问题五:3/4 的英文怎么写 基数词+序数词
threequarter(s)
四分之三
two-thirds [ 'tu:'θ:dz ]
num 三分之二
英语分数的表示法:)~~
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。
2.However,the number of boys will bea third or less than the girls in the class.但是,班里男生的人数将比女生少三分之一或更少。
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丹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。>>

问题六:4:00钟用英语单词怎么写? 来了

英文:four

美式读音:fɔːr

英式读音:fɔːr

复数:fours

例句:

1、The four were arrested by the police for theft

2、Runner number four reached the finish line near the end of the race
