1) Sentence meaning refers to the intrinsic property of the sentence itself in terms of a predication; It is abstract and decontextualized. For example, semantic analysis of the sentence meaning of "The bag is heavy" results in the one-place predication BAG (BEING HEAVY).
2) Utterance meaning is based on sentence meaning: it is the realization of the abstract meaning of a sentence in a real situation of communication, or simply in a context; It is concrete and context-dependent. For example, the pragmatic analysis of the utterance meaning of "The bag is heavy" in different contexts can be a statement, a request for help and even declination to someone's request for help.
1)句子意义是指句子本身在谓项上的内在属性，它是抽象的、脱离语境的。例如，对“包很重”的句子意义进行语义分析就会导致一位述谓结构——包(很重)。
2)话语意义是以句子意义为基础的：它是在真实的交际情境中或简单地在语境中实现句子的抽象意义，它是具体的、依赖语境的。例如，在不同的语境中，对“包很重”的话语意义的语用分析可以是一种陈述，一种求助请求，甚至是降为对他人的求助。
