5.It can be concluded from the passage that _______.

　　A. rubbish is a potential remedy for the shortage of raw materials

　　B. local governments in the U. S. can expect big profits from recycling

　　C. recycling is to be recommended both economically and environmentally

　　D. landfills will still be widely used for waste disposal

　　Best Answer:C

　　詳解：答案C。在最后一段中，作者從兩方面論述了回收垃圾的好處，一是節(jié)約費用，二是有利于控制污染，保護環(huán)境。C項準(zhǔn)確地表達了這兩層含義。A、B兩項文章未提到。D項說法錯誤，因為政府在處理垃圾時首先想到的是回收利用，可見是回收而不是垃圾墳埋場將得到廣泛應(yīng)用。
