为：the + 序数词 + 名词 / 名词 + 基数词。 ❖ 如：第一次世界大战可以表示为 ❖ the First World War = World War One, ❖ Lesson 8 = the eighth lesson ❖ ②对于一些大序号我们通常只用一种表达法， ❖ 即名词 + 数词。 ❖ 如：501号房间表示为 Room 501, ❖ 538路公共汽车表示为 Bus 538。 ❖ ③可用a / the + number + 基数词 + 名词。 ❖ 如：a No.5 bus一辆五路公共汽车， ❖ the No.8 bus那辆8路公共汽车。

三、数词★基数词表示数量的词叫基数词。

1-12的基数词是独立单词；13-19的基数词都是以-teen结尾的，要注意thirteen，fifteen，eighteen的拼法稍有不同；20-90的十位数，以后缀-ty结尾，要注音twenty，thirty，fifty，eighty的特殊点。

如下表：1基数词的读法⒈三位数的读法：第一个数字+hundred +and+后面的一位或两位数字。

如：107→one hundred and seven；765→seven hundred and sixty-five⒉1,000以上的数的读法：先从后向前数，每三位数加一个逗号，第一个逗号前的数字用thousand（千），第二个逗号前的数字用million（百万），用“几十thousand“表示“几万"，以“几百thousand"表示"几十万”，用“几十million"表示“几千万"，用“几百million"表示"几亿"。

如：13,789,653→thirteen million seven hundred and eighty-nine thousand six hundred andfifty-three2数词的复数形式⒈表示几十岁时。

如“二十多岁”说twenties，表示的是20岁到29岁。

依次类推，thirties 表示“三十几岁"，forties 表示四十几岁”，但十几岁”不可说tens，而要说teens，指13岁至19岁。

如：He died in his thirties.She is in her teens.⒉表示几十年代时。

如：“二十世纪八十年代”写成1980s或1980s，均读作nineteen eighties，指的是1980至1989年这十年间，需注意的是，年代用文字表示时则不可用-s形式。

如：Great changes took place in the l970s.History has entered the eighties.⒊表示不确定数目时。
