(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。 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。

英语中如何表达倍数 Ting Bao was revised on January 6, 20021
英语中如何表达倍数 1. 倍数 + as + 形容词或副词的原级 + as + 其他。 这种结构又常演变成下列两类： ①倍数 + as + many + 可数名词复数 + as； ②倍数 + as +much + 不可数名词 + as。如： There are seven times as many people as I expected.是我预料的人数的七倍。 There is five times as much coffee in this glass as in that one. 这个杯子里的咖啡是那个杯子里的五倍。 2. 倍数 + 形容词（或副词）的比较级 + than + 其他。如： The hall is five times bigger than our classroom. 这个大厅的面积比我们教室大五倍。 3. 倍数 + the size / height / length / width. etc. + of + 其他。如： This road is six times the length of that one. 这条路是那条路的六倍长。 4. 计量名词 + of + 名词 + be +倍数 + that + of + 其他。如： The size of the newly broadened square is four times that of the previous one. 新扩建的广场为以前的四倍大。 5. 倍数+what从句。如： The production is now three times what it was ten years ago.现在的产量是十年前的三倍。 6. 倍数 + more + 名词 + than +其他。如： There are nine times more books in his bag than in yours. 他书包里的书比你书包里的书多九倍。 7. 其他表达。如： She’s twice/ double my age. 她的年龄是我的两倍。 The average income of the staff has been increased by 50 percent compared with last year. 与去年相比，该单位职工的收入已增加了50%。 He runs faster than me by three times. 他跑得比我快三倍。 【考查方向】 1)倍数在句中的位置一般放在第一个as前面或比较级前面或名词前面。 2)用times表示倍数时，一般只限于表示包括基数在内的三倍或三倍以上的数。表示两倍可以用twice或double，一倍用once。
倍数的翻译
在汉英翻译中，我们经常会遇到数量增加、减少的问题。然而英汉两种语言在倍数增减的表达上存在着很大差异，别说翻译了，就算是拿一篇现成的段落或文章来考考大家的阅读理解能力，也未必所有人都能准确理解文章内容。请读者试着翻译这个句子：与去年同期相比，今年的出口总量增长了两倍。 译文：The total amount of the export has increased by three times, compared to the same time last year. 分析：该句涉及数量的变化。今年出口总量增加了两倍，是说在去年总量的基础上再增加了两倍。那么，也就是说今年的总量应该已经增长到去年同期的三倍。所以by three times为正解。这题前面讲过的了，加深一下印象。 表示陈述某个数量的句型 除最常用的系动词加数词之外，还可以用...go up to...，...as+adj. +as...，...has reached to...，...rise to...等。 例1 快过年了，大白菜的价格已接近3元一斤。 译文：The New Year is coming, and the price of the cabbage goes up to nearly 3 Yuan per kilogram. 表示数量比较和增减的句型 表示数量比较和增减的句型很多，大致包括...as...as...，...as...again as...，...数量词+as...as...，...as...as+数量词，...数量词+比较级+than...，比较级+than... by...，...数量词+the size(length，volume)of...，...数量词+that of...，...表增减的动词+by/ to/over/down...数量词。 例2 这种商店的价格是前一种商品的两倍。 译文：The price of this product is twice as much as that of the previous one. 例3 小轿车车速比大货车快一倍。 译文：The car runs as fast again as the truck. 例4：这只桶能装那只桶三倍的水。 译文：This barrel can hold three times as much water as that one. 例5 这家医院的缴费是一般医院的三至五倍。 译文：This hospital charges three to five times that of ordinary ones. 例6 去年该工厂的产量下降到2003年的65%。 译文：The output of that factory last year fell to 65% of the output in 2003. 特殊词语表示数量比较和增减 除了上面介绍的表示数量变化的句型之外，还有一些特殊的单词可以直接表示数量增减。这些单词通常用作形容词或动词，在句中充当表语或谓语。这些单词比使用某些句型来得更简洁，也比较容易掌握。 首先是以-ble和-ple结尾的表示倍数的词。这里介绍从"两倍"到"十倍"的英文表达，大家可以从中找出表述规律。 两倍double 三倍treble/ triple 四倍quadruple 五倍quintuple 六倍sextuple 七倍septuple 八倍octuple 九倍nonuple 十倍decuple 有读者或许会问："一倍"怎么说?如果说A的数量是B的一倍，那不就是A=B 吗?即：A equals B。如果说A比B多一倍，也就等于A的数量是B的两倍，就要用double一词了。所以英文里一般不说...as one time as...。但是有half as much again的说法，意为"一倍半"。
