题目内容
14.Threefifths (five) of the students have been league members since they came here.分析 五分之三的学生自从来来到这已经成为团员了.
解答 答案:fifths.结合后面的of the students,以及前面的基数词three,联想到这里是用分数,分子是基数词three,大于1,分母用序数词的复数,所给是基数词five五,序数词是fifth,复数加上s,故答案是fifths.
点评 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,序数词表示分母如果分子大于1,分母则要用复数形式.如:三分之一one-third;三分之二two-thirds,分数修饰的名词在句子中作主语时,谓语动词是用单数还是复数取决于名词,即与名词保持一致.如:Only one-fifth of air consists of oxygen.氧气只占空气的五分之一. About two thirds of the students are going to attend the meeting.大约三分之二的学生都将参加会议.
