Forces other than damaging winds are also at work inside tornadoes (龙卷风) . Sometimes,as the wind passes a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado.The pressure at the center of a tornado is usually 13 pounds per square inch. However,inside the house the air pressure is normal, about 15 pounds per square inch.The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado passes over a small building that measures 20 by 10 by feet. On each square inch of the building, there is 2 pounds of pressure from the insidethat is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57600 pounds. The pressure of the four walls adds up to 172800 pounds.If windows are open in the building, some of the inside air will rush out through them.This will balance the pressure inside and outside the building.But if the windows are shut tightly, the huge inside pressure may cause the building to burst.Unfortunately, heavy rain often occurs in the storms that later produce tornadoes,so people often shut their windows. This may cause far worse damage later.21、 What did the paragraph before this passage most probably discuss?A、 Measuring rainfall from a stormB、 The kinds of damage caused by explosionsC、 The powerful winds of tornadoes22、 Which of the following is the main topic of the passage?A、 How tornadoes can be preventedB、 When tornadoes usually occurC、 Why tornadoes cause so much damage23、 Tornadoes can destroy buildings because the()A、 force of a tornado increases the air pressure in a buildingB、 air pressure inside a tornado is less than the air pressure inside a buildingC、 air pressure at the center of a tornado is over 172000 pounds24、 What is the difference per square inch between the air pressure inside a building and the air pressure inside a tornado?A、 2 poundsB、 13 poundsC、 15 pounds25、 What would happen if the windows are shut tightly in the stormy weather?A、 Tornadoes may be formedB、 The house may be apartC、 There may not be any pressure inside the building

共用题干Some Schooling on BackpacksAccording to the U.S.Consumer Product Safety Commission,5,900 kids were treated at hospital emergency rooms , clinics , and doctors ' offices last year for sprains（扭伤）and strains caused by backpacks.Such injuries are so widespread that more than 70 percent of physicians'surveyed by the American Academy of Orthopedic（整形外科的）Surgeons listed backpacks as a potential clinical problem for children.How do you avoid such problems? Choose bags that have wide , padded straps（有垫的背带）and a belt.That will help transfer some of the weight from the back and shoulders to the hips.You should also tighten both straps firmly,so the pack rests about 2 inches above your waist.Also,remember to pack your bag with the heaviest items closest to your back and to bend both knees when you pick it up.How much should you stuff into your pack?That depends on your size and strength,but a general rule is not to exceed 20 percent of your body weight.So if a child weighs 100 pounds,the backpack and its load should not be more than 20 pounds.One hint : Make frequent trips to your locker（储物柜）to exchange books between classes.Backpacks with wheels let you pull the weight along the ground,but they have problems too.Many are larger than the average shoulder bag,so students are tempted to carry more than they would in a conventional pack.Roller bags often don't fit into a locker.They can also lead to tripping and falls in crowded halls.Whatever you use,10 or 15 minutes of stretching and back strengthening is a good idea.A 100-pound child should carry a backpack of more than 20 pounds.A:Right B:Wrong C:Not mentioned
