课题四 数 词
语 法
聚焦中考
壹
数词是初中英语语法中要求学生掌握的基本语法之一。数词为实词，在中考题中以听力测试的听填信息题出现概率最大，主要考查学生的听辨能力。结合本专题内容要求，数词的学习需要做到以下几点。
1. 掌握数词的拼写和序数词的构成；
2. 理解基数词和序数词的用法；
3. 掌握日期、年代、时刻和年龄的表达方式。
核心知识点
贰
数词是指表示数目多少或顺序的词。数词和不定代词很相似，其用法相当于名词和形容词。数词有两种：表示数量多少的数词叫基数词；表示数目顺序的数词叫作序数词。
广西近三年中考对数词的拼写少有涉及，而是着重在听力中考查听懂数字正确的读法，在单选题中根据情境选择正确的数词形式以及在阅读题中考察数词的基本用法。
数词的复习可以从下面的知识导图入手。

考点1 基数词
1. 基数词的基本构成
1-10 11-19 整十 几十几(双位数) 其他
one eleven ten twenty-one hundred
two twelve twenty thirty-two thousand
three thirteen thirty forty-three million
four fourteen forty fifty-four billion
five fifteen fifty sixty-five

ten
●口诀记忆
1至12分别记，13至19都带-teen；整十后缀用-ty，双位带上连字符。
【注意】
hundred、thousand、million和billion之类的数词前若有具体数字，数词要用单数，例如：three hundred (300)。当这些数词不表示具体数字时，常用于下列习惯搭配中：hundreds of 成百上千；thousands of 成千上万；millions of 成百上千万的；billions of 数以亿计的，且前面不能有具体的数目。
●易错点
1. 基数词的拼写中，fifteen(15)和forty(40)的拼写最容易出现拼写错误，需独立记背。
2. 大数字的听读写，容易遗漏三位一体中间的0。

基变序，有规律，词尾加上th，123特殊记，结尾分别t、d、d；8减t，9去e，f来把ve替；ty把y改成i，记住th前还有一个e；若是遇到几十几，只变个位就可以，如twenty-first。
