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.

单选题{{B}}Passage Three{{/B}} The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance or the ecological(生态的)balance as it is known. Many of these waste products can be prevented or disposed(处理) of sensibly, but clearly while more and more new goods are produced and made complex, there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people therefore see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing population. However, the land itself is gradually becoming worn out as it is being used, in some cases, too heavily, and artificial fertilizers(人造肥料) cannot bring back the balance. Whatever is underlying(潜在的)reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter(杂乱的废物)and waste. Food is wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by persuading many of us to buy things we don't want to buy. Pollution and waste continue to be a problem everyone can help to solve by cutting out unnecessary buying, excess consumption and careless disposal of the products we use in our daily lives.

单选题{{B}}Passage Five{{/B}} Nanotechnology, according to its fans, will jump-start a new industrial revolution with molecular-sized structures as complex as the human cell and 100 times stronger than steel. The new technology transforms everyday products and the way they are made by manipulating atoms so that materials can be shrunk, strengthened and lightened all at once. To date only modest nanotech-based products—such as stain-resistant fabrics and fresh food packaging—have entered the market, but some scientists predict nanotechnology will eventually be the only game in town. "It will be a ubiquitous technology," said George Stephanopoulos, professor of chemical engineering at the Massachusetts Institute of Technology. He echoes other nanotech supporters who say industrial countries are already sliding toward its use in every aspect of manufacturing. Aided by recent advances in microscopes, scientists can now place single atoms where they want for the first time. The potential applications are numerous, with microscopic computers, cancer-killing antennae and nonpolluting car engines on the distant horizon. When it's all going to happen, though, is another matter. According to most scientific accounts, the nanotech future may be 10 to 20 years off. Major hurdles need to be jumped. First, there is a lack of economic mass production. Some of the more complicated devices would require exact placement of billions of atoms. "It may take the lifetime of the universe to complete the construction of (such a) device," said George Barbastathis, assistant professor at MIT. Another challenge is bridging the nanoscale and macroscopic, he said. In other words, the smallness of a nano device is useless when it must be attached to large wires. It's unclear how scientists will overcome these problems. And fears derived from science fiction threaten to derail nanotechnology even as it emerges, in much the same way popular anxiety over "super-weeds" and "frankenfoods" have hobbled biotechnology in agriculture and fear of "designer babies" has set back stem-cell research. Lured by a market with billions of dollars in potential profits, giants like GE, Intel, Motorola and IBM are already heavily involved in research. Worldwide, the two industries with the potential to win big with nanotechnology are electronics and biotechnology, according to MIT researchers. On the biotech front, scientists are promoting the notion of nanoparticles made from gold that could be triggered remotely to heat and kill individual cancer cells. Nanotechnology holds equal promise for wealth creation, hut there isn't a consensus among venture capitalists on how to realize it. "Which direction is it going to work out in? That's the question on everyone's mind," Gang Chen, an associate professor at the MIT, told scientists at a Boston nano gathering.
