A. hundred of B. hundreds of C. hundred D. hundreds 答案:C 解析:“hundred”前有具体数字时,用单数形式,且不与“of”连用;“hundreds of”表示“数百的”,前面不能有具体数字。本题中有“three”,所以用“hundred”。 2.The new building is ________ metres high. A. two - hundred - and - twenty - two B. two hundred and twenty - two C. two hundreds and twenty - two D. two hundred twenty – two 答案:B 解析:表示具体数字时,“hundred”不用复数,百位与十位之间用“and”连接,十位与个位之间用“-”连接。所以“二百二十二”应是“two hundred and twenty - two”。 3.My little brother is only ________.

I don't like math. It's too difficult for me. 1.How many students are there in Lucy's class? 答案:There are forty - five students in Lucy's class. 解析:文章第二句明确提到“There are forty - five students in my class.”,所以露西班上有45名学生。 2.How many boys are there in her class? 答案:There are twenty - three boys in her class. 解析:文中提到“Twenty - three of them are boys and twenty - two are girls.”,可知她班上有23名男生。 3.How many classes does Lucy have every day? 答案:Lucy has six classes every day. 解析:根据文中“We have six classes every day.”可知,露西每天有6节课。 4.What are the classes in the morning? 答案:They are English, Chinese, math and P.E. 解析:文中提到“In the morning, we have four classes. They are English, Chinese, math and P.E.”,所以上午的课是英语、语文、数学和体育。 5.Why doesn't Lucy like math?  答案:Because it's too difficult for her. 解析:文章最后提到“I don't like math. It's too difficult for me.”,说明露西不喜欢数学是因为它对她来说太难了。 【知识点清单二】序数词 定义:序数词是表示顺序或等级的数词,译为 “第……”。 【要点精讲】1.序数词的构成规则 分类 构成规则 例句 基数词变序数词的核心规则 记忆口诀 基变序,有规律,词尾加上 -th; 一、二、三特殊记,词尾字母 t, d, d; 八去 t,九除 e,ve 要用 f 替; 整十基数变序数,先把词尾 y 改 i; 若想表示几十几,只变个位就可以。 1-3特殊变化 无规律,需单独记忆 first (1st)、second (2nd)、third (3rd) 4-19基本变化 词尾加 -th (其中 8、9、5、12 需特殊处理) 4 → fourth (4th) 8 → eighth (8th)(去 t) 9 → ninth (9th)(去 e) 5 → fifth (5th)(ve 变 f) 12 → twelfth (12th)(ve 变 f) 整十数 词尾 -y 变 -ie,再加 -th 20 → twentieth (20th) 30 → thirtieth (30th) 几十几 十位用基数词,个位用序数词(仅变个位) 21 → twenty-first (21st) 35 → thirty-fifth (35th) 100 以上 末尾两位按上述规则变化,前面部分用基数词 101 → one hundred and first (101st) 234 → two hundred and thirty-fourth (234th) 2. 序数词的用法:与基数词的区别:基数词表示数量(如 three books),序数词表示顺序(如 the third book)。 用法 详细说明/例句 序数词表顺序时,前面通常加 冠词the。 She lives on the sixth floor.(她住在六楼。) The first lesson is very easy.(第一课很简单。) the 18th bus 十八路公共汽车 表示 “又一、再一”(不强调顺序,而是 “额外” 的意思),用 a/an + 序数词。 Can I try a second time? 我能再试一次吗?

