中考数词讲解

数词讲解一.数词分为基数词和序数词两种,基数词表数目,序数词表顺序。
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(thousand)‖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.8.hundred,thousand,million用复数形式修饰名词时要用―of+复数名词‖,如:数以百计的年轻人hundreds of young people;数以千计的书thousands of books.注意:hundreds of/thousands of/millions of +复数名词,其前面不能加具体的数词,但可加several或many.Hundreds of new buildings have sprung up here this year.Thousands upon thousands of people in South Africa are rising against their oppressors.Thousands and thousands of people come to visit the city every day.(二)序数词——由基数词转变而来,表示―这是第N个‖1.口诀巧记基数词变序数词:―一、二、三,特殊记,八去‖t―,九去‖e―,‖ve―要用‖f―替,见‖y―变成‖i―和‖e―,词尾加上‖th―,若是遇到几十几,只变个位就可以。
