先描述面积最小的扇形

朗阁海外考试研究中心在此提醒考生，在这种写法中有一个前提，也就是这块扇形最小的面积代表的是"positive"的含义。

以下我们就来看一个例子：

Write a report for a university lecturer describing the information below.

? You should write at least 150 words.

? You should spend about 20 minutes on this task.

In 1945 only 30% of women completed their secondary education and 1% went on to a first degree. No women had completed post-graduate studies. This situation had changed radically by 1995. In 1995, 90% of women in Someland had completed secondary education and of those, half had graduated from an initial degree and 20% had gone on to postgraduate studies. At the other end of the scale we can see that by 1995 all girls were completing lower secondary, although 10% ended their schooling at this point. This is in stark contrast with 1945 when only 30% of girls completed primary school, 35% had no schooling at all and 35% only completed the third grade.

若采用这种写法时，必须注意的是2个饼图在转换时必须有"过渡句"，如第2个下划线的句子，来引导后面的数据。

采用折线图的写法来写饼图

当饼图的数据按照时间变化时，我们可以将其转换为折线图的方式来安排数据，比如：

You should spend about 20 minutes on this task.
