备考2025中考英语：三轮冲刺重难点突破特训
重难点03 数词（易错点+中考练场）
【命题规律】
数词重点在于基数词和序数词的转换运用，例如日期 “July 5th” 中 “5th” 是序数词；“hundred”“thousand” 等单位词的规则，具体数字后用单数形式，如 “five hundred”，表示概数时用复数加 “of”，即 “hundreds of” 。
【解答技巧】
1.基数词与序数词转换：日期表达要用序数词，像 “March 8th”（三月八日）。注意特殊序数词的拼写，“twelfth”（第十二）不能写成 “twelveth” 。在表达顺序、排名等情况时也用序数词，“He got the second place in the race.”（他在比赛中获得第二名）。
2.单位词规则运用：明确 “hundred”“thousand”“million” 等单位词的用法。有具体数字修饰时，用单数形式，如 “three thousand”（三千）；表示概数时，用复数加 “of”，“thousands of”（成千上万的） 。
3.特殊表达记忆：记住年龄、年代等特殊表达。年龄用 “in one's + 整十复数”，如 “in his thirties”（在他三十多岁时）；年代用 “in the + 年份复数”，“in the 1980s”（在 20 世纪 80 年代）。

【考点诠释】
在初中英语语法里，数词主要分为基数词和序数词这两类。基数词用于表示数量，像 one（一）、two（二）就是典型的基数词 ；而序数词则用来体现顺序，例如 first（第一）、second（第二）。
基数词的构成遵循特定规则：1 到 12 这几个数字需要单独记忆；从 13 到 19，是在数字后面加 - teen 来构成，像 thirteen（十三）；20 到 90 这些整十数，则是在数字后面加 - ty，比如 twenty（二十）。序数词的构成也有规律：1 到 3 的序数词形式特殊，像 third（第三）；4 到 19 的序数词，在基数词基础上加 - th，例如 fourth（第四）；整十数的序数词，要把词尾的 y 变成 i，再加上 - eth，像 twentieth（第二十）。
数词的功能多样。基数词可以用来表示数量，比如 “five apples”（五个苹果） ；也能表示时间，像 “7:30”；还能描述年龄，如 “15 years old”（15 岁）。序数词主要用于表示顺序，像 “the first prize”（一等奖），或者表达日期，例如 “March 18th”（3 月 18 日）。数词还有一些特殊用法，分数的表达是分子用基数词、分母用序数词，像 three quarters（四分之三）；小数的读法是小数点读作 “point”，比如 0.5 读作 “zero point five”；百分数就是基数词加上 “percent”，55% 就读作 “fifty-five percent”。
此外，使用数词时还有一些要点需要注意：当 hundred（百）、thousand（千）表示确切数字时，用单数形式，例如 “five hundred”（五百）；表示大概数量时，则用复数形式，并且后面要跟 of，像 “hundreds of”（成百上千的）。在表示编号的时候，既可以把基数词放在后面，比如 “Room 101”（101 房间），也可以把序数词放在前面，例如 “the third lesson”（第三课）。
【数词易错点】
基数词的特殊用法？序数词有the没the？
① 基数词与名词构成复合形容词
It is a two-month-old baby.
Here is a five-year plan.
② 基数词用于有编号的事物上时, 结构为“单数名词（大写）+ 基数词（大写）”
Page 11 或 Page Eleven 第11页
Class 8 或 Class Eight 8班
③ 序数词在一般情况下需要加定冠词the。但若有物主代词在前面修饰或表示“又一、再一”时, 不用加the.
