| This paper takes the three words of modern Chinese mood adverbs"Daodi(到底)""Daoliaoer(到了儿)""Daotoulai(到头来)"as the research object,based on linguistic facts,from the perspective of diachronism and synchronicity,adopts a combination of description and interpretation,qualitative and quantitative research methods,to study it in detail.The full text consists of five chapters,including:The first chapter is the introduction,which mainly introduces the research object of this paper,its research significance,research status,the theories and methods to be used,and the source of the corpus.For the description of the current research situation,an overview is made from the overall modal adverbs,the sub-categories of modal adverbs "Dao(到)X",and the expression of position,including the academic discussion on the definition and internal classification of modal adverbs,the research on individual modal adverbs,and the use of position expression.A study that analyzes specific linguistic phenomena.It is found that there are few and incomplete studies on the modal adverbs of "Dao(到)X",and the literature on modal adverbs from the standpoint of expression is even rarer.The second chapter mainly analyzes the diachronic formation process of the modal adverb"Dao(到)X"and its motivation from the diachronic perspective.The modal adverb of"Dao(到)X"is a compound word,which is lexicalized from"Dao(到)+X".This kind of word is composed of two Individual content words("Daotoulai(到头来)"with a modal particle suffix"lai(来)"after two individual content words)form a cross-layer structure and are often used as adverbial adverbs in sentences to aggregate into adverbs of time,which are then subjected to subjectivization and other functions to develop tone function of adverbs.Based on the ancient Chinese corpus of Peking University,the paper analyzes the lexicalization process of the three words one by one,and then analyzes the two main grammatical processes involved in the process,namely the evolution of the meaning of the common morpheme"Dao(到)"and the three words.The evolution from time adverbs to mood adverbs.Finally,the mechanism of lexicalization and grammaticalization of the modal adverbs of"Dao(到)X"is discussed respectively,and it is concluded that this kind of words are mainly lexicalized under the impetus of semantic blurring,syntactic position adjacent and cognitive motivation,while grammaticalization is mainly Driven by syntactic positional changes and the principles of language economy.The third chapter analyzes the semantic features of the"Dao(到)X"modal adverbs from the syntactic environment.Using the Antconc corpus retrieval and statistical software to batch process the modern Chinese corpus of the modal adverbs of"Dao(到)X",the syntactic position,the distribution of sentence categories,and the co-occurrence of the modal adverbs of"Dao(到)X"were analyzed,and the conclusion was drawn that"Dao(到)X"Mood adverbs have commonalities and individualities in relative position to the subject,tense and aspect characteristics,semantic characteristics,and emotional color.The difference in the syntactic position of the modal adverb of"Dao(到)X"is mainly affected by its relative position to the subject.The flexibility of its syntactic position is in the following order:"Daotoulai(到头来)">"Daoliaoer(到了儿)">"Daodi(到底)",when the modal adverb of"Dao(到)X"is placed before the subject or the subject is When omitted,the modal adverb is usually located at the beginning of the sentence,otherwise it is usually located in the sentence or as an interjection.In terms of tense and aspect characteristics,the perfect voice is shared by the three.In addition,"Daoliaoer(到了儿)"and"Daotoulai(到头来)"can also be used in the progressive voice,and"Daodi(到底)"and"Daoliaoer(到了儿)"can be used in the past tense.In terms of semantic features,[+consequentiality]([+结果性])and[+tortuousness]([+曲折性])are shared by the three,in addition,[+consistent with expectations]([+符合预期])is unique to"Daodi(到底)",[+bad results]([+坏结果]),[+speculative]([+推测性])are Unique to"Daotoulai(到头来)".In terms of emotional color,the order of preference intensity is:"Daotoulai(到头来)">"Daoliaoer(到了儿)">"Daodi(到底)",and the mood adverbs with higher preference are more negative in emotional color.The fourth chapter discusses the commonality and individuality of the"Dao(到)X"mood adverbs in the standpoint expression based on the standpoint triangle theory in standpoint expression.Among them,"Daodi(到底)"and"Daoliaoer(到了儿)"can express positive and negative positions,while"Daotoulai(到头来)"can only express negative positions."Dissatisfied position"is shared by the"Dao(到)X"modal adverbs,and each word has its own expressive characteristics.The fifth chapter is the conclusion part.Summarize the previous content and summarize the viewpoints of this paper,point out the inadequacies of the article. |
