1.C由下文可知是说在自然界一切都可再次使用。因为主语 ererylhing与use是被动关系，故用被动语态且Ih语动例用单数形式故答案为C项。
2.B 考查不定代同。another另一，又一;other其余的，其他的;the other两者中另一个；others其余的人或物，后不跟名词。由句意可知答案为B项。
3.B考查定语从句。先行同为bags,且关系词在从句中作主语，故答案为B项。
4.A考查谓语动词的时态和语态。由and可知前后为并列成分，设空处与kills为并列谓语，故选A.
5.D when当…的时候;whether是否;why为什么;if如果。根据前后句可知答案为D项。
6.C ,因为rubbish是不可数名词，故用it代替。
7.A 考査连词。句意:在地球上，像水和树木这样的自然资源比较丰富，但这些资源并非是取之不尽的。根据句意可知前后是转折关系，故用连词but。
8.C 考查比较级。由than可知用比较级。
9.B 考查动词短语辨析。cut out裁_IV;cut down砍伐;cut in插嘴;cut up切碎。
10.D 本句中it为形式主语，后应填不定式作真正的主语。
