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 do we learn about Oregon’s Portland International Airport?
选项 A、The travelers there have to pay the airport to haul away waste.
B、The food waste there will be used as compost in the city.
C、Food-only trash cans were installed there 3 years ago.
D、The travelers there are not allowed to discard half-eaten meals.
答案B
解析 事实细节题。本题考查俄勒冈波特兰国际机场所运行项目的细节。定位段提到，该机场以前食品垃圾的情况非常严重，而机场现在正在运作一个为期三年的项目来安装只用于倾倒食物的垃圾箱。食品垃圾被收集到能生物降解的袋子中，然后交给波特兰市用于堆肥，故答案为B)。A)“旅客们必须付费给机场以运走垃圾”与原文意思不符，原文提到的是机场不得不付费给这座城市来运走垃圾，故排除；C)“机场3年前就安装了只用于倾倒食物的垃圾箱”是对a three—year—old program to install food—only trash cans的曲解，此处意思为这个项目要持续三年才能完成，也就是说三年后才能安装完只用于倾倒食物的垃圾箱，而不是三年前就安装好了，故排除C)；D)“不允许旅客把吃了一半的食物丢掉”与原文意思不符，故排除。
