单选题Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change (1) the years within the same society, how certain behavior and attitudes (2) considered taboo can become perfectly (3) and natural (4) another point in time. Topics such as death, fro example, were once considered so (5) and unpleasant that it was a taboo to even talk about them. Now with the (6) of important books such as On Death and Dying and Learning to Say Goodbye, people have become more (7) of the importance of expressing feelings about death and, (8) a result, are more willing to talk about this taboo subject. One of the newest taboos in American society is the topic of fat. (9) many other taboos, fat is a topic that Americans talk about constantly. It's not taboo to talk about fat; it's taboo to fat. The " (10) " look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their (11) as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought (12) as lazy and (13) in energy, self-discipline and self-respect. After all, people think, how can people who care about themselves, and therefore the way. they look, permit themselves to become fat? In an image-conscious society like the U. S. , thin is "in", fat is "out". It's not surprising, then, that millions of Americans have become (14) with staying slim and "in shape". The (15) of a youthful physical appearance is not, however, their sole reason for America's obsession with diet and exercise. Recent research has shown the (16) importance of diet and exercise for personal health. As in most technologically developed nations, the life-style Of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do (17) hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people's bodies can easily become weak and (18) to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising. The effect of this new appreciation of the importance of exercise is evident: parks are filled with runners and bicyclists, physical education programs are enjoying a newly found (19) , and many companies are providing special exercise (20) for their employees to use during the work day.

单选题1 Today cognitive theorists empirically study the impact of feelings on cognitive proces ses such as memory and judgment and also the reciprocal influence of cognition on emotion. However, evolutionary theorists view emotion as a powerful source of motiva tion—an internal communication that something must be done. For example, when people are threatened, they feel fear, which in turn leads them to deal with the threatening situa tion through either fight or flight. Emotions and drives may also operate in tandem to moti vate action, as when excitement accompanies sexual arousal. From an evolutionary per spective, different emotions serve different functions. Fear facilitates flight in the face of danger; disgust prevents ingestion of potentially toxic substances such as rotting meat. An emotion that is less well understood is jealousy. Why do people become jealous in intimate sexual relationships? One series of studies tested evolutionary hypotheses about differences in the concerns men and women have about their partners' fidelity. Since fe males can have only a limited number of children during their lifetimes, to maximize their reproductive success they should be motivated to form relationships with males who have resources and will contribute them to their offspring. Indeed, cross-cultural evidence dem onstrates that one of the main mate selection criteria used by females around the world is male resources. From a female's point of view, then, infidelity accompanied by emotional commitment to the other woman is a major threat to resources. A man unlikely to divert re sources from his mate and her offspring to a casual fling, but the risk increases dramatical ly if he becomes emotionally involved and perhaps considers switching long-term partners. Hence, a woman's jealousy would be expected to focus on her mate's emotional commitment to another female. For males, the situation is different. If a male commits himself to an exclusive rela tionship with a female, he must be certain that the offspring in whom he is investing are his own. Since he cannot be sure of paternity, the best he can do is to prevent his mate from copulating with any other males. In males, then, jealousy would be expected to focus less on the female's emotional commitment or resources and more on her tendency to give other males sexual access. Indeed, in species ranging from insects to humans, males take extreme measures to prevent other males from inseminating their mates. In humans, male sexual jealousy is the leading cause of homicides and of spouse battering cross-culturally.

单选题Specialization can be seen as a response to the problem of an increasing accumulation of scientific knowledge. By splitting up the subject matter into smaller units, one man could continue to handle the information and use it as the basis for further research. But specialization was only one of a series of related developments in science affecting the process of communication. Another was the growing professionalisation of scientific activity. No clear-cut distinction can be drawn between professionals and amateurs in science: exceptions can be found to any rule. Nevertheless, the word "amateur" does carry a connotation that the person concerned is not fully integrated into the scientific community and, in particular, may not fully share its values. The growth of specialization in the nineteenth century, with its consequent requirement of a longer, more complex training, implied greater problems for amateur participation in science. The trend was naturally most obvious in those areas of science based especially on a mathematical or laboratory training, and can be illustrated in terms of the development of geology in the United Kingdom. A comparison of British geological publications over the last century and a half reveals not simply an increasing emphasis on the primacy of research, but also a changing definition of what constitutes an acceptable research paper. Thus, in the nineteenth century, local geological studies represented worthwhile research in their own right; but, in the twentieth century, local studies have increasingly become acceptable to professionals only if they incorporate, and reflect on, the wider geological picture. Amateurs, on the other hand, have continued to pursue local studies in the old way. The overall result has been to make entrance to professional geological journals harder for amateurs, a result that has been reinforced by the widespread introduction of refereeing, first by national journals in the nineteenth century and then by several local geological journals in the twentieth century. As a logical consequence of this development, separate journals have now appeared aimed mainly towards either professional or amateur readership. A rather similar process of differentiation has led to professional geologists coming together nationally within one or two specific societies, whereas the amateurs have tended either to remain in local societies or to come together nationally in a different way. Although the process of professionalisation and specialization was already well under way in British geology during the nineteenth century, its full consequences were thus delayed until the twentieth century. In science generally, however, the nineteenth century must be reckoned as the crucial period for this change in the structure of science.

