2015届数词复习课件

课件24张PPT。2015届高考语法复习系列数 词数词考点及复习要点
虽然数词并不是近几年的考查重点，但我们在复习时还是需要搞清楚以下几个概念：
1、数词的基本用法及比较；
2、数词的位置；
3、倍数词的表达习惯；
4 、数词作定语;
5 、在习惯用语中数词的用法；　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。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： 345　three hundred and forty-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scores of people 指许多人；b.　在一些表示"一排"或"一组"的词组里；
　 如：They arrived in twos and threes.　他们三三两两的到达了。
c. 表示"几十岁"；in his twenties
d. 表示"年代"，用 in +the +数词复数；in the 1980s
e. 在乘法运算的一种表示法里，如：
3 x 5 = 15 Three fives is (are) fifteen.
二、序数词
　　序数词的缩写形式： first---1st　second---2nd　
thirty-first---31st　 3—3rd
三.分数表示法
　　构成：基数词代表分子，序数词代表分母。分子大于1时，分子的基数词用单数，分母序数词用复数：1/3 one-third ； 3/5 three fifths.
