This paper discusses the relationship between lexical collocation and its near-synonymy of “băi”and “fàng” by surveying the Academia Sinica Balanced Corpus of Modern Chinese. Three categories of lexical collocation are proposed teaching: typical collocation, idiomatic collocation and syntactical high-frequency collocation. Based on the corpus results, two differences between “băi”and “fàng” are generalized: 1) “băi”is used to describe the static state of an object, while “fàng” the dynamic disposal; 2) “băi”has further meaning of setting up something for an active purpose, while “fàng” lacks this meaning.
