Mistake

My English grade wasn't good, my parents were very angry. So they said a lot of things to me. For example, if you don't get good grades, you must study harder. If not, I will hit you untill your English grade improves. That day, I was in my room crying. After that month, I tried to study English hard. In the classroom activities I asked the teacher questions and sometimes I asked friends. But I know this is not enough, my English was still very bad, so I had to study twice as hard as other people. After the exam, my grades improved a lot, and my parents were happy. They told me "If you want to do something you must do it well." After that, I feel that a person's potential is not limited, as long as they try hard.
