The class was over in ten minutes, and the students came to the playground happily to play games. Look! Some students play football, some jump rubber bands, some throw sandbags, some throw handkerchiefs ... Suddenly, the quiet playground becomes very lively. The most interesting thing is throwing sandbags. A dozen classmates and I came to play with sandbags in the shade of a big tree. We are divided into four groups, with four students standing in the middle and four students standing on both sides. The rules of the game are: students on both sides throw sandbags at students in the middle. The students in the middle each have three lives. If the person in the middle keeps throwing sandbags, you can add one life, and if you are hit by people on both sides, you will lose one life. The students in the second group began to serve the ball. Li Ruoyu was immediately hit by a flying ball, and his life was lost at once. What a pity! It's really annoying to lose at the beginning! Shi Dui shouted: "We should be careful, we can only win this time, not lose!" " "Her voice really worked. The second encounter changed immediately. Zhu and I both caught each other's ball. We beat each other easily. Everyone jumped and jumped, so happy! Then we exchanged roles with each other and the "battle" began again. When we attacked, Xu Longfei of the other side was too slow, and I was a little worried about her. I moved like lightning, and the ball flew to the other side's position. My heart is pounding like a rabbit for fear of being caught by the other team. My "ball" actually hit two players of the other team. In this way, the "ball" flew around the field, and the students jumped up and down and cheered. Then the bell rang, and we had to retreat in a hurry. What a nostalgic ten-minute recess!
