笔者参加过几次高考和中考的改卷,在改卷过程中,发现总有不少学生在书写化学反应方程式时不写出反应条件或者写错反应条件,这反映出部分教师在教学时不够重视反应条件,这是很不应该的。高考评分标准中有一条,化学方程式反应条件不写或写错的,该方程式不给分,这样的规定是有道理 The author participated in several college entrance examinations and examination reforms. During the rewriting process, it was found that many students did not write reaction conditions or write wrong reaction conditions when writing chemical reaction equations. This reflected that some teachers were not enough in teaching. Focusing on the reaction conditions is very bad. One of the college entrance examination scoring standards, chemical equation reaction conditions are not written or wrong, the formula does not give points, such a provision is justified
