Colds and Age A critical factor that plays a part in susceptibility to colds is age. A study done by the University of ichigan School of Public Health revealed particulars that seem to hold true for the general population. Infants are the most cold ridden group, averaging more than six colds in their first years. Boys have more colds than girls up to age three. After the age...
The Happy door Happiness is like a pebble dropped into a pool to set in motion an ever-widening circle of ripples. As Stevenson has said, being happy is a duty. There is no exact definition of the word happiness. Happy people are happy for all sorts of reasons. The key is not wealth or physical well-being, since we find beggars, invalids and so-called failures, who are extre...

Animals’ Compasses Researchers have found that migrating animals use a variety of inner compasses to help them navigate. Some steer by the position of the Sun. Others navigate by the stars. Some use the Sun as their guide during the day and then switch to star navigation by night. One study shows that the homing pigeon uses the Earth’s magnetic fields as a guide ...
Raising Oysters In the past oysters were raised in much the same way as dirt farmers raised tomatoes – by transplanting them. First, farmers selected the oyster bed, cleared the bottom of old shells and other debris, then scattered clean shells about. Next, they “planted” fertilized oyster eggs, which within two or three weeks hatched into larvae. The larva...

树 我想我永远也不会看到 象一棵树那样优美的诗篇， 树那饥渴的嘴唇紧紧贴住 大地乳汁甘美的胸脯， 它整天仰望着上帝， 举起枝叶繁茂的手臂祈祷， 它那茂密如发的枝叶里 夏天会筑起知更鸟的安乐窝， 雪花飘落在它怀里， 它同雨水亲密无间。 诗歌出自我等愚人之手， 而树却是造化的天工。 乔埃斯·基尔默 (1) prest: pressed的变体，为了与下面一行最后一个词breast押韵而采用。 (2)flowing breast： 相当于b...
Human Life a Poem I think that, from a biological standpoint, human life almost reads like a poem. It has its own rhythm and beat, its internal cycles of growth and decay. It begins with innocent childhood, followed by awkward adolescence trying awkwardly to adapt itself to mature society, with its young passions and follies, its ideals and ambitions; then it reaches a manho...
Movie Music Accustomed though we are to speaking of the films made before 1927 as “silent”, the film has never been, in the full sense of the word, silent.From the very beginning, music was regarded as an indispensable accompaniment; when the Lumiere films were shown at the first public film exhibition in the United States in February 1896, they were accompanied ...
Solitude I find it wholesome to be alone the greater part of the time. To be in company, even with the best, is soon wearisome and dissipating. I love to be alone. I never found the companion that was so companionable as solitude. We are for the most part more lonely when we go abroad among men than when we stay in our chambers. A man thinking or working is always alone, le...
Plankton Scattered through the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They drift about lazily with the currents, providing a basic food for many larger animals. Plankton has been described as the equivalent of the grasses that grow on the dry land continents...
The traditional holidays in our house when I was a child were spent timing elaborate meals around football games. My father tried to make pleasant chitchat and eat as much as he could during halftime. At Christmas he found time to have a cup or two of holiday cheer and do his holly-shaped bow tie1. But he didn’t truly shine until Valentine’s Day. I don’t kn...

A Curious Decision A poor chimney-sweeper, who had not enough money to buy a meal, stopped one hot summer day at noon before an eating-house, and remained regaling his nose with the smell of the victuals. The master of the shop told him several times to go away, but the sweep(1) could not leave the savory smell, though unable to purchase the taste of the food. At last the co...
VTo be or not to be Outside the Bible, these six words are the most famous in all the literature of the world. They were spoken by Hamlet when he was thinking aloud, and they are the most famous words in Shakespeare because Hamlet was speaking not only for himself but also for every thinking man and woman. To be or not to be, to live or not to live, to live richly and abunda...
The Early Settlers in North America The North American frontier changed some of the characteristics of the pioneers of the 1750’s and intensified others.They were, as a group, semiliterate, proud, and stubborn, as dogged in their insistence on their own way of life as pine roots cracking granite to grow.Perhaps their greatest resource was their capacity to endure. They...
Coal-fired Power Plants The invention of the incandescent light bulb by Thomas A. Edison in 1879 created a demand for a cheap, readily available fuel with which to generate large amounts of electric power. Coal seemed to fit the bill, and it fueled the earliest power stations (which were set up at the end of the nineteenth century by Edison himself. As more power plants were...
The Source of Energy A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun’s very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is liberated at the center of the Sun as billions upon billions of nuclei of hydrog...

Bacteria Bacteria are extremely small living things. While we measure our own sizes in inches or centimeters, bacterial size is measured in microns. One micron is a thousandth of a millimeter: a pinhead is about a millimeter across. Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron in diameter. Thus if you enlarged a r...
