What are the four maxims of the Cooperative Principle? Please give examples to show how the flouting of these maxims gives rise to conversational implicature(Give at least two examples, each flouting a different maxim)
【正确答案】：The four maxims of the cooperative principle are maxim of quantity, maxim of quality maxim of manner and maxim of relation. Example 1A: The hostess is an awful bore. Don't you think? B: The roses in the garden are beautiful aren't they? This is said when it is known to both A and B that it is entirely possible for B to make a comment on the hostess. Thus B is saying something irrelevant to what A has just said, and flouting the maxim of relation. The implicature produced is"I don't wish to talk about the hostess in such a rude manner. "Example 2A: Shall we get something for the kids?: Yes. But I veto I-C-E-C-R-E-A-M. This is said when it is known to both A and B that B has no difficulty in pronouncing the word "icecream". Thus B has flouted the maxim of manner. The implicature produced"I don't want the kids to know we are talking about icecream. "(P121)
