英语倍数表示法
资料一
关于英语倍数表示法的文章很多,而且列举了一大堆的句型,让人看了眼花缭乱。在仔细地分析了各种句式后,实际上,英语倍数最大的特点是:先说“倍数”,再说“是谁的……”,“比谁的……”等。概括起来,英语倍数表示主要就三种句式。
1、倍数+比较级...(1)倍数 as...as(意思是“A是B的几倍”。)I am twice as old as he.我的年纪是他的两倍。
He earns twice as much as he used to.他比往常多赚二倍的钱。
An ordinary subway train, approaching the station, can be twice as loud as the loudest jet.发出的声音可能是喷射机的两倍。
She studies three times as hard as I.她用功的程度是我的三倍。
This line is four times as long as that one.这条线是那条线的四倍长。
We've produced twice as much cotton this year as ten years ago.今年的棉花比十年前多了一倍。
He has got three times as many books as his sister.他拥有的书的数量是他妹妹的三 倍。
在比较级前,还可以用over,more thant 等表示“比……倍还要多”。例如: He is more than three times as rich as I.他的财富是我的三倍还不止。I am more than twice as old as he.我的年龄是他的两倍还不止。
He studies more than three times as hard as I.他用功的程度是我的三倍还不止。He has collected more than three times as many stamps as I.他搜集的邮票是我的三倍还不止。
(2)倍数+比较级(意思是:A是B的几倍)Line A is four times the length of line B.线条 A 是线条 B 的四倍长。I have five times the number of Tom’s books.我有五倍于汤姆的书。He has three times my money.他的钱是我的三倍。
The river is ten times the length of the Tamsui River.这条河的长度是淡水河的十倍。This street is four times shorter than that one.这条街道比那条短四倍。

It is ten times louder than another.它比另外一个的声音大十倍。
This street is three times wider than that one.这条街比那条街宽三倍。I am twice older than he.我的年纪比他大两倍。使用more...than 比较级的例句:
He earns five times more money than he did ten years ago.他现在挣的钱比十年前挣的多 5 倍。
There are twice more students in our cla than in theirs.我们班的学生人数比他们班多两倍。
比较级也可使用分数、小数等数字。例如:
The box is one-third bigger than that one.这个盒子比那个盒子大三分之一。Last year the output value of industry was 59 percent higher than that of 1976.去年工业产值比 1976 年增长了 59 %。My command of English is not half so good as yours.我英语掌握得还不及你的一半儿好。
在比较级前,还可以用over,more thant 等表示“比……倍还要多”。例如:
It was over twice the distance of the earth from the sun.那是地球到太阳的距离的两倍多。
He has more than three times my money.他的钱是我的三倍还不止。
2、倍数+the 度量词 of...The earth is 49 times the size of the moon.地球的体积是月球的 49 倍。This river is three times the depth of that one.这条河深度是那条河的三倍。下边也可看作是这种句式的变化:
The length of the road is four times what it was three years ago.这条路的长度是三年前的 4 倍。
The price of the meat is twice what it was last year.肉价是去年的两倍。
The size of the sun is a million times over that of the earth.太阳的体积比地球的体积大一百万倍。
He is three times up on your age.他的年龄是你的 4 倍(或:比你的年龄大 3 倍)In this workshop the output of July was 3.5 times that of January.七月份的产量是元月份的 3.5 倍
3、其它表示法
(1)英语中有些词表示特定的倍数,例如: again(一倍), twice, double(两倍), triple(三倍), fourfold(四倍)等数。
My Aunt is as old again as I am.我姑姑的年龄比我大一倍。

Compared with last year,our coal output has increased by three times.与去年相比,我们的煤产量增长了 3 倍。(使用by...)His speed is faster than mine by four times.他的速度比我的快 4 倍。
The number of the students in our school has increased four times compared with 1980.我们学校的学生人数比 1980 年增加了 3 倍。(使用 compared with)The production of integrated circuits has been increased to three times as compared with last year.集成电路的产量比去年增加了两倍。
The principal advantage of the products is a two-fold reduction in weight.这些产品的主要优点是重量减轻了1/2。

