    I was happy in those days before I started going to school. Because I had good neighbors to play with. I played with them from morning to evening. We played games outdoors, dressed up as cowboys and rode around on our tricycles(三轮车) happily.

    At the age of five, I had to go to kindergarten(幼儿园) and it was quite hard for me at first. I felt very sad about having to leave my mother each morning. I cried and wanted my mother around. As the days went by, however, I made friends easily in my class. I became happy again and looked forward to leaving my house each morning.

    I still remember those days when I was learning to ride a bicycle. I fell several times but I never gave up. Finally, I was able to join my friends riding around on my bike.

    Another memory I like is the end-of-year concert held at the kindergarten. I was chosen to play the role of Jack in the play, Jack and the Magic Beans. I became the superstar that night and received praise for my performance.

    What a wonderful childhood I had! At times I really wish I could go back to those days.
