【分析】
这道题分为选词填空和判断正误两部分。解题时，先处理选词填空：通读短文理解每段大意，结合空格的语法结构、语义及方框内单词的词义，再根据固定搭配、动词形式变化（如不定式、第三人称单数等）确定答案；判断正误题需逐题定位原文对应语句，仔细核对题干与原文信息是否一致，避免细节偏差。
【解析】
（一）选词填空：
1. 固定搭配“do one's best to do sth.”（尽最大努力做某事），结合语境“保持空气清洁”，故填to keep；
2. 前文提到人们用树制作物品，列举了椅子、火柴，方框中paper（纸）符合语境，故填paper；
3. should后接动词原形，结合语境“种更多树”，故填plant；
4. 主语all plants and animals是复数，结合语境“需要水”，故填need；
5. 主语dirty water是不可数名词，谓语动词用第三人称单数，结合短语“come out（排出）”，故填comes；
6. 固定搭配“do what one can to do sth.”（尽所能做某事），结合语境“节约用水”，故填to save。
（二）判断正误：
1. 原文第一段“But now the air pollution is getting worse and worse.”与题干一致，故填T；
2. 原文第一段“Cars, coal and factories all make the air dirty.”与题干一致，故填T；
3. 原文第二段“They give us fruit and nuts.”说明树木可提供食物，题干表述错误，故填F；
4. 原文第三段“Without water there can be no life on the Earth.”与题干一致，故填T；
5. 原文第三段“There are still many people who have no clean water to drink.”说明水资源不足需节约，题干表述错误，故填F。
