9、 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 personaleccentricities or early conditioning.3) What are “circadian rhythms” according to Franz Halberg?According to Franz Halbe
10、rg, 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
11、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 bodys patterns?Winget and his associates have developed a simple app
12、roach. It is to record 6readings of a persons 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 bodys patterns.6) How should we arrange our mental and physical work according to the author?Physical work
13、can be best done when our rhythms are at their peak. In mostpeople, 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
14、contrast, reading and reflection are better done between 2 and 4 p.m., which is the time when body temperature usually begins to fall.7) What tips does chronobiology offer for effective dieting?Eating breakfast rather than dinner helps to lose weight, because calories burn faster in the morning than

16、 to resume your normal cycle.

17、rovided as follows. Write down the main idea of eachpart.Part Paragraph(s) Main IdeaOne 14 Our bodies operate with the complexity of clocks. Franz Halberg, a physician-biologist, discovered that there is a 25-hour cycle in the body with the body systems running with regular patterns. Halberg called
18、these regular patterns “circadian rhythms.”Two 56 Circadian principles have already been used to schedule astronauts work and it is expected that the work in chronobiology will be applied to increasing our efficiency in daily activities.Three 717 Taking the given approach to figure out our bodys pat
19、terns, we can then take advantage of chronobiology techniques to improve our healthand productivity in such aspects of life as our daily work, dieting, taking medicine and sleeping.Four 18 It is important to keep regularity in all aspects of our life and learn to act in synchronization with our body
20、s natural rhythms.Task Two Reading Between the LinesRead the following sentences carefully and discuss in pairs what theauthor intends to say by the italicised parts.1.
