问题 A sound which is capable of distinguishing one word in meaning from another in a given language is a______.

选项 A、phone
B、phoneme
C、allophone
D、allomorph

答案B

解析 考查语音学中概念的区分。phone“音素”,phoneme“音位”,allophone“音位变体”,allomorph“词素变体”。音位是语音系统中能够区别词义的基本语音单位,音位定义的要点是区别意义。音位变体为同一音位在不同环境中表现出来的两个或多个不同的语音形式。词素变体是词素在不同情况下的不同形式,侧重的是从语法结构角度研究语素。故选B。
