三招搞定BEC写作图表作文饼状图

招数一：比较级和最高级

◆ 只针对一个饼图中的一个组成部分进行描述

The most popular mobile phone color is black.

The second most common color is white.

◆ 针对一个饼图中两个组成部分进行对比描述

White is considerably more common than red.

其中，根据饼图中不同份额之间的差异程度不同，副词considerably可以替换为substantially，a lot，far，much，somewhat，significantly，slightly和fractionally (微乎其微地，很细微地)等。

此外，A比B不仅可以多或好，还可以不如对方，甚至可以用同级比较的句型来对比两个事物。例如：

Red is far less popular than black.

Black is about twice as common as white.

招数二：确定性地描述某一事物在该饼图中所占份额

描述饼状图与柱状图和线形图另一个比较明显的区别是饼图中会非常清晰地标明每一份所占的比例是多少。所以，从语言学习的角度来看，掌握描述份额的句型就是重中之重了。可以引出份额的动词或动词词组有：be，make up，constitute，account for等。同时，可以使用定语从句relative clause (which + appropriate verb)引出所要描述的份额。例如：

Black, which is 56.11%, is considerably more common than red, which makes up 12.72%.

Black, which constitutes 56.11%, is about twice as popular as white, which is 28.05%.

The other colors, which constitute 3.12%, are considerably less popular than red, which accounts for 12.72%.

招数三：使用括号brackets ( )

Black (56.11%) is considerably more common than red (12.72%).

The other colors (3.12%) are considerably less popular than red (12.72%).
