最新小学英语中的基数词和序数词(附带练习题)

最新小学英语中的基数词和序数词(附带练习题)

小学英语中的基数词和序数词定义表示数目的词是基数词。

构成最基本的数词如下: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 thirteen, 14 fourteen, 15 fifteen, 16 sixteen, 17 seventeen, 18 eighteen, 19 nineteen, 20 twenty, 30 thirty, 40 forty, 50 fifty, 60 sixty, 70 seventy, 80 eighty, 90 ninety,100 a hundred,1,000 a thousand,1,000,000 a million,1,000,000,000 a billion.基数词1-12 是独立单词,需逐个记忆。

基数词13 - 19是个位数词的词干后加-teen 构成。

其中thirteen, fifteen, eighteen变化不规则。

基数词20—90是在十位数词后面加-ty 构成。

基数词21—99是在十位数词后面加上个位数词合成,中间加上连字符“–”。

例如:21 twenty-one 95 ninety-five基数词三位以上的数词, 在百位和十位之间,一般要用连词“and”。

例如:132 one hundred and thirty-two.1340 one thousand three hundred and forty表示“万”的词英语中没有。

如1万可用10千来表示:ten thousand。

30万可用three hundred thousand 来表示。

初中英语人教七年级上基数词序数词分类及重要用法讲解附练习题(含答案)

初中英语人教七年级上基数词序数词分类及重要用法讲解附练习题(含答案)

人教七年级英语基数词序数词分类及重要用法讲解附练习题(含答案)一、基数词下面把100以内的基数词分为四类。

01第一类:one 一 two 二 three三 four 四five 五six 六seven七 eight 八 nine 九ten 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。

02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。

03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。

04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。

1、第一类:one 一two 二three 三four 四five 五six 六seven 七eight 八nine 九ten 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。
