问题 Which of the following sets of phonetic features characterizes the English phoneme ?

选项 A、[+semi-closed, +back, -rounded]
B、[+semi-open, +back, +rounded]
C、[+closed, +back, +rounded}
D、[+open, +front, +rounded]

答案B

解析 考查语音知识。元音一般从四个方面进行描述:舌位(high,mid,low),舌头最高部位的位置(front,central,back),长度(long,short)或紧张度(tense,lax),唇的开口度(rounded,unrounded)。为半开后圆唇元音。故选B。
