单选题{{B}}Directions:{{/B}} Read the following passage, decide on the best one of the choices marked A, B, C, and D for each question or unfinished statement and then mark the corresponding letter with a single bar across the square bracket on ANSWER SHEET. Passage One The Commercial Revolution was not confined, of course, to the growth of trade and banking. Included in it also were fundamental changes in methods of production. The system of manufacture developed by the craft guilds in the later Middle Ages was rapidly becoming defunct. The guilds themselves, dominated by the master craftsmen, had grown selfish and exclusive. Membership in them was commonly restricted to a few privileged families. Besides, they were so completely choked by tradition that they were unable to make adjustments to changing conditions. Moreover, new industries had sprung up entirely outside the guild system. Characteristic examples were mining and smelting and the woolen industry. The rapid development of these enterprises was stimulated by technical advances, such as the invention of the spinning wheel and the discovery of a new method of making brass, which saved about half of the fuel previously used. In the mining and smelting industries a form of organization was adopted similar to that which has prevailed ever since. But the most typical form of industrial production in the Commercial Revolution was the domestic system, developed first of all in the woolen industry. The domestic system derives its name from the fact that the work was done in the homes of industrial artisans instead of in the shop of a master craftsman. Since the various jobs in the manufacture of a product were given out on contract, the system is also known as the putting out system. Notwithstanding the petty scale of production, the organization was basically capitalistic. The raw material was purchased by an entrepreneur and assigned to individual worker, each of whom would complete his allotted task for a stipulated payment. In the case of the woolen industry the yam would be given out first of all to the spinners, then to the weavers, fullers, and dyer in succession. When the cloth was finally finished, it would be taken by the clothier and sold in the open market for the highest price it would bring.

单选题Forty years ago no one was concerned about the health of the ocean, in spite of the fact that many fisheries were being over-harvested, toxic wastes were being dumped in the sea, and developers were beginning to seriously disrupt coastlines. In those days, the magnitude of the problems was small, even though it was obvious that if the trends continued people would face severe economic and personal hardship in the future. People just didn't understand, nor did they care. Unfortunately many of our concerns were realized, but the situation could have been much worse, had we, and others, not taken action to inform people about the ocean and the need to protect it. During our campaign to share the wonders of the sea and alert the public about the need to protect it, we have used every medium available—personal appearances, the printed word, and television. Now there is a new medium that is even more effective than its predecessors. Thanks to the Internet and computers, people can not only receive linear stories, but they can actually participate in them, exploring and learning at their own pace and as their curiosity dictates. I am tremendously impressed with the personalization of what had been labeled by skeptics as the most impersonal medium yet developed. For these reasons I have made a major commitment of time and resources to dive into this sea of electronic marvels. I'm swimming hard to keep up, but when I look around I find I'm not alone. We are all learning together and it is an adventure I am finding immensely rewarding. I have been encouraged by our first modest dunking in this new world. We recently completed a CD-ROM, Jean-Michel Cousteau's World. Cities Under the Sea-Coral Reefs. A couple of months ago I was in Fiji to celebrate the 1997 International Year of the Reef and presented our Cities under the Sea CD-ROM to a group of children. I was impressed to see how quickly they grasped our concepts and how they directed their own learning process, thanks to the flexibility of the medium. It was particularly exciting to see kids squeal with delight as they responded to questions and the computer rewarded them when they got the correct answers. I want young people to experience the mystery and wonder of our oceans. I want them to understand how precious and vulnerable our environment is. Young people need to be taught to take responsibility for ensuring that their heritage will be protected and used wisely. Hopefully the next generation will do a better job than mine has. I believe individuals must be personally involved and I am counting on the Internet to be the medium through which people can experience, learn, and take action I am counting on young people with their idealism and energy to create a better future—it is too important to be left to bureaucrats and politicians.

