Everybody’s voice is (54) . When a person’s voice is recorded by an instrument, his voice frequency spectrum (频谱) is called sound print. (55) a fingerprint, everybody’s sound print is different.

选项
A、With
B、Like
C、For
D、As
答案
B
解析
由于每个人的声音不一样,声音的频谱自然也不一样。根据常识可知,人的指纹各不相同,所以,这句话的意思是声纹和指纹一样,每个个体皆不相同。like是介词,表达了“类似,和……一样”的含义,所以此处选like,而with,for没有“相似”的含义,as能表达“像”的含义,但用法不同,所以选B。
