问题 Maglev trains are comparable to airplanes in revolutionizing the transportation.
Japanese maglev trains are different from German ones primarily in ______.
选项
答案electromagnets
解析 第2个小标题Electrodynamic Suspension(EDS)部分的第1段第2句：The key difference between Japanese and German maglev trains is that the Japanese trains use super-cooled，superconducting electromagnets．空白处需要名词性成分。根据原文，德、日磁悬浮列车最关键的不同在于日本的磁悬浮列车使用了super-cooled， superconducting electromagnets，也就是说，德国的磁悬浮列车也用了electromagnets，但并不是日本的那一种。而题目考查的是在什么方面不同，故答案为electromagnets。
