Teenagers are in the initial stage of forming a long body, long knowledge and long world outlook. They have a wide range of interests, strong imitation, great plasticity, immature ideology and politics, and are easy to accept external influences. In order to ensure the realization of people's all-round development policy and promote the healthy growth of teenagers, ideological and political work must educate them to abide by the law and enhance their legal consciousness, so as to improve their consciousness of obeying the law and resist the influence of unhealthy consciousness and behavior on teenagers. We should gradually educate students to establish a correct outlook on life, help them have a basically correct understanding and attitude towards the purpose and significance of life, guide them to love the motherland, the party, the socialist system and the people, and encourage them to study hard for the bright future of the motherland and the great cause of the four modernizations. To build our country into a powerful modern socialist country, we need batches of qualified construction talents. Today's study is to learn skills and talents for tomorrow's socialist modernization, to link personal study with the future of the motherland, and to establish the purpose of learning for socialist modernization.
