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、relieved
B、converted

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)。
