The requirements for high school graduation have just changed in my community. As a result, all students must 36 sixty hours of service learning, 37 they will not receive a diploma. Service learning is academic learning that also helps the community. 38 of service learning include cleaning up a polluted river, working in a soup kitchen, or tutoring a student. 39 a service experience, students must keep a journal（日志）and then write a 40 about what they have learned. Supporters claim that there are many 41 of service learning. Perhaps most importantly, students are forced to think 42 their own interests and become 43 of the needs of others. Students are also able to learn real-life skills that 44 responsibility, problem-solving, and working as part of a team. 45 , students can explore possible careers 46 service learning. For example, if a student wonders what teaching is like, he or she can choose to work in an elementary school classroom a few afternoons each month. 47 there are many benefits, opponents （反对者） 48 problems with the new requirement. First, they 49 that the main reason students go to school is to learn core subjects and skills. Because service learning is time-consuming, students spend 50 time studying the core subjects. Second, they believe that forcing students to work without 51 goes against the law. By requiring service, the school takes away an individual's freedom to choose. In my view, service learning is a great way to 52 to the community, learn new skills, and explore different careers. 53 , I don' t believe you should force people to help others – the 54 to help must come from the heart. I think the best 55 is one that gives students choices: a student should be able to choose sixty hours of independent study or sixty hours of service. Choice encourages both freedom and responsibility, and as young adults, we must learn to handle both wisely.
