问题      Air travel is such an everyday experience these days that we are not surprised when we read about a politician having talks with the Japanese Prime Minister one day, attending a conference in Australia the following morning and having to be off at midday to sign a trade agreement in Hong Kong. But frequent long-distance flying can be so tiring that the traveler begins to feel his brain is in one country, his digestion in another and his powers of concentration nowhere--in short, he hardly knows where he is.
     The fatigue we normally experience after a long journey will become even more acute when we fly from east to west or vice versa because we cross time zones. Air travel is so quick nowadays that we can leave London after breakfast and be in New York in eight hours, yet what really disturbs us most is that when we arrive it is only lunch time when we have already had lunch on the plane and are expecting dinner.
      Doctors say that since air travellers are in no conditions to work after crossing a number of time zones, they should go straight to bed on arrival. Airline pilots, however, often live by their own watches, ignoring local time, and have breakfast at midnight if necessary.
      Businessmen who go on long-distance flights, however, are usually proud of having been chosen because it adds to their position in the firm. They are lucky if the boss is clever enough to insist on their taking the doctor’s advice and resting for a day before work. Sometimes the managing director is such an energetic person that he expects everyone to be as fit as he is. As he has never felt any ill effects after flying himself, the schedule he lays down is so tight that the employee is too exhausted to carry it out satisfactorily. He must either go straight to an important meeting as soon as his plane touches down or else return as soon as the meeting is over to his boss. Managers of this type often do not realize how disastrous this policy may be for the man’s health and the company’s reputation.
Which of the following is NOT affected by crossing time zones?
选项 A、Meal patterns.
B、Sleep.
C、Powers of concentration.
D、Schedule.
答案D
解析 参见第一段最后一句。
