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)。
