考点09 数词
备战2025年中考英语新课标(核心素养)一轮复习重难点冲冲冲
数词
表示数目多少或顺序多少的词叫数词,数词分为基数词和序数词。表示数目多少的数词叫基数词;表示顺序的数词叫序数词。数词有:一、二、三、四 、五、六、七、八、九、十、十一、十九、二十、百、千、万、百万、千万、亿、兆等。
基数词
数词
1)基数词写法和读法:345 three hundred and forty-five;
2)基数词一般是单数形式,但下列情况,常用复数:
a. 与of 短语连用,表示概数,不能与具体数目连 用,如scores of people 指许多人;
b. 在一些表示"一排"或"一组"的词组里;
如:They arrived in twos and threes. 他们三三两两的到达了。
c. 表示"几十岁":dozens of ages;
d. 表示"年代",用 in the 数词复数;
e. 在乘法运算的一种表示法里,如:3 x 5 = 15 Three fives is (are) fifteen.
部分基数词
1 one, 2 two, 3 three, 4 four, 5 five, 6 six, 7 seven, 8 eight, 9 nine, 10 ten,
11 eleven, 12 twelve, 13 thirteen, 14 fourteen, 15 fifteen,16 sixteen, 17 seventeen, 18 eighteen,
19 nineteen, 20 twenty, 30 thirty, 40 forty, 50 fifty, 60 sixty, 70 seventy,80 eighty, 90 ninety,
100 a hundred, 1,000 a thousand, 1,000,000 a million, 1,000,000,000 a billion.
基数词 1-12 是独立单词,需逐个记忆。
基数词13-19是个位数词的词干后加-teen 构成。其中 thirteen, fifteen, eighteen, 变化不规则。
基数词 20-90 是在十位数词后面加 -ty 构成。
基数词 21-99 是在十位数词后面加上个位数词合成,中间加上连字符 " ━ " 。
例如: 21 twenty ━ one 95 ninety ━ five
基数词三位以上的数词, 在百位和十位之间,一般要用连词"and "。
例如: 132 one hundred and thirty ━ two. 1340 one thousand three hundred and forty . 表示"万"的词英语中没有.如1万可用10千来表示。
ten thousand. 30万可用 three hundred thousand 来表示。
基数词注意事项
①十位数于个位数之间通常用连字符号“-”,一百以上的数词通常在百位与十位之间加and,没有十位数时百位数与个位数之间通常也要加and,
231 two hundred and thirty-one,509 five hundred and nine,1
465 a/one thousand,four hundred and sixty-five
②用阿拉伯数字书写千以上的数目时,要由右向左每三位数间由一个空格。第一个空格前为thousand;第二个空格前为million;第三个空格前为thousand million(英)或billion(美)。英语中没有万,十万,千万,亿这样的单位数词,故每两个空格间的三位数都被看作“十位数或百位数的千”或“十位数或百位数的百万”。
56 000 fifty-six thousand 600 000 000 six hundred million
③dozen,score,hundred,thousand,million等数词前面有基数词或某些表示数量的形容词时,不加-s。
a few hundred meters 几百米 several million people 数百万人 two thousand teachers 两千位老师,
但如表示“几百”“几千”“几百万”等笼统的数目时,则应用-s of构成短语。
hundreds of books 几百本书 thousands of workers 几千个工人
④表示一百,一千,一百万时需加上one或不定代词a。如:1000 a thousand 1031 a thousand and thirty-one 1100 one thousand ,one hundred 1498 one thousand,four hundred and ninety-eight 比较数字的开头多用不定代词a(见前两例),但在一个有百位数的数目前或在一个数目中间,则要用one(见后两例)。
基数词的位置
①位于another,all之后,
Can you have another two cakes? 你还能吃2块蛋糕吗?
The boy lost all the five pencils last week.这孩子上周把5枝铅笔全丢了。
②位于such和more之前,
I can finish reading two such books in two days.两天里我能读完这样的两本书。
Please give me one more apple to eat.请再给我一个苹果吃。
③可置于last,next,other之前或之后,
His last two books are written in English.他的后两本书是用英语写的。
巧记基数词
基数词不难记,找清规律很容易,十二以内词名异;
十三数到十九数去,后加-teen莫忘记。
二十 三十至九十,整十之后有-ty;
要说“几十几”,中间“-”号别丢弃,
hundred是“一百”,请你记住莫大意。
序数词
序数词的缩写形式:first---1st second---2nd thirty-first---31st
1. first (1st) 2. second (2nd) 3. third (3rd) 4.fourth (4th) 5.fifth (5th)

