相信月份词汇我们都会选择正确且合适的，但是日期词需要如何表达呢？
没错，需要用到序数词 ！
【互动精讲】（一）基数词
1. 表示数量多少的词是基数词，如：one, two, three，four等。
2. 数词的构成
1）从1－12分别由从one到twelve，12个各不相同的词表示。
one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve
2）从13－19均以后缀-teen结尾。
thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
3）从20－90的整十数词均以后缀-ty结尾。表示“几十几”时，个位和十位之间需加连字符。
30，40，40，80的拼写较为特殊
twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety

twenty-three
4）整百数由1—9加hundred构成。
one (a) hundred five hundred
5) 整百数和整十数之间由and连接，十位与个位之间要加连字符“-”。如果十位数为零，那就在百位和个位
之间用and连接。
246 two hundred and forty- six
2、 序数词
序数词表示排列顺序，如first, second, third等。
1) 序数词第一、第二和第三为first, second和third,其他序数词的构成是在基数词后加th。例如：
six → sixth four → fourth
2) fifth(第五)、 eighth (第八)、 ninth (第九)和twelfth (第十二)在拼法上有变化。
first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, twelfth, thirteenth, fourteenth, fifteenth,
sixteenth, seventeenth, eighteenth, nineteenth
3) 二十、三十等基数词变为序数词时,要把y变成ie再加-th。例如：
twenty→twentieth forty→fortieth
twentieth, thirtieth, fortieth, fiftieth, sixtieth, seventieth, eightieth, ninetieth
4) 基数词几十几变成序数词时,表示几十的数词不变,只把表示几的基数词变成序数词。例如：
[来源:学|科|网]
twenty-one → twenty-first forty-five → forty-fifth
5）.序数词的缩略形式是由阿拉伯数字加序数词的最后两个字母构成。例如：
1st, 2nd, 3rd, 4th, 21st, 32nd, 40th
7) 序数词前必须加定冠词theThe first time I came to Nanjing, I liked it very much.
我第一次来南京，我就非常喜欢这个城市。