This is her eighteenth birthday. 这是她十八岁生日。
We will have to do it a second time. 我们得再做一次。

参考答案
一、
1．D
【详解】句意：——你认为十五岁的孩子应该被允许开车吗？——不。我不这么认为。
考查年龄表达法。fifteen year olds错误表达；fifteen-year-old十五岁的，作定语；fifteen years old十五岁，做表语；fifteen-year-olds十五岁的人。根据“Do you think...should be allowed to drive ”可知，此处表达十五岁的孩子，用复数形式表泛指。故选D。
2．D
【详解】句意：那个国家的地震使成千上万的人无家可归。
考查thousand的用法。当thousand前有具体数字时，不加s不加of；当thousand前无具体数字时，用thousands of。空格前无具体数字，用结构thousands of“数千的”。故选D。
3．A
【详解】句意：作曲家谭盾因赢得奥斯卡奖而闻名，他现在五十多岁。
考查副词最高级和年龄表达。best最好；fifties五十，复数；well好；fiftieth第五十；good好，形容词；fiftieths第五十，复数；better更好。第二空，in one’s fifties在某人五十多岁时，所以可排除选项B和C；第一空，be well known为固定搭配，表示“闻名”，结合语境，指他最为出名的是获得奥斯卡奖，此处应为最高级，意为“最出名的”。故选A。
4．C
【详解】句意：——博物馆人多吗？——是的，每个月有成千上万的人来参观。
考查大数表达用法。thousand与具体数字连用时，不用复数；thousand表示概数时，其前没有具体数字修饰，后加复数形式，与of连用，thousands of 表示“成千上万的”。故选C。
5．A
【详解】句意：中国古代人民花了三百年的时间才建成了长城。
考查hundred的用法。根据“three”可知，此处表示的是具体的数字，hundred不用复数，也不与of连用，A选项符合。故选A。
6．A
【详解】句意：郑钦文，文女王在2024年巴黎夏季奥运会上获得网球金牌后不久，就获得了数百万粉丝。
考查million的用法。空前有数量，故此处用million的原形。故选A。
7．A
【详解】句意：世界上四分之三的书籍和报纸是用英语写的。
考查分数的表达。根据英语语法，分数的表示方式为“基数词+序数词”，当作分子的基数词是1以上的任何数时，作分母的序数词须用复数形式；books and newspapers是主语，be动词用are。故选A。
8．D
【详解】句意：——这所学校有多少名学生？——有200名学生。其中五分之二是外国留学生。
考查基数词及分数的用法。如果thousand“千”前有具体数字，使用原形即可。分数的表达是分子用基数词，分母用序数词，如果分子大于一，分母要在词尾加s。故选D。
9．B
【详解】句意：——中国上海国际儿童图书博览会已经举办了九届。——是的。第九届进博会于2022年12月2日至4日举行。
考查序数词。nine九；ninth第九；nineteenth第十九；ninety九十。根据“has been held nine times.”以及“The...fair was held...”可知博览会已经举办了九届，此处指第九届，用序数词。故选B。
10．A
【详解】句意：——三十加十是多少？——四十。
考查数字运算。forty四十；fifty五十；seventy七十；eighty八十。根据“What’s thirty and ten”以及常识可知三十加十是四十。故选A。
11．C
【详解】句意：十月一日是国庆节。
考查序数词的用法以及常识。one一，基数词；two二，基数词；first第一，序数词；second第二，序数词。根据“The … day of October”可知，此处指十月的第几天，用序数词表示顺序，排除A和B选项。结合选项10月1日是国庆节，故选C。
12．B
【详解】句意：在我们班，大约三分之二的学生不喜欢网上学习，因为他们不能和同学讨论。
考查分数的表达。分数的表达方式为“基数词+序数词”，基数词是分子，序数词是分母，分子大于1时，分母用复数，故“三分之二”为two thirds。故选B。
13．C
【详解】句意：迈克举办了一个派对来庆祝他爷爷八十岁的生日。
考查序数词用法。eighties八十几；eighty八十；eightieth第八十；the eightieth第八十。表示“第几个生日”要用序数词，eighty的序数词是eightieth，且空前有名词所有格grandfather’s，此时序数词前不用the。故选C。
14．A
【详解】句意：——哦，Lisa，你完成作业了吗？——不，还没。我觉得还需要十分钟。