90.ninety ninetieth (90th) 100.a/one hundred one-hundredth (100th)
101. one hundred and one one hundred and first (101st)
1000. a/one thousand one thousandth (1000th)
1,000,000.a/one million one millionth (1,000,000th)
除了first, second, third以及和它们一起组成的高位序数词以外,序数词的构成方法是在 相应的基数词之后加-th,但要注意fifth, eighth, twelfth等不规则拼法。twenty, thirty等在变 为序数词时,要把y变成i, 再加-eth。
用法
一、整数的表示方法
1.表示二十以上的十位数,要在个位数与十位数之间加连字符号。表示百位数,要在百位数与十位数之间(无十位数,则在百位数和个位数之间)加and。在美国英语中,and往往省去。
68 ─ sixty-eight 156 ─ one/a hundred (and) fifty-six 602 ─ six hundred (and) two
2. 书写千位数以上的阿拉伯数字,从后往前每隔三位用一分节号,
1,000 = one/a thousand 10,000 = ten thousand 100,000 = one/a hundred thousand 1,000,000 = one/a million
在一些科技文章中,千位以上的数不使用分节号,而用一个空白字符表示分节,如:56 112 482。
3. hundred, thousand, million等词前面有具体数字或several修饰时,不加-s。
The magazine has two million readers.
不与数词或several连用,可以复数形式出现,表示“数以百计”、“成千上万”等。
Mr. Smith has donated (捐赠) hundreds of books to the school. (数以百计)
二、倍数的表达方法
1.用…times表示。My room is three times as large as yours. 我的房间是你的三倍大小。

This coat cost me as much again as the coat I have just bought.
这件外套和我刚买的那件外套的价格一样
三、分数、小数和百分数表示法
1.分数的分子以基数词表示,分母以序数词表示,当分子大于1时,序数词要用复数,其写法与读法如下:
1/2 — a/one half 1/3 — a/one third 1/4 — a/one fourth; a/one quarter 2/5 — two fifths
2. 小数是以基数词加小数点表示,小数点前面的数按基数词的规则读,小数点后面的数按个位基数词依次读出,
0.5 — zero point five 0.006 — zero point zero zero six 0.257 — zero point two five seven
148.06 — a/one hundred and forty-eight point zero six 其中zero可替换为naught或读作oh。

五、年份的表示法
1.年份通常用阿拉伯数字表示,用基数词读。公元前用B.C.表示,公元用A.D.表示,读 其字母音。A.D. 一般用于公元1年到公元999年之间的年份。
公元前502年写作502 B.C. 公元429年写作429 A.D. 公元1000年写作1000。
2.年代表示法 年代用年份的阿拉伯数字加-’s或-s表示。

365读作three hundred and six-five 605读作six hundred and five
(2) 大于三位数的读写法:从个位起每三位打一个撇号“’”,第一个撇号读thousand,第二个撇号读million,各撇号之间的数按三位及三位以下的数的读法读。
23, 589读作twenty-three thousand five hundred and eighty-nine
6, 632, 900读作six million six hundred and thirty-two thousand nine hundred
28, 000, 000读作twenty-eight million

