问题     With the tiny screen bouncing around in front of us, tinny sound quality and frequent interruptions, watching a movie during a flight is hardly an immersive experience. Yet, frequent fliers may have found themselves—or at least witnessed others—welling up at the most innocuous of films while on a long airline journey. Even lighthearted comedies such as Bee Movie, Bridesmaids and The Simpsons can trigger the water works in passengers who would normally remain dry-eyed if watching these on the ground. One major airline has gone as far as issuing " emotional health warnings" before inflight entertainment that might upset its customers.
    "There hasn’t been much research done on this in the past as for healthy people these do not pose much of a problem," says Jochen Hinkelbein, president of the German Society of Aerospace Medicine and assistant medical director for emergency medicine at the University of Cologne. " But as air travel has become cheaper and more popular, older and less fit people are travelling by air. This is leading to more interest in the field. " Hinkelbein is one of the researchers who are now examining how the conditions we experience on flights can affect the human body and mind.
    There can be no doubt that aircraft cabins are peculiar places for humans to be. They are a weird environment where the air pressure is similar to that atop an 8,00oft-high (2. 4km) mountain. The humidity is lower than in some of the world’s driest deserts while the air pumped into the cabin is cooled as low as 10℃ (50F) to whisk away the excess heat generated by all the bodies and electronics onboard. The reduced air pressure on airline flights can reduce the amount of oxygen in passengers’ blood between 6 and 25%, a drop that in hospital would lead many doctors to administer supplementary oxygen. For healthy passengers, this shouldn’t pose many issues, although in the elderly and people with breathing difficulties, the impact can be higher.
    For those who are already nervous fliers, there is perhaps some more bad news. "Anxiety levels can increase with hypoxia," explains Valerie Martindale, president of the Aerospace Medical Association at King’s College London. Anxiety is not the only aspect of mood that can be affected by flying. A number of studies has shown spending time at altitude can increase negative emotions like tension, make people less friendly, decrease their energy levels and affect their ability to deal with stress.
    Then there is also research showing altitude can also make people feel happier. But Stephen Groening, a professor of cinema and media at the University of Washington, believes this happiness may also manifest itself as tears. The boredom on a flight and relief given by an inflight movie, combined with the privacy of the small screen and headphones used to watch one, could lead to tears of joy, not sadness, he says. "The configuration of inflight entertainment apparatus produce an affect of intimacy that might lead to heightened emotional responses," says Groening. " Crying on airplanes actually consists of tears of relief.
Aircraft cabins are peculiar places for humans to be for the following reasons EXCEPT that ________.
选项 A、air pressure decreases with growing height
B、the level of oxygen in cabin is fatal to passengers
C、the amount of moisture in the air is inadequate
D、the temperature has to be adjusted to the suitable level
答案B
解析 根据题干关键词peculiar places定位到第三段。第三段主要提到了飞机机舱对人类来说是一个特殊的地方并且给出原因：
(1)飞行时机舱的气压与8 000英尺 (2 400米) 高的山顶的气压相当，气压很低；
(2)机舱的湿度很低，非常干燥；
(3)机舱的温度需要调节以达到适宜的程度；
(4)乘客血液中的氧气含量下降。
[A][C][D]均符合。文中提到，乘客血液中的氧气含量下降对健康的乘客来说，这不会带来太多问题，但对老年人和呼吸困难的人来说，影响可能会更大，并不是说机舱的氧气水平对乘客是致命的，所以选[B]。
