However, many previous studies haveindicated some problems in grad
7、uate students MA theses. Thus it is of great necessity tocarry out this study. Most of the previous studies put emphasis on students knowledge andattitudes toward plagiarism instead of analyzing and discussing it empirically. Therefore,this study aims to explore plagiarism in English majors MA thesi

After that some suggestionsare put forward.This study employed the instruments of two corpora and two questionnaires. Onecorpus consis
9、ted of 733 theses from the year of 2000 to 2002 which were groupedaccording to different years, specialties and school types. All these theses were matchedagainst data in the other corpus called “Turnitin” to get similarity index (percentage of theportions plagiarized from others). Then 32 graduates
10、 who have got MA degree were askedto finish two questionnaires about their understanding of plagiarism to exam howplagiarism was understood and implemented at graduate level. The following researchesquestions are addressed in this study:1). To what extent do the students plagiarize others in their M
11、A theses of English andwhat are the differences and similarities?2). What is the students knowledge of plagiarism?3). What are the possible causes for plagiarism?The major findings of the study are summarized as follows:Firstly, 45.6% of the students had a correct citation of others writings, while
12、morethan half (54.5%) of the students plagiarized more than 20% of others writings and neededfurther modifications before oral defense for their MA theses. In terms of differentgraduation years, the plagiarism became more and more serious both in degree ofsimilarity index and number of students. For
13、 three different types of universities, theses in“211” universities were detected to have the lowest similarity index. More students in“985” committed severe plagiarism than other two types of universities. With respect to thefour specialties, the students of theoretical linguistics performed best,
14、followed by theivtranslation students. Theses of applied linguistics were detected to have the highestsimilarity index. As for the distribution of the sources of the plagiarism, “internet” camefirst, “students papers” and “publications” ranked after in the writings of “appliedlinguistics”, “translat

Some students were even not clear about definitions ofplagiari
16、sm.Thirdly, among various causes attributing to plagiarism, easy access to the internetand bad time management ranked the first, followed by a lack of academic writingconventions which corresponded to the second finding mentioned above.Key words: graduate; academic writing; plagiarism; corpusv摘摘要要在科研和教育中，抄袭问题愈加受到公众关注。研究生作为文化层次较高的群体被人们广泛认为已具备本专业基础知识， 应该懂得如何开展研究和合理使用参考文献避免抄袭。但是前人的相关研究显示研究生毕业论文存在着诸多问题，因此，开展本研究就显得十分必要。从目前的相关研究来看，前期的相关研究主要关注学生对抄袭知识的掌握和对抄袭的态度，很少进行大规模的实证研究。本研究采用实证研究的方法，对我国英语专
