     How words came into being is unknown.All we assume(推测)is that some early men invented certain

sounds,in one way or another,to express thoughts and feelings,actions and things,so that they

could talk with each other.Later they agreed upon certain signs,called letters,which could be put

together to show those sounds,and which could be written down.Those sounds,whether spoken or

written in letters,are called words.

    The power of words,then,lies in their associations-the things they bring up to our minds.Words

become filled with meaning for us by experience;and the longer we live,the more certain words bring

back to us the happy and sad events of our past;and the more we read and learn,the more the

number of words that mean something to us increases.

    Great writers are those who not only have great thoughts but also express these thoughts in words

which have powerful effects on our minds and feelings.This clever use of words is what we call literary

style(文体). Above all,the real poet is a master of words.He can express his meaning in words which

sing like music,and which by their position and association can move men to tears.We should therefore

learn to choose our words carefully and use them correctly,or they will make our speech silly and

common.

瑞安是历史文化名城,置县迄今有1760多年,自古以来文风鼎盛,人才辈出,有着“理学名邦”,“东南小邹鲁”之美称。在历史上曾形成瑞安三个文化巅峰时期:东瓯文化、永嘉学派、晚清新学。出现过陈傅良、高则诚、孙诒让等历史文化名人。保存着较多的历史文物,其中玉海楼、利济医学堂等更是重要的历史“教科书”。蓦然回首,老街旧屋却日益难觅。保护历史文物,留存瑞安记忆,成为政府、专家学者及瑞安市民的共识,有关部门制定了《瑞安历史文化街区和历史建筑保护暂行办法》。瑞安的老街古屋和历史文物沉淀了浓厚的传统文化,展现了瑞安历史文化真实而独特的魅力,具有重要的历史和人文价值。保护瑞安历史文物和老街古屋,对于继承和发扬民族优秀文化传统,促进瑞安社会主义精神文化建设、物质文明建设和政治文明建设,都具有重要而深远的意义。
