The two constructions mainly differ in some aspects：highlight feature and highlight comparison,emphasis modality and emphasis cause,stress on inclusion and stress on affinity,focus on intangibility and focus on content,special collocation and com- mon collocation,semantic hierarchy and pragmatic hierarchy.
