笔者近来阅读了山西、江西、天津等省市正在使用的试验教材（以下简称试验教材），并与多数省、市仍在使用的原版教材（以下简称原版教材）做了比较，从中发现了这两种版本的教材的实验内容之间的一些相同之处和不同之处。我认为试验教材基本内容是在原版教材的多年实践的基础? The author has recently read experimental textbooks (hereinafter referred to as experimental textbooks) that are currently being used in provinces and cities such as Shanxi, Jiangxi and Tianjin, and compared them with the original textbooks (hereinafter referred to as the original textbooks) that are still in use in most provinces and cities. There are some similarities and differences between the experimental content of the two versions of the textbook. I think the basic content of the experimental teaching material is based on the practice of the original textbook for many years.
