解析：
本题是本单元Grammar核心考点，考查基数词和序数词的区分用法：基数词用来表达数量、时刻等概念；序数词用来表达顺序，含义为“第几”，前面通常搭配定冠词the或者形容词性物主代词。逐空分析如下：
1. 第1空后接复数名词floors，表达大楼总共有30层的数量含义，用基数词thirty。
2. 第2空表达“住在第2层楼”的顺序含义，用序数词second。
3. 第3空表达时刻“7点10分”，时刻直接用对应基数词表达为seven ten。
4. 第4空是固定结构the+序数词+to do sth，表示“第几个做某事的人”，此处表达“第一个到校”，用序数词first。
5. 第5空表达日期“1月21日”，日期的日期部分要用序数词，21对应的序数词是twenty-first。
6. 第6空表达“第12个生日”的顺序含义，12对应的序数词是twelfth。
7. 结合常识，中秋节是中国农历第八个月的第十五天，第7空表达“第15天”用序数词fifteenth，第8空表达“第8个月份”用序数词eighth。
