This afternoon, all the third and fourth grade students in our school went to the playground to learn to do exercises. The teacher asked us to review the first to sixth exercises we have learned. We were very skilled, so we began to learn the seventh to ninth exercises.

First, the teacher asked two sisters in grade six to show us. The elder sister's movements are light and graceful, accompanied by the beat shouted by the teacher, like two dancing butterflies, which fascinates us. It is our turn to do it. Let's start with decomposition kinematics according to elder sister's demonstration. Although we all want to learn at once, it is easier said than done. Instead of learning, we stumbled and made a fool of ourselves. Some students can't help blushing, and some students can't help laughing. The teacher looked at us in a hurry and couldn't help laughing. The teacher asked my elder sister to teach us again. This time, we looked more carefully and finally learned. We jumped for joy.

Unconsciously, a class passed, so we took a break and began to practice again. The teacher asked us to do it in class. All the students in our class are ready to try. They all want to win the first prize for us. Unexpectedly, the class was over before it was our turn to perform. We feel a little disappointed and a little sorry. But it doesn't matter, there will be another chance.

Today's study is over. Although we are all sweaty, thirsty and tired, we are happy because we have overcome another difficulty and learned a skill.
