雅思饼状图两天搞定！(2)

【拆招】

主体段二

Expenditure on resources such as books had increased to 20% by 1991 before decreasing to only 9% by the end of the period. In contrast, the cost of furniture and equipment saw an opposite trend. This cost decreased to only 5% of total expenditure in 1991 but rose dramatically in 2001 when it represented 23% of the school budget. Similarly, the cost of insurance saw a rising trend, growing from only 2% to 8% by 2001.

【解招】

本段是对其余三项的描述，它们都是排名其次的对象。根据三个被描述对象的趋势变化，先写resources(e.g.books)的花费呈“先上升、后下降”的趋势，然后通过in contrast这一表示相反的连接词引出furniture and equipment“先下降、后上升”的相反趋势，前后对比。最后，通过similarly,引出占比例最小的insurance，该对象同为整体上升的趋势，用“短语类句型搭配非谓语”的语法结构，将数据描述清晰。本段的衔接和过渡非常自然，值得深入研究。
