4.第一百以上的多位序数词 由基数词的形式变结尾部分为序数词形式来表示。
one hundred and twenty-first ,one thousand,three hundred and twentieth

篇4:初中英语数词复习课件
(一)基数词
基数词用来表示数目,或者说表示数量的词叫基数词。最基本的基数词如下表所示。
1 one 11 eleven 100 a hundred
2 two 12 twelve 20 twenty 1000 a thousand
3 three 13 thirteen 30 thirty 1,000,000 a million
4 four 14 fourteen 40 forty 10,000,000 ten million
5 five 15 fifteen 50 fifty 100,000,000 a hundred million
6 six 16 sixteen 60 sixty 1,000,000,000 a billion
7 seven 17 seventeen 70 seventy
8 eight 18 eighteen 80 eighty
9 nine 19 nineteen 90 ninety
10 ten
说明:
1.13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen和fifteen。
2.20—90由个位数加后缀-ty构成,注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。
3.其它非整十的两位数21—99是由整十位数加连字符“-”,再加个位数构成。如: 81 eighty-one。
4.101—999的基数词先写百位数,后加and再写十位数和个位数。如: 691 six hundred and ninety-one。
5.1000以上的基数词先写千位数,后写百位数,再加and,最后写十位数和个位数。
如:5893 five thousand eight hundred and ninety-three。 在基数词中只有表示“百”、“千”的单位词,没有单独表示“万”、“亿”的单位词,而是用thousand(千)和million(百万)来表达,其换算关系为:1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。
7.多位数的读法:
1)1000以上的多位数,要使用计数间隔或逗号“,”。即从个位起,每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand(千),第二个间隔或逗号前是million(百万),第三个间隔或逗号前是a thousand million或a billion(十亿)。
2)每隔三位分段以后就都成了101—999。读的时候十位数(或个位数)的前面一般要加and。如:
888,000,000读作:eight hundred and eighty-eight million。
(二)基数词的用法
1.基数词的复数形式表示大量的数目。
在这种情况下,表示单位的基数词(hundred, thousand, million, billion)不能在词尾加-s。
例如:
two hundred students 二百个学生
five thousand years 五千年
2.基数词的复数形式表示大量的 的数目,在这种情况下,表示单位的基数词词尾加-s,要与of短语连用。
3.基数词在句中的.作用
基数词的作用相当于名词和形容词,它在句子中可充当主语,宾语,表语和定语。
例如:
Three and five is eight. 3+5=8
主语 表语
How many oranges do you want?你要多少桔子?
I want eight. 我要八个。
宾语
There are eight boats in the lake. 湖里有八条小船。
定语
(三)序数词
表示顺序的词,叫序数词。序数词用来表示数词顺序。除特殊情况外,序数词一般都由相应的基数词加后缀-th构成。
请见下表:
第一到第十 第十一到第十九 第二十以上
first eleventh twentieth
second twelfth thirtieth
third thirteenth fortieth
fourth fourteenth fiftieth
fifth fifteenth sixtieth
sixth sixteenth seventieth
seventh seventeenth eightieth
eighth eighteenth ninetieth
ninth nineteenth hundredth
tenth thousandth
说明:
1.英语中表示第一、第二、第三的序数词属特殊形式,要注意它们的拼写。
2.表示“几十”的序数词通常是将基数词词尾y变成i再加上后缀-eth。
3.其余的二位数序数词是以相应的整十基数词加个位序数词。如:fifty-first(第五十一)。
4.少数序数词拼法不规则,如:fifth(第五),eighth(第八),ninth(第九),twelfth(第十二)等。
注意:
1.序数词可缩写为阿拉伯数字加序数词最后两个字母。
例如:
第一:(the) first=1 st
第二:(the) second=2 nd
第三:(the) third=3 rd
第五:(the) fifth=5th
第九十七:(the) ninety-seventh=97 th
第一百零一:(the) one hundred (and)first=101st
2.编了号的事物要用基数词表示顺序,但是基数词要后置。
例如:
第一课:Lesson One
第三十二页:Page 32
第305房间:Room 305
第12路公共汽车:Bas No.12
(四)序数词的用法
序数词和基数词一样,也能起名词或形容词作用,在句子中作主语、表语、宾语和定语。
例如:
The first is bigger than the second. 第一个比第二个大。
主语
Give me the first. 把第一个给我。
宾语
She’s often the first to go to school. 她经常第一个去上学。
表语
We’re going to learn the eighth lesson. 我们将要学习第八课。
定语

