Complete the following sentence with a (compound) word derived from the one(s) given in bracket.
If you （ ） the used things, such as bottles or sheets of paper, you process them so that they can be used again. (cycle)
【正确答案】：RECYCLE
【题目解析】：
根据前文you代词，后文the used things名词，可知空格处应该填动词，根据意思后面用用过的东西再用，应该是recycle回收，再循环。句意：如果你回收用过的东西，如瓶子或纸张，处理一下它们，以便再次使用。
