【数词】 定义： 基数词是表示数目的词，用于描述数量的多少。例如 1、2、3、10、20 等，它们可以用来表示具体的数量，如一个苹果（one apple）、两个学生（two students）。 序数词是表示顺序的词，用于描述事物在顺序上的位置。比如第一（first）、第二（second）、第三（third）等，常用来表示日期、楼层、名次等的顺序，如五月一日（May 1st）、三楼（the third floor）、第一名（the first place）。 温馨提醒： 1. 基数词表示确切数字时，hundred，thousand，million，billion 等词不加“s”，如 two thousand students ；表示不确定数字时，加“s”并与“of”连用，如 hundreds of ，thousands of 。 - 例：There are two hundred people. - 例：Hundreds of people came. 2. 基数词表示“几十几”，十位和个位用连字符“-”连接，如 twenty-three ，fifty-nine 。 - 例：She is fifty-nine. 3. 序数词前一般加“the”，但前有形容词性物主代词或名词所有格时不加，如 my first book ，Tom's second bike 。 - 例：The first lesson is easy. - 例：This is her third time. 4. 分数分子用基数词，分母用序数词，分子大于 1 分母用复数，如 one third ，two fifths 。 - 例：One third of the students are boys. - 例：Two fifths of the land is covered. 练习题：单项选择50题(真题+模拟+日常练习) ( 7 )中考复习*语法专练 10 道与初中数词相关的中考真题： 1. （2024 黑龙江 中考真题）Two _____ dollars is enough to buy the bike, but A. hundreds B. hundreds C. hundred D. hundred 2. （2024 甘肃白银 中考真题）June is the _____ month of a year.
