数词的用法以及练习

数词

数词分基数词和序数词。基数词表示数目，序数词表示顺序。

一、基数词的构成

1．1—12的基数词是独立的单词，即：

2．13—19的基数词以-teen结尾。如：但13，15，18较特殊， 13—15—18—。

3．20—90的整十位均以-ty结尾。如： sixty，venty，但20，30，40，50，80，90较特殊，

20—30—40—50—80— 90—。

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〕，〔千〕，〔百万〕，〔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—-

7．2，510＝two thousand five hundred and ten；84，296＝eight-four thousand two hundred and ninety-six；

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veral或 many。遵循两无原则

9．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；

10．句型：主语＋is ＋about〔大约〕／ over ＝more than〔超过〕／nearly〔接近〕＋具体数词＋meter〔s〕／kilometer

〔s〕／kilo〔s〕long ／ high ／tall ／deep ／away等。如：长江长6300公里。 The Changjiang River is 6，300 kilometres

long．

二、序数词

1．基数词变序数词可利用口诀巧记：“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：，，，eight—eighth nine

—，five—，twelve—，twenty—，forty—fortieth，twenty-five—。

2．其余情况均在基数词后加th。如： six—sixth, nineteen—nineteenth , hundred— hundredth, thousand—thousandth

等。

3、〔3〕序数词的缩写形式为：阿拉伯数字加上这个词的末尾两个字母。

1st 2nd，3rd，4th，20th，21st，22nd，23rd

三、数词的用法

1. 基数词的用法

(1) 基数词在句中主要用作主语、宾语、定语、表语、同位语，例如：

(2) 表示一个具体数字时，hundred, thousand, million一律不用复数；在表示一个不确定数字时则用复数。例如：

Our country has a population of 1,300 million are three thousand students in our school.

After the war, thousands of people became homeless.

(3) 表示“……十〞的数词的复数形式可用来表示人的岁数或年代，例如： He is in his early thirties． He died still

in his forties． This took place in 1930s．

(4) 表示时刻用基数词。例如：

We get up at six.

表示“几点过几分〞，用介词past,但须在半小时以内。例如：

ten past ten, a quarter past nine,half past twelve

表示“几点差几分〞用介词to, 但分数须在半小时以上。例如：

twenty to nine,five to eight,a quarter to ten

表示“几点几分〞还可直接用基数词。例如：

ven fifteen,eleven thirty,nine twenty

2. 序数词的用法〔1〕〔1〕序数词作定语时，一般要与定冠词或物主代词连用。

is their cond son. He is the first one to come here. John lives on the fifteenth floor．〔2〕序数词有时前面可加

不定冠词来表示“再一〞，“又一〞这样的意思，例如： We'll have to do it a cond time．Shall I ask him a third time？

〔3〕表示日期。

.

①年份，每两位数读一个词。②先月后日，日子要读成序数词。③先日后月，加OF。年，月。日的话年放最后，

用逗号隔开。

〔4〕表示分数时，分子用基数词表示，分母用序数词表示。分子大于1时，分母加-s。例如：three fourths,one cond,two

fifths

〔四、数词在生活中的应用

1．钟点的表示：小时、点钟、分钟、秒钟要用基数词。

2．编号的表示：

① Lesson One ＝the first lesson第一课；Bus No．3＝the No．3bus 3路公共汽车；

② 表示住所时不用“No．〞如：302房间—Room 302〔读作：room three o two〕；

③ 如果编号的数词比较长，一般用基数词。如：Page 457第457页；

⑤ ，用基数词，可单个读，重复的数字也可读“double〞，如：3855633—three eight five five〔double five〕 six three

three〔double three〕。

3．年月日的表示：。 4．分数的表达：

5．倍数的表达：一倍用once，两倍用，两倍以上用基数词＋。如：5倍。

6、小数的小数点读作point，零读作o［ｕ］或zero,小数点后面的数字按个位基数词依次读出。

7、百分数(%)，读作per cent (percent),但不论是多少均用作单数形式不能加s。

8、表示日期有两种说法和四种写法，如：2月1号英语表达法为：the first of February而美语为February (the) first,

但其书写上可有四种写法① February 1 ② February 1st ④ 1/2。

五、特殊用法

1．数词作主语，谓语动词用单数。如： Two months is quite a long time．Four and two is six．What's two and three？

2．一个半小时〔一年半，一个半月可类推〕one／an hour and a half ＝。

3．不定冠词用在序数词前表又一、再一。如：I've tried three times，let me try a fourth time．意为：我已经试过三次，

让我再试一次吧。

4、基数词一般是单数形式，但下列情况，常用复数：

a. 与of 短语连用，表示概数，不能与具体数目连 用，如scores of people 指许多人；

b. 在一些表示"一排"或"一组"的词组里；

如：They arrived in twos and threes. 他们三三两两的到达了。

c. 表示"几十岁"；

d. 表示"年代"，用 in +the +数词复数；

e. 在乘法运算的一种表示法里，如：3 x 5 = 15 Three fives is (are) fifteen.

5、 半小时为half an hour, 半天为half a day, 半镑为half a pound, 尽量避免用half a year, half a month, 要用six

months, two weeks 或 fifteen days 要注意的是Half of the work is done Half of the books are sold. 当Half 作名词

时，其谓语动词要看of后面的名词而定。如名词是不可数名词则用单数谓语动词，如是复数名词时，则要用复数谓语

动词。要注意的是一个半的表达法，如：One and a half apples is left on the table.其名词要用复数，但谓语动词则要用

单数。

6、 在句首的数字要用文字而不要用阿拉伯数字，如数字过大则应放于句中，用阿拉伯数字。如：

There are 166 students playing on the ground.

［误］ 60 students are playing on the ground.

［正］ Sixty students are playing on the ground. ［答案］ A.

加 and / plus 减 minus 乘 times 除 divide by
