单选题Until last spring, Nia Parker and the other kids in her neighborhood commuted to school on Bus 59. But as fuel prices rose, the school district needed to find a way to cut its transportation costs. So the schools busing company redrew its route map, eliminating Nia's bus altogether. Now Nia and her neighbors travel the half mile to school via a "walking school bus" — a group of kids, supervised by an adult or two, who make the walk together. Like the rest of us, school districts are feeling pinched by rising fuel costs — and finding new ways to adapt. The price of diesel fuel has gone up 34 percent in the past two years. For the typical American school district, bus bills total 5 percent of the budget. As administrators look to trim, busing is an inviting target, since it doesn't affect classroom instruction(or test scores). More than one third of American school administrators have eliminated bus stops or routes in order to stay within budget. Many parents are delighted to see their kids walking to school, partly because many did so themselves: according to a 1969 survey, nearly half of school kids walked or biked to school, compared with only 16 percent in 2001. Modern parents have been unwilling to let kids walk to school for fear of traffic, crime or simple bullying, but with organized adult supervision, those concerns have diminished. Schools and busing companies are finding other ways to save. In rural areas where busing is a must, some schools have even chosen four-day school weeks. Busing companies instruct drivers to eliminate extra stops from routes and to turn off engine while idling. They are also using computer software to determine the most fuel-efficient routes, which aren't always the shortest ones. There could be downsides, however, to the busing cutbacks. If every formerly bused student begins walking to school, it's an environmental win — but if too many of their parents decide to drive them instead, the overall carbon footprint can grow. Replacing buses with many more parent — driven cars can also increase safety risks: A 2002 report concluded students are 13 times safer on a school bus than in a passenger car, since buses have fewer accidents and withstand them better due to their size. And some students complain about the long morning hikes, particularly when the route contains a really big hill.

单选题Classified Advertising is that advertising which is grouped in certain sections of the paper and is thus distinguished from display advertising. Such groupings as "Help Wanted", "Real Estate", "Lost and Found" are made, the rate charged being less than that for display advertising. Classified advertisements are a convenience to the reader and a saving to the advertiser. The reader who is interested in a particular kind of advertisement finds all advertisements of that type grouped for him. The advertiser may, on this account, use a very small advertisement that would be lost if it were placed among larger advertisements in the paper. It is evident that the reader approaches the classified advertisement in a different frame of mind from that in which he approaches the other advertisements in the paper. He turns to a page of classified advertisements to search for the particular advertisement that will meet his needs. As his attention is voluntary, the advertiser does not need to rely to much extent on display type to get the reader's attention. Formerly all classified advertisements were of the same size and did not have display type. With the increase in the number of such advertisements, however, each advertiser within a certain group is vying with others in the same group for the reader's attention. In many cases the result has been an increase in the size of the space used and the addition of headlines and pictures. In that way the classified advertisement has in reality become a display advertisement. This is particularly true of real-estate advertising.

单选题3 The Internet is a global network that connects other computer networks, together with software and protocols for controlling the movement of data. The Internet, often re ferred to as "the Net", was initiated in 1969 by a group of universities and private re search groups funded by the US Department of Defense. It now covers almost every country in the world. Its organization is informal and deliberately nonpolitical; its controllers tend to concentrate on technical aspects rather than on administrative control. The Internet offers users a number of basic services including data transfer, electronic mail, and the ability to access information in remote databases. A notable feature is the ex istence of user groups, which allow people to exchange information and debate specific subjects of interest. In addition, there are a number of high-level services. For example, MBONE allows the transmission of messages to more than one destination. It is used in videoconferencing. The World Wide Web, known as "the Web", is another high level In- ternet service, developed in the 1990s in Geneva. It is a service for distributing multimedia information, including graphics, pictures, sounds, and video as well as text. A feature of the World Wide Web is that it allows links to other related documents elsewhere on the In ternet. Documents for publication on the Web are presented in a form known as HTML (hypertext mark up language). This allows a specification of the page layout and typogra phy as it will appear on the screen. It also allows the inclusion of active links to other docu ments. Generally, these appear on the screen display as highlighted text or as additional icons. Typically, the user can use a mouse to "click" on one of these points to load and view a related document. Many commercial and public organizations now have their own Web site (specified by an address code) and publish a "home page", giving information about the organization. Up to the mid-1990s, the major users of the Internet were academic and research or ganizations. This has begun to change rapidly with individual home users linking in through commercial access providers and with a growing interest by companies in using the Internet for publicity, saies, and as a medium for electronic publishing. At the same time, there are problems with the flow of information across national borders, bringing in debates about copyright protection, data protection, the publication of pornography, and ulti mately political control and censorship.

单选题Prominently displayed on the front page of the New York Times is the company motto: "All the News That's Fit to Print." No form of mass media can carry every newsworthy event; all are constrained by costs and availability of space and time. For instance, the average daily newspaper fills approximately 62 percent of its space with advertising, leaving a mere 38 percent for news accounts, along with human interest stories, and pure entertainment features. Contrary to the mirror-to-society myth, news is not simply out there; it must be picked from a multitude of happenings, What then is news? Perhaps the best explanation is that "news is what reporters, editors, and producers decide is news." Although the basis of news judgment often seems vague and unarticulated, Doris Graber has identified five criteria most often used in selecting stories. * To qualify as news the story must have a high impact on the audience, that is, the events covered must be relevant to people's lives. Events in the Middle East, for example, are news when they have a measurable effect on American hostages there or on the supply of oil at home. * Larry Speakes, who served as deputy press secretary to former President Ronald Reagan, once noted that no one pays attention when one hundred members of Congress come out of a White House meeting and say that the president's program is great. "But if one says it stinks, that's news." * Familiarity is also an element of newsworthiness. Approximately 85 percent of the domestic news stories covered by television and news magazines involve well-known people-mostly those holding official positions. Unknown people are most newsworthy as victims of crime or natural disasters. * Local events are more newsworthy than those far away. In a nation linked by instant communications, however, close to home may also include such familiar locations as Washington, D. C. , and Wall Street. * Stories must be timely and novel to capture the attention of the media. As a former editor of the old New York Sun put it, "When a dog bites a man, that is not news, because it happens often. But if a man bites a dog, that is news." Reporters rely almost exclusively on interviewing and only occasionally on the reading of documents. The dependence on the interview results partly from the need to personalize the news—especially in television journalism, with its demand for visuals. The fact that most reporters find document analysis dull and boring also increases their dependence on interviews. Whatever the cause, the result is a bias in favor of those willing and able to talk. These criteria have little to do with the intrinsic importance of news stories and stress mainly ways of keeping me audience interested. Because media outlets make their profit from the advertising, they must keep their ratings or circulations high. This concern for audience appeal has an impact on the way politics is conducted in the United States.
