What is the topic of the talk? [br]
Although I think the United States generally has an excellent system of transportation, I don’t think that it does a good job of transporting people between cities that are only a few hundred miles apart. A person commuting between Detroit and Chicago or between San Francisco and Los Angeles, so-called strip cities, may spend only a relatively short time in the air while spending several hours getting to and from the airport. This situation makes flying almost as time-consuming as driving. High speed trains may be an answer. One fairly new proposal for such a train is for something called a MAGLEV, meaning a magnetically levitated train. Maglevs will not actually ride on the tracks that are magnetically activated. This will save wear and tear on the tracks. These trains will be able to go faster than 150 miles per hour. At that speed conventional trains have trouble staying on the tracks. As you can see, Maglevs offer exciting possibilities for the future.
选项
A、It uses nuclear energy.
B、It rests on a cushion of pressurized air.
C、It flies over magnetically activated tracks.
D、It uses a device similar to a jet engine.
答案
C
解析
Maglev是一种磁悬浮列车,它并不像传统的火车那样行驶在轨道上,由(Maglev means amagnetically levitated train…not actually ride on the tracks that are magnetically activated)可知C为正确答案。
