【摘要】 请求是一种常见的社会行为,从序列结构来看,请求序列一般都会出现前扩展、中扩展及后扩展。前扩展的功能主要是请求者用以探测被请求者接受请求的可能性与方便程度,从而避免拒绝请求这一非优先行为的发生。被请求者则利用中扩展就请求的相关细节进行询问,以便对请求做出合适的回应,即接受或拒绝。后扩展主要是用以结束序列或执行其他与请求序列相关的行为。更多还原

【Abstract】 Requesting is a ubiquitous social action. In terms of sequence organization,the base sequence of requesting in Mandarin is generally expanded into pre-expansions or pre-sequences,insert expansions and post-expansions. Before making requests,the requester usually checks the availability and convenience of the requestee by pre-expansions to avoid the dispreferred response,i. e. refusal to requests. Meanwhile,the requestee also clarifies details related to requests before his or her acceptance of or refusal to requests by insert expansion. Besides,post-expansions,minimal or non-minimal,which are exploited either to close the sequence or to implement other social actions related to the request sequence.更多还原
