问题 The microphone makes the voice sound louder because it concentrates sound waves in one direction and keeps them from______in all directions.

选项 A、interfering
B、dispersing
C、spreading
D、distracting

答案 D

解析动词词义辨析。keep sb．from doing sth．阻止某人做某事，根据句意，这里应该是“聚光，防止光线向四面八方发散”的意思。disperse一般指云的散开；spread一般指消息的散布；distract可以指光的“分散”。故答案为D。
