●That’salmostonefifthoftheworld’spopulation.那几乎是世界人口的五分之一。onefifth意为“五分之一”。英语中分数的表达法:分子用基数词，分母用序数词；当分子大于一时，分母用复数。例如:threefourths四分之三

twothirds三分之二拓展:“四分之几”的分母可用quarter，例如:aquarter四分之一。“二分之一”用half，其后接名词要与of连用。当分数作主语时，谓语动词的单复数要与其后的名词保持一致。例如:Onethirdofthewaterisdirty.三分之一的水是不干净的。A.Threefourths；hasB.Threefourths；haveC.Threefourth；hasD.Threefourth；have做一做:单项选择。
