First aid ( 急救 ) is the care given to the injured or sick as soon as possible after an accident or illness. It is this immediate care and attention before the arrival of the ambulance that sometimes means the difference between life and death, or a full or partial recovery. First aid has limitations, as not everybody is a doctor or expert, but it is a key element of the total medical system. The principle to be adopted in first aid is immediate action. By-standers ( 旁观者 ) or relatives not knowing what to do, or being too fearful to try, have unwisely contributed to unnecessary deaths and worse injuries. It is important that any action taken by the first aid provider is started as quickly as possible. Quick action is necessary to save life and parts of the body. One who is not breathing effectively, or is bleeding heavily, requires immediate help. If quick effective first aid is provided, then they have a much better chance of a good recovery. But it should be remembered that any action taken is to be most careful, and fright ( 恐慌 ) by the first aid provider and by-standers will not be good to the whole thing. Try to remain calm and think your actions through. A calm and controlled first aider will give everyone confidence that the event is being handled efficiently and effectively.1.The most important thing in providing first aid is to ( ).A、call for an ambulanceB、prevent bleedingC、know what to doD、act quickly2.According to the passage, some injured or sick people died as a result of ( )A、other people's hesitation to offer first aidB、unprofessional first aidC、unnecessary first aidD、unwise suggestions by by-standers3.The writer seems to suggest that if you don't know much about first aid, you should ( )A、call for help from professionals.B、still try to helpC、stand by and not try to helpD、learn it from a doctor4.While offering first aid, the helper should ( )A、be self-controlledB、have others to assist himC、have confidence in the sick personD、get rid of they by-sanders5.Which of the following is TRUE according to the passage ( )?A、One should not apply first aid to the injured without knowing the cause of the accident.B、It is easy to carry out first aid if one has the necessary facilities.C、First aid is an important part of the whole treatment.D、First aid may not be effective before a doctor or expert comes.
