数词1.什么叫做数词?表示数目多少或顺序多少的词叫数词,数词分为基数词和序数词。

5)百位数,由百位数+and+两位数组成。
注:1、1000以上几个的词,每三位数加一个逗号,第一个逗号前的数为thousand,第二个逗号前的数为million(百万), 第三个逗号前的数为billion(十亿),第四个逗号前的数为trillion(万亿)888,888,888,888eight hundred and eighty-eight billion, eight hundred and eighty-eight million, eight hundred and eighty-eight thousand, eight hundred and eighty-eight2、基数词常与名词构成的合成词在句中作定语,中间要用连字符“_”,这个名词只用单数形式.a two hundred –word reporta seven-day holidaya 3 –year –old girl3. 基数词的用法1、表示一个具体数字时,hundred, thousand,million,billion一律不用复数;在表示一个不确定数字时则用复数。

2)4-19都是在后面加上th,特殊的有fifth, eighth, ninth,twelfth。
3)20-90把y变成ie然后加th,如twentieth。
4)21-99的序数词变后面的个位数。
序数词可以用缩写,如1st, 2nd, 3rd ,4th…序数词的用法(1)序数词主要用作定语,前面要加定冠词,例如:The first truck is carrying a food baskets.John lives on the fifteenth floor.(2)序数词有时前面可加不定冠词来表示“再一”,“又一”这样的意思,例如:We'll have to do it a second time.Shall I ask him a third time?When I sat down,a fourthman rose to speak.(3)表示年,月,日时,年用基数词表示,日用序数词表示。
