选项
A、relieved
B、converted
C、magnified
D、burst
答案
B
解析
动词辨义。convert意为“转变,转换”,如:Heat converts water into steam.(热使水变为蒸汽。)re lieve意为“减轻,解除”,如:This remedy will relieve the pain.(这种治疗将会减轻痛苦。)magnify意为“放大”,如:The microscope magnified the object one hundred times.(显微镜把物体放大了一百倍。)burst意为“爆炸,破裂”,如:The boiler burnt.(锅炉爆炸了。)根据题意,声音被转化为线状模式,故选B)。
