Chalk, when it lies quietly on the platform, no one will notice it, but whenever the teacher picks it up, it gives us students knowledge. What about itself? The sacrifice was not stopped until it was ground into powder. At this time, I remembered two poems: the silkworm in spring will weave until it dies, and the candle will dry the wick every night. Chalk, like silkworm and wax torch, has the spirit of serving the people all his life.
Chalk, with its short life, spreads civilization and knowledge.
I praise chalk, but also praise the teachers who have worked hard with chalk and scattered their efforts on our seedlings!
