序數(Ordinal Numbers)
序數(ordinal numbers)是一群代表順序的字,用「數字」(cardinal number)演變而來。
序數的用法通常是在前面加the。
Edison is the first. à Edison是第一名.
Gwendolyn is the second. à Gwendolyn是第二名.
Justin is the third. à Justine是第三名.
Daisy is the fourth. à Daisy是第四名.
Wrinkle is the fifth. à Wrinkle是第五名.
Ps. 因為一共五個人在比賽, Wrinkle得了第五名, 其實就是最後一名.
所以也可以說: Wrinkle is the last.
