someones airway can save their life while theyre waiting for emergency medical help. knowing what to do will allow you to react rapidly if an accident does happen. however, there are also many misconceptions(误解) surrounding first aid，some of which can cause more serious harm.1if you cant move a limb, it must be broken. if you can move a limb，it cant be broken. the only accurate way to diagnose a broken limb is to xray it.2the best way to treat bleeding is to put the wound under a tap. if you put a bleeding wound under a tap you wash away the bodys clotting agents and make it bleed more.3nosebleeds are best treated by putting the head back. if you put the head back during a nosebleed，all the blood goes down the back of the airway.4a tourniquet is the best way to treat serious bleeding. its harmful to stop the blood flow to a limb for more than 1015 minutes.5if someone has swallowed a poison you should make him or her sick. if you make someone sick by putting your fingers in their mouth, the vomit(吐出物)may block their airway.6if you perform cpr on someone who has a pulse, you can damage his or her heart. the evidence is that it isnt dangerous to do chest compressions on a casualty with a pulse.7you need lots of training to do first aid. you need lots of expensive equipment to do first aid. you dontwhat you mostly need is common sense.16in the passage, cpr must mean_.achest compressionsbsome action causing damage to the heartcfirst aidda kind of equipment17which of the following actions is proper?aif your nose is bleeding, put the head back.blet me put my fingers in your mouth to make the poison out.cgo to the tap to stop bleeding.dperform cpr on her, although she has a pulse. 18in the authors opinion, first aid should be given _.aafter emergency medical help arrivesbby professional doctors with expensive equipmentcproperly and rapidlydto slightly injured people only19the passage focuses on _. aproving the importance of first aidbcorrecting misunderstanding on first aidcexplaining what first aid isdteaching how to give first aid20which action should be taken to diagnose a broken limb?aput the broken limb in splints.bmove the limb.cperform cpr.dxray it.bit is difficult for doctors to help a person with a damaged brain. without enough blood, the brain lives for only three to five minutes. more often the doctors cant fix the damage. sometimes they are afraid to try something to help because it is dangerous to work on the brain. the doctors might make the person worse if he operates on the brain.dr robert white, a famous professor and doctor, thinks he knows a way to help. he thinks doctors should make the brain very cold. if it is very cold, the brain can live without blood for 30 minutes. this gives the doctor a longer time to do something for the brain.dr white tried his idea on 13 monkeys. first he taught them to do different jobs, then he operated on them. he made the monkeys blood go through a machine. the machine cooled the blood. then the machine sent the blood back to the monkeys brains. when the brains temperature was 10， dr white stopped the blood to the brain. after 30 minutes he turned the blood back on. he warmed the blood again. after their operations the monkeys were like they had been before. they were healthy and busy. each one could still do the jobs the doctor had taught them.21the biggest difficulty in operating on the damaged brain is that _.athe time is too short for doctorsbthe patients are often too nervouscthe damage is extremely hard to fixdthe bloodcooling machine might break down22the brain operation was made possible mainly by _.ataking the blood out of the brainbtrying the operation on monkeys firstchaving the blood go through a machinedlowering the brains temperature23with dr whites new idea, the operation on the damaged brain _.acan last as long as 30 minutesbcan keep the brains blood warmccan keep the patients brain healthydcan help monkeys do different jobs24what is the right order of the steps in the operation?asend the cooled blood back to the brainbstop the blood to the brainchave the blood cooled downdoperate on the brainaa, b, c, d bc, a, b, dcc, b, d, a db, c, d, a25. which of the following is not true?aif there isnt enough blood, the brain can live for only three to five minutes.bif the brain is very cold, it can live without blood for half an hour.cdr white tried his idea for thirteen times.dafter their operations, the monkeys were healthy and busy again.答案课时作业(二十五)
