单选题选出应填入下面一段英语中______内的正确答案。 Prior to the UML, there was no clear leading (1) language. Users had to choose. from among many similar modeling languages with minor differences in overall (2) power. Most of the modeling languages shared a set of commonly accepted concepts that are expressed slightly differently in various languages. This lack of (3) discouraged new users from entering the OO market and from doing OO modeling, without greatly expanding the power of modeling. Users longed for the industry to it adopt one, or a very few, broadly supported modeling languages suitable for (4) usage. Some vendors were discouraged from entering the OO modeling area because of the need to support many similar, but slightly different, modeling languages. In particular, the supply of add-on tools has been depressed because small vendors cannot afford to support many different formats from many different (5) modeling tools. It is important to the entire OO industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.

单选题Unlike the carefully weighed and planned compositions of Dante, Goethe"s writings always have a sense of immediacy and enthusiasm. He was a constant experimenter with life, with ideas and with forms of writing. For the same reason, his works seldom have the qualities of finish or formal beauty which distinguish the masterpieces of Dante and Virgil. He came to love the beauties of classicism, but it was never an essential part of his make-up. Instead, the urgency of the moment, the spirit of the thing, guided his pen. As a result, nearly all his works have serious flaw of structure, of inconsistencies, of excesses and redundancies and extremities. In a large sense, Goethe represents the fullest development of the romanticism. It has been argued that he should not be so designated because he so clearly matured and outgrew the kind of romanticism exhibited by Wordsworth, Shelley, and Keats. Shelley and Keats died young; Wordsworth lived narrowly and abandoned his early attitudes. In contrast, Goethe lived abundantly and developed his faith in the spirit, his understanding of nature and human nature, and his reliance on feelings as man"s essential motivating force. The result was an all-encompassing vision of reality and a philosophy of life broader and deeper than the partial visions and attitudes of other romanticists. Yet the spirit of youthfulness, the impatience with close reasoning or "logic chopping", and the continued faith in nature remained his to the end, together with an occasional waywardness and impulsiveness and a disregard of artistic or logical propriety, which savor strongly of romantic individualism. Since so many twentieth century thoughts and attitudes are similarly based on the stimulus of the Romantic Movement. Goethe stands as particularly the poet of the modern man as Dante stood for medieval man and as Shakespeare for the man of the Renaissance.

单选题Which of the following inferences CANNOT be made from the information in paragraph one?

单选题 I started a company years ago, and consumed MYM 75,000 a month. Four months aftermy company was set up, I had only a quarter of the starting capital left in the bank. Looking for guidance, I went to talk to my friend, Arthur Walworth about my new venture. "Times of great change always bring out the risk-takers," he said, "and they leave winners and losers. " There was a period when CD-ROM sales had bombed. Investors were fleeing from the field. I didn't turn away from mine entirely, but instead linked it to the Internet. My plan was to offer consumers descriptions of home-design products by using a special software and let them modify the designs. Then we can enable them to get online professional and constructional help to have their houses built, decorated and furnished according to their own choice. To realize my plan I needed investors, so I continued to meet regularly with venture capitalists. One said I had a great idea. But I needed to test it. I was working nonstop-struggling to find the fight way ahead. The pressure was terrible. To get the money from a venture capitalist is going to cost my wife and my children ! It was just at this time that my parents and sisters stepped up. Two hundred thousand dollars is a lot of money to them, but they invested in this crazy son and brother without a moment's hesitation. With their help my company survived and has been prospering ever since.

单选题The biggest danger facing the global airline industry is not the effects of terrorism, war, SARS and economic downturn. It is that these blows, which have helped ground three national flag carriers and force two American airlines into bankruptcy, will divert attention from the inherent weaknesses of aviation, which they have exacerbated. As in the crisis that attended the first Gulf War, many airlines hope that traffic will soon bounce back, and a few catastrophic years will be followed by fuller planes, happier passengers and a return to profitability. Yet the industry's problems are deeper--and older--than the trauma of the past two years implies. As the centenary of the first powered flight approaches in December, the industry it launched is still remarkably primitive. The car industry, created not long after the Wright Brothers made history, is now a global industry dominated by a dozen firms, at least half of which make good profits. Yet commercial aviation consists of 267 international carriers and another 500-plus domestic ones. The world's biggest carrier, American Airlines, has barely 7% of the global market, whereas the world's biggest carmaker, General Motors, has (with its associated firms) about a quarter of the world's automobile market. Aviation has been incompletely deregulated, and in only two markets: America and Europe. Everywhere else, governments dictate who flies under what rules. These aim to preserve state-owned national flag-carriers, run for prestige rather than profit. And numerous restrictions on foreign ownership impede cross-border airline mergers. In America, the big network carriers face barriers to exit, which have kept their route networks too large. Trade unions resisting job cuts and Congressmen opposing route closures in their territory conspire to block change. In Europe, liberalization is limited by bilateral deals that prevent, for instance, British Airways (BA) flying to America from Frankfurt or Paris, or Lufthansa offering transatlantic flights from London's Heathrow. To use the car industry analogy, it is as if only Renaults were allowed to drive on French motorways. In airlines, the optimists are those who think that things are now so had that the industry has no option but to evolve. Frederick Reid, president of Delta Air Lines, said earlier this year that events since the September 11th attacks are the equivalent of a meteor strike, changing the climate, creating a sort of nuclear winter and leading to a "compressed evolutionary cycle". So how, looking on the bright side, might the industry look after five years of accelerated development?

