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 is the solution to jet lag according to Para. 4?
选项 A、Drink a cup of coffee and then go to sleep on the plane.
B、Take a pill which contains caffeine and go to sleep.
C、Try to fall asleep after boarding on the plane.
D、Sleep as long as possible after getting on the plane.
答案A
解析 事实细节题。根据题干定位于第四段，第一句提到：用睡眠和咖啡因相结合的方法能比较好地缓解时差反应。两者结合比单独使用其中一种效果要好些。故[A]“喝一杯咖啡然后睡觉”与文意相符。[B]“吃一片含有咖啡因的药片然后睡觉”，根据本段第四句，根本无需吃药，故排除．[C]“一上飞机就努力睡着”，原文中并未提及，故排除；[D]“飞机上尽可能长时间的睡觉”，这只是需要做的其中一部分，故排除。
