第六讲 数词
数词是用来表示事物的数目大小和顺序先后的词,也就是表示“多少”和“第几”的词。
表示数目的多少的词叫基数词。
基数词的构成。
数字 变化规律 基数词
1~12 没有变化规律,需特殊记忆 one、two、three、four、five、 six、seven、eight、nine、ten、eleven、twelve
13~19 这些词以teen结尾 thirteen、fourteen、fifteen、 sixteen、 seventeen、eighteen、nineteen
20~90 (其中整十的数字) 这些词以ty结尾 twenty、thirty、forty、fifty、 sixty、seventy、eighty、ninety
其他两位数 十位与个位之间用英文连字符“-” twenty-two、thirty-one
100~900 (其中整百的数字) 1~9的数字+ hundred one hundred、two hundred
其他三位数 1~9的数+ hundred+and+ 几十几 one hundred and ninety-nine、 one hundred and one、 three hundred and twenty-five
整千的数字 1~9的数字+ thousand one thousand、two thousand
注意:hundred、 thousand等前面有具体数字修饰时,后面不能加-s。表示约数时,词尾要加-s, 并与
of连用。如: hundreds of数以百计的。
单项选择。
( ) 1. There are ________ days in a year.
A. three hundreds and sixty-five B. three hundred and sixty five
C. three hundred and sixty-five D. three hundreds sixty-five
( ) 2. Danny lives in ________.
A. room 404 B. Room 404 C.404 room D. 404 Room
思路点拨:例题考查数词的构成形式和数词的用法。 1.在表示具体数字时,hundred等词尾不能加-s,且百位和十位之间要用连词and;个位和十位之间要加连字符,故本题选C。 2.表达编号时,基数词位于名词后,且名词首字母大写,故本题选 B。 答案1. C 2. B

二、单项选择。

1. 表示事物的先后顺序的词称为序数词。
2. 序数词的构成。
构成方法 示例
一般情况在基数词后加-th 构成相应的序数词 four—fourth, thirteen—thirteenth
整十数的序数词的构成是将基数词词尾的y变为ie,再加-th twenty—twentieth, forty—fortieth
两位及两位以上的基数词变为序数词时,仅将个位数变成序数词 twenty-one—twenty-first, one hundred and fifty-three—one hundred and fifty-third
特殊情况特殊记 one—first, two—second, three—third, five—fifth, eight—eighth, nine—ninth, twelve—twelfth
3. 序数词的用法。
(1) 序数词在使用时一般在前面加上定冠词the,但当序数词前有物主代词等修饰时,不再加定冠词。
如: The Yellow River is the second longest river in China. 黄河是中国的第二长河。
Today is her ninth birthday. 今天是她九岁的生日。
(2) 序数词前可以加上不定冠词a或an,用来表示“再一;又一”。如:
I can have a third try. 我可以再试一次。(表示这将是第三次尝试)
单项选择。
( ) 1. There are ________months in a year. March is ________ month of the year.
A. twelve;third B. twelfth;the third C. the twelve;third D. twelve;the third
( ) 2.—When is Women's Day
—It's on ________.
A. the 8 of March B.8 of March C. the 8th March D. March 8th
思路点拨:例题考查基数词和序数词的运用。 1.第一空问一年有多少个月,且months是名词复数,所以应填基数词,基数词前不用the。第二空表示第几个月,所以应填序数词,序数词前要用 the,故本题选 D。 2.“3月8日”应表示为: March 8th或 the 8th of March, 故本题选 D。 答案1. D 2. D
[过关训练2] 一、单项选择。
( ) 1. December is ________ and last month in a year.
A. the twelveth B. twelve C. the twelfth D. twelfth
( ) 2. Jenny was born ________.

A B C
( ) 2. I'm in Class first. ________
A B C
( ) 3. February is the two month of the year. ________

1. 表示编号。在表示有编号的事物时,可用基数词,也可用序数词,但表现形式不同。如:
Room 577/Room No. 577 第577号房间
the No. 16 Middle School 第十六中学
Book Four/the Fourth Book 第四册书
two nine zero two three two nine one 电话号码29023291
one three eight Zhongshan Road 中山路138号
注意:基数词变序数词的规则:一、二、三特殊记 (first、second、 third), th 从四起 (序数词尾都有th), 八去t, 九去 e (eighth, ninth), f来把ve替(fifth), ty变为tie ( 整 十 的数词),然后再加th (twentieth), 想要变为几十几,只变个位就可以。
2. 表示年、月、日。
(1) 表示“年”用基数词,通常先读前面两位数,再读后面两位数。如:
1949 读作 nineteen hundred and forty-nine 或 nineteen forty- nine
1902 读作 nineteen hundred and two 或 nineteen zero two
(2) 表示“月”, 用“介词in +某月”。如:
in July 在七月
(3) 表示“日期”,前面要用定冠词the,表示具体某日要用介词on。如:
on the twenty-fourth 在二十四日
(4) 表示“某年某月”用介词in,表示“某年某月某日”用介词on。如:
in August 2017 读作in August, twenty seventeen
on November 23, 1986 读作on November the twenty-third, nineteen eighty-six
3. 表示时刻。
(1) 表示整点, 用“钟点数 + o’clock”来表示 (o’clock常省略)。如:
five(o’clock)五点 (5:00)
(2) 表示半点, 用“钟点数 + thirty”或“half + past + 钟点数”表示。如:
six thirty/half past six 六点半(6:30)
(3) 表示几点几分,用“钟点数+分钟数”表示。半小时内,也可以用“分钟数+past+钟点数”表示。超过半小时,也可以用“60- 分钟数 + to + 下一个钟点数”表示。如:
eight seven/seven past eight 八点过七分 (8:07)
seven fifty/ten to eight 八点差十分 (7:50)
4. 表示数学运算。
Two plus three is five. 二加三等于五。
Ten minus six is four. 十减六等于四。
Three times four is/are twelve. 三乘以四等于十二。
Sixteen divided by four is four. 十六除以四等于四。
5. 表示分数。分子用基数词,分母用序数词。当分子大于 1 时,分母用复数。如:

1 / hours一个半小时(读作: one and a half hours)
2 / metres 二又四分之三米(读作: two and three-fourths metres)
