Louis “Satchmo” Armstrong（1900 ～ 1971）, an African-American musician, is one of the most important figures in the history of jazz. In the 1920s, this trumpeter, singer and bandleader began exploring the boundaries （分界）of jazz technique and style. Masters of jazz today admit their debt to this pioneer.

　　Armstrong’s gift was obvious from the start of his career. His earliest recordings—first with a band led by his former teacher, Joe “King” Oliver, and then with his own band-earned Armstrong international fame for technical originality （独创性）. He freed his playing from the ordinary rhythms of early jazz by creating musical phrases that seemed to oppose the pulse of a song, only to combine them in the place later. His deep and rough voice became as special as his cornet（短号）playing, especially in his scat performances. Scat is a singing style in which meaningless syllables（音节）are repeated without preparation. Armstrong’s scat was among the earliest ever recorded.

　　By 1930, Armstrong had turned to more commercial, less experimental jazz. Some musicians criticized（批评）him for this. But others insisted that the real power of Armstrong’s art lay in its grace and sensitivity, fine qualities of the heart which remained in his music.

　　In the following years, Armstrong traveled around the world as the leading “goodwill ambassador（大使）”of American jazz music. The gentleness and great attraction of “Satchmo” filled his music and made him one of the world’s most beloved performers for over forty years.

It is difficult for parents of nearly every family to teach their children to be responsible （有责任的）for housework, but with one of the following suggestions, you really can get your children to help at home.
　　If you give your children the impression that they can never do anything quite right, then they will regard themselves as unfit or unable persons. Unless children believe they can succeed, they will never become totally independent.
　　My daughter Carla’s fifth - grade teacher made every child in her class feel special. When students received less than a prefect test score, she would point out what they had mastered and declared firmly they could learn what they had missed.
　　You can use the same technique when you evaluate （评价）your child’s work at home. Don’t always scold and give lots of praise instead. Talk about what he has done right, not about what he hasn’t done. If your child completes a difficult task, promise him a Sunday trip or a ball game with Dad.
　　Learning is a process（过程）of trying and failing and trying and succeeding. If you teach your children not to fear a mistake of failure, they will learn faster and achieve success at last.

Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.

　　Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.

　　The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.

In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. equal. Some of them decided to "drop out" of American society and form their own societies. They formed utopian communities, which they called “communes”, where they could follow their philosophy of “do your own thing”. A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller, they built dome-shaped houses from pieces of old cars. Other groups, such as author Ken Kesey’s Merry Pranksters, the followers of San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school houses and traveled around the United States. The Hog Farm became famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin’s followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the group were arrested for growing marijuana.
　　Not all communes believed in the philosophy of “do your own thing”. However, Twin Oaks, a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner’s “conditioning” techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an “archeology”. Soleri believes that people must live closely together so that they will all become one.
