人类的成绩表现正在各个方面. 磨石取火的主要性不亚于把人类送往月球. 近前人学会利用石制东西和生火,标记灭现代社会的起头. 之后的各类发觉,例如青铜,铁,蒸汽,电能等等,使社会进一步成长并成绩了汗青.那些发现如斯主要，所以我们常按照各个期间的最新科技把人类汗青划分为如下几个期间:石器时代,青铜时代,铁器时代,等等。
Human achievements come in all shapes and sizes. Knocking two rocks together can be just as important as sending a man to the moon. When ancient humans learnt to use stone tools and make fire, it meant the beginning of modern society. Later discoveries------bronze, iron, steam, electricity, to name a few------continued the development of society and shaped history. So important were these achievements that we often divide human history into time periods named after the latest technology of the time: the Stone Age, the Bronze Age, the Iron Age and so on
人类的成绩表现正在各个方面. 敲击两块石头生火的主要性不亚于把人送往上月球. 当近前人学会利用石制东西和生火时,现代社会就起头了. 之后的各类发觉,例如青铜,铁,蒸汽,电能等等,使社会进一步成长并塑制了汗青.那些成绩如斯主要以致我们常把人类汗青划分为几个期间并用各个期间的最新科技为其定名如:石器时代,青铜时代,铁器时代,等等。
