【分析】
本题为英语词汇运用题,需根据语境和语法规则用括号内所给词的适当形式填空。解题思路如下:
1. 第1题:空格前是疑问词how,考查“疑问词+动词不定式”的固定结构,作explain的宾语,需将动词reuse变为不定式形式。
2. 第2题:空格前是形容词white,形容词后需接名词,动词pollute需转换为名词形式。
3. 第3题:空格后是名词weather,修饰名词需用形容词,名词smog需转换为形容词形式。
4. 第4题:空格后是名词challenges,修饰名词需用形容词,名词globe需转换为形容词形式。
5. 第5题:主语the river是动作pollute的承受者,时间状语now表明用一般现在时,需用一般现在时的被动语态结构。
【解析】
1. 考查“疑问词+不定式”结构,how后接动词不定式作explain的宾语,故填to reuse。
2. 考查名词用法,形容词white后需接名词,pollute的名词形式为pollution,故填pollution。
3. 考查形容词用法,修饰名词weather需用形容词,smog的形容词形式为smoggy,故填smoggy。
4. 考查形容词用法,修饰名词challenges需用形容词,globe的形容词形式为global,故填global。
5. 考查一般现在时的被动语态,主语the river是pollute的承受者,时间状语为now,结构为“is+过去分词”,故填is polluted。

1. to reuse 2. pollution 3. smoggy 4. global 5. is polluted
