单选题Sex prejudices are based on and justified by the ideology that biology is destiny. According to this ideology, basic biological and psychological differences exist between the sexes. These differences require each sex to play a separate role in social life. Women are the weaker sex both physically and emotionally. Thus, they are naturally suited, much more so than men, to the performance of domestic duties. A woman's place, under normal circumstances, is within the protective environment of the home. Nature has determined that women play caretaker roles, such as wife and mother and homemaker. On the other hand, men are best suited to go out into the competitive world of work and politics, where serious responsibilities must be taken on. Men are to be the providers; women and children are "dependents". The ideology also holds that women who wish to work outside the household should naturally fill these jobs that are in line with the special capabilities of their sex. It is thus appropriate for women, not men, to be employed as nurses, social workers, elementary school teachers, household helpers, and clerks and secretaries. These positions are simply an extension of women's domestic role. Informal distinctions between "women's work" and "men's work" in the labor force, according to the ideology, are simply a functional reflection of the basic differences between the sexes. Finally, the ideology suggests that nature has worked her will in another significant way. For the human species to survive over time, its members must regularly reproduce. Thus, women must, whether at home or in the labor force, make the most of their physical appearance. So goes the ideology. It is, of course, not true that basic biological and psychological differences between the sexes require each to play sex-defined roles in social life. There is ample evidence that sex roles vary from society to society, and those role differences that to exist are largely learned. But to the degree people actually believe that biology is destiny and that nature intended for men and women to make different contributions to society, sex-defined roles will be seen as totally acceptable.

单选题In patients with Huntington"s disease, it"s the part of the brain called the basal ganglia that"s destroyed. While these victims have perfectly intact explicit memory systems, they can"t learn new motor skills. An Alzheimer"s patient can learn to draw in a mirror but can"t remember doing it; a Huntington"s patient can"t do it but can remember trying to learn. Yet another region of the brain, an almond-size knot of neural tissue seems to be crucial in forming and triggering the recall of a special subclass of memories that is tied to strong emotion, especially fear. These are just some of the major divisions. Within the category of implicit memory, for example, lie the subcategories of associative memory—the phenomenon that famously led Parlor"s dogs to salivate at the sound of a bell which they had learned to associate with food and of habituation, in which we unconsciously file away unchanging features of the environment so we can pay closer attention to what"s new and different upon encountering a new experience. Within explicit, or declarative memory, on the other hand, there are specific subsystems that handle shapes, textures such as faces, names—even distinct systems to remember nouns vs. verbs. All of these different types of memory are ultimately stored in the brain"s cortex, within its deeply furrowed outer layer—a component of the brain dauntingly more complex than comparable parts in other species. Experts in brain imaging are only beginning to understand what goes where, and how the parts are reassembled into a coherent whole that seems to be a single memory is actually a complex construction. Think of a hammer, and your brain hurriedly retrieves the tool"s name, its appearance, its function, its heft and the sound of its clang, each extracted from a different region of the brain. Fail to connect person"s name with his or her face, and you experience the breakdown of that assembly process that many of us begin to experience in our 20s and that becomes downright worrisome when we reach our 50s. It was this weakening of memory and the parallel loss of ability to learn new things easily that led biologist Joe Tsien to the experiments reported last week. "This age-dependent loss of function," he says, "appears in many animals, and it begins with the onset of sexual maturity." What"s happening when the brain forms memories—and what fails with aging, injury and disease—involves a phenomenon known as "plasticity". It"s obvious that something in the brain changes as we learn and remember new things, but it"s equally obvious that the organ doesn"t change its overall structure or grow new nerve cells wholesale. Instead, it"s the connections between new cells—and particularly the strength of these connections that are altered by experience. Hear a word over and over, and the repeated firing of certain cells in a certain order makes it easier to repeat the firing pattern later on. It is the pattern that represents each specific memory.

