单选题
The noise was so ______ that only those with excellent hearing were
aware of it.
A. soft
B. faint
C. quiet
D. inaudible
【正确答案】
B
【答案解析】soft意为“柔软的”,指易于塑造、切割或加工的;faint意为“微弱的”,指声音不大的;quiet意为“安静的”,指不制造噪声的;inaudible意为“听不到的”,指听不见声音的。所填之词的主语是noise(噪声),根据后面的with excellent hearing were aware of it(听力很好的人才注意到)可知,应该选用faint。
