英语基数词与序数词专讲
英语中的数词包括基数词和序数词两大类,它们的用法非常复杂,为了便于同学们系统地复习数词,现就小学阶段数词的主要内容作以下归纳。
一、基本构成(一)基数词——从1数到n1.1—12的基数词是独立的单词,即:one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve。
2.13—19的基数词以-teen结尾。
如:fourteen,seventeen等,但13,15,18较特殊,13—thirteen 15—fifteen 18—eighteen。
3.20—90的整十位均以-ty结尾。
如:sixty,ninety,但20,30,40,50,80较特殊,20—twenty,30—thirty,40—forty ,50—fifty ,80—eighty。
4.十位数与个位数之间要加连字符号“-”,如:28—twenty-eight,96—ninety-six。
5.百位和十位(若无十位则和个位)之间加and,如:148—one hundred and forty-eight ,406—four hundred and six。
6.hundred(百),thousand(千),million(百万),billion(十亿)等前面即使有具体的数词,也不能在它们的后面加s。
如:600—six hundred,8百万—eight million。
7.1000以上的数字,从后往前数每三位加一个逗号“,”第一个逗号前为千(thousand),第二个逗号前为百万(million),第三个逗号前为billion(十亿)。
英语中无“万”这个词,我们可以用“几十个千(thousand)”表示几万,“几百个千(th ousand)”表示“几十万”。
如:2,510=two thousand five hundred and ten;84,296=eighty-four thousand two hundred and ninety-six;274,350=two hundred and seventy-four thousand three hundred and fifty。
