疑问句的主要功能是探询,但在特定的语境当中,它还能表达诸如请求、威胁、讽刺、劝告、责怪、感叹等意义,具有非疑问的语用功能。这是因为特定的语境可消除疑问标示所携带的疑问成分,使其疑问功能发生衰变或转移。分析疑问句的非疑问语用功能及其含义,对于正确理解疑问句的会话含义具有重要意义。 The main function of interrogative sentences is inquiry, but in certain contexts, it can express pragmatic functions such as request, threat, satire, advice, blame, exclamation and other meanings. This is because a particular context eliminates the question component carried by the question mark, decaying or diverting its questioning function. Analyzing the non-question pragmatic function of the questionary sentence and its meaning are of great significance for correctly understanding the meaning of the conversation in the questioning sentence.
