分?jǐn)?shù)詞由“基數(shù)詞+序數(shù)詞”構(gòu)成，基數(shù)詞表示“分子”，序數(shù)詞表示“分母”。當(dāng)“分子”大于1時(shí)，“分母”要用復(fù)數(shù)形式。比較：one third三分之一，two thirds三分之二，three fifths五分之三，four sevenths七分之四。

重要補(bǔ)充

1.

考查分?jǐn)?shù)詞用法的試題，還常結(jié)合主謂一致進(jìn)行考查。此時(shí)，我們要依照分?jǐn)?shù)詞所修飾的名詞來確定句子的謂語用單數(shù)還是用復(fù)數(shù)。如果所修飾的是復(fù)數(shù)形式的可數(shù)名詞，謂語要用復(fù)數(shù)形式;如果所修飾的是不可數(shù)名詞，謂語要用單數(shù)形式。比較例句：

One third of the people there are farmers.那里三分之一的人是農(nóng)民。

Two thirds of the work has been done.這項(xiàng)工作的三分之二已經(jīng)完成。

2.

population (人口)要用單數(shù)形式，但表示“百分之幾的人口”作主語時(shí)，謂語動(dòng)詞卻要用復(fù)數(shù)形式。如：

Over 80 per cent of our whole population are peasants.我國總?cè)丝诘陌俜种�八十以上是農(nóng)民。

Twenty percent were dropped in the examination.有百分之二十的人考試不及格。