A. thirty - second B. thirty - two C. thirtieth - second D. thirty two 答案:A 解析:表示 “第 32 届” 用序数词 “thirty-second”,注意中间用连字符连接,且十位和个位均用序数词形式(个位 “second” 是序数词)。 5.My brother lives on the ______ floor. It’s very high. A. fifteen B. fifteenth C. fifty D. fiftieth 答案:B 解析:表示 “在第几层楼” 用序数词,“fifteen” 的序数词为 “fifteenth”(第十五),“fiftieth” 是第五十,不符合语境。 二、翻译句子 1.今天是他的第二十个生日。 答案:Today is his twentieth birthday. 解析:“第二十个” 用序数词 “twentieth”,前有 “his”,不加 “the”。 2.请在第三个十字路口右转。 答案:Please turn right at the third crossing. 解析:“第三个” 用序数词 “third”,前加 “the”。 3.这本书有三百页,我最喜欢第十页。 答案:This book has three hundred pages, and I like Page Ten best. 解析:“三百” 用基数词 “three hundred”(hundred 前有具体数字,用单数)。 “第 10 页” 用 “Page Ten”(基数词放在名词后,首字母大写)。 【知识点清单三】分数/百分数 【要点精讲】 1.分数 构成 规则 举例 基数词(分子)和序数词(分母) 分子 ≤ 1:分母用单数序数词 one third(或 a third) 三分之一 one fourth/a fourth(也可写作 one quarter)四分之一  分子 > 1:分母用复数序数词(加 -s)  two fifths三分之二 three fourths(或 three quarters)四分之三 特殊表达半数:常用 half 或 a half 表示。 one half/a half  二分之一 one and a half(后接复数名词,如 one and a half hours) 一又二分之一 四分之几:可用 quarter 代替 fourth。 three quarters 四分之三 分数作主语时的主谓一致分数修饰可数名词复数时,谓语动词用复数。 Two thirds of the students are boys.(三分之二的学生是男孩。) 分数修饰不可数名词或单数可数名词时,谓语动词用单数。 Three fourths of the water is polluted.(四分之三的水被污染了。) One half of the apple is rotten.(半个苹果烂了。) 分数与名词的复合结构可用连字符构成合成形容词,此时名词用单数,且仅作定语。 a one-third share(三分之一的份额)a two-fifths majority(五分之二的多数) 2.百分数 构成 数字 + percent 构成(英国英语中也可写作 per cent),无复数形式。 5% → five percent 75% → seventy-five percent 主谓一致规则 修饰可数名词复数 → 谓语用复数。 60% of the books are mine.(60% 的书是我的。) 修饰不可数名词或单数可数名词 → 谓语用单数。 80% of the work is done.(80% 的工作完成了。) 100% of the apple is eaten.(整个苹果被吃掉了。) 百分数的修饰词可用 about/nearly/almost/over/up to 等副词修饰,表示 “大约 / 几乎 / 超过” 等程度。 Nearly 90% of the students passed the exam.(近 90% 的学生通过了考试。) Over 50% of the land is used for farming.(超过 50% 的土地用于农业。) 2、易混淆场景对比 结构 例句 谓语 解析 分数 + of + 不可数名词 One-third of the money was spent. 单数 money 是不可数名词,用单数 was 百分数 + of + 可数复数 60% of the books are borrowed. 复数 books 是可数复数,用复数 are 分数 + of + 集体名词 Half of the committee agrees with me. 单数 committee 强调整体,用单数 agrees 百分数 + of + 集体名词 75% of the staff are on vacation. 复数 staff 强调个体,用复数 are 3. 易混易错点对比 考点 正确表达 错误表达 解析 分数分母复数 two thirds(三分之二) two third 分子>1 时,分母必须加 -s 百分数拼写 thirty percent thirty percents percent 无复数形式 合成形容词 a one-half chance(二分之一的机会) a one-halves chance 合成词中名词用单数 主谓一致 Three quarters of the cake is gone.

