学术语篇中词汇隐喻有其独特的特点和功能，深入研究隐喻的用途，人们能够更容易地理解学术性词汇。本文从词汇隐喻层面，对比分析了语言学和计算机科学学术论文“学习”隐喻构建的异同并揭示了产生差异的原因。结果表明，语言学领域“学习是过程”和计算机领域“学习是方法”这两类隐喻分支下的多个隐喻类型没有显著区别，一定程度上证明了“学习是方法”还不是新隐喻。由于不同的学科体验产生了不同的认知方式，产生了源域和目标域间的不同映射，因此，本文还发现隐喻“学习是教育”、“学习是旅程”更多出现在语言学领域，而“学习是战争”更多出现在计算机领域。
Lexical metaphor in academic discourse has its unique features and functions. It is easier for people to understand academic terms by studying the use of metaphors in depth. In this study, a corpus-based comparative study was conducted, systematically investigating lexical metaphor construction of the learning in academic discourse of applied linguistics and computer science, and revealing the reasons for the differences. Results showed that there was no significant difference between the “learning is a process” in linguistics and “learning is a method” in the field of computer science, which indicates that “learning is a method” is not a new metaphor. This paper also found that metaphors “learning is education” and “learning is journey” appeared more in linguistics while “learning is war” appeared more in the field of computer. One possible reason for this is that different subject experiences produce different cognitive ways and different mappings between source and target domains.
