【简答题】

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( 发抖 ) 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 devices( 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 .” 1 . What happened to Paris on a March day? A . She caught a bad cold . B . She had a sudden heart problem . C . She was knocked down by a ball . D . She shivered terribly during practice . 2 . Why does Paris say she was lucky? A . She made a worthy friend . B . She recovered from shock . C . She received immediate CPR . D . She came back on the softball team . 3 . Which of the following words can best describe Taylor? A .
