单选题Walking is Britain's most popular outdoor ______ and is the most pleasant and satisfying way of discovering the countryside.

单选题With the start of BBC World Service Television, millions of viewers in Asia and America can now watch the Corporation"s news coverage, as well as listen to it. And of course in Britain listeners and viewers can tune in to two BBC television channels, five BBC national radio services and dozens of local radio station. They are brought sport, comedy, drama, music, news and current affairs, education, religion, parliamentary coverage, children"s programmes and films for an annual licence fee of 83 pounds per household. It is a remarkable record, stretching back over 70 years—yet the BBC"s future is now in doubt. The Corporation will survive as a publicly-funded broadcasting organization, at least for the time being, but its role, its size and its programmes are now the subject of a nation-wide debate in Britain. The debate was launched by the Government, which invited anyone with an opinion of the BBC—including ordinary listeners and viewers—to say what was good or bad about the Corporation, and even whether they thought it was worth keeping. The reason for its inquiry is that the BBC"s royal charter runs out in 1996 and it must decide whether to keep the organization as it is, or to make changes. Defenders of the Corporation—of whom there are many—are fond of quoting the American slogan "If it ain"t broke, don"t fix it." The BBC "ain"t broke", they say, by which they mean it is not broken (as distinct from the word "broke", meaning having no money), so why bother to change it? Yet the BBC will have to change, because the broadcasting world around it is changing. The commercial TV channels—TV and Channel 4—were required by the Thatcher Government"s Broadcasting Act to become more commercial, competing with each other for advertisers, and cutting costs and jobs. But it is the arrival of new satellite channels—funded partly by advertising and partly by viewers" subscriptions—which will bring about the biggest changes in the long term.

单选题{{B}}Passage Four{{/B}} Television is one of today's most powerful and widespread means of mass communication. It directly influences our lives on both a short and long-term basis; it brings worldwide situations into our homes; it affords extensive opportunities for acquiring higher education; and it performs these tasks in a convenient yet effective manner. We are all aware of the popularly accepted applications of television, particularly those relative to entertainment and news broadcasting. Television, however, has also been a vital link in unmanned deep space exploration (such as the Voyager I and Ⅱ missions), in providing visions from hazardous areas (such as proximity to radioactive materials or environments) in underwater research, in viewing storms moving across a metropolitan area (the camera being placed in a weather-protective enclosure near the top of a tower), etc. The earth's weather satellites also use television cameras for vie- wing cloud cover and movements from 20,000 miles in space. Infrared filters are used for night views, and several systems include a spinning mirror arrangement to permit wide-area views from the camera. Realizing the unlimited applications for today's television, one may thus logically ponder the true benefits of confining most of our video activities to the mass-entertainment field. Conventional television broadcasting within the United States centres around free enterprise and public ownership. This requires funding by commercial sponsors, and thus functions in a revenue-producing business manner. Television in USSR-subjected areas, conversely, is a government-owned and maintained arrangement. While such arrangements eliminate the need for commercial sponsorship, it also has the possibility of limiting the type of programs available to viewers (a number of purely entertainment programs similar to the classic "Bewitched", however, have been seen on these government -controlled networks. All isn't as gray and dismal as the uninformed might unnecessarily visualize). A highly modified form of television called Slow-Scan TV is presently being used by many Amateur Radio operators to provide direct visual communications with almost any area of the world. This unique visual mode recently allowed people on the tiny South Pacific country of Pitcairn Island to view, for the first time in their lives, distant areas and people of the world. The chief radio Amateur and communications officer of Pitcairn, incidentally, is the legendary Tom Christian-great, great grandson of Tom Christian of "Mutiny on the Bounty" fame. Radio Amateurs in many lands worked together for several months establishing visual capabilities. The results have proven spectacular, yet the visual capabilities have only been used for health education, or welfare purposes. Commercial TV is still unknown to natives of that tiny country. Numerous other forms of television and visual communication, have also been used on a semi-restricted basis. This indicates the many untapped areas of video and television which may soon be exploited on a more widespread basis. The old clich of a picture being worth a thousand words truly has merit.

