strongest cultural influence[解析] 1-20Television is the single strongest cultural influence on American life and the widely recognized lowest common denominator. More homes have televisions than indoor plumbing and the average child spends more time watching television that he or she does in the classroom.Television defines a reality of its own; news that isn t covered on television didn t happen and television-only events provoke nationwide reactions.Daytime shows lean towards endless soap operas with plots that revolve around infidelity and medical crises, and talk shows in which hosts prod their guest m reveal personal details no sane person would want to make public.The American passion for getting something for nothing reaches a frenzy in evening game shows. Another evening staple is the hard-boiled investigative show, which dwells on lurid topics such as body-snatching, drug-dealing, and juvenile prostitution. The latest development in this kind of program is the real-life crime show, on which cameramen follow the police around for an evening and film them making arrest.Television reached its highest level, or perhaps more accurately, its lowest, with the introduction of cable, which provides more than 50 channels of programs. Specialized programs include The Weather Channel, 24 hours a day of forecasts; Music Television (MTV) and its country music and soul music imitators; C-span, which shows the U. S congress in session and is widely applied as something that makes you sleep, and Courtroom Television, which allows viewers to shriek at the television judge the way sports fans might shriek at a referee.On American television, few topics are considered cultural minefields. Turn on a television any afternoon and you can see people discussing, in intimate details, before millions of viewers, topics natives of other nations wouldn t whisper about in the dark.Faced with such unabashed exhibitionism, one is tempted m scream, Is nothing sacred The answer, of course, is Well, actually, No. Not on television, anyway.
