单选题 Passage 2 Believe it or not, optical illusion (错觉) can cut highway crashes. Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons (人字形)painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down. Now the American Association Foundation for Traffic Safety in Washington D. C. is planning to repeat Japan's success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes. Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatest-curves, exit slopes, traffic circles, and bridges. Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bar. Chevrons, scientists say, not only give drivers the impress ion that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.

单选题{{B}}Passage 1{{/B}} It was a normal day in the life of the American Red Cross in Greater New York. First, part of a building on West 140th Street, in Harlem, fell down. Beds tumbled through the air, people slid out of their apartments and onto the ground, three people died, and the Red Cross was there, helping shocked residents find temporary shelter, and food and clothing. Then it was back downtown for that evening's big fund-raiser, the Eleventh Annual Red Cross Award Dinner Dance, at the Pierre. "That's why I have bad hair tonight," Said Christopher Peake, a Red Cross spokesman who had spent much of the day at the Harlem scene, in the drizzling rain. He was now in a tuxedo, and actually his hair didn't look so bad, framed by a centerpiece of tulips and jonquils, and perhaps improved by subdued lighting from eight crystal chandeliers. Definitely not having a bad-hair night was Elizabeth Dole, the wife of Senator Robert Dole and the president of the American Red Cross. President Dole has chestnut-colored Republican hair, which was softly coifed, and she was wearing a fitted burgundy velvet evening suit ("Someone made it for me! I love velvet, she exclaimed, in her enthusiastic, Northern Carolina hostess voice) and sparkling drop earrings. Of course, she hadn't been standing in the rain in Harlem; she had just flown up on the three-o'clock shuttle from Washington. Dole is extremely pretty, with round green eyes and a full mouth and a direct personality. She tilts her head attentively when she listens. She was the recipient of the evening's award; previous award winners have included Alice Tully, Princess Yasmin Aga Khan, ...and, most recently, Brooke Astor. Not exactly a sequence at the end of which you would expect to find Elizabeth Dole, but award givers are famous for having political instincts as well as philanthropic ones. Surrounded by the deep-blue swags and golden draperies of the ballroom were more than thirty-five dinner tables set with groupings of candles and floral centerpieces and Royal Doulton china, American Express was there. So were Bristol-Myers Squibb; Coopers the New York Life; ...and Price Waterhouse. The actress Arlene Dahl, with her rather red hair and her bearded husband, presided over one table. Otherwise, it was a typical, faceless, captain-of-industry fund raiser (No models! No stars!), of which there seems to be at least one every night in New York City. It was not a society night, 'but still the evening raised four hundred and thirty thousand dollars.

单选题Here, the very important concept of the tool must enter into our consideration of purposive action. The primary form of the teleological sequence is that in which our action produces reactions in an external object, and these reactions, following a course determined by their own nature. Culminate in the desired effects. The use of tools involves interposing another factor between the subject and this object, a factor that occupies an intermediate position not only in terms of space and time but also in terms of its content. For on the one hand a tool is a mere object which is mechanically effective, but on the other hand it is also an object that we not merely operate upon, but operate with, as with our own hands. The tool is an intensified instrument, for its form and existence are predetermined by the end. Whereas in the primary teleological process natural objects are only later made to serve our purposes. The person who plants a seed in order to enjoy the fruit of the plant at a later date, instead of being satisfied with wild fruits, acts teleologically, but the purposive action is limited to his hand. If, however, he uses a spade and hoe he removes himself further from the point at which natural processes operate by themselves, and he enhances the subjective factor in relation to the objective factor. By using tools we deliberately add a new link to the chain of purposive action, thus showing that the straight road is not always the shortest. The tool is typical of what we might call our creations in the external world; on the one hand it is formed exclusively by our own powers, and on the other it is devoted entirely to our own purposes. Because the tool is not itself an end it lacks the relative independence that the end implies, either as an absolute value or as something that will produce an effect upon us; it is an absolute means. The principle of the tool is not only effective in the physical world. Where self-interest is not focused directly upon material production, but mental conditions or non-material events are involved, the tool attains a still more refined form, inasmuch as it is now really the creation of our will and does not have to compromise with the attributes of a material substance that is fundamentally alien to purpose. The most typical instances of this kind of tool are perhaps social institutions, by means of which the individual can attain ends for which his personal abilities would never suffice. Membership of a state provides the protection that is a prerequisite for most individual purposive action; but leaving aside this most general aspect, the particular institutions of civil law make possible for the individual achievements that would otherwise be denied to him. In the roundabout legal forms of contract, testament, adoption, etc, the individual possesses a collectively established tool that multiplies his own powers, extends their effectiveness and secures their ends. Fortuitous elements are eliminated and the homogeneity of interests makes possible an increase in the services rendered: from the interaction of individuals there develop objective institutions which become the junction of countless individual teleological sequences and provide an efficient tool for otherwise unattainable purposes. It is the same with religious rites, which are tools of the Church, serving to objectify the typical emotions of the religious community. They are, no doubt, a digression from the ultimate end of religious sentiment, but a digression by means of a tool which, in contrast to all material tools, serves exclusively those ends that the individual is otherwise unable to attain.

