ABSTRACT This paper presents a corpus-based analysis of obligatory full inverted and subject-operator inverted constructions in scientific texts. These are inversions obligatorily triggered by certain fixed preverbal constituents – as in ‘Here are some examples’ or ‘Nor did they know the entitlement criteria’ – since they are not replaceable in context by a comparable clause with SVX canonical word order because this is grammatically unavailable or conveys a different meaning. On the basis of a statistical analysis, it is argued that the distribution of these constructions in scientific texts is related to the degree of the addressor’s involvement in the text in question. It is further argued that the different types of obligatory inversions retrieved from the corpus may be seen to serve as discourse markers which convey addressor’s involvement in scientific writing. It will be shown that some obligatory inversions allow the presence of the addressor to change the addressee’s focus of interest or attention in the text, while other inversions allow the addressor to stress a particular constituent in the inverted clause, thus emphasising a comparative, restrictive or negative meaning.

科学文本中的强制倒置

摘要 本文提出了基于语料库的对科学文本中强制性完全倒置和主题运算符倒置结构的分析。这些是由某些固定的动词前成分强制触发的倒置——如“这里有一些例子”或“他们也不知道权利标准”——因为它们在上下文中不能被具有 SVX 规范词序的可比从句替换，因为这在语法上是不可用或传达不同的含义。在统计分析的基础上，有人认为这些结构在科学文本中的分布与发信人对相关文本的参与程度有关。进一步认为，从语料库中检索到的不同类型的强制倒置可以被视为表达作者参与科学写作的话语标记。将显示一些强制性倒装允许发话人的出现改变收件人在文本中感兴趣或注意的焦点，而其他倒装允许发话人强调倒装从句中的特定构成，从而强调比较性、限制性或消极的意义。
