解析:
【分析】本题为英语单词适当形式填空题,需结合语法规则、固定搭配及词性转换解题。具体思路:1. 分析介词后接动词的形式;2. 判断主语单数以确定谓语动词形式;3. 根据名词所有格后接名词的规则转换词性;4. 牢记固定搭配中介词后的非谓语形式;5. 区分动词与介词形式;6. 掌握固定句型中不定式的用法。
【解析】1. 固定搭配be known for中,for是介词,介词后需接动词的动名词形式,故将solve变为solving;2. 主语为动名词短语Burning fuels,视为单数,一般现在时谓语动词用第三人称单数形式,故cause变为causes;3. 名词所有格student's后需接名词,absent是形容词,其名词形式为absence;4. 固定搭配prevent...from...中,from是介词,后接动词的动名词形式,故将spread变为spreading;5. 此处需介词表示“包含”,include是动词,其介词形式为including;6. 固定句型It is + adj + of sb + to do sth中,it为形式主语,真正主语是不定式,故用to return。
【答案】1. solving 2. causes 3. absence 4. spreading 5. including 6. to return
