题目解答
答案
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．
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．

解析
考查要点：本题主要考查动词时态、副词用法、冠词、连词、不定式、比较级、定语从句、形容词选择、名词形式、形容词与系动词的搭配等语法知识。
解题核心：结合上下文语境，分析句子结构，判断空格处所需词性及形式。
关键思路：
- 时间状语（如In 1969）提示动词时态；
- 最高级前需加定冠词the；
- or表示选择关系；
- 不定式作主语补足语；
- 比较级需加er或用more；
- 定语从句关系词的选择；
- 形容词与分词形式的区分。
61. was
关键点：根据时间状语In 1969，句子描述的是过去的事情，需用一般过去时。
解析：主语为单数形式it，故填was。
62. actually
关键点：修饰动词caught fire需用副词，actual是形容词，不能作状语。
解析：填actually。
63. the
关键点：most outstanding是最高级，需加定冠词the。
解析：填the。
64. or
关键点：not...or表示“不是……就是……”，表示选择关系。
解析：填or。
65. to reduce
关键点：It takes...to do是固定句型，to do作主语补足语。
解析：填to reduce。
66. cleaner
关键点：than提示比较级，clean的比较级为cleaner。
解析：填cleaner。
67. that/which
关键点：habit是先行词，定语从句缺主语，需用关系代词that/which。
解析：填that/which。
68. amazing
关键点：stories是物，需用现在分词转形容词（表示“令人惊叹的”）。
解析：填amazing。
69. changes
关键点：are是系动词，主语需用复数名词，change的复数为changes。
解析：填changes。
70. patient
关键点：be后接形容词，patient（耐心的）作表语。
解析：填patient。