资料二
1.A是B的N倍大/长…(或者A比B大/长…N-1倍)一般有以下两种英语表达方法;(1)A is N times as large/long(形容词/副词原形)as B.Eg: Asia is four times as large as Europe.(2)A is N times larger/longer(形容词/副词比较级)than B.Eg: Asia is four times larger than Europe.(3)A is N times the size/length(形容词/副词的名词形式)of B.Eg: Asia is four times the size of Europe.以上三句例句的中文翻译均为:亚洲是欧洲的四倍大,或者亚洲比欧洲大三倍。
PS:全国的老师都欺骗了我们啊!说实话,看到Asia is four times larger than Europe.第一个反应是亚洲比欧洲大四倍,有木有?可这个翻译是错的!来自五湖四海的英语小编们个个跳出来指认,从小到大,老师都是这么教的,考试也是这么考的,怎么会错呢?于是,遍查资料后发现,全国的老师好像都错了......还是不死心,这要是错了,简直是推翻了我们从小到大的人生观啊。抱着最后一丝希望,请教了外教,于是,人生观无情地被颠覆了。所以,全国的同学们,请大家从此牢记:A is N times larger/longer than B的这个用法就是“A是B的N倍大/长,A比B大/长N-1倍”!切记,切记啊!2.by 和to(1)动词+ by + 倍数/百分数/数词
Eg: The production of grain has been increased by four times this year.今年粮食产量增加了四倍。(2)动词+ to + 数词
Eg: Last year profits rose to $201 million.去年利润增长到2亿零100万美元。3.by a factor of 词组by a factor of 在《朗文双解》中的解释为“if something increases or decreases by a factor of N, it increases or decreases by N times.”以N倍的系数增加或减少。这个解释表达不是很明确,现在把它分成以下两种情况来分析:(1)表示增加含义时
Increase/grow…by a factor of N times 增加到N倍,或者增加了N-1倍
Eg: The output of diesel oil for farm use has been increased by a factor of five times these years.这些年来,用于农业生产的柴油产量增加了四倍。(2)表示减少含义时
Decrease/fall…by a factor of N times 减少到1/N,或者减少了(N-1)/N。Eg: The production has decreased by a factor of three times as against 1977.总产量减少到1977年的三分之一。
结语:倍数翻译的陷阱很多吧,而且每个陷阱都是绵里藏针,针针见血,见血封喉!要想在倍数翻译上不出错,除了基本的语法过关外,还要仔细检查,认真思考,一点点小小的差异都有可能造成误译、错译。所以,让我们一起认真学习钻研数字翻译、倍数翻译的方法,攻克重重堡垒,到达胜利彼岸!

表示倍数减少的翻译方法
英语中表示倍数减少的表达方法
(一)a is n times as small(light,slow,…)as b.a is n times smaller(lighter,slower,…)than b.以上两句均应译为:a的大小(重量,速度,……)是b的1/n[或a比b小(轻,慢,……)(n-1)/n].e.g.The hydrogen atom is near1y l6 times as light as the oxygen atom.氢原子的重量约为氧原子的1/16(即比氧原子约轻15/16)。
e.g.This sort of membrane is twice thinner than ordinary paper.这种薄膜比普通纸张要薄一半(即是普通纸厚度的1/2)。
注:当相比的对象b很明显时,than/as b常被省去。
(二)decrease n times/n——fold
decrease by n times
decrease by a factor of n
以上三式均译为:减少到1/n[或:减少(n-1)/n].decrease常被reduce,shorten,go/slow down等词替代。
e.g.Switching time of the new-type transistor is shortened 3 times.新型晶体管的开关时间缩短了1/3(即缩短到2/3)。
e.g.When the voltage is stepped up by ten times,the strength of the current is stepped down by ten times.电压升高9倍,电流强度便降低9/10(即90%)。
e.g.The equipment reduced the error probability by a factor of 5.该设备误差概率降低了4/5.(三)there is a n-fold decrease/reduction… 应译为:减至1/n [或:减少(n一1)/n].这个句型还有其它一些形式,e.g.A rapid decrease by a factor of 7 was observed.发现迅速减少到1/7.e.g.The principal advantage of the products is a two-fold reduction in weight.这些产品的主要优点是重量减轻了1/2.英语在表述或比较倍数时,无论使用什么句型(除了不含倍数词的again句型外)都包括基础倍数在内,因此都不是净增或净减n倍,而是净增或净减n-1倍。
