Task One Discovering the Main Ideas
1 Answer the following questions with the information contained in Text A.
1) Why does the author describe Charles Winget and his wife in the first paragraph?
Because she intends to show that people’s bodies operate at different speeds.
2) How would behavioral scientists explain the differences between Charles Winget and his wife?
Behavioral scientists would say that such differences were caused by personal eccentricities or early conditioning.
3) What are ―circadian rhythms‖ according to Franz Halberg?
According to Franz Halberg, circadian rhythms are the regular daily patterns of our body. That is, our systems work on an approximately 25-hour cycle. Sometimes our body speeds up, and sometimes it slows down. It achieves peak efficiency for only a limited time each day.
4) How does the study of chronobiology benefit people in general?
Chronobiology tells people how to coordinate their activities with their biological capacities so that they can achieve their best with the least effort.
5) What approach has been developed to help a person recognize his body’s patterns?
Winget and his associates have developed a simple approach. It is to record 6 readings of a person’s temperature all throughout the day and put the readings on graph paper. The rising or falling patterns of the temperature can be recognized as his body’s patterns.
6) How should we arrange our mental and physical work according to the author?
Physical work can be best done when our rhythms are at their peak. In most people, this peak lasts about four hours. For mental activities, the timetable is more complicated. Precision tasks such as mathematical work are best tackled when your temperature is on the rise. For most people, this is at 8 or 9 a.m. By contrast, reading and reflection are better done between 2 and 4 p.m., which is the time when body temperature usually begins to fall.
