Most people who travel long distances complain of jetlag. Jetlag makes business travelers less productive and more prone to making mistakes. It is actually caused by【C1】________ of your "body clock"—a small cluster of brain cells that controls the timing of biological functions. The body clock is designed for a【C2】________ rhythm of daylight and darkness, so that it is thrown out of balance when it encounters daylight and darkness at the wrong times in a new time zone.
The symptoms of jetlag often persist for days【C3】________ the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is【C4】________ that is based on proven extensive pioneering scientific research.
Dr. Martin Moore-Ede has【C5】________ a practical strategy to adjust the body clock much sooner to the new time zone through controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates most of the discomfort of jetlag. A successful time zone shift depends on knowing the exact time to either【C6】________ or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule for light exposure depends a great deal on【C7】________ travel plans. Data on a specific flight itinerary and the individual’s sleep pattern are used to produce a Trip Guide with 【C8】________ on exactly when to be exposed to bright light. When the Trip Guide calls for bright light you should spend time outdoors if possible. If it is【C9】________ outside, or the weather is bad, or you are on an aeroplane, you can use a special light device to provide the necessary light【C10】________ for a range of activities such as reading, watching TV or working.
【C9】
选项
答案
B
解析
空格所在的从句与下文的or…is bad并列,故空格处应填入与bad词性相同的形容词。从下文的to provide the necessary light“提供必要的光照”可推测此处表示光线不好,备选形容词中的dark“黑暗的”符合语境要求。故选B。
