填空题 Many artists late in the last century were in search of a means to express their individuality. Modem dance was one of the ways some of these people sought to free their creative spirit. At the beginning there was no exacting technique, no foundation from which to build. In later years, trial, error, and genius founded the techniques and the principles of the movement. Eventually, innovators even drew from what they considered the dread ballet, but first they had to discard all that was academic so that the new could be discovered. The beginnings of modem dance were happening before Isadora Duncan, but she was the first person to bring the new dance to general audiences and see it accepted and acclaimed. Her search for a natural movement form sent her to nature. She believed movement should be as natural as the swaying of the trees and the rolling waves of the sea, and should be in harmony with the movements of the Earth. Her great contributions are in three areas. First, she began the expansion of the kinds of movements that could be used in dance. Before Duncan danced, ballet was the only type of dance performed in concert. In the ballet the feet and legs were emphasized, with virtuosity (精湛技巧) shown by complicated movements. Duncan performed dance by using all her body in the freest possible way. Her dance stemmed from her soul and spirit. She was one of the pioneers who broke tradition so others might be able to develop the art. Her second contribution lies in dance costume. She discarded ballet shoes and stiff costumes. These were replaced with bare feet, and unbound hair. She believed in the natural body being allowed to move freely, and her dress displayed this ideal. Her third contribution was in the use of music. In her performances she used the symphonies of great masters, including Beethoven and Wagner, which was not the usual custom. She was as exciting and eccentric (异乎寻常的) in her personal life as in her dance.

填空题There are more than 300 millions of us in the United States, and sometimes it seems like we're all friends on Facebook. But the sad truth is that Americans are lonelier than ever. Between 1985 and 2004, the number of people who said there was no one with whom they discussed important matters tripled, to 25 percent, according to Duke University researchers. Unfortunately, as a new study linking women to increased risk of heart disease shows, all this loneliness can be detrimental to our health. The bad news doesn't just affect women. Social isolation in all adults has been linked to a series of physical and mental ailments, including sleep disorders, high blood pressure, and an increased risk of depression and suicide. How lonely you feel today actually predicts how well you'll sleep tonight and how depressed you'll feel a year from now, says John T. Cacioppo, a neuroscientist at the university of Chicago and coauthor of Loneliness: Human Nature and the Need for Social Connection. Studies have shown that loneliness can cause stress levels to rise and can weaken the immune system. Lonely people also tend to have less healthy lifestyles, drinking more alcohol, eating more fattening food, and exercising less than those who are not lonely. Though more Americans than ever are living alone (25 percent of U.S. households, up from 7 percent in 1940), the connection between single-living and loneliness is in fact quite weak. "Some of the most profound loneliness can happen when other people are present," says Harry Reis, professor of psychology at the University of Rochester. Take college freshmen: even though they're surrounded by people almost all the time, many feel incredibly isolated during the first quarter of the school year with their friends and family members far away, Cacioppo says. Studies have shown that bow lonely freshmen will feel can be predicted by how many miles they are from home. By the second quarter, however, most freshmen have found social replacements for their high-school friends. Unfortunately, as we age, it becomes more difficult to recreate those social relationships. And that can be a big problem as America becomes a more transient society, with and increasing number of Americans who say that they're willing to move away from home for a job. Loneliness can be relative: it has been defined as an aversive(反感的) emotional response to a perceived discrepancy between a person's desired levels of social interaction and the contact they're actually receiving. People tend to measure themselves against others, feeling particularly alone in communities where social connection is the norm. That's why collectivist cultures, like those in Southern Europe, have higher levels of loneliness than individualist cultures, Cacioppo says. For the same reason, isolated individuals feel most acutely alone on holidays like Christmas Eve or Thanksgiving, when most people are surrounded by family and friends.

填空题Sixteen years ago, Eileen Doyle's husband, an engineer, took his four children up for an early morning cup of tea, packed a small case and was never seen or heard of again. Eileen was astonished and in a state of despair. They had been a happy family and, as far as she knew, there had been nothing wrong with their marriage. Every day of the year, a small group of men and women quietly pack a few belongings and without so much as a note or a good-bye close the front door for the last time, leaving their debts, their worries and their confused families behind them. Last year, more than 1200 men and nearly as many women were reported missing from home—the highest in 15 years. Many did return home within a year, but others rejected the past completely and axe now living a new life somewhere under a different identity. To those left behind this form of desertion is a terrible blow to their pride and self-confidence. Even the finality of death might be preferable. At least it does not imply rejection or failure. Worse than that, people can be left with an unfinished marriage, not knowing whether they will have to wait seven years before they axe free to start a fresh life. Clinical psychologist Paul Brown believes most departures of this kind to be well planned rather than impulsive. "It's typical of the kind of personality which seems able to ignore other people's pain and difficulties. Running away, like killing yourself, is a highly aggressive act. By creating an absence the people left behind feel guilty, upset and empty. " The Salvation Army's Investigation Department has a 70 percent success rate in tracking missing people down. According to Lt. Co. Bramwell Pratt, head of the department, men and women run away for very different reasons though lack of communication is often the biggest motive, "The things that disturb a man's personality are problems like being tied up in debt or serious worries about work. And some women make impossible demands on their husbands. Women usually leave for more obvious reasons but fear is at the root of it. Men are more often prepared to give their marriage another try than women, but we are aware that, for some wives, it would be a total impossibility to return after the way they've been treated. /
