雅思写作：如何写出高分图表作文
“目的明确”，“主题鲜明”，“结构配置得当”是优秀图表作文的三大基本要素。数据和词汇的堆砌，甚至单词的改写永远无法打动阅卷考官，给你一个高分。
小作文： 图表作文
1. Summarize 写作目的、最重要的信息
2. Make comparisons 归类、
控制好下面的内容：
1、 开篇：明确指出文章的写作目的
a) 随着时间，变化
b) 大小的比较
2、 结尾：结合写作目的，明确的'给出图表中最为重要的信息
a) 看变化：哪些对象上升，哪些对象下降，哪些不变
b) 看比较：哪个对象是“最好王者”
3、 细节分类讨论，给出一些支持结论的证据或过程
分段模式：2+X (2代表开篇和结尾;X代表分类的结果和图形的数量)
开篇：
1) 重点要突出“写作目的”change or compare “C&C”
2) 名词照抄，动词和抽象名词替换，时间和地点不变，但要突出“指代”
下面是一篇以描述比较为主的文章范例：选材
e.g. Cambridge 8 – Test 1
The chart compares the proportions of overgrazing, over-cultivation, deforestation and others. The table compares the percentages of overgrazing, over-cultivation and deforestation in North America, Europe and Oceania during 1990 – 2000. 文章的开篇与提示句不同之处在于：你是在看过图表后产生的具体的描述。
结尾：
Overall, it is clear that overgrazing, over-cultivation and deforestation are main causes of global land degradation, and that the primary causes of land degradation in the three areas were different : North America (Over-cultivation)， Europe (Deforestation)， and Oceania (Overgrazing)， and Europe had the most seriously affected land of the three countries.
中间段： 分段，每段的主题句如何支持最后的结论 X= 2
第一段：第一句：最大值， while第二句：接近的值归类。 However, 其余的不重要的值
The most primary cause of land degradation in the world is over-grazing, accounting for 35%, while other two main causes are over-cultivation and deforestation, occupying 28% and 30% respectively. The reminder only takes up 7%.
23% of land in Europe was degraded, which was the most serious, and 9.8% of land degradation was caused by deforestation, as well as 7.7% (over-cultivation) and 5.5% (overgrazing)。 13% of land in Oceania was spoiled, and 11.3% of land spoiled was because of over-grazing, while 5% of land was degraded in North America, and 3.3% of the land degradation was subject to over-cultivation.
A complete composition

下文是一篇以描述趋势变化为主的范文：素材来自Cambridge 8 Test 2
开篇和结尾 – 重点强调写作的目的是：变化;结论重点回应这些对象是如何变化的。将占比例最大的对象名称，作为次要内容，写在开头段是为了保持文章的前后一致。
