答案The line graph provides information about changes in price in the UK of three different food product groups from 1979 to 2009, and the overall trend in the consumer price index over this 30-year period. Overall, it is clear that prices increased for the three food product groups, despite fluctuations. Only the increase in the prices for fresh fruits and vegetables was significantly higher than the rise in the general consumer price index. A11 the lines on the graph have the same starting figure in 1979. Over the period, the consumer price index rose steadily from around 60 in 1979 to over 200 in 2009. Prices for sugar and sweets and carbonated drinks showed similar trends. Although their prices also rose, they were consistently below the consumer price index average after 1987. After many minor fluctuations, the price for sugar and sweets was 200 in 2009, higher than the final figure for carbonated drinks at 150. Prices rose sharply for fresh fruits and vegetables, particularly after 1989. From the same figure of about 60 at the start of the period, the prices finished at roughly 330 in 2009.
解析 本题为动态线形图，图中出现年份的变化。有四个数值的变化，但需要特别注意的是，四个数值中，三个属于食物，而另一条是consumer price index，即“消费价格指数”(CPI)。应将CPI数值作为参考对照，而不应该和其他三条混为一谈。
线形图中较为明显的特征是四个数值的起始位置几乎是一样的，且总体趋势都在增长(期间均略有少许波动)，但增长幅度略有不同。故行文时可将CPI作为参考线，分两段陈述，一段陈述高于CPI的fresh fruits and vegetables，另一段陈述低于CPI的sugar and sweets和carbonated drinks。