篇6:英语数词的使用方法
一、定义与分类
数词是指表示数目多少或顺序先后的词。表示数目多少的数词叫基数词,如 one, five, ten, thirty, sixty-five 等;表示顺序先后的数词叫序数词,如 first, sixth, tenth, twenty-first 等。数词用法相当于名词和形容词,在句中可用作主语、宾语、表语、定语、同位语等。
二、基数词
1. 英语中没有“万”这个读数单位,要表示汉语中的“万”,英语需借用thousand一词,如“一万”用“十个千”表示(ten thousand),“十万”用“一百个千”表示(one hundred thousand)。
2. 用作基数词单位的 hundred, thousand, million, billion 通常不带复数词尾-s,但若用于表示数百、数千、数百万这样的泛指,则用复数。如:
About two thousand people died in the earthquake. 大约有两千人在地震中丧生。
Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。
3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。如:
He is in his early twenties. 他才二十出头
This took place in the 1930s. 这事发生在20世纪30年代。
三、序数词
1. 许多序数词是由相应的基数词后加词尾-th构成的,如four / fourth,six / sixth,ten / tenth,sixteen / sixteenth,但是nine变为序数词是ninth,而不是nineth。
2. twentieth, thirtieth, fortieth 等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th 构成。
3. first, second, third 通常可缩写为1st, 2nd, 3rd。凡是以th结尾的序数词可缩写为“基数词+th”:4th, 5th, 9th, 11th, 60th, 128th等。
4. 非整十的多位数,将个位数变成序数词即可:twenty-first(第21),thirty-sixth(第36),ninety-ninth(第99),three hundred and sixty-fifth(第365)等。
5. hundred, thousand, million 等序数词形式为 hundredth, thousandth, millionth 等。
6. 序数词前通常要用定冠词,但表示考试或比赛等的名次时,通常可省略其前的定冠词。如:
My room is on the second floor and his on the third. 我的房间在三楼,他的房间在四楼。
He was (the) third in the exam. 他考试得了第三名。
注:有时序数词前不用定冠词,而用不定冠词,表示次第在原有基础上的增加。如:
We’ll have to do it a second time. 我们得再做一次序数词前用定冠词和不定冠词的区别在于:定冠词表特指,不定冠词表泛指,有类似another的意思,但比another 的意思更明确。
篇7:高考英语数词知识点
1、动宾从句
大多数及物动词都可以带宾语从句。部分“动词+副词”结构也可以带宾语从句。
动词短语也可以带宾语从句,常见的这些词有:
make sure(确保)、make up one’s mind(下决心)、keep in mind(牢记)
可运用形式宾语it代替的宾语从句
①动词find,feel,consider,make,believe,think等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置。
②有些动词带宾语从句时需要在宾语与从句前加it(双宾语)这类动词主要有:hate,take,owe,have,see to.award,lend.hand,mail,offer,pass,pay,post,read,return,show,teach,tell
2、介宾从句
用whether之类的介词宾语从句。
用that,if引导的介词宾语从句,有时候except,but,besides三个介词后可见到that引导的宾语从句。
形容+宾从句。有些形容词具有动词的含义,所以也可以带一个宾语从句;
例句:
I am sorry I am late.
I am glad that you can join us.
Are you sure his answer is right?
常用来引导宾语从句的形容词有:sure,certain,glad,please,happy,sorry,afraid,satisfied,surprised
3、if与whether
if和whether在作“是否”理解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if。
少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether。
whether后可以加or not,但是if不可以。在不定式前只能用whether。一般“no matter”后表示“是否”用whether而不用if。

篇9:小考英语数词复习
数词
我们学过两类:基数词和序数词。基数用于表示数量多少,而基数词用于表示次序,常在日期中出现。区别:基数词前面没有the序数词前一定要有the。
1、超过二十以上的两位数需要在个位和十位之间加上-。如:21 twenty-one
2、三位数以上的则需要在百位数后再加上and。如:101 a/one hundred and one
3、用基数词来修饰可数名词时,一定别忘了它的复数形式。如:十八个男孩 eighteen boys
4、用基数词修饰不可数名词时,如是复数,变它的量词为复数。
如:两碗米饭 two bowls of rice
5、序数词一般加th,特殊的有:first, second, third, fifth, eighth, ninth, twelfth以及二十及二十以外的整十:twentieth, thirtieth, fortieth… 第几十几:前面整十不变,后面几改为序数词。如:88 eighty-eighth
练一练:
1、请翻译下列短语。
1)60名学生 (2)15本英语书
3)九杯凉水 (4)4个孩子
5)12月31 (6)6月2日
7)第九周 (8)40年前
9)11+7 (10)上学第一天
2、把下列基数词改成序数词。
one--- two--- three--- nine---
fourteen--- twenty--- thirty-five--- eighty-one
