A
People throw rubbish on the beach and even into the ocean. The rubbish has become the "home" of hermit crabs (寄居蟹). Believe it or not, it is happening all over the world. Scientists have seen hermit crabs using bottle tops, parts of old light bulbs (灯泡), and even broken glass bottles.
Different from other crabs, hermit crabs have soft bodies, so they need to look for shells for protection. They first look at the shells' type, size, and colour. Then, they use their legs to check the inside of the shells to make sure they are the right size. As they grow, they give up their old shells and find bigger ones to live in.
However, "rubbish shells" can bring danger to hermit crabs. Plastic rubbish is often brighter in colour than shells. It might stand out against the background, so predators (捕食者) can find hermit crabs more easily. Also, the crabs may not get out and then die when they go into plastic bottles or old tires (轮胎).

答案：21-25 BBADD
解析：
21. 细节理解题。根据第一段内容"People throw rubbish on the beach and even into the ocean. The rubbish has become the 'home' of hermit crabs"可知，第一段点明的核心问题是寄居蟹将人类丢弃的垃圾当成了自己的住所。文中没有提到寄居蟹数量变多，排除A；C选项的描述不是第一段提出的核心问题，排除；D选项和原文科学家很容易观察到寄居蟹使用垃圾当住所的内容不符，排除，因此选B。
22. 词义猜测题。根据划线词前的句子"Hermit crabs have soft bodies"可知，寄居蟹的身体十分柔软，它们寻找贝壳的作用是护住自己柔软的躯体，因此"protection"的中文含义是“保护”，选B。
23. 细节理解题。根据第二段"Then, they use their legs to check the inside of the shells to make sure they are the right size"的内容可知，寄居蟹是用自己的腿来检查贝壳内部的尺寸是否合适，对应选项A。
24. 主旨大意题。通读全文可知，文章主要介绍人类随意丢弃的海滩、海洋垃圾，给寄居蟹带来了极大的生存威胁，作者的写作目的是向读者展示垃圾给寄居蟹造成的生存问题。文章核心不是讲述寄居蟹的趣味故事，排除A；文中没有介绍寄居蟹的物种重要性，排除C；文中也没有呼吁人们为寄居蟹制作新住所，排除D，因此选B。
25. 推理判断题。本文是一篇科普向的环保主题短文，这类内容最有可能出现在报纸的科普/环保板块，不会出现在故事书、旅游书籍或者时尚杂志中，因此选D。
