Introduce a 50-word brush.

Hi! Boy, you must be curious, right? How can I like a pen? The pen I said is not a real pen, but a teacher. You may think, how can a teacher become a pen? Let me tell you slowly.

"Ding Lingling ..." At the beginning of class, my favorite pen became a pen. Because this is physical education class, we will practice long-distance running. This pen pours powerful and confident ink on us, and we immediately become very strong and summon up courage to rush to the finish line.

In science class, my favorite pen became a ballpoint pen again. Ballpoint pen contains the breath of nature. We are like a blank sheet of paper. Ballpoint pen draws a picture on white paper, depicting mountains and rivers, the moon, the milky way, ants and snails, and deeply imprints the fun in our hearts.

In Chinese class, my favorite pen became a writing brush again. Flowers float from this brush, and we become a paper wall, on which this golden brush can write beautiful chapters. The screen prints of pig snoring and Charlotte are printed in our minds and will never be erased.

In art class, my favorite pen became a crayon again. The colors of crayons are really rich: red, orange, yellow, green, cyan, blue and purple ... The blue sky, the vast land and the Yarlung Zangbo River Grand Canyon are all painted ... The colors are really beautiful.

This ever-changing pen allows me to swim in the ocean of knowledge. I like this pen very much.
