解析
试题分析:此题考查分数的表示方法。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。分子超过1,分母要加s.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。根据语境可知此句的含义是这所学校的学生大约有四百人,其中五分之三的是男生。表示…的数量要用名词短语the number of,五分之三要用three fifths, 故选B。 点评:对于分数的考点有这么几个。第一是分子和分母的表示,到底是用基数词还是用序数词。第二,分子超过1时,分母的变化;第三分数做主语时谓语动词的取决,到底是用单数还是复数。 |
