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.
What can be inferred from Para. 5?
选项 A、Sleep experts only concentrate on professional athletes’ performances.
B、Athletes’ performances can be improved by suitable remedies from sleep experts.
C、Journey management is a long-established job involving in jet lag.
D、Employees of some companies enjoy their far-away journey very much.
答案B
解析 推理判断题。由题干定位到第五段可知，睡眠专家对时差反应的研究可以帮助出远门参加运动会的运动员提高成绩，还可以帮助被从外地召集来的员工在工作中保持高效率。故可以推断出[B]“运动员的成绩可以通过专家们合适的方法来补救”。[A]“睡眠专家只关心专业运动员的成绩”，根据本段第一句可知，专业运动员和业余运动员都是专家研究帮助的对象，故排除；[C]“‘旅行管理’是一门很早以前就出现的研究时差感反应的工作”，根据第一段可知，对于时差反应的研究是近日随着问题的严重性才开始的，并不是存在很久了，故排除；[D]“许多公司的职员都很喜欢长途旅行”，若果真如此，那么睡眠专家们也就不需要研究如何帮他们提高工作效率了，这与原文不符，故排除。
