时间介词at,in,on的辨析

1、时间介词at, in, on的辨析常见的时间介词at,in,on等，是平时考试特别容易考到的点，也 是中考的必考点之一。笔者结合自己的教学经验，发现学生对时间介 词的基本用法掌握不佳。究其缘由，笔者认为有以下几点：1 时间介 词的用法较为繁琐，学生觉得麻烦，不用心去理解记忆。2部分教师 把吋间介词的用法讲得过于全面，但考试只侧重其常见用法。学牛消 化不到位，考试易出错。3学习方法不佳。学生死记语法概念，没有 理解到位，把基木用法混淆。笔者建议不要过分地记忆一些概念和术 语，而是要结合实例来理解其基本用法。为方便学生更好地掌握本部 分内容，笔者将at,on,in的基本用法总结并附上适当的练习题。
