1、数词数词分为基数词和序数词两种，基数词表数目，序数词表顺序。1. 分数表达法：先写基数词表示分子，后写序数词表示分母，如果分子大于 1 时，分母要加 “s”。如：one-fourth, two-fifths, three-tenths2. 小数表达法：小数点写作 point, 小数后的数字应按其数字直接表示出来。如： 18.38可写成：eighteen point three eight。3. 年、月、时间表达法：年份用基数词，日期用序数词，时间用基数词，其顺序由小到大。4. 英语中没有 “万” 和 “亿 ”，要按十进位法来推算。如：35，845，可写成 thirty-five thousan
2、d eight hundred and forty-five。又如：100，000，000 可写成 a hundred million。5. Hundred, thousand, million, dozen, score 这些词前面如又表示具体数字的词，它们不能加 “s”,反之则须加 “s”。如：three hundred people, thousands of people 。6. 两组与数词有关的介词短语： in+定冠词 the+数词的复数形式，表示年代。如：in the 1870s 或 1870s in+物主代词 +数词的复数形式，表示某人的年龄。如：in ones thirties
