表示数目多少的数词叫基数词;表示顺序的数词叫序数词。
一、基数词1)基数词写法和读法:345threehundredandforty-five;2)基数词一般是单数形式,但下列情况,常用复数:a.与of短语连用,表示概数,不能与具体数目连用,如scoresofpeople指许多人;b.在一些表示”一排”或”一组”的词组里;如:Theyarrivedintwosandthrees.他们三三两两的到达了。
c.表示”几十岁”;d.表示”年代”,用in+the+数词复数;e.在乘法运算的一种表示法里,如:3x5=15Threefivesis(are)fifteen.二、序数词序数词的缩写形式:first---1stsecond---2ndthirty-first---31st三、数词的用法1)倍数表示法a.主语+谓语+倍数(或分数)+as+adj.+asIhavethreetimesasmanyasyou.我有你三倍那么多。
