IS Your HOME SAFE?Your home can be a dangerous place. But, if you understand what you can do to make your home safer, you can prevent accidents. And always keep a first-aid kit in your home- just in case there is an accident.The kitchen, bathroom and bedroom are the most unsafe places. Common accidents in these rooms include falls, fires, poisoning, cuts hot water burns and electric shocks.THE KITCHENMake sure the floor is not slippery.Always use a ladder to reach high cupboards; never stand on a chair.Turn saucepan handles away from the front of the stove. Always cut away from your body when you use a knife. Follow instructions for all electrical appliances carefully. Unplug all appliances, especially irons, after use.Keep matches out of the reach of childrenStore all cleaning materials and poisonous materials in a locked cupboard.THE BEDROOMNever smoke in bed.Keep a lamp near the bed.Unplug electric blankets when not in use.Have a telephone near the bed, especially if ill.THE BATHROOMDon’t plug in an electrical appliance or use it while standing in water.Don’t use a hair dryer near a bath containing water.Never leave a small child alone in the bath.PREVENTING FIRESFires can cause terrible damage to your home and terrible injuries to people. But people are more important than things; so there is a fire, get everyone out of the house safely. Then call for help. Never go back into a burning building to save your things. Have fire extinguishers in the house.Buy clothes, curtains and toys that do not burn easily.Put screens in front of fires.Use heats very carefully as they can set objects on fire. Place them away from furniture.When cooking, do not let oil touch flames or other sources of heat.Check electrical wires a number of times a year to make sure they are in good condition.Put covers over electrical outlets if young children are at home.你家里可能是一个危险地方。
Never try and reset a broken bone.Remember,this is first aid—if you are doing this,you are preparing a patient for transport.Unless you are 100% sure of what you are doing,resetting a broken bone runs a strong risk of making things worse.It is dangerous to give aspirin(阿司匹林) to anyone under the age of 16 as it can potentially cause damage to the brain and liver before this age.Never,ever put yourself in danger!As much as this seems to lack compassion(同情),remember that being a hero,in this case,means nothing if you come back dead.If you aren’t sure what to do,leave it to the professionals.If it’s not a life-critical injury,doing the wrong thing can harm the patient.See the following tips about training.Do not move the person.It could harm them even more;unless they are in immediate danger.Wait for the ambulance to arrive to take over treatment of the person.Do not touch someone who is being shocked by an electrical current.Turn off the power or use a piece of non-conductive material (e.g.,wood,dry rope,dry clothing) to separate him from the power source before touching him.Before touching a victim or offering any aid,get permission to treat! Check the laws in your area.If someone has a “Do not resuscitate(使复苏)” order,respect it.If the person is unconscious and at risk of death or injury,without any known “Do not resuscitate” order,go ahead and treat by the permission.阅读短文,判断正(T)误(F)1.When you are trying to give first aid,you must not put yourself in danger.(T)2.If you aren’t sure what to do,you’d better wait for the professionals.(T)Period One Warming Up & Reading—Pre-reading匹配左边的单词与右边的汉语意思[第一组]1.sprain A.暂时的;临时的2.ankle B.流血3.choke C.扭伤4.temporary D.踝(关节)5.bleed E.(使)噎住;(使)窒息答案 1.C 2.D 3.E 4.A 5.B[第二组]6.complex A.橱柜;衣柜7.ray B.器官8.organ C.屏障;障碍(物)9.cupboard D.光线;射线10.barrier E.复杂的答案 6.E7.D8.B9.A10.C[第三组]11.liquid A.液体12.swell B.轻微的;温和的;温柔的13.tissue C.炉子;火炉14.mild D.(生物)组织;薄的织物;手巾纸15.stove E.(使)膨胀;隆起答案11.A12.E13.D14.B15.C[第四组]16.damp A.神经;胆量17.vital B.剪刀18.symptom C.至关重要的;生死攸关的19.nerve D.症状;征兆20.scissors E.潮湿的答案16.E17.C18.D19.A20.BStep 1Fast-reading1.What’s the main idea of the text?A.It’s about the types of burns.B.It’s about the symptoms of burns.C.It’s about the burns and the first aid treatment.D.It’s about the treatment of burns.答案 C2.Put the following sentences into right orders according to the passage.(3)The three types of burns(5)What to do if someone gets burned(1)The functions of the skin(4)The symptoms of burns(2)How we get burnsStep 2Careful-readingⅠ.Read the passage and judge whetherthe following sentences are true (T) or false (F).1.When someone is burned,you should place some ice on his wound.(F)2.One of the functions of cool water is to reduce swelling.(T)3.We should put damp cloths on the second degree burns.(T)4.We shouldn’t break the blisters,or they might make the wound infected.(T) 5.Sometimes,we can put oil or ointment on burns to stop the infection.(F)6.We should make sure the bandage won’t stick to the skin when it is used.(T)7.If burns are on arms or legs,keep them higher than the heart if it is possible.(T) 8.Cold water can be used in all three types of burns.(F)Ⅱ.Read the passage carefully and choose the best answers.1.Which of the following is NOT the cause of burns?A.Steam and radiation.B.The moon and the sun.C.Fire and electricity.D.Hot liquids and chemicals.答案 B2.What are the characteristics of first degree burns?A.Black and white and charred.B.Rough,red and swollen.C.Rough,red and dry.D.Dry,red and mildly swollen.答案 D3.If burns affect all three layers of the skin and any tissue and organs under the skin,someone must .A.be sent to hospital at onceB.be placed on the floor and cool the burns immediatelyC.be undressed in order to cover the burned area with a clean,dry bandageD.be asked not to drink any water答案 A4.Why should we dry the burned area gently?A.Because the person will cry.B.Because rubbing may break any blisters and the wound may get infected.C.Because the burns are on the face.D.Because it will make the person feel good.答案 B5.Which of the following first aid treatments is RIGHT according to the text?A.Take clothing off the burned area even though it is stuck to the burn.B.Do not put cold water on second degree burns.C.If burns are on the face,the victim should sit up.D.If the injuries are second degree burns,it is unnecessary to get the victim to the doctor or hospital at once.答案 CStep 3Post-readingAfter reading the passage,please fill in the following blanks.First aid is a kind of help 1.given(give) to someone who falls ill or gets injured 2.before a doctor can be found.Often the illness or injury is not serious.Now let’s talk about first aid for burns.You have three layers of skin that protect 3.yourself(you) against disease,poisons and the 4.harmful(harm) rays from the sun.Your skin also gives you your sense of touch.First aid is a very important first step in the treatment of burns.People can get burned by many things,5.such as hot liquids,steam,fire,radiation,the sun,electricity or chemicals.6.There are three types of burns.Burns 7.are called(call) first,second or third degree burns,8.depending(depend) on which layers of the skin are burned.Different degree burns can be treated in 9.a different way.Let’s keep these things 10.in mind.Step 4Sentence-learning1.Often the illness or injury is not serious,but there are other times when giving first aid quickly can save lives.[句式分析]本句是一个并列句,第一个并列分句是主系表结构;第二个并列分句是there be 结构,内含定语从句when giving first aid quickly can save lives,修饰times。