单选题{{B}}Passage 4{{/B}} "Sloganeering" did not originate in the 1960s. The term has a rich history. It originated from the Gaelic word slaughgharim, which signified a "host-shout." "war cry," or "gathering word or phrase of one of the old Highland clans; hence the shout or battle cry of soldiers in the field." English-speaking people began using the term by 1704. The term at the time meant "the distinctive note, phrase, or cry of any person or body of persons." Slogans were common throughout the European continent during the middle ages, and they were utilized primly as "passwords to insure proper recognition of individuals at night or in the confusion of battle." The American revolutionary rhetoric would not have been the same without "the Boston Massacre," "the Boston Tea Party," "the shot heard around the world," and shouts of "no taxation without representation." Slogans operate in society as "social symbols" and, as such, their intended or perceived meaning may be difficult to grasp and their impact or stimulation may differ between and among individuals and groups. Because slogans may operate as "significant symbols" or as key words that have a standard meaning in a group, they serve both expressive and persuasive functions. Harold Lasswell recognized that the influencing of collective attitudes is possible by the manipulation of significant symbols such as slogans. He believed that a verbal Symbol might evoke a desired reaction or organize collective attitudes around a symbol. Murray Edelman writes that "to the political scientist patterning or consistency in the context in which specific groups of individuals use symbols is crucial, for only through such patterning do common political meaning and claims arise." Thus, the slogans a group uses to evoke specific responses may provide us with an index for the group's norm, values, and conceptual rationale for its claims. Slogans are so pervasive in today's society that it is easy to underestimate their persuasive power. They have grown in significance because of the medium of television and the advertising industry. Television, in addition to being the major advertising medium, has altered the nature of human interaction. Political images are less personal and shorter. They function as summaries and conclusions rather than bases for public interaction and debate. The style of presentation in television is more emotional, but the content is less complex or ideological. In short, slogans work well on television. The advertising industry has made a science of sloganeering. Today, communication itself is a problem because we live in an "overcommunicated" society. Advertisers have discovered that it is easier to link product attributes to existing beliefs, ideas, goals, and desires of the consumer rather than to change them. Thus, to say that a cookie tastes "homemade" or is as good as "Mom used to make" does not tell us if the cookie is good or bad, hard or soft, but simply evokes the fond memories of Mother's baking. Advertisers, then, are more successful if they present a product in a way that capitalizes on established beliefs or expectations of the consumer. Slogans do this well by crystallizing in a few words the key idea or theme one wants to associate with an issue, group, product, or event. "Sloganeering" has become institutionalized as a virtual art form, and an advertising agency may spend months testing and creating the right slogan for a product or a person. Slogans have a number of attributes that enhance their persuasive potential for social movements. They are unique and readily identifiable with a specific social movement or social movement organization. "Gray Power," for instance, readily identifies the movement for elderly Americans, and "Huelga" (strike in Spanish) identifies the movement to aid Mexican American field workers in the west and southwest.

单选题With the possible exception of equal rights, perhaps the most controversial issue across the United States today is the death penalty. Many argue that it is an effective deterrent (威慑) to murder, while others maintain there is no convincing evidence that the death penalty reduces the number of murders. The principal argument advanced by those opposed to the death penalty, basically, is that it is a cruel and inhuman punishment that it is the mark of a brutal society, and finally that it is of questionable effectiveness as a deterrent to crime anyway. In our opinion, the death penalty is a necessary evil. Throughout recorded history there have always been those extreme individuals in every society who were capable of terribly violent crimes such as murder. But some are more extreme than others. For example, it is one thing to take the life of another in a fit of blind rage, but quite another to coldly plot and carry out the murder of one or more people in the style of a butcher. Thus, murder, like all other crimes, is a matter of relative degree. While it could be argued with some conviction that the criminal in the first instance should be merely isolated from society, such should not be the fate of the latter type of murderer. The value of the death penalty as a deterrent to crime may be open to debate. But the overwhelming majority of citizens believe that the death penalty protects them. Their belief is reinforced by evidence which shows that the death penalty deters murder. For example, from 1954 to 1963, when the death penalty was consistently imposed in California, the murder rate remained between three and four murders for each 100,000 population. Since 1964 the death penalty has been imposed only once, and the murder rate has risen to 10.4 murders for each 100,000 population. The sharp climb in the state"s murder rate, which began when executions stopped, is no coincidence (巧合). It is convincing evidence that the death penalty does deter many murderers. If the bill reestablishing the death penalty is vetoed (否决), innocent people will be murdered—some whose lives may have been saved if the death penalty were in effect. This is literally a life or death matter. The lives of thousands of innocent people must be protected.
