And there's no telling where a prairie fire will stop, once it gets started.

谁也说不准一旦大火烧起来会烧到哪里。

The prairie fire was roaring now, roaring louder and louder in the screaming wind.

原大火现在正在肆虐，随着呼啸的狂风，火势越来越大。

It had either burned from a prairie fire or, more likely, it was set on fire by natives of some sort who were discontented with Lewis and Clark.

它要么是被原大火烧毁，更有可是被某种不满刘易斯和克拉克的土著人放火烧掉的。

They're called the Black Legs because the other side tried to make them retreat by starting a prairie fire so the fire would wash over them and move them back.

他们之所以被称黑腿，是因对通过燎原之火让他们撤退，这样大火就会冲刷他们并将他们赶回去。

So China can just wait for a lot of these labs in the US, in Germany, Japan, to figure out these new sparks, and then they set off the prairie fire.

所以中国可以坐等美国、德国、日本的许多实验室率先发现这些新技术的火花，然后中国再迅速将其大规模推广，掀起一场燎原之势。
