    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 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.

选项
答案 O
解析 空格前的is提示空格处要么填入形容词作表语，要么填入动词分词。此处的句意为“应对时差反应的方法现在——了”。下一段描述Martin Moore-Ede博士的策略时用了practical“实用的”，这说明该方法现在是可用的，词库中的available“可利用的”符合要求。practical“实用的”和agreeable“令人愉快的”是不能等同的，故排除F。
