開封翻譯公司告訴你英文數(shù)字表達(dá)方式


  EXPRESSION OF NUMBER / FIGURE IN ENGLISH
TABLE OF CONTENYS

  一、小數(shù)、百分?jǐn)?shù)

  二、 阿拉伯?dāng)?shù)字與單詞數(shù)字

  三、數(shù)詞(主要分為基數(shù)詞和序數(shù)詞兩類)

  四、分?jǐn)?shù)

  五、數(shù)量表示法

  六、英語中時(shí)間的表達(dá)方法

  七、年月表示法

  八、加減乘除表示法

  一、小數(shù)

  0.17 zero point one seven / point seventeen / zero point seventeen

  1/2 one half  1/3 one /a third  3/4 three fourths

  7'2/ 5seven and two fifths

  1. 小數(shù)用基數(shù)詞來表示,以小數(shù)點(diǎn)為界,小數(shù)點(diǎn)左首的數(shù)字為一個(gè)單位,表示整數(shù),數(shù)字合起來讀;小數(shù)點(diǎn)右首的數(shù)字為一個(gè)單位,表示小數(shù),數(shù)字分開來讀;小數(shù)點(diǎn)讀作 point,o讀作 zero或o[ou],整數(shù)部分為零時(shí),可以省略不讀。

  0.4 zero point four或point four 零點(diǎn)四

  10.23 ten point two three 十點(diǎn)二三

  25.67 twenty-five point six seven 二十五點(diǎn)六七

  l.03 one point o three 一點(diǎn)零三

  2. 當(dāng)數(shù)字值大于1時(shí),小數(shù)后面的名詞用復(fù)數(shù),數(shù)字值小于1時(shí),小數(shù)后面的名詞用單數(shù)。

  1.03 meters 一點(diǎn)零三米 0.49 ton 零點(diǎn)四九噸

  l.5 tons 一點(diǎn)五噸

  百分?jǐn)?shù)用基數(shù)+percent表示

  50% fifty percent   百分之五十

  3% three percent   百分之三

  0.12% zero point one two percent 百分之零點(diǎn)一二

  這里的percent前半部per表示“每一”,cent這一后半部分表示“百”,所以百分之幾中percent不用復(fù)數(shù)形式。

  二、 阿拉伯?dāng)?shù)字與單詞數(shù)字

  (1)1至10用單詞表示,10以上的數(shù)目用阿拉伯?dāng)?shù)字(也有的以100為界限),這條原則值得我們行文時(shí)借鑒。

  例. That table measures ten feet by five.  那個(gè)工作臺長10英尺,寬5英尺。

  例. The traditional pattern of classroom experience at the college level brings the professor and a group of 20 to 30 students together for a 45-to-50-minute class session two or three times a week.

  由一個(gè)教授和十名學(xué)生每周會晤兩三次,每次授課時(shí)間45到50分鐘,是大學(xué)程度課堂教學(xué)的傳統(tǒng)方式。

  人數(shù)用阿技伯?dāng)?shù)字表示顯得更簡潔明了,但不定數(shù)量、近似值用單詞表示較恰當(dāng)。

  例. There are 203817 voters on the electoral rolls. 選舉名單上有203817個(gè)投票人。

  例. Nearly thirty thousand voters took part in this election. 近3萬個(gè)投票人參加了這次選舉。

  (2)句首不用阿拉伯?dāng)?shù)字,句末要盡量避免用阿拉伯?dāng)?shù)字。

  例. 4th July is an important date in American history. 應(yīng)該寫成The fourth of July...

  例. 19 couples took part in the ballroom dancing competition. 19對選手參加了交際舞比賽。

  應(yīng)改寫成:Nineteen couples took...

  例. 60%profit was a reported. 據(jù)報(bào)道有60%的利潤。 應(yīng)改寫成:Sixty per cent profit…

  例. 1345 kilograms force was applied at the center point of the bar. 試驗(yàn)時(shí)在桿的中點(diǎn)加1345公斤力。 可改成When tested, a force of l345 kg was applied...

  遇到日期、百分比、帶單位的特殊數(shù)字,通常用阿拉伯?dāng)?shù)字。

  例. Maximum swivel of table is l20.   工作臺的最大回轉(zhuǎn)角度是120度。

  例. 3rd March l991或3 March l991;  a discount of 5 percent(5%的折扣);

  例. purchased 7 yards of carpet(買7碼地毯);

  例. ordered 2 pounds of minced steak(訂購2磅剁碎的肉)。

  如果涉及的數(shù)目和單位是不定數(shù),可用單詞表示。

  例. about five miles per hour(每小時(shí)大約5英里)

  例. at least ten yards away(至少有10碼遠(yuǎn))

  例. hesitated for a moment or two(猶豫了片刻)

  例. I have warned you a hundred times(我已經(jīng)警告你多少遍了)。

  在合同技術(shù)附件中,數(shù)字頻繁出現(xiàn),用阿拉伯?dāng)?shù)字比用單詞陳述更有利。

  例. The new engine has a capacity of 4.3 litres and a power out-put of 153 kilowatts at 4400 revolutions per minute.

  這臺新發(fā)動機(jī)的容積為4.3升,轉(zhuǎn)速為每分鐘4400轉(zhuǎn)時(shí)輸出功率是153千瓦。

  例. We know that the weight of a cubic foot of air at 0oC and 76cm,pressure is 0.08l pound, or 12 cubic feet of air weigh a pound.

  我們知道,1立方英尺的空氣在0攝氏度和760毫米汞柱壓力下,重量是0.81磅,也就是說12立方英尺空氣的重量是1磅。

  大于100的數(shù)字:

  101 one hundred and one

  200 two hundred

  998 nine hundred and ninety eight

  E.千位數(shù)以上

  從數(shù)字的右端向左端數(shù)起,每三位數(shù)加一個(gè)逗號“,”。從右開始,第一個(gè)“,”前的數(shù)字后添加 thousand,第二個(gè)“,”前面的數(shù)字后添加 million,第三個(gè)“,”前的數(shù)字后添加 billion。然后一節(jié)一節(jié)分別表示,兩個(gè)逗號之間最大的數(shù)為百位數(shù)形式。

  2,648 two thousand six hundred and forty-eight

  F.基數(shù)詞在表示確切的數(shù)字時(shí),不能使用百、千、百萬、十億的復(fù)數(shù)形式;但是,當(dāng)基數(shù)詞表示不確切數(shù)字,如成百、成千上萬,三三兩兩時(shí),基數(shù)詞則以復(fù)數(shù)形式出現(xiàn)。
