数词专项训练 一、核心知识复习（数词考点梳理） 1. 基数词核心要点 - 基础拼写：1-12为独立单词，13-19以-teen结尾（注意thirteen/fifteen/eighteen的拼写变化），整十数20-90以-ty结尾（twenty/thirty/fifty/eighty需重点记忆），百/千/百万分别为hundred/thousand/million，前面有具体数字时不加s，如three hundred。 - 用法易错点： 1. 表示编号时，基数词放名词后，如Lesson 5、Room 301。 2. 表示“几百/几千”的模糊概念时，用hundreds of、thousands of，需加s和of。 3. 表示年龄时，用基数词+years old，如He is 12 years old. 2. 序数词核心要点 - 变形规则： 1. 特殊变化：one→first, two→second, three→third, five→fifth, eight→eighth, nine→ninth, twelve→twelfth 2. 一般规则：基数词+th，如four→fourth, six→sixth 3. 整十数：变y为ie+th，如twenty→twentieth, thirty→thirtieth - 用法易错点： 1. 序数词前通常加the，如the first day；但前面有形容词性物主代词时不加the，如my first book。 2. 表示日期时，用序数词，如June 1st。 3. 时间与日期表达规则 - 时间表达： 1. 顺读法：小时+分钟，如7:15读作seven fifteen。 2. 逆读法：分钟≤30用past，如7:15读作a quarter past seven；分钟>30用to，如7:45读作a quarter to eight。 - 日期表达： 1. 英式：日/月/年，如1st September, 2025。 2. 美式：月/日/年，如September 1st, 2025。 - 初中衔接提示：数词的主谓一致、分数表达（分子用基数词，分母用序数词，分子大于1时分母加s，如two thirds）是初一上册的高频考点，需提前掌握。 二、分层习题训练 Ⅰ. 写出下列基数词的序数词形式（每题1分，共10分） 1. one → ______ 2. two → ______ 3. three → ______ 4. five → ______ 5. eight → ______ 6. nine → ______ 7. twelve → ______ 8. twenty → ______ 9. thirty → ______ 10. forty → ______ Ⅱ. 单项选择（每题2分，共20分） ( )1.
