered tremendous losses in the March 11 earthquake,but Japanese construction15 helped prevent many buildings from collapse一even as they tilted and sank into the ground.14._________A: prevent B: accelerate C: predict D: detect

第一篇Can Buildings Be Designed to Resist Terrorist Attack?In the aftermath of the terrorist attack on the World Trade Center,structural engineers are trying hard to solve a question that a month ago would have been completely unthinkable:Can buildings be designed to withstand catastrophic blasts inflicted by terrorists?Ten days after the terrorist attacks on the twin towers,structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research(MCEER)headquartered at UB traveled to ground zero as part of a project funded by the National Science Foundation.Visiting the site as part of an MCEER reconnaissance visit,they spent two days beginning the task of formulating ideas about how to design such structures and to search for clues on how to do so in buildings that were damaged but still are standing."Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center,those buildings that are still standing,but that sustained damage,"said M.Bruneau,Ph.D."Our im-mediate hope is that we can develop a better understanding as to why those buildings remain standing,while our long-term goal is to see whether earthquake engineering technologies can be married to existing technolo-- gies to achieve enhanced performance of buildings in the event of terrorist attacks,"he added.Photographs taken by the investigators demonstrate in startling detail the monumental damage inflicted on the World Trade Center towers and buildings in the vicinity.One building a block away from the towers remains standing,but was badly damaged."This building is many meters away from the World Trade Center and yet we see a column there that used to be part of that building,"explained A.Whittaker,Ph.D."The column became a missile that shot across the road,through the window and through the floor."The visit to the area also revealed some surprises,according to the engineers.For example,the floor framing system in one of the adjacent buildings was quite rugged,allowing floors that were pierced by tons ol falling debris to remain intact. " Highly redundant ductile（有延展性的）framing systems may provide a sim-pie,but robust strategy for blast resistance,"he added.Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails."We also need a better understanding of the mechanism of collapse,"said A.Whittaker."We need to find out what causes a building to collapse and how you can predict it."A.Reinhorn,Ph.D.noted that"Earthquake shaking has led to the collapse of many buildings in the past.It induces dynamic response and extremely high stresses and deformations in structural components.So- lutions developed for earthquake-resistant design may be directly applicable to blast engineering and terrorist-resistant design.Part of our mission now at UB is to transfer these solutions and to develop new ones where none exist at present."The project funded by the National Science Foundation_____________.A:was first proposed by some engineers at UBB:took about two days to completeC:was to investigate the damage caused by the terrorist attackD:was to find out why some buildings could survive the blasts

第一篇How to Do with Earthquake?Ideally,people would like to know when an earthquake is going to happen and how bad it willbe.In both Japan and China,people have long believed that earthquakes can be forecast. In Japan, scientists have wired the Earth and sea to detect movements.The Chinese have traditionally watched animals and plants for warning signs of earthquakes.For example,the Chinese have noted that before an earthquake,hens' behavior changes一they refuse to enter their cages at night. They have also noticed that snakes come out of the ground to freeze to death and that dogs bark a lot,even normally quiet dogs.Before the Hanshin earthquake in Japan,there were reports of large schools of fish swimming near the surface of the water. Certain birds,like pigeons,also seemed to be especially noisy and were reported to be flying in unusual patterns before the earthquake.Perhaps most interesting,and most easily measured,is a chemical change in ground water before a quake.Experimental data seem to indicate that the amount of radon(Rn)in the water under the surface of the Earth waxes before an earthquake.People would also like to be able to prevent the great destruction of property caused by earthquakes.After all,most of the people who die in earthquakes are killed by falling buildings.Therefore,building structures that can withstand the power of earthquakes is a major concern.Steel seems to be the best material,but not if it is welded to form a rigid structure.Many new structures are built with a new type of steel joint,an I-joint,which appears to be the most durable type of joint. These joints of steel can move without breaking. Also,to prevent property damage,architects now design buildings so that the building's columns and horizontal beams are of equal strength,and vertical support columns are inserted deep into solid soil.In addition,many new houses have relatively light roofs and strong walls.Concrete pillars for highway bridges that previously only had steel rods inside are now enclosed in steel.Besides working to improve building structures,people in areas where earthquakes are common need to prepare for the possibility of a great earthquake.They should regularly check and reinforce their homes,place heavy objects in low positions,attach cupboards and cabinets to walls,and fasten doors so that they will not open accidentally during an earthquake.According to the passage,the amount of radon(Rn)in the water may______before earthquake.A:increase B:reduce C:not change D:disappear

