Health is the most enjoyed, but the least envied. — Charles Caleb Colton Interpretation:By using four superlatives, Colton points out the paradox of people’s attitudes towards money and health. We tend to envy those who possess more money, but those who possess more money may not feel happy and satisfied. In contrast, we seldom feel envy for those who enjoy good health, for good health can only be enjoyed by those who possess it.

Rockefeller, Jr Interpretation:As a great philanthropist (慈 善 家 ), Rockefeller Jr. believes that giving and caring for others will bring you a healthy life. What you offer to others may not necessarily be money or material comforts. Spiritual care such as encouragement, sympathy and understanding is equally good and can also serve as the key to a healthy life.

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 these regular patterns “circadian rhythms.” 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. Taking the given approach to figure out our body’s patterns, we can then take advantage of chronobiology techniques to improve our health and productivity in such aspects of life as our daily work, dieting, taking medicine and sleeping. It is important to keep regularity in all aspects of our life and learn to act in synchronization with our body’s natural rhythms. Unit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views28新世纪大学英语系列教材（第二版）综合教程3 Have you ever wondered why some times each day you achieve greater efficiency than other times, why you are aware more keenly of aches and pains, and why it is easier for you to fall asleep?

It is barely 5 a.m., but Winget is raring to go. Meanwhile, his wife pulls up the covers and buries her face under the pillow. “For the past fifteen years,” says Winget, “we’ve hardly ever gotten up together.” 2 The Wingets’ situation is not uncommon. Our bodies operate with the complexity of clocks, and like clocks, we all run at slightly different speeds. Winget is a morning person. His wife is not at her best until after nightfall.

