　　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 61 making mistakes. It is actually cause by 62 of your "body clock"-a small cluster of brain cells that controls the timing of biological 63 . The body clock is designed for a 64 rhythm of daylight and darkness, so that it is thrown out of balance when it 65 day light and darkness at the "wrong" times in a new time zone. The 66 of jetlag often persist for days 67 the internal body clock slowly adjusts to the new time zone.
Now a new anti-jetlag system is 68 that is based on proven 69 pioneering scientific research. Dr. Martin Moore-Ede has 70 a practical strategy to adjust the body clock much sooner to the new time zone 71 controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates 72 of the discomfort of jetlag.
　　A successful time zone shift depends on knowing the exact times to either 73 or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule 74 light exposure depends a great deal on 75 travel plans.
　　Data on a specific flight itinerary(旅行路线) and the individual's sleep 76 are used to produce a Trip Guide with 77 on exactly when to be exposed to bright light.
　　When the Trip Guide calls 78 bright light you should spend time outdoors if possible. If it is dark out-side, or the weather is bad, 79 you are on an aeroplane, you can use a special light device to provide the necessary light 80 for a range of activities such as reading, watching TV or working.

　　Successful safety programs may 45 greatly in the emphasis placed on certain aspects of the program. Some place great emphasis on mechanical guarding. Others stress safe work practices by 46 rules or regulations. 47 others depend on an emotion appeal to the worker. But, there are certain basic ideas that must be used in every program if maximum results are to be obtained.
　　There can be no question about the value of a safety program. From a financial standpoint alone, safety 48 .The fewer the injury 49 , the better the workman's insurance rate. This may mean the difference between operating at 50 or at a loss.
