数词
班级______ 姓名______ 学号______
一、基数词：表示数目的词叫基数词。
（一）基数词的表示方法
1、最基本的基数词
1 one 13 thirteen 20 twenty
2 two 14 fourteen 30 thirty
3 three 15 sixteen 40 forty
4 four 16 seventeen 50 fifty
5 five 17 eighteen 60 sixty
6 six 18 nineteen 70 seventy
7 seven 19 80 eighty
8 eight 90 ninety
9 nine 100 a hundred
10 ten 1,000 a thousand
11 eleven 1,000,000 a million
12 twelve
2、三位以上的基数词，在百位和十位之间一般要用连词and。
1,342 one thousand, three hundred and forty-two
3、英语中没有“万”和“亿”这两个基数词，在表示“万”和“亿”时，要按十进位来推算。
10,000可写成ten thousand
100,000,000可写成a hundred million
35,845可写成thirty-five thousand, eight hundred and forty-five
4、hundred, thousand, million, billion, dozen, score 这些词前面如果有表示具体数字的词，它们末尾不能加“s”且不能与of连用；反之则末尾需加“s”，与of连用。
three hundred people; thousands of people
5、基数词的读法：从后往前数，每隔三位加一个逗号。第一个逗号前读thousand，第二个逗号前读million，第三个逗号前读billion。年代的读法是两位两位地读。
（二）基数词的用法
1、从句子成分上分析，基数词在句中可用作主语、宾语、表语等。
Four of them went to the factory. 他们中的四个人去了工厂。（主语）
I want two. 我要两个。（宾语）
My classmate is eighteen. 我的同学18岁月。（表语）
2、用基数词表示编号。
Today we are going to study Lesson Five. 今天我们要学习第五课。
He lives in Room 801. 他住在801房间。
3、基数词表达钟点。
（1）先点后分，顺读法。如：8:53 eight fifty-three。
（2）先分后点，倒读法。前半小时用“分钟数+past+已过钟点数”；后半小时用“（60-分钟数）+to+下一个钟点数”；正好半点用“half past+已过钟点数”；一刻“quarter”。如：7:20 twenty past seven; 6:35 twenty-five to seven; 1:58 two to two; 8:30 half past eight; 9:15 a quarter past nine; 9:45 a quarter to ten。
4、表示大几倍或者小多少用基数词。
This room is three times bigger than that one. 这个房间比那个房间大三倍。
5、表示带有小数的词用基数词。小数点前的整数按基数词的规则表示，小数点写作point，小数点后的数字应按数字顺序直接表示出来，即“见几读几”。
18.38 可写成 eighteen point three eight。
6、“数词+名词（+形容词）”构成复合形容词作定语，其中名词用单数形式，数词与名词及形容词之间用连字符“-”。
A twenty-one-year-old girl is behind me. 一位21岁的女孩在我身后。
7、两组与数词有关的介词短语：
（1）in+定冠词the+整十基数词的复数形式，表示年代。
In the 1870s 在19世纪70年代
（2）in+物主代词+整十基数词的复数形式，表示某人的大约年龄。
in one’s thirties 在某人30多岁的时候
有时在物主代词后面可加上形容词early或late使其含义更确切一些。
The young man is in his early thirties. 这个年轻人刚30岁出头。
注意：“十几岁”要用in one’s teens，不可以说in one’s tens。
二、序数词：表示数目顺序的词叫序数词。
（一）序数词的构成
写法口诀：1.2.3特殊记，th从4加起，两个ve ，f替，8去t 9去e，ty变成tie，后加th莫迟疑，若是几十几，只变个位就可以。
说明 例词
规则变化 大多数序数词由“基数词+-th”构成 four—fourth
以y结尾的整十基数词变序数词，要变y为ie，再加“-th” thirty—thirtieth; fifty—fiftieth
20以上的非整十基数词变序数词，要将末尾数改成序数词，其他位数仍用基数词 thirty-one—thirty-first; one hundred and sixty-three—one hundred and sixty-third
不规则 变 化 少数序数词的构成属于特殊情况，需特别记忆 one—first; two—second; three—third; five—fifth; eight—eighth; nine—ninth; twelve—twelfth
（二）序数词的用法
1 序数词主要作定语、表语，前面要加定冠词the。
The fifth lesson is very easy to learn. 第五课很好学。
You are the first one I believe. 你是我最相信的人。
注意：1、序数词和冠词的连用
2. 序数词和定冠词连用表示顺序；和不定冠词连用，表示“又一，再一”，和零冠词连用时，表示名次，起副词的作用。
Our classroom is on the second floor of Building 2. 我们的教室在2号楼的2楼。
He failed twice, but he tried it a third time. 他失败了两次，但又尝试了一次。
Lily came second in the race. 莉莉在比赛中得了第二名。
3、表示分数词时，分子用基数词，分母用序数词；若分子大于1，表示分母的序数词要用复数形式。
Two fifths of the books are mine. 五分之二的书是我的。
4、“年、月、日”的表达法。
2014年7月22日 22nd July, 2014=July 22nd, 2014
5、数词前加every, 表达“每一段时间或每隔一段……”。
每隔10天/每隔8天 every ten days / every ninth day
每隔4周/每隔2周 every four weeks / every third week