单选题Men have often been praised by being told that they were as smart as a Philadelphia lawyer. No one knows why there is something special about Philadelphia lawyers, but the expression "smart as a Philadelphia lawyer" seems to have come from a famous trial early in the 18th century. An Englishman, William S. Cosby arrived in New York as the royal governor of the province. He was a tyrant. He wanted to make money quickly and he ruled the province with no thought for the law or the rights of the people. Among those who opposed his rule was John Peter Zinger who came to America from Germany. Mr. Zinger started a newspaper which praised liberty and sharply criticized the governor. Governor Cosby arrested Mr. Zinger, charged him with slander and kept him in prison for 9 months. Mr. Zinger could not find a New York lawyer to defend him because of the governor's power. But a leading lawyer from Philadelphia agreed to defend Mr. Zinger. He was Andrew Hamilton, white-haired and almost 80 years old. The trial opened, the jury chosen and charges read. At that time, the law on slander said that jury could decide only if the person accused published in the newspaper named in the charges. The question of whether words published were true or not was to be decided by the judge. Mr. Zinger told the court he was innocent. Then the lawyer from Philadelphia rose, admitted that Mr. Zinger did publish the newspaper as charged. But Mr. Hamilton continued. The publishing of a newspaper does not make a person guilty of slander. He said that words themselves must be proved false or slanderous; Otherwise Mr. Zinger is innocent. The judge warned Mr. Hamilton that he, the judge, would decide if the words were slanderous or not. Mr. Hamilton quickly turned to the jury and asked them to decide. He said that it was their right to decide whether the alleged slander was in fact the truth. In his final statement to the jury, Mr. Hamilton said the question was much bigger than the charges against Mr. Zinger. He said the question was liberty and right of people to oppose dishonesty and tyranny by speaking and writing the truth. After a brief discussion the jury declared that Mr. Zinger was not guilty and cheers broke out in the courtroom. The decision established the principle of freedom of the press in the American Colonies. Mr. Hamilton was praised as a hero. Through the years the fame of Mr; Zinger trial and praise for Mr. Hamilton has spread throughout the country. Anti so it is believed that the expression "as smart as a Philadelphia lawyer" honors the man from Philadelphia who successfully de- fended the freedom of the press to print the truth.

单选题There is a popular English belief that if you can't get in the water, you might as well get on it. It may be that the seas around our coasts are too chill and uninviting for round-the-year bathing, or that in many eases treacherous currents and sharp incisor-like rocks beneath the water discourage all but the most venturesome. Perhaps the real answer is that we are islanders and islands, on the whole, tend to produce sea-faring people. Our early history of exploration and discovery, to say nothing of downright piracy, goes some way to support this. However that may be, the Englishman is not just content to get on the sea, he is also irresistibly compelled to get on his inland waterways. Our rivers, canals and lakes, besides proving a cheap, if relatively slow form of transport, attract a regular army of enthusiastic amateurs who spend their winters scraping and painting their boats in readiness for the warmer weather, some even going so far as to build their own craft. When spring comes, the proud owners take to the water in their little boats, white sails flapping, like so many ducks. There are of course innumerable rowing boats, punts, skiffs and dinghies, and superior, motor-powered cabin cruisers whose owners wear yachting caps and nautical-looking sweaters. These last, usually flying a club pennant and with a girl or two stretched out on the cabin roof, proceed at speed down the river creating a wash that sets the smaller boats bobbing and bouncing and even on occasion capsizing. Even their magnificence, however, is eclipsed by the rowing eights who streak up and down in their elegant long boats, dipping their oars to the merciless cries of the coach: "In-Out-In-Out". These are the giants of the river, bronzed and muscular, oblivious of everything but the precision of their timing and the need for speed. Any description of our inland waterways would be incomplete without reference to those who have made the water their way of life. Disregarding damp, inconvenience, gales, storms and the danger of floods, they make their homes on the water, in houseboats or converted barges, becoming, as it were, a species of human water-rat. Their original intention may have been to get away from the tension and frustration of city or suburban life, but it is soon apparent that theirs is no gipsy existence. Their homes, moored or floating, are painted in gay colours, electric light and bathrooms are installed, curtains appear at the windows and neighbours vie with one another in the cultivation of trailing pot plants and hanging baskets of flowers. The result is comfortably suburban—a dog or a eat is frequently introduced into the domestic scene—and the whole is an excellent example of the art of compromise. The owners have lost none of their creature comforts, but they have satisfied their urge to live on the water.
