One possible version:
According to a recent survey. About 25 percent of colleges 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.From joozone.com.
Why do they want part – time jobs? First, they want to earn money to help cover the increasingly higher college tuition. Second, they hope to be economically independent and buy whatever they want.
In my opinion, by doing part – time jobs, college students can gain some society experience and broaden their outlook. What’s more, part – time jobs can provide them with a valuable opportunity to know the outside world. So it’s of great significance for college students to do part – time jobs.
