1、精選優(yōu)質(zhì)文檔-傾情為你奉上1）n times +形容詞（或副詞）比較級+thantimes是用來表示“乘”的（used to indicate multiplication）n times就是“乘以n”的意思。不論在任何句型中都包括基數(shù)100%在內(nèi)。1 Asia is four times larger than Europe.誤譯：亞洲比歐洲大4倍。正譯：亞洲比歐洲大3倍。評析：亞洲面積4400萬平方公里，歐洲面積1016萬平方公里。因此亞洲應(yīng)該是歐洲面積的四倍，即亞洲比歐洲大3倍。2 Sound travels nearly 3 times faster in copper than in

2、 lead.聲音在銅中的傳播速度幾乎比在鉛中快2倍。評析：聲音在銅中的傳播速度為2100m/s，在鉛中在的傳播速度為710m/s，可見聲音在銅中的傳播速度幾乎是鉛中的3倍，而不是比鉛快3倍。3 The volume of the earth is 49 times larger than that of the moon.地球的大小是月球的49倍?；颍旱厍虮仍虑虼?8倍。2) n times +形容詞（或副詞）原級+as4 The oxygen atom is nearly 16 times as heavy as the hydrogen atom.氧原子的重量幾乎是氫原子的16倍。評析：經(jīng)

3、查，氧原子的重量為，氫原子量為1。5 The mercury atom is about 5 times as heavy as calcium atom.汞的原子重量大約為鈣的5倍。評析：經(jīng)查，汞的原子量為，鈣的原子量為。3) by + n times6 The steel output has increased by two times.鋼產(chǎn)量已增加了一倍。評析：即增加了（原數(shù)目-1）倍。7 The error probability of the equipment was reduced by times through technical innovation.通過技術(shù)革新，該設(shè)備

4、的誤差概率降低了3/5。評析：reduced by times，漢語中不說“降低到二點五”，這時應(yīng)換算成整數(shù)分母，即降低到“五分之二”，或降低了“五分之三”。8 By using a new process the prime cost of the television set was reduced by times.采用一種新工藝使這種電視的主要成本降低了71%。評析：算成整數(shù)分母，即“降低到5/17” 或“降低了12/17”，但這樣仍不符合漢語習(xí)慣。在不要求絕對精確的情況下，可進(jìn)一步換算成百分?jǐn)?shù)，即“降低到29%”或“降低了71%”。另外，由倍數(shù)換算成分?jǐn)?shù)表示減少后的結(jié)果，譯成“減少到

5、幾分之一”或“減少為幾分之一”。例如，reduce by 3 times   減少到1/3  或減少了2/3reduce by 5 times   減少到1/5  或減少了4/5reduce by 10 times  減少到1/10  或減少了9/104)“倍數(shù)+upon/over”結(jié)構(gòu)表示“增加到n倍，增加了或超過了（n-1）倍”9 The industrial output in our factory this year is ten times over that of 1999.今年我們工廠的產(chǎn)量比199

7、到原來的1/3）13 The grain output in that county was two times over that of 1995.那個縣的糧食產(chǎn)量比1995年增加了一倍。5) 增減意義的動詞+倍數(shù)應(yīng)為“增加到原來的n倍”或 “增加了（n-1）倍”14 The cotton output in the county has increased four times.該縣棉花產(chǎn)量增加了3倍。15 The sales of TV set have risen fold.電視機(jī)銷售量增加了2倍半。16 The weight of the bicycle has decreased
