2020秋高中英语Unit5Firstaid同步练习含解析新人教版必修5

Unit 5 First aid
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 life­critical 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 non­conductive 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.

Li Hua 答案：
Dear John，
I am glad to receive your letter，and now I'll tell you something about the first aid course in our school and some suggestions about first degree burns.
The first aid course is a necessary part of our education.If we have learnt about first aid，we can help someone who has had an accident，and even can save someone's life one day.
The suggestions about first degree burns are as follows.Cool the burned area at once.Place the affected area under cold running water for 15 minutes or so.You'd better go to hospital if the affected area is still painful.
The first aid course is very interesting and useful.Would you like to come here to study again? We are all looking forward to it.
Best wishes，
Yours，
Li Hua
