专四语法四:英语倍数表达法及译法
(三)There is a n-fold increase/growth… 应译为:增加n-倍(或增至n倍)。这个句型还有其它一些形式: Eg. A record high increase in value of four times was reported. 据报道,价值破记录地增长了3倍。 (四)double (增加1倍),treble(增加2倍),quadruple(增加3 倍)。 Eg. The efficiency of the machines has been more than trebled or quadrupled. 这些机器的效率已提高了2倍或3倍多。 (五)此外,英语中还有一种用again而不用倍数词来比较倍数的方 法,如: A is as much (large,long,…)again as B.(= A is twice as much (large,long,…)as B. 应译为:A比B多(大,长,……)1倍。 A is half as much (large, 1ong,…)again as B. 【= A is one and a half times as much (large, 1ong,…)as B.】 应译为:A比B多(大,长……)一半(即A是B的一倍半)。
倍数减少
(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]。 Eg. 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)。 Eg. 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。

7. If the resistance is doubled without changing the voltage ,the current becomes only half strong. 8. By the end of 2007 , the number of mobile phone users in China has trebled that in 2003. 9. Efforts will be made to quadruple the GDP of the year 2000 by 2020.

注:在这类句型中increase常被raise, grow,go/step up,multiply等词 所替代。
Increase by 句型翻译的证据 这一结构产生误解 的概率很高 往往误 译成 比以前增加 倍 其实 它和 increase N times 和increase to N times 表达的倍数概念相同,应译为 增加N-1 倍。
另外, 还要注意的是, 表示“增加”用times 或- 。 fold 与用百分数或具体数值是有所不同的, 增 加的数 值或百分数均表示净增量, 例如: Population has increased by 200 %in the past 25 years. 人口在过去 25 年内增加了 200 % (即增加两 倍) 。 its output of cotton went up by 20 percent. 它的棉花产量增长了20 % 。
