One possible version:
According to a recent survey, about 25 percent of college students have a part-time job. During summer vacation, this figure will increase to 72 percent. College students are working as tutors, waiters or salesmen etc.
Why do college students want part-time jobs? The main reason is that they hope to be economically independent. If so, they can buy whatever they need in daily life. And meanwhile, they may help cover their increasing college tuition.
I think it is good for college students to do part-time jobs. By doing part-time jobs, they can gain some society experience and broaden their outlook. What is more, part-time jobs can provide them with a valuable opportunity to know the outside world.
