Question (1) and (2) are based on the following data.
(1) For which year did total expenditures increase the most from the year before?
(2) For 2001, private school expenditures were approximately what percent of total expenditures?
选项
答案
(1)1998
(2)18.75%
解析
读图,先大致把握图表的信息:
图表标题:1987年~2001年公立学校和私立学校的支出(单位为10亿美元)
横坐标:年份
纵坐标:支出金额
图例:三条线分别表示总支出、公立学校支出、私立学校支出
注释:图中没有注释
(1)题目问的是:哪一年的总支出比前一年增长得最多?无须逐个计算两年支出的差值,只需观察折线的斜率,斜率大(折线陡峭)的即为两年的差值大。观察可知1997年~1998年之间的线段最陡峭,题目问的是哪一年比前一年增长最多,所以答案为1998年。
(2)题目问的是:在2001年。私立学校支出大约占总支出的百分之多少?根据2001年定位到图的最后一列,又再根据问题得出私立学校支出为30(10亿美元),总支出为160(10亿美元),所以私立学校占总支出的百分比为30/160×100%=18.75%。
