【語義表述】他就這個(gè)課題發(fā)表權(quán)威意見。

【錯(cuò)誤表述】He spoke with the authority on the topic.

【講解辨析】我們看名詞authority在這句話中的確切意思和用法。確切地的說，authority在這句話中是用于knowledge（知識(shí)）方面。It means the power to influence people because they respect your knowledge or official position. 那么，表示“具有權(quán)威性地”這個(gè)意思，有個(gè)固定的搭配模式：with authority，在authority前面不要加任何冠詞。請看下面的例句：

Like such a recognition of merit It' seemed to come with authority. 這種對功勞的贊許只能來自權(quán)威之口。

回顧開篇的說法：He spoke with the authority on the topic. 這里authority前面使用了定冠詞the，我們將之去掉即可。

【正確表述】He spoke with authority on the topic.
