2024年人教版中考英语基数词详解以及练习
中考英语基数词详解以及练习1）中考英语基数词详解基数词是用来表示数目或者数量的词，没有限定顺序。
从1到100的基数词都有固定的表达形式，其中1~12的基数词较为特殊，需要逐个记忆，如one（1）、two（2）、three（3）等。
而13~19的基数词，除了thirteen（13）、fifteen（15）、eighteen（18）外，其余均在十位基数词后加-teen构成，如fourteen（14）、sixteen（16）等。
对于20~90的整十位数，它们都以-ty结尾，例如twenty（20）、thirty （30）、forty（40）等。
在构成21~99的基数词时，先说“几十”，再说“几”，中间加连字符“-”。
例如，twenty-one（21）、thirty-four（34）、seventy-six（76）等。
基数词在句子中有多种用法。
它可以表示确切的年龄，如“The little girl is six years old.”（这个小女孩六岁了。
）也可以用来表示时间的具体分钟数，如“I'll meet you at ten minutes past eight.”（我将在八点十分和你见面。
）此外，基数词还可以用来描述数量、价格等，如“I have three apples.”（我有三个苹果。
）或“The price of the book is fifty dollars.”（这本书的价格是五十美元。
）另外，基数词在表达倍数、算式等方面也有特定的用法，比如“twice three is six.”（二乘以三等于六。
）或者“five plus five equals ten.”（五加五等于十。
）例句：表示数量：I have seven books on my desk.（我桌上有七本书。
）They planted two hundred trees last year.（他们去年种了两百棵树。

【复习要点】（一）基数词基数词用来表示数目，或者说表示数量的词叫基数词。
最基本的基1 one 11 eleven 100 a hundred2 two 12 twelve 20 twenty 1000 a thousand3 three 13 thirteen 30 thirty 1，000，000 a million4 four 14 fourteen 40 forty 10，000，000 ten million5 five 15 fifteen 50 fifty 100，000，000 a hundred million6 six 16 sixteen 60 sixty 1，000，000，000 a billion7 seven 17 seventeen 70 seventy8 eight 18 eighteen 80 eighty9 nine 19 nineteen 90 ninety10 ten说明：1．13—19是由个位数加后缀-teen构成。
注意其中13、15的拼写是thirteen 和fifteen。
2．20—90由个位数加后缀-ty构成，注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。
3．其它非整十的两位数21—99是由整十位数加连字符“-”，再加个位数构成。
如：81 eighty-one。
4．101—999的基数词先写百位数，后加and再写十位数和个位数。
如：691 six hundred and ninety-one。
5．1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。
如：5893 five thousand eight hundred and ninety-three。
在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和million（百万）来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。
初一基数词序数词练习题(含答案)
一、基数词下面把100以内的基数词分为四类。
1、第一类：one 一 two 二 three 三 four 四 five 五 six 六 seven 七 eight 八 nine 九te n 十eleven 十一 twelve 十二这一类共计十二个单词，在结构上与其他的基数词相比较是特殊的，就象不规则的动词一样，要求逐个的硬背下来，这对学好其他的基数词和序数词都是及其重要的。
2、第二类：thirteen 十三 fourteen 十四 fifteen 十五 sixteen 十六 seventeen 十七eighteen 十八 nineteen 十九这一类基数词共有七个。
它们在结构上有两个特点：一是在发音方面都有两个重音；二是在拼法上都有后缀－teen。
除了thirteen和fifteen之外，都是纯粹地在另一个基数词的后面加上后缀－teen。
但要注意eighteen的拼法，eight本身有t字母，因此只加－een。
3、第三类：twenty 二十 thirty 三十 forty 四十 fifty 五十 sixty 六十 seventy 七十eighty 八十 ninety 九十这类基数词共有八个。
都是十位的整数，均以后缀－ty结尾。
其中sixty、seventy、eighty、ninety 基本上是在相应的基数词后面加上后缀－ty。
但要注意eighty的拼法，eight本身有t字母，因此只加－y。
4、第四类：这一类和很简单，可以看成是一种合成词。
其结构方式是：用十位整数加上个位整数，其间用连字符号“－”连接，表示“几十几”。
这类基数词的变化都是规则的。
如：twenty-one 二十一 forty-six 四十六seventy-eight 七十八 ninety-five 九十五二、序数词下面把1－99的序数词也分为四个类。
1、第一类first (1st) 第一second (2nd) 第二third (3rd) 第三（在括号里的是缩写形式，均在阿拉伯数字后面加上相应序数词的最后两个字母构成，以下各类与此相同。
