单选题Once upon a time, innovation at Procter ＆ Gamble flowed one way: from the United States outward. While the large Cincinnati-based corporation was no stranger to foreign markets, it usually Sold them products that were already familiar to most Americans. Many Japanese families, for instance, swaddle their babies in Pampers diapers, and lots of Venezuelans brush their teeth with Crest. And of course (company executives assumed) Americans at home wanted these same familiar, red-white and blue brands. We might buy foreign-made cars, or chocolates, or cameras but household cleaners and detergents? Recently, however, P＆G broke with this long-standing tradition. Ariel, a P＆G laundry detergent, was born overseas, and is a familiar sight on store shelves in Europe and Latin America. Now bilingual packages of Ariel Ultra. a super-concentrated cleaner. are appearing on supermarket shelves in Los Angeles. Ariel's appearance in the United States reflects demographic changes making Hispanics the nation's fastest-growing ethnic group. Ariel is a hit with this population. In fact, many Mexican immigrants living in Southern California have been "importing" Ariel from Tijuana, Mexico. "Hispanics knew this product and wanted it," says P＆G spokeswoman Marie Salvado. "We realized that we couldn't convince them to buy (our) other laundry detergents." P＆G hopes that non-Hispanic consumers will give Ariel a try too. Ariel's already strong presence in Europe may provide a springboard for the company to expand into other markets as well. Recently P＆G bought Rakona. Czechoslovakia's top detergent maker. Ariel, currently a top seller in Germany, is likely to be one of the first new brands to appear in Czech supermarkets. And Ariel is not the only foreign idea that the company hopes to transplant back to its home territory. Cinch, an all-purpose spray cleaner similar to popular European products, is currently being test-marketed in California and Arizona. Traditionally Americans have used separate cleaners for different types of surfaces, but market research shows that American preferences are becoming more like those in other countries. Insiders note that this new reverse flow of innovation reflects more sweeping changes at Procter ＆ Gamble. The firm has hired many new Japanese, German. and Mexican managers who view P＆G's business not as a one-way flow of American ideas, but a two-way exchange with other markets. Says Bonita Austin of the investment firm Wertheim-Schroeder, "When you met with P＆G's top managers years ago, you wouldn't have seen a single foreign face." Today, "they could even be in the majority." As Procter ＆ Gamble has found, the United States is no longer an isolated market. Americans are more open than ever before to buying foreign-made products and to selling U. S. -made products overseas.

单选题Our next task is to consider the policies and principles a ruler ought to follow in dealing with his subjects or with his friends. Since I know many people have written on this subject, I am concerned it may be thought presumptuous for me to write on I as well, especially since what I have to say, as regards this question in particular, will differ greatly from the recommendations of others. But my hope is to write a book that will be useful, at least to those who read it intelligently, and so I thought it sensible to go straight to a discussion of how things are in real life and not waste time with discussion of an imaginary world. For many authors have constructed imaginary republics and principalities that have never existed in practice and never could; for the gap between how people actually behave and how they ought to behave is so great that anyone who ignores everyday reality in order to live up to an ideal will soon discover he has been taught how to destroy himself, not how to preserve himself. For anyone who wants to act the part of a good man in all circumstances will bring about his own ruin, for those he has to deal with will not all be good. So it is necessary for a ruler, if he wants to hold on to power, to learn how not to be good, and to know when it is and when it is not necessary to use this knowledge. Let us leave to one side, then, all discussion of imaginary rulers and talk about practical realities. I maintain that all men, when people talk about them, and especially rulers, because they hold positions of authority, are described in terms of qualities that are inextricably linked to censure or to praise. So one man is described as generous, another as a miser; one is called open-handed, another tight-fisted; one man is cruel, another gentle; one untrustworthy, another self-important; one promiscuous, another monogamous; one straightforward, another duplicitous; one tough, another easy-going; one serious, another cheerful; one religious, another atheistical; and so on. Now I know everyone will agree that if a ruler could have all the good qualities I have listed and none of the bad ones, then this would be an excellent state of affairs. But one cannot have all the good qualities, nor always act in a praiseworthy fashion, for we do not live in an ideal world. You have to be canny enough to avoid being thought to have those evil qualities that would make it impossible for you to retain power; as for those that are compatible with holding on to power, you should avoid them if you can; but if you cannot, then you should not worry too much if people say you have them. Above all, do not be upset if you are supposed to have those vices a ruler needs if he is going to stay securely in power, for, if you think about it, you will realize there are some ways of behaving that are supposed to be virtuous, but would lead to your downfall, and others that are supposed to be wicked, but will lead to your welfare and peace of mind.

