问题                     Alleviate the Bad Reaction of Flying Jet Lag
    With the global economy now taking more executives to far-away places like Beijing and Mumbai.jet lag is becoming a bigger problem, leading sleep researchers to work harder than ever to find suitable remedies.
    Trips to the other side of the globe make adjusting a traveler’s body clock a more lasting process. Jet-lag experts say they believe it takes one day for each time zone away from home,up to a maximum of six or seven days, to get fully in sync with local time.
    There is no easy remedy. One problem in developing solutions is all the variation in travelers’ ability to handle jet lag. Sleep researchers have found that people who have dealt with sleep loss over long periods—on night shifts, for example—can tolerate jet lag better than most. And older travelers also tend to get harder hit than the young by jet lag. About eight million corporate travelers made overseas trips last year, most of whom were flying to Europe or the Pacific area, throwing their body clocks off kilter and the effects are considered greater going East than West.
    Using a combination of nap and caffeine is better than using them separately, if you can believe it. It takes 15 to 30 minutes for caffeine to kick in. So you do the two together. All it takes is a cup of coffee—not even a pill. By the time the caffeine is working,your nap is over.
    Sleep experts are also working with professional and amateur athletes who, of course, change time zones to play "away" games or perform at international meets. A proper amount of sleep can boost all athlete’s performance as much as 30 percent. They are broadening their research to include the disconnection between flying fatigue and work patterns called "journey management". For example, when companies bring together staff from all over the world for a project,the experts will help coordinate the trips to help make sure everyone is productive when they arrive.
    Jet lag may be largely sleep interruption, but it’s really a complex mixture of being out of sync with your normal pattern of behavior, plus other factors, even including airline food. If you’re going to be abroad for only a few days, why fool around with so many solutions? If you keep resetting your body clock, you’ll end up confusing your feelings.
Which of the following statements is true according to Para. 3?
选项 A、Traveler’s different ability contributes to finding solutions to jet lag.
B、Longer trips make it more difficult to adjust to the changes of time zone.
C、The older the travelers are, the worse the effect of jet lag.
D、Travelers going to Mumbai from America experience no jet lag.
答案C
解析 事实细节题。由题干定位到第三段可知，时差反应是一个影响日益加剧的问题，而不同人群对时差的不同适应能力也使得这个问题更难找到合适的解决方法。但是研究发现，用来适应时差改变的时间越充分，人们对时差的反应就越小；年纪越大，对时差的反应也越强烈；同时，向东航行带来的时差反应比向西航行要严重。故[C]“旅行者年纪越大，时差感反应的作用就越大”与文章意思相符。[A]“旅行者对时差感的不同适应能力有助于找出解决问题的方案”，与原文意思刚好相反，故排除；[B]“较长时间的旅行使人们更难适应时差的改变”，这也与原文意思相反，故排除；[D]“从美国飞往孟买的旅客没有时差感反应”，与本段最后一句意思不符。美国飞往孟买是向东飞行，这不仅会引起时差反应，还会比较强烈，故排除。
