数词用法讲解及练习
数词I.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。
II. 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(from 。
This took place in the 1930s. 这事发生在20世纪30年代。
III. 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。

一、数词讲解1、基数词。
表示数目的多少，如：one, two, three, one hundred, two thousand 等。
2、序数词。
表示顺序第几，其前面须加上定冠词the。
如：the twenty-first, the thirtieth等练习：写出下列数字的基数词和序数词的表示方法。
3、分数。
分数表达法：基数词表示分子，序数词表示分母，如果分子大于1时，分母要加“s”。
如：one-fourth, two-fifths, three-tenths4、年、月、时间表达法：年份用基数词，日期用序数词，时间用基数词，其顺序由小到大。
Eg: He was born on January 11th, 1886. He was born in January, 1990.5、Hundred, thousand, million, dozen, score这些词前面如有表示具体数字的词，它们不能加“s”,反之则须加“s”。
如：three hundred people, thousands of people。

初中英语语法讲解与练习【数-词】
初中英语语法讲解与练习【数-词】数词数词英语数词表示数目或者顺序，可分为基数词和序数词。
基数词表示数量，序数词表示顺序。
知识梳理：提纲挈领，抓住重点和难点！一、基数词的构成1．1-12的基数词是独立的单词，即：one，two，three，four，five，six，seven，eight，nine，ten，eleven，twelve。
2．13-19的基数词以-teen结尾。
如：fourteen，seventeen等，但13，15，18较特殊，13-thirteen 15-fifteen 18-eighteen。
3．20-90的整十位均以-ty结尾。
如：sixty，ninety，但20，30，40，50，80较特殊，20-twenty 30-thirty 40-forty 50-fifty 80-eighty。
4．十位数与个位数之间要加连字符号"-"，如：28-twenty-eight，96-ninety-six。
为序数词时，有特别之处。
1.one--- first, two --- second, three --- third, five --- fifth, nice --- ninth, twelve --- twelfth2. 以ty 结尾的单词，要先变y为I, 在加-eth. 例如：thirty ---thirtieth, fifty ---fiftieth3. 以one, two, three 等结尾的多位数词，要将各位数变成序数词。
例如：twenty-one --- twenty-first, one hundred and one --- one hundred and first注意：序数词前常用定冠词，有时还可以用不定冠词a/an 则表示"又一"的意思。
例如：Mr Brown has a second car. 布朗先生另外还有一辆车。

(3) 20－90的逢十的基数词：分别在2－9的基数词后加－ty构成，即：20－twenty，30－thirty，40－forty，50－fifty，60－sixty，70－seventy，80－eighty，90－ninety。
（注意20，30，40，50，80拼写的特殊变化。
）(4) 21－29的基数词：由十位数20的单词形式twenty加个位数1－9构成。
中间用连字符。
即：21－twenty-one，22－twenty-two，23－twenty-three，24－twenty-four，25－twenty-five，26－twenty-six，27－twenty-seven，28－twenty-eight，29－twenty-nine。
其他的十位数照此类推。

