1、基数词1至12是独立单词，13至19均以“teen”结尾，“几十”的整十数均以“ty”结尾；序数词由基数词变成，一般在基数词后加“th”，牢记下面口诀：基变序、有规律，词尾加上“th”；一、二、三特殊记，词尾字母t或d；八减t、九去e、f来把ve替；单词ty作结尾，ty先改tie；若是碰到几十几，只变个位就可以。
2、基数词的用法：①表准确数目时，hundred, thousand , million都不用复数，如：two thousand ；表示不准确数目时，hundred , thousand , million的复数形式与of连用，如：hundreds of workers(数百工人) ②基数词用来表年代，如：2002年，twenty o two 或者说 two thousand and two ③表时间，如：9:00 nine o’clock 10:15 a quarter past ten ④编号，简单的编号可用基数词或者序数词表示，复杂的编号多作基数词表示，如：第一课 Lesson One 或 the First Lesson 第147面 page 147 读作page one four seven 或page one hundred and forty-seven ⑤表温度及比赛比分等，如：The temperature will be 2-9 . （读作two to nine ） 2:1 读作two to one
3、序数词前常用定冠词“the”，但以下三种情况不用the，①序数词前有物主代词或名词的所有格时，序数词前不用the ，如：Lily’s second pen 。②序数词的意义为“another”时，序数词前不用the,常用a / an ，如：You’d better try a second time . 你最好再试一次。 ③谈论考试、比赛获得的名次时，序数词前常不用the，如：Who was second in the high jump? 跳高谁第二名？
4、基数词与序数词的合用：①表示年份、日期时，年份用基数词，日期用序数词，如：1997年读作 nineteen ninety-seven , 9月10日 September 10th , 读作 September (the) tenth 或 the tenth of September , 1998年10月8日可写为 October 8(th) , 1998 ( October the eighth , nineteen ninety-eight ) 或 8(th) October 1998 (the eighth of October , nineteen ninety-eight ). ② 表分数时，分子用基数词，分母用序数词。当分子大于1时，分母的序数词后加s 。如：1/2 读a half / one half , 2/3 读作 two thirds
5、单项选择练习：
1. He lives in ______ . A. the Room 203 B. Room 203 C. 203rd Room D. 203 Room
2. There were _______ people in the park last Sunday. A. thousands B. thousand of C. thousand D. thousands of