考查代词用法。another三者及以上的另一个；other其他的，表泛指；others其他人或物；more更多。根据“I think it’ll take ten…minutes.”可知，此处指的是“还需要十分钟”，another+基数词+名词=基数词+more+名词，意为“还要……”。因此此处用another。故选A。
15．B
【详解】句意：——第十二届世界运动会将于2025年在成都举行。——我真的很期待，因为世界运动会是一项高水平的国际体育赛事，已经举办了11次。
考查序数词。fifth第五；twelfth第十二；fourteenth第十四；twentieth第二十。根据“because the World Games is a high-level international sports event and has been held 11 times.”可知，世界运动会已经举办了11次，2025年在成都举办的应该是下一届，即第12届。故选B。
16．A
【详解】句意：我们班有40名学生，20名男生和20名女生。
考查数字运算。forty 40；forty-one 41；forty-two 42；forty-five 45。根据“twenty boys and twenty girls”可知，20+20=40。故选A。
17．B
【详解】句意：李欢有一个哥哥和一个妹妹，所以她是家里的第二个孩子。
考查序数词辨析。first第一；second第二；third第三；fourth第四。根据“Li Huan has an elder brother and a younger sister”可知，哥哥是第一个孩子，妹妹是第三个孩子，那么李欢则是第二个孩子，所以此处应填“second”，故选B。
18．C
【详解】句意：这件衣服通常的价格是300元，今天打八折。现在它的价格是240元。
考查数字运算。结合语境可知，原价300元一件的衣服今天可以享受20%的折扣，即打八折，经过简单计算可知，300*0.8=240。故选C。
19．C
【详解】句意：这位女士看起来如此年轻自信，以至于我不敢相信她已经六十多岁了。更令人惊讶的是，她下个月要举办70岁生日派对。
考查年龄段表达。forties四十；fifties五十；sixties六十；seventies七十。“in one’s＋整十的基数词的复数”表示“在某人几十多岁时”，根据“she’ll have her 70th birthday party next month.”可知，她是六十多岁了。故选C。
20．A
【详解】句意：这个地区三分之一的土地被森林覆盖。
考查分数表达及主谓一致。分数的表达方式为“分子用基数词，分母用序数词，若分子超过了1，分母用序数词的复数”，所以“三分之一”为one third；分数作主语时，谓语动词和of后的名词保持一致，land为不可数名词，谓语动词用单数形式，故选A。
21．A
【详解】句意：一年有二十四个节气。
考查基数词的表达。twenty-four二十四，基数词，表达正确；twentieth-four表达错误，序数词只变个位数；the twenty-four二十四，the一般在序数词前；the twentieth-fourth第二十四个，表达错误，只需要个位数变序数词。根据“There are...solar terms (节气) in a year.”可知，这里说一年有二十四个节气，用基数词。故选A。
22．C
【详解】句意：——你叔叔有三个孩子吗？——是的，汤姆是他的第三个孩子。
考查数词。three三，基数词；third第三，序数词。根据“children”可知，第一空指的是三个孩子，填基数词three；根据“Tom is his…child.”可知，此处是说第三个孩子，填序数词third，故选C。
23．B
【详解】句意：在我们学校的图书馆有五千多册书。
考查数词用法。基数词前有具体数字时，不需要用复数形式；无具体数字时，thousands of 表示 “上千的”，是概数。根据“over”可知强调具体数量，此处指“超过5千”，故选B。
24．D
【详解】句意：这所学校的学生超过四千人，其中七分之五的是男生。
考查主谓一致及分数用法。a number of许多；the number of……的数量，表整体，作主语，谓语动词用单数。根据“is more than 4 thousand”可知，第一空指“学校的学生总人数”，需用The number of；分数的表达方式为“分子基数词，分母序数词，分子大于一时，分母加s”，所以七分之五的表达法是“five sevenths”。故选D。
25．D
【详解】句意：这个镇上大约五分之二的学生乘公交车去上学。
考查分数的表达和主谓一致。分数的表达方法是：分子用基数词，分母用序数词，当分子大于1时，分母序数词要用复数。此处五分之二应表达为two fifths；“分数+of+名词”作主语时，谓语动词的单复数形式要根据of后名词的单复数来确定，这里students是复数形式，时态为一般现在时，谓语动词用原形。故选D。
26．D
【详解】句意：立春是一年中的第一个节气。
