【分析】
首先通读全文理解文章主旨:介绍亚马逊雨林的现状及面临的问题,需结合语境、句子结构和词汇变形规则选词填空。解题步骤为:1. 分析每个空的句子成分,确定所需词性或短语类型;2. 结合方框内词汇,匹配符合语境的词;3. 根据句子时态、主谓一致、形容词最高级、副词变形等规则,调整词汇的正确形式;4. 确保每个词汇仅用一次。

2. 第二空:此处需名词性成分作主语,结合语境“让雨林生病”,方框内climate change(气候变化)符合要求。
3. 第三空:结构为“one of + the + 形容词最高级”,方框内wet的最高级为wettest,结合常识亚马逊是世界最湿润的地区之一,故填wettest。
4. 第四空:句子主语为复数People,需表示“砍伐”的动词短语,cut down意为“砍倒”,符合“砍树取木材”的语境,主语为复数,一般现在时用原形,故填cut down。
