中考英语复习---数词

表示数目和顺序的词叫数词。数词可以分为基数词和序数词。

一、 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: 1one 11eleven 100a/one hundred 2two 12twelve 20twenty 1,000a/one thousand 3three 13thirteen 30thirty 1,000,000a/one million 4four 14fourteen 40forty 10,000,000ten million 5five 15fifteen 50fifty 100,000,000a/one hundred million 6six 16sixteen 60sixty 1,000,000,000a/one billion 7seven 17seventeen 70seventy 8eight 18eighteen 80eithty 9nine 19nineteen 90ninety 10ten 说明: 1. 11-19是由个位数加后缀-teen构成。注意12,13,15,18的拼写。

2. 20-90(整十)是由个位数加后缀-ty构成。注意20,30,40,50和80的拼写。 3. 其他非整十的两位数(21-99)是由整十数加连字符“-”,再接个位数构成。 Eg. 35: thirty-five 79: seventy-nine 81: eighty-one 4. 101—999先写百位数,后加and,再写十位数和个位数。(百位与十位之间必须加and)

Eg. 108: one hundred and eight 691: six hundred and ninety-one 5. 1001及以上数字:

数字从右往左看,每隔三位划一逗号,倒数第一个逗号前加thousand,倒数第二个逗号前加million,倒数第三个逗号前加billion Eg. 1,954: one thousand nine hundred and fifty-four

712,564,301: seven hundred and twelve million five hundred and sixty-four thousand three hundred and one

812,067,331,991: eight hundred and twelve billion sixty-seven million three hundred and thirty-one thousand nine hundred and ninety-one

6. “hundreds”, “thousands”,”millions” 后加of表示大量的不确定的数目: Eg: hundreds of people 数以百计的人 thousands of trees 成千上万的树 而表示确定的大量数目则直接用基数词,其后不加s,也不加of:

Eg: two hundred students 两百个学生 five thousand years五千年

二、 序数词

序数词用来表示数词的顺序,除特殊情况外,序数词一般都是直接在基数词后直接加后缀-th构成。(见下表) 第一到第十 第十一到第十九 第二十以上 first eleventh twentieth second twelfth thirtieth third thirteenth fortieth fourth fourteenth fiftieth

1

fifth sixth seventh eighth ninth tenth fifteenth sixteenth seventeenth eighteenth nineteenth sixtieth seventieth eightieth ninetieth hundredth thousandth 说明: 1. 英语表示第一、第二、第三的序数词属于特殊形式:first second third 2. –ve结尾的改为fth 3. –ty结尾的改为tieth

4. 两位数以上的序数词,仅个位数部分用序数词,其余部分仍用基数词。 Eg. fifty-first(第五十一) forty-eighth(第四十八)

6. 使用序数词时一般在前面加定冠词the,如:I‘m in the third grade. 但当名词前有物主代词、指示代词修饰时,the 一定要省略。如:in his third year 7. 序数词可缩写为阿拉伯数字加序数词最后两个字母。

Eg. 第一(the) first(1st) 第二(the)second(2nd) 第三(the)third(3rd)

第九十七(the)ninety-seventh(97th)

第一百零一(the)one hundred and first(101st)

8. 编了号的事物要用基数词表示顺序,但是基数词要后置。 第三十二页:Page 32 第305房间:Room 305 第五课:Lesson Five 第12路公汽:Bus No.12

数词的用法:

1. 分数表达法:

基数词做分子,序数词作分母;当分子超过1时,分母要加“s”. Eg: 1/5: one fifth 2/3: two thirds 1/2: one/a half

1/4: a quarter/ one fourth 3/4: three quarters/ three fourths 2. 年月日表达法:
