言语交际中,说话人想表达的有时是直接的字面意思,有时是间接的字面以外的隐含意义。言语行为理论指出当一个人说话时会同时产生三种行为:言内行为、言外行为和言后行为。言语行为理论最关注的是言外行为,它试图解释说话者的言外之意。在听力理解过程中学生只有通过语境才能正确理解说话人和听话人的“言外之意”。 In verbal communication, what the speaker wants to express is sometimes the direct literal meaning and sometimes the indirect implicit meaning beyond the word. Speech act theory points out that when a person speaks, there are three kinds of behaviors simultaneously: speech act, speech act and post-speech act. Speech act theory is most concerned with extrajudicial behavior, it attempts to explain the speaker’s implication. In the process of listening comprehension, students can understand the “implication” of the speaker and hearer correctly only through the context.
