解析：
【分析】
首先通读全文理解语境，结合方框内词汇及词性、句式规则，逐个分析空格需求：1. 第一空主语是指代雨林的单数it，需填表“是……家园”的短语，对应be home to的单数形式；2. 第二空需填导致雨林“生病”的原因，方框内climate change符合；3. 第三空是“one of + 形容词最高级”结构，需填wet的最高级；4. 第四空主语是people，需填表“砍伐”的动词短语原形；5. 第五空修饰动词harm，需填easy的副词形式。
【解析】
1. 主语it为单数，be home to表示“是……的家园”，一般现在时中be动词用is，故填is home to；
2. 结合语境，气候变化是导致雨林出现问题的原因，故填climate change；
3. “one of + the + 形容词最高级”表示“最……之一”，wet的最高级为wettest，符合雨林原本潮湿的特点，故填wettest；
4. cut down表示“砍伐”，主语people为复数，一般现在时用动词原形，符合人们砍树获取木材的语境，故填cut down；
5. 此处修饰动词harm，需用副词，easy的副词形式为easily，故填easily。
【答案】
1. is home to 2. climate change 3. wettest 4. cut down 5. easily
