associated with a lack of particular vitamins.

Questions 6 to 10 are based on the same passage or dialog. Do you find getting up in the morning so difficult that it's painful? This might be called laziness, but Dr. Kleitman has a new
explanation. He has proved that everyone has a daily energy cycle. During the hours when you labor through your work you may say that you're \energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon (午前). For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (独白) as: \explanation to the trouble is that John is at his
temperature-and-energy peak in the evening. Much family quarreling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract (阻碍) your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point.
When should people take vitamins? A. When wanting to be healthy.
