表示数量多少的数词叫做基数词，如one,
two,
three等。
(二)基数词
基数词的拼写
1
(1)
one—twelve,
无规律可言，应逐一记忆。
(2)
thirteen—nineteen,
表示“十几”，在个位数后
加后缀 teen，读作/ti n/，但要注意下面几个词
的拼写：thirteen(13),
fifteen(15),
eighteen(18)。
(3)twenty到ninety,
表示“几十”，以 ty结尾，但需注意下面几个词的拼写：twenty(20)，thirty(30)，
forty(40)，fifty(50)，eighty(80)。
(4)“几十几”的表达方法：用整十数加个位数表示，
中间用连字符“ ”把整十数和个位数连接起来。
如：twenty five(25)，sixty- eight(68)。
(5)一百的表示方法为one
hundred或a
hundred。
要表示“几百”，用具体数字加上hundred,
如five
hundred(500)，注意此时的hundred是单数形式。表示“几百几”时，要在百位数和十位数(或个位数)之间加and。如：one
hundred
and
two(102)。
