拓展
one (1) two (2) three (3) four (4) five (5) six (6) seven (7) eight (8)nine (9) ten (10) eleven (11) twelve (12)
(1) 1～12的基数词。
twenty (20) thirty (30) forty (40) fifty (50)
sixty (60) seventy (70) eighty (80) ninety (90)
(2) 13～19 的基数词，其规律是在 3～9 (经适当变形后)的基数词后面加 teen。
thirteen (13) fourteen (14) fifteen (15) sixteen (16) seventeen (17) eighteen (18) nineteen (19)
(3) 整十的基数词，其词尾都是ty。
twenty -one (21) thirty- two (32)
forty -five (45) fifty- six (56)
(4) 两位数的非整十基数词：整十数加个位数，中间用连字符 “ - ”连接。
基数词不难记，找清规律很容易。
十二以内词各异；
十三数到十九去，后加 teen 莫忘记。
二十、三十……至九十，整十之后有 ty ；
要说“几十几”，中间“-”号别丢弃；
hundred 是“一百”，请你记住莫大意。
