混合类数据类图表作文写作

Mixed graphs writing – Land Degradation

混合类图表写作要点与步骤 ：
混合类图表增加了写作的复杂程度，饼图显示了全球土地退化的原因，而表格图按全球三个区域显示了土地退化的原因。你必须先做1到2句话的概述，把最明显和重要的信息凸显出来。写作字数在150-200个单词。首先清晰地布置文章的结构，比如（i）简介（ii）总述（iii）饼图段落（iv）表格段落（v）一句话概括两个图表的结论（如果字数已经超过了200字 ，最后的概括可以不写）。
本文写作还会遇到一些几个词的同义词：
“region”–>“area”,
“causes”–>“factors”,
“percentage”–> “proportion”
Land Degradation STEP-BY-STEP SAMPLE ANSWER

写作第一步-介绍
按照以外惯例，把题干部分的英文改写一下，使用同义词和句子结构的变化复述一下就变成你的开头介绍了。例如“…为什么农业耕地的产量会下降”可以改成“为什么农业耕地的产量会随着时间的推移而下降”。注意时态的变化。饼图是一般现在时，而表格是一般过去时（1990年代的数据）。
SAMPLE INTRODUCTION “The pie chart outlines the key factors as to why land used for agriculture produces less over time, while the table gives a breakdown of the effect these causes had on agricultural land in three regions during the 1990s.”

第二步–总述
查看图表时注意分析明显的“大”数据。饼图显示三个原因对农业耕地的影响几乎相同（过度放牧—35%，毁林–30%，过度种植–28%）。然而，表格图显示了这三种原因在三个地区的影响幅度是大不相同的。饼图和表格图可以帮助我们编写总述（概述）。
“Overall, over-grazing, deforestation, and over-cultivation are all significant causes of land degradation globally, but the causes of less productive land in specific regions varies.”

第三步 饼图正文
按照饼图四个部分数据来组织本段文字。
“The pie chart shows that over-grazing by livestock is the most significant factor in land becoming degraded with 35% of land being affected in this way. However, this is closely followed by deforestation (30%) and over-cultivation (28%), with the remaining 7% being made up of other causes.”

第四步 表格图正文
按照表格图四个部分数据来组织本段文字。
“With respect to the table, it is clear that in the 1990s the North American region had the lowest amount of degraded land at just 5%. Of this land, about two-thirds was damaged by over-cultivation, just under a third by over-grazing, and a minimal amount by deforestation. In contrast, at the same time almost a quarter (23%) of arable land in Europe was degraded. Unlike the American region, the main factor in Europe was deforestation, with 9.8% of total land affected. Moreover, over-cultivation (7.7%) and over-grazing (5.5%) were also majorly responsible for the deterioration of land quality. In the final region, Oceania, the main cause of land degradation was clearly over-grazing with 11.3% of land being affected by this out of a total of 13% of land degraded in total. Conversely, over-cultivation appeared to play no role in this part of the world, while deforestation affected only a relatively small amount (1.7%)”

结尾句：
现在答案文字已经超过200字了，主要信息都已经涵盖了，所以没有必要再写结论，这个结尾句与前面的总述（概述）非常相似。
