Yesterday afternoon, Teacher Zhang assigned a math problem. I can't figure it out after racking my brains at night. Just as I was scratching my head, my father came over and gave me a helping hand. With a little help from him, I was suddenly enlightened. It's really (the mountains are heavy and the waters are heavy, and there is no road to doubt, and there is another village). So I solved the problem quickly. Later, I got a hundred points in the exam, and I was a little proud. Dad said earnestly (modesty makes people progress) and (pride makes people fall behind)
