问题      Most people who travel long distances complain of jetlag (喷气飞行时差反应). Jetlag makes business travelers less productive and more prone  【21】______   making mistakes. It is actually caused by  【22】______   of your "body clock"—a small cluster of brain cells that controls the timing of biological  【23】______   . The body clock is designed for a  【24】______   rhythm of daylight and darkness, so that it is thrown out of balance when it  【25】______   daylight and darkness at the "wrong" times in a new time zone. The  【26】______   of jetlag often persist for days  【27】______   the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is  【28】______   that is based on proven  【29】______   pioneering scientific re- search. Dr. Martin Moore-Ere has  【30】______   a practical strategy to adjust the body clock much sooner to the new time zone  【31】______   controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates   【32】______   of the discomfort of jetlag. A successful time zone shift depends on knowing the exact times to either  【33】______   or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule  【34】______   light exposure depends a great deal on  【35】______   travel plans. Data on a specific flight itinerary (旅行路线) and the individual’s sleep  【36】______   are used to produce a Trip Guide with  【37】______   on exactly when to be exposed to bright light. When the Trip Guide calls  【38】______   bright light you should spend time outdoors if possible. If it is dark outside, or the weather is bad,  【39】______   you are on an aero plane, you can use a special light device to provide the necessary light  【40】______   for a range of activities such as reading, watching TV or working.
