passage one m eGk][1!
P' w*q
every year television stations receive hundreds of complaints about the loudness of advertisements. however, federal rules forbid the practice of making ads louder than the programming. in addition, television stations always operate at the highest sound level allowed for reasons of efficiency. according to one nbc executive, no difference exists in the peak sound level of ads and programming. given this information, why do commercials sound so loud? j9*U3 `s
iPx ">
dowW/ZPL
the sensation of sound involves a variety of factors in addition to its peak level. advertisers are skillful at creating the impression of loudness through their expert use of such factors. one major contributor to the perceived loudness of commercials is that much less variation in sound level occurs during a commercial. in regular programming the intensity of sound varies over a large range. however, sound levels in commercials tend to stay at or near peak levels. 8QHDf; c
other “ tricks of the trade ” are also used. because low – frequency sounds can mask higher frequency sounds, advertisers filter out any noises that may drown out the primary message. in addition, the human voice has more auditory(的) impact in the middle frequency ranges.advertisers electronically vary voice sounds so that they stay within such a frequency band. another approach is to write the script so that lots of consonants(辅音) are used, because people are more aware of consonants than vo音) sounds. finally, advertisers try to begin commercials with sounds that are highly different from those of the programming within which the commercial is buried. because people become adapted to the type of sounds coming from programming, a dramatic change in sound quality draws viewer attention. for example, notice how many commercials begin with a cheerful song of some type.

the attention – getting property of commercials can be seen by observing one – to two – year – old children who happen to be playing around a television set. they may totally ignore the programming. however, when a commercial comes on, their attention is immediately drawn to it because of its dramatic sound quality.

passage two . 3L^}c*~
Sn~'EYg
in the united states, the need to protect plant and animal species has become a highly controversial and sharply political issue since the passage of the endangered species act in 1973. the act, designed to protect species’ living areas, and policies that preserve land and forests compete with economic interests. in the 1990’s, for example, the woodcutters in the western united states were challenged legally in their attempt to cut trees for timber in the cascade mountains. the challenge was mounted to protect the endangered spotted owl(鹰), whose remaining population occupies these forests and requires the intact, ancient forest for survival. the problematic situation set the interests of environmentalists against those of corporations and of individuals who stood to lose jobs. after months of debate and legal battles, the fate of the woodcutters – and the owls – was still undecided in mid – 1992. 18 8RA(<{
similar tensions exist between the developed and the developing nations. many people in industrialized nations, for example, believe that developing nations in tropical regions should do more to protect their rain forests and other natural areas. but the developing countries may be impoverished(困), with populations growing so rapidly that using the land is a means to temporarily avoid worsening poverty and starvation. 5'Un] 6?p
S&)\g)(?
many of the changes to earth that concern scientists have the potential to rob the planet of its biological richness. the destruction of earth’s ozone layer(臭氧层), for example, could contribute to the general process of impoverishment by allowing ultra – violet rays to harm plants and animals. and global warming could wipe out species unable to quickly adapt to changing climates. clearly, protecting earth’s biological diversity is a complex problem. but solutions to humanity’s current problems will come only through coordinated international efforts to control human population, stabilize the composition of the atmosphere, and preserve intact earth’s complex web of life. }~-!yBHP4
