The Functional expansion of Dui(对)in Communicative Interactions:from the Perspective of Constructional Competition
In modem Chinese,Dui(对)and Shi(是),as responses,indicate confirmation,agreement and other meanings,and appear frequently in natural conversation,and the functional coincidence of discourse is high.However,in the communicative interaction,the function of Dui(对)shows an expanding trend.First,the function of response expands,and Dui(对)evolves towards the direction of response discourse markers;The second is to expand the function of Shi(是),and Dui(对)occupies the priority position of Shi(是).Based on the constructional competition theory,the paper argues that the use of Dui(对)and Shi(是)is differentiated due to the high frequency use of Dui(对)and the multifunctional response function.The strong textual response function of Shi(是)limits the range of response of Shi(是),and focuses on the factual and upper-level primes.Subjective judgment of meaning,strong expressiveness,weak subjective conflict and appropriate oral style are the four factors that provide competitive power for Dui(对).
