倍数英文

（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： 倍数 + as + many + 可数名词复数 + as； 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

1.倍数+as...as2.倍数+比较级+than3.倍数+the+名词+of如，Thisbridgeisthreetimesaswideasthatone.（这座桥是那座桥的三倍宽。）=Thisbridgeistwicewiderthanthatone.（这座桥比那座桥宽两倍。）=Thisbridgeisthreetimeswidthofthatone.（这座桥的宽度是那座桥的三倍。）

1）n times +形容词（或副词）比较级+than…times是用来表示“乘”的（used to indicate multiplication）n times就是“乘以n”的意思。不论在任何句型中都包括基数100%在内。[1] Asia is four times larger than Europe.误译：亚洲比欧洲大4倍。正译：亚洲比欧洲大3倍。评析：亚洲面积4400万平方公里，欧洲面积1016万平方公里。因此亚洲应该是欧洲面积的四倍，即亚洲比欧洲大3倍。[2] Sound travels nearly 3 times faster in copper than in lead.声音在铜中的传播速度几乎比在铅中快2倍。评析：声音在铜中的传播速度为2100m/s，在铅中在的传播速度为710m/s，可见声音在铜中的传播速度几乎是铅中的3倍，而不是比铅快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。或：地球比月球大48倍。2) n times +形容词（或副词）原级+as[4] The oxygen atom is nearly 16 times as heavy as the hydrogen atom.氧原子的重量几乎是氢原子的16倍。评析：经查，氧原子的重量为15.9994，氢原子量为1。[5] The mercury atom is about 5 times as heavy as calcium atom.汞的原子重量大约为钙的5倍。评析：经查，汞的原子量为200.59，钙的原子量为40.08。3) by + n times[6] The steel output has increased by two times.钢产量已增加了一倍。评析：即增加了（原数目-1）倍。[7] The error probability of the equipment was reduced by 2.5 times through technical innovation.通过技术革新，该设备的误差概率降低了3/5。评析：reduced by 2.5 times，汉语中不说“降低到二点五”，这时应换算成整数分母，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 3.4 times.采用一种新工艺使这种电视的主要成本降低了71%。评析：算成整数分母，即“降低到5/17” 或“降低了12/17”，但这样仍不符合汉语习惯。在不要求绝对精确的情况下，可进一步换算成百分数，即“降低到29%”或“降低了71%”。另外，由倍数换算成分数表示减少后的结果，译成“减少到几分之一”或“减少为几分之一”。例如，reduce by 3 times 减少到1/3 或减少了2/3reduce by 5 times 减少到1/5 或减少了4/5reduce by 10 times 减少到1/10 或减少了9/104)“倍数+upon/over”结构表示“增加到n倍，增加了或超过了（n-1）倍”[9] The industrial output in our factory this year is ten times over that of 1999.今年我们工厂的产量比1999年增加10倍。（×）今年我们工厂的产量是1999年的10倍。[10] He is five times upon your age.他是你年龄的5倍。[11] The total output value of the city’s light industry has grown over three times as against last year.这个城市的轻工业总产值比去年增长了两倍多。[12] The number of the students in that school has been decreased more than 3 fold.该校学生人数减少了2/3。（即减少到原来的1/3）[13] The grain output in that county was two times over that of 1995.那个县的粮食产量比1995年增加了一倍。5) 增减意义的动词+倍数应为“增加到原来的n倍”或 “增加了（n-1）倍”[14] The cotton output in the county has increased four times.该县棉花产量增加了3倍。[15] The sales of TV set have risen 3.5 fold.电视机销售量增加了2倍半。[16] The weight of the bicycle has decreased 3 times.这种自行车的重量减少了2/3。（即减少到1/3）[17] The length of the rope has been shortened 5 fold.绳子的长度缩短了4/5。（即缩短到1/5）[18] If there were a bridge here, the distance would be shortened 4 times.如果这里有座桥，距离将缩短3/4。6)“表示增减意义的词+to+倍数”句型常译为“增（降）至n倍”[19] The number of the students has increased to three times.学生人数增加到3倍。[20] The price of rice has reduced to two thirds.大米的价格减到原价的2/3。① Exceed (increase, decrease, reduce)+by a factor of +倍数增加到n倍，减少到1/n倍[21] The speed exceeded the average speed by a factor of 2.5.该速度超过平均速度的1.5倍。[22] The price of farm tools has decreased by a factor of 4.农具降到原价的1/4。[23] This equipment will reduce the error probability by a factor of 5.这种设备使误差概率降低到原来的1/5。② 表示“2倍”时，不能用two times，除了twice外，还可以用double， as …again as等[24] He demanded double the usual fee.他要了比平常多1倍的路费。[25] A is as long again as B.A的长度是B的2倍。③ 表示“3倍”时，除可用three times外，还可用动词treble或triple等表示。[26] The grains in the area have trebled this year.今年这个地区的粮食增加了2倍。[27] Output should triple by next year.到明年产量应增至三倍。④ 在表示“4倍”或“4倍以上”时，除用“基数词+times”外，还可用“基数词+fold”的合成词。[28] We have produced four-fold as many electric fans as we did last year.本年我们生产的电扇数量相当于去年的4倍。[29] During that period its total output of industry increased (to) ten-fold.在那个时期，工业总产值增加了9倍。⑤ 在表示“不到1倍”时，还可用“分数+as …again as”表示。[30] A is half as much again as B.A比B多一半。7) 倍数+the size (length, height) of …表示[31] Shanghai is about 4 times the size of Changsha.Shanghai is about 4 times as large as Changsha.上海大约有长沙的4倍那么大。[32] In this workshop the output of July was 3.5 times that of January.In this workshop the output of July was 3.5 times as much as that of January.这个车间7月份的产量是1月份的3.5倍。

这件衣服比那件贵两倍有3种表达方式,用例句说明Hishouseisthreetimesasbigasours.=Hishouseisthreetimesbiggerthanours.=Hishouseisthreetimesthesizeofours.其中,表示一倍和两倍时,threetimes那个位置用once/twice代替oneandahalf表示1.5倍的...比如,oneandahalfhours一个半小时

sextuple 六倍septuple 七倍octuple 八倍nonuple 九倍decuple 十倍elevenfold，eleven times 十一倍twelvefold，twelve times 十二倍后面的都是“英文数字”+times或者“英文数字”后面直接接“fold”表示多少倍

oncedoubletriplequadruple一般后面都用times比如： five times ten times twenty-one times one hundred times
