本文简评了《理论和教学视角下的中介语变异》一书。从Labov学派的定量社会语言学与中介语变异研究的关联性出发,该书首先介绍了本族语者和非本族语者言语中的变异。然后从理论视角出发,介绍认知语言学和连接主义同变异理论的兼容。最后该书总结了理论视角下的一些教学启示。 This article briefly reviews the Book “Interlanguage Variations” from the perspective of theory and teaching. Starting from the relevance of Labov’s quantitative sociolinguistics and interlanguage variation research, this book first introduces the variations in the language of native and non-native speakers. Then from the theoretical perspective, it introduces the compatibility of cognitive linguistics and connectionism with the theory of variation. Finally, the book summarizes some of the teaching implications from a theoretical perspective.
