求 !帮忙翻译这段话!
Light travels at a speed which is about a million times faster than the speed of sound. In one second, light travels about 300,OOOkm,but sound travels only 344m. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears.

光能够以音速将近一百万倍的速度行进.一秒钟之内,光可以行进300,000公里,但是声音只能传播344米.通过观察赛跑的起泡,你可以对这种差异有个直观的印象.假如你在距离发令员（起跑线位置）一定距离之外,那么你会先看到发令枪冒烟,然后枪声才会传到你的耳朵里.
