一.思路 

第一步：看懂并理解图表的含义，这是写好图表作文的前提。总结规律、趋势，归纳特点或增减性。

第二步：应该仔细研究图表所给出的大量信息，选择出最能说明图表主题的典型数据和信息，然后根据全文的主旨去组织运用所获取的关键信息。切忌对图表数据一一描述。

第三步：根据自己的分析结果和文章题目写出各段的主题句。

二.文章结构  

一般以三段式写作方法来组织文章。每段内容根据题目提纲来写，一般如下：

第一段总结归纳信息反映的整体情况，点出主题思想。

第二段回答第一段所得出的问题，对数字、数据等做出有条理的分析比较，找出产生变化的原因。

第三段做出总结或给以简单的评论。

三.必备词汇和句型