例如：200－two hundred。
有百位数、十位数和个位数的三位数，百位数和十位数之间用and连接。
例如：127－one hundred and twenty-seven。
(6) 千位数是由1－9加thousand构成，后面的百位数、十位数和个位数与前面的构成方法一样。
初中英语数词解题技巧讲解及练习题(含答案)
初中英语数词解题技巧讲解及练习题(含答案)一、初中英语数词1．A year is divided into ______ months. September is the _____ month of the year.A. twelve, ninthB. twelve, ninethC. twelfth, ninthD. twelfth, nineth 【答案】 A【解析】【分析】句意：一年分为十二个月。
九月是一年中的第九个月。
第一个空格后有month，月，可数名词复数monthes，其前要用基数词表示数量。
twelve十二；第二个空格前有定冠词the，空格后有可数名词month，单数，要用序数词表示顺序。
要用ninth第九。
根据故选A。
【点评】考查基数词和序数词。
注意基数词表示数量，序数词表示顺序。
2．—What day is the ______ day of the week?—It's Friday.A. fifthB. fiveC. sixD. sixth【答案】 D【解析】【分析】句意：——一周的第六天是星期几？——星期五。
A.第五；B.五；C.六；D.第六。
星期五是一周的第六天，因此使用sixth，故答案是B。
【点评】考查序数词，追序数词在具体语境中的运用。
3．—Do you know the boy is sitting next to Peter？—Yes. He is Peter's friend. They are celebrating his birthday.A. who; ninthB. that; nineC. which; ninth【答案】 A【解析】【分析】句意：——你知道那个坐在彼得旁边的男孩吗?——是的。
他是彼得的朋友。
他们正在庆祝他的九岁生日。
分析句子结构可知，第一空所在句子是定语从句，先行词是人，连接词在从句中作主语，所以应该用who/that引导，which连接定语从句时先行词应该是物，故排除C；nine九，基数词；ninth第九，序数词；第二空根据空后的birthday为名词单数可知，此处需要序数词，表示某人几岁生日应该用序数词表示第几个生日，故选A。

【复习要点】（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1 one 11 eleven 100 a hundred2 two 12 twelve 20 twenty 1000 a thousand3 three 13 thirteen 30 thirty 1，000，000 a million4 four 14 fourteen 40 forty 10，000，000 ten million5 five 15 fifteen 50 fifty 100，000，000 a hundred million6 six 16 sixteen 60 sixty 1，000，000，000 a billion7 seven 17 seventeen 70 seventy8 eight 18 eighteen 80 eighty9 nine 19 nineteen 90 ninety10 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。

