问题     Experts in the food industry are thinking a lot about trash these days. Food waste has been a serious problem for restaurants and grocery stores—with millions of tons lost along the way as crops are hauled hundreds of miles, stored for weeks in refrigerators and prepared on busy restaurant assembly lines.
    Restaurants, colleges, hospitals and other institutions are compensating for the rising costs of waste in novel ways. " We have all come to work with this big elephant in the middle of the kitchen, and the elephant is this ’ It’s okay to waste’ belief system," said Andrew Shackman, president of LeanPath, a company that helps restaurants cut back food waste.
    Freshman students at Virginia Tech were surprised this year when they entered two of the campus’s biggest dining halls to find there were no cafeteria trays. " You have to go back and get your silverware and your drink, but it’s not that different," said Caitlin Mewborn, a freshman. "It’s not a big deal. You take less food, and you don’t eat more than you should. " Getting rid of trays has cut food waste by 38 percent at the cafeterias, said Denny Cochrane, manager of Virginia Tech’s sustainability program.
    Before the program began, students often grabbed whatever looked good at the buffet(自助餐), only to find at the table that their eyes were bigger than their stomachs, he said.
    That same phenomenon often happens at Oregon’s Portland International Airport. Busy travelers often discard half-eaten meals into trash cans, adding dozens of tons of waste that the airport must pay the city to haul away. Now the airport is working on a three-year-old program to install food-only trash cans. The food waste is collected in biodegradable(能生物降解的)bags and given to the city to use as compost(堆肥), said Stan Jones, environmental protection manager at the airport.
    Besides being environmentally friendly, the changes may save the airport money. It costs about $ 82 to have one ton of trash hauled from the airport to the city landfill. But food waste costs about $ 48 a ton to haul. Last year, the airport was able to separate 165 tons of food from the trash stream, which would add up to $5,600 in hauling fees alone.
What is the impact of the program of Oregon’s Portland International Airport?
选项 A、It helps the airport to keep a friendly environment.
B、It increases compost used in the city landfill.
C、It reduces the cost on hauling trash from the airport.
D、It promotes the application of biodegradable bags.
答案C
解析 推理判断题。本题考查俄勒冈波特兰国际机场所运行项目的影响。由定位句可知，该项目可以帮助机场削减开支，我们可以从下文中找到具体是哪方面的开支。由本段后几句可知，运一吨垃圾的费用比运一吨食品垃圾的费用要高，而该项目可以将食品垃圾从垃圾中分离出来，从而节约了运输垃圾的成本，故答案为C)。A)“它帮助机场保持一种友好环境”和D)“它促进了能生物降解的袋子的应用”原文均未提及，故排除；B)“它增加了用在城市垃圾填埋场的堆肥”是对原文的曲解，堆肥是用于城市的，不是用在城市垃圾填埋场，故排除。
