加减乘除表示法
❖ 1. “加”用plus，and或add表示； ❖ “等于”用is，make，equal等词表示。 ❖ 2+3= 可表示为：How much is two plus
❖ 在我们班她是第二名。（作表语）
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有所不同： ❖ 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 = 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。

例：456：four hundred (and) fifty-six2.3.有关“零”的各种说法：zero：一般说法，在温度或数学上使用；nil/nothing：在运动比赛中使用；love：在网球比赛中专用；O（读音）：电话或数学用语；cipher：书面语，指符号而不指数目（有时指温度）。
例：零下 10 度：ten degrees below zeroThe result of the match was 5:0.（读作 five (goals to) nil）They won 3:0.（读作 three (to) nothing）Our team leads by 10:0 in the first tennis game.（读作 ten love）Dial 110.If you have no children, enter a cipher in the space on the form.The thermometer fell below cipher yesterday.4.在某些表示概数的习语中（如“成百上千”、“成千上万”等），基数词后要加“-s”。

例：a few thousand(s) of bookssome thousand(s) of soldiers（单用：some thousands）several hundred(s) of workers（单用：several hundred）many million(s) of birds（单用：many millions）6.表示“多少人组成一组，几个一起”时，基数词要用复数形式。
例：The students lined in fives.She counts them in eights.The guests came in twos.（相当于 two by two/two and two）7.“第一名”、“第二名”可用 first，second 表示，并且可用复数形式。
例：几个第 1 名：several firsts3 个第 2 名：three seconds8.在“several/many/基数词 + dozen + 名词”结构中，dozen 使用单数形式。
（当名词前有修饰性成分时，dozen 和名词之间要用 of（不可省略），即“several/many/基数词 + dozen + of + 修饰词 + 名词”，另外，score 的用法和 dozen 相同。
）例：several/many/six dozen eggsseveral/many/six dozen of white birdsseveral/many/six score eggsseveral/many/six score of white birdsI bought several dozen/score these desks. (×)I bought several dozen/score of these desks. (√)9.“(some) dozens/scores of + 复数名词”结构表示“好几十，很多”。
（some dozen/score (of) + …表示“大约 12/20 个...”）例：(some) dozens/scores of children几十个儿童（some 表示“一些”，对含义无影响）some dozen/score (of) children大约 12/20 个儿童（some 表示“大约”，对含义有影响）10.“a dozen + 复数名词”和“a score of + 复数名词”也可表示“很多”。
例：I have been there a dozen times.I have been there a score of times.11.基数词可以表示书页、住所、房间、教室、邮政编码、电话号码等的编号。
（电话号码通常以两个数字读为一组，中间有个小停顿，但以三个数字读为一组的情况也属常见，尤其是当电话号码为六位数或六位数以上时。
电话号码中两个重复的数字，常用 double。
）例：第 8 页：Page eight（P. 8）第 7 行：Line seven（L. 7）唐宁街 10 号：No. 10 Downing Street第 301 房间：Room (No.) 301第 4 教室：Classroom (No.) 4邮政编码：223805（读作：double six o, two three two, double eight）12.罗列几个并列的名词时，前面的若干个名词前用“不定冠词 + 序数词”结构，最后一个名词前用“定冠词 + 序数词”结构。

（①double 可作 n/v/adj/adv。
②double/twice/three times/four times/…等表示倍数时，要放在定冠词、形容词形物主代词或名词所有格之前。
③treble可作 v/adj，通常可以和 triple 互换，但有时只能用 triple，如 the triple alliance。
<2>。
