Plow (6000 BC)

The domestication of animals such as oxen provided mankind with the pulling power needed to develop the first plows. They consisted of a frame holding a vertical wooden stick that was dragged through the topsoil -- and are still used in many parts of the world.

犁（公元前6000年）

馴化牛等動物為人類制造首批耕地用的犁提供了牽引力。犁由一個框架組成，框架上支撐著一根垂直的木棍，通過牛拉犁，木棍就可以劃過表層土壤。如今全球很多地區(qū)仍在使用。
