    解析:
    The bar chart shows the general trend of university students whotake parttime jobs at different stages during their college life.Seeing from the chart,more than half of the college students,about 66.77%take a parttime job at their first year.And the proportion increases slightly year by year,til the last year,the proportion reaches the maximal number,surging to 88.24%.There are basically three reasons behind this trend.To begin with,most students are eager to take a parttime job in the purpose of earning some money,which can ease their parents'burden.Besides,they can acquire more experience before officially entering the society.And with more experience,they can easily get a job compared to those who do not have any experience.Finally,they can not only turn what they have learnt into the application,but also learn more which they cannot obtain from their books.In my view,getting a parttime job is a good practice.However,the major task of students is still the study.They should make a balance between their academic life and their working life.
