Heart disease takes up about ______ of the in-flight medical emergencies on US flights. [br] The phrase "getting winded"(Para. 5) is closest in meaning to______.
选项
A、falling over
B、being out of breath
C、spraining the ankle
D、moving in a curving line
答案
B
解析
原文指出了测试身体是否足够健康去乘坐飞机的方法,结合全文中提到的飞机中气压低、含氧量低的特点,可以推断getting winded应指“喘气”,即选项B。选项A和c都与身体状况有关,但是任何普通人走150米的路和爬一段楼梯然后摔倒或扭伤脚踝的可能性是很小的,不能以此来判定一个人是否足够健康;选项D更适合用于形容喝醉酒的人的走路姿势,与原文测试健康的方法关系不大。
