这一期的英文课堂,Stacey老师将和同学们一起来复习数词的有关内容,
包括基数词、序数词、倍数等知识。大家认真学习哦! 首先,我们来看看数词的基础知识都有哪些内容吧:
【定义】英语中数词主要分为基数词和序数词两类。所谓基数,在数学上的理解是可以比较大小的数字。英语中的基数词(cardinal number)是用于描述事物数量的多少。
【形式】1.从1至10 one,two,three,four,five,six,seven,eight,nine,ten.
2.从 11至19 eleven,twelve, thirteen, fourteen, fifteen, sixteen, seventeen,eighteen, nineteen.
【注意】这里除 eleven, twelve, thirteen, fifteen, eighteen为特殊形式外,fourteen,sixteen,seventeen,nineteen都是由其个位数形式后添加后缀-teen构成。
3.从 20至99 整数几十中除twenty,thirty, forty,fifty,eighty为特殊形式外,sixty,seventy,ninety都是其个位数形式后添加后缀-ty构成。表示几十几时,在几十和个位基数词形式之间添加连字符“-”
如:21 twenty-one 77 seventy-seven
4.百位数个数基数词形式加“hundred”,表示几百,在几十几与百位间加上and.
如:101 one hundred and one 320 three hundred and twenty
5.千位数以上 从数字的右端向左端数起,每三位数加一个逗号“,”。从右开始,第一个“,”前的数字后添加 thousand,第二个“,”前面的数字后添加 million,第三个“,”前的数字后添加 billion。然后一节一节分别表示,两个逗号之间最大的数为百位数形式。
2,648 two thousand six hundred and forty-eight
16,250,064 sixteen million two hundred and fifty thousand and sixty-four
6.基数词在表示确切的数字时,不能使用百、千、百万、十亿的复数形式;但是,当基数词表示不确切数字,如成百、成千上万,三三两两时,基数词则以复数形式出现。
如:There are hundreds of people in the hall
