6的英文4的英文怎么写( 二 )


从以上例子可以看出:分子除用one外 , 也可用a;如果分子大于1 , 分母要用复数形式 。但是 , 1/2不能说a(one)second , 而要说a(one)half 。例如:
3.The sum of one half,one third and one fourth of a certain number is 13.某数的1/2,1/3和1/4的和是13 。
1/4和3/4可以说a(one)fourth和three fourths , 但常用a quarter和three quarters表示 。应该注意的是 , 分数修饰名词时 , 若该名词是不可数名词只能用单数;若是可数名词 , 用单数或复数均可 。但是 , 若它们在句子中作主语 , 则谓语动词是用单数还是复数取决于名词 , 即与分数所修饰的名词保持一致 。例如:
4.Only one-fifth of air consists of oxygen.氧气只占空气的1/5 。
5.About two thirds of the students attendthe meeting.大约2/3的学生都参加了会议 。
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:
6.You should finish the work within one and a fourth hours.你应在1.25小时内完成工作 。
7.The atom breaks up in a minute and a quarter.原子在1.25分钟内裂变 。
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:
8.Our bodies are 65percent water.我们人体含65%水分 。
9.Seventy-five percent of the earth'ssur- face is covered by water.地球表面的75%被水覆盖着 。
10.Eighty-five percent of the students in English department are girls.英语系85%的学生是女生 。
