1.In the last two years, only six people were found guilty of poaching charges out of forty-one arrested.

six out of forty one分数

一、用“基数词+序数词”表示
分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子,序数词表示分母。
如:


1.The centimeter is one-tenth of the decimeter or one-hundredth of the meter.厘米是分米的十分之一,或者说是米的百分之一。

带分数也是常见的英语数词表达。所谓带分数,实际上是“整数+分数”,表达时分而述之,只是整数部分与分数部分要用连词 and连接。当带分数修饰名词时,该名词通常是复数,但若名词置于整数one或a之后,则用单数。“带分数+名词”作主语时,谓语动词根据临近原则要用复数。例如:

2.You should finish the work within one and a fourth hours.你应在1.25小时内完成工作。

二、用per cent等表示

表示百分之一可以说one(a)hundredth,但更常用one percent或per cent,即用百分数表示法来表达。例如:

3.Our bodies are 65percent water.我们人体含65%水分。

三、用part表示
 
名词part有“……分之一”的意思,分子大于1时,part用复数。表示分数的结构一般有以下三种:
1“基数词(或a)+序数词+part(s)” a hundred part百分之一
2“基数词+part(s)+in+基数词” five parts in one thousand千分之五
3“基数词+part(s)+per+基数词” one part per million百万分之一

四、用“基数词+介词+基数词”表示

借助介词表示分数,介词前的数词是分子,介词后的数词是分母。例如:

Ninety-nine people out of a hundred,if they were asked who first found America, would answer Clumbus.如果要问是谁首先发现

美洲,一百个人中有九十九个(百分之九十九)将回答是哥伦布。

这种结构中的介词主要有in,out of,of以及to

The map is drawn to a scale of one of ten thousand.这张地图是按万分之一的比例绘制的。

2.Adding to the problem, poachers today are more skilled at killing rhinos, and not only with guns.

add to增加, 加强

例句:This lesson adds to the value of the book.
      这一课增加了这本书的价值。

      Since then, the palace has often been added to, rebuilt and repaired.
       从那以后, 那座宫殿不断得到扩建和修缮。

3.Africa had an estimated seventeen thousand white rhinos and four thousand black rhinos as of two years ago.

as of在…时,到…时为止,从…时起

例句:As of tomorrow, I am responsible for this group.
       从明天开始,我将对这个团体负责。

      As of now, they won't return my e-mails.
      直至现在,他们还没有答复我的电子邮件。
