扩展资料：
基数词 1-12 是独立单词,需逐个记忆。
基数词 13-19是个位数词的词干后加-teen 构成。其中 thirteen, fifteen, eighteen 变化不规则。
基数词 20-90 是在个位数词后面加 -ty 构成。其中 twenty, thirty, forty, fifty, eighty 变化不规则。
基数词 21-99 是在十位数词后面加上个位数词合成,中间加上连字符 " - " 。
例如: 21 twenty-one,95 ninety-five
基数词三位以上的数词, 在百位和十位之间,一般要用连词"and "，十万位和万位,亿位和千万位之间通常也要加and。例如: 132 one hundred and thirty-two,1340 one thousand three hundred and forty.
（2）英语中没有万，十万，千万，亿这样的单位数词，ten thousand 十千，十千（1000×10）=一万。故用阿拉伯数字书写千以上的数目时，要由右向左每三位数间留一个空格或写一个逗号。第一个前为thousand；第二个前为million；第三个前为thousand million（英）或billion（美）。每两个空格间或两个逗号间的三位数都被看作“十位数或百位数的千”或“十位数或百位数的百万”。例如56 000 fifty-six thousand和600,000,000 six hundred million。
（3）dozen,score,hundred,thousand,million等数词前面有基数词或某些表示数量的形容词时，不加-s。例如 a few hundred meters 几百米 several million people 数百万人 two thousand teachers 两千位老师，但如表示“几百”“几千”“几百万”等笼统的数目时，则应用-s of构成短语。如：hundreds of books 几百本书 thousands of workers 几千个工人
（4）hundred、 thousand、 million作数词时,不用复数,前面可以加上one, two, …等其它数词。用作名词时复数表示“成…上…”,后面必须要有of,前面可以加上some,many,several等词。如：five hundred(五百), hundreds of(成百上千的), ten thousand(一万), thousands of(成千上万的), millions of(成百万的).
