Pre-P Prepositional phrase, as "according to…" Ver-P Verb-object phrase, as "identify the fact that, determine the fact that…" Sentence Similar to Saussure's utterance, van Dijk's (2008) sentence is a part of social practices, and through semantic analysis with Wmatrix3.0 and ConcGram1.0, the causal clause (Cau-C) and a conditional clause (Con-C) are used to indicate the cognitive source and social function in CCJ Con-C…”