Third four 答案:B 解析:分数的表达方式为:分子用基数词,分母用序数词。分子大于 1 时,分母需加 -s。 因此,3/4 的正确表达是 three fourths(也可写作 three quarters)。 5.The fraction "2/5" should be read as ______. A. Two fifth B. Second fifth C. Two fifths D. Second fifths 答案:C 解析:分子是 2(大于 1),分母用序数词 fifth 的复数形式 fifths,故正确表达为 two fifths。 6. Which of the following is correct? A. 1/3 → One thirds B. 4/7 → Four seventh C. 1/2 → One half D. 5/6 → Five six 答案:C 解析: 1/2 是特殊情况,固定表达为 one half 或 a half,无需加 - s。 其他选项更正: A. 1/3 → One third(分子为 1,分母用单数)。 B. 4/7 → Four sevenths(分母加 - s)。 D. 5/6 → Five sixths(分母加 - s)。 7.How do you say "65%" in English? A. Sixty-five percent B. Sixty-five percents C. Sixty and five percent D. Sixty fifth percent 答案:A 解析:百分数的表达为:基数词 + percent,percent 永远用单数,故正确为 sixty-five percent。 8.Which is the correct translation of "20%"? A. Twenty percents B. Twentieth percent C. Twenty percent D. Two tenth percent 答案:C 解析:20% 直接译为 twenty percent,注意:不用序数词(如 twentieth),排除 B。percent 无复数形式,排除 A。 9."The project is 75% complete." means ______. A. The project is three-four complete B. The project is three fourths complete C. The project is three quarter complete D. The project is third fourths complete 答案:B 解析:75% 可转换为分数 three fourths(或 three quarters)。 A 选项缺少- s;C 选项 quarter 应为复数 quarters;D 选项序数词 third 错误(分子用基数词)。 10."Three tenths" is equal to ______. A. 3% B. 13% C. 30% D. 33% 答案:C 解析:three tenths 表示 3/10,计算为百分数:3 ÷ 10 = 0.3 = 30%。 二. 改错练习:识别并修正句子中的错误: 1.Two third of the books is new. 答案:将“Two third”改为“Two thirds”,“is”改为“are”,即“Two thirds of the books are new.”。 解析:英语中分数的表达,分子大于1时,分母要用复数形式,所以“三分之二”应是“Two thirds”。“Two thirds of + 可数名词复数”作主语时,谓语动词用复数形式,所以用“are”而不是“is”。原句中分数表达错误且主谓不一致。 2.Two thirds of the books are new. (分母加 - s,谓语复数) 答案:该句正确,无需修改。 解析:“Two thirds of the books are new.”符合分数表达以及主谓一致的规则。“Two thirds”正确表达“三分之二”,“books”是复数,“are”与“books”在数上保持一致。 【知识点清单四】倍数(也可以在形容词副词比较级中学习) 【要点精讲】:倍数的构成和用法 构成 用法 例句 一倍 once 二倍 twice 三倍以上 基数词+times A + be +数+ times +形容词比较级+ than + B The road is 3 times longer than that one 这条路比那条路长三倍 This building is twice higher than that one . 这栋楼比那栋楼高二倍。 A + be +数+ times + as +形容词+ as + B The college is twice as wide as that middle school . 这所大学是那所中学的二倍宽 My grandpa is three times as old as I . 爷爷的年龄是我的三倍。 A + be +数+ times + the +名词( size , length , width , depth ) of + B The road is four times the length of that one . 这条公路是那条公路的四倍. The lakeis ten times the depth of the river . 湖的深度是河流的十倍。 【即时训练】 1. The new stadium being built for the next Asian Games will be ______ the present one. A. as three times big as B. three times as big as C. as big as three times D. as big three times as 答案:B 解析:英语中表达倍数的常用结构之一是“倍数 + as + 形容词/副词原级 + as”,表示“……是……的几倍”。