教学过程创设情境并执行(8分钟) 学生在上节课充分查阅资料,对中国和世界的铁路发展已经有了一定程度的认识,鉴于此,先把学生分成14个小组,每组代表一个城市:如北京、成都、徐州、郑州、兰州、株洲等,请学生根据自己的自学和课余的讨论,在老师预留的中国铁路空白图上绘制出经过自己代表城市的主要铁路干线,小组内可以互相补充,最后请每组派代表发言,给大家介绍自己组内的研究情况。其他组同学也可以补充。

They had a certain degree of understanding of the railway development in China and the world. In view of this, students were first divided into 14 groups, each representing a city. : If Beijing, Chengdu, Xuzhou, Zhengzhou, Lanzhou, Zhuzhou, etc., ask students to draw their own main railway lines on the blank map of the Chinese railway reserved by their teachers according to their self-study and after-school discussions.
