数词的用法及训练
数词是表示数量多少或顺序先后的词。分为基数词和序数词。
（一）基数词
1. 表示数量多少的词是基数词，如：one, two, three等。
2. 数词的构成
1）从1－12分别由从one到twelve，12个各不相同的词表示。
one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve
2）从13－19均以后缀-teen结尾。
thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
3）从20－90的整十数词均以后缀-ty结尾。表示“几十几”时，个位和十位之间需加连字符。twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
21 twenty-one 32 thirty-two 43 forty-three
4）整百数由1—9加hundred构成。
100 one (a) hundred 500 five hundred
5) 整百数和整十数之间由and连接，十位与个位之间要加连字符“-”。如果十位数为零，那就在百位和个位之间用and连接。
101 one hundred and two 245 two hundred and forty- five
6）千thousand 百万million 十亿billion
Exercise:

2、序数词
序数词表示排列顺序，如first, second, third等。
构成规则：
1) 序数词第一、第二和第三为first, second和third,其他序数词的构成是在基数词后加th。例如：
six → sixth seven → seventh ten → tenth four → fourth
2) fifth(第五)、eigth (第八)、ninth (第九)和twelfth (第十二)在拼法上有变化。
first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, nineteenth
3) 二十、三十等基数词变为序数词时,要把y变成ie再加-th。例如：
twenty→twentieth forty→fortieth
twentieth, thirtieth, fortieth, fiftieth, sixtieth, seventieth, eightieth, ninetieth
4) 基数词几十几变成序数词时,表示几十的数词不变,只把表示几的基数词变成序数词。例如：twenty-one → twenty-first forty-five → forty-fifth
5）.序数词的缩略形式是由阿拉伯数字加序数词的最后两个字母构成。例如：
1st, 2nd, 3rd, 4th, 21st, 32nd, 40th
6) 序数词前必须加定冠词the
The first time I came to China, I liked it very much.
我第一次来中国，我就非常喜欢这个国家。
The first is always better than the second.第一总是比第二好。
She will choose the third. 她将选择第三。

数词 数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词；表示数目顺序的词叫序数词。 一. 基数词 1. 基数词就注意以下几点： （1）几十几的基数词的十位数与个位数之间要用连字符“-”连接。如： eighty-five 85 twenty-six 26 （2）三位数的基数词须在百位和十位（若无十位则和个位）之间用and连接。如： three hundred and sixty-five 365 two hundred and six 206 （3）基数词的复数形式。当基数词hundred, thousand, million, billion等词前有具体数词或several修饰时，必须用单数。如： several hundred year’s ago几百年前 two thousand students两千个学生 2. 基数词的特殊用法： （1）表示“几十年代”或“几十岁”时，用逢十的基数词的复数形式。如： in the 1990’s 20世纪90年代 in o ne’s twenties在某人20多岁时 （2）用在习语中。如： in twos and threes三三两两地 二. 序数词 序数词应注意的几点事项： 1. 多位数的基数词变成序数词时，只需将末位基数词变成序数词，前边的基数词不变。如： forty-two 42 forty-second第42 nine-hundred 900 nine-hundredth第900 2. 当序数词用阿拉伯数字表示时，必须在数字后加上序数词的最后两个字母。如： 21st第21 32nd第32 3. 序数词前一般要用定冠词the，如果序数词前用a或an时，则表示“又一；再一”（没有具体范围的限制）。如： Though he had failed twice, he wanted to try a third time. 尽管他已失败了两次，他还想再试一次。 The little monkey had had three apples, and he wanted to eat a fourth one. 那只小猴子已经吃了3个苹果，他还想再吃一个。 三. 分数和百分数 1. 分数 （1）分数的分子用基数词，分母用序数词。如： one fifth五分之一 one tenth十分之一 （2）当分子大于1时，分母用序数词的复数。如： two thirds三分之二 five eighths八分之五 （3）当分子是1时，可以用one也可以用a。如： a second = one second a third = one third （4）当分母是2和4时，分别可以用half和quarter代替。如：

A. hundreds; were invited B. hundred; were invited C. hundreds of; invited 【答案】 B 【解析】【分析】句意：上周五有200名学生被邀请参加开幕式。根据题干中的two与选项中的hundred可知此题考查确切数量的表达方式，hundred要用单数形式；students与invite存在动宾关系，此处要用被动语态，由last Friday，可知要用一般过去时，故选B。【点评】考查数量的表达方式以及被动语态。注意确切数量与不确切数量在表达上的不同。 4．We gave away ________ books to the school library last year. A. six thousands B. six thousand C. six thousands of D. six thousand of 【答案】 B 【解析】【分析】句意：去年我们向学校图书馆赠送了六千本书。数词后thousand用单数，thousands of，固定搭配，几千个，不与数字搭配；因此是six thousand或者thousands of，只有B对，故选B。 【点评】考查数词，注意识记thousand的用法。 5．Every year, ________ books are given away to the poor children in the countryside.
英语数词用法归纳 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(from https://www.doczj.com/doc/8d7645065.html,)。 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。 四、分数、倍数、小数和百分数 1. 分数。分数由基数词和序数词构成：分子用基数词，分母用序数词，当分子超过“1”时，分母用复数。如：two thirds=2/3 three fifths=3/5 注：1/2 通常读作a [one] half，一般不读作a second；1/4 可读作a [one] fourth，也可读作a [one] quarter。 2. 倍数。英语中表示倍数时通常借助half, double, twice, three times等之类的词。如： They're twice the size of chickens. 它们比鸡大一倍。 Their house is about three times as big as ours. 他们的房子大约有我们房子三倍大。 3. 百分数。百分数由基数词和百分号(%)组成，百分号(%)读作per cent。如： thirty percent=30% 60 percent=60%
