The United States has about 475,000 school buses-all painted yellow. Each day they carry more than
25,000,000 children, half of all schoolchildren in the country. But these buses, on average, use four liters of
diesel (柴油) fuel to travel less than sixteen kilometers. When the school year began last fall, diesel averaged
55 cents a liter nationally. The price nearly doubled, to a dollar and 8 cents, by the end of school in June.
Bob Riley speaks for the American School Bus Council. He says fuel prices for schools are not much
lower than others have to pay. As a result, schools are looking for ways to reduce transportation costs. Bus
routes are being redrawn or, in some cases, canceled (取消). Some areas are buying buses that use natural
gas or other alternative fuels. Other steps include fewer field trips and less travel by sports teams. And some
school districts (地区) may end any bus service not required by law.
Studies show that school buses are the safest form of transportation to and from school. The American
School Bus Council says cuts in bus service are bad for children and possibly the environment. It says
removing buses from the road will mean an increase in other vehicles transporting students. Spokesman Bob
Riley says another concern is that reducing bus services might reduce attendance.
But it could also get more children to walk or bicycle to school. And that would surely make people happy
at the National Center for Safe Routes to School. More kids walking or biking safely to school is the aim of a
three-year-old federal program, part of an international movement. The goal is to increase physical activity and
reduce air pollution. The United States will celebrate Walk to School Day on October eighth this year. But for
some students, high fuel prices could make every day a walk-to-school day.
