英語分數的表示法:)~~
一、用“基數詞+序數詞”表示
分數在英語中通常是借助于基數詞和序數詞來共同表達的。其中基數詞表示分子,序數詞表示分母。
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,或者說是米的百分之一。
2.However,the number of boys will bea third or less than the girls in the class.但是,班里男生的人數將比女生少三分之一或更少。
從以上例子可以看出:分子除用one外,也可用a;如果分子大于1,分母要用復數形式。但是,1/2不能說a(one)second,而要說a(one)half。例如:
3.The sum of one half,one third and one fourth of a certain number is 13.某數的1/2,1/3和1/4的和是13。
1/4和3/4可睜肆枯以說a(one)悉洞fourth和three fourths,但常用a quarter和three quarters表示。應該注意的是,分數修飾名詞時,若該名詞是不可數名詞只能用單數;若是可數名詞,用單數或復數均可。但是,若它們在句子中作主語,則謂語動詞是用單數還是復數取決于名詞,即與分數所修飾的名詞保持一致。例如:
4.Only one-fifth of air consists of oxygen.氧氣只占空氣的1/5。
5.About two thirds of the students attendthe meeting.大約2/3的學生都參加了會議。
帶分數也是常見的英語數詞表達。所謂帶分數,實際上是“整數+分數”,表達時分而述之,只是整數部分與分數部分要用連詞 and連接。當帶分數修飾名詞時,該名詞通常是復數,但若名詞置于整數one或a之后,則用單數。“帶分數+名詞”作主語時,謂語動詞根據臨近原則要用復數。例如:
6.You should finish the work within one and a fourth hours.你應在1.25小時內完成工作雹伍。
7.The atom breaks up in a minute and a quarter.原子在1.25分鐘內裂變。
二、用per cent等表示
表示百分之一可以說one(a)hundredth,但更常用one percent或per cent,即用百分數表示法來表達。例如:
8.Our bodies are 65percent water.我們人體含65%水分。
9.Seventy-five percent of the earth'ssur- face is covered by water.地球表面的75%被水覆蓋著。
10.Eighty-five percent of the students in English department are girls.英語系85%的學生是女生。
三、用part表示
名詞part有“……分之一”的意思,分子大于1時,part用復數。表示分數的結構一般有以下三種:
(1)“基數詞(或a)+序數詞+part(s)” a hundred part百分之一
(2)“基數詞+part(s)+in+基數詞” five parts in one thousand千分之五
(3)“基數詞+part(s)+per+基數詞” one part per million百萬分之一
四、用“基數詞+介詞+基數詞”表示
借助介詞表示分數,介詞前的數詞是分子,介詞后的數詞是分母。例如:
11.Ninety-nine people out of a hundred,if they were asked who first found America, would answer Clumbus.如果要問是誰首先發現美洲,一百個人中有九十九個(百分之九十九)將回答是哥倫布。
這種結構中的介詞主要有in,out of,of以及to
