（1）基数词1-12是独立的单词。

（5）三位数以上的基数词，百位数和十位数之间用and连接。
tw hundred and ne, three thusand five hundred and furteen
（6）英语中没有“万”和“亿”这两个单位，在表示“万”和“亿”时，把“万”念成10个千，“十万”念成100个千，“亿”念成100个百万……以此类推。
10,000：ten thusand
100,000: a hundred thusand
100,000,000: a hundred millin
35, 845: thirty-five thusand, eight hundred and frty-five
= 2 \* ROMAN \* MERGEFORMAT II. hundred, thusand, millin 和billin的用法。
hundred, thusand, millin和billin等表示确切数字时，只用其单数形式；但是在表示不确切数字时，要用其复数形式，并且与f连用，表示约数。
e.g:1. There are mre than three hundred days in a year. 一年有三百多天。
2. Thusands f visitrs travel t the Great Wall every year. 每年有成千上万的游客游玩长城。

twentieth, thirtieth, frtieth, fiftieth, sixtieth, seventieth, eighties, ninetieth
（4）21以上非整十基数词变序数词时，只需将其个位数变成序数词，其它位数仍用基数词。
twenty-first, seventy-sixth, tw hundred and eighty-eighth
= 2 \* ROMAN \* MERGEFORMAT II. 使用序数词时，前面经常加上定冠词the。
e.g:1. He is always the first persn t reach schl. 他总是第一个到达学校。
2. This is the third time fr me t g t Beijing. 这是我第三次去北京。
四、各种数的表达
= 1 \* ROMAN \* MERGEFORMAT I. 日期的表达。
英语中的日期表达采用“月、日、年”或“日、月、年”的顺序。年份用基数词表达，日期用序数词表达。
例如：
10月1日：Octber 1st / the first f Octber
2006年7月5日：July 5th, 2006 / the fifth f July, 2006
= 2 \* ROMAN \* MERGEFORMAT II. 时间的表达。
（1）直接表达法
用基数词 + ’clck来表示整点，注意’clck须用单数，可以省略。
例如：
eight ’clck 八点钟，ten (’clck) 十点钟
用基数词按“钟点 + 分钟”的顺序直接写出时间。
例如：
eleven five 十一点零五分，six frty六点四十
（2）间接表达法
如果分钟数少于30分钟，可用分钟 + past + 钟点表示，其中past是介词，意思是“过”。
例如：
twenty past fur 四点二十 eight past ne 一点零八分
如果分钟数多于30分钟，可用（60分钟-原分钟数）+ t +（原钟点数+ 1）表示，其中t是介词，意思是“差”。
例如：
8:35 可表示为twenty-five t nine 差二十五分钟九点，即八点三十五（其中的分钟数twenty-five 是由60分钟减去35分钟得到的；钟点数nine是由8加上1得到的）。
★注意：
= 1 \* GB3 \* MERGEFORMAT ① 当分钟数是15分钟时，可用名词quarter （一刻钟）表示。例如：
7:15可表示为 a quarter past seven， 12:15可表示为 a quarter past twelve

fur inches wide 四英寸宽
表示时间、距离时，用含有数词的名词所有格形式作定语。

a three-mnth-ld baby 一个三个月大的婴儿
a five-day hliday 五天的假期
= 4 \* GB3 \* MERGEFORMAT ④ 复合数词相当于一个形容词，用来修饰名词，不能作表语。
The building is ten meters high.（√）
This is a ten-meter-high building.（√）
The building is ten-meter-high.（×）
This is a ten meters high building.（×）
= 4 \* ROMAN \* MERGEFORMAT IV.分数的表达。
分子用基数词，分母用序数词，分子大于1时，分母加s表示复数。
例如：
1/3 ne third 3/8 three eighths
“分数+f+名词”作主语时，谓语动词单复数，取决于名词的单复数。名词为单数则谓语动词用单数，名词为复数则谓语动词用复数。
e.g:1. Tw thirds f the land is cvered with water. 三分之二的陆地都是被水所覆盖的。
