雅思写作小作文题型规律介绍之饼状图
饼图写作题目范例：
WRITING TASK 1:
You should spend about 20 minutes on this task.
* The charts below show US spending patterns from 1966 to 1996.
* Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
You should write at least 150 words.
饼形图与柱形图或者是线形图所截然不同的是它没有了横轴与纵轴，而以饼形的分割来表示百分比，但我们仍可以依照三步的审题分析法来进行观察：
Step 1: 观察共有几张饼图，以及它们之间的关系是什么(一般说来，雅思图表题中极少见到单饼图);
Step 2: 观察每张饼图中有哪几个区域，以及各个区域分别代表什么;
Step 3: 观察单个饼图中各区域间的百分比差异，以及相同区域在各个饼图间的百分比的比较或发展。
由于饼图主要以比例说明和数字列举为主，我们需要在考前准备好以下素材：
① 动词“占”的表达：
account for, hold, make up, take up, constitute, comprise, represent
② 百分比的表达
percentage，proportion, share, 某些情况下可以用rate，如literacy rate
③ 约数表达
the majority of, most of, a considerable number of, a minority of , just over…, slightly more than…/less than…, nearly half… 等
④ 确切数字表达
分数与百分比的转化：one third, two fifths，one tenth
常见表达：a quarter, a half
⑤ 句式
要灵活运用以上的词汇结合一定的句子，变换表达方式。
例：亚洲人口占世界比例近50%。
— Asia accounts for almost a half of world population.
— Nearly 50% of people in the world come from Asia.
— The percentage of Asian in the world population is slightly less than a half.
— Asia has the largest percentage of population in the world( approximately 50%).
⑥ 排序段
在列举饼图数据时，为了防止单调枯燥，我们常常运用排序的方式进行说明：
— China takes the lead in world population.
类似的表达还有“be leading, the majority, mostly, most等”
— Next comes food, whose percentage is higher than that of clothing.
类似的表达还有“follow”
— People seem to show no interest in reference books, which lies last in the percentage.
类似表达还有“fall behind other items, the lowest proportion”.