初二上第二单元数词用法讲解与练习英语中的数词包括基数词和序数词两大类，它们的用法非常复杂，为了便于同学们系统地复习数词，现就初中阶段数词的主要内容作以下归纳。
基数词序数词基数词序数词基数词序数词one first thirteen thirteenth thirty thirtiethtwo second fourteen fourteenth forty fortieththree third fifteen fifteenth fifty fiftiethfour fourth sixteen sixteenth sixty sixtiethfive fifth seventeen seventeenth seventy seventiethsix sixth eighteen eighteenth eighty eightiethseven seventh nineteen nineteenth ninety ninetietheight eighth twenty twentieth One hundred One hundredthnine ninth twenty-one twenty-first One hundred and one One hundred and firstten tenth twenty-two twenty-second One hundred andthirty-five One hundred and thirty-fiftheleven eleventh twenty-three twenty-third thousand thousandthtwelve twelfth twenty-four twenty-fourth million millionth一、基本构成(一)基数词——从1数到n1. 1—12的基数词是独立的单词，即：one，two，three，four，five，six，seven，eight，nine，ten，eleven，twelve。
2. 13—19的基数词以-teen结尾。
如：fourteen，seventeen等，但13，15，18较特殊，13—thirteen 15—fifteen 18—eighteen。
3. 20—90的整十位均以-ty结尾。
如：sixty，ninety，但20，30，40，50，80较特殊，20—twenty，30—thirty，40—forty ，50—fifty ，80—eighty。
4. 十位数与个位数之间要加连字符号“-”，如：28—twenty-eight，96—ninety-six。
5. 百位和十位(若无十位则和个位)之间加and，如：148—one hundred and forty-eight ，406—four hundred and six。
6. hundred(百)，thousand(千)，million(百万)，billion(十亿)等前面即使有具体的数词，也不能在它们的后面加s。
如：600—six hundred，8百万—eight million。
但是与“of”，和不确定的数，如some等连用时要加“s”。
7. 1000以上的数字，从后往前数每三位加一个逗号“，”第一个逗号前为千(thousand)，第二个逗号前为百万(million)，第三个逗号前为billion(十亿)。
英语中无“万”这个词，我们可以用“几十个千(th ousand)”表示几万，“几百个千(thousand)”表示“几十万”。
如：2，510＝two thousand five hundred andten；84，296＝eighty-four thousand two hundred and ninety-six；274，350＝two hundred and seventy-four thousand three hundred and fifty。
8. hundred，thousand，million用复数形式修饰名词时要用“of＋复数名词”，如：数以百计的年轻人hundreds of young people；数以千计的书thousands of books。
注意：hundreds of ／thousands of／millions of ＋复数名词，其前面不能加具体的数词，但可加several或many。
Hundreds of new buildings have sprung up here this year.Thousands upon thousands of people in south africa are rising against their oppressors.Thousands and thousands of people come to visit the city every day.Millions of dollars have gone into the building of this factory.(二)序数词——由基数词转变而来，表示“这是第n个”1.口诀巧记基数词变序数词：“一、二、三，特殊记，八去“t”，九去“e”，“ve”要用“f”替，见“y”变成“i”和“e”，词尾加上“th”，若是遇到几十几，只变个位就可以。
”第一、第二、第三分别：first，second，third，eight—eighth nine—ninth，five—fifth，twelve—twelfth，twenty—twentieth，forty—fortieth，twenty-five—twenty-fifth。
2其余情况均在基数词后加th。
如：six—sixth, nineteen—nineteenth , hundred— hundredth, thousand—thousandth等。
3.序数词有时用缩写形式：first----1st, twenty—second-------22th.二、基本用法(一)基数词的基本用法1.定语fifty thousand London Dockers are out on strike.2.主语数词作主语，谓语动词用单数。
如：two months is quite a long time.five is an odd number.3.宾语或介词宾语how many do you want? -----eight, please. the city has a population of four million.4.表语we are altogether fourteen.five plus seven is twelve.5.同位语What work are you to assign us three? Is there room for us two?6. 基数词＋单数名词＋形容词构成合成形容词。
如：一个五岁的男孩a five-year-old boy；一座800米长的桥an 800-metre-long bridge；女子400米接力girls' 400-metre relay race。
7. 句型：主语＋is ＋about(大约)／over ＝more than(超过)／nearly(接近)＋具体数词＋metre(s)／kilometer(s)／kilo(s)long ／high ／tall ／deep ／away等。
如：长江长6300公里。
the changjiang river is 6，300 kilometers long.8.表示“in+one’s +数词的复数形式”可以用来表示人的岁数：in one’s twenties, 在某人二十多岁，in one’s sixties 在某人六十多岁时等。
①he is in his early thirties. ②he died still in his forties.“in+数词的复数形式”表示年代，如：this took place in the 1930s.(二)序数词的基本用法1.序数词主要用作定语，前面一般要加定冠词(或物主代词)：1）tom is their second son.2）they celebrated the 10th anniversary of the founding of the republic.3）I will never give up, not even on the 1,000th or 10,000th try.2.有时前面可以加一个不定冠词a,an来表示“再一”，“又一”这样的意思：1) We’ll have to do it a second time.2) Shall i ask him a third time?3)When I sat down, a fourth man rose to speak.3. first,second 等有时可用来表示“第一个人(批)”“第二个人”等：1) She was among the first to come and settle in Guangzhou2)You will be the second to speak.4.如果数字较长，序数词总避免使用，而且读的方法也常常简化：第201房间：room 201第319面：page 319第一拖拉机厂：the number 1 tractor works 第六号车厢：carriage no.6南京路1490号：1490 Nanjing road电话号码55――2347：telephone number : 55—23475. 在谈编了号的东西时，我们可以用基数词表示顺序：the first part------part onethe third squad------squad threethe twenty-third section----section twenty-three三、特殊数字的表示法(一)年月日表示法1. 年代年代前用in.( in ) 897 读作( in ) eight hundred and ninety-seven( in ) 1961 读作( in ) nineteen sixty-one (或in nineteen hundred and sixty-one)( in ) 1905 读作(in ) nineteen and five( in ) 1800 读作( in ) eighteen hundred2.月份月份开头第一个字母须大写，表示“在某月”时，月份前面用in。
