2、 problems that do not need a physicians attention.Even a child can save a life by knowing what to do. For example, by rolling an unconscious persons head to one side, anyone can save that person from drowning in his own saliva or choking on his tongue. Many first-aid techniques are as simple. Others

3、 require preparation in advance, but almost anyone can learn most of the important roles and methods.PART : Basic Rules1. Do not panic: control your emotions.

If the victim has stopped breathing, check the mouth and throat with a finger for any obstruction; then begin artificial respiration which is part of the CPR-cardiopulmonary resuscitation- life support technique described below.PART : CPR

8、 and Life SupportThe first part of CPR, clearing the airways, and the second part, artificial respiration, are easy to learn and are useful for many life-threatening emergencies. But the third part, external heart massage, must be practiced in advance to he sure of using it properly and safely.If a

9、person collapses and stops breathing, begin the ABCs of CPR. Do not go beyond A (airway clearance. if breathing resumes. Do not go beyond B (mouth-to-mouth breathing. unless you are certain that the victim has no pulse. Use C (chest compression) only if you have prepared yourself in advance to do it

10、 properly. In all the steps, use proportionately lighter force for children.A. Airway Clearance1. Place the victim on his back and support the neck.2. Lift the neck and tilt the forehead backward, and then lift the chin upward. Do not lift or bend the neck if you think it might be injured. Push the

11、chin upward without moving the neck.3. Listen for breathing by placing your ear near the mouth; meanwhile, watch the chest for signs of movement. If the person is breathing, roll him carefully onto his side.4. If there is no sign of breathing or breathing is inadequate, open the mouth and remove any

12、 foreign material that may interfere with resuscitation.B. Mouth-to-Mouth Breathing1. With the victims head in the up position, pinch the nostrils closed, take a deep breath, and place your mouth tightly over his mouth. Then blow quickly and deeply four times. After each time, raise your mouth and l

13、et air escape from the victims mouth. Mouth-to-nose respiration may be used if the mouth cannot be opened or is badly injured. With small children, place your mouth over the mouth and nose.2. If you feel resistance to your breath, and the victims chest does not rise as you exhale or fall when you pa

14、use, the airway may still be obstructed. Bend the neck back farther and lift the chin higher. (Do not bend an infants neck too far back or the airway will close. ) If no obstruction is found, roll the victim on his side toward you and deliver four firm slaps between the shoulder blades.Then place th

15、e victim on his back again, put your fist just above the navel, and forcefully but carefully push once. These movements combined may force air out of the lungs and remove any object trapped deeper in the airway.3. After assuring an open airway, check for a pulse by placing your thumb and middle fing

16、er on the neck on either side of the windpipe. If there is a pulse, resume the inhalations anal exhalations at the rate of one cycle every five seconds, or 12 a minute. Use shallower breaths for children, about 20 a minute. Mouth-to-mouth resuscitation must not be stopped for more than 15 seconds in

17、 adults, proportionately less in children, until the victim is breathing on his own.4. If these signs are present.a. the victim is unconscious,b. you feel no pulse, andc. the chest does not rise and fall, you may decide to proceed to C. First yell for help.C. Chest Compression1.

18、victim.2. Place the heel of your hand just below the middle of the victims breastbone and your other hand on top of the first.

19、 over the chest, and give a firm push straight downward about two inches. Let the weight of your shoulders do the work rather than muscle power.4. Push downward about 60 to 80 times a minute. Do not stop until a pulse can be felt; if ribs have cracked, correct your position and proceed cautiously.5.

20、 Chest compression must be matched with mouth-to-mouth breathing. If there are two rescuers, one should give the mouth-to-mouth respiration at the rate of one exhalation for every five compressions. If you have no help, give two exhalations after every 15 compressions at the compression rate of abou

21、t 80 per minute. For small children the compression rate should be higher, about 100 to 125 a minute.6. DO not interrupt CPR for more than 15 seconds at a time.

In fact, it is at t

46、he Suns very center. It is here that is to be found the source of the energy that the Sun (37) pours out into space as light and heat. This energy is liberated at the center of the Sun as billions upon billions of nuclei of (38) atoms collide with each other and fuse together to form nuclei of heliu

47、m (氦). And, in doing so, it (39) some of the energy that is stored in the nuclei of atoms. The output of light and heat of the Sun requires that some 600 million tons of hydrogen be (40) into helium in the Sun every second. This the Sun has been doing for several thousands of millions of years.The n

48、uclear energy is released at the Suns center as high-energy gamma (41) , a form of electro-magnetic radiation like light and radio waves, only of very much shorter (42) . This gamma radiation is (43) by atoms inside the Sun, to be re-emitted at slightly longer wavelengths. This radiation, in its tur

49、n, is absorbed and reemitted. (44) , it passes through the X-ray part of the spectrum (频谱), eventually becoming light.
