元语言否定的否定对象不是事实本身 ,而是陈述的前提、会话含义、言谈焦点和视点、社会内涵以及语言表达手段等。元语言否定并不是语言表达式固有的内在性质。即使是看来十分典型的元语言否定现象 ,在特定的语境里也可能转变为普通的、非元语言的否定。由否定和肯定两部份相互对照构成的句子并不一定用作元语言否定。这些情况都是在元语言否定研究中应该注意的问题 The negative object of meta-linguistic negation is not the fact itself, but the premise of the statement, the meaning of the conversation, the focus and perspective of the speech, the social connotation and the means of language expression. Metalanguage denial is not inherent in linguistic expressions. Even the seemingly very typical denial of the metalanguage may translate into ordinary, non-metaphorical negations in a particular context. Sentences composed of negative and positive parts are not necessarily used as meta-verbal negations. These are the questions that should be paid attention to in the metalanguage negation research
