一天中午,我躺在床上思考着怎样完成物理老师布置的作业——自制一把卷尺.我想,自己身为物理科代表,绝不能像打发任务似的去完成.不仅要把卷尺做得有特色,实用性强,还要有创造性! “叮”,我脑袋里的机器像是受到了刺激,突然开动起来.能否把传统的钢卷尺改为牛皮纸材料?能否 At noon one day, I was lying in bed and thinking about how to complete the assignment of a physics teacher - to make a tape measure. I thought, as a representative of the physics department, I would not be able to accomplish it like a mission. Not only did I need to have a tape measure Features, practicality, but also creative! “叮”, the machine in my head is like being stimulated and suddenly started. Can we change the traditional steel tape to kraft paper?
