1、第二部分 语法专项复习数 词1核心语法概述2语法知识导览3语法精讲精练4核心素养提升 1 核心语法概述 2 数词作为中考的考查点，主要考查考生对数词的构成、表达方式和用法的掌握情况。题型以选择填空和词形变换为主，分值为1至2分。其中，基数词和序数词1至1000的读法和写法，用数字表示时刻、日期、班次、页数、分数和电话号码等常在试题中出现。语法知识导览 3 知识点 1 基数词的构成 记忆口诀：1至12特殊记，13至19加-teen，20至90用-ty 替；十位数后连字符“-”，百位数后and，千位数后分节号“”；百、千若是单数时，其前数字定具体；百、千复数加of，其前数字不具体。注意：当hund

2、red，thousand，million，billion 等数词前有基数词或某些表示数量的形容词时，词尾不加-s。当表示“几百”“几千”“几百万”等笼统数目时，则应该用“-s+of”构成短语。语法精讲精练 4 例题 小试牛刀知识点 2 序数词的构成 1.第一、第二、第三分别为 first，second，third，其拼法与基数词完全不同，要熟记。2.第四至第十九大都是由相应的基数词加 th 构成。注意：fifth，eighth，ninth 和twelfth 的拼法和读法需要特别记忆。3.十位整数的序数词是把相应的基数词词尾 y 变为 ie 再加-th。4.第二十一至第九十九，十位整数用基数词，

3、个位数用序数词，十位数和个位数之间用连字符“-”连接。5.百、千、百万、十亿的序数词分别在相应的基数词后加-th。6.无论一个数目有多大，都是个位数用序数词。5 小试牛刀 例题知识点 3 数词的用法 1.序数词前一般要加定冠词the、物主代词或所有格，修饰名词。2.序数词前加不定冠词 a/an，表示“再一”“又一”的意思。3.编号可用基数词或序数词表示，序数词位于名词之前，并加定冠词，基数词位于名词之后。房间号、公共汽车号、电话号码、页码均用基数词。注意：英语中表示“几个半”的两种表达方法。（1）“数词+and a half+可数名词复数”。（2）“数词+可数名词复数+and a half”。

4、6 小试牛刀 例题知识点 4 时刻表达法 1.顺序法（与汉语相同），即先读整点数，再读分钟数，且都用基数词。2.倒序法。（1）分钟数在半小时前（包括半小时），结构为“分钟+past+点钟”。（2）分钟数超过半小时，结构为“分钟+to+将要到达的点钟”。3.时间为整点时，用“整点时间+oclock”的结构，或省略oclock，直接用整点时间。注意：（1）am 表示上午，pm 表示下午。（2）am/pm 不能和 morning/afternoon 同时使用。7 例题 小试牛刀知识点 5 分数、小数、百分数表达法 1.一般情况下，分子用基数词，分母用序数词。当分子大于 1 时，分母用复数形式。2.小

5、数用阿拉伯数字表示。小数点之前的数按基数词的读法读出，小数点后的数字则一一读出。3.百分数由“阿拉伯数字+%(percent)”构成。percent 没有复数形式。8 例题 小试牛刀知识点 6 年、月、日表达法 年份用基数词表示，一般先读前两位数，再读后两位数；月份的第一个字母要大写；表示日期用序数词或基数词皆可，但一般读成序数词。9 例题 小试牛刀知识点 7 年龄表达法 1.用阿拉伯数字或单词表达年龄。2.表示“几十多岁”时用“in ones 整十的基数词复数形式”的结构。10 例题 小试牛刀知识点 8 年代表达法 用“in the+年代数（世纪百位进数+十位年代数）s”的结构表示。11 例

6、题 小试牛刀知识点 9 由“基数词+连字符+名词+连字符+形容词”构成的形容词 在由“基数词+连字符+名词+连字符+形容词”构成的结构中，名词一般用单数形式。整个结构构成形容词，作其后的名词的定语。12 例题 小试牛刀 常见错误分析 1.基数词和序数词之间的转换混乱。特别是当 twelve 和 twenty 变为序数词时，常分别误写成 twelvfth 和 twentith。2.“基数词+连字符+名词+连字符+形容词”这一结构的用法没掌握好，名词常误用复数形式。13 一、单项选择1.Ann always gets up _.A.at seven thirty B.at thirty seven
