数词

表示"多少"和"第几"的词叫数词。其用法相当于名词或者形容词。数词分为基数词和序数词两种。

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 " - "; 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:

21 twenty –one 95 ninety - five

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。

注意：基数词one, two, three等与hundred, thousand, million, billion连用时hundred, thousand, million, billion后不加s, 如：two hundred, five million; 当不确定数词some, many与hundred, thousand, million, billion连用时hundred, thousand, million, billion后要加s，且后接of, 如：hundreds of; thousands of; millions of; billions of。

2．序数词：表示数目顺序的词用序数词。

1) 序数词1━19 除第一,第二,第三,第五,第八,第九, 第十二变化不规则外，其

余均在基数词后加上 -th。

2) 十位整数的序数词的构成方法是将十位整数基数词的词尾 -y 变成 i 再加 -eth。
