七、 數(shù) 詞
? (一) 知識(shí)概要
?數(shù)詞用來表示人或物的數(shù)目多少和順序。所以數(shù)詞主要有兩種：基數(shù)詞，用于計(jì)數(shù)，如：one, two而序數(shù)詞用于表示位置先后或次序，臺(tái)：first? second其構(gòu)成法如下：?

1 one first 1st
2 two second 2nd
3 three third 3rd
4 four fourth 4th
5 five fifth 5th
6 six sixth 6th
7 seven seventh 7th
8 eight eighth 8th
9 nine ninth 9th
10 ten tenth 10th

1000 a(one) thounsand thounsandth 1000th
10000 ten thounsand ten thounsandth 10000th
1000000 one million millionth 1000000th
基數(shù)詞與序數(shù)詞都有一定的構(gòu)成方法，但都有特殊例外的幾個(gè)字，所以除了要學(xué)會(huì)一般構(gòu)成法之外，還要特別記熟一些例外。因它們在考試中出現(xiàn)的頻率很高。
?1? 基數(shù)詞構(gòu)成結(jié)構(gòu)
?21～99的兩位數(shù)字，在10位和個(gè)位之間加連字符構(gòu)成，如89-eighty-nine.?１０１～９９９的三位數(shù)字，由hundred 加and 再加二位數(shù)或未位數(shù)字，如： 101-one hundred and one, 223-two hundred and twenty-three.?四位以上數(shù)字，應(yīng)從個(gè)位起向前數(shù)三位加逗號(hào)，讀作thousand,再數(shù)三位加第二個(gè)逗號(hào)，讀作million,再數(shù)三位加逗號(hào)，讀作billion，其讀法如下：
?1001-one thousand and one?５３８６-five thousand, three hundred and eighty－six?要注意的是hundred, thousand, million與billion的用法。①前面有別的基數(shù)詞時(shí)，即若干個(gè)百、千、百萬、十億時(shí)，其本身都不要加s，如：three hundred students。 ② 若表示成百，成千或數(shù)百，數(shù)千時(shí)，前面不能有基數(shù)詞，但其本身要用復(fù)數(shù)形式，然后+of+名詞復(fù)數(shù)。如：thousands and thousands of。 (成千上萬)
?2? 序數(shù)詞的構(gòu)成法
?序數(shù)詞除first, second, third 以外，其余一般在詞尾加th構(gòu)成，除一般略有差異的各別數(shù)詞外，很容易掌握。其二位數(shù)或多位數(shù)只將后面的個(gè)位數(shù)字改為序數(shù)詞，其前面各位數(shù)字均不改變，都用基數(shù)詞。
?3? 其他數(shù)字表示法
?小數(shù)的小數(shù)點(diǎn)讀作point，零讀作o［?ｕ］或zero,小數(shù)點(diǎn)后面的數(shù)字按個(gè)位基數(shù)詞依次讀出。?分?jǐn)?shù)分子用基數(shù)詞，分母用序數(shù)詞，當(dāng)分子大于1時(shí)，分?jǐn)?shù)要在序數(shù)詞上加s，但１／２用one half, 1 4 用a quarter. １ ３ 讀作one third而 ２ ３ 讀作two thirds。?百分?jǐn)?shù)(%)，讀作per cent (percent),但不論是多少均用作單數(shù)形式不能加s。?表示日期有兩種說法和四種寫法，如：2月1號(hào)英語表達(dá)法為：the first of February而美語為February (the) first,但其書寫上可有四種寫法① February 1 ② February 1st ③ 1st February ④ 1/2。?倍數(shù)的講法有所不同。兩倍用twice,而三倍以上用序數(shù)詞加times,如：He has three times as many books as I have.
? (二) 正誤辨析
? ［誤］ 1107 should be read as a thousand a hundred as seven.
? ［正］ 1107 should be read as one thousand one hundred and seven.
? ［析］ 在讀數(shù)字時(shí)，如：and前只有百或千時(shí)，用one hundred/ one thousand 還是a hundred /a thousand全是可以的。但如果文有百又有千時(shí)，則只能用one不要用a。 如果沒有and時(shí)，如：1100也只能讀作one thousand one hundred 或eleven hundred.
? ［誤］ I drove about half mile.
? ［正］ I drove about half a mile.
? ［析］ 半小時(shí)為half an hour, 半天為half a day, 半鎊為half a pound, 盡量避免用half a year, half a month, 要用six months, two weeks 或 fifteen days 要注意的是Half of the work is done? Half of the books are sold. 當(dāng)Half 作名詞時(shí)，其謂語動(dòng)詞要看of后面的名詞而定。如名詞是不可數(shù)名詞則用單數(shù)謂語動(dòng)詞，如是復(fù)數(shù)名詞時(shí)，則要用復(fù)數(shù)謂語動(dòng)詞。要注意的是一個(gè)半的表達(dá)法，如：One and a half apples is left on the table.其名詞要用復(fù)數(shù)，但謂語動(dòng)詞則要用單數(shù)。
? ［誤］ 60 students are playing on the ground.
? ［正］ Sixty students are playing on the ground.
? ［析］ 在句首的數(shù)字要用文字而不要用阿拉伯?dāng)?shù)字，如數(shù)字過大則應(yīng)放于句中，用阿拉伯?dāng)?shù)字。如： There are 166 students playing on the ground.
? ［誤］ He became famous around fifty years old.
? ［正］ He became famous in his fifties.
? ［析］ in his fifties 50多歲時(shí)，而in the fiflies 在50年代。
? ［誤］ There are about two thousands workers in our factory.
? ［正］ There are about two thousand workers in our factory?
? ［析］ 幾千，幾百的表達(dá)法是基數(shù)詞加thousand或加hundred,而且均不要加s。這樣的單位還有dozen(打)， score (20年)等。
? ［誤］ In the morning there are hundred of old people walking in the park.
? ［正］ In the morning there are hundreds of old people walking in the park.
? ［析］ 當(dāng)表達(dá)數(shù)百，數(shù)千時(shí)，要用hundreds of和thousands of 這一結(jié)構(gòu)。
? ［誤］ The class begins at eight a. m.
? ［正］ The class begins at 8 a. m.
? ［析］ 與符號(hào)或與縮寫的字母連用時(shí)一定要用數(shù)字，如：43%， 67?, No.2
? ［誤］ Two?fifth of the books are sold out.
? ［正］ Two?fifths of the books are sold out.
? ［析］ 分?jǐn)?shù)表示法，分子用基數(shù)詞，分母用序數(shù)詞，但分子大于1時(shí)，分母要在序數(shù)詞后?加s。
? ［誤］ Tom was born on July eighteen.
? ［正］ Tom was born on July eighteenth.
? ［析］ 月日的表達(dá)法有美語和英語兩種。? 美語 July 18 讀作 July eighteenth? 英語 July 18th 讀作 July the eighteenth
? ［誤］ I'll go to school at 7∶３０ a. m. in the morning.
? ［正］ I'll go to school at 7∶３０ a. m/ at 7∶３０ in the morning.
? ［析］ a. m 即表達(dá)在早上之意，不要再用in the morning.
? ［誤］ The film will begin at three quarters past one.
? ［正］ The film will begin at one quarter to two.
? ［析］ 大于30分鐘時(shí)不要使用past，而要用差多少不到幾點(diǎn)的to來表達(dá)。
? ［誤］ Three time three is nine.
? ［正］ Three times three is nine.
? ［析］ times 此處作為乘講一定要加s。 ?英語中乘除法表達(dá)式如下：
