四级Although no form of matter yet discovered moves as fast as or faster than light, scientific experiments have already confirmed that accelerated motion causes a traveler's time to be stretched.

尽管目前还没有发现任何一种物质的运动速度比光速快，但科学实验已经证实，加速运动会延长旅行者的时间。

六级Unfortunately for them ( ' , and often the taxpayers), our energy systems are a bit like an aircraft carrier: they are unbelievably expensive, they are built to last for a very long time, they have a huge amount of inertia ( ' , meaning it takes a lot of energy to set them moving), and they have a lot of momentum once they are set in motion.

不幸的是，对他们（通常是纳税人）来说，我们的能源系统有点像一艘航空母舰：它们的价格高得令人难以置信，它们的建造寿命很长，它们有巨大的惯性（这意味着需要大量的能量才能使它们移动），一旦它们启动，它们就有很大的动力。
