A(2025·江苏连云港)
Hello from nature’s foodies
As a proud grizzly bear, I say hello from Alaska. We eat anything we can get our paws on. One of my favourite meals is catching fresh salmon. There’s nothing quite like the pleasure of a stomach full of fresh fish!
续表
I'm a blue whale. I may eat up to 3.6 million krill(磷虾) per day! You may wonder why such huge animals live on such tiny food? It's because our mouths only have rows of baleen(鲸须). It lets water flow out while holding in tiny things.
I'm a hummingbird. We eat flower nectar(蜜). We fly around a few thousand flowers each day to get as much food as possible. As we move our wings really fast, we burn through energy fast. So we need to keep feeding.
Hello~from~a~sloth~in~the~South~America! Our favourite food? Low-energy leaves! Do we eat a lot? No. We slow-movers don't need a lot of energy. Even our stomachs work so slowly that after a meal, we're too tired to do anything but...sleep!

【分析】
做此类阅读理解题时，需先通读全文把握文章主题，再针对各小题问题定位原文对应段落，对比原文信息与选项内容选出最佳答案。第1题是细节理解题，需定位蓝鲸的相关段落查找其以微小生物为食的原因；第2题需分别定位蜂鸟和树懒的食量描述，分析两者食量的决定因素；第3题是文章出处题，需根据文章介绍动物习性的主题判断所属杂志板块。
【解析】
1. 细节理解题：定位蓝鲸段落，原文明确说明“You may wonder why such huge animals live on such tiny food? It's because our mouths only have rows of baleen(鲸须).”，可知蓝鲸以微小生物为食是因为口中只有鲸须，对应选项C。
2. 细节理解题：定位蜂鸟段落，原文提到蜂鸟“move our wings really fast, we burn through energy fast. So we need to keep feeding”，说明其食量由快速消耗能量的活动决定；定位树懒段落，原文指出树懒“slow-movers don't need a lot of energy”，说明其食量由缓慢的活动决定，两者均与日常活动相关，对应选项C。
3. 文章出处题：全文介绍四种动物的饮食习性，属于野生动物相关内容，最可能来自杂志的“Wildlife（野生动物）”板块，对应选项A。
