单选题One of the youngest independent countries in the Western Hemisphere, Trinidad and Tobago, became a nation on August 31, 1962. For a long time this nation has attracted tourists——it is the home of calypso music and limbo dancing——and in recent years its healthy economy has attracted investors as well. Trinidad and Tobago is a single country composed of two islands.. Trinidad, with the majority of the country's 900,000 inhabitants, is a rectangle of roughly fifty by forty miles. Tobago, nineteen miles to the north, is smaller and has a population of about 35,000. Situated at the end of the long chain of Windward and Leeward Islands, Trinidad is at one point only seven miles off the coast of Venezuela. Its geology, flora, and fauna are similar to those of the South American mainland. Like Venezuela, the backbone of Trinidad and Tobago's economy is petroleum and its first colonists were Spaniards. Three mountain ranges, with summits of up to 3,000 feet, cross Trinidad from east to west, while Tobago is a relatively flat coral island, rimmed with fine beaches. The broad plains between Trinidad's mountain ranges are dominated by vast fields of sugar cane that present a symmetrical green pattern when seen from the air. A closer inspection reveals the coconut plantations along the coast and the profusion of brilliant red and yellow flowers of various species that are found all over the island. Houses on both islands tend to be light-colored, with an open style of architecture, in many cases with open space under the entire dwelling. Port-of-Spain, the capital, is a bustling modern city where the pulse of the people reflects Britist, Spanish, and East Indian influences.

单选题Passages 2 To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun. Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, was back in the eleventh century B.C. We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those in high offices. In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against rain were the ancient Romans. During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. ByI680, the umbrella appeared in France and later on in England. By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that women's umbrellas began to be made in a whole variety of colors.

单选题The potential of computers for increasing the control of organizations or society over their members and for invading the privacy of those members has caused considerable concern. The privacy issue has been raised most insistently with respect to the creation and maintenance of data files that assemble information about persons from a multitude of sources. Files of this kind would be highly valuable for many kinds of economic and social research, but they are bought at too high a price if they endanger human freedom or seriously enhance their opportunities of blackmailers. While such dangers should not be ignored, it should be noted that the lack of comprehensive data files has never before been the limiting barrier to the suppression of human freedom. Making the computer the villain in the invasion of privacy or encroachment on civil liberties simply divers attention from the real dangers. Computer data bank files can and must be given the highest degree of protection from abuse. But we must be careful also, that we do not employ such crude methods of protection as to deprive our society of important data it needs to understand its down social processes and to analyze its problems. Perhaps the most important question of all about the computer is what it has come and will do to man"s view of himself and his place in the universe. The most heated attacks on the computer are not focused on its possible economic effects, its presumed destruction of job satisfaction, or its threat to privacy and liberty, but upon the claim that it causes people to be viewed, and to view themselves, as machines. What the computer and progress in artificial intelligence challenge are an ethic that rests on man"s apartness from the rest of nature. An alternative ethic, of course, views man as a part of nature, governed by nature law, subject to the forces of gravity and the demands of his body. The debate about artificial intelligence and the simulation of mean"s thinking is, in considerable part, a confrontation of these two views of man"s place in the universe.
