[简答题] One summer my wife Chris and I were invited by friends to row down the Colorado River in a boat. Our expedition included many highly successful people-the kind who have staffs to take care of life’’s daily work. But in the wilder rapids, all of us naturally set aside any pretenses and put out backs into very stroke to keep the boat from tumbling over. At each night’’s encampment, we all hauled supplies and cleaned dishes. After only two days in the river, people accustomed to being spoiled and indulged had become a team, working together to cope with the unpredictable twists and turns of the river. I believe that in life-as well as on boat trips-teamwork will make all our journeys successful ones. The rhythms of teamwork have been the rhythms of my life. I played basketball alongside famous players, and the team I now coach, the New York Knicks, has recovered from years of adversity to become a major contender in the 1990s. I’’m persuaded that teamwork is the key to makin
[单项选择] The Real Death Of Print Vishwas Chavan travels a lot. As an informatician, he collects data on what types of animal live where in India to enter into a biodiversity database. Yet the specimens he hunts for have neither fur nor feathers, but yellowing pages and ageing dust-jackets. Much of the information Chavan seeks is in old, out of-print tomes that are scattered around the world; about 2,500 of the 7,000 books he has unearthed were written in the first half of the nineteenth century. To find them, Chavan has spent years trailing around libraries. He dreams of the day when books such as these are scanned and made available as digital files on the Internet. Chavan and other digitization visionaries paint a future in which books no longer gather dust on shelves, but exist as interconnected nodes in a vast web of stored literature, all accessible at the click of a mouse. So instead of hunting for specific books, scholars could search for

[单项选择] Whether the eyes are "the windows of the soul" is debatable; that they are intensely important in interpersonal communication is a fact. During the first two months of a baby’’s life, the stimulus that produces a smile is a pair of eyes. The eyes need not be real: a mask with two dots will produce a smile. Significantly, a real human face with eyes covered will not motivate a smile, nor will the sight of only one eye when the face is presented in profile. This attraction to eyes as opposed to the nose or mouth continues as the baby matures. In one study, when American four-year-olds were asked to draw people, 75 percent of them drew people with mouths, but 99 percent of them drew people with eyes. In Japan, however, where babies are carried on their mother’’s back, infants do not acquire as much attachment to eyes as they do in other cultures. As a result, Japanese adults make little use of the face either to encode (把......编码) or decode (理解) meaning. In fact, Argyle reveals that t
A. of extreme importance in expressing feelings and exchanging ideas
B. something through which one can see a person’’s inner world
C. of considerable significance in making conversations interesting
D. something the value of which is largely a matter of long debate
[单项选择] To fight against computer crimes, a computer system needs a sure way of identifying its right users and rejecting those who are not entitled to use it. The identification system should be quick, simple, and convenient. At present, signatures are widely used to identify credit card holders, but it takes an expert to detect a good forgery. Sometimes even a human expert is fooled, and there is no reason to believe that a computer could do any better. Photographs are also sometimes used for identification. But, people find it inconvenient to stop by a credit-card company and to be photographed. Companies might lose business if they made the pictures under absolute requirement. Also, photographs are less useful these days, when people frequently change their appearance by changing the way they wear their hair. Finally, computer programs for analyzing photographs are still highly experimental. Cash-drawing systems often use two identification numbers: One is recorded on a
A. signatures
B. photographs
C. fingerprints
D. magnetic stripes
