数词的练习与讲解
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。

数词的用法 知识讲解
数词的用法【概念引入】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。
【用法讲解】一、基数词。
1. 基数词的写法或读法。
(1)对于20以内的基本的数字,需要同学们牢记。
要注意其中的一些规律。
例如:13-19的数字都是“-teen”结尾等。
(2)十位数与个位数之间要加连字符。
例如:23→twenty-three(3)百位数与个位数之间要加and。
例如:201→ two hundred and one 642→ six hundred and forty-two 拓展:除此之外,较大的数字是将数字由右向左每三位加一个逗号,使一个数字分成几个小节,第一个逗号前用thousand(千),第二个逗号前用million(百万),第三个逗号前用billion(十亿),然后依次读出(写出)。
例如:68,343 sixty-eight thousand, three hundred and forty-three13, 526, 300 thirteen million, five hundred and twenty-six thousand, three hundred 注意:英语中没有“万”和“亿”这两个单位,只有“百万(million)”和“十亿(billion)”;因此“一万”是用10个千,也就是“ten thousand”来表示的,“一亿”是用“one hundred million”来表示的。
2. 基数词的用法(1)表示确切数目时,hundred,thousand和million只能用单数,不能变复数;但表示不确定的数目时,要用复数形式,并且要加上of。
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。
