问题 We have to be careful in driving a car mainly because it could be ______. [br] According to the passage, air bags are another device that ______.

选项 A、adds safety to car driving
B、is going to replace seat belts
C、comes out slowly to function
D、prevents cars from running too fast

答案 A

解析本题为细节题。由题干air bags定位到文章第四段的第二句话“Air bags are also very important for car safety”“气囊对汽车安全也非常重要”此句叙述与选项A一致。B、C、D项不是气囊的真正用途．因此，答案是A。
