题目我国古代货币是历史上留存至今数量最多、内容最丰富的实物资料。币制的沿革和形制的变化直接反映了各个历史时期政治、经济的状况、铸造技术的进步及文字书法艺术的发展态势。你知道最早的钱是什么样子吗?在漫长的经济发展史中,钱发生了哪些变化?未来社会中,钱的变化趋势又是怎样的?请分组查找有关资料,了解货币起源和发展的情况、与之相关的历史事件和历史人物,以及钱的其他知识,在班上讲解,并以“钱:昨天——今天——明天”为题写一篇作文。(新人教版) 提示:本次说明文的写作训练,我们应该从以下几个方面做起: 一、运用准确的说明语言。由于平时同学们对货币的了解甚少,而说明文最基本的要求之一,就是语言要准确,所以,要写好这篇说明文,查找、收集资料尤为重要。查找资料的途径有图书室、网络等。二、采用恰当的说明顺序。“最好的说明顺序,就是最容易让人明白的顺序,最恰当的说明顺序,就是条理清楚,能顺畅便捷地达到说明目的的顺序。”从题目的要求看,我们要写出钱的昨天、今天、明天,那么最主要的说明顺序就是时间顺序了。当然, 为了把对象说明得更加清楚,也可以辅以其他的说明顺序。三、使用正确的说明方法。要把货币的起源和发展等方面的情况说明白,就必须综合运用多种说明方法。在使用说明方法时要注意:下定义要科学,列数字要准确无误,画图表要严整有序, 等等。(曾维惠) Topic The ancient Chinese currency is the most substantial and richest physical data ever retained in history. The evolution of the currency system and the changes in the shape system directly reflect the political and economic conditions in various historical periods, the progress of casting technology, and the development of the calligraphy art. Do you know what the earliest money looks like? In the long history of economic development, what has happened to money? What is the trend of money in the future society? Ask the group to find relevant information to understand the origin and development of the currency. The related historical events and historical figures, as well as other knowledge of money, were explained in the class and wrote an essay entitled “Money: Yesterday - Today - Tomorrow”. (Newcomer Version) Tip: In the writing training of this exposition, we should start from the following aspects: First, use an accurate description language. As the students usually know very little about the currency, one of the most basic requirements of the text is that the language should be accurate. Therefore, it is very important to write this explanatory text to find and collect information. The ways to find information include library, internet, and so on. Second, use the appropriate description order. “The best description order is the order that is most easily understood by people. The most appropriate order of explanation is clear and orderly, and it can smoothly and quickly reach the order of explanation.” From the requirements of the title, we have to write the money yesterday. Today, tomorrow, then the most important order of explanation is the chronological order. Of course, in order to explain the object more clearly, it can be supplemented with other explanation orders. Third, use the correct instructions. To explain the origins and development of money, etc., it is necessary to use a variety of explanatory methods. In the use of instructions and methods should pay attention to: the definition of science, column numbers to be accurate, drawing charts to be strict and orderly, and so on. (Zeng Weihui)
