2。3。2 The Politeness Principle

Leech (1983) claims there are six maxims in the politeness principle including tact maxim, generosity maxim, praise maxim, modesty maxim, agreement maxim and sympathy maxim。 The six maxims strategies help to maintain social cohesion to avoid conflicts/ disharmony。 

"Politeness allows people to perform many inter-personally sensitive actions in a nonthreatening or less threatening manner。 (Holtgraves, 2002)

Politeness principle include two main strategies in the conversations, they are positive politeness strategies and negative politeness strategies。

 Positive politeness strategies are intended to avoid giving offense by highlighting friendliness。 These strategies include making compliments, creating agreements and using jokes。

Negative politeness strategies are intended to avoid giving offense by showing deference including questioning, hedging, and presenting disagreements as opinions。

The relationship between cooperation principle (CA) and politeness principle (PP):

CA is a general idea when people talk about the analysis of conversations in the literature works。 Turn-taking and CP/PP are specific methods used in conversation analysis。 CA and PP rules are the basic principles for speakers in the conversation。 CA rule is made to ensure the truth and accuracy of language so that the conversation can achieve the efficiency maxim。 The PP rule is mainly emphasis the “face value” and friendliness。 This two principles are often cross used in the meantime which leads to conflicts in the communication。 In the book “the cask of amontillado”, the violations of CA and PP rules happen many times。 来,自,优.尔:论;文*网www.youerw.com +QQ752018766-

The politeness principle is used to compare the different speaking manner between different speakers and the change of their mental status。

2。4 Brief Introduction of “The Cask of Amontillado”

The story is set in a nameless Italian city in an unspecified year (possibly in the 18th century) and is about the narrator's deadly revenge on a friend whom he believes has insulted him。 Like several of Poe's stories, and in keeping with the 19th-century fascination with the subject, the narrative revolves around a person being buried alive—in this case, by immurement。 Although the subject matter of Poe's story is a murder, "The Cask of Amontillado" is not a tale of detection like "The Murders in the Rue Morgue" or "The Purloined Letter"; there is no investigation of Montresor's crime and the criminal himself explains how he committed the murder。