单选题Even today, when air and road travel has made Africa so readily accessible to Europeans and Americans, there are innumerable aspects of African life which tend to take one by surprise. The unfamiliar lies hidden every where, and the presence of Western culture seems merely to emphasize this unfamiliarity. Basically, the essence of our reaction to the strange, the unfamiliar, is a sense of fear. Every country contains landscapes that arouse unease-whether it be some remote Alpine valley, the wild lavender fields of Upper Province, or a lonely Norwegian fjord at twilight But in my own experience West Africa contains more weird and eerie regions-rain-forest, mangrove swamp, parched plains of red earth-than any other place that I have seen. It is not only in the foreigner that these landscapes evoke fear. A large part of all old African religions is devoted to soothing the unknown and the unseen-evil Spirits which live in a particular tree or a particular rock, a thousand varieties of ghosts and witches, the ever-present spirits of dead ancestors or relatives. I have myself been kept awake at night in Calabar by a friend from Lagos who was convinced that the witches of the east were out to get him, or that he was about to be kidnapped and eaten. During four and a half hours in a canoe along the creeks of the Niger delta, gliding over the still and colorless water beneath an equally still and colorless but burning sky, I, too, have experienced a sense of fear, or at least a sense of awe. Except for the ticking of the little outboard engine the silence was complete. On either hand stretched the silver-white swamps of mangrove, seeming, with their awkward exposed roots, to be standing knee-deep in the water. Where the creek narrowed you could peer deep into these thickets of mangroves-vistas secret, interminable and somehow meaningless. There was no sign of life except for the shrill screech of some unseen bird. I was on my way to the ancient slaving port of Bonny .which we reached in late afternoon. Scrambling up some derelict stone steps (slithery with slime and which had managed to detach themselves from the landing-stage so that you had to jump a two-foot gap to reach wet land), I found myself in an area of black mud and tumbled blocks of stone.

Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center.{{B}}Passage One{{/B}} Andrea had never seen an old lady hitchhiking before. However, the weather and the coming darkness made her feel sorry for the lady. The old lady had some difficulty in climbing through the car door, and pushed her big brown canvas shopping bag down onto the floor under her feet. She said to Andrea, in a voice that was almost a whisper, "Thank you dear - I'm just going to Brock Bourne" Something in the way the lady spoke, and the way she never turned her head, made Andrea uneasy about this strange hitchhiker. She didn't know why, but she felt instinctively that there was something wrong, something old, and something dangerous. But how could an old lady be dangerous? It was absurd. Careful not to turn her head, Andrea look sideways at her passenger. She studied the hat, the dirty collar of the dress, the shapeless body, and the arms with their thick black hairs. Thick black hairs? Hairy arms? Andrea's blood froze. This wasn't a woman. It was a man. At first, she didn't know what to do. Then suddenly, an idea came into her racing, terrified brain. Swinging the wheel suddenly, she threw the car into a skid, and brought it to a halt. "My god!" she shouted. "A child! Did you see the child? I think I hit her. " The "old lady" was clearly shaken by the sudden skid. "I didn't see anything dear," she said. "I don't think you hit anything. " "I am sure it was a child!" insisted Andrea. "Could you just get out and have a look? Just see if there is anything on the road?" she held her breath. Would her plan work? It did. The passenger slowly climbed out to investigate. As soon as in front of her vehicle, Andrea gunned the engine and accelerated madly away, and soon she had put a good three miles between herself and the awful hitchhiker. It was only then that she thought about the bag lying on the floor in front of her. Maybe the bag would provide some information about the real identity about the man. Pulling into the side of the road, Andrea opened the heavy bag curiously. It contained only one item — a small hand axe, with a razor-sharp blade. The axe, and the inside of the bag, were covered with the dark red stains of dried blood. Andrea began to scream.
