一、序号表示法 1．单纯的序号，可在基数词前加 number，简写为 No. 如：No.1 第一号 2．事物名词的序号表达法 1)对于一些小序号可用序数词也可用基数词表达，形式分 别为：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 或 World War One。 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 5 路公共汽车 the No.8 bus 那辆 8 路公共汽车
二、倍数的表达方式 一般情况下我们用以下三种倍数表达方式： 1．倍数用在 as＋形容词/副词(原级)＋as 结构之前。如： They have three times as many cows as we do. 2．倍数放在形容词或副词的比较级之前或 by＋倍数用在 比较级之后。如： This rope is four times longer than that one. They produced more products in 2001 than those in 2000 by twice.
3．倍数用在表示度量名词前，其基本结构为：倍数＋the ＋size/length/weight ?＋of＋表示比较对象的名词，也可用于 倍数＋what 引导的从句中。如： This room is three times the size of that one. The college is twice what it was 5 years ago. You can't imagine that rats eat 40 to 50 times their weight.
三、大约数的表示方法 1．用 ten，dozen，score，hundred，thousand，million 等 数词的复数后加 of 短语来表示几十、几百、上千、成千上万 等大约数概念。如： The little boy buys dozens of pencils every term. Thousands of people died in the earthquake. Every year tens of thousands of people go to work in Guangdong Province.
2．用 less than，under，below，almost，nearly，up to 等 来表示小于或接近某数目。如： He is good at English, so he can finish the paper in less than two hours. 3．用 more than，over，above，beyond，or more 等来表示 超过或多于某个数目。如： Peking University has a history of more than 100 years.
4．用 or、or so、about、around、some、more or less 等表 示在某一数目左右。如： About 50 people were present at that time. 5．用 to，from?to?，between?and?表示介于两数词之 间。如： His salary rises from 20 dollars a week to 35 dollars a week. 6．注意事项：dozen，score，hundred，thousand，million 作数词表示确切数量时，不用复数。如：three score, five dozen, seven million 等。
四、 分数的表达方式 1．分子用基数词，分母用序数词，分子大于 1 时，分母 用复数。如： onethird 三分之一，threesevenths 七分之三 2．分子与分母之间加 in, 分子在前，分母在后，分子分母 都用基数词。如： one in ten 十分之一，five in eight 八分之五 3．分子与分母之间加 out of, 分子在前，分母在后，分子 分母都用基数词。如： one out of ten 十分之一，five out of eight 八分之五
五、 百分数的表示法 1．表示百分数时直接将数词放在单词 percent 前面即可， 如： twenty percent 百分之二十 2．分数和百分数后面不能直接接名词或代词，而用以下 形式：分数/百分数 ＋of＋冠词/限定词＋名词/代词，其谓语动 词与 of 后的名词在人称和数上保持一致，如： Twothirds of the money was spent on food. About seventy percent of the earth surface is covered by water.
六、 小数的表示法 如：9.65 表示为 nine point six five 218．39 表示为 two hundred and eighteen point three nine
