His salary was incread by 10%.他的薪水增加了10%。
规定英文Their salar ies increas annually by one hundr ed dollars.他们的薪水每年增加100美元。english
They have incread the pr ice of petrol by almost 20%.他们把汽油价格提高了将近20%。
The physician incread the dosage from one to four.医生把剂量从1剂增加到4剂量。
英语increa by究竟如何正确译成汉语，存在着两种不同的意见。一说译成“增长了”；二说译成“增长到”，跟increa to同义。可以说，坚持第一种意见的人目前为数不少，几乎要占大多数，因为目前国内出版的一些权威刊物在论述这个问题时，多数都是坚持第一种意见是正确的。例如：
雅思阅读技巧①The output incread by over 200 percent．产量增长了两倍多。
②As against last year，our coal output has incread by three times．与去年相比，我们的煤产量增加了3倍。
③Many counties have incread their farm output by 100 percent or more within a short space of time．许多县在短短的一个时期使粮食产量增长了一倍或一倍多。
④Over the past 17 years，Taching has incread its annual output of crude oil by an average of 28 per cent.大庆原油产量在过去17年间平均每年增长28％。
很明显，上述例句都是中国人自己造出来的，究竟能不能符合英美人的表达方法，只有同英美语言的国家出版的刊物中例句相比较，才能鉴定。
①The strength of the attraction, or repulsion, between two electric charges is doubled if the amount of electricity in one of the charges is doubled; it increas by 2×2=4 times if the distance between the original charges is halved．我们知道，引力(或斥力)和距离的平方成反比，因此距离缩短一半，引力或斥力(increa by 2×2=4 times)增长到四倍，不是增长了四倍。
②When the signal we pick up has incread by 10 times the gain may have been reduced by 8 times，and the loudness will only have gone up 10／8=1.25 times．
信号增大到10倍，增益降低到1／8，音量只增大到10／8=1.25倍。thx
③Suppo a crate weighing 300 pounds is to be raid to the floor of a truck 4 feet above the ground．．．If the length of the incline is 20 feet，the man must push upward along the incline with a force of 60 pounds(60×20=1200 ft.-lbs．) That is，if the force is decread 5 times (from 300 pounds to 60 pounds), the length must be incread 5 times.
原文告诉我们：the length 4 feet is incread 5 times表示4 feet×5=20 feet．
下面举一例同increa用法相同的词ri。
In 1979，food prices，not to mention prices of other esntials，ro 12-3％, while wages ro by only 8.5％.
很明显，这句里的lo和ro by同义。

综观上述几例，我们不难看出，英美语言中关于“增加”的表达方法同我们汉语大有不同，与我们历来固守的第一种表达方法是格格不入的。关于我们历来固守的第一种“增加”表达方法在英美刊物中根本找不出，
相反，关于第二种表达方法的例句却俯拾即是。因此，我们完全同意结论：increa 3 times，increa to 3 times 和increa by 3 times三者同义，即意思都是“增加到三倍”，即“乘三”。
下面顺便提一下“A is three times larger than B”的译法。
武汉汉街地址众所周知，我们大多数人历来认为这句话译为“A的大小是B的四倍”，即“A比B大三倍”是无可非议的。殊不知，我们又弄错了。该句应译为：“A的大小是B是三倍；或A的大小三倍于B；或A比B 大两倍”。
机器人能过夫妻生活吗
换句话说,“A is three times larger than B，”或“A．is larger than B by three times”和“A is three times as large as B”三句都是同义的。新歌快递
