As is known to all that we students have to fix our attention on our lessons, so we know few of society. A holiday is the best time and the better chance to make up for that. Take a part-time job is a good form of social practice. Neither we have learned in books nor in class can have the same important effect on us as what we had learned through personal practice. In social practice, we can surely make a rapid progress in both knowledge and practical ability. However, when we take part-time jobs, we may get paid more or less help our families. Thus, I suggest we senior school students can take part-time jobs in their holidays, if possible.
