As is known to all that our students of today have to fix our attention on our lessons, so we know few of society. A holiday is the best time and the best chance to make up for that. Take a part-time job is a good form of social practice. That we have learned in books and in class can’t have same important effect on us as what we have learned through personal practice. In social practice, we can surely make a progress in both knowledge or practical ability. Beside, when we take a part-time job, we may got paid more or less to help our family. Thus, I will say a senior school student should take a part-time job in their holidays, if possible.
