考研英语二大作文主要是图表类作文，即根据所给图表中的信息进行写作，根据往年真题可以知道经常出现的图表包括饼图，柱状图，表格和折线图等。针对图表类作文题目，考生复习时应从两方面着手：文章构成和常用表达。

文章构成。图表类作文通常可分为三段：首段主要对图表进行描述，该段的关键在于抓住主要信息点，即主要数据，例如最值和变化的整体趋势等。第二段则主要是分析图表中数据出现的原因、反映的问题或解决办法等。作为主体段，分析原因、问题或措施时可以分点来写，列出三点左右即可。尾段通常是总结上文，或根据图表中的数据进行预测，一到两句话即可，点到为止，不要写太长。

常用表达。知道每个段落需要写作的内容后，剩下的问题就是用英语地道地表述出来。针对图表作文，有很多可以套用的句式和表达，考生在复习时应该多积累这样的表达，并结合大量的练习，达到能够灵活运用的水平。下面是三大段落中常用的一些句式，考生可参考使用。