单选题{{B}}Directions:{{/B}} There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. In most sectors of the economy, it is the seller who attempts to act a potential buyer with various inducements of price, quality, and utility, and it is the buyer who makes the decision. In the health care industry, however, the doctor-patient relationship is a mirror image of the ordinary relationship between producer and consumer. Once an individual has chosen to see a physician, the physician usually makes all significant purchasing decisions: whether the patient should return "next Wednesday", whether X-rays are needed, whether drugs should be prescribed, etc. This is particularly significant in relation to hospital care. The physician must certify the need for hospitalization, determine what procedures will be performed, and announce when the patient may be discharged. The patient may be consulted about some of these decisions, but in the main it is the doctor's judgments that are final. Little wonder then that in the eyes of the hospital it is the physician who is the real "consumer". As a consequence, the medical staff represents the "power centre" in hospital policy and decision-making, not the administration. Although usually, there are in this situation four identifiable participants--the physician, the hospital, the patient and the payer (generally an insurance carrier or government) -- the physician makes the essential decision for all of them. The hospital becomes an extension of the physician, the payer generally meets most of the bona fide bills generated by the physician/ hospital, and for the most part, the patient plays a passive role. In routine or minor illensses, or just plain worries, the patient's options are, of course, much greater with respect to use and price. But in illnesses that are of some significance, such choice tends to evaporate. And it is for these illnesses that the bulk of the health care dollar is spent. We estimate that about 75 --80 percent of health care expenditures are determined by physicians. For this reason, economy measures directed at patients or the general public are relatively ineffective.

单选题Valvular heart diseases are quite common, essentially resulting in impaired blood flow and were very difficult to treat. Some 30 years ago, it became possible to replace .diseased valves with prostheses to impose a greater control over blood flow. Early devices were of the mechanical variety, in which devices like ball-in-a-cage or tilting disc would be used to allow blood to flow under near-normal conditions. Although a few mechanical problems were encountered in the early days, the major difficulty lay with the tendency for any foreign material to initiate a blood clot. So, all valve recipients have to be given anticoagulant therapy. This is not particularly desirable for the patients, who may develop bleeding problems, and in any case is not always successful. Although good results are achieved with these valves, it was considered necessary to develop alternatives and the direction was that of natural tissues. It's not possible to transplant heart valves untreated because of rejection phenomena, but it became apparent that collagenous tissue could be cross-linked by glutaraldehyde and prepared in the form of a heart valve. Two sources of tissue were considered for this purpose, bovine pericardium ( collagenous tissue derived from the wall of a cow's heart) and porcine valves (heart valves taken from pigs) and the resulting "bioprosthetic valve" appeared to be very promising. It was particularly important that these patients didn't need anticoagulation. Unfortunately, these valves have not proved very durable, the cross-linked collagen suffering from slow calcification and deterioration so most of the replacement valves themselves need to be replaced within a decade. This would tend to suggest that the mechanical valves give superior performance, notwithstanding the anticoagulation problem, and a move back towards their use might have been expected. However, most of the valves in current use incorporate an alloy'( usually Stellite) for the housing, and a carbon coated occuluder. The complex shapes of some of the housing have required combinations of casting and welding technologies to be used in their construction and serious problems have arisen with a valve design from one manufacturer, where a small number of catastrophic fractures have occurred within the housing. In patients where this valve has been used to treat aortic valve disease, this fracture is usually fatal and although the risks are small, the problem is important to the industry. Also, at a time when this dichotomy is exercising the minds of surgeons, scientists and regulatory bodies alike, the emergence of the disease BSE in cattle has placed even further restrictions on the use of animal tissue for this type of application and the whole question of prosthetic heart valves has been turned from a reasonable successful example of reconstructive implant surgery to a very confused area. This serves to highlight some of the very varied problems of facing the use of biomaterials.
