图中曲线表示 Surf City 政府在一九八八年中累计花费的金额，单位为百万美元。例如，到二月初约已花费 $.5$ 百万美元，到四月底约已花费 $2$ 百万美元。六月、七月和八月大约一共花费了多少百万美元？

The graph below shows the total accumulated dollars (in millions) spent by the Surf City government during 1988. For example, about $.5$ million had been spent by the beginning of February and approximately $2$ million by the end of April. Approximately how many millions of dollars were spent during the summer months of June, July, and August?

$1.5$

$2.5$

$3.5$

$4.5$

解答：

图显示的是累计花费，所以六月、七月、八月的花费等于这段时间累计值的增加量。

从图上看，六月开始时累计值略多于 $2$ 百万美元，八月结束时略多于 $4.5$ 百万美元，差约为 $4.5 - 2 = 2.5$ 百万美元。

所以正确答案是 B。

The graph gives the total accumulated spending, so the amount spent during June, July, and August equals the accumulated total at the end of August minus the accumulated total at the beginning of June.

The curve is at a bit more than $2$ million at the beginning of June and a bit more than $4.5$ million by the end of August. The difference is about $4.5 - 2 = 2.5$ million.

Thus, the correct answer is B .
