世界历史博览3(A Broad View of the Word History 3)

当人类生活在洞穴，隐藏于悬崖的时候；当人类唯一的工具是石头的时候；当每个人不得不为自己的食物而进行打猎的时候；当人类的衣服是以动物的皮做成的时候。那时没有城市，没有大型的建筑，没有现代生活中的安逸，从史前史到现代世界的跨时空旅程，世界历史的发展是曲折而神奇的，为了使青少年朋友更好地了解世界历史，我们编著了这套《世界历史博览》。(There was a time when people lived in caves and hidden in the cliff; when the only tool for them was the stones; when everyone had to hunt for his own food; when human being used an animal furs and skins for clothes. There was no cities, no large buildings, no peace or comforts of modern life; a journey across time and space from the prehistory to the modern world, the development of the world history is tortuous and mysterious. In order to help the young people to better understand the world history, we compiled this A Broad View of the Word History.)
