【分析】
本题分为语法填空和阅读理解选择题两部分。语法填空需根据句子结构、语法规则（如比较级、最高级、副词用法）填写单词正确形式；选择题需结合原文细节和词义猜测选出答案。
【解析】
1. 句中出现比较级标志词than，需用形容词big的比较级形式bigger，故填bigger。
2. 修饰名词way需用形容词，范围是“among birds（三者以上）”，需用special的最高级形式，即the most special，故填the most special。
3. so...that结构中，需用副词修饰动词move，fast的副词形式仍为fast，故填fast。
4. 细节理解题：A选项原文是“not much bigger than a bee”，并非比蜜蜂小，错误；B选项文中未提及，错误；C选项是hover像直升机，而非移动速度和直升机一样，错误；D选项原文提到飞行时发出嗡嗡声，正确，故选D。
5. 词义猜测题：根据后文“That means they can stay in one place in the air.”可知，hover意为“在空中停留”，对应B选项，故选B。
【答案】
1. bigger；2. the most special；3. fast；4. D；5. B
【知识点】
形容词比较级、形容词最高级、阅读理解细节理解
