[誤] We are interested in world affair now.
[正] We are interested in world affairs now.
注:affair 指與公眾有關(guān)的“事務(wù)”時,須用復(fù)數(shù)形式,所以誤句中的world affair 須改為world affairs。另外,
current affairs(時事),foreign affairs(外交事務(wù)),affairs of state(國是)等,也都用復(fù)數(shù)形式。在指“(關(guān)系到某個人的事)時,用單數(shù)。在指某一事件時,用單數(shù),在 have an affair with sb.(與某人私通)這個固定詞組中用單數(shù)。
