问题     Many of us have found ourselves trying to explain to friends and colleagues that, no, business travel isn’t as fun and glamorous as it seems. Finally, there could be proof to back this up. Researchers at the University of Surrey, in Britain, and Linnaeus University, in Sweden, have published a new study highlighting what they call "a darker side of hypermobility. " The researchers warn, "whilst aspects of glamorisation in regard to mobility are omnipresent in our lives, there exists a worrying silence with regard to its darker side.
    The study, which synthesises existing research on the effects of frequent travel, finds three types of consequence: physiological, psychological and emotional, and social. The physiological ones are the most obvious. Jet lag is the suffering travellers know best, although they may not anticipate some of its more terrible, if rarer, potential effects, like speeding ageing or increasing the risk of heart attack and stroke. Then there’s the danger of exposure to germs and radiation -people who fly more than 85,000 miles a year exceed the regulatory limit for exposure to radiation. And finally, of course, business travellers tend to get less exercise and eat less healthily than people who stay in place.
    The psychological and emotional toll of business travel is more abstract, but just as real. Frequent flyers experience "travel disorientation" from changing places and time zones so often. They also suffer mounting stress, given that "time spent travelling will rarely be offset through a reduced workload, and that there may be anxieties associated with work continuing to accumulate whilst away. " Due to the absence from family and friends, "hypermobility is frequently an isolating and lonely experience," the authors write. The accumulated impact can be substantial.
    Finally, there are the social effects. Marriages suffer from the time apart, as does children’s behaviour. What is more, relationships tend to become more unequal, as the partner who stays at home is forced to take on more domestic duties. There’s a gender disparity here, since most business travellers are men. Friendships also fray, as business travellers often " sacrifice local collective activities and instead prioritise their immediate families when returning from trips. "
    Of course, these impacts are comforted by the fact that they fall disproportionately on a segment of the population that is already doing rather well. The "mobile elite" tend to have higher incomes and access to better health care than the population at large.
    These may be problems of the very few people, though, they’re real enough regardless. By all means feel jealous of acquaintances’ Instagram photos of exotic meals and faraway attractions. But harbour a small amount of concern as well.
Which of the following is true according to Paragraph 2?

选项 A、Among the effects of frequent travel, the physiological ones are easiest to deal with.
B、The potential harm of jet lag might be much bigger than many people have thought.
C、More exposure to radiation might lead to faster ageing and bigger risk of heart attack.
D、Business travellers tend to have shorter longevity than others.

答案B

解析 本题是细节题。根据题干定位至第二段。该段第三句指出,飞行时差是旅行者最为熟悉的一种伤害,不过一般的旅行者或许并不知道,飞行时差可能会带来一些尽管并不常见但更为严重的潜在后果,如加速人体衰老或增加患心脏病及中风的风险。可知,飞行时差可能带来的危害要比许多人所认为的更大,故答案选B。A项“在频繁旅行的影响中,生理上的影响最容易处理”属过度推断,第二段第二句只提到“生理上的影响最为明显”,但并不等于最容易处理,故排除;第二段中并未提及辐射也会带来这些危害及商务旅行者会比其他人寿命更短,故排除C项“更多地接触辐射可能会导致更快地衰老和更大的心脏病风险”和D项“商务旅行者往往比其他人寿命更短”。
