【序数词英语1到100】在英语中，序数词用于表示顺序或排名，如“第一”、“第二”等。掌握这些词对于日常交流、写作和学习都非常有帮助。以下是对英语中1到100的序数词的总结，并以表格形式呈现，便于查阅和记忆。
一、序数词的基本规则
英语中的序数词通常由基数词加“-th”构成，但有一些例外情况需要特别注意：
- 1st（first）
- 2nd（second）
- 3rd（third）
- 4th（fourth）
- 5th（fifth）
- 6th（sixth）
- 7th（seventh）
- 8th（eighth）
- 9th（ninth）
- 10th（tenth）
从11开始，大部分序数词以“-th”结尾，但11th是“eleventh”，12th是“twelfth”，13th是“thirteenth”。之后的数字则遵循常规规则，如14th（fourteenth）、15th（fifteenth）等。
