剑桥雅思真题系类对于任何一个备考雅思考试的考生而言都是相当有价值的资料，考生要吃透里面的知识点会收获很大。下面，前程百利小编为大家带来的是雅思小作文之土地退化情况分析，一起来看一下吧。
雅思作文题目：
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.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant. (剑8 test1 task1)
范文：
The pie chart shows that there are four main causes of farmland becoming degraded in the world today. Globally, 65% of degradation is caused by too much animal grazing and tree clearance, constituting 35% and 30% respectively. A further 28% of global degradation is due to over cultivation of crops . Other causes account for only 7% collectively.
These causes affected different regions differently in the 1990s, with Europe having as much as 9.8% of degradation due to deforestation, while the impact of this on Oceania and North American was minimal, with only 1.7% and 0.2% of land affected respectively. Europe, with the highest overall percentage of land degraded(23%), also suffered from over-cultivation (7.7%) and over-grazing (5.5 %). In contrast, Oceania had 13% of degraded farmland and this was mainly due to over-grazing (11.3%). North America had a lower proportion of degraded land at only 5%, and the main causes of this were over-cultivation (3.3%) and, to a lesser extent, over grazing (1.5%).
Overall, it is clear that Europe suffered more from farmland degradation than the other regions , and the main causes there were deforestation and over- cultivation.
一、题目类型：
混合图=1饼+1表
二、题目简要内容：
饼图-全球范围内土地退化原因;
表图-三个区域土地退化原因
三、关注点：
土地退化
四、素材积累：
Degradation n.退化
Deforestation n.滥砍滥伐
Degrade n.退化
Over-grazing n.过度放牧
Over-cultivation n.过度耕作
Clearance n.清除，清理
Constitute n.占，构成
Account for v.占，导致
五、论据积累：
1. 本题为混合图，饼状图与表格图混合，考生要按照土地退化比例大小的顺序进行描述，由大到小。小作文图表题考生要用具体数据来支撑自己的写作。
2. 时态的使用也是值得注意的。饼状图涉及目前的状况，使用一般现在时，而表格中有明显的时间the 1990s，因此在描写时，使用一般过去时。
3. 每幅图各写一段，重点描述图中体现的主要趋势和信息。结尾指出两幅图之间的关系，进行比较或对比。如果没有直接关系，结尾简要总结两幅图的主要特点就行。
结构分析：
第一段：
第一段第一句话是改写题目，指出饼状图中的主要信息。
The pie chart shows that there are four main causes of farmland becoming degraded in the world today.
The pie chart shows that…. 饼图描述的是…
degraded 退化
接下来三句话具体分析饼状图中信息，用具体数据支撑。
Globally, 65% of degradation is caused by too much animal grazing and tree clearance, constituting 35% and 30% respectively. A further 28% of global degradation is due to over cultivation of crops . Other causes account for only 7% collectively.
grazing 放牧
tree clearance 滥砍滥伐
global degradation 全球退化
be due to 由于，起因于
over cultivation 过度开垦
account for 占
collectively 共同地，集体地
文中以百分比为主语，分别用了is caused by和is due to这两种表达方式比较好一些。
不过文中的show与原题目中的show重复，不能一味的重复，否则会失分。
degraded=degradation
farmland=agricultural land
第二段：
先概括主要内容：不同原因影响不同地区的程度不同，然后具体分析。
(1)先写占百分比最多的欧洲，指出在deforestation方面，欧洲的9.8%要远远大于大洋洲的1.7%和北美洲的0.2%。
These causes affected different regions differently in the 1990s, with Europe having as much as 9.8% of degradation due to deforestation, (2)描述时可把前者和后两者进行对比，文中用while引导的比较状语从句来进行对比。while the impact of this on Oceania and North American was minimal, with only 1.7% and 0.2% of land affected respectively. Europe, with the highest overall percentage of land degraded(23%), also suffered from over-cultivation (7.7%) and over-grazing (5.5 %).
文中首句these causes开头，指代上一段four main causes,起到了承上启下的作用。
(3) 描述完欧洲之后，接下来描述的是大洋洲，先写指出土地退化的总比率，然后写出主要原因，即为过度放牧。
In contrast, Oceania had 13% of degraded farmland and this was mainly due to over-grazing (11.3%).
(4) 最后写土地退化比例最低的北美洲，首先指出总比例，之后按照严重程度的顺序来写。North America had a lower proportion of degraded land at only 5%, and the main causes of this were over-cultivation (3.3%) and, to a less extent, over grazing (1.5%).
结尾段：
总结主要内容，即指出欧洲在三大地区中遭受土地退化的情况最严重，主要原因为滥伐森林和过度耕种。
Overall, it is clear that Europe suffered more from farmland degradation than the other regions , and the main causes there were deforestation and over- cultivation.
it is clear that…. ...明确，清楚
参考译文：
饼状图显示了当今世界农田退化的四个主要原因。在全球范围内，65%的退化是由过度放牧和滥砍滥伐导致的，分别占35%和30%。另外28%的全球退化是由于农作物的过度耕作。其他原因只占总量的7%。
这些原因在90年代对不同地区造成了不同程度的影响。欧洲多达9.8%的退化是由于滥砍滥伐，而大洋洲和北美洲受此影响相对较小，分别只有1.7%和0.2%的土地受影响。欧洲土地退化的总比率最高(23%)， 除滥砍滥伐外也受害于过度耕作(7.7%)和过度放牧(5.5%)。与此不同的是，大洋洲有13%的土地退化，其主要原因是过度放牧(11.3%)。北美洲土地的退化比例较低，只有5%,主要原因是过度耕作(3.3%),其次是过度放牧(1.5%)。
总之，我们可以看到，和其他地区相比，欧洲的农田退化最严重，其主要原因是滥伐森林和过度耕种。
