    As a physician who travels quite a lot, I spend a lot of time on planes listening for that dreaded "Is there a doctor on board?" announcement. I’ve been【C1】______ only once—for a woman who had merely fainted. But the【C2】______ made me quite curious about how often this kind of thing happens. I wondered what I would do if【C3】______ with a real midair medical emergency—without access to a hospital staff and the usual emergency equipment. So【C4】______ the New England Journal of Medicine last week published a study about in-flight medical events, I read it with interest.
    The study estimated that there are an average of 30 in-flight medical emergencies on U.S. flights every day. Most of them are not【C5】______; fainting and dizziness are the most frequent complaints.
    But 13% of them—roughly four a day—are serious enough to【C6】______ a pilot to change course.
    The most common of the serious emergencies【C7】______ heart trouble, strokes, and difficulty breathing.
    Let’s face it: plane rides are【C8】______. For starters, cabin pressures at high altitudes are set at roughly what they would be if you lived at 5,000 to 8,000 feet above sea level. Most people can tolerate these pressures pretty【C9】______, but passengers with heart disease may experience chest pains as result of the reduced amount of oxygen flowing through their blood. Another common inflight problem is deep venous thrombosis—the so-called economy class syndrome. Whatever happens, don’t panic. Things are getting better on the in-flight-emergency front. Thanks to more recent legislation,【C10】______ with at least one attendant are starting to install emergency medical kits to treat heart attacks.
【C8】
选项
答案I
解析 由空格前的are，可知空格处应填入形容词或分词。本句为本段的主题句。下文列举的cabin pressures“机舱压力”和the so-called economy class syndrome“经济舱综合征”都是为了说明坐飞机是怎样的一番体验，词库中的stressful“有压力的”符合语义。
