She made learning fun and showed me how beautiful this language is. To achieve my goal, I know I need to work hard. First, I will study English every day to improve my skills.

With it, I can look up new words in a second, watch educational videos, and even have online lessons with my teachers. It makes studying much more convenient. However, every coin has two sides.

I will never forget the day when I took part in a charity run last autumn. It was held to raise money for children in poor areas. Although I am not good at running, I decided to try my best. During the run, I felt very tired and wanted to give up. But when I saw other runners, including some elderly people, keeping going, I felt encouraged. Finally, I made it to the finish line. This experience taught me that perseverance is the key to success. Now, whenever I face difficulties, I remember that day and tell myself not to give up easily. 学科网（北京）股份有限公司 $
