单选题How does water scarcity affect people? First of all, it (31) their health. It is not that they will die of thirst; rather, the poor quality of the water (32) for cooking and drinking may make them ill. (33) our bodies require water to treat waste products, plentiful water is required for proper sanitation (卫生)—water that for much of mankind is simply not available. (34) people without adequate sanitation rose from 2.6 billion in 1990 to 2.9 billion in 1999. And sanitation is literally a matter of life and death. In a (35) statement, United Nations officials warned: "When children lack water that is fit for drinking and sanitation, virtually every aspect of their health and development is (36) ." Food production is dependent on water. Many crops, of course, are watered by rain, but in recent times irrigation has become the key (37) the world% booming population. Today percent of the world's harvest depends on irrigation. If plentiful water flows out of every tap in our home and if we have a clean toilet (抽水马桶) that conveniently washes out waste, it may be (38) to believe that the world is running out of an adequate supply of water. We should remember, however, that only 20 percent of mankind enioy such (39) .In Africa many women spend as much as six hours a day (40) water.

单选题Extraordinary creative activity has been characterized as revolutionary, flying in the face of what is established and producing not what is acceptable but what will become accepted. According to this formulation, highly creative activity transcends the limits of an existing form and establishes a new principle of organization. However, the idea that extraordinary creativity transcends established limits is misleading when it is applied to the arts, even though it may be valid for the science; Differences between highly creative art and highly creative science arise in part from a difference in their goal. For the sciences, a new theory is the goal and end result of the creative act. Innovative science produces new propositions in terms of which diverse phenomena can be related to one another in more coherent ways. Such phenomena as a brilliant diamond or a nesting bird are relegated to the role of date, serving as the means for formulating or testing a new theory. The goal of highly creative art is different: the phenomenon itself becomes the direct product of the creative act. Shakespeare's Hamlet is not a tract about the behavior of indecisive princes or the uses of political power, nor is Picasso's painting Guernica primarily a prepositional statement about the Spanish Civil War or the evils of fascism. What 'highly creative activity produces is not a new generalization that 'transcends established limits, but rather an aesthetic particular. Aesthetic particulars produced by the highly creative artist extend or exploit, rather than transcend that form. This is not to deny that a highly creative artist sometimes establishes a new principle of organization in the history of an artistic field; the composer Monteverdi, who created music of the highest aesthetic value, comes to mind. More generally, however, whether or not a composition establishes a new principle in the history of music has no bearing on its aesthetic worth. Because they embody a new principle of organization, some musical works, such as the operas of the Florentine Camerata, are of signal historical importance, but few listeners or musicologists would include these among the great works of music. On the other hand, Mozart's The Marriage of Figaro(费加罗的婚礼) is surely among the masterpiece of music even though its modest innovations are confined to extending existing means. It has been said of Beethoven that he toppled the rules and freed music from the stifling confines of convention. But a close study of his composition reveals that Beethoven overturned no fundamental rules. Rather, he was an incomparable strategist who exploited limits of the rules, forms, and conventions that he inherited from predecessors such as Haydn and Mozart, Handel and Bach—in strikingly original ways.

单选题In November of 1902, President Theodore Roosevelt was on a hunting trip in Mississippi. His hunt was going (31) that day, and he couldn't seem to find anything worth of (32) his rifle. Then, his staff captured a black baby bear for the President to shoot, but he could not. The thought of shooting a bear that was tied to a tree did not seem sporting, so he (33) the life of the baby bear and set it free Based on this story, a famous political cartoonist for the Washington Star drew a cartoon, which showed Teddy Roosevelt, rifle (34) , with his back turned on a cute(可爱的) baby bear. Morris Michtom, owner of a Brooklyn toy store, was (35) by the cartoon to make a stuffed baby bear. Intending it only as a display, he placed the stuffed bear in his toy store (36) ,and next to it placed a copy of the cartoon from the newspaper. To Miehtom's surprise, his store was flooded by customers (37) to buy. He asked for and received President Roosevelt's 38 to use his name for the hand-sewn bears that he and his wife made, and the "Teddy Bear" was born! Michtom was soon manufacturing Teddy bear (39) the thousands. The money from the sale enabled him, in 1903, to (40) the Ideal Toy Company.

单选题When an art museum wants a new exhibit, it buys things in finished form and hangs them on its walls. When a natural history museum wants an exhibit, it often must build it realistically— from a mass of material and evidence brought together by careful research. An animal, for example, must first be skinned. Photographs and measurements are used to determine the animal"s structure in a natural position fighting, resting, or feeding. Then muscle forms are built and a plaster shell is made. Finally the skin is pulled over the shell like a wet glove. This completes the animal subject. Displaying such things as stone heads, giant trees, and meteorites (陨石，陨星) is basically mechanical. Most other natural history exhibits present more difficult problems. For instance how can a creature be exhibited when it is too small to be seen clearly? In these cases larger-than-life models are built. The American Museum of Natural History has models of fleas (跳蚤), houseflies and a myriad (无数的) of other insects enlarged up to seventy-four times. The models show the stages of the insects" development and the workings of their bodies.

单选题 The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban (禁止) such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights. The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be vulnerable (易受损的) to interference raises the risk that terrorists may use radio system in order to damage navigation equipment. As worrying, though, is the passenger who can't hear the instructions to mm off his radio because the music's too loud.

单选题 Not so long ago almost any student who successfully completed a university degree could, find a good career quite easily. Companies toured the academic institutions, competing with each other to select graduates. However, those days are gone, even in Hong Kong, and nowadays graduates often face strong competition in the search for jobs. Most careers organizations highlight three stages for graduates to follow in the process of securing a suitable career: recognizing abilities, matching these to available jobs and presenting them well to possible employers. Job seekers have to make a careful assessment of their own abilities. One area of assessment should be of their academic qualifications, which would include special skills within their subject area. Graduates should also consider their own personal values and attitudes. An honest assessment of personal interests and abilities such as creative skills, or skills acquired from work experience, should also be given careful thought. The second stage is to study the opportunities available for employment and to think about how the general employment situation is likely to develop in the future. To do this, graduates can study job and position information in newspapers, or they can visit a careers office, write to possible employers for information or contact friends or relatives who may already be involved in a particular profession. After studying all the various options, they should be in a position to make informed comparisons between various careers. Good personal presentation is essential in the search for a good career, job application forms and letters should, of course, be filled in carefully and correctly, without grammar or spelling errors. Where additional information is asked for, job seekers should describe their abilities and work experience in more depth, with examples if possible. They should try to balance their own abilities with the employer's needs, explain why they are interested in a career with the particular company and try to show that they already know something about the company and its activities. When graduates go to an interview, they should prepare properly by finding out all they can about the possible employer. Dressing suitably and arriving for the interview on time are also important. Interviewees should try to give positive and helpful answers and should not be afraid to ask questions about anything they are unsure about. This is much better than pretending to understand a question and giving an unsuitable answer.
