【题目解析】：41、【mistaken】原文“be”后面应该接动词的过去分词，“be mistaken”表示某人的误会、误解或弄错。则填入“mistaken”。
42、【endless】该空填形容词，根据原文意思应该是无穷尽的供应水，因此填入“endless（无止境的）”。
43、【covered】空格前面是“is”，则填入动词的过去分词，“is covered”意思是“被覆盖”。
44、【percentage】该空填名词，percentage是抽象的，前面可有形容词修饰，表示一定比例。percent前一般有具体数字，是具体的，表示具体比例。则填入名词“percentage（百分比）”。
45、【including】“____ (include)Spain, Italy and South Africa”作为定语，表示“包括......在内”，使用介词“including”。
46、【Surprisingly】“Surprising”单独放句首填副词“Surprisingly（令人惊讶地）”，注意句子开头要大写。
47、【getting】“____ (get) clean drinking water”作为定语，则填入“getting”。
48、【worse】根据后文的“warmer”判断填入比较级“worse”。
49、【uses】主语“Every person”是单数，则谓语动词使用单数形式，则填入“uses”。
50、【shocked】原文“be”后面应该接动词的过去分词，“be shocked”意思是“感到震惊”，则填入“shocked”。
