This paper, based on Construction Grammar and Metaphor Theory, explores the metaphorical mechanisms and functions of existential sentences in "The Four Dreams of Linchuan". Through objectification metaphors (such as container/entity metaphors), abstract concepts are concretized, and space-time transformation metaphors facilitate the mapping from spatial existence to psychological existence, achieving the expression of both virtual and real narratives. The study reveals the dual rhetorical functions of metaphor in cognitive salience (e.g., "broken well and collapsed wall" intensifying the image of heartbreak) and semantic enrichment (e.g., "book of merit" extending philosophical criticism). This paper innovatively employs the "补‘了’法" (complementing "le") to explain atypical existential sentence structures， expanding the rhetorical dimension of traditional grammatical research. It provides an interdisciplinary reference for the study of theatrical language and cognitive metaphor theory， and holds significant educational interpretation and teaching application value.
