参考范文：
Education serves multiple purposes, and there are different perspectives on its objectives. Some argue that the purpose of education is to prepare individuals to be useful to society, while others contend that its purpose is to help individuals achieve personal ambitions. In my opinion, education should strike a balance between these two aspects.

On one hand, the goal of education is to equip individuals with the skills and knowledge necessary to contribute to society. By acquiring practical abilities through education, individuals can make meaningful contributions to the betterment of society. For instance, those who receive medical education can save lives and improve public health. Moreover, education plays a crucial role in cultivating citizens' sense of responsibility and social values, which are essential for creating a harmonious and thriving community.

On the other hand, education should also focus on empowering individuals to pursue their personal ambitions. Every person has unique talents, interests, and dreams, and education should provide opportunities and resources for individuals to develop and achieve their full potential. Personal achievements and aspirations not only bring fulfillment to individuals but also drive social progress. Many groundbreaking inventions, artistic creations, and societal changes have been realized by individuals who pursued their own ambitions through education.

In conclusion, I believe that the purpose of education should encompass both preparing individuals to be useful to society and helping them achieve personal ambitions. Education should aim to cultivate well-rounded individuals who can contribute to the betterment of society while pursuing their own goals. By striking this balance, education can fulfill its role in fostering both personal development and social progress.
