6、 （ 21 twenty-one； 76 seventy-six）4. 两位数（整数），以ty结尾； （40 forty； 90 ninety）4. 三位数，在百位数和十位数之间用and连接。 101 a hundred and one； 320 three hundred and twenty； 648 six hundred and forty-eight5. 百（hundred），千（thousand），百万（million），千万（billion）6. 表示确切的百、千、百万时，不能用其复数形式； ( 400 four hundred，hundred不加s) 表示成百、成千时，用其复数

7、形式；( 成百 hundreds of; 成千 thousands of )7. 表示“人的不确切岁数”，用几十的复数形式； He became a professor in his thirties. （他在三十多岁成为教授。）8. 表示年代时，用几十的复数形式； It was in 1960s. （那是在20世纪60年代。）二、序数词1、英语的序数词基本变法：(1) 1-19：一般在基数词后加th 特殊情况：one-first ; two-second; three-third; eight-eighth; nine-ninth; -ve结尾的改ve为f加th；（如five-fifth；

8、twelve-twelfth） (2)两位数（整数），改y为-ie，加th； (如twenty-twentieth； thirty-thirtieth)（3）两位数/多位数（非整数），仅个位数部分用序数词。 （如：thirty-sixth, fifty-third, one hundred and twenty-first）2.缩写形式：阿拉伯数字 + 序数词末尾两个字母 （只有1st, 2nd, 3rd为特殊形式，其他都是阿拉伯数字+ th） first -1st； second-2nd; twentieth -20th; twenty-third -23rd3、基数词/序数词用法辨别1.

9、基数词也可以表示顺序，要将基数词放在名词之后。 the first Lesson - Lesson One / the fifth page - Page 52. (1)序数词前面加the时,表示顺序,This is the fourth time I come here. 这是我第四次来这儿。 (2) 加a/an时表示“再一、又一”Weve tried it three times. Must we try it a fourth time? 我们已经试过三遍了，还必须再试一次（第四次）吗？三、时间的数词表示法1. 表示时刻（1）整点用“ oclock ”； （5: 00读作five ocl

10、ock或five） （2）几点过几分，分钟 + past + 小时； （five past seven 七点过五分； a quarter past eight八点过一刻； half past eight八点半）（3） 几点差几分，分钟 + to + 小时； （ten to eight八点差十分； a quarter to twelve 十二点差一刻）（4） 直接法：小时 + 分钟； （6: 31读作six thirty-one； 10:26 ten twenty-six）2. 表示日期，用the 加序数词表示，或用缩写形式 12月1日: Dec.1st或the first of Decembe

12、”时，序数词用单数；除此之外，序数词用复数 1/3：one third / a third； 1/2：a half； 1/4：one quarter ； 3/4：three fourths/ three quarters ； 1：one and a half2. “半”的表达： 一半-a half； 半小时half an hour； 1.5小时one and a half hours或one hour and a half. 3. 当分数后接名词时，如果分数值大于1，名词用复数；小于1，名词用单数。 one and a half hours一个半小时； two and three fourth
