  In the earliest stages of man’s development he had no more need of money than animals have. He was content with very simple forms of shelter, made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him. As he became more civilized, however, he began to want better shelter, more efficient tools and weapons, and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands. For these things he had to turn to the skilled people such as smiths, leather workers or carpenters. It was then that the question of payment arose.

At first he got what he wanted by a simple process of exchange. The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer in exchange for an axe or a plough (犁). But as more and more goods which had no fixed exchange value came on the market, exchange became too complicated to be satisfactory. Another problem arose when those who made things wanted to get stocks of wood or leather, or iron, but had nothing to offer in exchange until their finished goods were ready.

Thus the difficulties of exchange led by degree to the invention of money. In some countries easily handled things like seeds or shells were given a certain value and farmer, instead of paying the smith for a new axe by giving him some meat or grain, gave him so many shells. If the smith had any shells left when he had bought his food, he could get stocks of the raw materials of his trade. In some countries quite large things such as cows or camels or even big flat stones were used for trade. Later, pieces of metal, bearing values according to the rarity (稀有) of the metal and the size of the pieces, or coins were used. Money as we know it had arrived.

某桥梁工地的简支板梁架设，由专业架梁分包队伍架设。该分包队伍用2台50t履带式起重机，以双机抬的吊装方式架设板梁。在架设某跨板梁时，突然一台履带式起重机倾斜，板梁砸向另一台履带式起重机驾驶室，将一名起重机驾驶员当场砸死，另有一人受重伤。事故发生后，项目经理立即组织人员抢救伤员，排除险情，防止事故扩大，做好标识，保护了现场，并在事故发生后第一时间内报告企业安全主管部门，内容有：事故发生的时间、地点、伤亡人数和事故发生原因的初步分析。在报告上级以后，项目经理指定技术、安全部门的人员组成调查组，对事故开展调查，企业安全部门和企业负责安全生产的副总经理也赶到现场参加调查，调查中发现下述现象：
(1)项目部审查了分包方的安全施工资格和安全生产保证体系，并作出了合格评价。在分包合同中明确了分包方安全生产责任和义务，提出了安全要求，但查不到监督、检查记录。
(2)项目部编制了板梁架设的专项安全施工方案，方案中明确规定履带式起重机下要满铺路基箱板，路基箱板的长边要与履带式起重机行进方向垂直，但两台履带式起重机下铺设的路基箱板，其长边都几乎与履带式起重机行进方向平行，而这正是造成此次事故的主要原因之一。
(3)查到了项目部向分包队伍的安全技术交底记录签字齐全，但查不到分包队伍负责人向全体作业人员的交底记录。
(4)仔细查看安全技术交底记录，没有发现路基箱板铺设方向不正确给作业人员带来的潜在威胁和避难措施的详细内容。
(5)事故造成的直接经济损失达50万元。通过调查，查清了事故原因和事故责任者，对事故责任者和员工进行了教育，事故责任者受到了处理。