考查序数词。fourth第四；third第三；second第二；first第一。根据“Lichun (the Beginning of Spring)”可知，立春是一年中的第一个节气。故选D。
27．B
【详解】句意：会议厅里大约有200个座位。
考查大数的表达。当hundred与数词连用时，表示一个具体的数字，后面不加s；当hundred与of+复数名词连用时，表示一个多而不具体的数字，后面加s。选项中AD为错误表达，设空处前是“about”，hundreds of表示“数百的”，是概数，与about冲突，因此应该填确切数字two hundred 。故选B。
28．B
【详解】句意：——我们今晚住哪个房间？——住406房间。
考查房间号的表达方式。在英语中，房间号通常直接用“Room+数字”表示，不需要加冠词“the”或改变数字与“Room”的顺序，故B选项符合结构。故选B。
29．A
【详解】句意：四班五分之四的学生加入了歌唱小组。
考查分数表达和定冠词。第一空分数是由基数词和序数词一起来表示的。基数词作分子，序数词作分母，除了分子是“1”以外，其他情况下序数词都要用复数形式，故排除B和D。第二空根据“Class Four students”可知，此处表特指，需用the修饰“students”。故选A。
30．A
【详解】句意：——中国的人口是多少？——大约14亿。
考查大数的表达。billion十亿，million百万，thousand千。根据常识，中国人口约14亿，用1.4 billion，billion前面有具体数字时，用单数形式，故选A。
31．B
【详解】句意：我们将有一个为期7天的假期。我的父母会把我一个人留下，我会感到孤独。
考查基数词的用法、动词短语和形容词作表语。seven-days, alone, lonely七天，独自一人，孤独的；seven-day, alone, lonely七天的，独自一人，孤独的；seven-day, lonely, alone七天的，孤独的，独自一人；seven-days, lonely, alone七天，孤独的，独自一人。第一个空表示一个“七天的”假期，为定语，基数词与名词构成复合形容词时，词与词之间用连字符，且其中的名词用单数形式，应为“seven-day”；第二个空为动词短语“leave sb alone”，意为“把某人独自留下”；第三个空前有感官动词feel，后加形容词，作表语，lonely意为“孤独的，寂寞的”，带有感彩，此处指我感觉孤独，符合语境，故选B。
32．C
【详解】句意：这些电视节目在20世纪90年代的中国非常受欢迎，但现在没人看了。
考查年代的表达。在英语中，表示“在哪一年”，常用“in+年份”；若表示“在某一年代”，则用“in+the+逢十的基数词的复数”来表示，是固定用法。结合选项，空处应是“in the 1900s”，表示20世纪90年代。故选C。
33．B
【详解】句意：——我了解到，黄旭华在九十多岁的时候仍然努力从事国防研究。——这是真的。他永不放弃的精神给了我很大的鼓励。
考查年龄表达法。in the nineties通常指“在90年代”；in his nineties表示“在他九十多岁的时候”。根据选项可知，此处表示的是“在某人九十多岁的时候”，正确结构为“in one’s+逢十的基数词的复数”，黄旭华是男性，形容词性物主代词用his。故选B。
34．D
【详解】句意：我的妹妹十二岁了。今天是她的十二岁生日。
考查基数词和序数词。twelve十二，基数词；twelfth第十二，序数词。根据“My sister is…years old. And today is her…birthday.”可知，基数词加上years old，表示人的年纪，故第一个空应填入基数词twelve，第二个空应填入序数词twelfth，修饰单数名词birthday。故选D。
35．A
【详解】句意：尼泊尔发生的两次最强地震已造成8000多人死亡。
考查数词。two“二”，是基数词；second“第二”，是序数词；twice“两次；两倍”；a half“一半”。根据“The ... biggest earthquakes”可知，此处强调数量，表示“两次最强地震”，用基数词two。故选A。
36．D
【详解】句意：据《科学》杂志所说，到21世纪90年代末，世界上三分之二的冰川可能会消失。
考查分数和时间表达。two-thirds“三分之二”，分子大于1时，分母要加s，排除B、C；by the end of 2090s“到21世纪90年代末”，用“定冠词+(世纪百位进数+十位年代数)+s”表示年代。故填D。
37．A
【详解】句意：在示意图中，中国家庭生产的其他垃圾比塑料少。
考查常识和数字比较。根据图表中“Other rubbish 13.6%”、“Paper 15.4%”、“Plastic 20.8%”和“Glass 6.9%”可知，中国家庭产生的其他垃圾比纸少，比玻璃垃圾多，比塑料垃圾少，故选A。
38．B
【详解】句意：这个孩子才两岁，所以你不能把他一个人留下。
