具体而言,观察每张饼图的各类别所占比例,并比较两幅图之间的关系。不难发现在这两个年份food和cars是占家庭支出的最大的两个类别并且food和cars的总和占家庭支出比例的半数以上。
具体表达如下:
Food and cars made up the two biggest items of expenditure in both years. Together they comprised over half of household spending. Food accounted for 44% of spending in 1966, but this dropped by two thirds to 14% in 1996. However, the outlay on cars almost doubled, rising from 23% in 1966 to 45% in 1996.
理论上而言,按趋势和幅度分段写都是可以的,但为了数据信息处理更简便以及使表达上更精炼,我们在这里按变化幅度分段描述。
A. 变化幅度大的有restaurants, computers和books
Some areas changed significantly. Spending on restaurants doubled, climbing from 7% to 14%. The proportion of salary spent on computers increased dramatically from 1% in 1966 to 10% in 1996. However, as computer expenditure rose, the percentage of outlay on books plunged from 6% to 1%.
B. 变化幅度小的有petrol和furniture
Other areas remained relatively unchanged. Americans spent approximately the same amount of salary on petrol and furniture in both years.
