英語數(shù)字表示方法

  在漢英筆譯和英語寫作中,經(jīng)常會遇到數(shù)字;哪些場合用單詞表示,哪些場合用阿拉伯數(shù)字表示,往往使人難以確定,現(xiàn)行語法書中也極少涉及此類問題。下面由學習啦小編為大家整理的關于英語數(shù)字表達方法的內(nèi)容,希望大家喜歡!

  英語中純數(shù)字的表達方法

  小數(shù)和分數(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

  大于100的數(shù)字:

  101 one hundred (and ) one

  200 two hundred

  998 nine hundred ( and ) ninety'eight

  在英語中上面括弧中的and一般不能省略;而在美國英語中卻往往省去。請分析下面的對話:

  A:How many people are present in the party last night?

  B: That‘s nine hundred and ninety-eight, exactly.

  A: Woo, you must be joking. How can you get such an accurate number?

  B: Ha, ha…… surely I am joking. You silly goose.

  大于1000的數(shù)字:

  1001 a/one thousand (and) one

  2232 two thousand two hundred (and) thirty'two

  900,732,266,043

  nine hundred billion seven hundred thirty'two million two hundred sixty'six thousand and forty three

  英語中一千以上數(shù)字的表達方法是以三位數(shù)為單元,從高到低billion,million,thousand而依次讀出的。因此我們在聽時,可以三位數(shù)三位數(shù)地記錄。試比較下面的對話:

  A:Can you tell me exactly the numbers of the whole people in our country?

  B:One billion four hundred thirty'two million two hundred sixty'six thousand and forty three.

  A:Thank you very much.

  用英語表達數(shù)字的規(guī)則

  1)英美等國的出版社在排版時遵循一條原則,即1至10用單詞表示,10以上的數(shù)目用阿拉伯數(shù)字(也有的以100為界限),這條原則值得我們行文時借鑒。如:

  That table measures ten feet by five.

  那個工作臺長10英尺,寬5英尺。

  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.

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

  (2)大數(shù)目用阿技伯數(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。如:

  There are 203817 voters on the electoral rolls。

  選舉名單上有203817個投票人。

  Nearly thirty thousand voters took part in this election.

  近3萬個投票人參加了這次選舉。

  (3)遇到日期、百分比、帶單位的特殊數(shù)字,通常用阿拉伯數(shù)字。如:

  Maximum swivel of table is l20.

  工作臺的最大回轉(zhuǎn)角度是120度。

  又如:

 ?、?rd march l991或3 march l991; a discount of 5 percent(5%的折扣);

  ②purchased 7 yards of carpet(買7碼地毯);

 ?、踥rdered 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,

  如:① about five miles per hour(每小時大約5英里),

 ?、赼t least ten yards away(至少有10碼遠),

 ?、踙esitated for a moment or two(猶豫了片刻),

 ?、躨 have warned you a hundred times(我已經(jīng)警告你多少遍了)。

  (4)在科技文章中,數(shù)字頻繁出現(xiàn),用阿拉伯數(shù)字比用單詞陳述更有利,如:

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

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

  we know that the weight of a cubic foot of air at 0℃,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。

  (5)句首不用阿拉伯數(shù)字,句末要盡量避免用阿拉伯數(shù)字,

  4th July is an important date in American history.

  應該寫成the fourth of July...

  19 couples took part in the ballroom dancing competition.

  19對選手參加了交際舞比賽。應改寫成:Nineteen couples took…

  60% profit was a reported.據(jù)報道有60%的利潤。

  應改寫成:Sixty per cent profit…

  1345 kilograms force was applied at the center point of the bar.

  試驗時在桿的中點加1345公斤力。

  可改成When tested, a force of l345 kg was applied…

  (6)遇到分數(shù),可用帶連字符號的單詞表示,如:

  At 1east two-thirds of the class have had colds. 這個班至少有三分之二的學生患重感冒。

  Nitrogen forms about four-fifths of the atmosphere. 氮約占大氣的五分之四。
