一至三十一的序数词分别用英语怎么写(不要缩略)?

1、序数词有缩写形式,也要记住: first(第一)缩写为1st, second (第二)缩写为2nd, third(第三)缩写为 3rd,其他数序词是以-th结尾的,如: fourth(第四) 缩写为4th。 第二十至第九十九的序数词: 20 – 90整十位数序数词 – 将对应的基数词词尾中的y变为i,然后加eth构成。

2、~30的序数词的缩写如下:1st , 2nd , 3rd , 4th , 5th , 6th, 7th , 8th ,9th ,10th;11th,12th,13th,14th,15th,16th,17th,18th,19th,20th;21st , 22nd , 23rd , 24th , 25th , 26th, 27th , 28th ,29th ,30th。

3、英语上数词分为两大类:基数词和序数词。序数词:是指表示顺序的数词。其主要形式:(1)从第一至第十九 其中,one— first, two— second, three— third, five— fifth,eight—eighth,nine—ninth,twelve— twelfth为特殊形式,其它的序数词都是由其相对应的基数词后面添加“th”构成。

4、至99序数词如下:1至10序数词 第1,first,1st;第2,second,2nd;第3,third,3rd;第4,fourth,4th;第5,fifth,5th;第6,sixth,6th;第7,seventh,7th;第8,eighth,8th;第9,ninth,9th;第10,tenth,10th。

5、在英语中,序数词用于表示顺序或次序。从第一至第三十一位,这些序数词的构成规律较为明显。例如,从第一到第十,它们依次是first,second,third,fourth,fifth,sixth,seventh,eighth,ninth和tenth。

6、到30的序数词为:1st = first 2nd = second 3rd=third 4th=fourth。5th=fifth 6th=sixth 7th=seventh 8th=eighth。9th=ninth 10th=tenth 11th=eleventh 12th=twelfth。13th=thirteenth 14th=fourteenth 15th=fifteenth 16th=sixteenth。17th=seventeenth 18th=eighteenth 19th=nineteenth 20th=twentieth。
