问题     According to the airline industry statistics, almost 90% of airline accidents are survivable or partially survivable. But passengers can increase their chances of survival by learning and following certain tips. Experts say that you should read and listen to safety instructions before takeoff and ask questions if you have uncertainties. You should fasten your seat belt low on your hips as tightly as possible. Of course, you should also know how the release mechanism of your belt operates. During takeoffs and landings you are advised to keep your feet flat on the floor. Before takeoff you should locate the nearest exit and an alternative exit and count the rows of seats between you and the exits so that you can find them in the dark if necessary.
    In the event that you are forewarned of a possible accident, you should put your hands on your ankles and keep your head down until the plane comes to a complete stop. If smoke is present in the cabin, you should keep your head low and cover your face with napkins, towels, or clothing. If possible, wet these for added protection against smoke inhalation. To evacuate as quickly as possible, follow crew commands and do not take personal belongings with you. Do not jump on escape slides before they are fully inflated, and when you jump, do so with your arms and legs extended in front of you. When you get to the ground, you should move away from the plane as quickly as possible, and never smoke near the wreckage.
According to the passage, people have more chances to survive fires in aircraft if they

选项 A、keep their feet flat on the floor
B、keep their heads low
C、fasten their seat belts tightly
D、read airline safety statistics before takeoff

答案B

解析 同样是一道考察细节的题型。题干:根据本文,如果人们怎样做,就能够在飞机失火的情况下有更大的生还的机会?注意:题意强调是在飞机失火的情况下。选项A,“飞机起飞前阅读航空安全数据”。文中涉及到相关信息的地方是在第二段第二句“If smoke is present in the cabin.you should keep your head low and cover your face with napkins,towels,or clothing”,而第一句中也提到“如果您预先收到可能发生事故的警报,请您将双手放到踝关节处,并且直到飞机安全降落时要一直保持低头的姿势。”而机舱中冒烟会有发生事故的危险,综合这两处同时提到的注意事项就是:keep heads low,以此得出正确答案为B。