考点09 数词
备战2025年中考英语新课标(核心素养)一轮复习重难点冲冲冲
数词
表示数目多少或顺序多少的词叫数词,数词分为基数词和序数词。表示数目多少的数词叫基数词;表示顺序的数词叫序数词。数词有:一、二、三、四 、五、六、七、八、九、十、十一、十九、二十、百、千、万、百万、千万、亿、兆等。
基数词
数词
1)基数词写法和读法:345 three hundred and forty-five;
2)基数词一般是单数形式,但下列情况,常用复数:
a. 与of 短语连用,表示概数,不能与具体数目连 用,如scores of people 指许多人;
b. 在一些表示"一排"或"一组"的词组里;
如:They arrived in twos and threes. 他们三三两两的到达了。
c. 表示"几十岁":dozens of ages;
d. 表示"年代",用 in the 数词复数;
e. 在乘法运算的一种表示法里,如:3 x 5 = 15 Three fives is (are) fifteen.
部分基数词
1 one, 2 two, 3 three, 4 four, 5 five, 6 six, 7 seven, 8 eight, 9 nine, 10 ten,
11 eleven, 12 twelve, 13 thirteen, 14 fourteen, 15 fifteen,16 sixteen, 17 seventeen, 18 eighteen,
19 nineteen, 20 twenty, 30 thirty, 40 forty, 50 fifty, 60 sixty, 70 seventy,80 eighty, 90 ninety,
100 a hundred, 1,000 a thousand, 1,000,000 a million, 1,000,000,000 a billion.
基数词 1-12 是独立单词,需逐个记忆。
基数词13-19是个位数词的词干后加-teen 构成。其中 thirteen, fifteen, eighteen, 变化不规则。
基数词 20-90 是在十位数词后面加 -ty 构成。
基数词 21-99 是在十位数词后面加上个位数词合成,中间加上连字符 " ━ " 。
例如: 21 twenty ━ one 95 ninety ━ five
基数词三位以上的数词, 在百位和十位之间,一般要用连词"and "。
例如: 132 one hundred and thirty ━ two. 1340 one thousand three hundred and forty . 表示"万"的词英语中没有.如1万可用10千来表示。
ten thousand. 30万可用 three hundred thousand 来表示。
基数词注意事项
①十位数于个位数之间通常用连字符号“-”,一百以上的数词通常在百位与十位之间加and,没有十位数时百位数与个位数之间通常也要加and,
231 two hundred and thirty-one,509 five hundred and nine,1
465 a/one thousand,four hundred and sixty-five
②用阿拉伯数字书写千以上的数目时,要由右向左每三位数间由一个空格。第一个空格前为thousand;第二个空格前为million;第三个空格前为thousand million(英)或billion(美)。英语中没有万,十万,千万,亿这样的单位数词,故每两个空格间的三位数都被看作“十位数或百位数的千”或“十位数或百位数的百万”。
56 000 fifty-six thousand 600 000 000 six hundred million
③dozen,score,hundred,thousand,million等数词前面有基数词或某些表示数量的形容词时,不加-s。
a few hundred meters 几百米 several million people 数百万人 two thousand teachers 两千位老师,
但如表示“几百”“几千”“几百万”等笼统的数目时,则应用-s of构成短语。
hundreds of books 几百本书 thousands of workers 几千个工人
④表示一百,一千,一百万时需加上one或不定代词a。如:1000 a thousand 1031 a thousand and thirty-one 1100 one thousand ,one hundred 1498 one thousand,four hundred and ninety-eight 比较数字的开头多用不定代词a(见前两例),但在一个有百位数的数目前或在一个数目中间,则要用one(见后两例)。
基数词的位置
①位于another,all之后,
