问题 Transportation has continued to change dramatically with each generation. The last commercial innovation was electric trains, like France’s TGV, which were first introduced in the early 1980s and are capable of reaching speeds of more than 185 miles an hour. The next trend in trains will most likely be the "maglevs," or magnetic levi-tation trains, which are designed to hover over their tracks by resting on magnetic fields and which are driven by motors with no moving parts. Once these trains are up and running, they are expected to reach speeds of more than 400 miles per hour. [br] Which of the following would most likely be found at the beginning of this passage?
选项 A、A discussion of different transportation methods that have been used throughout history
B、A statistical analysis of transportation trends in several countries
C、A series of portraits of the types of trains utilized throughout the history of the United States and Europe
D、An account of the technological challenges involved in engineering faster trains
E、An essay on historical transportation models
答案 C
解析 The best answer is C. The passage focuses solely on trains, which narrows the choices to C and D. Because the structure of the passage is historical, choice C is the best option.
