阅读理解。

     There was more evidence the effects of high oil prices on the transportation industry.

     Automakers reported further drops in sales of tracks and SUVs (sport utility vehicles) in the United States

Big, fuel-hungry vehicles brought in big profits-until Americans faced big costs for fuel now they want smaller

and more fuel-efficient cars. The head of General Motors, Rick Wagoner, says the prices are changing consular

behavior. G.M sales in the United States dropped 30%from last year. The Ford Motor Company had a 19%

drop.

     General Motors announced it will close four truck factories in North America and expand car production.

It may also see its Hummer division. Hummers are military-like vehicles. But Rick Wagoner said G-M will go

forward with plans to make the Chevy Volt, a car powered mainly by electricity. He said it will be available no

later than the end of 2010.

     Still, new findings show that Americans are driving less. The Federal Highway Administration says the

number of kilometers traveled on public roads has dropped since late 2006.

     Many people may be driving less because of high gasoline prices But transportation officials worry that less

demand for gasoline will mean shortages of money from fuel taxes that support reads. Use of public

transportation, though, is up. The American Public Transportation Association says it increased three percent

this year.

     High fuel prices are also affecting air travel. The International Air Transport Association expects the

industry to lose at least two billion dollars this year, mainly because of prices for jet fuel. This week more air,

carriers in the United States announced plans to cut flights and jobs and remove older. Less fuel efficient planes

from service Continental Airlines said record-high fuel prices have produced the worst crisis (危机) for the

industry since 2001.
