【分析】本题为选词填空补全短文题，解题思路为：先明确方框内各单词/短语的含义，再结合每个空所在句子的上下文语境、逻辑关系（如因果、转折、递进等），以及句子的语法结构（如主谓一致、介词搭配等），选择符合要求的短语，确保语句通顺、逻辑连贯。
【解析】1. 句意为“澳大利亚温暖的海滩是每年在此产卵的海龟的家园”，“be home to”表示“是……的家园”，主语beaches为复数，故填are home to；2. 句意为“它们在保持海洋健康中起作用”，“play a part in”表示“在……中起作用”，主语they为复数，故填play a part in；3. 句意为“塑料污染与它们的死亡有关”，“be connected with”表示“与……有关”，主语pollution为不可数名词，be动词用is，故填is connected with；4. 前文提到塑料污染导致海龟死亡，后文说各国采取措施，此处表“因此”，故填For this reason；5. 前文介绍熊猫是中国国宝，后文补充说明其主要食物是竹子，此处表递进说明，故填In fact；6. 前文说熊猫通过粪便传播种子，后文说新竹子能生长，此处表原因且后接代词this，故填Because of；7. 前文强调熊猫的重要性，后文说它们易受伤害，此处表转折，故填However；8. 句意为“我们应该做很多事来保护它们”，表目的且后接动词原形，故填in order to。
