文章结构
Happiness in My Life
Happiness is important in our lives. In fact, I think happiness springs from love in our hearts.
I’ll never forget one thing. Once, I had a bad mark in a maths exam. I was nervous and afraid to meet my parents. But when I got back home late, my parents knew what happened, and they said to me, “It doesn’t matter. Remember we’ll be always beside you when you need help. We believe you can do better next time.” This touched me greatly and I decided to work harder and harder. At last, I made great progress.
I feel happy. Whenever I'm in trouble, I can feel my parents’ love. I want to be a good child for my parents.
