man's first real invention ,and one of the most important inventions in history ,was the wheel.all transportation and every machine in the world depends on it .the wheel is the simplest yet perhaps the most remarkable of all inventions,because there are no wheel in nature-no living thing was ever created with the wheel?perhaps some early hunters found that they could roll the dead body of a heavy animal through the forest on logs more easily than they could carry it .however ,the logs themselves weighed a lot.it must have taken a great prehistoric thinker to imagine two thin slices of log connected at the logs did,yet be much lighter and easier to handle.thus the wheel and axle came in to being ,and with them the first carts.

人类第一次真正的发明,也是在历史上最重要的一项发明,就是轮子.世界上所有的交通工具和每一台机械都得依靠他.轮子是最简单但是可能是所有发明中最非凡的.因为自然界中没有轮子,也没有任何生物被创造时便有轮子.可能一些早期的捕猎者就发现,相对搬运,他们能更轻松的通过圆木滚动大型动物的尸体穿越森林.然而圆木本身却很沉重,而它一定让史前的一位伟大的思想者设想出,两片薄的圆木片用圆木连接起来,这样立刻就会变得更轻也更容易操纵.如此一来便形成了轮子与轮轴,和他们一起则出现了第一辆两轮推车.
