We use Cardinal numbers everyday.
Presentatin
表示数目的词称为基数词(Cardinal numbers)。其形式如下：
1－12, 独立成词。ne tw three fur five six seven eight nine ten eleven twelve
20－90, 以-ty结尾。20—twenty 30－thirty 40—frty 50—fifty 80—eighty 60—sixty 70—seventy 90—ninety
13－19, 由3－9 + teen构成。14–furteen 16－sixteen 17－seventeen 19—nineteen 特殊拼写: 13— thirteen 15—fifteen 18—eighteen
21－99， 两位数，十位与个位之间有 “－”。twenty-ne 55 fifty-five 99 ninety-nine
101—999，三位数，百位与十位/个位之间加and。101 ne hundred and ne840 eight hundred and frty693 six hundred and ninety-three
英语数词不难记，找出规则就容易。 　　零至十二形各异，一个一个单独记。 　　后面加teen变十几，thirteen, fifteen看仔细。 　　eighteen只有一个t，两个音节念清晰。 　　　表示“几十”要加-ty, twenty, thirty 是特例。表示数字“几十几”，连字符号别忘记。
1，000以上数目,从右向左每三位用“，”分开,分别读为thusand , millin, billin
4,056= 23,813= 567,110=6,425,200=
fur thusand and fifty-six

5. Tw millin three hundred and tw
6. nine hundred millin eight thusand seven hundred and eight
After the war, thusands f peple became hmeless.Several / Many thusands f trees must be planted every year.
表示不确定数目,用复数。即hundreds f(数百),thusands f(数千), millins f(数百万)+ 名词复数,可以用many/several修饰，但不能与具体数目连用。
“基数词+名词” 的合成形容词作定语，中间有连字符“－”,当中的名词用单数。
表计量: 基数词+度量单位+形容词
a 3 – year – ld girl a seven-day hliday
The classrm is 7 meters lng, 6 meters wide and 3 meters high.
基数词
We use rdinal numbs t rder things and events.We use them t talk abut dates,flrs,psitins,etc.
1－3, first, secnd, third 。4－19, 相应基数词+ th, 特殊拼写:fifth, eighth, ninth, twelfth。 20－90, y变成ie +th,如twentieth。 21－99, 只把个位的基数词变成序数词 如twenty-first。 序数词缩写：数字＋最后两字母 如1st, 2nd, 3rd ,4th…
基变序,有规律,一、二、三，特殊记，面目全非要注意，加th从4起，八少“t”，九去“e”，“ve”要用“f”替，(five, twelve)见“y”变成“i”和“e”，词尾加上“th”，(twenty, thirty,……ninety)若是遇到几十几，只变个位就可以。序数词缩写记清楚,数字后跟两字母。
(1)序数词作定语，前面要加the； The first truck is carrying a fd basket． Jhn lives n the fifteenth flr． She is my first English teacher.
有时加a/an，“再一”，“又一” 的意思We’ll have t d it a secnd time． Shall I ask him a third time？ When I sat dwn, a furth man rse t speak．They had a secnd child in 1988
编号在前，名词在后，用序数词，前面有the。编号在后，名词在前，用基数词，注意首字母大写。房间号码和电话号码要一个一个分别读

[解题技巧] 以此立意的试题要求考生能正确使用基数词和序数词：基数词用来表达事物的量；序数词用来表达事物的顺序。本题的第一空表示顺序用序数词secnd；第二空用基数词three，答案为B。
2.Hw many peple will cme t Beijing next year?It’s hard t say, ________ peple, I think.（2017年仁寿县模拟）A. millin f B. millins f C. three millins D. three millins f
[解题技巧]以此立意的试题考查考生能否正确使用hundred等单位数词。表示单位的数词用法分两种情况：1.当放在具体的数字后边，表示具体的“百、千、百万、十亿”时，不能用复数形式，可以直接修饰名词复数，如tw thusand students；2.当表示大概的“几百、几千、几百万、几十亿”时，用“复数形式＋f”结构，前边不能用具体的数字，如：thusands f students。本题中只有B项正确。
