问题 These results must be accurate, because all the calculations have been done by an________computer.

选项 A、electric
B、electronic
C、electrical
D、electricity

答案B

解析单词题。本题考查四个近义词的辨析。electric adj. 为“电的，用电的，带电的”指任何电动的或发电的装置，被修饰的物体本身可带电，如：electric light；electrical为“电的，与电有关的，电气科学的”，指与电有关的事物，被修饰的词本身并不能带电，如：electrical engineer；electronic是电子的，和电子有关的，如，electronic book；electricity n. 电力，电流。根据句意，电子计算机，应该选择electronic。本句意：这些结果必须是准确的，因为所有的计算都是电子计算机完成的。
