阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
In daily life, there are some emergencies that you might have to deal with one day. Learn to handle the emergencies below for yourself, your family and friends.
Sudden heart attack
Having CPR training is the life-saving help for someone having a heart attack. Move the patient’s head back and look for breathing. If the patient doesn’t take a breath in less than 10 seconds, start CPR. Put your hands on the center of the chest. Push hard and fast — about twice per second. Push on the chest 30 times and then give mouth-to-mouth 2 times. Repeat cycles of the presses and mouth-to-mouth until the help arrives or the patient wakes up.
Choke
Stand behind the choking person. Put your arms around the waist and bend him or her slightly forward so that the object blocking the airway will move out of the mouth. Do this up to five times. You can also do back blows — firmly slap the person on the back with your hand while he or she is bent over. If the object still doesn’t come out, call 120.
Nosebleed
Ask the person to lean forward and pinch (捏) his nose for five to six minutes. Do not move his head backward, as the blood may run into his mouth or even his lungs. Encourage the person not to speak, swallow, cough or spit because these may break blood clots (血块) that may have started to form in the nose. If the bleeding lasts more than 30 minutes, call 120 for medical help.
Burn
Burns should be treated by an adult — the injured area should be put under cool running water for 10 to 15 minutes to relieve the pain. Ice should never be used, as it can make the injury even worse. If a child has a serious burn, he or she should be taken to a doctor or the emergency room.
1. How often should you push on the chest when you perform CPR?
A. Once a second.
B. Twice a second.
C. Once every two seconds.
D. Once every three seconds.
2. What can you do to help a choking person?
A. Do some back blows.
B. Ask him or her to drink some water.
C. Press his or her stomach and back at the same time.
D. Help him or her bend forward as much as possible.
3. According to the text, what is the first thing to do with a slight burn?
A. Put it under cool running water.
B. Put an ice pack on it.
C. Wrap it in a cloth.
D. Call a doctor for help.
B
