图表类作文的写作，一共分三段
第一段：描述图表内容，阐明图表趋势，罗列具体数据
第二段：阐述原因或者影响
第三段：表达建议或预测
以2010年这篇作文为例
Presented above is a bar chart that illustrates significant distinctions regarding the percentages of college students who take part-time jobs from freshman years to senior years. 第一句描述图表的内容，这里是得分点，很多同学容易漏掉这一句，监考老师看到第一句没写，就直接开始扣分了。In the light of the data provided, we are aware that the percentage of students who have part time jobs is fairly high, rising slightly 图表趋势 from freshmen students at 66.77% to junior students at 71.93% and increasing significantly to 88.24%罗列具体数据 among senior students. 图表趋势和具体数据都是得分点
The stimulating factors 开始写原因，图表类作文第二段，原因或者预测二选一即可，都写字数就太多了responsible for the distinctions can be summarized as follows. To begin with, the differences are bound up with the fact that the more the students learn at university, the more they want to apply what they learn to practice in real work situations. Moreover, another fact that cannot be ignored is that the students are becoming more financially independent, so they desire a part-time job to be more on their own feet. Last but not least, we may realize that the senior students put higher emphasis on a better preparation for the career after graduation.罗列3个原因，每个原因用不同的句式引出，表达不重复，为高分句型
Considering the arguments above, we can safely come to a conclusion that the distinctions of the percentages described is nothing but a blessing. And I firmly believe that it will continue in the forthcoming years. 最后一段，预测或者建议二选一，这里写的是预测。预测很好写，在未来的一段时间内，下降或者上升
