题目：The pie chart below shows the main reasons why agricultural land becomes less productive. The table shows how these causes affected three regions of the world during the 1990s.
此题要求分析双图：饼状图和表格图。重点在于分析饼状图的静态比例分布和表格图的静态比例分配，饼状图的分析顺序按从大到小进行，表格图的最大值最小值是描述的重点（11.3，9.8，0）
The information given by the pie chart and the table is about the main reasons for worldwide land degradation and how three areas of the world were affected by the reasons over the 1990s.
（首段概括全表格内容，点明描述对象：全世界范围内土地产量下降的原因及1990年三个区域受影响的程度）
As we can see from the pie chart, there are four main causes of farmland becoming degraded in the world. Precisely, over-grazing had the largest proportion which occupies 35%. It is closely followed by deforestation and over-cultivation, taking up 30% and 28% respectively. In addition, there are also some other reasons, constituting only 7%.
（提出共有四种原因导致土地产量下降，按照比例由大到小的顺序分析四种原因）
The given causes affected different regions differently in the 1990s. Specifically, in Europe which had the largest proportion of land degradation (23%), 9.8% land degraded was due to deforestation. However, it only took up 0.2% in North America and 1.7% in Oceania. As for Oceania with 13% of total land degradation, the most serious cause was over-grazing (11.3%). Interestingly, there was no link between its land degradation and over-cultivation which made 3.3% land degraded in North America whose total land degraded accounted for 5%.
（分析影响欧洲土地产量最重要的原因-植被减少，并比较植被减少对美洲和大洋洲的影响；然后分析影响大洋洲土地产量的最重要原因-过度放牧，提出过度耕种并未对土地产生影响；最后分析影响美洲土地产量的因素）
All in all, it is clear to see that over-grazing and deforestation are the most important reasons for land degradation, and the reasons mentioned above played different roles in different regions during the 1990s.
（概括饼图：强调过度放牧和植被减少是影响土地产量的最主要原因；概括表格：指出地区差异）

语言表达
饼图和表格图有很多百分比需要逐一提出，本范文运用不同的表达方式描述这些百分比。用词和句式变化多端。
1 The information given by the pie chart and the table is about the main reasons for worldwide land degradation and how three areas of the world were affected by the reasons over the 1990s.
雅思小作文首段统一对原题进行paraphrase。本句用的句型是：The information given by…is about…可以通用到所有小作文中。并运用了两种常见的paraphrase的方法：（1）词汇和短语的替换，agricultural land becomes less productive替换worldwide land degradation，causes替换reasons；（2）将主动句改成被动句。
2 Precisely, over-grazing had the largest proportion which occupies 35%. It is closely followed by deforestation and over-cultivation, taking up 30% and 28% respectively. In addition, there are also some other reasons, constituting only 7%.
注意这三句中运用到的表示“占百分比”的表达：occupy, take up, constitute。此外，注意罗列几个百分比数时用到的方法：follow by, respectively, in addition。
3 However, it only took up 0.2% in North America and 1.7% in Oceania.
本句提到植被减少对北美及大洋洲农业产量影响时，尽量简化句子，不多对百分比的含义多加解释，因为前一句是关于植被减少对欧洲农业产量的影响。
逻辑结构
本文是典型的总分总结构的小作文。开篇先paraphrase原题，第二部分分两段，分别描述两个图表的细节。最后一句话对两个表格分别进行了高度的文字概括。
