【正确答案】正确答案：Cooperative Principle is the principle suggested by Grice about the regularity in conversation, which reads " Make your contribution such as required, at the stage at which it occurs, by the accepted purpose or direction of the talk exchange in which you are engaged. " There are four categories of maxims under it, namely, quality maxim, quantity maxim, relation maxim, and manner maxim.(2 points) As in this mini-talk, at the level of what is said, the second speaker violates the maxim of Quantity, that is, make your contribution as informative as is required(for the current purposes of the exchange); and do not make your contribution more informative than is required, as well as the maxim of Relation, that is, be relevant.(4 points) Obviously, the speaker B does not give enough relevant information. However, at a deeper level, based on the common knowledge shared by A and B, it is very easy for speaker A to infer that since B has been unwell for the whole morning, B did not have lunch at all. This is the implicature caused by the violation of cooperative principle.(4 points)

【答案解析】解析：考查合作原则。表面看来，以上对话违反了合作原则中的数量准则：使你所说的话如所要求的那样信息充分，不要使你的话语比所要求的信息更充分。同时也违反了关联准则，即说出的话语要切题，不说与主题、论题或话题无关的话。但是基于两人的共有知识，A很容易推断出：因为B感觉不舒服，所以B实际上是在告诉A自己什么也没吃，因此在某种程度上B遵守了数量和关联准则。会话含义也就因此产生了。
