Abstract:In the study of the ellipsis structure of modern Chinese, very few researches were made on the role of focusing adverbs.This paper proposes that the semantic function of the focusing adverbs meets the focus anchoring condition and parts of the temporal anchoring conditions of the generalized anchoring principle (GAP), thereby improving the acceptability of ellipsis sentences.The different semantic functions and syntactic positions of the focusing adverbs "cai"才, "jiu"就, "ye"也, "dou"都 and "que"却 also affect the licensing and identity of ellipsis structures.As for the co-occurrence of different focusing adverbs, we suggest that different focusing adverbs have different syntactic positions, which is consistent with the one functional head in one focus projection assumption, while the semantic orientation of focusing adverbs is only an effect of the raising of noun phrases.
