饼图一直是雅思小作文写作中常见的一种形式，新东方网给大家详细讲解一下!

首先我们要知道饼形图与柱形图或者是线形图截然不同的是它没有横轴与纵轴，而是以饼形的分割来表示百分比，因此我们可以用三步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。

接下来就跟着小哥哥一起看看饼图的写作范例吧~

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.

由于饼图主要以比例说明和数字列举为主，我们需要在写作前准备好以下素材：

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".
