- Plants and Mankind Botany, the study of plants, occupies a peculiar position in the history of human knowledge. We don’t know what our Stone Age ancestors knew about plants, but from what we can observe of preindustrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of people, not only for food, but also for clothing, weapons, tools, dyes, medicines, shehers, and many other purposes. Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each. To them botany has no name and is probably not even recognized as a special branch of "knowledge" at all. Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fall to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away. People can not survive without plants.
- More Than 8 Hours Sleep Too Much of a Good Thing 1. Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2. Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night’s sleep than 8-hour sleepers. 3. These findings, which DL Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night’s rest may not need to set aside more than 8 hours a night. He added that "it might be a good idea" for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4. Previous studies have shown the potential dangers of chronic shortages of sleep—for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5. For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having fatigue interfere with day-to-day functioning. 6. Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bed. "It stands to reason that if a person spends too long a time in bed, then they’ll spend a higher percentage of time awake," he said. A. Kripke’s Research Tool B.

- Man of Few Words Everyone chases success, but not all of us want to be famous. South African writer John Maxwell Coetzee is 1 for keeping himself to himself. When the 63-year-old was named the 2003 Nobel Prize winner for literature earlier this month, reporters were warned that they would find him "particularly difficult to 2 ". Coetzee lives in Australia but spends part of the year teaching at the University of Chicago. He seemed 3 by the news he won the $1.3 million prize. "It came as a complete surprise. I wasn’t even aware they were due to make the announcement," he said. His 4 of privacy led to doubts as to whether Coetzee will attend the prize-giving in Stockholm, Sweden, on December 10. But despite being described as 5 to track down, we critics agree that his writing is easy to get to know. Born in Cape Town, South Africa, to all English-speaking family, Coetzee 6 his breakthrough in 1980 with the novel Waiting for the Barbarians. He 7 his place among the world’s leading writers with two Booker prize victories, Britain’s highest honour for novels. He first 8 in 1983 for the Life and Times of Michael K and his second title came in 1999 for Disgrace. A major theme in his work is South Africa’s former apartheid system, which divided whites from blacks. 9 with the problems of violence, crime and racial division that still exist in the country, his books have enabled ordinary people to understand apartheid 10 within. "I have always been more interested in the past than the future," he said in a rare interview. "The past 11 its shadow over the present. I hope I have made one or two people think 12 about whether they want to forget the past completely." In fact this purity in his writing seems to be 13 in his personal life. Coetzee is a vegetarian, a cyclist rather than a motorist and doesn’t drink alcohol. But what he has 14 to literature, culture and the people of South Africa is far greater than the things he has given up. "In looking at weakness and failure in life," the Nobel prize judging panel said, "Coetzee’s work 15 the divine spark in man."
