      英語數字表示方法

        在漢英筆譯和英語寫作中,經常會遇到數字;哪些場合用單詞表示,哪些場合用阿拉伯數字表示,往往使人難以確定,現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字表達方法的內容,希望大家喜歡!

        英語中純數字的表達方法

        小數和分數:

        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

        英語中一千以上數字的表達方法是以三位數為單元,從高到低billion,million,thousand而依次讀出的。因此我們在聽時,可以三位數三位數地記錄。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以上的數目用阿拉伯數字(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)大數目用阿技伯數字表示顯得更簡潔明了,但不定數量、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、帶單位的特殊數字,通常用阿拉伯數字。如:

        Maximum swivel of table is l20.

        工作臺的最大回轉角度是120度。

        又如:

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

       ?、趐urchased 7 yards of carpet(買7碼地毯);

        ③ordered 2 pounds of minced steak (訂購2磅剁碎的肉)。

        如果涉及的數目和單位是不定數,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(我已經警告你多少遍了)。

        (4)在科技文章中,數字頻繁出現,用阿拉伯數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,轉速為每分鐘4400轉時輸出功率是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)句首不用阿拉伯數字,句末要盡量避免用阿拉伯數字,

        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,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。
