考点扫描☆聚焦中考
数词是中考的常考点也是必考点，主要考查基数词、序数词、概数词以及分数的表达。
高频考点一：基数词的用法
1.基数词：表示数量多少的数词。2.序数词：表示顺序的数词
注意：
基数词的用法：用于修饰可数名词，除“1”之外名词都要用复数。
高频考点二：序数词的用法
基数词变序数词口诀:基变序，有规律，
①一般情况直接加-th,如:four---fourth
②一，二，三特殊记，词尾t , d , d .（ one-- first， two-- second， three-- third）
③8去t , 9去e ,ve要用f来代替（five ,twelve 是两兄弟）之后再加-th
eight--eighth， nine-- ninth，five--fifth， twelve→twelfth
④以ty 结尾的整十数，改y为 ie,再加-th.
twenty---twentieth thirty---thirtieth
forty---fortieth fifty---fiftieth
sixty---sixtieth seventy---seventieth
eighty---eightieth ninety----ninetieth
⑤几百几，几十几也容易，只需个位变为序。
2.序数词的用法
序数词的用法：无论序数词的数字有多大,在数量上都只是“1”，所以序数词只能用于修饰单数可数名词。其前必须加定冠词the, 除非有one’s.即：总有这样的标志。the/one’s+序数词+单数名词
高频考点三：分数、百分数的表达及做主语的用法
分数的表达法：分数由基数词和序数词合成。分子用基数词，分母用序数词。分子是1 时，分母用单数形式；分子大于1时，分母用复数形式。
百分数的表达法：百分数由基数词+percent表示。
分数和百分数跟名词做主语，谓语动词的形式由后面的名词决定。
高频考点四：hundred、thousand、million的用法
当这些词与具体数字连用时，习惯上用单数，而且也不后接介词of。当这些词不与具体数字连用，而是表示不确定的泛指数时，则不仅要要用复数，而且要后接介词of，然后才能接名词。
考点剖析☆名师点拨
高频考点剖析一：基数词的用法
数词是表示数量多少或顺序先后的词,数词可以分为基数词和序数词。
100以内的基数词基数词不难记,找清规律很容易,十二以内词各异,十三数到十九,teen莫忘记。二十、三十……至九十,尾巴要加ty。要说“几十几”,中间“-”别丢弃。
若说几百几十几,百位十位用and。以上用法要记住,用时千万莫大意。
典例1：There are ________ months in a year. December is the ________ month of a year.

【答案】C
高频考点剖析二：序数词的用法
1.序数词前要加定冠词the,若序数词前有形容词性物主代词或名词所有格时省略the。

【答案】B
高频考点剖析三：分数、百分数的表达及做主语的用法
1.分数的表达
(1)分子用基数词,分母用序数词;如果分子大于1,分母要用复数形式。
1/6 one sixth 3/4 three fourths 4/5 four fifths
(2)在英语中,“四分之一”常表示为a quarter;“四分之三”表示为three quarters;“二分之一”表示为a half。
2.分数的用法
“分数+of+限定词+名词复数”作主语时,谓语动词应用复数形式;
“分数+of+限定词+不可数名词/名词单数”作主语时,谓语动词常用单数形式。
Two fifths of the students are from China in this school.
这所学校五分之二的学生来自中国。
Two thirds of her money was spent on clothes.

【答案】D
高频考点剖析四：有关数词的一些特殊用法：
1.one 和 two除了变序数词first ，second 还可以变成次数once一次, twice两次
2.序数词在使用时，通常前面要加定冠词the，除非有one's,如果序数词前面有不定冠词a/an时，则表示“再一”，“又一”。
如：I have two apples already, but I want a third apple.
●3.“基数词+more+名词”或“another+基数词+名词”表示在原来的基础上增加的数量。意为“又…”“再…”
如：two more apples=another two apples
●4.“基数词-单数名词”相当于复合形容词，作名词的定语，用于表示时间，距离等。如：two-hour walk=two hours' walk
●5.hundred百,thousand千, million百万. billion十亿等的用法：简单记为：等的用法：简单记为：
①其前没有具体数字时 其后要加-s，要与of连用 ，即“两有”。如： hundreds of
②其前有具体数字时，其后不能加-s，也不能与of连用,即“两无”。如：two hundred
6.基数词也可表示一些编号的顺序，只需将基数词放在单数名词之后，不需要定冠词the，但单词的首字母必须大写。
如：Class Fifty/Class 50 五十班 Room 3 三号房间

基数词和序数词的变化规律
两大数词基和序，前表数量后第几。构成先谈基数词，1至12请认真记。
13至19teen结尾齐，ty结尾表示几十。若要表达几十几，几十短横1到9。
One hundred一百记，若表几百几十几。几百and几十几，基数规律上述里。
再把序数谈仔细，第一至三独立记。第四至十九结尾th，第廿到九十有规律。
基数基础y变ieth。第几十几有特例，第几十由基数起，几用序数有道理。
第一百one hundred，若说第一百几十几。One hundred and第几十几。谈此即告一段落。
序有缩式莫忘记，上述须用心体味。