单选题Technically, any substance other than food that alters our bodily or mental functioning is a drug. Many people mistakenly believe the term drug refers only to some sort of medicine or an illegal chemical taken by drug addicts. They don"t realize that familiar substances such as alcohol and tobacco are also drugs. This is why the more neutral term substance is now used by many physicians and psychologists. The phrase substance abuse is often used instead of drug abuse to make clear that substances such as alcohol and tobacco can be just as harmfully misused as heroin and cocaine. We live in a society in which the medicinal and social use of substances (drugs) is pervasive: an aspirin to quiet a headache, some wine to be sociable, coffee to get going in the morning, a cigarette for the nerves. When do these socially acceptable and apparently constructive uses of a substance become misuses? First of all, most substances taken in excess will produce negative effects such as poisoning or intense perceptual distortions. Repeated use of a substance can also lead to physical addiction or substance dependence. Dependence is marked first by an increased tolerance, with more and more of the substance required to produce the desired effect, and then by the appearance of unpleasant withdrawal symptoms when the substance is discontinued. Drugs (substances) that affect the central nervous system and alter perception, mood, and behavior are known as psychoactive substances. Psychoactive substances are commonly grouped according to whether they are stimulants, depressants, or hallucinogens. Stimulants initially speed up or activate the central nervous system, whereas depressants slow it down. Hallucinogens have their primary effect on perception, distorting and altering it in a variety of ways including producing hallucinations. These are the substances often called psychedelic (from the Greek word meaning mind-manifestation) because they seemed to radically alter one"s state of consciousness.

单选题At some time around 2300BC, give or take a century or two, a large number of the major civilizations of the world collapsed, in Mesopotamia, Egypt, Israel, Anatolia, and Greece, as well as in Afghanistan and China. All of them the first urban civilizations fell into rain at more or less the same time. A thousand years later, around 1200BC, many of the civilizations of the same regions again collapsed at about the same time. The reasons for these widespread and apparently simultaneous disasters which coincided with changes to cultures and societies elsewhere, such as in Britain, have long been a fascinating mystery. Traditional explanations included warfare, famine, and more recently systems collapse, but the apparent absence of direct archaeological or written evidence for causes, as opposed to effects, has led many archaeologists and historians into a resigned assumption that no definite explanation can be found. Over the past 15 years, however, a new type of 'natural disaster' has been proffered which is beginning to be regarded by many scholars as the most probable single explanation for widespread and simultaneous cultural collapse. The new theory has been advanced largely by astronomers and remains largely unknown by archaeologists (notable exceptions include Professor Baillie of Belfast and Dr. Euan Mackie in Glasgow). The theory postulates that the disasters were caused by the impact of comets or other types of cosmic debris on the Earth. French archaeologist Chude Schaeffer, in 1948, published his analysis and compared the destruction layers of more than 40 archaeological sites. He was the first scholar to detect that all of the sites had been totally destroyed several times in the Early, Middle and Late Bronze Age, apparently simultaneously. Since the damage did not show signs of military or other human involvement, and, in any case, was too excessive, he argued that repeated seismic activity might have been responsible. Schaeffer was not taken seriously in 1948, but since then natural scientists have found widespread and unambiguous evidence for abrupt climate change, sudden sea level changes, catastrophic inundations, and seismic activity at several periods since the last Ice Age, particularly around 2300BC. Areas such as the Sahara, which were once farmed, became deserts. Tree rings show disastrous conditions at 2350BC. In Mesopotamia the land appears to have been inundated, devastated, or totally burned. Scholars who, following Schaeffer, favor earthquakes as the principal cause of civilization collapse, argue that the world can expect earthquakes every 1000 ~2000 years, leading to abandonment of sites; while scholars who prefer climate change as the principal cause argue that severe droughts caused agriculture to fail and that .societies inexorably fell apart as a result. The question remained what caused the climate change or the earthquakes. By the late 1970's British astronomers Clube and Napier of Oxford University had begun to investigate cometary impact as the ultimate cause. In 1980, the Nobel prize-winning chemist Luis Alvarez and his colleagues published their paper arguing that a cosmic impact had caused the extinction of the dinosaurs. He showed that large amounts of iridium found in geological layers from the time of the dinosaurs had a cosmic origin. Alvarez's paper stimulated further research by Clube and Napier, Professor Mark Bailey, Duncan Steel and Sir Fred Hoyle. All now support the theory of cometary impact and what is now known as the British School of Coherent Catastrophism.
