中国商人网8月29日讯：（CNNMoney 8月28日讯By Catherine Clifford） 纽约（CNNMoney.com） 根据周二国家加油站信用卡消费发布的调查，石油价格继续下滑，从7月最高价下降了11%。
石油价格每加仑3.660美元，比前天的3.667美元下降了0.007美元。周四已经是连续的第5天零售石油价格下降。
AAA报告，自从7月17日石油价格达到4.114美元一加仑以来，这次石油价格又下降了至少45.4美分。
随着原油价格的大幅下降，石油的平均价格也随之下降。原油价格达到自7月11日以来的创记录的147.27美元，但是自从那时起，由于能源成本高，全球需求减少，石油价格下跌了18%。
州价格：
由于每个州和当地的汽油税不同，所以每个州的石油价格也不同，另外，每个州的石油价格是根据距离墨西哥湾的距离来确定的。
根据调查，只有两个州的石油价格保持在每加仑4美元，阿拉斯加的价格最高，达到了4.529美元一加仑，比昨天的4.546美元轻微下降了。夏威夷是石油价格第2高的，达到了每加仑4.386美元，比昨天的4.393美元轻微下降了。
内燃机
内燃机的燃料价格从昨天的每加仑4.283美元下降到4.275美元。去年内燃机燃料的价格上升了将近46%，那时的价格是每加仑2.930美元。由于交通运输，燃料价格推动了产品和服务的价格。
乙醇
随着以石油为基础的燃料价格不断攀升，许多美国人把乙醇作为“灵活燃料”车辆的动力。乙醇主要由谷物制成。 E85的价格从前天的每加仑3.030美元下降到了3.009美元。乙醇比一般的天然气要便宜，但是中西部地区才有乙醇。因为只有中西部地区盛产谷物，这些地区的谷物甚至是不外流的。（译者：中国商人网记者：章莉莉）

新闻原文：
NEW YORK (CNNMoney.com) -- Gas prices continued their slide, falling 11% from highs reached in July, according to a national survey of gas station credit card swipes released Thursday.
Gas was selling at $3.660 a gallon, a decrease of seven tenths of a cent from the previous day's price of $3.667, according to motorist group AAA and the Oil Price Information Service. Thursday's decline is the fifth consecutive day that retail gas prices have fallen.
Prices have fallen more than 45.4 cents since hitting a record of $4.114 on July 17, AAA reported.
The average price of a gallon of gas has been falling as crude oil prices have come sharply off their recent highs. Crude futures hit a record high of $147.27 on July 11 but have since fallen more than 18% as global demand slackened in reaction to the high energy costs.
While gas prices have fallen off their recent highs, however, prices at the pump are still 33% above the same time last year, when a gallon of gas cost $2.758.
State prices: Gas prices change from one state to the next due to differences in state and local gasoline taxes. In addition, gas prices vary by state according to how far the state is from oil and gas facilities in the Gulf of Mexico.
Gasoline remains above $4 a gallon in only two states, according to the survey. Alaska had the highest prices at $4.529 a gallon, down slightly from the previous day's price of $4.546. Hawaii was second at $4.386, down from $4.393 yesterday.
Missouri had the cheapest gas, with prices falling to $3.424 a gallon. South Carolina had the second least expensive gas, with a gallon costing $3.442.
Diesel: The average price for diesel fuel, which is used in most trucks and commercial vehicles, fell to $4.275 a gallon from $4.283 the previous day, according to AAA.
The price of diesel has risen almost 46% in the last year, when a gallon of diesel cost $2.930. Because it is used in transporting goods, the rise in the price of diesel fuel has pushed up the prices of products and services.
Ethanol: Many Americans have turned "flex-fuel" vehicles powered in part by ethanol as the price of petroleum-based fuels climbed to record levels in the past year.
The price of E85, an 85% ethanol blend, fell to $3.009 a gallon on average from $3.030 in the previous day, AAA reported.
Ethanol, made out of corn, is cheaper than regular gas, which is made from pricey crude oil. However, ethanol is only readily available in the Midwest, where much of the nation's corn is produced,and it's not even sold in some states.
Ethanol contains less energy than petroleum-based gasoline and burns less efficiently. Drivers of vehicles capable of running on ethanol or gasoline would pay about $3.959 a gallon to get the same mileage from ethanol as from regular gas, according to AAA's estimates.
