• 22．Doctors in hospital emergency rooms（急診室） often see accidental poisonings（中毒）.A frightened parent arrives with a child who swallowed a cleaning liquid.Or perhaps the harmful substance is a medicine.Or it might be a product meant to kill insects.These are common causes of accidental poisonings.
     In cases like these，seek medical help as soon as possible.Save the container of whatever caused the poisoning.And look on the container for information about anything that stops the effects of the poison.Save anything expelled from the mouth of the victim.That way，doctors can examine it.
     Millions of people know how to give abdominal thrusts（腹部按壓） to save a person choking on something trapped in the throat.The American Red Cross says a rescuer should first hit the person on the back five times between the shoulder bones.If the airway is still blocked，the Red Cross suggests pushing hard five times along the victim's abdomen.You can do these abdominal thrusts by getting directly behind a sitting or standing person.
     The Mayo Clinic health centres suggest several steps if bleeding is severe.First，if possible，remove dirt from the wound and press on it with a clean cloth or piece of clothjye.aig.In the past，people were advised to stop severe bleeding with a tourniquet（止血帶）.But experts now say tourniquets are dangerous because they can crush（擠壓） major arteries and nerves.If a wound seems infected，let the victim rest.Physical activity can spread the infection.Treat the wound with a mixture of salt and water until medical help arrives.
     To learn more about first aid，ask a hospital or an organisation like a Red Cross or a Red Crescent Society for information.Training may be offered in your area.
  
  （1）Which of the following is NOT the cause of accidental poisonings？

• 23．It was a cold March day in High Point，North Carolina.The girls on the Wesleyan Academy softball team were waiting for their next turns at bat during practice，stamping their feet to stay warm.Eighth-grader Taylor Bisbee shivered（發(fā)抖） a little as she watched her teammate Paris White play.The two didn't know each other well—Taylor had just moved to town a month or so before.
     Suddenly，Paris fell to the ground. "Paris's eyes rolled back，" Taylor says. "She started shaking.I knew it was an emergency."
     It certainly was.Paris had suffered a sudden heart failure.Without immediate medical care，Paris would die.At first，no one moved.The girls were in shock.Then the softball coach shouted out， "Does anyone know CPR？"
     CPR is a life-saving technique.To do CPR，you press on the sick person's chest so that blood moves through the body and takes oxygen to organs.Without oxygen，the brain is damaged quickly.
     Amazingly，Taylor had just taken a CPR course the day before.Still，she hesitated.She didn't think she knew it well enough.But when no one else came forward，Taylor ran to Paris and began doing CPR. "It was scary.I knew it was the difference between life and death，" says Taylor.
     Taylor's swift action helped her teammates calm down.One girl called 911.Two more ran to get the school nurse，who brought a defibrillator，an electronic device（器械） that can shock the heart back into work.Luck stayed with them：Paris's heartbeat returned.
     "I know I was really lucky，" Paris says now. "Most people don't survive this.My team saved my life."
     Experts say Paris is right：For a sudden heart failure，the single best chance for survival is having someone nearby step in and do CPR quickly.
     Today，Paris is back on the softball team.Taylor will apply to college soon.She wants to be a nurse. "I feel more confident in my actions now，" Taylor says. "I know I can act under pressure in a scary situation."
