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.

【正确答案】
D
【答案解析】解析：这是一道考察细节的题型。题干要求：文章中建议乘客在飞机起飞之前应该对哪个安全出口进行定位?在文章中第一段最后一句“Before takeoff you should locate the nearest exit and an alternative exit and count the lOWS of seats between you and the exits…”．可以得出选项B不全面。只有D项最符合题意。

According to the passage, people have more chances to survive fires in aircraft if they
【正确答案】
B
【答案解析】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。

Airline passengers are specifically told NOT to________.
【正确答案】
A
【答案解析】解析：依然是一道考察细节的题型。题干：乘客被特别告诫不要做什么?首先选项A，“在紧急情况下携带个人随身物品”。在短文第二段中有“To evacuate as quickly as possible，follow crew commands and do not take personal belongings with you．”即“遵照机组人员的指挥尽快撤离，撤离时请勿携带个人随身物品”，由此可得正确答案是选项A。选项B中“对最近的出口进行提问”是文章中明确建议乘客做的。文章第一段第三句“专家认为乘客应该在飞机起飞前阅读并聆听乘机安全指导，如有疑问可向相关人员咨询”，可见C项也不是本题的正确答案。选项D，“在任何情况下跳机”明显违背文章内容，因为第二段中讲“Do not jump on escape slides before they are fully inflated，and when you jump，o0 so with your arms and legs extended in front of you．”，后半句中说乘客跳机时，四肢要向前伸展，可得知是可以跳的，而不是说任何情况下都不能跳。
