英语翻译
When we speed along a modern highway．we rarely stop to think what it is we are riding on .To understand what a road is,we must study the ways in which people have traveled in the past.
The very first roads were really tracks beaten in the ground by wild animals in prehistoric time.People followed these winding trails because they provided an easy and quick way to get through thick forests．In time,people began to improve the paths by filling holes with earth and laying logs across soft,boggy spots．These attempts were crude,but they were the beginning of road construction．
As people began to transport goods over longer distances,they developed new ways of traveling.First they packed their wares on animals.They invented various kinds of sleds.Finally,after the invention of the wheel,they built wagons.Each advancement brought a need for better traveling routes.
Later in history,when well-traveled routes were made sturdier with rocks and stones．The path was raised above the surrounding land ,It became a “high way”.
The great civilization throughout history were also the great road builders.Roads were necessary to control and extended empires,to permit trade and travel ,and to move armies.
Most of these early roads were simply hard-packed dirt,but some were paved with stone blocks or burnt bricks.

当开着车飞驰在高速公路上时,我们很少会停下来思考脚下经过的路.要了解什么是路,就必须研究人们过去出行的方式.
第一条真正的路是史前时代的野生动物们踩出来的小道,人们通常会沿着这些弯曲小道以便快速穿过密林.随着时间的推移,他们又学会用泥土填充道路上的坑洼,在柔软的沼泽地上铺上木头.尽管这些尝试很原始,但却是道路建设的开端.
随着货物开始远距离运输,人们发明了新的运输方式.首先,他们将物品捆绑在动物身上,接着发明各种雪橇.最后车轮诞生,货车问世.这些进步带来了更佳路况的需要.
早期的道路大多是坚实的泥土,但也有一些是由石头或者砖块铺成.后来,当我们给道路加固上更坚固的岩石时,小道便高出了周围地面,成为“高速公路”.
历史上最伟大的文明之一就是道路建设.为了控制和扩张帝国以及交易往来、行动打仗,道路成为必需.
