        【甲】于是入朝见威王，曰：“臣诚知不如徐公美。臣之妻私臣，臣之妾畏臣，臣之客欲有求于臣，皆以美于徐公。今齐地方千里，百二十城，宫妇左右莫不私王，朝廷之臣莫不畏王，四境之内莫不有求于王：由此观之，王之蔽甚矣。”
        王曰：“善。”乃下令：“群臣吏民能面刺寡人之过者，受上赏；上书谏寡人者，受中赏；能谤讥于市朝，闻寡人之耳者，受下赏。”令初下，群臣进谏，门庭若市；数月之后，时时而间进；期年之后，虽欲言，无可进者。

    Charles was always hardworking in school. He had decided that his first object was to get his lessons well, and then he could play with a good conscience. He loved playing as well as anybody, and was one of the best players on the ground. I hardly ever saw anybody catch a ball better than he could. When playing any game, everyone was glad to get Charles on his side.
    Charles would sometimes stay in at break. This, however, was very seldom; it was only when the lessons were very hard indeed. Generally, he was among the first on the playground, and he was also among the first to go into school when called. The teacher could not help liking him, for he always had his lessons well committed, and never gave him any trouble.
    When he went to college, the teacher gave him a good recommendation. He was so thoroughly prepared for college that he found it very easy to keep up with his class, and had much time for reading interesting books.
    At last he graduated and received his degree. His father and mother, brothers and sisters, came to his graduation ceremony. They all felt excited and loved Charles more than ever. Many situations of profit were opened to him; for Charles was now an intelligent man, and universally respected.
