我在对5年级的学生讲授植物学头几节课的时候,便开始告诉他们一些农业知识,以便使他们养成一些有关农业方面的技能. 比方说,学生们在我的领导下,在秋季参观谷物脱粒场的时候,他们完成了实习种子构造的任务.在脱粒场他们观察了清粮机(??)、选种机(??)的作业情况,同时也观察了各种小麦品种的和其他作物的种子,对这些品种进行了比较,他们并且直接参加了工作.我利用这第一次参观的机会来和集体农庄建立联系,以便使日后进一步地扩大这种联系. 学生们在脱粒场上选择了各种品种的少量种子,并把它们装在预先备好的火柴盒中.我们在课堂上仍然继续研究种子.
When I taught the first few lessons of Botany to students in Year 5, I began to tell them some agricultural knowledge so that they could develop some skills in agriculture. For example, under the leadership of my students, When they visited the grain threshing ground, they completed the task of constructing seed intercourse, where they observed the operation of the grain harvesting machine and the seed selection machine, as well as the effects of various wheat varieties And other crops, compared these varieties, and they worked directly and I used this first visit to establish contact with the collective farms in order to further expand this connection in the future.Students are threshing The field selected a few seeds of all varieties and packed them in a pre-made matchbox, and we continued to study the seeds in the classroom.
