数词
1.基数词用于表示数目。基数词中最基本的是下面这些,所有其他数词都可以由这些词构成:其他的基数词可以以下面的方式构成:
(1)22——99先说“几十”,再说“几”,中间加连字号:
23 twenty-three 89 eighty-nine
(2)101——999先说“几百”,再加and,再加末两位数(或末位数):
216 two hundred and sixteen
423 Four hundred and twenty-three
809 eight hundred and nine
(3)1,000以上的数,先从后向前数,每三位数加一个“,”,第一个“,”号前为thousand,第二个“,”号前为million,第三个“,”号前为billion,然后一节一节表示:
1,001 one thousand and one
4,000 four thousand
9,743 nine thousand,seven hundred and forty-three
174,301 a(one)hundred and seventy-four thousand,three hundred and one
750,000,000 seven hundred and fifty million 4,000,000,000 four billion
2.序数词用于表示顺序。序数词一般以与之相应的基数词加词尾th构成,如seventh(第七),tenth(第十)。但下面这些基数词在变为序数词时,有特别的地方:
(1)one—first;two—second;three—third;five—fifth;eight—eighth;nine—ninth;twelve—twelfth.
(2)以-ty结尾的词,要先变y为i,再加-eth,例如:

(3)以one,two,three,five,eight,nine收尾的多位数词,要照第一条办法变,例如:
twenty-one—twenty-first;twenty-two—twenty-second thirty-five—thirty-fifth;ninety-nine—ninety-ninth