Can you have another two cakes? 你还能吃2块蛋糕吗?
The boy lost all the five pencils last week.这孩子上周把5枝铅笔全丢了。
②位于such和more之前,
I can finish reading two such books in two days.两天里我能读完这样的两本书。
Please give me one more apple to eat.请再给我一个苹果吃。
③可置于last,next,other之前或之后,
His last two books are written in English.他的后两本书是用英语写的。
巧记基数词
基数词不难记,找清规律很容易,十二以内词名异;
十三数到十九数去,后加-teen莫忘记。
二十 三十至九十,整十之后有-ty;
要说“几十几”,中间“-”号别丢弃,
hundred是“一百”,请你记住莫大意。
序数词
序数词的缩写形式:first---1st second---2nd thirty-first---31st
1. first (1st) 2. second (2nd) 3. third (3rd) 4.fourth (4th) 5.fifth (5th)
6.sixth (6th) 7. seventh (7th) 8. eighth (8th) 9. ninth (9th) 10. tenth (10th) 11. eleventh (11th) 12. twelfth (12th) 13. thirteenth (13th) 14. fourteenth (14th) 15.fifteen fifteenth (15th) 16.sixteen sixteenth (16th) 17.seventeen seventeenth (17th) 18.eighteen eighteenth (18th) 19.nineteen nineteenth (19th) 20.twenty twentieth (20th) 21.twenty-one twenty-fist (21st) 22.twenty-two twenty-second (22nd)
30. thirty thirtieth(30th) 40.forty fortieth (40th) 50.fifty fiftieth (50th)
60. sixty sixtieth (60th) 70.seventy seventieth (7th) 80.eighty eightieth (80th)
90.ninety ninetieth (90th) 100.a/one hundred one-hundredth (100th)
101. one hundred and one one hundred and first (101st)
1000. a/one thousand one thousandth (1000th)
1,000,000.a/one million one millionth (1,000,000th)
除了first, second, third以及和它们一起组成的高位序数词以外,序数词的构成方法是在 相应的基数词之后加-th,但要注意fifth, eighth, twelfth等不规则拼法。twenty, thirty等在变 为序数词时,要把y变成i, 再加-eth。
用法
一、整数的表示方法
1.表示二十以上的十位数,要在个位数与十位数之间加连字符号。表示百位数,要在百位数与十位数之间(无十位数,则在百位数和个位数之间)加and。在美国英语中,and往往省去。
68 ─ sixty-eight 156 ─ one/a hundred (and) fifty-six 602 ─ six hundred (and) two
2. 书写千位数以上的阿拉伯数字,从后往前每隔三位用一分节号,
1,000 = one/a thousand 10,000 = ten thousand 100,000 = one/a hundred thousand 1,000,000 = one/a million
在一些科技文章中,千位以上的数不使用分节号,而用一个空白字符表示分节,如:56 112 482。
3. hundred, thousand, million等词前面有具体数字或several修饰时,不加-s。
The magazine has two million readers.
不与数词或several连用,可以复数形式出现,表示“数以百计”、“成千上万”等。
Mr. Smith has donated (捐赠) hundreds of books to the school. (数以百计)
二、倍数的表达方法
1.用…times表示。My room is three times as large as yours. 我的房间是你的三倍大小。

