1。 Introduction

1。1 Research background

Lexicology is one of comparatively significant parts in linguistics, and is also the center of linguistic research。 Considering its ubiquity and complexity in English, synonymy is an interesting but intricate linguistic phenomenon。 Synonyms are the words which are close in meaning, so they convey the same or nearly the same meanings。 Due to this special feature, it is difficult for English learners to indentify correctly and master them properly。 Although the English dictionaries they relay to can give some general guidance to some extent, they still cannot distinguish most of synonyms precisely because of the limitation of space and their basic retrieval function。 So it is difficult for English learners to choose the proper words to express or communicate appropriately and freely。 Besides that synonymy also troubles English teachers in illustrating and teaching。 Therefore, how to distinguish synonyms becomes much more urgent and pressing。

The appearance of corpus linguistics offers the studies of synonymy a brand new perspective。 Corpus is a collection of electronic data selected according to a certain sampling standard, which can represents a certain language due to its abundant and authentic resources covering different registers and convenience for retrieval and analysis。 Corpus offers a great deal of real material about internal usage patterns and unparalleled insight into variations of a certain language, therefore, to some extent it makes up for the traditional synonymy distinction。 With the constantly advancement of the research methods and expansion of the research fields in corpus linguistics, corpus study has become an important means in empirical research。 Through exploring the authentic texts, English users can utilize the contextualized grammatical knowledge acquired in corpora to grasp the way of target language formation。 Besides that corpus linguistics pays quite more attention on syntagmatic relation, i。e。 the meaning of a word is conveyed by the company it keeps, therefore, the analysis of collocation becomes an indispensable topic in corpus linguistics。 Hence collocates of a word lemma and their derived frequency lists will facilitate language learning and teaching。 源Q于W优E尔A论S文R网wwW.yOueRw.com 原文+QQ75201,8766
