回答题A few minutes ago, walking back from lunch, I started to cross the street when I heard the sound of a coin dropping．It wasn't much but, as I turned, my eyes caught the heads of several other people turning too．A woman had dropped what appeared to be a dime．The tinkling sound of a coin dropping on pavement is an attention-getter．It can be nothing more than a penny．Whatever the coin is, no one ignores the sound of it．It got me thinking aboutsounds again．We are besieged(包围) by so many sounds that attract the most attention．People in New YorkCity seldom turn to look when a fire engine, a police car or an ambulance comes screaming along the street．When I'm in New York, I'm a New Yorker．I don't turn either．Like the natives．At home in my little town in Connecticut, it's different．The distant wail of a police ear, anemergency vehicle or a fire siren brings me to my feet if I'm seated and brings me to the window if I'm in bed．It's the quietest sounds that have most effect on us, not the loudest．In the middle of the night, Ican hear a dripping tap a hundred yards away through three closed doors．I've been hearing little creaking noises and sounds which my imagination turns into footsteps in the middle of the night for twenty-five years in our house．How come I never hear those sounds in the daytime?
