We use Cardinal numbers everyday.
Presentatin
表示數(shù)目的詞稱為基數(shù)詞(Cardinal numbers)。其形式如下：
1－12, 獨(dú)立成詞。ne tw three fur five six seven eight nine ten eleven twelve
20－90, 以-ty結(jié)尾。20—twenty 30－thirty 40—frty 50—fifty 80—eighty 60—sixty 70—seventy 90—ninety
13－19, 由3－9 + teen構(gòu)成。14–furteen 16－sixteen 17－seventeen 19—nineteen 特殊拼寫(xiě): 13— thirteen 15—fifteen 18—eighteen
21－99， 兩位數(shù)，十位與個(gè)位之間有 “－”。twenty-ne 55 fifty-five 99 ninety-nine
101—999，三位數(shù)，百位與十位/個(gè)位之間加and。101 ne hundred and ne840 eight hundred and frty693 six hundred and ninety-three
英語(yǔ)數(shù)詞不難記，找出規(guī)則就容易。 　　零至十二形各異，一個(gè)一個(gè)單獨(dú)記。 　　后面加teen變十幾，thirteen, fifteen看仔細(xì)。 　　eighteen只有一個(gè)t，兩個(gè)音節(jié)念清晰。 　　　表示“幾十”要加-ty, twenty, thirty 是特例。表示數(shù)字“幾十幾”，連字符號(hào)別忘記。
1，000以上數(shù)目,從右向左每三位用“，”分開(kāi),分別讀為thusand , millin, billin
4,056= 23,813= 567,110=6,425,200=

6. nine hundred millin eight thusand seven hundred and eight

表示不確定數(shù)目,用復(fù)數(shù)。即hundreds f(數(shù)百),thusands f(數(shù)千), millins f(數(shù)百萬(wàn))+ 名詞復(fù)數(shù),可以用many/several修飾，但不能與具體數(shù)目連用。
“基數(shù)詞+名詞” 的合成形容詞作定語(yǔ)，中間有連字符“－”,當(dāng)中的名詞用單數(shù)。
表計(jì)量: 基數(shù)詞+度量單位+形容詞
a 3 – year – ld girl a seven-day hliday
The classrm is 7 meters lng, 6 meters wide and 3 meters high.
基數(shù)詞
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, 相應(yīng)基數(shù)詞+ th, 特殊拼寫(xiě):fifth, eighth, ninth, twelfth。 20－90, y變成ie +th,如twentieth。 21－99, 只把個(gè)位的基數(shù)詞變成序數(shù)詞 如twenty-first。 序數(shù)詞縮寫(xiě)：數(shù)字＋最后兩字母 如1st, 2nd, 3rd ,4th…
基變序,有規(guī)律,一、二、三，特殊記，面目全非要注意，加th從4起，八少“t”，九去“e”，“ve”要用“f”替，(five, twelve)見(jiàn)“y”變成“i”和“e”，詞尾加上“th”，(twenty, thirty,……ninety)若是遇到幾十幾，只變個(gè)位就可以。序數(shù)詞縮寫(xiě)記清楚,數(shù)字后跟兩字母。
(1)序數(shù)詞作定語(yǔ)，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.
有時(shí)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
編號(hào)在前，名詞在后，用序數(shù)詞，前面有the。編號(hào)在后，名詞在前，用基數(shù)詞，注意首字母大寫(xiě)。房間號(hào)碼和電話號(hào)碼要一個(gè)一個(gè)分別讀

[解題技巧] 以此立意的試題要求考生能正確使用基數(shù)詞和序數(shù)詞：基數(shù)詞用來(lái)表達(dá)事物的量；序數(shù)詞用來(lái)表達(dá)事物的順序。本題的第一空表示順序用序數(shù)詞secnd；第二空用基數(shù)詞three，答案為B。

[解題技巧]以此立意的試題考查考生能否正確使用hundred等單位數(shù)詞。表示單位的數(shù)詞用法分兩種情況：1.當(dāng)放在具體的數(shù)字后邊，表示具體的“百、千、百萬(wàn)、十億”時(shí)，不能用復(fù)數(shù)形式，可以直接修飾名詞復(fù)數(shù)，如tw thusand students；2.當(dāng)表示大概的“幾百、幾千、幾百萬(wàn)、幾十億”時(shí)，用“復(fù)數(shù)形式＋f”結(jié)構(gòu)，前邊不能用具體的數(shù)字，如：thusands f students。本題中只有B項(xiàng)正確。
