【正确答案】正确答案：There could be generally two types of implicature in which this utterance make. One may be that speaker B wants to emphasize it is the pattern that make the skirt beautiful. The other may be that speaker B doesn"t like the woman who wear the skirt. According to the cooperative principle, in our conversation, in order to be cooperative, that is, to make his intentions to be known by the hearer, the speaker will try to make his conversational contribution such as is required, at the stage at which it occurs. Therefore, according to the third maxim of cooperative principle, RELATION, which says "be relevant", the utterance could be interpreted differently as follows; In the first situation, when speaker B hear speaker A saying "The skirt she is wearing is beautiful" , he/she wants to add that the pattern is especially good. The utterance is actually relevant to the context and further stress the beauty of the dress. In the second situation, speaker B doesn"t like the woman who wear the skirt, but according to the Politeness Principle, in order to be polite, speaker B would violate the maxim of relation, thus to make the utterance euphemistic. By emphasizing it is the pattern that makes the skirt beautiful, speaker B gives an implication that the woman who wears the skirt is not so nice.
