Walter’s goal in life was become a successfully doctor. He knew he had to finish high school first, so he put his heart into her studies----in particular, biology, chemistry and maths. Because he worked hard at these subjects, Walter became good at it. However, Walter forgot that he needed to master some other subjects beside those he had been chosen. As a result, Walter fails in both English and Chinese in the end of the second school year. But he had to repeat these subjects and he was almost unable to graduate like planned. Walter learned a good lesson. ___________________________________________________________________________-
