Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labour through your work you may say that you're "hot". That's true.
The time of day when you feel most energetic is when your cycle of body temperature is at its peak.
For some people the peak comes during the forenoon. For others it comes in the afternoon or evening.
No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: "Get up,
John! You'll be late for work again!" The possible explanation to the trouble is that John is at his
temperature-and-energy peak in the evening. Much family quarrelling 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 (对抗) 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 (鼓起干劲) and work better at your low
point. Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on
the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for
clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon
and save tasks requiring more energy or concentration for your sharper hours.
B. he refuses to follow his own energy cycle
C. he is not sure when his energy is low

C. overcome his laziness
D. go to bed earlier
B. help you to control your temper early in the day
C. enable you to concentrate on your routine work
D. keep your energy cycle under control all day

Do you have a sore throat, a running nose and a headache? Do you keep coughing and sneezing? If you do, the chances are that you have a cold or perhaps flu---but which one? Although both colds and flu are caused by viruses, they are very different illnesses.
Colds, which usually last about a week, affect the nose most. They commonly cause a running nose and sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.
Flu is a much more serious illness and is caused by different groups of viruses. People with flu usually get all the symptoms(症状) described above. However, they also get a high fever, a dry cough and much worse aching. Fever is one of the characteristic symptoms of the flu for all ages. The symptoms also last much longer. Sometimes they don’t disappear for at least two weeks.
Flu can be a deadly disease. The elderly(年长的), who are weaker and less healthy than most younger people, can die from flu. This is one reason why old people are advised to have a flu injection(预防针) before the start of winter when flu is most common. This injection is inexpensive and definitely(明显地)worth it.
If you have a cold or flu, you must always deal with used tissues(手巾纸) carefully. Don’t leave dirty tissues on your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze! You don’t want to see the small drops of liquids blown(喷) out of your nose and mouth when you sneeze, do you? Disgusting(令人作呕), eh? Now you can understand why it’s a good idea to cover your nose and mouth when you sneeze!
