Scholars, writers and teachers in the mode

题目：

Scholars, writers and teachers in the modern academic community have p feelings about acknowledging the use of another person’s ideas. In the English-speaking world, the term plagiarism is used to label the practice of not giving credit for the source of one’s ideas. 41．______
42．______In many universities, the punishment may range from failure in a particular course to expulsion from the university. In the literary world, where writers are protected from plagiarism by international copyright laws, the penalty may range from a small fine to imprisonment and a ruined career. Protection of scholars and writers, through the copyright laws and through the social pressures of the academic and literary communities, is a relatively recent concept. Such social pressures and copyright laws require writers to give scrupulous attention to documentation of their sources.
Students, as inexperienced scholars themselves, must avoid various types of plagiarism by being self-critical in their use of other scholars’ ideas and by giving appropriate credit for the source of borrowed ideas and words, otherwise dire consequences may occur. 43．______
Plagiarism by accident, or oversight, sometimes is the result of the writer’s inability to decide or remember where the idea came from. He may have read it long ago, heard it in a lecture since forgotten, or acquired it second-hand or third-hand from discussions with colleagues. He may also have difficulty in deciding whether the idea is such common knowledge that no reference to the original source is needed. Although this type of plagiarism must be guarded against, it is the least serious and, if lessons learned, can be exempt from being severely punished.
Plagiarism through ignorance is simply a way of saying that inexperienced writers often do not know how or when to acknowledge their sources. The techniques for documentation-note- taking, quoting, footnoting, listing bibliography-are easily learned and can prevent the writer from making unknowing mistakes or omissions in his references. 44．______

The opposite of plagiarism is acknowledgement. 45．______Students, as developing scholars, writers, teachers, and professional leaders, should recognize and assume their responsibility to document all sources from which language and thoughts are borrowed. Other members of the profession will not only respect the scholarship, they will admire the humility and honesty.
