What is the main topic of the passage? [br]
Although I think the United States generally has an excellent system of transportation, I do not 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, the 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. Moreover, airplanes use a lot of their fuel just getting into the air. [15]They simply are not fuel efficient on short trips. 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. [16] Maglevs will not actually ride on the tracks, but will fly above tracks that are magnetically activated. [17] This will save wear and tear on the tracks. These trains will be able to go faster than 150 miles an hour. At that speed, conventional trains have trouble staying on the tracks. [14] 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
短文中说,磁悬浮列车实际并不是在轨道上(on the tracks)行驶,而是悬浮在磁力驱动的轨道上方(above tracks),C项把above同义替换成over,故为正确答案。
