问题     There’s a world paper shortage. There’s a national bottle【C1】______, and we’re running out of raw materials like timber and tin—or so the papers say. Well, I’ve just emptied my shopping basket after my【C2】______shopping trip and it was full of things made from these【C3】______materials. Half of what I’d bought I threw away at once; all those unnecessary paper bags, plastic bags, fresh【C4】______paper and old newspapers they put the food in nowadays.
    Modern packaging makes shopping cleaner and more convenient, but at what【C5】______? Every time you throw away a paper bag you’re throwing away part of a tree—and trees don’t grow【C6】______! At this rate there soon won’t be any trees left, and then what shall we do?
    Perhaps we’ll learn to do what my mother did. She used to keep a store of paper bags in a kitchen【C7】______and use them again and again for her shopping. Most goods were sold【C8】______in those days. And the shopkeeper weighed out the amount you wanted.
    Of course, liquid goods have always been【C9】______in bottles or cans, but why can’t we use them more than once? If we【C10】______all our bottles we would save on the raw materials and energy needed to make new ones. It’s time we started to think seriously about the growing shortage of raw materials in the world today.
    A. drawer B. seldom C. weekly D. reused
    E. cost F. verify G. overnight H. wrapping
    I. enclosed J. loose K. sold L. shortage
    M. scarce N. partial O. ban
【C5】
选项
答案E
解析 此处应为名词，作介词at的宾语。从上下文的内容可以推断，cost一词最适合。at what cost意为“以什么代价”。
