二语学习者过度使用名词化的句法语义特征研究
The Study on Syntactic and Semantic Features of Overuse of Nominalization by L2 Learners

名词化是学术英语和其它正式书面语体最重要的特征之一，但过度使用名词化会导致语篇晦涩难懂，引起语义模糊或歧义。笔者以162篇金融专业本科生连续三年的期末学术写作论文为语料，研究了二语学习者在学术英语写作中是否存在因过度使用名词化而导致的语义模糊或歧义现象，结果表明学术英语写作中确实存在名词化滥用现象。过度使用名词化所导致的语义模糊或歧义的句子具有如下特征：1) 多个名词化连用；2) 复合前置修饰语修饰名词化；3) 复合后置修饰语修饰名词化；4) (多个)抽象意义的后置介词短语修饰名词化；5) 词汇密度过高或表抽象意义的定语从句修饰名词化；6) 名词化本身一词多义；7) 以上6种类型的交叉。
Nominalization is one of the most important features of academic English and other formal written styles, but overusing nominalization will make the article become static, lengthy and abstract, and even lead to the abuse of nominalization, which will eventually cause semantic fuzziness or ambiguity. Based on the 162 academic course papers of undergraduates majoring in finance for three consecutive years, this paper explored whether there was semantic fuzziness or ambiguity caused by overuse of nominalization by L2 learners in academic writing. The results showed that semantic fuzziness or ambiguity caused by overuse of nominalization has the following syntactic and semantic features: 1) successive use of multiple nominalization; 2) nominalization modified by compound premodifiers; 3) nominalization modified by compound postmodifiers; 4) nominalization modified by (multiple) abstract prepositional phrases; 5) nominalization modified by attributive clause(s) with high lexical density or abstract meaning; 6) polysemous nominalization; 7) the crossover of the above six types.