单选题Can animals have a sense of humor? Sally Blanchard, publisher of a newsletter called the Pet Bird Report, thinks a pet parrot may have pulled her leg. That's one explanation for the time her African gray parrot, named Bongo Marie, seemed to feign distress at the possible death of an Amazon parrot named Paco. It happened one day when Blanchard was making Cornish game hen for dinner. As Blanchard lifted her knife, the African gray threw back its head and said, "Oh, no! Paco!" Trying not to laugh, Blanchard said, "That's not Paco," and showed Bongo Marie that the Amazon was alive and well. Mimicking a disappointed tone, Bongo Marie said, "Oh, no," and launched into a hoarse laugh. Was the parrot joking when it seemed to believe the other bird was a goner? Did Bongo Marie comprehend Blanchard's response? Studies of African grays have shown that they can understand the meaning of words—for example, that red refers to a color, not just a particular red object. Parrots also enjoy getting a reaction out of humans, and so, whether or not Bongo Marie's crocodile tears were intentional, the episode was thoroughly satisfying from the parrot's point of view.

单选题Writers learn as apprentices do except that they have no master to work for except themselves and the market. The fact is that writing is an empirical art, which can only be learned by doing it. This fact is no reflection on the art of writing. Because skill is acquired in a seemingly haphazard way it is none the worse, indeed sometimes the better, for it. As in every art you must have at least the foundation of a gift, without which it is useless to proceed; but if the foundation exists, then success—not merely economic— is largely a matter of persistence and of making the most of opportunities. Experience is a hard school. Wastage among aspiring writers is high and most survivors have to rely on another job. The pros and cons of that situation are debatable. Working out in the world is not solely a form of insurance; it can also be a vital source of material and incentive, particularly for the fiction writer. Many well-known authors labored away at other jobs for part or all of their lives, and either profited there from or made their names notwithstanding. Economic security frees the mind from worry, but a routine job also consumes mental energy which might otherwise be harnessed to creative output. This applies as much to freelance journalism and other ancillary activities of authorship as to nonliterary employment. A regular stint of reviewing, reading manuscripts for publishers, broadcasting, lecturing, and the like, may oil the machinery of the mind, but it may also use up horsepower to the point of exhaustion. Moreover, continuity of creation is often vital—whether for the construction of a work of fiction or for historical research or, indeed, for any idea that has to be digested into literary form. Interruptions nowadays, however, are a professional hazard that all authors have to contend with, but they are not insuperable and not the worst threat to a living literature.

单选题1 Gene therapy and gene-based drugs are two ways we could benefit from our growing mastery of genetic science. But there will be others as well. Here is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the coming years. While it's true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells haven't begun to specialize. Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells—brain cells in Alzheimer's, cardiac cells in heart disease, pan creatic cells in diabetes, to name a few. If doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue. It was incredibly difficult, but last fall scientists at the University of Wisconsin man aged to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations; but if ef forts to understand and master stem-cell development prove successful, doctors will have a therapeutic tool of incredible power. The same applies to cloning, which is really just the other side of the coin; true clo ning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, ge netically identical to its parent. For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year. Human cloning, on the other hand, may be technically feasible but legally and emo tionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells, the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true "miracle cure. /
