試題分析:此題考查分數(shù)的表示方法。分數(shù)在英語中通常是借助于基數(shù)詞和序數(shù)詞來共同表達的。其中基數(shù)詞表示分子,序數(shù)詞表示分母。分子超過1,分母要加s.分數(shù)修飾名詞時,若該名詞是不可數(shù)名詞只能用單數(shù);若是可數(shù)名詞,用單數(shù)或復(fù)數(shù)均可。但是,若它們在句子中作主語,則謂語動詞是用單數(shù)還是復(fù)數(shù)取決于名詞,即與分數(shù)所修飾的名詞保持一致。根據(jù)語境可知此句的含義是這所學校的學生大約有四百人,其中五分之三的是男生。表示…的數(shù)量要用名詞短語the number of,五分之三要用three fifths, 故選B。
考點:分數(shù)的基本用法。
點評:對于分數(shù)的考點有這么幾個。第一是分子和分母的表示,到底是用基數(shù)詞還是用序數(shù)詞。第二,分子超過1時,分母的變化;第三分數(shù)做主語時謂語動詞的取決,到底是用單數(shù)還是復(fù)數(shù)。
