“刷——刷——”粉笔在黑板上移动,渐渐地,越变越短,越变越短,成了粉笔头,但它却为同学们创造了一个无比广阔的知识天地。那一行行字就是它描绘出的知识的天地和海洋,它就像是一位导游,带领我们在知识的天地里徜徉,又好似一位教练,带领我们一同在知识的海洋里遨游。
“Brush - brush - ” chalk moving on the blackboard, gradually, getting shorter and shorter, shorter and shorter, became chalk, but it has created a vast knowledge of the world for the students. The line is the world of knowledge and the sea it depicts. It acts like a guide and leads us in the world of knowledge. It is like a coach who leads us together in the ocean of knowledge.
