问题                             Reducing Waste Food
    Experts in the food industry are thinking a lot about trash these days. Restaurants, colleges, hospitals and other institutions are compensating for the rising costs of waste in novel ways. Some are tracking their trash with software systems, making food in smaller amount or trying to cut down on trash-hauling costs. Roughly 30 percent of food in the United States goes to waste, costing some $48 billion annually, according to a Stockholm International Water Institute study. A 2004 University of Arizona study estimated that 40 to 50 percent of food in the United States is wasted. Freshman students at Virginia Tech were surprised this year when they entered two of the campus’s biggest dining hails to find there were no cafeteria trays. 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 canteen, 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 carrying out a program to install food-only trash carts. The food waste is collected in biodegradable (可生物 降解的) bags and given to the city to use as compost (肥料). 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 (垃圾掩埋场). But food waste costs about $ 48 a ton to haul.
    Cutting back on the waste can require spending money on software and training. LeanPath, based in Portland, Ore. , sells a software system to track food being thrown out. Steve Peterson, head chef at the MGM Grand hotel in Las Vegas, said he was surprised when he installed the LeanPath system and saw the value of food that was going out the back door. To cut costs, Peterson decided to reduce serving sizes. He said customers weren’t bothered by the switch, which has helped him lower food waste by between 15 to 20 percent over 18 months. [br] What kind of measure has been taken to cut food waste?
选项 A、Making cafeteria at collage and universities trayless.
B、Using software system to trace the location of the trash.
C、Trying to remove the food waste little by little.
D、Charging higher prices for smaller amount of food.
答案 A
解析 推理判断题。由题干中的measures定位到第一段第三句和第二段。第二二段中说：大学为了节省开支，减少食品浪费，取消了食堂的托盘。所以[A]为正确答案。第一段第三句提到的软件系统是用来记录食品废物的，而不是一直跟踪废物垃圾的位置，排除[B]；减少运送的开支并不能是说一次一点地运送，所以排除[C]；文章说小份额的食品可以减少浪费，但并没有说同时将价格提高，所以排除[D]。
