单选题When most people think about changing their body shape, they usually focus on just losing weight. Books and magazines about dieting are among the most popular in the world. Dieting is an important part of staying fit and healthy, but losing weight by means of dieting takes time; losing weight too fast can cause great health problems. Dieting means change one"s eating habits to a healthier pattern, but many women mistake the concept of dieting and thinking that the less one eats, the better. As a result, they lose health as well as weight.
Aerobic exercise is a moderate intensity workout that, over a certain period of time, will provide the body"s use of oxygen. Nowadays, aerobic exercise has become a very trendy workout among youths. Not only is performing aerobic exercise interesting, but it is also very beneficial for health. There are different types of aerobics like jogging, swimming, kickboxing, fitness walking, inline skating, bicycling, etc. Aerobics strengthens the heart and lungs. It is also especially popular with women.
But neither of these two methods, dieting and aerobics, can help shape the body. To do this, you need to build muscle. So, if a firmer and shapelier body is your goal, 60 percent of your exercise routine should involve strengthening moves, and only 30 percent should be aerobic exercises.
For a proper body-shaping routine, you should plan three strength-training sessions a week with weights. Use weights which are as heavy as possible while still allowing you to do 8 to 12 reps of each exercise. Do one to three exercises for each muscle groups—for example, chest and biceps, or back, shoulders and triceps.
You should combine this with fast-paced aerobics activities, like swimming, cycling, walking, running, or in-line skating. Plan three to four workouts a week, 15 to 20 minutes each, increasing the pace each week.
As you build muscle, you may find that you gain weight in spite of all of your calorie-burning exercise. Don"t worry. It"s probably muscle, which is denser that fat. And muscle is also a calorie-burning tissue. With more muscle, you can bum more calories, even when you are not exercising.
When you are trying to build muscle, you need two to three servings of protein a day, but the main part of your diet should be carbohydrates. And in order to get the energy you need for a high-intensity workout, you should eat something, especially carbohydrates, an hour or so before your workout.
While weight training will firm and shape your body, it has other benefits too. It improves bone and muscle strength and bums calories, leading to improved health and a higher quality of life.

单选题Coincident with concerns about the accelerating loss of species and habitats has been a growing appreciation of the importance of biological diversity, the number of species in a particular ecosystem, to the health of the Earth and human beings. Much has been written about the diversity of terrestrial organisms, particularly the exceptionally rich life associated with tropical rain-forest habitats. Relatively little has been said, however, about diversity of life in the sea even though coral reef systems are comparable to rain forests in terms of richness of life. An alien exploring the Earth would probably give priority to the planet's dominant, most distinctive feature—the ocean. Humans have a bias toward land that sometimes gets in the way of truly examining global issues. Seen from far away, it is easy to realize that landmasses occupy one-third of the Earth's surface. Given that two-thirds of the Earth's surface is water and that marine life lives at all levels of the ocean, the total three- dimensional living space of the ocean is perhaps 100 times greater than that of land and contains more than 90 percent of all life on Earth even though the ocean has fewer distinct species. The fact that half of the known species are thought to inhabit the world's rain forests does not seem surprising, considering the huge numbers of insects that comprise the bulk of species. One scientist found many different species of ants in just one tree from a rain forest. While every species is different from every other species, their genetic makeup constrains them to be insects and to share similar characteristics with 750 000 species of insects. If basic, broad categories such as phyla and classes are given more emphasis than differentiating between species, then the greatest diversity of life is unquestionably the sea. Nearly every major type of plant and animal has some representation there. To appreciate fully the diversity of abundance of life in the sea, it helps to think small. Every spoonful of ocean water contains life on the order of 100 to 100 000 bacterial cells plus assorted microscopic plants and animals, including larva's or organisms ranging from sponges and corals to starfish and clams and much more.

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.
