模仿文本: Well, here's another idea to cut journey times and this one is straight out of science fiction. It's a bit like a cross between the London underground and a giant gun. It involves firing a tube-shaped carriage full of people along a tunnel at twice the speed of an aeroplane. Well, it'd run between the US cities of Los Angeles and San Francisco, slashing journey times from the five hours it takes a driver today down to just 30 minutes.

译文: 这个缩短旅行时间的新创意简直就像科幻小说一样，感觉是结合了伦敦地铁和一把巨大的枪，把满载乘客的管状车厢以飞机的两倍速度沿隧道发射出去。这种新型“地铁”将会在美国洛杉矶和旧金山之间运行，全程仅需30分钟，而现在开车则需要五个小时。
