问题 Maglev trains are comparable to airplanes in revolutionizing the transportation. [br] 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。
