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.Why are building structures a major concern for people?A:Because they can make buildings pleasing to people's eyes.B:Because people are often killed by falling buildings in earthquakes.C:Because sometimes they are costly.D:Because people want to cut budget by designing new types of buildings.
Although dolphins sometimes swim singly or in pairs,they usually congregate in large herds,often numbering in the hundreds.A:procreateB:eatC:liveD:assemble

资料：Stress is a common factor in life. Children experience stress from school, new social situations and simply growing up. Adults feel the stress of working, paying bills, raising kids and maintaining households. Seniors also feel stress, even though some may have retired, raised their children and paid off their homes. Certain amounts of stress are a part of life for people of all ages.For seniors, stress has the potential to be especially overwhelming. This type of tension in older adults has unique contributing factors, such as the loss of an elderly spouse or friends. Living alone can increase the sense of isolation. Sometimes the simple tasks of everyday life can cause stress in those who experience physical or medical limitations. The effects of stress can sometimes exacerbate health conditions from which some seniors suffer, causing additional worry.Stress can be detected in various ways. You may follow the five most common ways to find out if a loved one’s stress is cause for concern:1. Changes in eating habits, such as over-eating or loss of appetite, can be caused by overwhelming stress.2. Mood swings due to stress may present in increased irritability, general sadness or depression.3. Memory issues may arise in the form of increased forgetfulness of names, places or other things that normally come naturally. Lack of concentration may become a problem. Some seniors may exercise poor judgment, such as excessive spending when they are already on a limited budget.4. Physical signs of stress can include body aches and pains or increased episodes of illness. Changes in sleeping patterns—either trouble falling asleep or interrupted nighttime sleep—can signal significant stress.5. Seniors experiencing overwhelming stress often isolate themselves from others, refusing to socialize or participate in activities they used to enjoy.What does the word “exacerbate”（Line 4, Paragraph 2） probably mean?A.AffectB.ImproveC.IntensifyD.Worsen

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?

问答题Practice 1 How does an earthquake start? What makes an earthquake happen? The rock of the earth’s crust (地壳) may have a “fault”, a kind of break in the surface. The blocks which make up the earth move, and sometimes this may cause the sides of the fault to move up and down or lengthways (纵向地) against each other. When one piece of rock starts to rub on another with great force, a lot of energy is used. This energy is changed into vibrations (振动) and it is these vibrations that we feel as an earthquake. The vibrations can travel thousands of kilometers and so an earthquake in Turkey may be felt in Greece. What to do during an earthquake? At school As soon as the earthquake starts, students should get under the desks immediately and wait until the teacher tells them it is safe to come out. The teacher should, at the same time, go immediately to the teacher’s desk, get underneath (在……下面) it and stay there till the danger is over. Students must not argue with the teacher or question instructions. As soon as the tremors (震动) stop, all students should walk towards the exit and go straight to the school playground or any open space such as a square or a park. They must wait there until the teacher tells them it is sale to go. At home If you are at home when the earthquake occurs, get immediately under the table in the living room or kitchen. Choose the biggest and strongest table you can find. You must not go anywhere near the window and don’t go out onto the balcony (阳台). Once the tremors have stopped, you can come out from under the table, but you must leave the building straight away. You should walk down the stairs and should not use the lift—there may be a power cut as a result of the earthquake and you could find yourself trapped inside the lift for hours. In the street If you are in the street when the earthquake takes place, do not stand near buildings, fences or walls—move away as quickly as possible and try to find a large open space to wait in. Standing under trees could also be dangerous.
