试比较: 1.She knows me better than he.她比他更了解我。 2.She knows me better than him.她了解我超过了解他。 句 1 的完整形式是:She knows me better than he knows me.than 从句中省略了 knows me;句 2 的完整形式是:She knows me better than she knows him.than 从句中省略了 she knows。 需要注意的是,在遇到主格、宾格相同的 you 时,句子就不能省略了,否则会产生歧义。例如: She knows me better than you. 此句既可理解为:She knows me better than she knows you.她了解我超过了解你。 也可理解为:She knows me better than you do.她比你更了解我。 当 than 后的名词是普通名词时,句子也不可省略,以免产生歧义。例如: She knows me better than my parents. 应说:She knows me better than my parents do.她比我的父母更了解我。 或说:She knows me better than she knows my parents.她了解我超过了解我的父母。
