新课程标准中,数词的考查包括基数词和序数词,基数词表示数量,序数词表示顺序。它们是互相对应的。如下表所示：
基数词5年1考,序数词5年3考,基数词混搭5年1考。
【巧记口诀】找清规律很容易, 十二以内词名异；十三数到十九去, 后加-teen莫忘记；二十、三十至九十, 整十之后有-ty；如果要说“几十几”, 中间“-”号别丢弃；hundred是“一百”, 请你记住莫大意。
一、基数词1. 基数词的构成(1)1~12逐个记, 见上述表格。(2)13~19：-teen结尾, 注意thirteen, fifteen, eighteen。(3)20~90：-ty结尾, 注意twenty, thirty, frty, fifty, eighty。
(4)21~99：先说“十位” ,再说“个位” ,中间加连字符“-”。如：23 → twenty-three, 34 → thirty-fur, 45 → frty-five(5)101~999先说“百位” ,再加and ,再加后两位数或末位数。如：586 → five hundred and eighty-six, 803 → eight hundred and three
(6)1,000以上,先从右往左数,每三位数加一个“,”。第一个“,” 前为thusand(千),第二个“,” 前为millin(百万),第三个“,” 前为billin(十亿)。如：①1,001 → ____________________________________________ 　②18,423 →_______________________________________________ 　③6,260,309 →___________________________________________________________________________________________________ 　④750,000,000,000 → ___________________________________ 　
ne thusand and ne
eighteen thusand, fur hundred and twenty-three
six millin, tw hundred and sixty thusand, three
hundred and nine　
seven hundred and fifty billin
(7)带小数点的读法。小数点读作pint,小数点后的数字依次用基数词读出。如：1.08读作ne pint zer eight　12.34读作twelve pint three fur
2. 基数词的用法(1)表示时刻。①表示整点。如8：00 a. m. 上午八点　读作：eight (’clck) a. m. 或 eight (’clck) in the mrning②表示非整点(顺读法,先时后分)。如：8：20　eight twenty　　7：40　seven frty　　8：15　eight fifteen以上时刻也可以读作(逆读法,先分后点) ： 8：20　twenty past eight　　7：40　twenty t eight　　 8：15　a quarter past eight
(2)表示加减乘除。如：3+4=7　Three plus fur is seven. 或Three and fur is / equals seven. 7-3=4　Seven minus three is fur. 或Three frm seven is fur. 3×4=12　Three multiplied by fur is twelve. 或Three times fur is twelve. 12÷3=4　Twelve divided by three is fur. 或Three int twelve ges fur.
(3)表示度量衡。句型：主语+is+具体数词+meter(s)/kil(s)+lng/high/tall/deep/away/wide … 注意：far不能与具体数量单位连用,但away可以。如：①长江长6,300公里。The Changjiang River is _________________________. ②它离这里有16公里远。It is _________________________frm here.
6,300 kilmeters
16 kilmeters (away)
二、序数词1. 序数词的构成 基数词变序数词,词尾加上-th (furth, sixth)；注意第一、二、三、五、八、九、十二的序数词分别为：first, secnd, third, fifth, eighth, ninth, twelfth；以y结尾的基数词变序数词, y变ie后加-th (twentieth)；若是碰到第几十几, 前面用基数词, 后面用序数词, 中间加个连字符, 如twenty-first。
【巧记口诀】一,二,三要全变(ne — first；tw — secnd；three — third)；其余都加th, th里有例外, 8去t(eight — eighth), 9去e(nine — ninth)；字母f代ve (five — fifth；twelve — twelfth)；ty变成tie(twenty — twentieth)；若要变化几十几, 只变个位就可以(twenty-ne — twenty-first)。
2. 序数词的用法(1)序数词和冠词连用表示顺序。如：The first truck is carrying a fruit basket. 第一辆卡车载着一个水果篮。注意：下列几种情况不用冠词。a. 序数词前已有物主代词或名词所有格时,不能再用冠词。如：This is Tny’s secnd visit t China. 这是托尼第二次访问中国。汤姆是他们的第二个儿子。Tm is 　　　　　　　　　　　　.  
their secnd sn
b. 表示比赛或考试的名次时, 通常省略定冠词。如：He was (the) secnd in the English exam. 在这次英语考试中他得了第二名。c. 序数词被用作副词时不用冠词。如：I have t finish my hmewrk first. 我得先把作业完成好。d. 在某些习语中不用冠词。如：at first起初　　first f all首先　　at first sight乍一看
(2)年、月、日的表达法。如：2021年9月1日　1st September, 2021= September 1st, 2021(3)和不定冠词连用表示“又一、再一”。如：Jhn failed twice, but he tried a third time. 约翰失败了两次, 但他又试了一次。
三、易错点突破基数词和序数词的混合用法1. 分数的表达法：母序子基。(1)分子是1时,分母用序数词的单数形式。如：ne fifth　1/5(2)分子大于1时,分母用序数词的复数形式。如：three furths　3/4(3)当分母是2和4时,分别可以用half和quarter代替。如：a half　1/2　three quarters　3/4
2. 表示年、月、日时,年用基数词表示,日用序数词表示。如：in nineteen hundred　1900年　　in nineteen five　1905年Octber the first, nineteen frty-nine写作：__________________ 　 3. 基数词和序数词都可以用来给数字编号,用基数词时,名词和数词首字母都要大写。如：Lessn One=the first lessn　第一课
Octber 1(st),1949
4. a+序数词(再一……,又一……)和the+序数词(第……)的区别。如：I’ll see the mvie a secnd time. (再看一次) This is the secnd time I have seen the film. (第二次)
5. 百分数用percent表示,无复数形式。如：frty percent　40%注意：分数和百分数修饰主语时,谓语动词的形式由分数和百分数 所修饰的名词的单复数决定。如：Tw fifths f the land in that district is cvered with trees. 那个地区五分之二的土地被树木覆盖。Tw fifths f the girls in the class have finished their hmewrk. 班上五分之二的女生已经完成了作业。