选项B “three times as big as”符合该结构;A、C、D选项语序错误,正确形式应为倍数在前,故答案选B。 2. The output of cars in our factory this year is ______ that of last year. A. twice as much as B. twice as more as C. twice of D. twice than 答案:A 解析:“倍数 + as + much(修饰不可数名词) + as”用于比较产量、数量等抽象概念。B选项“as more as”错误,as...as中间用原级;C选项“twice of”搭配错误;D选项“twice than”无此用法,因此选A。 3. This road is ______ that one. A. four times the length of B. the four times length of C. four times as longer as D. four times as length of 答案:A 解析:表达倍数的另一种结构是“倍数 + the + 名词(size/length/width等) + of”,表示“……的长度/大小等是……的几倍” 。A选项“four times the length of”符合该结构;B选项冠词位置错误;C选项“as longer as”中longer应为原级long;D选项结构错误,故选A。 4. Our school is ______ theirs. A. twice larger than B. twice as larger as C. two times larger as D. twice so large as 答案:A 解析:“倍数 + 比较级 + than”也是常见倍数表达结构。A选项“twice larger than”表示“比……大两倍”,符合语法;B选项“as larger as”错误,as...as中间用原级;C选项“larger as”搭配错误;D选项“twice so large as”中so应改为as(肯定句用as...as),因此选A。 5. The price of the house in this area is ______ it was five years ago. A. three times what B. three times that C. three times as D. three times which 答案:A 解析:“倍数 + what从句”结构用于对比抽象数值(如价格、数量等),what在从句中充当表语,相当于“the + 名词 + that” 。A选项“three times what”正确,表示“是……的三倍”;B选项that不能引导此类从句;C选项“as”后缺少成分;D选项which用法错误,因此选A。 原创精品资源学科网独家享有版权,侵权必究! 学科网(北京)股份有限公司 学科网(北京)股份有限公司 学科网(北京)股份有限公司 $$ 编写说明:黑龙江省2026年春季高考一轮复习《英语知识点清单》,依据《中等职业学校英语课程标准》(2020年版)及历年高考真题进行编写。本资料将高考必备知识进行科学划分,系统总结归纳知识点,全面梳理高考题型。本专辑共三大部分:第一部分是按照基础语法知识点编写的语法知识清单,第二部分是针对课程标准和高考真题中高频词汇的语言知识清单,第三部分是依据各个高考题型编写的题型技巧清单。每份资料均配备配套讲义、课件和练习题。 本专题是黑龙江省2026年春季高考一轮复习《英语知识点清单》中语法知识清单的第3个专题,内容为数词。 黑龙江省2026年春季高考一轮复习 英语语法知识清单 专题3 数词(讲+练) 【考点解读】 近三年考卷数词考点集中于:数词与量词搭配(概数用 “millions of + 复数名词”,具体数字用 “数字 + million + 复数名词”);序数词用法(“a/an + 序数词” 表 “又一”,“the + 序数词” 表顺序);分数表达(分子基数词、分母序数词,分子>1 时分母加 - s,且分数作主语时谓语与名词数一致);年龄表达(“in one's + 整十复数”)。复习时注意基数词 / 序数词基本用法、分数表示、数词名词合成形容词用法,尤其注意 million 等特殊数词用法。 数词综述及分类: 数词是数量或数目、顺序的词,根据其不同的功能和用法,可以分为以下几类: 类别 定义 例词 基数词 表示数量或数目 one , two , three , four , five , six , seven , eight , nine , ten , eleven , twelve 序数词 表示顺序或位置 first 第一(1st)、 second 第二(2nd)、 third 第三(3rd) 分数​ 表示整体的一部分 one-third 1/3 ; two-fifths 2/5 a half 1/2 ; a quarter 1/4 百分数 表示百分比 thirty percent 30% one hundred percent 100% 小数​ 表示非整数 zero point five 0.5 three point one four 3.14 倍数​ 表示数量或程度的倍数关系 twice 两倍, three times三倍... four times 四倍 【知识点清单一】基数词 【要点精讲】:基数词是英语中最基本的数词之一。是用来表示数量或数目的词。 1.