The research on classification ability is more in kindergartens and more in primary schools. Research by cognitive psychologists has found that children under 0-1 years old basically have no classification ability, and they mainly rely on individual perception. The classification ability of children aged 1-3 has begun to sprout, but the concept of "category" has not yet formed. The classification of children aged 3-5 is basically still based on external perceptible dimensions such as shape and color. For example, children in small classes in kindergartens are asked to classify red plastic balls, red apples and bananas. They will divide the balls and apples together, either according to the shape (circle) or according to the color (red), but they will not put apple kernel bananas together according to the function (edible).

In this practice, I feel very deeply that in school, there are a lot of theoretical studies, and they are multi-faceted, almost all-encompassing. However, in actual work, one may encounter the situation that one has not learned from books, or that one may not use the knowledge from books at all.如今，敌人在明，他们在暗，偌大的山野。板栗心中高兴。1973年，某部队通信连里，班长韩琳、新兵姜士安、张雁南在一起学习、生活。出身贫苦的农村兵姜士安在生活上受到了韩琳细致入微的关心，这使他渐渐喜欢上了善良、漂亮的韩琳。从小就娇生惯养的张雁南也在韩琳的帮助下不断的提高着自己的能力。而韩琳在努力学习、刻苦工作的同时对英俊、潇洒的军宣队队员彭湛渐生好感。　　姜士安的父亲在农村老家里给姜士安找了一个比姜士安大四岁并且没有文化的未婚妻。这使姜士安陷入矛盾之中……军事会议就这样做出了安排，韩信看着将领们离开大帐，心中也是有限忐忑。
