Nowadays many universities encourage and organize students to take part in social practice activities. During the holidays, more and more students choose to be the volunteers, take part-time jobs, or take part in other practical activities alike. It’s obvious that social practice is playing a more and more important role in China’s college education。
Undoubtedly, college students have benefited a lot from social practice. Above all, they are provided with more opportunities to contact the real world outside the campus. Moreover, in social practice activities, students can apply their knowledge to the solution to the practical problems. So their practical skills are improved greatly. Besides, social practice helps strengthen students’ sense of social responsibility。
Considering the above-mentioned, I think, it is necessary for college students to participate in social practice. However, social practice may bring some problems. For example, some students spend too much time in taking part-time jobs so as to ignore their study. Therefore, we should try to balance the relationship between social practice and study。

毫无疑问,大学生社会实践受益匪浅。最重要的是,他们提供了更多的机会接触校园以外的现实世界。此外,在社会实践活动中,学生可以应用他们所学的知识去解决实际问题。所以他们的实践技能得到了较大的改善。此外,社会实践有助于加强学生的社会责任感。
考虑到上述,我认为,有必要对大学生参与社会实践。然而,社会实践可能带来一些问题。例如,一些学生花太多时间在兼职工作,忽视了他们的研究。因此,我们应该试着平衡社会实践和学习之间的关系。
