A Contrastive Study On Some Synonymous Prepositions "X" And "X Zhe(着)/le(了)"

In this paper, a contrastive study has been made on six pairs of prepositions: "X" and "X zhe (着)/le (了)", which are similar both in form and meaning. They are "chao (朝)", "chaozhe (朝着)"; "yan (沿)", "yanzhe (沿着)"; "shun (顺)", "shunzhe (顺着); "chen (趁)", "chenzhe (趁着)"; "wei (为)", "wile (为了)", "weizhe (为着)"; and "dui (对)", "duizhe (对着)". Eight chapters are included in this paper.In chapter one, the purpose and significance of the research made in this paper are introduced. And the basis of this study, some relevant achievements and the outline of the paper are made clear here, too.From chapter two to seven, these six pairs of prepositions are studied one by one. Firstly, the reason why "X" and "X zhe (着)/le (了)" are chosen as the topic is explained and some relevant questions are raised: What are the differences between prepositions "X" and "X zhe (着)/le (了)"? What is the grammatical status of "X zhe (着)/le (了)"? Is "X zhe (着)/le (了)" a structure or a word? Secondly, based on the language material gathered from corpus and Internet, a contrastive analysis is made on "X" and "X zhe (着)/le (了)", including the number of the syllabus, the nature and semantic category of the objects after them, and the distribution of prepositional phrases of "X" or "X zhe (着)/le (了)". Thirdly, the collocation of the prepositional phrases of "X" or "X zhe (着)/le (了)" with the VP they modify, and the tense and aspect of the VP are investigated.
