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(鲑鱼). There's nothing quite like the
pleasure of a stomach(腹部) full of fresh fish!
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(极小的) 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~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!

解析：
【分析】
本题为阅读理解题，需通过定位原文关键信息解答各小题：
1. 第21题：定位蓝鲸的段落，找到其以微小生物为食的原因，匹配对应选项；
2. 第22题：分别定位蜂鸟和树懒的进食量相关描述，分析影响进食量的因素；
3. 第23题：根据文章介绍动物食性的核心内容，判断所属杂志板块。
【解析】
21题：根据蓝鲸段落中的“It's because our mouths only have rows of baleen(鲸须). It lets water flow out while holding in tiny things.”可知，蓝鲸只有鲸须而非牙齿，只能滤食微小生物，对应选项C，故答案为C。
22题：蜂鸟段落提到“move our wings really fast, we burn through energy fast. So we need to keep feeding”，树懒段落提到“We slow-movers don't need a lot of energy”，二者的进食量均由日常活动（蜂鸟快速振翅、树懒行动缓慢）决定，对应选项C，故答案为C。
23题：文章核心内容是介绍四种野生动物的食性特点，属于野生动物主题，对应杂志的Wildlife板块，故答案为A。
【答案】
21.C；22.C；23.A
