语法数词分为基数词和序数词两种
表示数目或数量多少的词叫基数词;表示数目顺序的词叫序数词
基数词的构成1) 1-20 表达英语中有相对应的单词,两位数的表达方法为整数加个位数组成,如 twenty-one; 三位数如 one hundred and twenty-one, 百位和十位之间加and,后面两位数要加连字符,四位以上只有在百位和十位之间加and,如 1134 one thousand, one hundred and thirty-four
英语中没有万,千万,亿等单位,如果需要表示万的话用thousand 计算, 例如 1,4283 fourteen thousand two hundred and eighty-three ;如果需要表示千万和亿的话用million 计算,如 2,1824,5200 two hundred and eighteen million two hundred and forty-five thousand and two hundred
2)用作基数词单位的hundred, thousand, million, billion 不带复数词尾 -s,但若用于表示数百、数千、数百万这样的泛指,则用复数
如:About two thousand people died in the earthquake
大约有两千人在地震中丧生
Thousands of people go to the seaside every year
每年成千上万的人到海滨去
Two _________(hundred) of students took part in the sports meeting last week
解析:正确答案为hundred
前面出现具体数字,后面只能用hundred,但是后面出现了 of, 很多学生会误写成hundre
