问题 The word "colonize" (Line 3, Para. 1) means ______ .
Which means are mentioned as faster means of transportation in the future?

选项 A、Cars, space planes, maglev trains.
B、Planes, maglev trains.
C、Rockets, maglev trains.
D、Space planes, maglev trains.

答案D

解析 细节题。在第三段中讲了未来更为快速的交通方式,有太空飞机“space-planes”,高速磁悬浮火车“high-speed maglev trains"。作者没有说普通的飞机将来速度会更快,也没有说汽车和火箭。所以只有D是正确的。
