 在进行了短暂热身练习之后，教师有意识地将书中

基数词最基本的构成

其他的基数词可以以下的方式构成

1)  21---99 先说“几十”， 再说“几” 中间加连字号：

e.g.:       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）

    e.g.:       223----two 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“，”，第一个“，”号前为thousand, 第二个“，”号前为million, 第三个“，”号前为billion,（美式）或thousand million(英式)，然后一节一节表式

e.g.:   1,001---one thousand and one

   9,743—nine thousand, seven hundred and forty-three

   750,000,000---seven hundred and fifty million

4）序数词一般以与之相应的基数词加词尾th构成， 有特别的地方：

A: one-first    two—second  three-third  five—fifth                                          eight-eighth                            nine-ninth

 twelve-twelfth

B: 以-ty结尾的词，要先变y为I，再加-eth

e.g.: twenty—twentieth  forty—fortieth

C: 以one, two, three, five, eight, nine 收尾的多位数词要照第一条变

e.g.: twenty—twenty-first  ninety-nine—ninety-ninth

D: 序数词主要用作定语，前面一般要加定冠词（或物主代词）

 5) 分数词：是以基数词和序数词合成的，基数词代表分子序数词代表分母，除了分子是“1”的情况外，序数词都要用复数 。