三、分数、小数和百分数表示法
1.分数的分子以基数词表示,分母以序数词表示,当分子大于1时,序数词要用复数,其写法与读法如下:
1/2 — a/one half 1/3 — a/one third 1/4 — a/one fourth; a/one quarter 2/5 — two fifths
2. 小数是以基数词加小数点表示,小数点前面的数按基数词的规则读,小数点后面的数按个位基数词依次读出,
0.5 — zero point five 0.006 — zero point zero zero six 0.257 — zero point two five seven
148.06 — a/one hundred and forty-eight point zero six 其中zero可替换为naught或读作oh。
3.百分数是由基数词或小数加百分号组成,百分号(%)读作per cent,
0.6% — zero point six per cent 5% — five per cent 100% — one hundred per cent 12.34% — twelve point three four per cent
四、时间的表示法

使用十二小时计时制,为了避免午前、午后时刻的混淆,有时要在时刻后面加a.m. /am 或p.m. /pm以示区别。如:10:11 a.m.、 6:20 p.m.。
2.二十四小时计时制
用于军事或国际时刻的二十四小时制,书写时用四位数字。“时”和“分”之间可用“:”, 也可省略。如:0000(零时)、1300(十三时)、18:30(十八时三十分)。 年、月、日的表示法
五、年份的表示法
1.年份通常用阿拉伯数字表示,用基数词读。公元前用B.C.表示,公元用A.D.表示,读 其字母音。A.D. 一般用于公元1年到公元999年之间的年份。
公元前502年写作502 B.C. 公元429年写作429 A.D. 公元1000年写作1000。
2.年代表示法 年代用年份的阿拉伯数字加-’s或-s表示。
十七世纪二十年代写作1620’s或1620s。 初期、中期、末期分别用early,mid-和late表示。三十年代初期写作the early thirties。 三十年代中期写作the mid-thirties。
三十年代末期写作the late thirties。 二十世纪五十年代初期写作the early 1950’s;
中期写作the mid-1950’s; 末期写作the late 1950’s。
3.月、日的表示法 表示月、日既可以先写“月”再写“日”,也可先写“日”再写“月”。

表示年、月、日,要将年份放在最后,用逗号和月、日隔开,
1998年7月1日写作 July 1, 1998或1 July, 1998。
在非正式文体中,年、月、日可以全用数字表示。
1996年6月10日写作6,10,1996或10,6,1996。为避免误解,宜将月份拼出。

英语数词学习要点
1. 数词的种类
数词有基序数和序数词两类。基数词表示数量的大小,如one, two, three, four等。序数词表示序数,如first, second, third, fourth等。数词与不定代词、冠词、指示代词、形容词性物主代词等被称作限定词。
2. 基数词变为序数词的规则
(1)第1至第19一般是在基数词后加th,但变化特殊的有one—first, two—second, three—third, eight—eighth, nine—ninth, five—fifth, twelve—twelfth。
(2)逢十的twenty, thirty…ninety,分别改y为ieth。如twenty—twentieth, ninety—ninetieth。 (3)表示第几十几或第几百几十几,只需将个位数改为序数词。
如56—fifty-six—fifty-sixth,635—six hundred and thirty-five—six hundred and thirty-fifth
3. 基数词的读写方法
(1)三位数的读写法:个位与十位之间用连字符“-”;百位与十位之间加and;十位为零时也要加and。
365读作three hundred and six-five 605读作six hundred and five
(2) 大于三位数的读写法:从个位起每三位打一个撇号“’”,第一个撇号读thousand,第二个撇号读million,各撇号之间的数按三位及三位以下的数的读法读。
23, 589读作twenty-three thousand five hundred and eighty-nine
6, 632, 900读作six million six hundred and thirty-two thousand nine hundred
28, 000, 000读作twenty-eight million
4. 序数词与冠词
(1)序数词前一般要加定冠词the。
It’s the third time I’ve been here.这是我第三次到这里来。
(2)表示在原有的基础上增加,即“又一,再一”时,用不定冠词。
Shall I ask her a third time? 我还要问她一次吗?
(3)下列4种情况不用冠词。
1. 序数词前已有物主代词或名词所有格时,不能再用冠词。
This is Tom’s second visit to China.她是汤姆第二次访问中国。
2. 表示比赛或考试的名词时,通常省略定冠词。
He was (the) second in the English exam.在这次英语考试中他得了第二名。
3. 序数词被用作副词时不用冠词。
I have to finish my homework first.我得先把作业完成好。
4. 在某些习语中不用冠词。
at first起初, first of all首先, at first sight乍一看。
5. 数词的语法功能
(1)作主语:The second was better.第二个好些。
(2)作表语:She was second in her class.她在班上是第二名。
(3)作宾语:I was among the first to arrive.我是第一批到的。
(4)作定语:There are fifty states in the US.美国有五十个话别州。
