BBCC解析文章讲述了随着油价的不断上升，美国校车的运行也受到了影响，正计划减少校车的数量，这样一来有好处也有坏处。1.推理题。根据第二段后两行可知今年的油价是去年的两倍了，说明油费大大增加了。2.推理题。根据第三段最后三行Bus routes are being redrawn or, in some cases, canceled. Some areas are buying buses that use natural gas or other alternative fuels.说明高油价影响了校车的运营。3.细节题。根据文章最后一段第一行It could also get more children to walk or bicycle to school.可知
