Chunks, as fixed or semi-fixed structures, are the unity of grammar, semantics, and context which play an important role in the process of language comprehension and generation. This paper gives a brief introduction to the definition and classification of chunks, and makes an in-depth analysis of the use of chunks in 95 Chinese EFL learners’ compositions on the basis of the classification of chunks by Nattinger and DeCarrico. For the incorrect chunks in the compositions, this paper makes qualitative analysis and classifies them into redundancy, avoidance, tense, mixing, and chunks creation. According to the analysis, four suggestions on chunks teaching are put forward in order to explore effective measures to promote chunks teaching and help language learners improve their practical application ability of English. 展开更多

Metaphor,as a systematic expression of human thinking,action and thought,is not only a form of language expression,but also a universal cognitive mode of human beings.Book of Poetry,containing a large number of metaphors,is a classical work of human civilization.By studying the metaphors in Book of Poetry,the thinking process of the people in the pre-Qin Dynasty can be fully understood.Based on the conceptual metaphor theory of Lakoff and Johnson,taking Book of Poetry as the corpus,this paper aims to explore the plant metaphors in the poetry.According to the different target domain,in this paper,the plant metaphors in Book of Poetry are classified into metaphors for virtue,for beautiful things,for blessing and for feeling,and some corresponding examples are used to elaborate them.This study is of great significance to the appreciation and dissemination of Chinese classical poetry.At the same time,by studying classical Chinese cultural works,the cross-language and cross-cultural characteristics of conceptual metaphor theory are proved. 展开更多
