47、e the letter of your choice on your answer sheet. passage 1 the people who lived in rome 2,000 years ago were already complaining about the noise in their city. they couldnt sleep, they said, with all that traffic in the streets. for them, noise was merely a disturbance. for us it has become a real

48、danger. we know that the sounds of an averagecity are loud enough to cause serious damage to the inhabitants hearingin the united states, one person out of twenty has suffered some hearing loss. and all over the world the situation is getting worse all the time, since noise increases with the popula

49、tion.noise has also increased enormously in the 20th century with the development of machines. we live surrounded by loud planes, trucks, motorcycles, buses, electric tools, radios, pneumatic drillsthat roar day and night up to 90 or 100 decibels. the decibel is the unit used to measure the loudness

50、 of sound. a normal conversation reaches 55 decibels, thunder roars at 70 decibels, a jet plane goes to 100 decibels and more, and an ordinary subway train, approaching the station, can be twice as loud as the loudest jet. the average discotheque reaches around 118 decibels. at 120 decibels the ear

51、stops hearing sound, and pain starts.unfortunately, the human ear does not judge clearly the degree of loudness of a noise. a sound ten decibels louder than another one is felt as twice as loud, when in fact it is ten times louder. since we cannot measure the increase or decrease of noise, we never

52、know to what danger we are exposed.but it is not only our hearing that is threatened. it has been established that loud noises, over a period of time, cause loss of sleep, anger, and many mental and physical problems. such problems have been observed among factory workers, prisoners in large prisons

53、, and people who drive heavy trucks, operate pneumatic drills, or go frequently to rock-and-roll concerts.is there a solution? we do know how to build quieter machines, if the public wants them. but merchants point out that people who buy motorcycles, for instance, prefer the loudest ones because th

54、ey sound more powerful. some cities are trying to enforce more strictly their anti-noise laws. in memphis automobilists are fined fifty dollars for honking; they may lose their right to drive if they do it again. people who carry noisy radios in public places may lose them if they are caught with th

55、em.actually, it will take everybodys efforts to keep city noises from increasing. even so, say the experts, in twenty years the cities will be twice as loud as they are today because of the growth of the population. the inhabitants will have to shout to be heard at the dinner table. unless, of cours
