问题 When a machine analyses the frequencies used by a particular voice and draws a graph of them, sound is electronically _________ into a pattern of lines.
选项 A、contrived
B、converted
C、magnified
D、manifested
答案B
解析 动词辨义。contrive意为“谋划，策划”，如：He contrived a new machine for flying．(他设计了一种新式飞行器。)convert 意为“转变，转化”，如：That building has been converted into a school．(那座楼房改成学校了。)magnify 意为“放大，扩大”，如：This microscope magnifies an object l00，000 times．(这个显微镜能把物体放大10万倍。) manifest 意为“显示，表明”，如：He doesn’t manifest much interest in his studies．(他对学业没多大兴趣。)根据常识，本句中是指声音转化成曲线的形式表现出来，故选B)。
