Ⅰ. 基数词基数词用来表示精确的数量，例如：one, two, three, twelve, eighteen, ninety, hundred, thousand, million, billion等。

基数词有两个后缀：-teen表示“＋10”，例如：sixteen, thirteen等；-ty表示“×10”，例如：sixty, thirty等。

1.2. 100以上的大数词有：a hundred 一百（100）a thousand 一千（1,000）ten thousand 一万（10,000）a hundred thousand 十万（100,000）a million (= a thousand thousand) 一百万（1,000,000）ten million 一千万（10,000,000）a hundred million 一亿（100,000,000）a billion (= a thousand million) 十亿（1,000,000,000）在表示精确数量时不用复数形式，例如：two thousand people两千人，不能说two thousands people。

在表示含糊数量时要用复数形式，例如：thousands of people几千人，不能说thousand of people。

有时，可以在大数词（单数形式）前加上several, a few等词，表示含糊数量，例如：several hundred times好几百次，a few million years几百万年。

100以内的基数词有时也可用复数形式，表示一些特别的意义。

例如：They went to the theatre in twos and threes. 他们三三两两地来到了剧院。

The girl is in her teens. 这个女孩不到二十岁。

He became a professor in his thirties. 他三十多岁时成为了教授。

It was in the 1960s. 那是在二十世纪六十年代。

3. 混合数目的读法：百位以内的数目一般在个位和十位之间加一个and，例如：101 读作：a hundred and one320 读作：three hundred and twenty648 读作：six hundred and forty-eight千位以上的数目从右向左数起，每三位数加一个逗号。

从右开始，第一个逗号处读thousand，第二个逗号处读million，第三个逗号处读billion。

例如：2,648 读作：two thousand six hundred and forty-eight3,008 读作：three thousand and eight16,250,064 读作：sixteen million two hundred and fifty thousand sixty-four5,237,166,234 读作：five billion，two hundred and thirty-seven million，one hundred and sixty-six thousand，two hundred and thirty-four4. “名词＋基数词”结构具有“序列”的意义，例如：Room Four四号房间，相当于the Fourth Room；Lesson Five = the Fifth Lesson第5课。
