解析:
【分析】
这道题全部考查数词中序数词的用法,解题思路如下:1. 先判断语境:观察每个空格前都有定冠词the或者名词所有格(比如my sister's、my grandpa's),空格后接的是floor(楼层)、birthday(表第几个生日)、time(表第几次),这类表顺序的场景都需要使用序数词,不能用表数量的基数词。2. 再结合基数词变序数词的规则,对括号内给出的基数词做对应变形,注意特殊拼写规则:比如以ve结尾的基数词要改ve为f再加th,整十的基数词改y为ie再加th,几十几的数字只把个位改为序数词,十位保持基数词形式,避免拼写错误。
【解析】
1. 要表达“第五层楼”的顺序含义,基数词five对应的序数词为fifth。
2. 要表达“第二十二层楼”的顺序含义,几十几的序数词仅需将个位变为序数词,twenty-two对应的序数词为twenty-second。
3. 要表达“第九个生日”的顺序含义,基数词nine对应的序数词为ninth。
4. 要表达“第九十个生日”的顺序含义,整十基数词ninety变序数词需改y为ie加th,对应形式为ninetieth。
5. 要表达“第一百岁生日”的顺序含义,one hundred对应的序数词为hundredth。
6. 要表达“第八层楼”的顺序含义,基数词eight变序数词直接加h,对应形式为eighth。
7. 要表达“第十二个生日”的顺序含义,基数词twelve变序数词改ve为f加th,对应形式为twelfth。
8. 要表达“第二十个生日”的顺序含义,整十基数词twenty变序数词改y为ie加th,对应形式为twentieth。
9. 要表达“第四次”的顺序含义,基数词four对应的序数词为fourth。
10. 要表达“第四十个生日”的顺序含义,整十基数词forty变序数词改y为ie加th,对应形式为fortieth。
【答案】
1. fifth 2. twenty-second 3. ninth 4. ninetieth 5. hundredth 6. eighth 7. twelfth 8. twentieth 9. fourth 10. fortieth

【点评】
本题聚焦初中英语数词模块的核心基础考点,全部选取了序数词最常见的使用场景(楼层排序、年龄对应的第几个生日、动作发生的次数排序),考察方向常规,仅需要学生熟练掌握基数词转序数词的常规规则和特殊拼写即可完成,易错点集中在twenty-second、ninetieth、twelfth这类特殊拼写的序数词,平时要注意多积累特殊变形的数词拼写。
