2→two; 3→three;
4→four; 5→five;
6→six; 7→seven;
8→eight; 9→nine;
10→ten; 11→eleven;
12→twelve
数字 形式 例词
13~19 以-teen结尾 13→thirteen; 14→fourteen;
15→fifteen; 16→sixteen;
17→seventeen; 18→eighteen; 19→nineteen
20~99 整十数 以-ty结尾 20→twenty; 30→thirty; 40→forty; 50→fifty;
60→sixty; 70→seventy; 80→eighty; 90→ninety
数字 形式 例词
20~99 非整 十数 在十位数与个位数之间要加连字符“-” 21→twenty-one; 28→twenty-eight;
96→ninety-six
100~999 整百数 由1~9对应的数词后面加“hundred (百)”构成 100→one hundred; 300→three hundred;
600→six hundred
数字 形式 例词
100~999 非整百数 百位数和十位数(若无十位数则和个位数)之间加“and”,十位数和个位数之间用连字符“-”连接 148→
one hundred and forty-eight;
406→
four hundred and six
拓展:较大数字的表达,如1,000→a thousand (千);
1,000,000→a million (百万);
1,000,000,000→a billion (十亿)。
如果表示不确定的数目时,
则可用hundreds of/thousands of/millions of/billions of。
2.序数词
序数词是表示先后顺序的词。常见的序数词如下:
序数词变化规则 例词
第一至第三 特殊变化 first→1st; second→2nd; third→3rd
第四至第十九 由相应的基数词(除五、八、九、十二之外)加-th构成 fourth→4th; fifth→5th; sixth→6th; seventh→7th;
eighth→8th; ninth→9th; tenth→10th; eleventh→11th;
序数词变化规则 例词
第四至第十九 由相应的基数词(除五、八、九、十二之外)加-th构成 twelfth→12th; thirteenth→13th; fourteenth→14th;
fifteenth→15th; sixteenth→16th; seventeenth→17th;
eighteenth→18th; nineteenth→19th
第二十至第九 十整十序数词 先将整十基数词词尾-ty 中的y变成ie,然后再加-th twentieth→20th; thirtieth→30th; fortieth→40th;
fiftieth→50th; sixtieth→60th; seventieth→70th;
eightieth→80th; ninetieth→90th
序数词变化规则 例词
第二十一至第 九十九非整十 序数词 将基数词的个位数变成序数词,十位数不变 twenty-first→21st; twenty-second→22nd;
twenty-third→23rd; twenty-fourth→24th;
fifty-first→51st; ninety-third→93rd
第一百及以上 序数词 将基数词的结尾部分变成序数词 one hundredth→100th;
four hundredth→400th;
eight hundredth→800th;
seven hundred and third→703rd
巧学妙记口诀
  基变序,有规律,末尾一般加-th。一、二、三特殊记,词尾字母t、d、d;八去t,九去e,ve要用f来替;逢十改y为ie,后跟-th莫忘记;若想表示第几十几,个位变序就可以。
