问题 Maglev trains are comparable to airplanes in revolutionizing the transportation.
By using the Inductrack, the train will slow down and finally rest on ______ when the power is off.
选项
答案its auxiliary wheels
解析 第2个小标题Electrodynamic Suspension(EDS)部分的第3段最后一句：If the power fails，the train call slow down gradually and stop on its auxiliary wheels。空白处需要名词性成分。题目中的when状语从句表达了原文中If从句的内容，而rest on与原文中的stop on意思一致，故答案为池auxiliary wheels。
