One day, on my way home, an apple flew towards 1 . It just landed(掉落) in front of my feet. How lucky I was! I guessed a troublemaker(捣蛋鬼) on the other side threw 2 apple over the wall. Thinking it was a small accident, I didn't care 3 it.
A week later, when I 4 the same place, an apple came flying again. This time it landed on the roof(屋顶) next to the wall. I was a bit angry, 5 again, I did nothing.
Yesterday, while I was walking back home, I saw another apple. It was flying so fast! Seeing that, I was 6 than I was last time. If he kept doing this 7 action might hurt others. So I decided to teach him a lesson.

Finally I planned to call the school to find out who was the troublemaker. And I wanted all the 10 to learn from his mistakes.
