初中语法专题复习之 数词 重点学习基数词和序数词的构成和用法 考点一 基数词 一、构成： 1. 1-12 的基数词： one, two, three, four, five, six, seven, eight, nine, ten,eleven, twelve 2. 13～19的基数词，在个位数上加后缀 -teen构成，并有两个重音。 thirteen, fourteen, fifteen, sixteen, seventeen, eighteen,nineteen 3. 20～90等十位数由2-9 加后缀-ty构成。 twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety 4. 21-29由十位数20加个位数1-9 构成，十位和个位之间加连字符号"－"，其他十位数以此类推。 21 twenty-one、44 forty-four、98 ninety-eight 5. “几百几十”或者“几百几十几”在“百”后加and。如：156-one hundred and fifty-six,509-five hundred and nine等。 6.四位数或者四位数以上的基数词的拼写规律：用逗号从右往左每三位加一个逗号，第一个逗号读作thousand（千），第二个逗号读作million（百万），第三个逗号读作 billion（十亿）,hundred后别忘了“and”。如： 3,610 读作 three thousand six hundred and ten 94,295 读作 ninety-four thousand two hundred and ninety-five 二、用法： ●倍数、分数、小数、百分数的表示方法：  1.  倍数：time（s） 例如：This room is three times as large as that one. 这个房间有那个房间三个大。 Three threes are nine. or Three times three is nine. 三三得九。 2.  分数：分子用基数词表示，分母用序数词表示，分子为2以上时，分母（序数词）应变为复数。 例如：三分之一，one third 或 a third； 五分之三，three fifths 　　 分数短语作主语时，谓语的数由of 后面的名词来决定，名词为可数名词复数，则谓语用复数；名词为不可数名词，谓语用单数。 例如：A third of the land is covered by forests. Two thirds of the workers are working hard.  3.  小数：小数点前的基数词与前面所讲的基数词读法完全相同，小数点后面则须将数字一一读出。 1.25 读作 one point two five 0.56 读作naught point five six或zero point five six  4. 百分数： 百分号%读作 percent 例如： 5% 读作 five percent ●hundred（百）, thousand（千）, million（百万），billion（十亿）用法： hundred, thousand, million前面有具体数字，要用单数形式，但如果它们后面有of，那它们要用复数形式，同时，前面不能再加具体的数目。 巧记：有具体数字不加s, of; 无具体数字要加s, of。 如： two thousand 两千  thousands of 成千上万 hundreds of 成百上千 millions of 数以百万计 Thousands of people have visited the city. 　　 成千上万的人参观了这座城市。 ●年份表示法：in 1995 在1995年 ●年代表示法：in the 1990s 在二十世纪九十年代 ● “数词－单数可数名词” 或 “数词－单数名词－形容词” 用 "－" 连在一起作定语，修饰名词， 如： an eight-year-old boy 一个8岁的男孩； a seven-day holiday一个七天的假期 ●在某人多少岁时的表达： at the age of+ 基数词 如：at the age of 4 “几十”的复数形式可以用来表示岁数，如：in one’s + 整十的复数 在某人几十岁的时候 如： in his forties 在他四十岁的时候 in one’s teens 在某人十几岁的时候 考点二 序数词 一、构成： 构成方法 示例 1.一般情况在基数词后加-th four → fourth 2.十几-teen结尾加-th thirteen→ thirteenth 3.整十数：基数词尾-ty,改y为i+eth twenty → twentieth 4.遇到几十几，只需把个位变序数词 twenty-four → twenty-fourth 5.百、千、百万直接加th hundred→hundredth thousand→thousandth million→millionth 特殊情况变化 one → first two → second three → third five → fifth eight → eighth nine → ninth twelve → twelfth （序数词的缩写：由阿拉伯数字加上序数词最后两个字母构成。如：first → 1st；second → 2nd third → 3rd ；fourth → 4th） *巧记方法： 一二三单独记，从四开始加th； 五、十二f来把ve替，八加h九去e； 整十变化需注意，ty要变tie再加th。 若是遇到几十几，只变个位就可以。 二、用法： 1.序数词前通常加定冠词the。但如果序数词前有my, your等物主代词或名词所有格等限定词时，不加定冠词the。 2.序数词前有时也用不定冠词a或an，表示“再一；又一”。 如： They have two children, and next year they will have a third child. 3.序数词表示日期，日期可按“日，月，年”的顺序，也可按“月，日，年”的顺序。“日”可用阿拉伯数字，也可用缩写形式的序数词。如：April 1st ，2021 ； 2 May,2022 考点三 数词的其他用法 1. 数词前加every表示“每一段时间或每隔一段时间”。如：every ten days/every ninth day 每10天／每隔9天。 2. 表示倍数关系。“一倍”是once；“两倍”是twice；表示三倍或三倍以上的倍数用“数字+times"-如：三倍 three times；十倍 ten times。 3. 与数目有关的词。如：half一半；second秒；a quarter 四分之一；several 几个；a few 几个；a dozen 一打；a score 二十个。 4. 特殊短语。如：half an hour 半小时；two or three hours=two hours or three 两三个小时；four and a half years=four years and a half 四年半 【活学活用】 写出下列数词的序数词 one __________ two __________ three __________ five __________ twelve_________ eight __________ nine __________ fourteen __________ twenty __________ sixty-six _________ four ________ seven ________ fifteen __________ hundred ______ 【典型例题】 一、用所给词的适当形式填空 1.
