问与答

摘要

<正> 问:sound,voice,noise和tune有什么区别?答:sound,voice和tune都有“声音”的意思。但在意思和用法上却有区别。 a sound仅只是你所听到的某种声音。它是一个常用词。例:I was lying in bed late last night when suddenly I heard a sound in the next room. He heard semething unspecified in the next room but a sound. 以上两例中a sound不是具体声音,而是声响、动静。某物掉地时的sound是媒介本身,即空气的振荡。