单选题Hurricanes are violent storms that cause millions of dollars in property damage and take many lives. They can be extremely dangerous, and too often people underestimate their fury. Hurricanes normally originate as a small area of thunderstorms over the Atlantic Ocean west of the Cape Verde Islands during August or September. For several days the area of the storm increases and the air pressure falls slowly. A center of low pressure forms, and winds begin to whirl around it. It is blown westward, increasing in size and strength. Hurricane hunters then fly out to the storm in order to determine its size and intensity and to track its direction. They drop instruments for recording temperature, air pressure, and humidity (湿度), into the storm. They also look at the size of waves on the ocean, the clouds, and the eye of the storm. The eye is a region of relative calm and clear skies in the center of the hurricane. People often lose their lives by leaving shelter when the eye has arrived, only to be caught in tremendous winds again when the eye has passed. Once the forecasters have determined that it is likely the hurricane will reach shore, they issue a hurricane watch for a large, general area that may be in the path of the storm. Later, when the probable point of landfall is clearer, they will issue a hurricane warning for a somewhat more limited area. People in these areas are wise to stock up on nonperishable foods, flash light and radio batteries, candles, and other items they may need if electricity and water are not available after the storm. They should also try to hurricane-proof their houses by bringing in light-weight furniture and other items from outside and covering windows. People living in low- lying areas are wise to evacuate their houses because of the storm surge, which is a large rush of water that may come ashore with the storm. Hurricanes generally lose power slowly while traveling over land, but many move out to sea, gather up force again, and return to land. As they move toward the north, they generally lose their identity as hurricanes.

单选题With the US economy slowing down, layoffs are everywhere. No industry is spared. If you end up having to start over, in addition to starting your job search, there are several things you should take care of to make your transition a smooth one. First and foremost, clear up any misunderstanding about how and why you left your last job with your ex-boss. Whether you left voluntarily, were fired or were laid off due to budget cutbacks, make sure you both have the same explanation. Agree on job titles accordingly. Also ask for a reference if you think your ex-boss will offer one and you trust that he or she will speak honestly about your performance. You should have a source of emergency cash that you can use in the interim. Don't panic and liquidate your stocks and bonds just yet, be optimistic in your prospects while also be more frugal than usual. You should save money on not having to dry clean work clothes so often and eating less take-out lunches. Save money by not eating out at restaurants and watch videos rather than going to the movies every weekend. Make a note of your job hunting expenses, such as career counselors' consulting fees and resume printing costs, and save the receipts. By next year's tax-filing time, you could get deductions on your job-search expense (unless you left a job willingly or was a college graduate looking for your first job). Most companies terminate your medical insurance coverage as soon as you stop working for them. But it doesn't mean you have to forgo medical coverage altogether. There is something called Consolidated Omnibus Budget Reconciliation Act (COBRA) in the United States that legally protects an ex-employee's right to stay in the company's health care plan. However, the company will stop paying your premiums, and you will have to pay out of your pocket the expenses. This is still a good option compared to no health insurance at all. Another important thing to take care of when you change jobs is your 401(k) account. A 401(k) is the retirement fund that most companies offer. It's named after section 401(k) in the Internal Revenue Service's policy documents. You put aside a percentage of your paycheck each pay period, and the money accumulated will be managed by the 401(k) fund manager your employer has hired and is invested in the stock market. You cannot withdraw money from this account until you reach this age, or you will incur penalties. When you leave a job, the money can sometimes be kept with your ex-employer for a while. It's always a good idea to compare your new employer's 401(k) plan with your old one. Every company offers different types of investment options, from overseas stocks to high-tech stocks and everything in between. If you do want to transfer the account to your new employer, you need to go to the human resources department and ask for forms that help you make the transition. Don't forget to ask for job leads from your ex-coworkers. Even if you are leaving for a job in another industry, you never know what people they happen to know that can help with your job search. Keep in touch with the friends you have made at your old job. Remember to anchor yourself to people, not institutions, and you will find that any transition is made easier.
