When you run and play in the field, you may sometimes fall and bruise your knee. Small cuts and minor grazes are unavoidable in our daily life. Such cuts and grazes will usually need little or no treatment. The bleeding will clean the wound naturally, and it should stop within a few minutes, as the blood clots and dries. More serious cuts may need to be gently cleaned with soft cotton and warm water. They should then be dressed with a clean cotton bandage.

part Ⅱ Kiss of life
Anyone whose breathing has stopped needs artificial respiration at once. Breathing can stop from one of many reasons: drowning, electric shock, poisoning, suffocation or a sudden illness such as a heart attack. Lack of oxygen can cause brain damage within only three to five minutes and longer oxygen starvation leads to death.
A You are going to hear someone telling you how to give artificial respiration. While listening for the first time, add more key words in the notes column. After the second listening, arrange the pictures in the correct order.
To check whether a person is breathing, you may put your ear close to his nose and mouth: you should be able to hear air passing in and out of his throat. Or you may put a mirror close to his lips: if he is breathing, the mirror mists over.
B Now try this: listen to an authentic version of a dialogue. A swimming instructor is demonstrating artificial respiration for two students. Listen carefully. Complete each step for artificial respiration.
● Get the person lying ___________. Check for breathing. Listen at ___________.

Part Ⅳ More about the topic: Treating Shock
When you suddenly have an experience which is unpleasant, upsetting, or very surprising, you have a shock. However, in medicine, shock is a serious physical condition in which your blood cannot circulate properly, for example, because you have had a bad injury.
The following passage gives you some hints on how to treat shock. Supply the missing words while listening.
Right, tonight we're going to look at the problem of shock. In medical terms, ______ isn't just emotional upset. It is a very definite physical condition in which the ______ and the circulation gradually lose _______ Gradually the patient becomes pale and cold, drowsy, and perhaps he or __________ even loses consciousness. Shock can result from all major __________ -bleeding, wounds, burns and fractures -and the speed of the patient's deterioration depends on the severity of the _______ So whenever someone has been badly injured, you must do ________ things: you must give specific help for the actual ________ itself, and you must also do something to halt or at least to try and ________ the shock process. Now here's one or two hints on ______ to do this.
First of all, you _______ move the patient unless you absolutely have to. If you're in a burning house or in the middle of a motorway, you'll have to ______ him, of course. But otherwise treat him where he is until the doctor or the ambulance _______. And the next thing to remember is that you should position the patient ______ down with his head low and his feet raised. This is to ______ the blood flow to the heart, lungs and brain. But _______, of course, be tempted to move any part that might be fractured. Be careful always of that. _________ any tight clothing, such as braces, belt, collar, or even-you'll be surprised to learn nowadays-corsets. This will ________ the patient more comfortable and allow him to ________ more easily.
Keep the patient warm by _________ a blanket or coat loosely over them. If he's lying on a cold surface, then try to _________ something underneath him as well. But again, do that very gently. _________ use hot-water bottles, because hot-water bottles actually _________ blood away from the internal organs towards the skin surface. So although that may sound like a commonsense thing to do, it actually ________.
Reassure the patient, this is very important, by being _________ yourself, confident, methodical and, above everything, sympathetic the whole time. Even if the patient seems to be _________, they may be able to hear any unfavorable comments you make, in _______ fact. And if he hears or sees you whispering, then he's bound to imagine the worst. He'll be in a very ________ state and this will make his condition _______ too.
And the final ______ to remember is that you must not give anything at all by ______. Any sort of drink, whether alcohol or tea or ______, may be vomited up, causing choking. And it may also complicate _________ if an anaesthetic is needed later in _________. So all the old wives' tales you've heard about administering brandy, forget them. If the ________ feels dry and he says he's thirsty, or you suspect that they may be thirsty, you can allow him to suck gently a ________ or a sponge moistened with water.
