# 数词的用法

2.能够准确的利用语法点做题。

1. 数词有基序数和序数词两类。基数词表示数量的大小，如one, two, three, four等。 序数词表示顺序的词，如first, second, third, fourth等。

(1)第4至第19一般是在基数词后加th，但变化特殊的有

one—first, two—second, three—third, eight—eighth, nine—ninth, five—fifth, twelve—twelfth (2)逢十的twenty, thirty?ninety，变y为ieth。如twenty—twentieth, ninety—ninetieth (3)表示第几十几或第几百几十几，只需将个位数改为序数词。 如：56—fifty-six — fifty-sixth，

635 — six hundred and thirty-five — six hundred and thirty-fifth

(4)hundred, thousand, million 等序数词形式为 hundredth, thousandth, millionth 等。 3. 基数词的读写方法

(1)三位数的读写法：个位与十位之间用连字符“-”；百位与十位之间加and；十位为零时也要加and。如： 365读作three hundred and six-five

605读作six hundred and five

(2)大于三位数的读写法：从个位起每三位打一个撇号“，”，第一个撇号读thousand，第二个撇号读million，第三个撇号读billion, 各撇号之间的数按三位及三位以下的数的读法读。如： 一万10,000 读作 ten thousand 十万100,000读作 one hundred thousand 23, 589读作twenty-three thousand five hundred and eighty-nine