基数词的构成 分类 构成规则 例句 1-12 的特殊拼写 需单独记忆,无规律可循 1 one,2 two,3 three,4 four,5 five,6 six, 7 seven,8 eight,9 nine,10 ten,11 eleven,12 twelve 13-19 的构成 以 -teen 结尾,注意拼写变化 13 thirteen,14 fourteen,15 fifteen,16 sixteen, 17 seventeen,18 eighteen,19 nineteen 例外:13(thirteen)、15(fifteen)、18(eighteen) 20-90 的整十数 以 -ty 结尾,注意拼写变化 20 twenty,30 thirty,40 forty,50 fifty, 60 sixty,70 seventy,80 eighty,90 ninety 例外:40(forty,无 u)、80(eighty,ie 组合) 两位数(非整十数) 由 “整十数 + 个位数” 构成,中间用连字符 “-” 连接: 21 twenty-one, 35 thirty-five, 78 seventy-eight, 99 ninety-nine 三位数及以上 结构: 百位 + and + 十位 / 个位 101 one hundred and one 325 three hundred and twenty-five 500 five hundred(无十位和个位时,省略 and) 百/千/万及以上 hundred, thousand, million前有数词时用单数,表概数用复数+s+of 1,000 one thousand 10,000 ten thousand 100,000 one hundred thousand 1,000,000 one million 2.基数词的用法 用法 例句 1.直接表示数量(最基本用法) 修饰可数名词复数,置于名词前 five books(五本书), twenty students(二十名学生) 2.表示年龄 作表语:“基数词 + years old”(可省略 years old): She is seven (years old). 她七岁了。 作定语:“基数词 + year-old”(成为复合形容词,year 用单数,加连字符): a three-year-old boy 一个三岁的男孩 an 8- year - old boy 一个八岁的男孩 3.表示时间 整点:基数词 + o’clock(可省略): five (o’clock) 5 点 非整点:时间没过半(分钟 ≤ 30): 小时+分钟 分钟+ past +小时 (几点过几分) seven ten 7:10 twenty past five 5:20 非整点:时间过半(分钟 > 30)小时+分钟: 分钟+ to +小时(“(60 -分钟)+ to + 下一小时” 差几分到几点) five fifty - five 5:55six fifty 6:50 five to six 5:55 ten to seven 6:50 十五分和四十五分的表示 a quarter 十五分钟 five fifteen / a quarter past five 5:15 three forty - five / a quarter to four 3:45 4.表示日期、年份 日期:“月份 + 基数词”(序数词也可,但基数词更口语化): May 1 (或 May 1st) 5 月 1 日 年份:四位数年份分两组读: twenty twenty-three 2023 整百年份: eighteen hundred 1800 two thousand 2000 5.年代、朝代 in the 整十年' s in the 1970' s 二十世纪七十年 in the 整十年 s in the 1950s 二十世纪五十年代 in one ' s +整十年复数 in his forties 他四十多岁时 6. 表示编号、房间号、电话号码等 “名词 + 基数词”(名词在前,数字在后,首字母大写,不加冠词 the) 302 房间 → Room 302 Bus No. 5(或 the No. 5 bus) 5 路公交车 7. 表示度量衡(长度、重量、价格等) 基数词 + 单位名词+ 形容词(long/wide/heavily 等)构成形容词词组,只能做后置定语和表语: a pole 20 meters long 二十米长的杆 The river is 500 kilometres long.(这条河 500 公里长。) 基数词﹣名词﹣形容词构成复合形容词,放在修饰词前作定语,不能作表语 a 20- meter - long pole 一根二十米长的杆 a 4- meter - high wall 四米高的墙 8. hundred, thousand, million , billion等词的用法 1.hundred, thousand, million ,billion等词前有具体数字时,用单数形式,词后不加 s,且不与 of 连用; 300 名工人 three hundred workers(正确) three hundreds workers(错误) 一万 ten thousand(正确)(ten thousands错误) 2.表示 “约数”(成百上千、成千上万)时,hundred, thousand, 等词前面不加数字,用复数形式 + of,词后加 s ,后跟 of hundreds of birds(成百上千只鸟) thousands of people(成千上万的人) Hundreds and thousands of 3.口诀助记,辅助记住基数词的拼写和发音规律 1 - 12的基数词 一二三四五六七,eight、nine、ten来记忆。eleven、twelve特殊记,单独记忆不费力。 13 - 19的基数词 十三到十九,-teen结尾要牢记。thirteen、fourteen很容易,fifteen、sixteen也不难。 seventeen、eighteen有规律,nineteen结尾是 -teen。 20 - 90的整十基数词 二十到九十,-ty结尾是关键。twenty、thirty要记清,forty、fifty也简单。sixty、seventy别混淆,eighty、ninety不难辨。 几十几的基数词 先说几十后说几,中间“-”别忘记。twenty - one二十一,thirty - four三十四。 百、千、万等基数词 hundred是百,thousand是千,million是百万,billion是十亿。 具体数字直接用,不加 -s要记牢。表示概数加 -s,后面再把of来连。 【即时训练】 一、单项选择 1.There are about three ________ students in our school.
