Every year television stations receive hundreds of complaints about, the loudness of adver

tisements. 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？

The sensation of sound involves a variety of factors in addition to its peak level. Advertisers are skilful 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.

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(听觉的) 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 vowel(元音) 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.

According to the passage, the maximum intensity of sound coming from commercials ______.

A．does not exceed that of programs

B．is greater than that of programs

C．varies over a large range than that of programs

D．is less than that of programs

The history of English is conventionally, if perhaps too neatly, divided into three pe

riods usually called Old (or Anglo-Saxon) English, Middle English, and Modern English.The earliest period begins with the migration of certain Germanic tribes from the continent to Britain in the fifth century A.D., though no records of their language survive from before the seventh century, and it continues until the end of the eleventh century or a bit later.By that time, Latin, Old Norse (the language of the Viking invaders), and especially the Anglo-Norman French of the dominant class after the Norman Conquest in 1066 had begun to have a substantial impact on the vocabulary, and the well-developed inflectional(词尾变化的)system that typify the grammar of Old English had began to break down.

The period of Middle English extends roughly from the twelfth century through the fifteenth.The influence of French(and Latin,often by way of French)upon the vocabulary continued throughout the period,the loss of some inflections and the reduction of others accelerate, and many changes took place within the grammatical systems of the language.A typical prose passage, especially one from the later part of the period, will not have such a foreign look to us as the prose of Old English, but it will not be mistaken for contemporary writing either.

The period of Modern English extends from the sixteenth century to our own day.The early part of this period saw the completion of a revolution in vowel distribution that had began in late Middle English and that effectively brought the language to something resembling its present pattern.Other important early developments include the stabilizing effect on spelling of the printing press and the beginning of the direct influence of Latin, and to a lesser extent.Greel pm the vocabulary.Later, as English came into contact with other cultures around the world and distinctive dialects of English developed in the many areas which Britain had colonized, numerous other languages made small but interesting contributions to our word-stock.

1.The earliest writing record of English available to us started_____.

A.from the seventh century

B.from the fifth century

C.from the twelfth century

D.from the ninth century

2.What is the main features of the grammar of Old English？()

A.The influence of Latin

B.A revolution in vowel distribution

C.A well-developed inflectional system

D.Loss of some inflection

3.What can be inferred from the passage？()

A.Even an educated person cannot read old English without special training