考点过关☆专项突破
1．（2022·黑龙江哈尔滨·校考一模）Tom who is ________ years old chose the ________ problem. At last, he worked it out and won the game.
A．nineth, forty B．nine, fortith C．nineteen, fortieth
【答案】C
【详解】句意：十九岁的汤姆选择了第四十道题。最后，他算出了答案，赢得了比赛。
考查数词。第一个空表示“……岁”，用基数词表示年龄，故排除A；第二个空前有“the”，说明是序数词，forty的序数词时fortieth。故选C。
2．（2022·黑龙江哈尔滨·校考一模）It’s _______ time since we met last.
A．one and half month’s B．one and a half months C．one and a half months’
【答案】C
【详解】句意：自从我们上个月见面已经有一个半月的时间了。
考查名词所有格和数量表达。“一个半月”可以表达为one month and a half或one and a half months。这里表示已经有一个半月“的”时间了，所以用所有格形式，时间地点的名词的所有格在后面加’s。以s结尾的复数，只加’。故选C。
3．（2022·四川达州·统考一模）________ weeks ________ enough.
A．The third; are B．The third; were C．Three; are D．Three; was
【答案】D

【答案】A
【详解】句意：如今，许多人更喜欢华为手机，他们中大约五分之四的人是成年人。
考查形容词短语和分数的表达。a number of许多，大量的；the number of……的数量。根据“people like HUAWEI phones better,”可知，空一表示许多人，用a number of，排除选项CD；分数的表达法是分子用基数词，分母用序数词，分子大于一时，分母加复数s，因此空二处五分之四表达为four-fifths。故选A。
5．（2022·海南海口·海口市第十四中学校联考三模）On my ________ birthday, my uncle gave me a cool toy car as a present.
A．five B．fifth C．the fifth

考查数词的表达。表示“在某人多少岁时”可用结构“in one’s+整十的复数”，in his thirties“在他三十多岁时”，排除BD；第二个空前有具体的数字，故此处用billion“十亿”，不与of连用。故选A。

考查be动词和数词的用法。the number of表示“……的数量”，跟复数名词连用作主语时，中心词是number，谓语动词要用单数is。因此排除B、D选项。hundred前面有基数词时，用单数来表示具体数字，因此C不正确。故选A。

学案06 数词
备考2023中考英语二轮高频考点剖析学案
考点扫描☆聚焦中考
数词是中考的常考点也是必考点，主要考查基数词、序数词、概数词以及分数的表达。
高频考点一：基数词的用法
1.基数词：表示数量多少的数词。2.序数词：表示顺序的数词
注意：
基数词的用法：用于修饰可数名词，除“1”之外名词都要用复数。
高频考点二：序数词的用法
基数词变序数词口诀:基变序，有规律，
①一般情况直接加-th,如:four---fourth
②一，二，三特殊记，词尾t , d , d .（ one-- first， two-- second， three-- third）
③8去t , 9去e ,ve要用f来代替（five ,twelve 是两兄弟）之后再加-th
eight--eighth， nine-- ninth，five--fifth， twelve→twelfth
④以ty 结尾的整十数，改y为 ie,再加-th.
twenty---twentieth thirty---thirtieth
forty---fortieth fifty---fiftieth
sixty---sixtieth seventy---seventieth
eighty---eightieth ninety----ninetieth
⑤几百几，几十几也容易，只需个位变为序。
2.序数词的用法
序数词的用法：无论序数词的数字有多大,在数量上都只是“1”，所以序数词只能用于修饰单数可数名词。其前必须加定冠词the, 除非有one’s.即：总有这样的标志。the/one’s+序数词+单数名词
高频考点三：分数、百分数的表达及做主语的用法
分数的表达法：分数由基数词和序数词合成。分子用基数词，分母用序数词。分子是1 时，分母用单数形式；分子大于1时，分母用复数形式。
百分数的表达法：百分数由基数词+percent表示。
分数和百分数跟名词做主语，谓语动词的形式由后面的名词决定。
高频考点四：hundred、thousand、million的用法
当这些词与具体数字连用时，习惯上用单数，而且也不后接介词of。当这些词不与具体数字连用，而是表示不确定的泛指数时，则不仅要要用复数，而且要后接介词of，然后才能接名词。
考点剖析☆名师点拨
高频考点剖析一：基数词的用法
数词是表示数量多少或顺序先后的词,数词可以分为基数词和序数词。
100以内的基数词基数词不难记,找清规律很容易,十二以内词各异,十三数到十九,teen莫忘记。二十、三十……至九十,尾巴要加ty。要说“几十几”,中间“-”别丢弃。

1.分数的表达
(1)分子用基数词,分母用序数词;如果分子大于1,分母要用复数形式。

(2)在英语中,“四分之一”常表示为a quarter;“四分之三”表示为three quarters;“二分之一”表示为a half。
2.分数的用法
“分数+of+限定词+名词复数”作主语时,谓语动词应用复数形式;

6.基数词也可表示一些编号的顺序，只需将基数词放在单数名词之后，不需要定冠词the，但单词的首字母必须大写。
如：Class Fifty/Class 50 五十班 Room 3 三号房间

基数词和序数词的变化规律
两大数词基和序，前表数量后第几。构成先谈基数词，1至12请认真记。
13至19teen结尾齐，ty结尾表示几十。若要表达几十几，几十短横1到9。
One hundred一百记，若表几百几十几。几百and几十几，基数规律上述里。
再把序数谈仔细，第一至三独立记。第四至十九结尾th，第廿到九十有规律。
基数基础y变ieth。第几十几有特例，第几十由基数起，几用序数有道理。
第一百one hundred，若说第一百几十几。One hundred and第几十几。谈此即告一段落。
序有缩式莫忘记，上述须用心体味。
分数的表达方法
子基母序 分子大于1 分母加s
