So I mean the kind of speech that you see someone giving in an old movie where they clear their throat, and they go, "Ahem, ladies and gentlemen," and then they speak in a certain way which has nothing to do with casual speech.
我的意思是那种你在一部老电影里看到的演讲， 人们会清一下喉咙，然后说： “啊喝，女士们，先生们，” 然后，他们会用一种和现在说话完全不同的方式讲下去。
