高考英语数词知识点复习

高考英语数词知识点复习数词在英语中起着非常重要的作用,它们用来表示数量、顺序和比例等概念。
在高考英语考试中,数词经常出现,掌握数词的用法和规则是提高得分的关键之一。
本文将系统地回顾数词的知识点,帮助大家在高考中取得好成绩。
1. 基数词(Cardinal Numbers)基数词用来表示具体的数量,如1、2、3、10、100等。
在英语中,基数词的表达方式有一些规律可循。
1.1 0-19的基数词对于0-19的基数词,一般采用单词的方式表示,如one(1)、two (2)、three(3)、four(4)等。
需要注意的是,其中11-19的基数词是以“-teen”结尾,如eleven(11)、twelve(12)、thirteen(13)等。
1.2 20-90的基数词20-90的基数词的表达方式与中文类似,采用十位数和个位数的组合。
例如,twenty(20)、thirty(30)、forty(40)、fifty(50)、sixty(60)、seventy(70)、eighty(80)、ninety(90)。
需要特别注意的是,当十位数后接个位数时,一般使用连字符“-”将两个数字连接起来,如twenty-one(21)、thirty-eight(38)等。
1.3 基数词的变形和数词词组有一些基数词在特定情况下需要进行变形。
例如:- 1变为序数词“first”;- 2变为序数词“second”;- 3变为序数词“third”;- 5变为序数词“fifth”。
此外,还有一些表示特定数量的数词词组,如“a half”(一半)、“a quarter”(四分之一)、“a dozen”(一打)、“a couple of”(几个)等。
2. 序数词(Ordinal Numbers)与基数词不同,序数词用来表示顺序、次序和阶级等概念。
在英语中,序数词的构成方式和用法有一些规则。
2.1 构成方式大部分的序数词是在基数词的基础上加上后缀“-th”构成的,如first (第一)、second(第二)、third(第三)、fourth(第四)等。
2021版高考英语一轮复习 语法 数词和主谓一致导学案

数词和主谓一致一、数词考点一基数词1.注意几个不规则的基数词的写法。
如:eleven,twelve,thirteen,fifteen,twenty,thirty,forty,fifty 等.2.英语中的数量以三位为一个单位,一般对应阿拉伯数字的写法每三位加一个逗号,分别是thousand,million和billion。
如:ten thousand=10,000;one hundred million=100,000,000。
3。
数词hundred,thousand,million,billion,dozen,score 表示确切数目时不加-s,但若表示不确切数目时,要用复数形式,与of构成短语.如:一万:ten thousand;成千上万的: tens of thousands of;两打鸡蛋:two dozen eggs;许多鸡蛋:dozens of eggs.We got two hundred story—books.我们弄到了两百本故事书。
There are hundreds of people in the hall。
大厅里有好几百人。
4.年代及年龄表达法表示“某人几十岁"时,用“in one's+逢十的基数词复数”,而“十几岁”不可表示为tens,而要说成teens;表示“……世纪……年代”时,用“in the+逢十的年数后加s或’s”。
如:in his twenties 在他20多岁时in the 1990s∕1990’s 在20世纪90年代考点二序数词1。
序数词前面一般加the,多数序数词由基数词加—th构成。
如:the fifteenth;以y结尾的基数词变化时,先把y改成i,再加—eth。
如:twentieth。
注意几个不规则的序数词的写法。
如:first,second,third,fifth,eighth,ninth,twelfth等。
2。
序数词常可缩写,其形式为阿拉伯数字加序数词的最后两个字母.如:1st,2nd,3rd,4th,21st,22nd,23rd,24th。
高中英语语法复习数词

高中英语语法复习数词英语语法复习之数词高考重点要求:1.掌握基数词、序数词、分数词、倍数、百分数、年月日、钟点、年龄、序号的基本用法。
2.掌握不定数量词、约数词的表达方法。
数词在各个题项中,单选、阅读、听力、写作中发挥着很强的作用,往往用以说明事实的精确性和可信性。
数词是由两大部分构成的即基数词和序数词,而其他数字表示法如分数,小数等均由这两大部分的不同组合而构成。
(一)基数词:表示数目的词为基数词.1~12无规律one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve13~19以teen为结尾thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen20~90以ty结尾twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety21~99十位与个位之间要加连字符“-”twenty-five, sixty-five, ninety-nine101~999百位与十位之间通常用andthree hundred and twenty-five(美语中常将and省略)千以上6275—six thousand two hundred and seventy-five;1200—twelve hundred(二)序数词:表示顺序的数词为序数词.1~19各基数词尾加th其中七个例外:first, second, third, fifth, eighth, ninth, twelfth, 其余,如:four —forth, six —sixth, nineteen — nineteenth20,30~90把y变i后加eth twentieth, fortieth, ninetieth21以后多位数最后一个数用序数词,其余用基数词21st —twenty-first, 110th — one hundred and tenth(三)分数:由基数词和序数词组成。
高三英语教案:数词

高三英语教案:数词第一篇:高三英语教案:数词高三英语语法复习专题(6)Unit6 数词一、考点聚焦1、序号表示法(1)单纯的序号,可在基数词前加number,简写为No.。
如:No.1第一号(2)事物名词的序号表达法有什所不同:①对于一些小序号可有序数词也可用基数词表达,形式分别为:the + 序数词 + 名词;名词 + 基数词。
如:第一次世界大战可以表示为the First World War或World War One。
②对于一些大序号我们通常只用一种表达法,即名词+ 数词。
如:501号房间表示为Room 501, 538路公共汽车表示为Bus 538。
③可用a / the + number + 基数词 + 名词。
如:a No.5 bus一辆五路公共汽车,the No.8 bus那辆8路公共汽车。
2、倍数的表达方式一般情况下我们用以下三种倍数表达方式:(1)倍数用在as + 形容词 / 副词(原级)+ as结构之前。
如:They have three times as many cows as we do.(2)倍数放在形容词或副词的比较级之前或by + 倍数用在比较级之后。
如: This rope is four times longer than that one.They produced more products in 2001 than those in 2000 by twice.(3)倍数用在表示度量名词前,其基本结构为:倍数+ the + size / length / weight … + of + 表示比较对象的名词,也可用于倍数 + what引导的从句中。
如:This room is three times the size of that one.The college is twice what it was 5 years age.You can’t imagine that rats eat 40 to 50 times their weight.3、大约数的表示方法(1)用ten、dozen、score、hundred、thousand、million等数词的复数后加of短语来表示几十、几百、上千、成千上万等大约数概念。
