分析 短文主要讲了无论遇到什么似乎是不可能解决的事情，一定要耐心并付出努力，就有可能成功！
解答 61．was，考查be动词，根据本段第一句In 1969，the pollution was terrible可知本段叙述的是过去发生的事情．the Cuyahoga River Cleveland在过去被污染地如此地严重，过去没有人能够想象倒这条河被清理干净．
62．actually，考查副词，本句中使用副词actually做状语修饰谓语动词caught fire，actual是形容词，不能在句中做状语，通常只做定语或者表语修饰名词．
63．the，考查冠词，本句横线后面的most是最高级的形式，所以使用the most outstanding的形式．
64．or，考查连词，句义：但是这条河流的改变不是几天或者几个月的事情．本句中的or"或者"表示选择的意思．
65．to reduce，考查固定搭配，考察固定句式：It takes sb some time to do sth做某事花了某人…时间；句中的不定式to reduce he industrial pollution and clean the water是句子真正的主语．前面的it是形式主语．
66．cleaner，考查比较级，句义：最后人们的努力得到了回报，现在这条河比以前更干净了．横线后面有than，说明横线上应该使用比较级的形式．
67．that/which，考查定语从句，本句是一个定语从句，先行词是a habit，定语从句中使用关系动词that/which指代先行词在句做主语．
68．amazing，考查形容词，现在分词转换的形容词常常修饰事物，过去分词转换的形容词常常修饰人或者与人有关的事物．横线后面是名词story，说明应该使用现在分词转换的形容词．
69．changes，考查名词，本句中谓语部分是系动词are，说明主语应该是一个复数形式的名词，所以使用changes．
70．patient，考查形容词，横线前面有系动词be，说明本句是一个祈使句be patient耐心一点．因为很多变化都是逐渐发生的，需要很多努力，我们要耐心一点．
点评 对于语法填空这类题，一是懂得分析句子结构，二是知道充当各个句子成分的词类或词性，从语法上确定答案，当然，对于某些固定搭配也要牢记，在平时的学习中要多积累这些词汇或短语，对于句子使用的时态语态也要通过语境进行确定．