Earthquake Insurance1.Earthquake insurance is a form of homeowners' insurance which deals with damage caused by earthquakes.In regions where earthquakes are especially common,homeowners may be required to carry earthquake insurance,so that in the event of an earthquake,people rely less on government disaster funds and more on their own insurance policies.As a general rule,earthquake insurance is not a part of standard insurance policies,and it must be purchased separately.2.Earthquakes can cause a variety of damage to a home,ranging from complete destruction to damage which causes the building to become structurally unsound.Indirect damage caused by neigh-boring collapses of structures and freeways can also occur,as can more bizarre forms of earthquake damage,like winding up with a car in the living room or a sinkhole in the back yard.Fires and flooding are also common problems in the wake of earthquakes.3.When homeowners purchase earthquake insurance,they may be protected against both direct damage,such as a structural collapse after an earthquake,and indirect damage,like a fire caused by broken gas lines.More commonly,the insurance only covers structural damage caused directly by the earthquake.The insurance may pay for a complete replacement of the structure,or a remodel, depending on the type of insurance and the nature of the damage.Some policies also cover damaged property like cars,and they may provide living allowances so that the residents of the home can temporarily relocate for the duration of the repairs.4.This type of homeowners' insurance is prone to adverse selection,in which only people in high risk areas purchase the insurance.The problem with adverse selection for insurance companies is that it decreases the pool of customers,making potential payouts very expensive.For this reason, earthquake insurance often has a high deductible,and it can he very expensive.5.Recognizing the need for earthquake insurance,some governments have provided subsidies for earthquake insurance,to reduce the stress on insurance companies.Insurance companies also adjust their risk pools carefully,and there may be stringent requirements for a homeowner to purchase earthquake insurance.For example,a home may need to be retrofitted for earthquake safety, reducing the amount of damage which will be incurred in a quake.For low-income home owners, this can be very difficult,as it drives the cost of earthquake insurance out of reach,which can in turn make it difficult to get home loans,as many banks in earthquake-prone areas insist on earth-quake insurance as a condition for a loan.Paragraph 3______A:What's the Main Problem of Earthquake Insurance?B:What Damages Can an Earthquake Cause?C:How to Buy an Earthquake Insurance?D:What Is an Earthquake Insurance?E:Where Does Earthquake Happen Frequently?

问答题Read the passage carefully and answer questions 1 to 5. Answer each question in a maximum of 10 words. Remember to write the answers on the answer sheet. Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world. Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of vibration. Other damage results from landslides, tsunamis (large ocean waves) or major fires which are initiated by the quake. There are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from 0 upward. The highest magnitude recorded to date is 8.9. Major damage generally occurs from quakes ranging upwards from 6. 0. Exceptions to this are those whose epicenters are located far from inhabited areas. The actual cause of the quake itself is the rupturing or breaking of rocks at or below the earth’s surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the expansion and contraction of the earth’s crust and continental drift. In order to minimize the damage and to alleviate some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction. Two of the instruments presently in use to achieve this goal are seismographs and tiltmeters. The former records any shaking of the earth; by means of calculations seismologists can accurately indicate the exact time, location and size of an earthquake. The latter, as the name suggests, is used to record any changes in the tilt of the land. Questions: 1．Write down one of the two earthquake prone areas. 2．What other disasters may occur after a serious earthquake? 3．What is the unit of measurement of earthquake? 4．What is the highest magnitude in the record? 5．What are the two instruments used today to predict earthquake?
