差在这三点，一看就懂：
1. 结构套路：范文永远是“描述图表-分析原因-总结趋势/影响”三段式，自己写容易扯远，比如大谈个人感受。
2. 用词和句式：范文用“As is revealed in the chart...”开头，自己写可能直接“The chart shows...”；范文用“This phenomenon can be attributed to...”分析原因，自己写可能只会“Because...”。
3. 扣题深度：范文结尾会联系社会发展（如“reflects broader trends in...”），自己写可能就简单重复数据。
拿2013年真题（大学生*情况）举例：
自己写可能：“Many college students do part-time jobs. They want to earn money. It’s good for them.”
范文范本：“The bar chart clearly illustrates the proportion of students taking part-time jobs across four university years. This trend is primarily driven by the growing need to gain practical experience and alleviate financial burdens. Such a phenomenon highlights students’ increasing awareness of preparing for future careers.”
直接套的句式（背完就用）：
开头：“As is depicted in the chart, [数据/现象].”
原因：“Two major factors contribute to this: firstly, ...; secondly, ...”
结尾：“In summary, this trend mirrors a broader shift in [社会/教育领域].”
评分标准核心：
内容对不对（别跑题）
结构清不清（三段式最稳）
词句有没有亮点（换几个高级词，比如用“significant”代替“big”）
错误多不多（语法、拼写尽量少错）
完了。
