1st. 2nd. 3rd,后面不会了,帮忙给看看,后面怎么写啊,一直到21答:(1)数字1-3是1st, 2nd, 3rd (2)4-20都是数字后面加-th,例如:4th, 5th, 11th, 12th (3)21-99,凡是带1的数字后面加st,带2的数字后加nd,带3的后面加rd,其他的加th。例如:21st,31st,41st,...;22nd,32nd,42nd,...;23rd,33rd,43rd,...;24th,25th,35th,...。
盲填中序数词缩写对吗答:如:1st, 2nd, 3rd, 4th, 5th, 6th, 7th, ...41st, 52nd, 63rd, 74th。方法:你看数字的尾数,如果尾数是1.2.3这三个数,1后面跟st(first的缩写),2后面跟nd(second的缩写),3后面跟rd(third的缩写)。第21,22,23,31,32,33...等应该写成如21st,22nd,23rd,31st,32nd,33rd ...
