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。

初中英语数词讲解及练习(含答案)(可编辑修改word版)
▲掌握分数、时间、日期的表达法。
【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。
最基本的基数词如下表所示。
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 。
6.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。
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。

3.enty—enty—y的构成方式相同。
4.序数词中的hundred、thousand、n等单位词通常不变,只有在表示序数的时候,才在其后面加上-th。
5.序数词中,除了第一、第二、第三、第五、第八、第九、第十、第十二以及以-ty结尾的序数外,其它序数词的构成方式都是在基数词后面加上-th。
例如:four—fourth。

数词的解说一、定义:表示数目或次序。
二、分类:分为基数词和序数词两种。
表示数目或数目多少的词叫基数词;表示数目次序的词叫序数词。
三、基数词的组成: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 较特别,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 较特别,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-eight406— four hundred and six6) hundred(百), thousand(千), million (百万), billion (十亿)等前方即便有详细的数词, several, some, many 也不可以在它们的后边加-s。
如: six hundred , eight million 。
假如表示不确立数目时,用hundreds of /thousands of /millions of /billions of +名词复数,前方不可以再加数字。
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)。

【点评】考查定语从句的连接词的辨析和序数词。
注意区别定语从句的连接词的使用原则,理解单词词义。

1、第一类:one 一two 二three 三four 四five 五six 六seven 七eight 八nine 九ten 十eleven 十一twelve 十二这一类共计十二个单词,在结构上与其他的基数词相比较是特殊的,就象不规则的动词一样,要求逐个的硬背下来,这对学好其他的基数词和序数词都是及其重要的。
2、第二类:thirteen 十三fourteen 十四fifteen 十五sixteen 十六seventeen 十七eighteen 十八nineteen 十九这一类基数词共有七个。
它们在结构上有两个特点:一是在发音方面都有两个重音;二是在拼法上都有后缀-teen。
除了thirteen和fifteen之外,都是纯粹地在另一个基数词的后面加上后缀-teen。
但要注意eighteen的拼法,eight本身有t字母,因此只加-een。
3、第三类:twenty 二十thirty 三十forty 四十fifty 五十sixty 六十seventy 七十eighty 八十ninety 九十这类基数词共有八个。
