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。
