参考答案: The Loss of Traditional Culture
If action is not taken, a nation’s traditional culture is increasingly lost. We do know the cultural disorders are serious and no family, business, community or country is immune to this chaos of information explosion. Virtually everyone will see some type of disruption—only the scope and impact are in question.
Some, in countries where much cultural disorder repair work has already been done, may only see a harmless service warning light come on in their car. Others in less developed areas could be done without sustained food, water, telecommunications or electricity for hours, days, weeks or months. It is in everyone’s interest, around the world, to avoid serious or long-term disruptions that could effect the global economy, rather than retain traditional culture of a nation.
We see that computers and automated systems can do so much, and come to rely on them for the most basic service. For instance, the Chinese water paintings and brushing-pen handwritings have given way to computer on-line designs. Most of us have probably never thought about how a computer cannot think on its own like a human and what that means. Many computerized products and automated office systems are booming instead of Chinese traditional ways of life.
In my belief, cultural disorders know no national or political boundaries. Every country will be effected in some way. Most thoughtful people should sit around thinking not only about how or where their electricity, water and other basic supplies come from, but also about how or when they should take counter-measures to maintain a nation’s traditions of varied culture. Some measure must be carried out to maintain our own systems of traditional culture because, you know, no computers are intelligent enough to know what the traditional spirits of Chinese culture stand for.
