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 most probable meaning of the word "kilter" (Line 12, Para. 3)?
选项 A、A killer who will kill others because of money.
B、A good condition in which a kind of balance is kept.
C、A place where people can change their body clocks.
D、A place in Europe where most people want to go.
答案B
解析 语义理解题。由题干定位到第三段最后一句可知，在过去的一年中有大约八百万旅行者飞往海外，而本文主要讲的是海外-旅行给人造成的时差感反应，由此推断，他们的生物钟肯定受到了影响。另外依据词组中。仟有“脱离，偏离”的意思，kilter应是“平衡，正常状态”的意思，即生物钟失去了平衡。[B]“保持平衡的良好状态”与文章意思相符。[A]“因为钱财而杀害别人的杀手”，这是根据词形设置的干扰项，文中根本未提及，故排除．[C]“能够改变生物钟的地方”、[D]“人们都想去的欧洲的某个地方”，均不符合原文意思，故排除。