This thinking was challenged in the late 1950s by a theory labeled chronobiology by physician-biologist Franz Halberg. In a Harvard University laboratory, Dr. Halberg found that certain blood cells varied predictably in number, depending on the time of day they weredrawn from the body. The cell count was higher at a given time of day and lower 12 hours later. He also discovered that the same patterns could be detected in heart and metabolic rates and body temperature.Unit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views31新世纪大学英语系列教材（第二版）综合教程3In-Depth4 Halberg’s explanation: instead of performing at a steady, unchanging rate, our systems function on an approximately 25-hour cycle. Sometimes we are accelerating, sometimes slowing down. We achieve peak efficiency for only a limited time each day. Halberg called these regular patterns “circadian rhythms.” 5 Much of the leading work in chronobiology is sponsored today by the National Aeronautics and Space Administration. Charles Winget, a NASA research physiologist and authority on circadian rhythms, says that circadian principles have been applied to astronauts’ work schedules on most of the space-shuttle flights. Unit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views32新世纪大学英语系列教材（第二版）综合教程36 The space-age research has many useful applications here on earth. Chronobiologists can tell you when to eat and still lose weight, what time of day you’re best equipped to handle the toughest challenges, when to go to the dentist with your highest threshold of pain and when to exercise for maximum effect. “It’s a biological law of human efficiency: to achieve your best with the least effort, you have to coordinate the demands of your activities with your biological capacities,” Winget says. In-DepthUnit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views33新世纪大学英语系列教材（第二版）综合教程37 Circadian patterns can be made to work for you. But you must first learn how to recognize them. Winget and his associates have developed the following approach to help you figure out your body’s patterns. 8 Take your temperature one hour after getting up in the morning and then again at four-hour intervals throughout the day. Schedule your last reading as close to bedtime as possible. You should have five readings by the end of the day. 9 Now add your first, third and fifth readings and record this total. Then add your second and fourth readings and subtract this figure from the first total. That number will be an estimate of your body temperature in the middle of the night. Consider it your sixth reading. In-DepthUnit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views34新世纪大学英语系列教材（第二版）综合教程310 Now plot all six readings on graph paper. The variations may seem extremely small — only one-tenth of a degree in some cases — but they are significant. You’ll probably find that your temperature will begin to rise between 3 a. m. and 6 a. m., reaching a peak sometime in the late morning or early afternoon. By evening the readings start to drop. They will steadily decline, reaching their lowest points at around 2 a.m. 11 Of course, individual variations make all the difference. At what hour is your body temperature on the rise? When does it reach its highest point? Its lowest? Once you have familiarized yourself with your patterns, you can take advantage of chronobiology techniques to improve your health and productivity. In-DepthUnit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views35新世纪大学英语系列教材（第二版）综合教程312 We do our best physical work when our rhythms are at their peak. In most people, this peak lasts about four hours. Schedule your most demanding activities when your temperature is highest. 13 For mental activities, the timetable is more complicated. Precision tasks, such as mathematical work, are best tackled whenIn-Depthyour temperature is on the rise. For most people, this is at 8 or 9 a.m. By contrast, reading and reflection are better pursued between 2 and 4 p.m., the time when body temperature usually begins to fall.Unit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views36新世纪大学英语系列教材（第二版）综合教程314 Breakfast should be your largest meal of the day for effective dieting. Calories burn faster one hour after we wake up than they do in the evening. During a six-year research project known as the Army Diet study, Dr. Halberg, chronobiologist Robert Sothern and research associate Erna Halberg monitored the food intake of two groups of men and women. Both ate only one 2000-In-Depthcalorie meal a day, but one group ate their meal at breakfast and the other at dinner. “All the subjects lost weight eating breakfast,” states Sothern. “Those who ate dinner either maintained or gained weight.”Unit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views37新世纪大学英语系列教材（第二版）综合教程315 If foods are processed differently at different times of the day, certainly caffeine, alcohol and medicines will be too. Aspirin compounds, for example, produce the greatest effect in the morning, between 7 and 8. (So does alcohol.) They are least effective between 6 p.m. and midnight. Caffeine has the most impact around 3 in the afternoon. Charles Walker, Dean of the College of Pharmacy at Florida A & M University, explains, “Stimulants are most effective when you are normally active, and sedatives work best when you’re naturally sedate or asleep.” In-DepthUnit 5Read and Explore – Text ADiscovering the Main IdeasIn-Depth StudyVoicing Your Views38新世纪大学英语系列教材（第二版）综合教程316 Knowing your rhythms can also help you overcome sleep problems. Consult your body-temperature chart. Your bedtime should coincide with the point at which your temperature is lowest. This is between 11 p.m. and 2 a.m. for most people. 17 Dr. Michael Thorpy of the Sleep-Wake Disorders Center at Montefiore Medical Center in New York City offers other circadian sleep tips: go to bed at the same time every night and get up at the same time every morning, even on weekends. “Irregularity in sleep and waking times is the greatest cause of sleep problems,” Dr. Thorpy says. The best way to recover from a bad night’s sleep is simply to resume your normal cycle. Beware of sleeping pills. “Most sleeping pills won’t work for periods longer than two weeks,” warns Dr. Thorpy. And there is real danger of drug accumulation in the blood.

Increasing stress, loneliness and a lack of medical support for depression are thought to have contributed to an annual suicide toll that is estimated at 250,000 people a year. According to China Daily, an additional 2.5 million to 3.5 million make unsuccessful attempts to kill themselves each year. (by Jonathan Watts, July 26, 2005) Unit 5Enhance Your Language AwarenessUseful ExpressionsGrammar in ContextTheme-Related Writing70新世纪大学英语系列教材（第二版）综合教程3  Why do the Young Adults Kill Themselves? Young adults are in the prime of their lives and are supposed to pursue their dreams and enjoy themselves. Yet it was reported in the Guardian that suicide is the main cause of death among young adults in China. Why have so many young people ended their lives? Three factors are thought to account for the high suicide rate: increasing stress, loneliness and a lack of medical support for depression. The most pressing one, I think, is stress. Take my college life forwritingSampleWritingUnit 5Enhance Your Language AwarenessUseful ExpressionsGrammar in ContextTheme-Related Writing71新世纪大学英语系列教材（第二版）综合教程3example. From the first day I entered the university, I have been living under pressure. I used to worry that I could not quite fit into the campus life; I also feared that I might not catch up with my classmates in my studies or could not live up to my parents’ expectations. Now I am deeply concerned about whether I can find a desirable job after graduation. Endless pressures give rise to stress. Loneliness is another problem. Many young people find they just feel helpless when they are suffering intolerable sadness or frustration. Suicide is a great tragedy, especially for the young. If we can find ways to relieve them of their stress and offer timely help, we may save many young lives. writingSampleWritingThank You!。
