Because paper of all kinds is the billets single component of municipal trash, many municipalities have tried recycling to reduce the cost of wash disposal.

kinds在这里不指纸张,虽然中心词是paper,但后面是将市政当局如何回收来降低垃圾处理成本,所以把because从句简化就是paper is the billets single component of...就是说纸是trash的component,即paper是because的中心词,这才是注意的关键,单数不可数名词。 另外,从句意理解,tried to recycle和tried recycling意思截然不同,前者是指市政当局“努力回收”,似乎后面的不定式补语之前应该有一个recycle的宾语,比如recycle it (paper); 要不然就成了"许多市政当局努力回收来降低。。。“。用tried recycling是指”尝试回收(的方法)来降低成本..."。显然后者更加明确.
