问题
Maglev trains are comparable to airplanes in revolutionizing the transportation. [br] The EDS system is not perfect in that the maglev trains must ______ before leaving the ground.
选项
答案
roll on rubber tires
解析
第2个小标题Electrodynamic Suspension(EDS)部分的第2段第2句:One potential drawback in using the EDS system is that maglev trains must roll on rubber tires until they reach a liftoff speed Of about 62 mph(100 kph).空白处需要动词性成分。题目中的not perfect与原文中的one potential drawback一致。题目询问磁悬浮列车在离地前应该怎么样,故答案应该在原文must之后,答案为roll on rubber tires。