考查年龄的表达和代词辨析。two years old两岁；two-year-old两岁的；by herself她自己；by himself他自己。根据“The baby is only”可知，这个孩子两岁，此处应用two years old作表语，排除选项C和D；根据“him”可知，这个孩子是男孩，故应用by himself。故选B。
39．B
【详解】句意：——你通常几点起床？——我通常六点半起床。
考查时刻的表达。“六点半”的正确表达为half past six/six thirty。故选B。
40．B
【详解】句意：昨天是星期天。上千上万的人去了公园。
考查数词用法。thousand前有具体的数字时，需要用原形，后面直接接名词；当后接of时，需要变成复数形式，thousands of“成千上万的”。故选B。

【命题规律】
数词重点在于基数词和序数词的转换运用，例如日期 “July 5th” 中 “5th” 是序数词；“hundred”“thousand” 等单位词的规则，具体数字后用单数形式，如 “five hundred”，表示概数时用复数加 “of”，即 “hundreds of” 。
【解答技巧】
1.基数词与序数词转换：日期表达要用序数词，像 “March 8th”（三月八日）。注意特殊序数词的拼写，“twelfth”（第十二）不能写成 “twelveth” 。在表达顺序、排名等情况时也用序数词，“He got the second place in the race.”（他在比赛中获得第二名）。
2.单位词规则运用：明确 “hundred”“thousand”“million” 等单位词的用法。有具体数字修饰时，用单数形式，如 “three thousand”（三千）；表示概数时，用复数加 “of”，“thousands of”（成千上万的） 。
3.特殊表达记忆：记住年龄、年代等特殊表达。年龄用 “in one's + 整十复数”，如 “in his thirties”（在他三十多岁时）；年代用 “in the + 年份复数”，“in the 1980s”（在 20 世纪 80 年代）。

【考点诠释】
在初中英语语法里，数词主要分为基数词和序数词这两类。基数词用于表示数量，像 one（一）、two（二）就是典型的基数词 ；而序数词则用来体现顺序，例如 first（第一）、second（第二）。
基数词的构成遵循特定规则：1 到 12 这几个数字需要单独记忆；从 13 到 19，是在数字后面加 - teen 来构成，像 thirteen（十三）；20 到 90 这些整十数，则是在数字后面加 - ty，比如 twenty（二十）。序数词的构成也有规律：1 到 3 的序数词形式特殊，像 third（第三）；4 到 19 的序数词，在基数词基础上加 - th，例如 fourth（第四）；整十数的序数词，要把词尾的 y 变成 i，再加上 - eth，像 twentieth（第二十）。
数词的功能多样。基数词可以用来表示数量，比如 “five apples”（五个苹果） ；也能表示时间，像 “7:30”；还能描述年龄，如 “15 years old”（15 岁）。序数词主要用于表示顺序，像 “the first prize”（一等奖），或者表达日期，例如 “March 18th”（3 月 18 日）。数词还有一些特殊用法，分数的表达是分子用基数词、分母用序数词，像 three quarters（四分之三）；小数的读法是小数点读作 “point”，比如 0.5 读作 “zero point five”；百分数就是基数词加上 “percent”，55% 就读作 “fifty-five percent”。
此外，使用数词时还有一些要点需要注意：当 hundred（百）、thousand（千）表示确切数字时，用单数形式，例如 “five hundred”（五百）；表示大概数量时，则用复数形式，并且后面要跟 of，像 “hundreds of”（成百上千的）。在表示编号的时候，既可以把基数词放在后面，比如 “Room 101”（101 房间），也可以把序数词放在前面，例如 “the third lesson”（第三课）。
【数词易错点】
基数词的特殊用法？序数词有the没the？
① 基数词与名词构成复合形容词
It is a two-month-old baby.
Here is a five-year plan.
② 基数词用于有编号的事物上时, 结构为“单数名词（大写）+ 基数词（大写）”
Page 11 或 Page Eleven 第11页
Class 8 或 Class Eight 8班
③ 序数词在一般情况下需要加定冠词the。但若有物主代词在前面修饰或表示“又一、再一”时, 不用加the.
This is her eighteenth birthday. 这是她十八岁生日。
We will have to do it a second time. 我们得再做一次。
