However, anaphora alone cannot contribute to ironic effect, and only by resorting to other resources like contextual information, can anaphora generate irony. Therefore, Yus＇ s classification of contextual sources is employed to analyze with examples how anaphora creates irony by the aid of context. Ultimately, the conclusion has been drawn that anaphora is able to produce irony with the help of six groups of contextual information classified by Yus except the category--speaker＇s nonverbal behavior and anapbora sometimes has to interact with several groups of contextual information in order to create irony.展开更多
