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.
What is the main purpose of the passage? _______ .
选项 A、To guide people to survive fires.
B、To provide safety advice.
C、To please travelers.
D、To give the information of airline industry statistics.
答案B
解析 这是一道提炼主旨的题型。这里可用到排除法，先通读四个选项，然后根据文中的信息进行排除。首先A项不准确，因为文中只在第二段中间部分提到如果机舱内有烟应采取什么措施，而其他部分则都没有提到与火有关的内容，因此不准确，可以排除。选项C，“为了取悦旅行者”，这显然不是文章的主旨，因为乘机安全知识关系到生命这个严肃的问题，与“取悦”无关。选项D中说给出航空业的统计数据，这个只在文章开头提到一个数据，目的是说明安全知识对提高航空事故中生还几率的重要性。纵观全文，大量信息其实是在第一段和第二段，里面给大家提出各种安全建议，因此选项B最符合题意。
