在平时办公过程当中,经常会遇到数字。哪些场合用单词表示,哪些场合用阿拉伯数字表示,往往使人难以确定。现行语法书中也极少涉及此类问题。实际上,以英语为母语的国家,在书写数字时已形成几条约定俗成的规则,总结如下,以供大家参考。 一、英美等国的出版社在排版时遵循一条原则,即1至10用单词表示,10以上的数目用阿拉伯数字(也有的以100为界限)表示。 Eg. That table measures ten feet by five. Eg. Traditionally classes at college level bring the professor and a group of 20 to 30 students together for a 45-to-50-minute class two or three times a week. 二、人数用阿拉伯数字表示显得更简洁明了,但不定数量、近似值用单词表示较恰当。 Eg. There are 203817 voters on the electoral rolls. Eg. Nearly thirty thousand voters took part in this election. Eg. I hesitated for a moment or two. Eg. I have warned you a hundred times. 三、遇到日期、百分比、带单位的特殊数字,通常用阿拉伯数字。 Eg. The maximum swivel of the table is l20. Eg. 3rd March l991或3 March l991; a discount of 5 per cent Eg. I purchased 7 yards of carpet Eg. I ordered 2 pounds of minced1 steak 五、在科技文章中,数字频繁出现,用阿拉伯数字比用单词陈述更有利。 Eg. The new engine has a 4.3L capacity and a power output of 153 kilowatts2 at 4400 revolutions per minute. 六、句首不用阿拉伯数字,句末也要尽量避免用阿拉伯数字。 Eg. 4th July is an important date in American history. Eg. A 60%profit was reported. 七、遇到分数,可用带连字符号的单词表示。 Eg. At least two-thirds of the class have bad colds. Eg. Nitrogen forms about four-fifths of the atmosphere. 点击收听单词发音
