8、nts were burned to death.Read and ExploreTask One Discovering the Main Ideas1 Answer the following questions with the information contained inText A.1) Why does the author describe Charles Winget and his wife in the first paragraph?Because she intends to show that peoples bodies operate at different
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
15、 in the evening.8) What tips for sleep problems are offered in the text?Three tips are offered.

16、 to resume your normal cycle. And the third tip is that we should beware of sleeping pills, as most sleeping pills wont work for periods longer than two weeks and there is real danger of drug accumulation in the blood.2 Text A can be divided into four parts with the paragraph number(s)of each part p
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.

22、ms function on an approximately 25-hour cycle. (Para. 4)Many people believe that our systems work at the same rate all throughout the day, but it is not true.3. Of course, individual variations make all the differenc. e(Para. 11)Different people may show different patterns of temperature change, and
23、 such differences reflect differences in their circadian rhythms.4. “All the subjects lost weight eating breakfa,s”tstates Sothern.“Those who ate dinner either maintained or gained weig.h”t(Para. 14)Sothern, a chronobiologist who personally did the research and whose words are to be taken seriously,
