语篇解读：本文是一篇说明文，以密西西比河为例介绍了河流对人们的生活有重要作用，但随着城市规模的扩大和工业数量的增加，河流受到了严重的污染，所有国家应该行动起来阻止河流继续受到污染。
1．flowing 考查非谓语动词。句意：每个国家都至少有一条河流经其国土，这在其人民的生活中扮演重要角色。river 与flow之间是逻辑上的主谓关系，表示主动，用现在分词做后置定语，故填flowing。
2．its 考查代词。句意参考上题解析，修饰名词people用形容词性物主代词，故填its。
3．have used 考查时态。句意：自古以来，人们就利用河流作为交通工具。时间状语Since the beginning of history表明此处使用现在完成时，故填have used。
4．longest 考查形容词。句意：密西西比河是美国最长的河流，它在历史上对美国人民产生了巨大的影响。定冠词the修饰形容词最高级，故填longest。
5．greatly 考查副词。句意参考上题解析，修饰动词influenced用副词，故填greatly。
6．to 考查不定式。句意：河流为沿岸居民提供了饮用、种植庄稼和娱乐的机会。此处表示目的，应该用不定式做目的状语，故填to。
7．who/that 考查定语从句。句意参考上题解析，先行词为those，指人，关系词在定语从句中作主语，故填who/that。
8．As 考查状语从句。句意：随着城市规模的扩大和工业数量的增加，河流受到了严重的污染。此处表示“随着”，故填As。
9．decisions 考查名词。句意：它敦促所有国家做出决定并立即开始行动以阻止它受到污染。作make的宾语用名词，decision是可数名词，此处用复数表示泛指，故填decisions。
10．being polluted 考查非谓语动词。句意参考上题解析，介词from后接动名词作宾语，it与pollute之间是被动关系，故填being polluted。
