Text 4The U.S. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. The areas of the map where government is spending a great deal of money and is working hard to help discover the answer to these two questions:1. Can we predict earthquakes?2. Can we control earthquakes?To answer the first question, scientists are looking very closely at the most active fault systems in the country, such as the San Andreas fault in California. A fault is a break between two sections of the earth's surface. These breaks between sections are the places where earthquakes occur.Scientists look at the faults for changes which might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes accurately and the control of earthquakes is even farther away.Nevertheless, there have been some interesting developments in the field of controlling earthquakes. The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water was pat into a layer of rocks 4,000 metres below the surface of the ground. Shortly after this injection of water, there was a small number of earthquakes. Scientists have decided that the water which was injected into the rocks worked like oil on each other. When the water" oiled" the fault, the fault became slippery and the energy of an earthquake was released.Scientists are still experimenting at the site of these earthquakes. They have realized that there is a connection between the injection of the water and the earthquake activity. They have suggested that it might be possible to use this knowledge to prevent very big, destructive earthquakes, that is, scientists Could inject some kind of fluid like water into faults and change one big earthquake into a number of small, harmless earthquakes.36. Earthquake belts are ______.A) maps that show where earthquakes are likely to occurB) zones with a high probability of earthquakesC) breaks between two sections of the earth's surfaceD) the two layers of earth along a fault
共用题干第一篇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

共用题干第二篇High Stress May Damage MemoryAccording to a report issued in May 1998,elderly people who have consistently high blood levels of cortisol (皮质醇）don't score as well on memory tests as their peers with lower levels of the stress hormone. What's more,high levels of cortisol are also associated with shrinking of the hippocampus（海马区）,a region of the brain that plays a key role in learning and memory.The findings suggest that even cortisol levels in the normal,"healthy"range can actually accelerate brain aging.The study results"now provide substantial evidence that long-term exposure to adrenal(肾上腺的）stress hormones may promote hippocampal aging in normal elderly humans", write Nada Porter and Philip Landfield.Cortisol is a hormone released in response to stress by the adrenal glands（腺）,which sit on top of the kidneys(肾）.Over a 5-to 6-year period,Dr. Sonia Lupien and his colleagues measured 24-hour cortisol levels in 51 healthy volunteers,most of whom were in their 70s.The researchers tested the volunteers' memory on six people in the increasing/high category and five people in the decreasing/moderate group.The groups did not differ in tests of immediate memory,but the increasing/high cortisol group had other memory problems compared with those in the decreasing/moderate group.The researchers also found that the total volume of the hippocampus in those in the increasing/high group was 14% lower than those in the decreasing/moderate group, although there were no differences in other brain regions.The results suggest that“…brain aging can be accelerated by levels of adrenalhormones that are not generally regarded as pathological（病态的）and that variation within this normal range is related to variation in the rate of brain aging",write Porter and Landfield."This further suggests that chronic stress may accelerate the worsening of the hippocampus."

共用题干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?

单选题Which of the following statements is true according to the passage?AEarthquake destruction is declining.BEarthquake forecast is improving.CMan is no longer fearful of earthquakes.DMan is capable of conquering earthquakes.
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?
