修辞学中有四种类型话语:表达信息的话语、影响言行的话语、言语即行为的话语、抒发情感的话语。话语类型不同,人们的修辞要求也就不同。对表达信息的话语来说,传递真实、切题、适量的信息成为人们对这种类型话语的修辞要求。然而,由于修辞现象的复杂多样性,有时人们在交际中传递的信息不真实、不切题、也不适量,反而能取得很好的表达效果。零信 There are four types of discourse in rhetoric: words that express information, words that affect words and deeds, words that act, and emotions.
