One year ago, I was in great trouble. I work hard at English and devoted all my spare time to practise it. But I failed to pass the mid-term exam, which made me great disappointed. So I asked my grandpa for advice when I got to home. Hearing that I told him, he said, “To some extent, exam results sometime can’t truly reflect your ability. You can’t judge your progress by one examination.” He encouraged myself to work hard for long time to check my results. I took my grandpa’s advice. Now my English is much better than ago. From my experience, I feel that we should listen to opinion from old people.
