问题
A (n) ______ is a unit that is of distinctive value. It is an abstract unit, a collection of distinctive phonetic features.
选项
A、phone
B、sound
C、allophone
D、phoneme
答案
D
解析
本题考查语音学基本概念。语音学(Phonetics)研究的基本单位是音位(phoneme),音位具有区别性价值,音位是抽象的,是一组语音特征的集合,它不是一个具体的音。一个音位会在不同的语音环境中实现为具体的音,如音位/p/在语境中可实现为具体的送气和不送气音等,这种语音的细微差别可在单词spade和pay中的/p/的发音可以看出。allophone(音位变体)是音位的可测语音变体,如送气音t在top中,非送气音t在stop中,还有tt(发成d)在batter中,都属于英语音素t的变体。
