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：
【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。
考频：基数词5年1考，序数词5年3考，基数词混搭5年1考。
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，56 → fifty-six，67 → sixty-seven(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 → ___________________（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
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
2. 基数词的用法 （1）表示时刻。如：（表示整点）：8:00 a.m.上午八点　读作：eight ('clck) a.m.或 eight ('clck) in the mrning2:00 p.m.下午两点　读作：tw('clck) p.m.或 tw ('clck) in the afternn(顺读法，先点后分)：8:20　eight twenty　　7:40　seven frty　　　8:15　eight fifteen　　10:30　ten thirty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　10:30　half past ten
(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离这里有十六公里远。 It is ___________________ frm here.
6, 300 kilmeters lng
16 kilmeters (away)
3.基数词的特殊用法 (1)“in＋形容词性物主代词＋twenty，thirty等整数的复数形式”，表示“某人几十岁时”。表示人的具体年龄，可直接用基数词。如：He is in his early thirties. 他三十出头。My sister is seven (years ld)．我妹妹7岁了。她在四十几岁就去世了。She died ______________．注：十几岁　in ne’s teens
in her frties
(2)“in＋the＋逢十的基数词的复数形式 / 所有格形式”，表示年代。如：This stry tk place in the 1930s / 1930’s. 这个故事发生在20世纪30年代。有时在年代前可加上形容词early 或late。如：in the early 1860s　在19世纪60年代早期； in the late 1970s　在20世纪70年代晚期
(3)hundred，thusand，millin，billin与具体数词连用，用单数形式。复数形式常与f连用，构成hundreds f，thusands f，millins f，billins f结构，后面接复数名词，表示不确定的数目，可与several，many等表示不确定数目的词连用。如：Several hundreds f children lst their lives in the war. 成百上千名儿童在战争中丧生。森林里有成千上万棵树。There are __________________ in the frest.
thusands f trees
(4)“一个半”之类的表达可用“a / an / ne＋单数名词＋and a half”或“ne and a half＋复数名词”。如：an / ne hur and a half＝ne and a half hurs　 一个半小时(5)“一两天”之类的表达： a day r tw＝ne r tw days (6)表示次数、倍数。如：nce　一次　twice　两次　three times　三次(三次以上可用“基数词＋times”表达)twice a day　一天两次
(7)由“基数词-单数名词-形容词”构成的合成形容词，只能做前置定语，即放在名词前。如：He is an eight-year-ld by. 他是一个八岁的男孩。(8)位于anther之后，mre之前，表示“再多……”如：Can yu have anther tw cakes？ ＝Can yu have tw mre cakes? 你能再吃两块蛋糕吗？
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、含有数词的词组1. hundreds f　数百的，数以百计的2. thusands f　数千的，数以千计的3. millins f　数百万的 4. billins f　数十亿的5. hundreds f millins f　数亿的 6. nce r twice　一两次，偶尔7. in the 1990s　在20世纪90年代 8. in her fifties　在她五十几岁的时候9. at the age f 20　在20岁的年纪 10. half an hur　半小时11. ne by ne　一个个地 12. ne anther　互相
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 / 42．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(1949年10月1日)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)
Octber 1(st)，1949
5．百分数用percent表示，无复数形式。如：frty percent　40%注意：1.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。
2．tw ut f five和tw fifths有区别，前者译作“五分之二的”，作形容词用，可直接跟名词或名词词组的复数形式。如：tw ut f five students五分之二的学生；后者译作“五分之二”，作名词用，不能直接跟名词或名词词组，需要接“f”。如：tw fifths f the visitrs　五分之二的游客
注意：1.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。
数词在语法选择和短文填空中考查得比较少，一般考查hundred，thusand，millin等词的用法，即具体数字和概数的表达，或是 fr the first time，the first ＋ n．等用法。如：1．(2017·广州·6题)He was tired f staring at ________ pigs，hens，cws and sheep.A．hundred B．hundreds C．hundredth D．hundreds f【答案剖析】hundreds f表示“成百上千的”，此处表示成百上千的猪，母鸡，奶牛和羊。故选D。
2．(2016·广州·2 题)At the end f every grwing seasn，________ ptates were dug ut f the grund，and readied fr market.A．thusand with B．thusands with C．thusand f D．thusands f【答案剖析】考查数词中的固定搭配，根据此句前面没有具体的基数词修饰，并结合语境可知这里的数量是约数概念，指“成千上万”的土豆，形容土豆之多，应该用固定表达thusands f。故选D。
