The collocation of double quantity patterns in modern Chinese can be classi-fied into juxtaposing type(including causal type and coordination type),adversative type and distributive type.The usage of adversative type is more unlimited.Based on an analysis of the expectation structure of double quantity patterns,it shows that there is an antithesis of causal relation and adversative relation in the semantics of double quantity patterns.The key to interpreting double quantity patterns is a subjective perspective.An inference perspective indicates high probability events that meet common expectations,leading to a causal inter-pretation.A reductive perspective indicates events of low probability and counter-expecta-tion,leading to adversative interpretation.The former is a marked interpretation,so it is generally necessary to provide more markers or special expressions in the discourse.
