定義:表示數(shù)目多少或順序先后的詞叫做數(shù)詞。數(shù)詞有兩種:表示數(shù)目多少的數(shù)詞叫做基數(shù)詞,如:ne,tw,three...,ninety-fur等;表示順序先后的數(shù)詞叫做序數(shù)詞,如:first,secnd,third...,fifteenth等。There are five peple in my family. We live n the sixth flr in a tall building.我家有五口人。我們住在一座高樓的第六層。
基數(shù)詞(一)基數(shù)詞的表示方法1.基數(shù)詞1~12是獨(dú)立的詞,13~19都是以teen結(jié)尾的詞。
(1)1~12要逐個(gè)記:1 ne /w?n/ 2 tw /tu?/3 three /θri?/ 4 fur /f??/5 five /faIv/ 6 six /sIks/7 seven / ' sevn/ 8 eight /eIt/9 nine /naIn/ 10 ten /ten/11 eleven /I ' levn/ 12 twelve /twelv/
(2)13~19都以teen結(jié)尾,都是雙重音:13 thirteen /,θ?? ' ti?n/ 14 furteen /,f??' ti?n/15 fifteen /,fif' ti?n/ 16 sixteen /,siks' ti?n/17 seventeen /,sevn' ti?n/ 18 eighteen /,eI' ti?n/19 nineteen /,naIn' ti?n/
2.基數(shù)詞20~90整十位數(shù)都是以ty結(jié)尾。
20 twenty / ' twentI/ 30 thirty / ' θ??tI/40 frty / ' f??tI/ 50 fifty / ' fIftI/60 sixty / ' sIkstI/ 70 seventy / ' sevntI/80 eighty / ' eItI/ 90 ninety / ' naIntI/
注:13~19的teen/'ti?n/都是重讀音,而20~90的ty/tI/都是非重讀音節(jié);/'ti?n/為長(zhǎng)音,而/tI/為短音。
3.基數(shù)詞21~99都是由“幾十”和“幾”合起來(lái)構(gòu)成,詞中間加連字符(但音標(biāo)里不加連字符),并分別重讀。21 twenty-ne /,twentI'w?n/23 twenty-three /,twentI'θri?/34 thirty-fur /,θ??tI'f??/45 frty-five /,f??tI'faIv/56 fifty-six /,fIftI'sIks/67 sixty-seven /,sIkstI'sevn/
4.基數(shù)詞101~999,先說(shuō)“幾百”,再加“and”,再加末兩位數(shù)?!狧w many days are there in a year? 一年有多少天?—_________________________. 三百六十五天.
5.1,000以上的數(shù),先從后向前數(shù),每三位加“,”,第一個(gè)“,”前為thusand,第二個(gè)“,”前為millin,第三個(gè)“,”前為billin(美式)或thusand millin(英式)。—Can yu write the number _______________________________________?你會(huì)寫(xiě)數(shù)字85,626嗎?—Yes, it is 85,626. 會(huì)寫(xiě),它是85,626。
Three hundred and sixty-five
eighty-five thusand,six hundred and twenty-six
6.百(hundred),千(thusand),百萬(wàn)(millin)等詞與數(shù)字或a(n)連用時(shí),詞尾不可加“s”。The cmputer was cheap. ______________________________________那臺(tái)電腦很便宜,我只花了兩千元.
7.百(hundred),千(thusand),百萬(wàn)(millin)等詞與介詞f連用時(shí),須用復(fù)數(shù)形式,表示不確定數(shù)目,其前不可與數(shù)字連用。—Hw many peple went t Beijing fr the Olympic Games in 2008?有多少人去北京看2008年奧運(yùn)會(huì)?—_______________,I think. 上百萬(wàn),我認(rèn)為。
I spent nly tw thusand yuan n it.
8.表示“幾十”的數(shù)詞的復(fù)數(shù)形式可用來(lái)表示人的歲數(shù),在表示“幾十年代”時(shí),可以用基數(shù)詞的復(fù)數(shù)形式,也可用阿拉伯?dāng)?shù)字加“s”或“'s”。She is ________________ but she lks yung.她五十多歲,但她看上去很年輕。Frm_______________ t _______________,picture-stry cartns were very ppular.從20世紀(jì)50年代到20世紀(jì)70年代,圖畫(huà)故事的卡通片是很受歡迎的。

9.基數(shù)詞可與其他詞構(gòu)成合成形容詞。Kate is an __________________ girl. 凱特是個(gè)18歲的女孩。10.基數(shù)詞可用作主語(yǔ)、賓語(yǔ)、表語(yǔ)或同位語(yǔ)。Give him three.(賓語(yǔ)) 給他三個(gè)。___________ f the teachers in ur schl are wmen teachers.(主語(yǔ))我們學(xué)校三分之二的老師是女老師。
eighteen的讀音以元音開(kāi)頭,故其前要用不定冠詞an。注:這種合成形容詞的結(jié)構(gòu)為:“數(shù)詞+單數(shù)名詞+形容詞”。復(fù)合形容詞中,詞與詞之間要加連字符“-”。
eighteen-year-ld
11.電話號(hào)碼的讀法為順次讀出一個(gè)個(gè)數(shù)字,“0”讀作“”或“zer”。數(shù)字連續(xù)重現(xiàn)時(shí)可用“duble(雙)”。62884405讀作__________________________________或_________________________________________。

2.序數(shù)詞作主語(yǔ)、賓語(yǔ)、表語(yǔ)、定語(yǔ)、同位語(yǔ)或狀語(yǔ)。She was the_fifth in the exam.(作表語(yǔ))The first f June is Children's Day.(主語(yǔ))3.表順序時(shí),基數(shù)詞和序數(shù)詞可互換,如:Lessn Five=____________________
