【分析】
要解决这道题，我们需要先回忆英语序数词的构成规则：
1. 1、2、3的序数词是特殊变化，分别对应first、second、third；
2. 一般基数词变序数词直接加th，但部分单词有特殊变形：如5（five）变fifth（ve变f加th），8（eight）变eighth，9（nine）变ninth（去掉e加th），12（twelve）变twelfth（ve变f加th）；
3. 十几的序数词，除特殊变化的，一般在基数词后加th，如19（nineteen）变nineteenth；
4. 整十的序数词，要把基数词末尾的y变为ie再加th，如20（twenty）变twentieth，40（forty）变fortieth；
5. 几十几的序数词，只需将个位部分变为序数词，十位保持基数词形式，如32（thirty-two）变thirty-second，48（forty-eight）变forty-eighth。
我们根据这些规则，逐个对应题目中的缩略形式写出完整序数词即可。
